554646Okay FLIGHT, you read his pitch and yaw and his high-gain meter.
554651And now you want roll right to 060?
554655Might as well do that. And we'll try and get Comet Bennett, I'd still like the verification on the docking angle because that's what we'll be using for computation for alignments and everything else. Let's see if there's anything else.
554709Okay, let's terminate the battery B charge at 55 +50.
554715And at the same time, I'd sure like to have a cryo stir, all 4 tanks.
554720Let's wait until they get settled down a little more.
554725They would still like to enable the other two quads for the maneuver.
554729Okay. When rolling to 060 you want them to enable C and D, right?
554736Do you want them to disable A and B?
554740They have a coupled jet maneuver -
554747I'd like to confirm their configuration on their high-gain now.
554751I'd like to know what track mode they're in and what SERVO electronics they're in.
554756Okay, let's just standby 1 there. Now we'll C and D for roll to 060, terminate battery B charge.
554810Okay, the third thing we want up there, CAPCOM, is to verify their high-gain configuration. And I assume what you want from there is you want to know their tracking, position of track - BEAM WIDTH you don't need, do you? Do you want the whole works?
554831CAPCOM, we want the configuration of the CSM high-gain.
555012Can we verify that they reenabled C-4 thruster?
555021Okay. Verify that they re- - you're showing that disabled, yes?
555025CAPCOM, we're still seeing CM C-4 thruster disabled.
555035We've got 40 amp-hours back in battery B now.
555044You got it, FLIGHT.
- Likely in response to seeing C-4 thruster enabled.
555055Okay, all flight controllers. I want to go around the horn and pick up anything you need configuration-wise. TELMU -
- you still worried about any configuration items?
555106Negative. The LM heater current indicates that the LM was properly closed out. They apparently have not closed the LM hatch yet.
555116Okay. So you're happy that you don't need them to verify that - what was it, Activation 2-3, those pages we were on?
555123That's right. It was TLC 2, and we're happy.
555132Can we ask about the docking index again?
555135CAPCOM will get that for me.
555157Okay. Got your answer, GUIDANCE?
555233Okay. GNC, you got any configuration items here?
555238CAPCOM, looks like the last item we need here is a stir on Hâ‚‚ and Oâ‚‚ at their convenience.
- The fateful but inevitable request.
555402We finally got a ∆H update. Do you want to just read it up to the crew or uplink it?
555410Let's see, now. Can we collapse deadbands and do all that good stuff if we uplink here?
555419Uh. Yeah. That - why don't we just read it up to them?
555424If they enter it through the DSKY are they gonna do it?
555432Now, we haven't stabled out in that attitude yet, so I don't think we're gonna have any problems.
555435FLIGHT, I don't think there's any problem, they haven't opened up deadbands yet.
555438Yeah, that's just what I'm saying. The time to do it is now, GUIDANCE.
555444As long as he's in P00 and don't reselect it, he can uplink it - enter it himself or we can do it easier. Doesn't matter.
555458Okay. Why don't - you gotta pass the data for the crew checklist anyway on-board, don't you?
555506Don't you got a page update? Well, why don't we read it up to them and that'll serve both purposes.
555511Both have them enter it as well as why don't you tell them what page you want it in the checklist?
555520We show the LM overhead hatch is closed, and the heater current looks normal.
555529We've had a hardware restart. I don't know what it was.
555531Okay. GNC, you want to look at it? See if you see any problems?
555538Roger. We're copying it, CAPCOM. We see a hardware restart.
555542You see an AC BUS UNDERVOLT there, GUIDANCE? Err - EECOM?
555549I believe the crew reported it.
555551We've got a MAIN B UNDERVOLT.
555552Okay, FLIGHT, we've got some instrumentation funnies, let me add them up.
- Having missed the pre-explosion pressure spike on tank 2, all EECOM has to work with now is a Christmas tree of bad data readout. So many numbers were off whack all of a sudden that EECOM assumes it has to be instrumentation. Lengthy discussion ensues on the EECOM loop.
- Poor Sy had a "two-handed deathgrip" on his console by now.
555602We may have had an instrumentation problem, FLIGHT.
555610We switched to WIDE BEAM width about the time we had the problem.
- A red herring, but a believable one if the problem were instrumentation or telemetry.
555642INCO, you say you went to WIDE BEAM width there?
555650Let's see if we can correlate those times. Get the time when you went WIDE BEAM, INCO.
555703Do we have the floodlights off right now?
555706That's affirmative, FLIGHT.
555707Yeah, we can determine that from the LM current.
555737Roger, we copy that also.
555814EECOM, you were seeing any AC problems? Looks like -
- we have a lot of instrumentation problems here. Go ahead.
555818That's affirm. He's flipping out fuel cells around, FLIGHT.
- This ended up being a problem for the flight controllers. The astronauts were doing their own problem solving and configuration changes, so every time the controllers on the ground had a recommendation for them something would get changed and they'd have to start over.
555824Well, let's get some recommendation here, Sy, if you've got any better ideas.
555833Sy, what do you want to do? Hold your own, and -
555841- Sy, have you got a SIG SENSOR type problem there, or what?
555845He's got fuel cells 1 and 3 are offline. We've got MAIN A volts, we have no MAIN B volts. Have them attempt to reconnect the fuel cells. FUEL CELL 1 to MAIN A, FUEL CELL 3 to MAIN B.
- back to MAIN A, FUEL CELL 3 back to MAIN B.
555912Okay, now is there - do we have instrumentation problems?
555917Well, we've lost - it does appear we've lost AC BUS 2 VOLTAGE. MAIN B is reading - 4 volts. And that effectively takes AC 2 away from us -
- the - yeah and he reported barber poles on the -
- on the fuel cell on-board, too, FLIGHT.
555939Let's see if we can get our DC back.
555942Verify that the Quad Delta HELIUM VALVES are open.
555947You seeing an attitude problem or you seeing some BI-levels that are giving you problems?
555951No, it's some low pressures in the fuel and oxidizer which would be symptomatic of the HELIUM VALVE closing and firing some jets.
- Here he means these two things both happening, not that the valve closing would cause jet firing. Helium is used as an inert gas to maintain pressure in many propellant tanks even today. If the helium isn't coming in, propellant gas exits the tank without anything re-entering to keep the pressure up.
- Kranz notes that this was a moment of realization for him; the reported bang must have been pretty strong to have jarred shut the valve. He'd seen something similar on Apollo 9 during CSM/S-IVB separation.
560000Quad number 2 HELIUM VALVE open?
560002Quad Delta - HELIUM VALVE open, right?
560011CAPCOM, do you want to verify the Quad Delta HELIUM VALVE is open, please.
560017Any other problems in the RCS, Buck?
560021Okay, is that all we've come up with for them; have we got any other recommendations?
560026Yeah, we wanted to get FUEL CELL 1 configured to MAIN A, FUEL CELL 3 to MAIN B. Did you pass that up?
560032Let's attempt that, FLIGHT.
560037INCO, this seems to be an AC type problem, it may be tied into that high-gain thing you got.
560046We went to WIDE BEAM WIDTH - FLIGHT - at 55:55:04, best we can tell.
560109Let me commiserate on that.
560116Is there any kind of leads we can give them? Are we looking at instrumentation or have we got a real problem, or what?
- The lack of answer here is telling. At some point here, steely-eyed missile man and NASA legend EECOM John Aaron had gotten called at home. He asked for some numbers to be read out, and while bolting out the door warned them that whatever it was, it wasn't instrumentation.
560136Let's reverse the configuration request -
560138Okay, but wait a minute. We've got a good MAIN A BUS, let's make sure that whatever we do doesn't screw up MAIN A. MAIN A -
560144FUEL CELL 2 is on MAIN A, FLIGHT -
- and I'm not going to ask to change that.
560147Okay, what do you want to do?
560149Let's try to put FUEL CELL 1 on MAIN B, FUEL CELL 3 on MAIN A. We'll use the other sensing circuitry.
560157FUEL CELL number 1 on MAIN B -
560201- FUEL CELL 3 on MAIN A.
560209We're not going to touch FUEL CELL 2, FLIGHT.
560212Okay, but if we got any problems in the system I want to make sure that we don't blow the voltage off MAIN A, then we're not going to be able to see anything.
560228Can we review our status here, Sy, and see what we've got from a standpoint of status. What do you think we've got in the spacecraft that's good?
560236MAIN BUS A is reading 25 volts.
560240And that's reflected by the fact - FUEL CELL 2 is putting out 53 amps, which is just about the most it can and keep our voltage up.
560249So that's bona fide. AC BUS 2 is 0, which is reflected by the fact that we lost MAIN B.
560315Okay. If we want to keep - - standby, he's changed configuration, we've got BATTERY A on MAIN A.
560328That's what I was going to ask you for, to put the battery on, FLIGHT.
560331We need OMNI Bravo. Our high-gain won't drive without AC 2.
- The steerable antenna needed AC BUS 2 to power its servos.
560338Okay. You want OMNI Bravo?
560349You don't think we're going to be able to get HIGH BIT RATE data here, do you? On the OMNIs.
560353We may be. We've got the 210s.
Okay, that'll save a bit of power. CAPCOM, recommend selection of OMNI Bravo, please -
560428Okay, FLIGHT, we've got OMNI Charlie and HIGH BIT RATE.
560431Okay. You have HIGH BIT RATE now off the 210s, right? OMNI -
560500Okay. Let's get a readout on a couple of fuel cell pressures here -
- FUEL CELL 1 Nâ‚‚ pressure. FUEL CELL 3 Oâ‚‚ pressure. We're reading 0 Nâ‚‚ pressure on FUEL CELL 1 and 13psi on FUEL CELL 3 Oâ‚‚ pressure.
- Nitrogen was used to pressurize the electrolytes in the fuel cell through a diaphragm, as well as the reactant feed systems. Feedback loops are set up with the cryogenic oxygen to regulate the relative pressures.
560518Okay, you want FUEL CELL 1 -
- Nâ‚‚ pressure. FUEL CELL 3, what do you want there?
560527Oâ‚‚ pressure. CAPCOM, let's get those as a start.
560535When his hardware restart he was doing a crew-defined maneuver, and that should have killed it, but we're still moving. We ought to stop it.
560545Are we using RCS now, Buck?
560605Did you see any problems in Quad D HELIUM VALVE? Does that look like that's cleared up?
560608Roger, that's cleared up, FLIGHT, we're in good shape.
560610Okay. Now, are we using RCS now?
560612That's affirmative, we're going to have to switch some thrusters to MAIN A to hold attitude here.
- Because the thrusters required electrical power to operate and MAIN B was dead, a lot of them had to be switched around to the other bus to maintain operation.
560617Okay. How much RCS are we using?
560622Oh, we've used - our guess 25 pounds.
560628Okay. Give me minimum fuel usage configuration that'll keep me attitude.
560635The LM heater current's become essentially static.
560638Roger. Let's solve one problem at a time. Come back to me later on on it.
560705We confirming those numbers?
560720Buck, I need that RCS stuff as soon as you can get it.
560723Roger, FLIGHT. He's turned off all jets now.
560726Okay, we came up with those numbers, FLIGHT.
560729Okay, Sy. Give me your next best thing to try.
560751Why don't we try - leave FUEL CELL 2 alone, and just make sure that 1 and 3 are disconnected from both buses. And make sure that there's abs - that there won't be any load on them at all. And let's see what happens to those cells.
- n.b. this is shutting off the output electrical circuit of the fuel cells, not the fuel cells themselves, which remain on.
- Since the fuel cell electricity was produced via a chemical reaction, reducing the electrical output load would reduce the reaction rate, which could have an impact on the problem.
560806Okay, what do you want to do? Open-circuit FUEL CELL 1 and 3?
560810Okay. CAPCOM, let's recommend we open-circuit FUEL CELL number 1 and number 3 and leave FUEL CELL number 2 as-is.
560821Okay, 1 and 3 open-circuit, 2 as-is. And earlier we got a report from them that 1 and 3 were reading grey but zero flow.
- Connected to the circuit. An open circuit would yield a barber pole.
560829Yeah - CAPCOM, let's amend that. EECOM, from FLIGHT.
560833Why don't we just open-circuit 1 and make sure we don't have any problems getting that back onto the bus -
- and just watch it for a while before we make any further moves with 3.
- FLIGHT's caution is probably well-advised here, but the last-minute change is dropped by EECOM; later he still thinks both 1 and 3 have been open-circuited.
560841Okay, CAPCOM. Let's just open-circuit one of those right now.
560905That's roger, FLIGHT. That's the AC problem.
560916Crew thinks they're venting something.
560927Copy that, FLIGHT?
- Pretty much as worked-up as the room gets.
560933Okay, let's everybody think of the kinds of things that we'd be venting. GNC, you got anything that looks abnormal in your system?
560943How about you, EECOM? You see anything that - with the instrumentation you've got that could be venting?
561001Let me look at the system, FLIGHT, as far as the venting is concerned.
561003Okay. Let's start scanning. I assume you've called in your backup EECOMs?
561012Have you called in your backup EECOMs now? See if we can get some more brain power on this thing?
561018He's - he's - never mind, he's straightening up a little bit.
561045Okay, now, let's everybody keep cool. We've got the LM still attached, the LM spacecraft is good, so if we need to get back home we've got a LM to do a good portion of it with. Okay? Let's make sure we don't do anything that's going to blow our CSM electrical power with the batteries, or that will cause us to lose the MAIN - the FUEL CELL number 2. We want to keep the Oâ‚‚ and that kind of stuff working, we'd like to have RCS. But we've got the Command Module system, so we're in good shape if we need to get home. Let's solve the problem, but let's not make it any worse by guessin'.
- Note the repeated use of "if" here. The severity of the problem was not yet fully understood.
- As noted elsewhere, FLIGHT likely meant LM here.
561151I have some jet configurations for you whenever you need them.
561201Okay. Charlie 3, Charlie 4 to MAIN A. Bravo 3 and Bravo 4 to MAIN A. Charlie 1 and Charlie 2 to MAIN A -
561221Yeah; it's all of quad Charlie on MAIN A.
561225Plus Bravo 3 and Bravo 4.
561229Now, what are we going to be doing with these, GNC?
561232That'll give us one jet in each direction on each axis.
561237He's getting close to gimbal lock.
561239CAPCOM - okay, CAPCOM, recommend he bring up C-3, C-4, B-3, B-4, C-1, C-2 on MAIN A and advise him he's getting close to gimbal lock.
561253Could we go to a coarse align on the platform here, so we don't have to use any gas if we need to? We could reorient if necessary.
561302Roger. I was going to recommend a P52 in a little bit anyway -
561305Well, it's going to take a while before we get to the point we're even thinking of a P52.
561312Yeah, it'll coarse align itself there, won't it?
561410Okay, EECOM. I'm coming back to you.
- I think the best thing we can do right now is start a power down.
561420Let's go down the emergency 1-5.
561423You want to power down, let us look at the TM and all that good stuff, and then come back up.
561430FLIGHT, INCO. OMNI Bravo.
561432You want OMNI Bravo again?
561442CAPCOM, recommend OMNI Bravo.
561447Okay. What - you want to go to - power down - give me the page.
561451Emergency 1-5, FLIGHT, we'll go down - try to get a delta of 10 amps reduction.
561513Okay, we've got OMNI Bravo, FLIGHT.
561522EECOM, do you want to go through that again? What do you want to power down to?
561525I want to power down a total of 10 amps, FLIGHT.
561528A total of 10 amps.
- You can hear someone (FLIGHT, perhaps?) whistle in amazement at this.
561535CAPCOM, we'd recommend emergency power down checklist 1-5, we want to power down a total - a delta of 10 amps from where we are now.
561545Can we afford to do a PTC first, and then we can shut off all of that stuff with no problems.
- As FLIGHT notes later, this is not a possible request.
561551Why? You think you're going to have a thermal problem here?
561553Well, we could have - if we stay there too long, or we -
561555Okay, we'll run into that one later, Buck -
- I want to get our major problems sorted out now.
561601You want - you still want 1-5 down to 10 amps?
5616031-5 power down a delta of 10 amps, CAPCOM.
561635You don't want to get fuel cell pumps off, do you?
561644Optics power is already off, I believe.
561647We can do that on FUEL CELL number 1, FLIGHT.
561650Okay, well let's make sure we don't blow the whole mission.
- Kranz himself writes that he realized within fifteen minutes that an oxygen tank had exploded and therefore the "mission" referred to here was now survival, not a lunar landing. But it is not clear if the entire room was on this page quite yet.
561722Would you not want to consider going to PTC?
- Echoing GUIDO's suggestion earlier. Still not possible, as FLIGHT points out later.
561726Well, why don't we get this problem here resolved, right now -
561729This will aid our power down, I think -
- this should aid our power down, I'd hope - wouldn't it?
561737Well, do you expect that we're going to be in a thermal problem for the next many hours? EECOM?
561744Well, I don't know where to say the sun is right now, FLIGHT.
561747Well, it's pretty close to quad A right now.
561753I don't know exactly where. It's between A and B, mostly on A.
- He's likely deducing this from temperature sensors in the RCS thruster packages.
561841Buck, I'd prefer not making any unnecessary maneuvers now, or try to use any of the equipment's on board the spacecraft, such things as CMC, that type of stuff until we nail down what our problem is.
561855Well, that's why I was recommending PTC because we don't need any of that stuff then; heaters or anything else.
- The RCS system involved warming heaters to ensure everything fired as expected.
561859Yeah, but you gotta get the CMC on, and keep it online. And you need a rather precise period of time for redamping there.
561910In the order of about 20 minutes to damp out and then spin up and then we can do without any of that.
561917If we get a good spinup going then we're stable -
561919Okay, that might be a good idea. That would buy us some more time from a standpoint of reviewing the data. And it would get us back into the - as close to the normal flight plan as we could. How far are we out of attitude right now?
561937He's a fair ways out right now, FLIGHT. He'd have to do another VERB 49 and fly back and then stabilize there.
562058Okay, I need one thing right now. He's powering down, he's down to 41 amps, total spacecraft. I'd like to get my AC 2 BUS back so I can look at Oâ‚‚ TANK 2 PRESSURE. I have no insight into that.
562112Let's get - I guess we can put INVERTER 3 to MAIN A. AC 2.
562122And let's just do it temporarily -
562122Now, let me ask you a question - before you do that would you like to make sure you've got all AC load you don't need isolated from the bus?
562132Nah, it - let's not do that right now, FLIGHT. I think we're in good shape that way. The MAIN A is up high enough where it can handle the inverter.
562139Well, the thing that concerns me is starting - is throwing equipment - we had a problem, we don't know the cause of the problem, and -
562145FLIGHT, I've got a feeling we've lost two fuel cells. I hate to put it that way, but - I don't know why we've lost them. It doesn't all tag up. And it's not an instrumentation problem, the best I can tell right now.
- The other shoe drops. 27 minutes past the accident, and the picture is becoming clearer. The situation is dire. Only one fuel cell remains, and the gas for it is leaking slowly out to space.
562159Okay, I'll tell you what. Let's discuss this for just a little bit longer there, Sy. CAPCOM, start them moving back towards a PTC attitude, let's start him going into his rate damping. I feel it's going to be a relatively long period of time to try and nail down the problem. Go ahead.
- What Sy is saying is highly consequential. This is dramatized in the film for the sake of informing the audience. But the decision hasn't been made to irreversibly close the reactant valves and thus shut down the fuel cells yet.
562213He's asking how do we like his amperage setup right now?
562218Are you happy with his power level right now, EECOM?
562230I'd like to - for him to secure the high-gain before he starts getting into PTC.
562254That's affirmative, FLIGHT.
562254GNC? What's firing now? You got something firing?
562258Well, we've seen quite a bit of thruster activity.
562301Okay, I guess this kills the PTC, too, because we're not going to get into PTC as long as we've got something venting.
562311Roger, FLIGHT. That agrees with what we're seeing here.
562315I've got a little correction. Let's put INVERTER 1 on both AC buses, please.
- Earlier he asks for INVERTER 3. Only 1 and 3 could pull power off of MAIN A, and MAIN B is dead.
562320INVERTER 1 on both AC. Why?
562322That's affirm, so I can get some AC BUS power back so I can have some insight into my AC BUS 2 telemetry, especially my cryos, maybe - the venting may be coming from that. And also, I think that the FUEL CELL 2 pumps are on AC 2, and this will take care of it without switching the pumps yet.
- Presumably, he needed the pumps back on.
562344Say that again. You think your fuel cell pumps -
562347Yeah. FUEL CELL 2 pumps I think are on AC 2.
562350Okay, but according to the checklist, he should have powered - he should have turned those off, right? Now, he said he was down to BMAG number 2 is in WARM UP, so he's already gone through the fuel cell pump stuff.
562402Okay, so you want to configure INVERTER 1 on both AC buses.
562421FLIGHT, I didn't - I was listening to the spacecraft and I didn't pass up INVERTER 3 to MAIN A to AC 2, did you delete that?
562435You want to put INVERTER 1 on both AC BUSES. EECOM and CAPCOM, let's do it.
562448Monitor this bear when we switch again -
562459TELMU and CONTROL, from FLIGHT.
- take a look at the prelaunch data and go through your systems and see if there's anything you've got that may have started venting here?
562509Okay. And I want a report on that in about the next fifteen minutes. Quick look type stuff.
562517We're definitely seeing a vent in the data.
562527Roger. We copy that, CAPCOM.
562536Fuel cell - FLIGHT, EECOM.
562538FUEL CELL 2 PUMPS to AC 1.
562540You want FUEL CELL 2 PUMP to AC 1.
562544CAPCOM, FUEL CELL 2 PUMP to AC 1.
562603Have you got anybody getting a delog on this thing downstairs?
- The beginnings of an effort to trace back the data through the accident and piece together what actually happened.
562610Bring me up another computer in the RTCC, will you?
562614We got one machine on the RTCC and we got dual CPs downstairs.
562618Okay, I want another machine up in the RTCC and I want a bunch of guys capable of running delogs down there.
562625FLIGHT, did you hear him say he's getting some rates? We want to know if he's firing any thrusters?
562631Roger. GNC, watch those thrusters, will you?
562635Have you got any thrusters firing?
562637We're looking at that C-3 thruster, FLIGHT. It looks like it stays on most of the time.
562642Well, can we turn them all off and see if we've still got the rates or any build-up in rates?
562646Well, the rates that we're seeing is opposite to the direction of that thruster, so if anything it's just trying to hold and not quite up to it.
- In other words, the venting is pushing in the opposite direction to C-3's firing so they're fighting, but the venting is stronger and winning.
562654He's been trying to counteract the rates with DIRECT. He's been getting a negative pitch and a negative roll.
562706But he asked if we were getting some thruster firings that were not being made by him.
562711I'll tell you what, GNC can you get somebody in the back room to try to figure out what the equivalent ∆V is we're getting? So that we can see if we can backtrack to see if we can figure out what's venting.
- An elegant physics solution, albeit one that would take some time to pull off. In space, absent any external forces and by basic three-laws Newtonian physics, locating single sources of acceleration is a simple matter of running the numbers through basic physics equations.
562729In other words, do - it would seem we could equate that to effective thrust and an axis and then deduce what's venting.
- A vector, in other words, like you remember from grade school.
562736Roger, we'll give that a try, FLIGHT.
562737Okay. And that might be of interest to the LM guys.
562741He also said it was coming past window number 1.
562750EECOM, from FLIGHT. What did - okay, we've got two good AC buses. What did all that tell you, now?
562758It tells me that - well, just give me about 2 more minutes, FLIGHT.
562857Two machines in the RTCC.
563139We would like to turn thruster Alpha 3 on MAIN A and see that'll help control that pitch and at the same time we can turn off Charlie 3 because -
563146Okay. Get me some real-time plotting on how we're using RCS here, will you?
563150Roger, FLIGHT. And in the pitch axis we really don't seem to be using any. And that's why we'd like to go to Alpha and see if that changes it any.
563156Okay, now what do you want again?
563158Thruster Alpha 3 to MAIN A.
563208CAPCOM, do you want to pass that up to the crew, please?
563216Give me a gross amount of RCS propellant consumed so far, GNC.
563223Roger, FLIGHT. It'll take 30 seconds.
563230That's affirmative, FLIGHT. We're still below the limits.
563236We've really got to get that battery off the line and power down some more. And we've got to get some MAIN B power back so we can build our pressure back up in Oâ‚‚ TANK 1. It's down to 318psi.
- Nominal Oâ‚‚ pressure is around 900psi. Normally, an automated pressure sensing switch would activate a heater as the tank depleted to heat the Oâ‚‚ and keep the pressure around that number. 100psi is a bit of a redline mark, at which point even at minimal load only about 2 hours of useful power could be expected.
With MAIN B down, we have no heaters in Oâ‚‚ tanks.
- Heaters could be used to increase the pressure even with less gas (good old
PV=nRT
). But EECOM thinks they are on the dead DC MAIN B bus.
563255Okay, what do you want to power down?
563257Well, where'd he say he got down to? BMAG 2 OFF? Not inclusive?
563300That's affirmative. BMAG 2 is in WARM UP.
563304I think we'll go ahead and turn that down - we still have the LM with us, right?
563309So - if we shut down the SCS we ought to be a little better off, perhaps. I think we ought to press on and go down through BMAG 2 OFF, and get those lights minimum.
563321Okay. How much you want to power down? Another 10 amps?
563324Let's get the BMAG off and get the lights down to a minimum. Let's go down two more steps.
563328Okay. CAPCOM, we want to power down a little bit more. Want to get the BMAG off and the lights minimum there.
563355Okay, Sy. Now, how long do you want to leave this battery online?
563401I want to try and get it off as quick as I can -
- but I need to get powered down.
- The spacecraft is currently drawing too much power for the one healthy fuel cell to supply, so the battery is currently required.
563405The crew did report they removed FUEL CELL 3 - they open-circuited it also, didn't they?
- Here's that last-minute change FLIGHT requested earlier that EECOM missed.
563412FUEL CELL 1 and FUEL CELL 3 should be open-circuited.
563415We just had our last call for FUEL CELL 1 open-circuit, and we left FUEL CELL 3 as it was.
563421Let's take this open-circuit, FUEL CELL 3.
563422Open-circuit FUEL CELL 3.
563430Calling, FLIGHT. Say again?
563434Yeah, we've used a total of about 70 pounds RCS. We'd like to change the jet configurations, see if that'll help us out any.
563444Okay, what do you want to try now?
563445They would like to turn the Bravo jets all to be OFF, and all Delta to MAIN A.
563453Turn all Bravo OFF, and Delta to MAIN A, right?
563457Roger. That will verify that it isn't a Bravo thruster that's causing the problem with attitudes.
563502Okay. CAPCOM, we'd like to turn all Bravo jets OFF and all Delta jets to MAIN A.
563516Let's take BATTERY A off the MAIN.
- MAIN now on the one fuel cell even with the cryo Oâ‚‚ going down?
563526Okay. What's your worry level on cryo Oâ‚‚?
563533I want to save the battery, FLIGHT.
563535Okay. Let's see, what battery have we got online, Sy?
563540What battery have we got online?
563543And next step, of course, we'll then think - we've got to worry about getting some power on MAIN B to get the pressure back up in Oâ‚‚ TANK 1.
563549Roger. Turn BATTERY A OFF, CAPCOM.
563615Let's have them isolate the surge tank also, and save it. We'll use the cryo as much as we can.
- The surge tank provided additional Oâ‚‚, and was located in the Command Module, so it stayed with the crew for the whole flight.
563623Let's isolate the surge tanks -
563626I don't understand that, Sy.
563627I don't want to - I want to use the cryo as much as possible.
563630But that would seem to be the opposite, if you want to keep the fuel cell going.
563634The fuel cells are fed off the tanks in the Service Module, FLIGHT. The surge tank is in the Command Module. We want to save the surge tank which we need for re-entry.
- You can find a detailed diagram of the Oâ‚‚ system, including the Surge Tank, here.
563645Okay, I'm with you. I'm with you.
563648CAPCOM, let's also isolate the surge tank.
563656Okay, you want to isolate the surge tank.
563700Yeah. What we're really doing is securing our entry systems right now.
563727Yeah, we're trying to figure out some way to get power on BUS B.
- Recall that the tank heaters, which are needed to raise the pressure, are thought to be on BUS B, which is currently dead.
563810Would you consider putting a battery on BUS B long enough to get the pressure up?
563814Well, I'm trying - I want to determine whether or not the - the 5 amps is going to hurt us any. That's going to be on MAIN A, incidentally. I made a mistake. Oâ‚‚ TANK 1 HEATERS are on MAIN A.
- Good news, since MAIN B appears to be shot.
563826Well, we've got MAIN A with us, haven't we?
563845Okay. Since Oâ‚‚ TANK 1 HEATERS are on MAIN A, and we've got them off now, we'll be able to stand the 5 amps temporarily for manual pressurization. Let's have them turn the heaters on manually in Oâ‚‚ TANK 1.
- As noted previously, the heaters are normally controlled automatically off a pressure sensor. That automated switching highlights the simplicity of the spacecraft's systems; no computers needed to monitor and react to the sensor: it just plugged right into the activation circuit.
563901And we'll watch the pressure.
563912That's CRYOGENIC Oâ‚‚ HEATER 1, FLIGHT.
563916FLIGHT, we copy that. No problem.
563919CAPCOM, we want to get CRYO Oâ‚‚ TANK number 1 HEATER ON.
563942You can stand the 5 amps on MAIN A?
563945That's affirm. We think so, FLIGHT.
564005Did you see your 5 amp increase in current there, EECOM?
56401226.7 volts, looks good -
- we'll watch the pressure.
564016FLIGHT, to be consistent we ought to isolate the REPRESS package also.
- The repressurization package, like the Oâ‚‚ surge tank, was a reserve of pressurized oxygen gas in the Command Module.
564022Okay, you want to isolate REPRESS pack.
564041Get one of your guys full-time in the back room keeping track of the spacecraft configuration as we pass it up to the crew. You might use Larry. Why don't you stay on, get Larry in the back room to keep track of configuration stuff we give to the crew?
564055And we've got the voice recorder and we're starting to transcribe that.
564059Okay, now has anybody started the delog of the initial problem? You've got a delog going? Have you got people that are going to be in a position to evaluate it?
564119TELMU and CONTROL, from FLIGHT.
564124Roger. I want LM manning around the clock.
564130I want the fans on in Oâ‚‚ tank 1, we're not seeing a pressure increase. We can stand it.
564139Fans on in TANK 1, right?
564144CAPCOM, do you want to bring the fans on in TANK 1?
564146It's just 1 amp, FLIGHT.
564149Okay, he's got an MC&W for - varied reasons.
564221It looks like the vehicle has stabilized considerably over the last few minutes.
564226Okay. That could mean one of two things. Either whatever was venting has stopped venting, it's empty; or do you feel it could also be associated with the thruster Quad Bravo we just isolated?
564239It's possible, FLIGHT. We really don't know yet, though.
564242Okay. Are we essentially in a - can you figure out what orientation we are from a standpoint of thermal control? Assume - what's our rate right now?
- He's referring to the heat and shadow of the Sun.
564252Right now he has a -0.10 of a degree in pitch. And yaw and roll are very close to 0.
564301The pressure in Oâ‚‚ TANK 1 is all the way down to 297, we'd better think about getting in the LM, or using the LM systems. I'm going to have to power way down; I don't know if I'm going to be able to save the Oâ‚‚ for the third fuel cell - for FUEL CELL 2, rather.
- PSI. At 56:32:37 it was reported at 312psi.
564317The heaters aren't working, now let's start thinking circuit breakers. You got any circuit breakers you want to check, there?
- In other words, FLIGHT is wondering if the heater circuit breaker popped, so despite flipping the switch on, the heaters weren't actually running.
564325We saw the current, FLIGHT.
- EECOM doesn't think the circuit breaker theory is likely, since he saw the load on MAIN A increase by the expected amount for a heater to be running.
564326You saw the current - okay, look -
564329Let's check it anyway, FLIGHT, you're right.
- But that could be a coincidence or something else could be wrong, so he comes around.
564331It looks like it's cycling up a PCM count from 297 to 302. Give me some circuit breakers to check.
- The telemetry refreshed and the pressure increased - by a hair.
564337Okay, panel 226. CRYOGENIC Oâ‚‚ HEATER 1, MAIN A circuit breaker.
564346I'm sorry, I didn't catch you there. CRYO Oâ‚‚ TANK 1? Panel 226?
564351CYRO Oâ‚‚ HEATER 1, MAIN A, panel 226.
564356Also, FLIGHT, let's check the FAN MOTOR circuit breakers TANK 1, on panel 226 also.
564407CRYO FAN MOTORS TANK 1. There are three circuit breakers - three phase.
- Three-phase alternating current. Motors are easier built on three-phase AC. Unlike the two-phase AC your house gets, three-phase AC works with three wires.
564418I've got the 226 CRYO Oâ‚‚ HEATER 1 MAIN A, and CRYO FAN MOTORS TANK 1, three of them on -
564425That's right. All three phases.
564429EECOM, I don't think we're going to come to any solution here until we get back to the initial set of conditions, so I hope you got a set of guys looking at the delog pretty soon.
564450I want you to get some guys figuring out minimum power in the LM to sustain life.
- The first mention of this critical problem and need on the loop, but it's nearly certain that the back rooms were working on this already.
564515We got the circuit breakers. All in, FLIGHT.
- The circuit breakers popped out when broken and pushed in when the circuit was closed.
564520Roger. Copy, all circuit breakers in.
564614Don't we have both BMAGs OFF?
564623CAPCOM, would you verify that both BMAGs are OFF, please?
564638You want to bring it off, right EECOM?
564642CAPCOM, let's get it off.
564733Will you get a cockpit panel 1, 2 layout and have the crew - just get the thing and have the crew read across all instruments, all gauges, and write down exactly what they read in those things?
- Panel 3 contained fuel cell readings, which were already being closely monitored, and propellant readings for the SPS, which FLIGHT did not want to use. So there was no need for a survey.
564745Okay. You want a survey of panels 1 and 2 on gauges?
564752Okay. And talkbacks, huh?
564754That's affirmative. Figure out some code that you can use and - I think that's something we should have gotten started a while ago.
564819See that juice is still going down there, EECOM. You got any more suggestions?
564827Any more suggestions in trying to pump up Oâ‚‚ TANK 1 pressure?
564830No. FLIGHT, we're gonna hit 100psi in 1 hour and 54 minutes. That's the end, right there.
565056Whatever planning you do, I want to do assuming that we're going around the Moon and we're using the LM for performing maneuvers, because in the present configuration, unless we get a heckuva lot smarter I think we're wasting our time planning and using the SPS.
565112So I think all of our return-to-Earth type planning should be assuming the use of the LM DPS and/or RCS. And I think third priority down the line should be CSM RCS.
565125Okay, and I'm assuming that you want fast-as-possible return.
565131Yeah, I think that's the case.
565132Okay. We'll work on it from that sideline, FLIGHT -
565147Okay, listen. There is a possibility that we blew a Oâ‚‚ line in one of the fuel cells, and it's effectively manifolded there, of course. Now, I'm - I want to shut off one of the reactant valves to one of the fuel cells. And that would be FUEL CELL 3, since its Oâ‚‚ pressure is gone. Now, FUEL CELL 1's Oâ‚‚ pressure is trying to stay up there, at 45psi. Maybe the problem is in FUEL CELL 3.
- In other words, both tanks run into this line.
565223That sounds like a good assumption, right there.
565225Yeah. FUEL CELL 3 is lost anyways, for us.
565229Turn Charlie 1 thruster OFF.
565232You want to turn Charlie 1 OFF? Why?
565235Well, looks like we're getting a lot of firing out for no reason.
565240Okay, CAPCOM, recommend THRUSTER C-1 to OFF.
565300No. C-1. OFF. I added a word in there. Turn THRUSTER C-1 OFF.
565325Why don't you show me where you think that problem is?
565327Okay. Clint's coming up.
565522Go ahead, EECOM.
- This is actually Glynn Lunney responding, who was preparing for his shift. He spent some time before his team came on circulating the consoles and issuing a single critical question to each that had to be answered in the following half hour.
565523We need to get the - make sure the inline heaters for FUEL CELLS 1 and 3 are OFF.
565549EECOM, from FLIGHT. You want to shut off both reactant valves to FUEL CELL number 3?
565553It's dead anyway, FLIGHT.
565555And the inline heaters OFF in FUEL CELLS 1 and 3, please.
565559What we're proposing here - supposing here, CAPCOM, is we may have a - had some problem in FUEL CELL number 3 since that's the one that's reading no Oâ‚‚ right now. And we may be losing our Oâ‚‚ through FUEL CELL number 3, the Oâ‚‚ manifold - inasmuch as they're manifolded together commonly. Looks like the Oâ‚‚ in FUEL CELL 1 and 2 seem to be trying to stay up there. And FUEL CELL 3 looks like it's the oddball here.
565642CAPCOM, let's close the REACTANT VALVE to FUEL CELL number 3.
565648Okay, close REACTANT VALVE to FUEL CELL number 3.
565652And you're saying that 1 and 2 look okay?
565656Well, what it looks like - looks like the pressure's trying to stay up there and this is the best guess we've got right now because we've got to stop this Oâ‚‚ flow.
565714Some more jet reconfigurations to see if we can hold the attitude.
565718We'd like to turn Charlie 2 OFF -
565720Wait, why are we interested in holding attitude? If we're not venting why not drift for a while? That would probably be better from a standpoint of thermal control anyway, wouldn't it?
565727I'd think we'd like to get into a controlled drift rather than just some random thing, FLIGHT.
565755Do you want them to go through that whole smash for fuel cell shutdown, Sy? I assume you do - heaters and all?
565802That's affirm, FLIGHT. He's gone through much of it already, got the pumps off.
565805Okay. You want them to go through the whole fuel cell shutdown. Heaters and all.
565808Roger. Heaters, reactant valves, and the pumps of course he's already got.
565812Okay. Have them go ahead, CAPCOM.
565814And get the inline heaters OFF on FUEL CELL 1 also, FLIGHT.
565818Inline heaters OFF on FUEL CELL 1.
565821Roger, it'll cut the current requirement down that way.
565855Their COMM holding up? Sounds like he's going out.
565858How you doing there, INCO? From a standpoint of OMNI-switching?
565901We might be a little better on Bravo.
565903Okay. Can you figure me out some way to keep communications and yet cut down a bit on the load? You might talk to EECOM on it.
565911Okay. We can turn the tape recorder OFF.
565915You don't need the tape recorder, do you?
565920It may be already off, but that's one thing we don't need.
565923Let's go down the list as much of that INCO stuff as we can get, FLIGHT. I think that's about the one biggie right there.
565930I think that's about the only thing we can give up. We turn the POWER AMPL OFF, we won't get HIGH BIT RATE.
565936Let's also verify tape recorders OFF, please.
565941I don't think we got down that far on the list, did we? We went through the BMAGs and that was lights - BMAGs and lights, and I think we stopped right there.
565949Yeah, that's affirm, FLIGHT. Tape record - we'll skip a step and go tape recorder OFF.
570011AFD, meet RECOVERY. RECOVERY loop.
570023What was that, GUIDANCE?
570024He had an 06 18 he couldn't get rid of; he's gotten rid of it now.
570117Okay, FLIGHT. I had them reading off a lot of gauge readings, and we got over to FUEL CELL 3. And I hope your people were copying all this down.
570126Did you get some kind of master? We got it on tape, I'm sure we can get it off the tape.
570132Alright. That's affirm. I'd say I have 95% of the ones he read.
570219When the systems men can stand it, I need two minutes for a checkpoint to save all this data.
570225I don't see why we couldn't - EECOM, GNC, can you stand a checkpoint right now?
570235It only takes a minute, I guess I'll have to if we need it, FLIGHT.
570238Yeah, I think it'd be good to get a checkpoint. Go ahead.
570240EECOM, have you deduced anything - have you seen your REACTANT VALVES go off? You seen flow cease?
570251They were open-circuited, and the pressure - still appears to be going down.
570338We'd better confirm that the FUEL CELL 3 REACTANT VALVE circuit breaker on panel 226 was closed when he shut those.
570346FUEL CELL 3 REACTANT circuit breaker on what panel?
570353They're normally open.
- To avoid accidental shutoff of the reactant valves, the electrically activated shutoff valves were normally open-circuited and had to be closed in order for the shutoff switch to actually do anything.
570359You want them - close the circuit breaker -
- on the valve, and then -
570404Yeah, FLIGHT; he should have gotten a barber pole on that.
570416Yeah, wouldn't he get a barber pole when he turned the reactants off? EECOM?
570423Even with the circuit breaker open?
570425No. Okay, so he ought to know that. We can just verify that he got a -
- The rest of the sentence here would have been "barber pole."
570434Okay, FLIGHT. We have our checkpoint.
570436Okay. All flight controllers, I'd suggest you start handing over, because I think a fresh team's probably going to be thinking clearer. I think the rest of us can continue working in some other function in support of the new team coming on.
570448Go on thruster A-4, FLIGHT.
570450Okay. Go on thruster A-4, CAPCOM.
570452Roger. And OMNI Charlie.
570500FLIGHT, he wants to bring on A-4, he hasn't got any way to stop the pitch rate in DIRECT or AUTO.
570531I never got a call for OMNI Charlie, you want it?
570612Okay. All flight controllers, I'm handing over to Glynn. I assume the majority of all the team guys are pretty much briefed and up to speed as best we can. Now what I'd suggest is the white team do two things: they go over the delogs - okay - let me go back over this again. We're handing over to Glynn. I'd suggest the white team goes back and starts going through the delog of the data. In other words, let's see if we can go back to the initial conditions and work on that problem to see if we can find out what happened and we may find some better clues as to what to do and let the fresh guys come on and try to figure out where do we go from here.
- Kranz's team was the white team. Glynn headed up black team.
570651And the delog is in way now. Roger.
570712Okay, EECOM. Tell me about the latch. Do you think you've got the reactants latched?
- FLIGHT is following up on the possibility that the reactant valve didn't close. There was, in addition to the breaker, a latch that could wedge it open to prevent it from closing in case of heavy vibration, as could happen during a burn.
570720The crew reported he got barber pole whenever he threw the reactant switch, so that implies that he did all the right things and he really got it shut off. And it looks like that didn't help us any - the pressure's not improving any.
570735Okay, now the next question is: are you willing to do that on FUEL CELL number 1?
570740That's the question we're pondering, FLIGHT. We've got to come up with an answer on that one. Soon.
570746FUEL CELL 2 is working okay.
570749Unless we do something to get that oxygen, it's not going to do us any good to save fuel cells.
- In other words, there's no reason to be reluctant to shut off another fuel cell if there won't be any oxygen to feed into the working one anyway. You can already see how much more Lunney opines on debates.
570755Okay - okay. GNC, FLIGHT.
570800You stabilized now? - standby.
570805Here comes configuration, I think it's yours.
570833I didn't copy all those; did you, GNC?
570835Roger, FLIGHT. We concur.
570837Is that good? How are the rates?
570840It's holding down around a tenth of a degree per second, FLIGHT. Oscillating, he's in ACCEL CMD, so -
570855FLIGHT, did you copy all those thrusters?
570857Go ahead. Who's calling?
570900CAPCOM. Did you copy all those -
570901I didn't copy them all, Jack. GNC, did you copy them all?
570904That's affirmative, FLIGHT.
570905Do you like that configuration for right now?
570908As best you can tell - best you can tell, the rates are okay. And he's flying ACCEL CMD.
570918No rate damping, then, right?
570922Are both BMAG packages off?
570944Standby. EECOM, you need anything?
570949Roger, FLIGHT. We'll take those.
570957Get him to go through the meters -
571000Okay. Just FUEL CELL 1 and 3, Jack.
571123EECOM, I don't like the way that Oâ‚‚ pressure's going down. If you want to do something about these other reactant valves, let's make up our mind.
571131Let me get that for you in a minute, FLIGHT. Let's standby on these readouts.
571134Yeah, okay. Anybody can copy the readouts. Be sure you're discussing these reactants.
571152Hey, FLIGHT. CAPCOM. Long time ago I heard someone mention something about closing the REPRESS package and then we never made a decision on that. Do you want to do that, too?
571205Do you want to close out the REPRESS pack? I think that came on for them before.
571209We indicated earlier that we'd like to get it closed off -
571223Okay, on the reactants for FUEL CELL 1. Seems to me we have no choice but to go ahead and do it. The pressure continues to drop. We're not going to have anything left soon anyway. So, looks like the next best thing to try is to go ahead and turn the reactants OFF on FUEL CELL 1.
571241Yeah. What is this pounds on your display, Clint?
571247That's - that's invalid.
571255And of course, you'll want to make sure that his circuit breaker is closed for FUEL CELL 1 when he starts to close the reactant valves.
571302Which circuit breaker is that? The one on 226?
571308That's FUEL CELL number 1.
571310That's right, FUEL CELL reactants number 1.
571314Is he done with that readout yet?
571318I didn't copy the last part of it there, FLIGHT -
571332Is there any chance that I'm just looking at a bad pressure reading here? I'm going to shut off the second fuel cell now, is there any data you can correlate that says that yeah, that pressure is going down?
571349You understand my question?
571350I understand your question. The temperatures are also dropping. Let me get a verification on that - standby just a minute.
- The ideal gas law
PV=nRT
can help verify the two readings against each other.
571413Yeah, we copy that. Tell them we're debating shutting off the reactants on 1.
571418The temperature is the only thing we have.
571422You're saying that I'm looking at a valid pressure in that tank, and it's still going down.
571426That's the way it looks, FLIGHT.
571428Therefore we need to go to FUEL CELL 1 and turn off the reactants.
571432CAPCOM, FUEL CELL 1 reactants. Circuit breaker and a switch.
571436Okay - you want them to go through the fuel cell shutdown procedure on 1?
571441Do you want them to go through the fuel cell shutdown procedure on 1?
571449Because the tank 1 is still going down. Pressure and temp - pressure going down, temperature confirms it.
571505Of course, you want to ask yourself if you want to open 3.
- Open-circuit FUEL CELL 3, perhaps?
571512Yeah. You don't want to do that?
571514Negative, let's leave 3 like it is.
571529What MAIN BUS do you want up?
571533Just like it is. FUEL CELL 2's on MAIN A.
571602How long can I leave that stuff off and still turn it back on? Any time at all?
571606Negative, FLIGHT. It's like it wipes it out.
- As dramatized in the film, once the fuel cells are shut off they're done for good.
571621I don't know. That's what I'm asking, but we've got that shut off now.
571706You're ready for that now. Sure, absolutely, huh EECOM?
571710It's still going down and it's not possible that thing is sort of bottoming out, is it?
571715Well, the rate is slower but we have a little less pressure too, so we would expect it to be a little bit slower.
571721You are sure, then; you want to close it.
571724Seems to me we have no choice, FLIGHT.
571731Standby one minute; I'll poll my back room.
571732It went down again. One more.
571748We're go on that, FLIGHT.
571750Okay. That's your best judgement; we think we ought to close that off, huh?
571754It's dropping down to 234. Yeah. Okay. FUEL CELL number 1 REACTANTS coming OFF.
571819I think we can help the CMP a bit if we can tell them to enable B/D ROLL in the DAP. He's got A/C turned OFF and he's got A/C selected in the DAP. Can we tell him to -
- To instruct the DAP that it was allowed to use RCS packages B and D for roll control.
- The A/C ROLL thrusters were disabled entirely, but the DAP was being asked to use them for roll control.
571828Is he under DAP control?
571830Well, he goes to it occasionally -
- he's in - RATE CMD right - ACCEL CMD right now, but -
571835Okay. Okay. He's got A/C off, huh?
571839CAPCOM, when you get a spare minute there, Jack needs to enable B/D ROLL in the DAP if he wants to use it.
571845If he wants to use the DAP, that is.
571853Jeez, it's really going down.
571917Okay, is the - LM gotten all set up for using LM systems for supporting the CSM?
571926Okay. We'll get you time as to what it looks like we'll have for power here, shortly.
571931TELMU and CONTROL, FLIGHT.
571935Keep reminding me of that heater; now I don't want to let that thing go too long.
571938Okay. We're still trying to get some data - substantiating data on that, FLIGHT. My own personal opinion is the sooner we can take care of that, the better off I'm going to feel about it.
571947Yeah, okay, Hal. Go get 'em.
571950Okay; and FLIGHT, TELMU. We're working on a procedure right now that powers the LM internally from its own power.
571958Save you a little more power to turn the HIGH GAIN antenna switch to OFF.
572004POWER switch. You're doing okay on the OMNIs, huh?
572007Yes. We've got the 210s.
572009Okay. CAPCOM, he can turn the HIGH GAIN antenna POWER switch OFF; we're doing fine on the OMNIs. We've got the big dish.
572016Like to charge BATTERY A.
572017Yeah, I was wondering about that. Do you - let me get the HIGH GAIN POWER off first, okay? Clint?
572031How much - how many amps will that give us, EECOM?
572034About 1.3, 1.4 amps - - amp-hours per hour. The cost is about 1.5 amps.
- The rate of battery charge.
572041So it's no big deal on the amps.
572043That's right. And we'd like to use whatever time we have to put energy back into the battery.
572048Yeah, and I see Oâ‚‚ tank 1 pressure is 217.
572051That's affirmative. It's still coming down.
572106GUIDANCE, you want anything done with the CMC right now?
572110FLIGHT, we would like a VERB 74 before they power it down.
572117Standby, FLIGHT, let me the flight - site configured.
572131Does the temperature in tank 2 correspond with the pressure reading?
572134Let me see how close it is, FLIGHT.
572200Temperature and pressure correspond - they verify that the pressure reading's right.
572211That's right, FLIGHT. Tank 2.
572213Okay. Now, is it possible that we still have that tank and it's good? And we could somehow get power on B and use it?
572221It's not likely, FLIGHT.
572223What's not likely, Clint?
572224Not likely to be able to - actually have anything left in the tank.
572231I don't think so, but let's - we'll pulse (??) that one to you.
572234Let me get you a time it looks like we've got on tank 1 here.
572258Is there anything simple that we can refer the crew to to get them thinking about using the LM here? Have you got anything in the checklist, paperwork that'll describe to them what your intentions are?
572311Negative, there's nothing documented in contingency. We're thinking about using the LM as a lifeboat, we have some procedures here. On the ground, though.
572318I'm sure you do. What do they amount to? Flying with the tunnel open?
572321Roger. Just a LM, low power - low - supplying power to the CSM.
572327Supplying power to the CSM?
572334To their MAIN BUS B.
- Which hasn't actually functioned since the accident.
572335Okay. Where did - well, MAIN B is in bad shape. We don't have anything on MAIN B right now. What's that power for? TELMU?
572346Just anything they might need it for.
572350What power do you need from the LM?
572406FLIGHT, EECOM. Looks like we've got about 40 minutes left in that tank.
572415Like to get battery A on charge, FLIGHT.
572444CAPCOM, just for his information we're not going to do a DPS burn until we hook around the Moon. Let them know that. And that's at about 79 +30.
- This later turns out to be incorrect. FLIGHT is thinking of the PC+2 burn to send the spacecraft home from the far side of the Moon, but one correction burn ends up happening before then to get the spacecraft back on a return trajectory as early as possible.
572524We didn't get a good recording on that VERB 74, we'll need them to do it again.
572531We'd like to get BATTERY A on charge, and we'd like to go ahead and get some more power off if we can. I'm not sure what the situation is on getting the computer up -
572539Clint, let me ask you now, is there anything you want to do - trying to pump up the other tank? Anything? Are you satisfied that both of these tanks are going down and we're past helping them? Even with batteries? That's what I'm getting at.
572553I'm trying to be sure that you're satisfied that there's nothing else we can do.
572556About all we can do is power down and let heat leak help us some - which is probably going to be trivial.
572602Okay. There's nothing else you want to try.
572606That's the only reason I'm delaying on this BATTERY A charge, Clint; to be sure you've gone through everything and you don't have any other tricks up your sleeve.
572614Okay, what other power do you want to take off before we start the charge?
572618Well, looks like we're going to get into the control area. Whatever they can give up we'll have to come up with, here.
572623Okay, are you ready to go ahead and charge BATTERY A?
572626CAPCOM, why don't they get all they can in BATTERY A?
572629Okay, and Jack also asked me if we wanted to get a P52 and get the LM platform up with the -
572635What do you think of that? GUIDANCE?
572638CONTROL. Question is, do you want to do a quick P52 on the CSM so that we can do an align to the LM? I don't know if we want to keep that LM platform up all that time anyway.
572647Negative, that's too much power in my mind, FLIGHT, to keep that thing running for all that time.
572651Okay, therefore you don't -
572653My vote is not to do that.
572655Okay, CAPCOM, we don't see any need in doing that, because we wouldn't be using the LM platform until about 79 hours.
572703Okay, you don't want to worry about the LM platform. We'll align it later with the AOT, huh?
572740Did you say BATTERY A charge?
572743Okay. EECOM, we charging A? Watch it, there, okay?
572745I'm watching; it's fine.
572752Go one more time around that room. We're letting this thing go down, although I realize we don't have any more thoughts to do, but I want to be sure that if there's anything we can do here, that we're doing it. To keep your -
572803Just power down, FLIGHT. All we can power down will put us in that much better configuration.
572808Okay, I got that part but are there any other things that you can do besides that, is what I'm getting at?
572814Okay. GNC, can you help EECOM there as to what else you might power down, if anything? I don't know whether you can or not.
572819Roger, FLIGHT. We'll work on that, although we're in an ATTITUDE HOLD situation here, and I'd hate to give up the CMC and the IMU right now.
572829Yeah, well the CMC doesn't matter.
- The SCS can perform an ATT HOLD without input from the CMC.
572834Okay, we'll work on it, FLIGHT.
572835FLIGHT, we're not going to have anything in about 40 minutes here.
572858Okay, we've got an update on the time. Looks like we've got about 18 minutes until we get down to 100psi, and that's the cutoff point.
572904Alright. But we're charging BATTERY A.
572906Well, that doesn't mean much in 18 minutes, though. But we're doing all we can do.
572910Alright. CONTROL and GUIDANCE, one more time.
572915Will it do any good at all to - TELMU, FLIGHT -
- join in here. The question is, should we try to do a quick align with the CSM and do an alignment in the LM? Can we keep an alignment in the LM up until 79 hours? Can you keep that kind of power on?
572932The pilots are reporting it's difficult to do that alignment from scratch in the LM docked.
- Astronauts were in the MOCR providing advice; in this case the docked configuration occludes vision and reflects light in a way that makes the alignment telescope hard to use.
572939And we got a tradeoff here as to whether we can stand that kind of power.
572956FLIGHT, GNC. We'd save a little power if we turn all the jets off in QUAD C. We're pulsing those jets and we suspect that we've - closed the PROP ISOL VALVES in QUAD C so it's doing us no good right now, so we need to turn off all the jets in the quad.
- The implication is not that they have chosen to close the valves, but that they have jarred shut. And in this case, to reopen them would require the dead DC MAIN BUS B.
- Even with the propellant feed lines closed, with the thruster still on power would still be spent powering the solenoids in an attempt to fire.
573013Oh, okay, you mean RCS SELECT -
RCS SELECT AUTO ?? check.
573027EECOM? Any need to dump water?
573034Negative on that, FLIGHT.
573035No sweat there, Jack.
- CAPCOM Jack Lousma, still on shift since before the accident.
573047They get the POWER AMPL off? I heard them talking about it a while ago. I don't know.
573052We can eliminate that since we're in the 85 foot gainway.
573057That's not exactly true -
We're looking at it to see how far down we can go.
573103I believe GNC has got some things we can turn down here.
573105Yeah, he just - AUTO RCS in Quad Charlie can go off; we've got that Quad PROP ISOL'd. Which I didn't know, but.
573112Quad Charlie AUTO RCS - GNC, FLIGHT.
573119Confirm: Quad Charlie is PROP ISOL'd off, right?
573123Well, we haven't confirmed that, FLIGHT, but it appears that that's the situation we're in. The shock of the Oâ‚‚ thing, it probably closed those valves -
- and we haven't been able to open them because those are powered off of MAIN B.
573140But A appears to be working okay.
573142Okay. We think Quad Charlie's PROP ISOL'd off, Jack, so in that case we ought to turn off the AUTO RCS SELECT; that'll save a little power. Probably not much.
573153Yeah - you want AUTO RCS OFF on Charlie?
573156How about antennas? How are we doing? Did I hear them give me some bad COMM there?
573202We're in pretty good shape right now, FLIGHT.
573206Let me try one more time. Is it possible that if we got power to MAIN B that we could get TANK 2 powered up and up the pressure?
573216We don't feel like that's a possibility, FLIGHT. We might conceivably get power to B but we don't feel like we can get anything out of TANK 2.
573224Okay, now why is that? Tell me why. I'm just -
573227It's because the numbers we're looking at indicate that it's essentially ambient.
573238GNC, watch we don't pick up any rates now, will you please?
573253How long have we got now in the cell?
573255Last account we had 18 minutes, let me get an update.
573257Okay. TELMU, what have we got to do to power up to get some COMM on the LM?
573301Okay FLIGHT, we've got a procedure here that gets power up first on the LM.
573316Yeah, that gets us power but what do you want up? Just the COMM?
573320We'll have to have an environment for the crew, the way this can be -
573323That's what I'm asking you, EECOM and TELMU. We've got to figure out how - we're just about out of CSM talkin'.
573330What do you want them to power up in the LM?
- our input is, here, that we'll have to live out at the LM.
573354We've got a power up procedure here from TELMU but we've got to start thinking about what you want pow - configured in the ECS and the COMM.
573401That gets power in the LM, and then we'll get you some COMM and TM here.
573404Yeah - do we need to send any power to the CSM? For the platform, or anything? Or, can we even do that?
- Sending power back over to the CSM wasn't part of the original design consideration.
573412I'm not sure we can do that yet.
573416That was a long time ago.
573417Okay. When do you want them to start working on this procedure?
573420Well, tell them they gotta start thinking about the power - going over and powering right now because they're going to have lights problem in a little while in the CSM.
573426Okay, I'll send it up. And they wanted to know if we wanted them to try to reset the PROPELLANT VALVES in the secondaries.
573437That won't do any good because we lost MAIN B and those valves are powered off of B.
573439No - no, CAPCOM. It's off MAIN B.
573535Does this title - this PG&E (??) page - mean anything more than just power up the LM?
573553We'd like to go ahead and power down the CSM all we can except leave that battery charger on. Of course, leave a little light because we're going to be there in 15 minutes anyway.
573602CAPCOM, we're going to out of power in the CSM in 15 minutes in the fuel cells. We want them to start getting the tunnel clear and get ready and get over there and power up the LM as soon as they can, they ought to send somebody over there. EECOM, what ought they do to leave the cockpit?
- At this point, the CSM is clearly a lost cause. But in the 15 minutes of power left, the controllers and crew need to ensure that the spacecraft life support, illumination, communications, and navigation are all ready to go in the LM, or the crew will be flying blind in every possible way: unconscious, in the dark, with no support or instructions from the ground, and with no idea which way the spacecraft is pointing.
573616EECOM and GNC. What ought we do to leave the CSM cockpit? We're going to lose power on the buses, now what do you want to switch off?
573626Power it down, FLIGHT. All of it.
573627The CMC and the IMU, mainly, FLIGHT.
573842Last ditch stand on Oâ‚‚ tank 2, let's turn the fans on.
573846That'll cost about 1 amp.
573848What are they off? MAIN A?
573852Okay. Fans in tank 2 ON.
573901Tell them to try the fans in tank 2. They're off the AC and last ditch stand we'll try the fans in tank 2. Turn the fans on in TANK 2, it only takes 1 amp.
573925TELMU, GUIDANCE, and CONTROL; FLIGHT.
573928Do you know status of the CSM platform right now?
573932Negative, FLIGHT. It's - good as far as we know.
573937No, no, no. Do you know its orientation? Do you know its orientation?
573942Yeah. You know what you've got, and it's okay.
573950Did he get it? Fans 2 ON?
573953He got it, did he, Jack? Number 2 fans?
573958GUIDANCE, CONTROL, and TELMU. The point is, should we, quick - if you guys can't run out the power study, run out - align the - your IMU to the CSM while we study the problem? See what we got in the way of power?
574012Tom Stafford is concerned that they'll have a hell of a time getting the platform aligned in the LM with AOT.
- It was already known that sun glare could cause problems finding star positions with the vehicles docked. On top of that, debris would prove a huge issue once this procedure was actually attempted.
574020Okay. What should we tell them to do?
574023It's going to take about 15, 20 minutes as I understand it to do that procedure, that right GUIDANCE?
574029How about you give me an Activation page?
574031Well, how long does it take to -
- how about a coarse align? At least you get - at least you start it up in -
574035Okay, that's in the ballpark, FLIGHT; that's correct.
574037Okay, now. What do you - what do we do to get this done? EECOM, you got all my power in the LM with that procedure? What power have you got on the LM?
- It's possible FLIGHT meant to ring TELMU here.
574046We ought to go ahead and go a P52 first in the CSM and get -
574048That's what I'm asking you -
- do you know? Well, do you have one now? We don't have much time! Do you have a good one now? As far as you know?
574056Yeah, that's what I'm asking! Do you have a good alignment?
574101And I'm not worried about the tenths of a degree, either.
574104Well, it ought to be that good, FLIGHT.
574105Yeah, okay. So we don't need to do a P52 -
574108Okay, we need to open up the surge tank. The manifold pressure is dropping.
574115Uh - okay. Wouldn't you rather power that from the LM - pump that up from the LM?
574121Well, we - - we've got to get into the LM first, FLIGHT.
574126CAPCOM, get them going in the LM. We've got to get the oxygen on in the LM.
574143Okay, we have a procedure here. Probably the easiest thing is to refer them to Activation -
- 11 and Activation 12.
- If you want to follow along these Activation pages, they start around page 6 of this PDF.
574152What will that do for us?
574153That gives them the COMM -
574203And cross out the VHF stuff.
- does that give us ECS also?
574208That gives us glycol circulation.
574210Okay, how about ECS? Come on, I need some oxygen.
574213Disregard the surge tank request.
574217Do I need some oxygen right now?
574218Roger - just go to Activation step 1.
- TELMU probably did not mean to say "step" here.
574226And go how many steps? Activation -
574235Activation 1, step 3, FLIGHT.
574238And then what? Activation 11?
574249I've got Activation 1 step 3; Activation 11, 12, 13 step 1.
574253Roger, and FLIGHT, in Activation 11, omit step 1.
574258Okay. That'll give them what, now; glycol flow, COMM, and some ECS? Is that right? That's what we want.
574306Okay. That's what we want.
574324One other input: we also need the DEMAND REGs to CABIN.
574352Do you want them to do Activation 1 down to step 3 - TELMU?
574408And DEMAND REGs to CABIN.
574416TELMU, when do we do DEMAND REGs to CABIN? That's the end of those three steps?
574419At the end of the sequence.
574420At the end of the sequence, DEMAND REGs to CABIN, Jack.
574424And I - I'm still not satisfied he's got Activation 1 down to step 3.
574434FLIGHT, EECOM. The voltage is going to begin to drop and we'll need to power down with it.
574440Okay. What do you want them to do? Turn everything off?
574442Leave the lights on, and - leave the lights on. As far as they need it.
574445And what are they powered from, the LM?
574448They'll be powered from the CSM as long as we have anything. We will bring up BAT A when we get down about 25 volts or so.
574456Until they get into the LM and keep their lights up and whatever they have to have.
574500We don't want to destroy the IMU alignment in the CSM right now, so we've got to keep that up, I assume, until you get the LM aligned, right?
574509We'll do that by bringing BAT A on MAIN A.
574511Well, we'd better quickly do that or we're going to be losing it.
574513We've got 3 or 4 minutes, FLIGHT.
- FLIGHT appears to laugh at this line.
574516But the thing is, we want to pass to them - when he does see it go down. Or, start going down. To get BATTERY A On.
574523Now, you think we really want to spend that to keep the platform on? We're using the entry batteries, too.
574528What we take out of the battery we won't get back.
574534No. Down to step 3. Down to step 3. All the way down to step 3.
574546Yeah. Alright, okay. I just want to be sure we're sure we want to do that. And quick, get a coarse align. CONTROL and TELMU, will the steps I got give me a coarse align?
574600Will those steps that we've passed so far get me a coarse align?
574604Negative, that just gets you -
574606What else I gotta do to get a coarse align?
574609Can we get those read up to the crew to start the power down? Of course, they can power down everything, but here's a good start.
574615?? the battery will drain as they power down?
574619Okay, but we wanted to keep that up for a little while, I thought you just said, with the BATTERY A. To get a coarse align on the LM.
574625Well, maybe there's a bit of confusion here.
574627Yeah. You just gave - you don't want to turn the IMU off until we get a coarse align on the LM, right?
574632That's affirm, FLIGHT. And we'll support a battery until you get that.
574634Okay. CAPCOM, we want to power on down the CSM only. We want to put BAT A on - about now? EECOM?
574641Negative, not yet, FLIGHT. We'll let you know.
574643We're going to put BATTERY A on - can you put it on while it's charging?
574647No. We'll have to take the charge off.
- Starting here, two EECOMs are active on the loop. Maroon EECOM is John Aaron.
574651We'll have to power down the charger and put it on MAIN A.
574702The VHF is not required, FLIGHT.
574725Look, it's unclear enough to me that I'm going to try to get a coarse align in the LM. You know where we are, then, right, Will?
574730Alright. Now, what do I have to do to get it?
574732Okay, I'm getting you that step right now, FLIGHT.
574737When we get a little lower, we're going to have them pull BAT A off, and we'll get him to put it on MAIN BUS A. We are then going to try to hold up the IMU long enough to get a coarse align in the LM, and then we'll see whether we're going to keep that coarse align up or not, but for right now we're running the profiles and we'll have to determine that.
574752Think that's the course of action, let Jack know that much.
574754Okay. And he wants to know what he's going to see and what he should do when he sees it happen to FUEL CELL 2.
574801We're interested in keeping up the IMU and the lights, for him to see. That's all.
574807EECOM, GNC: everything else goes off? INCO?
574813GNC? Anything else goes off?
574816The only concern we have, FLIGHT -
574818I just - yeah, go ahead.
574820- is the IMU heater power. And - for the CSM.
574826Well, if you want to maintain the IMU for re-entry, we've got to have the heater power on.
574831Standby, we'll take a look.
574843FLIGHT, EECOM, we can take it off at any time.
574850Okay, I need some LM IMU align procedures.
574856We need to go ahead and start that power down any time.
574900Okay, do you want me to put BATTERY A on yet?
574902Negative, we'll give you a cue on that.
574903Okay. Where do you want me to tell them to start, Clint?
574906Keep your lights up and everything else has got to go.
574909Everything else except the IMU.
574914How about the COMM? We don't have COMM yet with the LM.
574918As soon as you take that POWER AMPL off we're going to lose data.
- The downlinked telemetry feed.
574921Okay, well let's - yes, let's be clear what we're doing here.
574925We're discontinuing BATTERY A.
574929Okay, so far I've got the IMU and the POWER AMPL up. Anything else?
574937That should do it, FLIGHT.
574939Leave the PCM up, too. Leave the COMM configuration alone.
574942Yeah, leave the COMM configuration alone, CAPCOM, until we get COMM with the LM.
574950Okay, we've got one more - we want to make sure his SUIT FAN 1 is - our SUIT FAN is positioned to 1.
- In both spacecraft, the suit fans were run open-circuit with the entire cabin to scrub the air when the astronauts were not wearing suits. This is the answer to the oxygen request from earlier.
575000And the - on panel 11 we want ECS SUIT FAN 1 breaker closed.
575005Okay, you want SUIT FAN number 1 on.
575008With the breaker. Go ahead, CONTROL.
575009Okay, FLIGHT, here's what we need.
575011Alright, standby. CAPCOM, in the LM we need the SUIT FAN number 1 and its circuit breaker on to get flow, and CONTROL's coming to me with the IMU procedure. Go, CONTROL.
575023Panel 11. LGC/DSKY closed.
575027That's the circuit breaker?
575031Okay. Then go to Activation page 25, do steps 1, 2, and 3.
5750361, 2, and 3? And what will that get us?
575039Okay, that'll get everything up and running and the platform turned on.
575043And will that get us a coarse align?
575044Negative, that'll put you in P00.
575048Docked IMU coarse align procedure is there for you.
575052Excuse me - 30. That's Activation 30, FLIGHT.
575056Okay. I've got LGC/DSKY close, Activation 25 steps 1, 2, and 3, Activation 30.
575102Okay, TELMU, one more question. Are we bringing up glycol flow here?
575106We brought up circulation. We have not activated the boiler.
575109I don't know; we're working on it, FLIGHT.
575113Okay, when we go through this power down when we bring BAT A up, we want them to go through the fuel cell shutdown procedure for fuel cell 2, just in case the pressure should recover and we would still have a fuel cell later. Which is not likely, but it's not going to cost us anything to do it except a little time.
575129FUEL CELL 2 shutdown; that closes the reactants?
575132I'm - I'm sorry. STANDBY. STANDBY's the word.
575140You want me to put fuel cell number 2 on STANDBY when? After we put BATTERY A on?
575145How close are we to doing that?
575147Well, we're looking for it any time now.
575201Have we got anybody over in the LM yet, Jack? Can you tell? Somebody climbed over there? They're both over there?
575206Yeah, we've got them both over there, and they've just taken the procedure for the activation of the IMU.
575213Yeah. Okay. I don't know how long we'll be able to keep that up, but at least we'll have something.
575219Okay, and what other things you've got to go up that I missed while I was talking?
575236Have we given them the signal on the battery yet?
575243About another 20 psi, FLIGHT.
575244Yeah, GNC, FLIGHT. What do you want on the heater? Circuit breakers?
575248I have them still working on that, FLIGHT. We're trying to get it - find out if we can power them down and bring the platform up later on, whether we've really got a problem there or not.
575256Alright. Go ahead. Well you'll have BMAGs.
575318We can turn the GLYCOL PUMP off anytime.
575327BYPASS on the primary rads.
- Radiators, which cooled the water/glycol coolant.
575329Turn the GLYCOL PUMP off.
575331CAPCOM, he can turn the GLYCOL PUMP off in the CSM.
575337BYPASS on the rads, and then turn the pump off, huh?
575341Okay. BYPASS, and then PUMP off.
575345Okay, we should be okay thermally in the LM vehicle until we get telemetry, and we'll watch it until we tell you to turn on the boiler.
575354Okay, fair enough. You can look at TM before you tell me about the sublimators. Thank you.
575359BYPASS and the GLYCOL PUMP coming off.
575410Okay, FLIGHT. Anything else I missed while I was talking to them there?
575413Uh, I don't know, Jack. I haven't been following everything you've said, you did tell them that we're going to be putting BATTERY A on to keep the IMU up. I don't know how much time we've got here; another 20psi was the last I heard.
575425Yeah, and I'm standing by for a mark on that.
575427Yeah. How much power have we got left on in the CSM, EECOM? We haven't got a lot on -
575432We've got about 40 amps.
575433Okay. What else can we take off right now?
575436We passed the list to CAPCOM while we had the IMU heaters - IMU on it. Everything on that list but the IMU.
575443Yeah. Got it, Jack? You want them to start powering that stuff down, right Clint?
575451Okay, Jack. Everything but that IMU.
575515You're giving up there, huh?
575517CAPCOM, Oâ‚‚ FANS 2 off.
575521Oâ‚‚ TANK 2 FANS can go off. There's nothing happening there.
575525That's confirmed. All FUEL CELL PUMPs off, FLIGHT. That's 1, 2, 3.
575529You want to shut 2 down, now?
575531Just the pumps. Just turn the pumps off.
575532Oh. Just the pumps. Okay. All FUEL CELL PUMPs off, CAPCOM. That may be a verify.
575536Okay, verify all FUEL CELL PUMPs off, and -
- fans off in Oâ‚‚ TANK 2.
575600FLIGHT, INCO, we have the LM downlink coming in.
- Good news; the beginning of communications with the Lunar Module.
575608We don't want them fans and heaters in TANK 1, do we?
575612EECOM, you don't want anything on in TANK 1, do you? Or do you?
575615Roger, we want them all on.
575617Leave them all on in TANK 1, CAPCOM.
575624I'm still seeing 40 amps. What all have we got on there, EECOM? CMC? IMU?
575632IMU and CMC still up right now.
575637Look, I'm worried about shutting this thing down so that it's safe when we want to repower it from the entry batteries.
575642Roger. We don't - we're going to ask you to bring up BAT A whenever we see the voltage begin to drop off.
575646I understand that, I still want some kind of closeout configuration. Okay?
575651GNC, same with you. And I haven't heard from you on the heaters yet, on the IMU.
575655Roger, FLIGHT. Preliminary look at it, looks like we can pull all the circuit breakers - power down the heaters. But we're still trying to get a handle on it.
575702We may well have no choice.
575705I don't know - how many amps do they take?
575710I got - I'm looking at a hundred and - I'm looking at - fif, sixt, 80 hours!
575716That's academic!
- Given the LM had a total battery capacity of around 2,250 amp-hours, running the heaters at 10 amps for 80 hours (10 amps × 80 hours = 800 amp-hours) was too much to even consider.
575720Okay, I've got a procedure for COMM activation; 28 on the panel here. It came from somewhere, is this something you want to go up?
575728INCO, is that the COMM activation in the LM?
575729Negative, FLIGHT, the COMM activation is the same as you've got over there, except we want to change to NORMAL VOICE when he gets squared away. I gave him some steerable angles in case we want to activate it. So I have it - and that's the procedure.
- CAPCOM
- Angles to point the steerable S-Band antenna at.
575739Can we go on the OMNI right now?
575741Roger. As we come up around to Goldstone with the 210 we'll be alright.
- The Goldstone MSFN site in Southen California.
575744We have AOS with the 210 now, FLIGHT.
- For the last 10 seconds or so noise has been creeping into the audio. This is the link with the LM coming in. The cause of that noise will become a critical question and problem in the coming hours.
575746We'll stick with the OMNI, yeah, Jack. So don't do anything with that.
575749FLIGHT, we have OMNI data on the LM right now.
575755We've got a better number on that heater power; it only draws about 0.8 amps. So we'd like to leave that up.
575804The temp looks good. 129.9.
575806Okay. 0.8 amps for the rest of the mission is going to cost me 64 amp-hours. GNC, FLIGHT.
575815It's going to cost me 64 amp-hours.
575821I can't afford that! Can't I bring it back up without them? Is that absolutely known?
575828Yeah, I think you can, FLIGHT, but the platform's way off -
575834Turn around here a minute. He's talking about the IMU heater, it's going to cost me 0.8 amps, I'm - 142 hours at landing - I'm 80 hours away. That's 64 amp-hours.
575846Can you hack that out of the entry batteries?
575849We might hack it transferring power back from the LM to the CSM, but we can't hack it on the batteries.
575854FLIGHT, EECOM. Since it's only 0.8 amps let's hack it for a little while here. Then we -
575859Okay, FLIGHT. It looks like they are still on low-volt taps. We need to get the Activation step 12 substep 3 and go to high taps on the LM batteries, 1 through 4.
575913You want the high taps on the batteries, 1 through 4?
575915Roger, that's Activation 12 step 3. Looks like they're still on low taps.
575959CAPCOM, did you give them that about the high taps?
580002I gave them that about the high taps and heard them going through it -
580007FLIGHT, looks like we're going to high taps.
580016INCO. We'd like to get normal voice on the LM on panel 12. FUNCTION switch to VOICE.
580026Okay. Everybody in the room, how about sitting down a minute, and just keeping it a little bit quiet?
580034All our systems look real good on LOW BIT RATE.
- Not that low bitrate is good, but that with the limited data they have on low bitrate things look healthy.
580039We need SUIT GAS diverted to CABIN.
580042SUIT GAS diverted to CABIN in the LM, CAPCOM.
580058Okay, they're doing the coarse align now. CONTROL, can you see your platform?
580102Negative. We're on LOW BIT RATE.
580106We don't have resolvers.
580110Okay, we want them to go all the way through to the fine align, past the angles test so we can get a good alignment with the CSM because that CSM is continuing to move.
580118Which step do you want to get to?
580120We want to go all the way through to step 7 in the LM Activation.
580129All the way through that, Jack, that's what he means.
580145Okay, we expect to put the battery on any time now. We're still going to give you a cue on it.
580205While they're working the problem, do you want me to leave BATTERY A on MAIN BUS A?
580213When we give you the cue, we'll put -
580217Is that what your plan is?
580218Until we get - until we get through to the LM, that's right.
580221Okay. Now, doesn't - GNC, I wanted to hear from both you guys whether you want to leave that on the whole time, but we can stand 0.8 for now on the entry bat.
580229Roger, FLIGHT. We're - we feel like we'd probably be able to power it down.
580237We indicate he still has the LDG RDR HEATERS on; he can open those up if he desires - panel 11 row 3.
580244They're in the middle of the align.
580246But remind me again in a minute, CONTROL.
580323Are we still a ways from the mark on BAT A?
580325I don't know. EECOM, how far away from BAT A?
580328FLIGHT, any time now, but the voltage is still up. We'll cue you.
580332Okay, well, I'm afraid it'll go fast, aren't you?
580335Well, we - it'll go pretty fast when it gets there.
580338CAPCOM, you primed Jack about BAT A, haven't you?
580341I told him we'd give him a mark on BAT A. He wanted to know what to watch for. He'll see the voltage drop but we'll give him the mark.
580349O₂ to N₂ ∆P is dropping; let's turn BATTERY A on.
- The drop in nitrogen pressure, which was used to regulate differential pressures in the fuel cell, indicates the oxygen supply pressure is failing.
580408GUIDANCE, copy the numbers.
580414GUIDANCE, copy those numbers.
580434You got BATTERY A on there, EECOM? 11 amps.
580436That's affirmative, FLIGHT. It's on.
580451Let me know when they're all done and you've got what you want in the LM, because I want to get that CSM powered down.
580456Okay. We can't watch the LM, FLIGHT, we don't have the HIGH BIT RATE.
580458Okay, but from the voice.
580502We can get HIGH BIT RATE from the LM.
580506Does it cost me any power?
580508No. We'd like for him to go to panel 12; we'd like to go FUNCTION switch to VOICE, and HIGH BIT RATE on PCM.
580516INCO, EECOM. Meet me on number 1.
580518They want to go to HIGH BIT RATE in the LM. Won't cost us any power. And they can tell a little more.
580541And, FLIGHT, we checking his arithmetic? On the -
580551Standby, we'll check it.
580558If we can get LOW BIT RATE with the POWER AMPL off, let's turn the PRIMARY POWER AMPL off on the COMM system. There's no sense in -
580608LOW BIT RATE. DOWN VOICE BACKUP.
580611You need him to do that?
580613Okay, CAPCOM. LOW BIT RATE. DOWN VOICE BACKUP, and POWER AMPL OFF in the CSM.
580621INCO, EECOM. Meet me on number 1.
580627We need to get the SUIT GAS DIVERTER to CABIN.
580638CAPCOM, LM: SUIT GAS DIVERTER to CABIN.
580648GUIDANCE, how's that arithmetic?
580650It looks good, FLIGHT.
- Not nearly the snappy slide rule action seen in the film.
580654CAPCOM, the arithmetic's good.
580657Does that mean we've got an alignment now?
580701We've got a coarse align, FLIGHT.
580730As soon as we've got the alignment and we're finished with it we're going CMC OFF, IMU OFF, we'll leave the heater circuit breakers on and power them from - BATTERY A. Until you tell me whether we need to keep them up or not.
580743How come we're getting so much noise on the COMM?
- Again, an important question.
580750We'd like them to do a COMMAND RESET on the CSM so we can get the LOW BIT RATE.
- An answer to a completely different question.
580756I thought we just told them that.
580758We did, but the way the commands work and everything -
580801Alright. They're in the middle of it, I'll get it in a minute.
580858We're turning off some more of the instrumentation, gentlemen.
580902GUIDANCE, have they got the fine align down to where you want it, yet?
580905FLIGHT, we need him to read the angles to us. We've lost CSM data; we don't know what the CSM got on the 06 20.
580913Okay, you really need that, huh?
580915CAPCOM, they need a VERB 06 NOUN 20 on the CSM. We lost it.
580926Here they are.
- Turns out, Jim is already on it.
581006You got everything you need, GUIDANCE?
581012We're ready to go ahead and power down the CMC now.
581015Wait a minute. I want to be sure the guidance is alright.
581027GUIDANCE, can one of you tell me if you've got everything you need?
581030FLIGHT, GUIDANCE, we got everything.
581034We're working on it now, FLIGHT.
581035Now - my question really is: when can I turn the CMC off? Are we that far enough through the procedure that we can turn it off? Yes or no, that's all I'm -
581045Roger, FLIGHT. We are, FLIGHT.
581049If you get us that COMMAND RESET we'll get some data; we're blank here.
581052Okay. Well - in the CSM, you mean?
581055We're turning it down anyway, right now, Ed.
581058CONTROL and GUIDANCE, one more time. You've got everything you need through to fine align and we can proceed to power down the IMU in the CSM, correct?
581104That's affirmative, FLIGHT.
581105That's affirmative, FLIGHT.
581106Okay, and we'll leave the heaters on. Heater power circuit breaker on in the CSM.
581109Check the LM LDG RDR heater breaker also.
581112Yeah. CAPCOM, for the CSM. We've got the fine align data and everything is set up so therefore we can start powering down the CMC and the IMU. For now leave the heater circuit breaker on, and the BATTERY A on the bus like it is. We're running that IMU heater to ground to see whether we need to leave that on or not. And here's the - paper -
581134We got the go ahead to turn the heater power off.
581136IMU HEATER power to OFF.
581138And we'll still have it?
581139That's right. We feel that we have a real good chance of bringing the platform up in good shape.
581143Now, do you want more time to debate it? I'm willing to give you 0.8 of an amp.
581146I don't really know how much debate really needs to be done on that.
581150FLIGHT, EECOM. We need some data. We need to get the LOW BIT RATE - I think we need COMMAND RESET.
581156CS - CAPCOM, CSM COMMAND RESET, and then give them those instructions. We've got enough, we might as well save what we can on the battery now, and power down.
581205You want the CMC and IMU powered down?
And heater circuit breaker -
- heaters off. Off on the -
581210And all the heaters, etc.
581213And COMMAND RESET before they -
581215And you want BAT A, huh?
581305Okay, we've been watching glycol temps and I guess we'd better go ahead and crank up the water boiler. This is Activation 20 - - Activation -
581317And Activation 21 step 3.
581335Do you want to leave BATTERY A on? EECOM? Is that still the story? For how long?
581339That's affirmative, FLIGHT.
581340How long will you want to do that?
581341Until we get squared away with the LM.
581343Let's get all RCS AUTOs OFF, the 16 plus the 2 FDAIs OFF.
- Overlooked is that between turning the CMC, IMU, and RCS all off, the spacecraft loses all attitude maintenance as the LM systems are not yet fully activated.
581403Yeah. Before we turn his thrusters off in the CSM, CAPCOM, you'd better verify they've got some control in the LM.
581410Plus, they need to bring up the water boiler. Go ahead, calling, FLIGHT.
581414This is CONTROL. You mentioned them powering up the RCS; is that right?
581421We're going to have to do that.
581428CSM data - CSM data, FLIGHT
581438Heaters, fans, Oâ‚‚ TANK 1 off.
581451Yeah, have him go and get that stuff off.
581508AUTO - all the AUTO RCS and the heaters in TANK 1.
581545They've got to get the power off as soon as they can.
581547Yeah. Well, we just handed it to the CAPCOM.
581605Okay, did you copy we need to crank up the glycol loop?
581612Under glycol loop activation. And Activation 21 step 3.
581619Down to step 3 or step 3 only?
581621Activation 20 and Activation 21 step 3 only.
581705CAPCOM, FLIGHT. For the LM, he needs to get his sublimator up -
581714Jack, the LM needs to get the sublimator up. Activation 20, and 21. For 21, step 3 only. Go ahead, EECOM.
581721You can go ahead and get those Oâ‚‚ TANK 1 heaters off soon. That's a big chunk.
- Of the 20 amps still being drawn.
581728You want Oâ‚‚ TANK heaters off -
581731Okay. And Activation 20 and 21 step 3.
581734Yup. Get the sublimator up.
581739We need to get our RCS heaters on. Start those warming up. And get the RCS system pressurized, if we're going to be going out of CSM control here very shortly.
581752That needs to be taken care of before she goes.
581824Oâ‚‚ TANK 1 heaters and fans.
581849Go ahead - that was to the - that was for the CSM, that FDAI.
- FLIGHT (incorrectly) thinks the crew misinterpreted the circuit breaker pull request as an instruction for the LM. In fact, the given abbreviated procedures never power up the LM FDAI in the first place.
581902And for the LM, CAPCOM, we need RCS heaters on, they need to pressurize the RCS to have control. And for the water sublimator, Activation 20 and 21 step 3.
581912Okay. I gave them 20 and 21 step 3 already -
- and you want RCS heaters on in -
581918Yeah, RCS pressurize - we didn't tell him to pull the FDAI in the LM.
581923Yeah. Does he understand that? Does that - Jim, does - has he -
581947CONTROL, do you want them to power the balls up and RCS?
581952Definitely the RCS, FLIGHT.
581953Well, they need the ball to tell where they are.
581955CAPCOM, yeah, get a ball up in - one ball up and RCS heaters. And press.
582000And they need to have all of the circuit breakers in for the ISOL VALVES and the main SOVs, FLIGHT. On panels 11 and 16.
582010Okay, in an orderly fashion, please. Ready. What you want, FLIGHT?
582015Okay, how's the CSM? Anything for the CSM?
582020I think we're ready to power the main buses down. If everybody's ready.
582023They don't have attitude control in the LM, FLIGHT.
582025Let's be sure we have control in the LM. Although he's probably out of jets right now. GNC, you got anything for the CSM?
582032Okay, CAPCOM. For the LM, we think he ought to have an eight-ball, and we ought to get his RCS heaters on, his RCS pressurized, and he needs to get all his circuit breakers on 11 and 16 closed for control.
582044Yeah, and Jack, what we're talking about is the QUAD HEATER breakers, the MAIN SOVs, and ISOL VALVE breakers on panels 11 and 16.
582053Don't you have an Activation page I can just tell them to turn to?
582056Yeah, if you want to close all those dadgum breakers. On that page. And then he can go back and open them all up later, the ones he doesn't need. That's Activation 22 and 23.
582121EECOM, GNC, copy his question?
582127Jack wants to know how we wanted to proceed with the SCS. Go ahead, John.
582144CONTROL, FLIGHT, you giving us something for getting your RCS up?
582148Hurry up, will you please?
582150We've just got a lot of traffic for the CAPCOM, that's all.
582216Okay, FLIGHT, GNC. The CMC and the IMU are completely powered down at this time.
582242FLIGHT, put the TCA breakers in last. The TCA breakers in last.
582248Okay. TCA breakers in last.
582332Okay. CONTROL, do you understand the configuration we're getting into?
582337Do you understand the configuration we're getting into?
582340Right now, as I understand it, we're getting into a PGNS attitude control mode -
- it'll be ATTITUDE HOLD.
582346Okay. My point is - let's be careful with what we're telling the CAPCOM to do here; try to give him as clear instructions by switches or Activation pages as we can, okay? Now -
582356Okay, but the circuit breakers -
- are all botched together on these charts, FLIGHT -
582359I know. Okay, you're ready to power down the inverters, the BATTERY RELAY BUS, and you're ready to pull the entry battery off.
582406That's right. Now, that's not what gets him completely configured to do it, but I think we've got to get off entry battery and then do it with voice, FLIGHT. Through the LM. COMM. That's going to kill COMM and everything.
582415Yeah. You're ready to do that. Is everybody ready to kill COMM in the CSM? GNC?
582421You ready to kill COMM in the CSM?
582428We're going to turn down the CSM.
582435Yeah; I want to be sure we've got control somewhere. I'm not satisfied we do yet. Attitude control.
582450Okay. We haven't got ourselves into a position here where we have no attitude control in either vehicle, have we?
582456I'm waiting to see when we get attitude control in the LM. Would they - would you ask them to call us when they have attitude control in the LM, and then we'll power the inverters, et cetera down in the CSM?
582507Okay, once they get control established, we're going to do some setup work as far as loading the DAP to get his -
582514I just want to get attitude control first.
582516Roger. He's had to put his PGNS MODE control switch to ATT HOLD.
582545Hey FLIGHT, they don't have attitude control in the - we don't have CM/SM -
582550Yeah. Okay. Well, they're trying to get it up, right?
582554Okay. I just - what you want to know - pardon -
582615We're getting pretty close into gimbal lock, as I understand it. We need to get that RCS pressurized and on the line -
582620Yeah, well, they're on the way of doing it.
582628He didn't have a ball to do it with.
582630He's got the DSKY, FLIGHT.
582634No - who he? CSM or the LM?
582640Go ahead - wait a minute, GNC. Yeah, we're having a control problem. What's the best way to get it; are you saying the LM, CAPCOM?
582651He can go DIRECT RCS, FLIGHT.
582653CAPCOM, have him go DIRECT RCS and hold attitude in the CSM.
582739We're going to have to have AC here, for this.
582759Both of them go in, FLIGHT.
582806Roger, his LOGIC POWER breakers should be in. A and B.
582809A and B LOGIC should be in.
582845Okay, FLIGHT, we've got a procedure here for the AC coming at you.
582858CAP - he needs AC for the eight-ball - CAPCOM. We need to get AC powered up in the LM. I'm sure they know the procedure, but there it is.
582921What's our current level in the LM?
582930We show him still armed. We'd ask him to go MASTER ARM off.
582958Okay, we've got AC, FLIGHT. Looks good.
583014We see the pyros are disarmed now, FLIGHT.
583051Do you want him to do that?
583052The checkout? There's no need for it, FLIGHT. All we need to do is -
583056He wants to know if you want him to go down Activation 37.
583101Is he - has he got control now?
583103Negative, he does not. I don't think he has his TCA breakers in yet.
583106Okay. But what do you want him to do?
583108I want to get his TCA breakers in after he's got everything else configured, and then he can be in - he'll be in PGNCS ATTITUDE HOLD.
583131Anything needs to be done in the DAP?
583133Yeah, we're going to have to load the DAP, FLIGHT.
- This trickle of piecemeal this-then-that is why FLIGHT indicated a preference for the prewritten procedures.
583136Well, do we want to be in PGNCS ATTITUDE HOLD? Before we load it? Come on, now -
583142We've got the TCAs in now, and everything looks real good right now, FLIGHT. We can load the DAP with no problem.
583145Okay, what numbers you want them to put to get it?
583147DAP data load is for - this configuration is 30120.
583154Right. And we'll have to give you some weights; we don't have those yet.
583214Do we need a weight to go in there?
583220What do we have on weight?
583244Okay, are we ready to go to PGNCS ATTITUDE HOLD now?
583248You ready for PGNCS attitude control now?
583250He's in P00 now, he - he's in ATTITUDE HOLD right now, FLIGHT.
583304Tell - be sure he tells Jack that.
583333Couldn't really copy - did he mention he was having a problem firing his jets?
583336I don't know. I didn't hear.
583339He's asking if he's firing.
583341Need to - make sure his ATCA (PGNS) circuit breaker is in.
583347Okay, what other control circuit breakers do you want in?
583350If he's having trouble, check his ATCA (PGNS) circuit breaker.
583352ATCA (PGNS) breaker on panel 11, row 3.
583359ATCA (PGNS) and what else?
583400And the ATTITUDE DIRECT control breaker - he's got that if he's got DIRECT right now.
583432Okay. That must have been what it was.
583443Okay, can we check the switch configuration circuit breakers and the black boxes to make sure everything's configured correctly for attitude control?
583449Yeah. I'd like to be sure the LM is okay while we power the CSM down, now.
583500Okay - yeah, I heard him holler up the tunnel.
583502Yeah. CONTROL, are you okay?
583504Yeah, we've got one TCP switch failure -
583507Well, we look okay now, and we'll need another DSKY entry here very shortly to inhibit our upward-firing jets.
583512Alright. TELMU, are you okay?
583515Roger, FLIGHT, we're doing pretty good. I've got to get with you in a little while on -
- high ASCENT Oâ‚‚ pressure.
583520Yeah, okay. GUIDANCE, you okay? We're good in the LM?
583524Okay. GNC and EECOM. We're going to power down. You ready?
583536Okay, FLIGHT. They've got attitude control in the LM now. What do you want to do with the CSM?
583540Okay, here it is, right behind you, Jack. For powering it down. There's the paper.
583612Are there any switches you want in the off position before we power down? Like, for example, compressors or anything?
583617No, FLIGHT. Let's just power - this down, we'll fix it later -
583755You want them to open-circuit fuel cell 2, right?
583758That's affirm, if he hasn't done it.
583816We okay there with them? Right now?
583827Just close the REAC valves, FLIGHT.
583830Just close them. Just close the REACs.
583854We lost both CPs. We'll be up in a minute.
583859We just lost data in the building, gentlemen. It's the CPs. Standby.
583910My problem, next, when I get around to it with you guys, is going to be what configuration to power down to.
583918At the present time I'm thinking I'd like to keep the LM IMU up through the burn -
- The PC+2 burn around the far side of the Moon.
583927- we're up on the CPs. But that's about as far as I've thought it through. Everybody's running power profiles, and Jim McDivitt's people have those set of numbers right now.
583938Okay, FLIGHT, we're working on it.
583959EECOM, are you all the way down yet?
584003We think the inverter went off, FLIGHT. So he's in the process.
584020Copy, CAPCOM. Thank you.
584041We - good LM data? EECOM? TELMU.
584045That's affirmative, FLIGHT.
584048FLIGHT, INCO, we've got a problem.
584101We going to have good data here for a while?
584104In and out, FLIGHT. We've got a different problem. By turning off the CSM, we end up without any good tracking data. There's no way we can get any tracking data. That LM data is biased because of the uplink shift, and data select cannot use that tracking data.
- Normally, the telemetry signal contains a base frequency carrier signal whose doppler shift can be read to help track the spacecraft's position through a ranging system. But they had to shift that base frequency -
584119Consequently, somewhere in here we're going to have to bring up some kind of tracking on the CSM again.
584126Would you figure that out?
We're well clear now of the Moon, right?
584132Roger that. As far as we can tell we are, FLIGHT.
584134And we need to - why can't we track this LM? Because of this LM interference - this IU interference -
- - because the radios on the LM and the IU on the S-IVB boost stage (also on its way to the Moon) operated on very similar frequencies, which caused interference. Normally, the LM would not be powered up until the S-IVB was out of range (in this case, it would have impacted the Moon) so this would not be a problem.
584140That's right, because we had to bias off the up frequency to change it down, making a bias in the data; that data's no good.
- Ultimately, this frequency shift allows communication but precludes that tracking methodology.
584146Is it possible to go back to the original and just leave this - IU -
584149We already tried it, FLIGHT. We tried -
- it already. Doesn't work.
584152Okay, Ed. Thank you.
- If you want more background on this problem, this Honeysuckle Creek article starting about halfway down the page is an excellent, detailed account. The rest of it is also worth reading, generally speaking. As well, this article goes into some more of the technical specifics.
584159Okay, everybody, look. We've got a number of long-range problems right now. We have the burn to do, which is at about 79 hours: 28 hours from now. And that's one business. We have to get the track up as we need it to take care of that burn. Hopefully we won't need to do too much with that, although I don't know how many amps that's going to take.
584218However, right now, I want to be sure that we get the whole situation stabilized with the LM and the CSM. We've got to start bringing the LM power down some, and get any non-required stuff off the line so we don't use up any of these amp-hours that we don't need to give away. And I want you to pay attention to the configuration we're currently in and get the people offline working on the longer-range problems, especially the lifeboat problems now associated with the LM.
584247Let's get all that figured. But right now I want the guys who are in the room to concentrate on keeping this thing right now going along all right, and watching it.
584302Okay, are my gyro torquing angles still good?
584305GUIDANCE, are those gyro torques still good?
584308And the crew wants those?
584309Roger. We ought to go ahead and fine align that platform.
584313Okay, and on these - Fred asked the question, he'd like to pull some circuit breakers on displays and have us watch them; is he clear to do that?
584324Do you have good data there, and we can pull the display circuit breakers in the cockpit?
584329Roger, FLIGHT. Just about ready.
584331Okay. I want you to tell me what circuit breakers to pull, and I want them - defined as to panel and so forth, just like we did in the TCP, so there's no misunderstanding there. Okay?
584345Once you get them, TELMU.
584421That's Activation 40, FLIGHT.
584529Okay, FLIGHT. Do you want them to proceed with IMU fine align as outlined on page 40?
584534Roger, FLIGHT. That's what we want them to do.
584550TELMU, FLIGHT. Did you come up with those circuit breaker labels?
584553FLIGHT, we're working on them right now.
584555What do you mean? Don't you know what the circuit breaker numbers - names are?
584558Yeah, there's a whole slew of them -
- what we're going to do is just give you a page of them with -
584603- breakers: open circled.
584605Okay, I'm looking for panel - system - breaker name.
584610Yeah, they're going to give you a picture of the panel with -
584611We're just going to give you a picture -
- with the breakers circled.
584617Do it just like TCP at the Cape.
584626While you're doing that, have somebody else figuring out what we might take off here to save some current.
584636Same with you - we're going to want to save some power here, so -
584639Right. We're working on it.
584640Figure out some suggestions.
584731Jack, would you let me know the conclusion of whatever discussions you guys had about - alignments? When you get - come to one?
584740Okay. I'll wait until you -
584921FLIGHT, RECOVERY. Did you call?
585039Okay, we'd like to have an E-MOD DUMP for the LM, FLIGHT.
585043And we're ready for it at the site.
585045Okay. We'll let - give them a little while, here.
585049Okay, we're tracking a little problem here on ASCENT Oâ‚‚ TANK 2 -
585052GUIDANCE, remind me of that in a little bit.
585054ASCENT TANK 2, what is -
585056The pressure is up higher than it should be, what we need to do is open ASCENT -
585103Before you go through the valves, what are you trying to accomplish?
585106We're trying to use the ASCENT TANK 2 pressure instead of the DESCENT tank.
585110Is it close to venting?
- Most of the tanks had a rupture disc that would blow out at a high pressure, in a way that would be more controlled than the tank bursting entirely.
585113No, it doesn't - it's not venting, now.
585121And it's not broken. Okay, what we're trying to do is relieve the pressure in that tank, so we want to close the DESCENT Oâ‚‚ TANK VALVE and open ASCENT Oâ‚‚ TANK 2.
585137Oâ‚‚, tank 2 - how high is it?
585143And you just want to use some of that and then we'll go back -
- to normal configuration, huh?
585158TANK 2 looks a little high, so they want to use some of it.
585203Close the DESCENT Oâ‚‚ and open ASCENT -
585231Is it a good idea to close the DESCENT Oâ‚‚ VALVE now?
585240He had to go that way, FLIGHT.
585242Yeah, I know that, but I'm worried about it coming back open.
585307FAO pointed out here - we are drifting around here on this middle gimbal angle - he's in MIN IMPULSE right now, and I'm assuming that's where he wants to be, but if he doesn't watch it close he can get himself into gimbal lock again real easy.
585322He's not in an automatic ATTITUDE HOLD mode right now, he's in a drifting flight mode.
585327Yeah. He may be looking for stars, that may be -
585329Okay, but it might be worth a confirmation - okay, he knows that he's in there because he's hitting the ACA right now. Okay.
585336Okay. How's he doing on the middle gimbal?
585341Alright. Is he away from it?
585343Okay. Well, keep your eye on it, Hal. That's good.
585347Just sing out if you think he's getting close and we'll pass it up.
585357If you get a minute, I've got one little item here.
585359Okay. How many amps are we taking out there - standby.
585602CONTROL, did you have something for me?
585603Yes, sir. When we pressurized the RCS here, we noticed we got some - about a 5 psi or so change in the ASCENT OX and FUEL tank pressures - an increase, okay? We noticed that shortly thereafter. And what we'd like to do is to make sure they've got the ASCENT FEED VALVEs actually seated in the closed position. And when they get time, it'll - close two circuit breakers and cycle the switches for us to the closed position to make sure they are closed.
585634Would you write down the procedure and -
585640They're talking about display circuit breakers right now. We'll let that get settled.
585645They're having to go up and look up some data books, but how about stowage-wise, FLIGHT? Do we have to worry about passing some gear back and forth? Maybe FAO ought to think about that.
585658Bob? FAO? You got people working on that?
585701Say again, FLIGHT. Working on what?
585703Stowage - what might want to get passed to the LM? Or from the LM to the CSM?
585813Okay, I have this abort PAD, and I've got some gimbal trim angles. Pitch and roll are - are these the ones that were preset, or are we going to have to jimmy these around?
585823The preset ones probably were from docked. But let me check. RETRO?
585836These LM DPS trims, are they different than the ones in the vehicle right now?
585841That's affirm. This is based on -
585844And the ones they have on board are undocked, right?
585848FLIGHT, CONTROL. We've got some updates on those trims.
585850Oh. Okay. Well, come on in with them.
585854Okay, I can give them to you right now.
585856This is a coordination problem on these gimbal angles and I guess we're going to have to think of a procedure to coordinate the setting of those angles.
585909CAPCOM, you talking to me? I don't know what you mean -
585915Okay, they can't - they can't read them out on board - set them on board. They have to run them and then have us verify down on the ground. Right?
585925Yeah, well we can watch them trim it. I'm not sure I know what you're asking me, Jack.
585930We're going to have to, say - tweak it a little more and then we're going to have to, say -
585934No, they can trim it automatically, then load it. And run it through the program.
585938But we have to verify because there's a different time that -
585940Oh yeah. Yeah, we can verify the number.
585943And we're getting some new ones, so hold up on those - GUIDANCE, you calling me?
585946Roger. The middle gimbal angle's getting big, FLIGHT.
585951CAPCOM, have him watch his gimbal angle.
585954Okay, I think I hear him doing that. What do you want him to do, just -
585957Well, in case he hadn't noticed, it's getting close.
590120Could I get the people in the room to be quiet?
590134Standby, CAPCOM. Hey TELMU, he's talking.
590138We have any on panel 16?
590256Hope you've got somebody working on a PTC procedure.
590259Right. We have one already worked out, but it's an AGS-type procedure, FLIGHT.
590306I say that, I'm not sure if I mean that - but okay.
590315The CAPCOM read up the circuit breakers to open on panel 11; I don't believe he turned the page over. There's some on Panel 16 also.
590324Just a minute, TELMU. RETRO and CONTROL, FLIGHT. The COAS angles you have N/A, are they not - are they not available?
590335What does this N/A mean? For the COAS?
590339GUIDO said it was not available.
590343What do you mean, not available?
590344Not - not applicable. He said not available.
590350You might talk with GUIDO if you want more verification on that.
590400Don't you want to add a COAS star to this PC+2? The CAPCOM asked why not.
- Perhaps he did so off-loop.
590412FLIGHT, we'd have to know which axis that thing's mounted along right now.
590416Okay. You don't have enough data to figure that out, is that right, right now?
590420Well, I don't know if he's got it mounted along the Z-axis or the X-axis, FLIGHT.
590423Okay. That's what I'm saying. Okay.
590432TELMU, write down what you want us to do, please, on the circuit breaker - I didn't hear you last time.
590438The CAPCOM only read one side of that circuit breaker opening - we gave him a sheet, there's circuit breakers on panel 11 and 16 to open.
590448He only read up one side.
590449He only read up panel 11?
590453We can go ahead and compute one for along the Z-axis and if it's not mounted there he can move it and mount the COAS over on the Z-axis.
590553CONTROL, FLIGHT. You copying that?
590556Just caught the tail end of it.
590558Do you see any venting anywhere?
590602Negative. We've got a lot of drops in and out of data.
590607Okay. He's having some difficulty with it, so look for reasons why.
590630It's 133 hours. To the AOL, to the Atlantic.
- In the end, it would be closer to 143 hours.
590635You might let them know we're copying the VOX, too, Jack.
590733We have a load, FLIGHT, but INCO says we can't COMMAND.
590739We can COMMAND if we go to LOW BIT RATE.
590742Let's give them the numbers, then they'll punch in, Jack.
590745Let's just give them the numbers to punch in.
590747We'll read it up to him, FLIGHT.
590840Okay, I've got this list of stuff here for this ascent feed.
590843Okay. Bring it over please. Have somebody hand it on.
590851And FLIGHT, did we come up with something with regards to his - uplinking a time?
590857We'll have trouble uplinking the time. We'd have to go to LOW BIT RATE - can he easily punch it in the DSKY there, GUIDANCE?
590904Okay, stand by on that. We're trying an uplink mode that might give us COMMAND -
- and VOICE and HIGH BIT RATE.
590911For your information, the problem is that we've had to deviate some of the frequencies because of the proximity of the IU frequency, and that thing's still alive. Copy?
590921And that's - so it's a little bit nonstandard in that regard.
590926But they're seeing what they can do. Why don't you give them a GET hack, though, eh? And let them know we're reading that VOX.
590942Roger. We're on a COMMAND UPLINK mode along with VOICE, and we've got HIGH BIT RATE data.
590946Okay. P00 and DATA and we can give him a time - wait a minute. GUIDANCE, you ready to give them a time?
590950Roger, FLIGHT. We've got the LOAD.
590955We're ready to go, Jack.
591001He's got his UPDATA LINK OFF.
591024FLIGHT, GUIDANCE. We've got the LOAD to go ahead and do it now.
591027Yeah, I know. We've got another problem. Go ahead, INCO.
591029I think it would be better if we go to FORWARD OMNI on the LM now. This uplink.
591054CAPCOM, you need to - going to need to get FORWARD OMNI in the LM.
591059I believe he's already done it, FLIGHT.
591101Okay. Oh, it's already done. Hm. Okay.
591104Okay, and he's going to write a mission time into the LGC.
591114Can you do this when you don't have a DSKY? Time?
591127That'll give him his clock, will it, RETRO?
591134Okay, if he wants to turn his inverters off, we can monitor his middle gimbal angle here for him. One other suggestion I have is that he -
591140Wait, wait a minute. Let me - let me hear the COMM, here.
591244FLIGHT, RETRO. They've got a good clock update.
591255When we get a chance here, we'd like to take and change our offset on the two vehicles, on how we're getting telemetry, to try to solve this tracking problem. To do that we're going to have to drop the LM uplink and break lock for maybe 5 to 10, 20 seconds, there.
- INCO and his team want to move the S-IVB IU frequency below the LM frequency to solve the tracking problem. The frequencies could be changed by dragging them with a emitted signal from the ground once the link was locked in. But if the signals dragged across each other, both vehicles would snap together and become inseparable. Because the S-IVB link couldn't be restarted remotely, the LM would have to discontinue their link while the other signal passed through its range.
591309Okay. Well, let's just standby on that a minute.
591316Okay. Now, before we get into that one -
591327We'd like to have a VERB 74 some time when they can skip the DSKY.
591330Okay, GUIDANCE. CAPCOM, we're ready for an E-MEMORY dump. They'll give us a VERB 74, that's what you're talking about, isn't it, GUIDANCE?
591338We're getting an E-MEMORY dump.
591349CONTROL, FLIGHT. You saw an increase in the ascent tanks, is that right? Pressure?
591353And you want to be sure, what, that the ascent feeds are closed -
591356Yeah. Close those breakers and cycle those valves closed. Do not cycle to the open position, just to the close position.
591403- when he pressurized the -
591403Yeah, RCS. And we want to do an E-MEMORY dump whenever they can get around to it, we're all ready to receive it.
591410Okay, I've got one item, FLIGHT.
591413This is CONTROL. We want to power down his inverters -
- and in order to do that, we're going to have to look at his middle gimbal angle for him on the ground. And to make it easier, he needs to get out of this MIN IMPULSE mode. He needs to go to - PGNS MODE CONTROL to AUTO when he gets to an attitude that he likes.
591436But now, wait a minute. Before we do any of that, I want to hear what it is control configuration we're going to be in, and whether we can keep the PGNS up or whether we're going to bring the AGS up, etc.
591449I want to get the holes dug before we start doing more things to this.
591454Let me see if - have you heard that one of the suggestions is to align the AGS to the PGNS, power the PGNS down, use the AGS, and then bring the PGNS back up and do a P52 for the burn?
- The AGS was limited but sufficient for maintaining the platform and generated less heat (and thus used less coolant) than the PGNS.
591508Okay. Well, I'd like to get that whole complex of control modes and what we're going to do in currents sorted out before we do start changing things.
591516Or we'll be doing this all night. Okay, Hal?
591520And I'm open to any suggestions here as to what the reasonable course of action - the last I heard from -
591528- staff is that they're going to try to run that again in the simulator, I believe.
591622Roger, we're going to have to write a RESTART. 10 second loss of data.
591625Okay, everybody. Stand by for 10 second loss of data.
591703- yeah. CONTROL, FLIGHT.
591710Hal, Tom Stafford's coming over. Would you chat with him about this thing?
591719We got a good E-MOD, FLIGHT.
591720Okay, CAPCOM. We got a good E-MOD. Do they need to terminate anything, GUIDANCE, or does it terminate?
591814And that's the Atlantic, too, Jack, for their info. That's the Atlantic.
591833Yeah - we haven't made our mind we want to go there, but that's the PAD - that's the abort data he has in board.
591844It's the minimum return.
591858We'd like to send him a REFSMMAT sometime, FLIGHT. If he gives P00 and ACCEPT.
591904It's the one that they're aligned to. They were carrying one pre - prelaunch, and it's not the one that they're aligned to right now. We're going to give them the right matrix.
591915Okay, and then what does he do? Align to it?
591917No, no. He's fine. We just need to get it in there.
591921Oh, so he has it on board?
591925Okay. Okay, CAPCOM - are you ready to do that now?
591928Do you want to send them a state vector, too, by the way?
591930Negative, FLIGHT. We want to hold off on that.
591932I'm not sure what the LM will do with it. We're having MIT run the hybrid, and see what it would do with this kind of -
591937Oh, that's right, because it doesn't navigate out here.
591939That's right. So, we're having them run it on the hybrid, and check it out -
591942The REFSMMAT - I'm not - GUIDANCE, say one more time why you want them to have a REFSMMAT, because he doesn't have one -
591948He doesn't have the one he's aligned to right now, FLIGHT -
- he aligned to the PTC and he was carrying another one.
591955Yeah. We want him to have the one he's aligned to.
591957And we're also going to stick a T-ephem in, FLIGHT.
592003Alright, you want P00 and DATA now? You ready to go?
592004That's affirm. We're ready.
592033Roger, FLIGHT. We're picking up.
592053Can we try that procedure now?
592058Just a minute, Ed. Let me see what else is cooking, I don't have any -
- reason why not to. Go ahead, GUIDANCE.
592103We don't have the DUA. He gave us P00, but he didn't give us the DUA.
592109Okay, we need the DATA position, right?
592116We got Program 00 but he needs to go to DATA first to get the load in.
592129Okay. We're loading the REFSMMAT -
592138That's probably what it is, FLIGHT.
592152We're picking up, FLIGHT.
592157Okay. We're loading the REFSMMAT. We've got the VERB 74. CONTROL, FLIGHT, did you see him cycle the valves on the ascent feed?
592206Did he cycle the valves on the ascent feed? Jack says he did it.
592209Okay, we can't see that he did it, FLIGHT, on TM.
592214Okay. He cycled the ascent feeds - -
592221Okay, now, we're working on what we're going to do with the configuration. We need to get some kind of PTC going for us here, and we need to decide what we want to do with our control configuration - you're working all that, huh, CONTROL?
592232Trying my best to, FLIGHT.
592236FLIGHT, INCO. We're coming up on AFT OMNI for the LM.
592239Do you want us to switch now?
592241We're right in the middle of a load.
592242Okay, we'll - hold as long as we can.
592247He got it pretty quick on there anyway.
592740We're through COMMANDing to the LM.
592742Through COMMANDing, CAPCOM.
592748I'd like to go ahead and get that DUA off the line.
592750Okay. We're through COMMANDing, CAPCOM, and they can take that circuit breaker - the DUA circuit breaker out again.
592758We'd like to get as much gear off here as we can. We'd like for you to think about turning this inverter off.
592805Again, here? Which inverter?
592807The LM inverter. Inverter 2.
592809It's running the eight-ball. Yeah, I need to tie that together with how we're going to fly this thing, Merlin - I'm waiting to get this whole thing.
592818I understand what you're saying.
592820How many amps are we taking with that?
592822Well, we're pulling about 2 amps.
592826Well, I know. I agree with you.
592832The water rate right now, we're pulling about 7 pounds per hour. And at current capabilities, about 34 hours. Descent water.
592842About 34 hours on the descent water at the present rate.
592852Oh, okay. Okay, but we should be able to take the PGNS and and the IMU off -
592910Okay. I'd like to get everybody up here a minute. RETRO, GUIDANCE, CONTROL, TELMU, GNC and EECOM, and CAPCOM. INCO and FAO. Is everybody on the loop, give me an amber, please.
- Each controller had a little status light they could toggle at request; these were used for go/no go callouts, for example.
592929GUIDANCE, get a RETRO up in the loop, will you please?
592932Look. As I see it, we've got a number of things to do. No big hurry right now. We've gotta maintain COMM here, of course, with the LM. But we need to see what we need to do about setting up a PTC attitude and an arrange - a control mode. And what that means relative to the AGS and the PGNS configuration as to powering the AGS down, etc. Now, CONTROL, you're working that problem, right?
593003And I'm proceeding now just staying put until we get that whole story put together - and how long is it going to take you, do you think, to come to some conclusion on that, Hal?
593012I don't have an estimate right now, FLIGHT. We're trying to get it to you as soon as -
593017Alright. Now, so - so we'll just standby on that. We are interested, though, in this also from the point of view of the power configuration. TELMU, I assume you're working out all the consumable options, and as soon as CONTROL's got a mode here you're going to be able to lay out a power profile to tell us where we stand on all your Oâ‚‚, and your water, and your power, right?
593042But can you say something generally, now? Generally, we can come all the way home at 25 amps, right? On the LM?
593050Not with this water usage right now, FLIGHT.
- Again, water/glycol coolant.
593053No, but if we go down to 25 amps all of that will help us, won't it?
593058Oh, I see what you're saying. 25 amps - not much.
593100Yeah, that's not going to help us that much, FLIGHT.
593103Okay. Well, what do we have to get down to? For example?
593110Standby - I would think about 15 amps or so.
593112From the point of view of the water then we've got to get down that low -
593114Yeah. About 15, I think.
593117Can we do that? In a life support/COMM mode?
593121We could be at 15 amps in a life support/COMM mode, could we not?
593125Alright. Now, we need to figure out something also for your COâ‚‚ scrubbing, right?
593130And - and EECOM needs to know how he's going to do that over in his vehicle if we have to get into that. I've got a note up here that I don't quite understand, it says LM LiOH is 48 man-hours. That doesn't sound quite right to me.
593145That's on the cartridge - standby, we'll get you consumables.
593150Alright. But TELMU, I'd like some people to start running consumable profiles out, making a couple of different assumptions and not standing by, waiting for everything - and please have somebody run it out grossly, you know, so that we continue to have at least a story even though it's not the most accurate one; you can continue to refine it as you go along.
593209I'd like to relatively soon here get some idea how we stand and what we're - boxes we're running into and when we've got to start deciding things, okay?
593219Okay, does anybody have anything else besides those areas that they want to bring to our attention right now?
593228If we can get that change done, where we get some tracking data for FDO, we'd hope. If you'll let us drop the uplink and the downlink from the LM for about 25 seconds.
593237And then re-establish it?
593241We'd like you to alert the crew that they're not going to have contact for a few seconds.
593244Okay. Let me go around, Ed, and then we'll pick that up. Does anybody have anything else? Let me go around the room. Trench - RETRO? FDO? GUIDANCE?
593254GUIDANCE, you okay? Well, go back green then, please. CONTROL, you got anything else?
593303Okay. I want to start hearing from you, TELMU, on these consumables.
593306I want to start hearing from you as you get some -
593310Okay, go back green, then. GNC?
593314Green, please. CAPCOM, Jack, can you think of anything we ought to be working on other than those mentioned?
593320I didn't get all you mentioned, but are we working on bringing the AGS up?
593324Yeah, that's a possibility, you know? As to whether we gotta do that for the PTC, and do what Tom suggested here.
593332Well, we could bring it up and have it there, and it'd be a good idea to make sure it's working.
593337Yeah. I just don't want to use any more power right now, or any more water.
593343As soon as we know a little more about what we really ought to do, then we'll proceed to spend the consumables to do that. Anything else that you can think of?
593352I'd like to have a little more information upon the crew's trajectory with relation to the Moon that we could pass up.
593359Yes, and INCO is gonna - at the end of this go-around the room, we're going to ask the crew to standby for about 25 seconds of COMM loss while we do some reconfiguring in an attempt to get tracking on the LM. Okay? But we still think they're still close - FDO, FLIGHT? What -
593418What closest approach are you estimating right now on the LM?
593422Still looking at about 60 miles, FLIGHT.
593423You're still looking at 60, Jack.
593428And this COMM thing we're going through is to try to re-establish tracking on the LM; right now, we don't have tracking.
593436You can go back green, then, if you will. Okay - SURGEON, you have anything?
593439Yeah, two things. We're figuring, looking at this COâ‚‚ problem with you - at what point in time we'd arrive at various levels of COâ‚‚ in the LM configuration. The other thing is, Glynn, we - at some point in time we'd like to get that BIOMED switch on in the LM - it's in the OFF position.
593500Okay. Okay, you want to go back green, then? INCO, anything besides that COMM -
593511INCO, anything else? Go back green, then. AFD?
593516FAO, you have anything you're working on - that's stowage, right?
593519That's affirmative, FLIGHT.
593520Any suggestions we might have as to what they might move to the LM, or move to the CSM.
593524That's right. We're working on that. I think it'll be minimal anyway.
593528Okay. And NETWORK, you got anything?
593531Well, we hope to have Honeysuckle 210 up by 62 hours for voice only.
- Honeysuckle's big dish was being used for another experiment and had to be repurposed on very short notice for the rescue effort.
593537We hope to have them up by then.
593539Okay. RECOVERY? You got anything?
593542Negative, FLIGHT. Present efforts are to identify ships on the Atlantic and the Indian Ocean.
593546Okay. NETWORK, you want to go back green, then? Okay, there are the subjects, and we need to start getting some - closed out on some of them here, gentlemen. So. Let us bend our efforts to get that done.
593605Yeah. CAPCOM, would you call the crew and tell them we're going to drop COMM for half a minute here while we try to establish tracking?
593613And let them know that our best estimate of the EC's got a 60 mile perigee right now.
- Technically, pericynthion. Perigee refers to Earth.
593618And FLIGHT, if you'll confirm AFT OMNI.
593700Okay, INCO. We've told them. Go ahead.
593949<< An off-loop conversation is partially caught here, which appears to pertain to powering some elements of the CSM off the LM, possibly to use its life support system. Additional conversation discusses a burn - possibly the one that occurs in the final chapter of this audio to bring the crew back onto a free-return trajectory to Earth as soon as possible, rather than waiting until PC+2 at 79 hours. >>
594139That sounds okay here, FLIGHT.
594147We agree with all of that.
594157As a matter of fact, Jack, why don't you let them know that we're currently - since it's so quiet from here - trying to figure out what's the best configuration to do here relative to maintaining control, maintaining some kind of PTC, staying in the posture that we can do the burn properly, and playing that against the consumables. And as soon as we get a reasonably coherent story we'll brief them in full on it. Okay?
594224Okay. How about - are we getting a flight plan worked out, modified, so forth?
594231We are working on that, FLIGHT.
594232Yeah, working on it. And you might also tell them that we've got Gene Cernan and the guys over in the simulator checking stars, etc, in this configuration.
- Gemini veteran, Apollo 10 LMP, and eventual Apollo 17 commander.
594243And anything that they would like us to run, we can proceed to do it.
594303TELMU, let me hear the COMM. Okay? Can we hear it? Do you need something?
594308We've got to power down, here, pretty quick.
594314We ought to - recommend turning the power off - POWER AMPL off, going to LOW BIT RATE, and getting his AC off, and probably bringing the AGS up on standby.
- Alternating current inverters
594330Okay. What consumable are you running into trouble with, TELMU?
594333Water and electric power.
594337Okay. Can you relate some facts to me, here?
594342Like I said, the water is - present rate, we've only got 34 hours left.
- With splashdown predicted for 133 hours, they would come up nearly 40 hours short here at the present rate of usage.
594417Okay, the power is 67.5 hours, FLIGHT.
594421Is that ascent and descent?
594423At the present load, is that right?.
594430That's what I - I think we just need to get some things powered down ASAP.
594434Okay. Now what are you suggesting, again?
594436I'm suggesting POWER AMPL -
594438POWER AMPL. How much does that save?
- and LOW BIT RATE - that's about 2.5 amps.
594446And the AC, which is about 2 amps.
594448Well, that loses his ball; then we don't have anything. Right? I mean, we don't have the data on the ground - do you have IMU data on the LOW BIT RATE there, CONTROL?
594458All we'd have is resolvers. It's good enough.
594502Yeah, we can watch the gimbal angle.
594503What control mode is he in now?
594505He's in PGNS MIN IMPULSE.
594506So he's still flying it around.
594513I think it's kind of difficult to talk them through, isn't it?
- What FLIGHT is referring to here is: say the spacecraft is nearing gimbal lock. How do you describe the direction to rotate toward to avoid it?
594520He'd have to bring the ball up to fly it, I'd think.
594523Well, my thought on that a while ago, FLIGHT, was if he goes to an ATTITUDE HOLD mode now, and out of this drifting flight mode, he'll hold the attitude he's in now.
594528Okay, then you don't have to worry about it.
594530Was that what you want to start - recommend, and EECO - TELMU's getting in a hurry, here.
594536Yeah, well, I don't blame him.
594537What's going on with the COMMs, FLIGHT?
594547What else, TELMU, have you got anything else to suggest?
594554Now, how about you? What can you do to help? What do we need to do to decide whether to go to the AGS or not, here?
594604Do we know whether or not the - results of this star business in the simulator worked?
594608That was a request I've got in to SPAN, to extrapolate the measured drift rates on this particular platform to see what it would look like when we got out to 79.5 hours.
594619Okay. But if we can see stars, we can do a P52.
594622Yes, if he can see the stars, then that kind of falls out, you know? And if that - if he can do a 52 align we'd definitely recommend to transfer the alignment into the AGS and turn the AGS on, turn the PGNS down.
594635What are you getting out of the star sighting discussions?
594639Well, the last thing I heard was that the sunlight reflected off the thrusters - made it so as they couldn't see the stars and they also had a lot of debris still floating around with them, so they are unable to -
594649Couldn't see them out of what? Out of the window? Or out of the AOT?
594654Have they tried the AOT yet, do you know? The reason I'm asking is that we're running low on water. I mean, we're going to run out of water in 34 hours at the current power level.
594734How about going to LOW BIT RATE? The POWER AMPL OFF and the LOW BIT RATE? CONTROL? Can you do that now?
594739GUIDANCE, can you do that now?
594747Okay with you if we turn the POWER AMPL OFF and go to LOW BIT RATE?
594751Well, why don't you let us get ourselves swung in, here, and see how we're going to work out with this problem? We're -
- in the midst of that procedure, there.
594756Oh, okay. You're still in the middle of that.
594800I don't have any COMM with them, FLIGHT.
594804INCO, FLIGHT. Do we have no uplink right now?
594809How come? We still - I thought that was only going to take 30 seconds.
- Of course, 30 seconds would be if all went well. It didn't, and the LM and IU frequencies got accidentally locked together. It would take quite some time to get a narrower-beam antenna to target just the IU and control its frequency separately.
594840FLIGHT, INCO. I don't think he's got an uplink COMM mode right now.
594844Yeah, he's coming through right in that spot that I told you about, there. We're trying to force that lock now, and as soon as we get it we'll give you a call.
594852Are we tracking them yet, FLIGHT?
594854For reference, going to POWER AMPL OFF on an OMNI in LOW BIT RATE -
594857Wait a minute, wait a minute, Ed. The CAPCOM wants to know when we're going to have COMM. Is it coming back shortly?
594903I'll give you a call. It'll be back shortly.
594905Alright. Okay, now the POWER AMPL.
594907If we turn the POWER AMPL OFF, go to LOW BIT RATE and stay on an OMNI, if we go to DOWN VOICE BACKUP; we may be able to make it. It'll be very close.
594923It's going to be marginal.
594930I'd like to give it a try, though.
594933Okay, well let's finish up your test. Are you finished with that test?
594935No, they're not quite finished yet. Standby.
595014Merlin, I've got your problem, and I appreciate your concern. Right now we're trying to get the COMM back - we kind of have to get his assessment of this thing to see whether we can bring the PGNS down now.
595026Okay. What about the AC? Did - you still kicking that around?
595030Well, that's a problem. I don't know what we're going to do for PTC yet. I'm waiting for CONTROL. Without the - we can't just sit there in ATTITUDE HOLD. And I don't know about setting up a PTC in the LM.
595056Are his attitudes moving around some? Or is he essentially fixed?
595101Essentially static in attitude.
595105He's moving just a little bit but not a heck of a lot.
595141This ASCENT TANK 2 pressure has gone back down to a nominal value. We'd like to go back to the DESCENT Oâ‚‚.
595148Close TANK 2 and open DESCENT TANK.
595151Okay. CAP - INCO, are we anywhere near back in COMM yet?
595156FLIGHT, if you just hang on a couple of more seconds here, maybe we can get this thing squared away so we get the tracking data that the FDO needs. That's what we're after, here.
595205No, we're not - we don't have a good COMM mode at this time.
595209CAPCOM, when you get COMM back, we can go back to DESCENT Oâ‚‚. You got that, Jack?
595234Is it the same procedure?
595253GNC and CONTROL, FLIGHT.
595257Is somebody working me out a PTC procedure?
595300Yeah, we're trying to get pulled together. We've got one for the AGS right now, FLIGHT.
595328It looks like we're getting it slowly, here. We're just about there. As soon as you get it, we'd like to go to FORWARD OMNI.
595413Merlin, how many amps are we using with the LGC and the IMU?
595427Total. So we still have about 20 amps, huh?
595432But they're the - they would be the big coolant items, wouldn't they?
595435That ought to improve the coolant picture a heck of a lot more than 30 percent.
595542That's a negative, FLIGHT. There's no uplink.
595546INCO, have I got an estimate?
595549FLIGHT, let me tell you what's happened. While we were trying to lock it up, we've drifted around into FORWARD OMNI country. So right now we're in FORWARD OMNI, we've got AFT selected, and he doesn't know because -
- he has his display breaker pulled. So if I can bear on your indulgence to wait until we swing all the way around to the AFT OMNI, then we can get this -
595606We're not exactly swinging, you know?
595608Are we? We moving around?
595611Like this? As far as you can -
- Sadly, the loops do not record hand gestures.
595618Roll. LM Yaw.
- The CM and the LM had different axis labels, as the CM flew "forward" with its nose, while the LM axes were optimized for the crew's vantage point while landing on the Moon.
595631Yeah, okay, well - I don't know how to read that one. Is that roll?
595637FLIGHT, we are pitching right now.
595643Well, wait a minute. You guys have data? We should - should we be able to get through then, on the COMM?
595648CAPCOM, you should - INCO, do you think we've got COMM now?
595651Give it a try, and get him to say FORWARD OMNI if he shows anything.
595736CAPCOM, as soon as you get a hold of him, would you get him to say what he wants to say about the starfield? And you can tell him to go back to the DESCENT Oâ‚‚. CONTROL, from FLIGHT.
595747I'm becoming convinced that we don't have any choice here, but that we've got to go to some kind of AGS mode, here.
595752That's right; I'm taking the procedure now.
595753Okay. You getting it all written up?
595755I'm getting it - priority out of the Activation checklist.
595807The - procedure - procedure is available from these - from CONTROL for the AGS PTC, and I think we're running out of choices. We're probably just going to have to -
595818CAPCOM, you might try it now.
595900CAPCOM, have you - have you got them yet?
595905No, I haven't got them yet.
595907There he is. Okay, everybody. Here's COMM.
595923It's probably due to our configuration.
595936And we need FORWARD OMNI.
600013He's been on it, and he is on FORWARD OMNI, and the COMM has a lot of background noise from Houston.
600018Okay. What can we do, INCO?
600020Okay, let me just try one more thing, we'll be with you.
600034Look. When we get them, you get the Oâ‚‚ business straightened out. But tell them that we have to, very soon, decide to bring the AGS up, and do things with that.
600120INCO, FLIGHT. What are we getting?
600153INCO, FLIGHT. Are we going to get COMM back? I'm going to knock off the tracking here in a minute. That 30 second -
600156That's - FLIGHT, we're going -
600159Right. We're going back to the normal mode. Standby.
600247CAPCOM, does he have anything to say about stars and P52 yet?
600255No, I haven't heard any word. I can't ask him a question because he can't read me.
600258Yeah. INCO, have we reconfigured yet?
600313No estimate. I'll get it for you soon as we can.
600331FLIGHT, we have a 2 minute estimate.
600442It was the ground configuration.
600531FLIGHT, INCO. We need AFT OMNI.
600604If he wants to try the method John's been talking about, we can give them an attitude to go to.
600614FLIGHT, that's the IU frequency. Just say AFT OMNI and we'll be in there, I think.
600631CONTROL, FLIGHT. How are you doing?
600633We're just about there, FLIGHT, on this AGS turn-on procedure.
600639Can we go ahead and get the POWER AMPL off?
600643I'm afraid to do anything to the COMM right now, until we have this discussion with them about what we want them to do, Merlin.
600655- I sure do. And I want to get it off as bad as you do.
600736Is there much of a difference to you to operate on the AGS, with the PGNS down? Water-wise?
600741Still want FORWARD OMNI?
600742Well, it's about - about 3 amps, but primarily the AGS does run a little cooler, and you'd be bringing up a new piece of gear. So, it'd be a different thermal load, there.
- That hasn't been running and is therefore starting cold.
600753Yeah. Well, I want to get into this configuration and try it.
600757Has he said anything about the stars yet? Jack?
600800No, he hasn't. We can't even ask him a good question. You still want FORWARD OMNI?
600810But you're not going to get through.
600815They're having trouble grabbing ahold of the S-IVB to push it out of the way, is what the problem is.
- Somewhere in their frequency tuning, they managed to get both spacecraft tangled together. Unfortunately, the fallback frequencies both craft default to when a link can't be established are also very close to each other. So the only way to separate them is to use a dish precise enough to physically target just one with its beam -
600820Okay, well, we had COMM before. Can we get back to there?
600822That's what they're trying to do. We're not having any luck. There's one suggestion we can do. We can turn the LM transceiver completely off for about 2 to 3 minutes, and let them grab ahold of the S-IVB, push it out of the way, and then bring it back up.
- FLIGHT must be wary of these time estimates by now.
- - or, to turn the LM COMM completely off and talk just to the S-IVB to move it aside on the frequency band.
600838Is that what we have to do now? We can't talk to them to tell them to do that.
600840Well. That's right. But if we can get up ?? here, just say: "turn your transceiver off for 3 minutes. Then turn it back on." And I'll try to give you a call if I think you can get through.
600914What's the proper terminology over there? On the switch.
600917You want the TRANSMITTER/RECEIVER?
600917TRANSMITTER/RECEIVER to OFF. Panel 12.
600928You want S-BAND XMTR/RCVR OFF?
600931Is that our best step here, INCO?
600933INCO, FLIGHT. Is that our best step to get COMM back?
600943Is that our best step now to get COMM back?
600945That's our best step. Right.
600947CAPCOM, give them that. We'll try.
600948He's not going to hear you, FLIGHT, right now.
601010Now, how close are you to having this thing - you're proposing an AGS PTC mode and a -
601016Well, we just got input - what I'm going to do you - with right now, is a procedure for turning the AGS on and aligning it to the PGNS, so we can turn the PGNS off.
601024And that'll leave us in an AGS ATTITUDE HOLD mode.
601027And I just got word from SPAN, the procedure we had for the PTC in AGS, Carlton Hanaway has been, he's - it's not going to work. He's working feverishly to get one that will. Just got that input.
601040You might be able to handle it without the PTC, save the attitude that we at - are now at, and then just change attitudes over some time schedule.
- This ended up being the approach, after the end of this audio record.
601051Do you recommend we simulate this procedure over in the LMS before we ship it up?
601057Which procedure, Jack? What we're proposing is an AGS ATTITUDE HOLD that we change periodically.
601105Since they don't have a PTC, as such, that works.
601108Well, that's what I mean -
- we've got a procedure that will give us PTC in AGS, try it in the simulator first.
601114They - they don't have a procedure to get a PTC in AGS. They had one -
- but it doesn't work. Somebody thinks it won't, so we're not going to try it. Unless you want to try that one in the simulator.
601253INCO, sing out as soon as you think we've got COMM over there, will you please?
601300They're trying to bring up an uplink carrier to the LM so we can get some voice to them.
601334I'll bring you up to speed on what I've been doing down here.
601336I'll bring you up to speed on what I've been doing down here. Looking at a maneuver in the vicini - in the present time range, and on the vector that I've got now, looking at about 16 feet per second to get free-return.
- What FDO is talking about here is the plan to be shortly executed. Rather than wait all the way around the Moon to 79 hours (PC+2) to get the spacecraft back on track to return to Earth, they will initiate a burn with a ∆V of 16fps (11mph; 17.5km/h) very soon, after which they can power down the PGNS and feel good about being roughly on track.
601349Yeah; that's what I'm hearing over here in my other ear, Bill.
601351Alright. And, I've got some selects down here working on a vector right now. This is on the CSM doppler after the glitches.
601359And we're not sure whether it's going to be any better than what we've got now.
601404So, I guess what I've got to say is that in about 10 minutes, I can have a maneuver ready - I'll be able to compute a maneuver; time range of 61:30. And we can make our decision with that - ∆V will be around, like I said, about 16 or 17 feet per second.
601420And that's a free-return.
601421That's affirm. So you can work with that number.
601429Okay, we've got a good G&N now, if we - probably get a real good burn off now. Go ahead and do it with this good G&N -
601600Can we - how long would it take you to get a free-return maneuver - could you get one at 61 hours?
- Lunney is anxious to get the PGNS off.
601607Roger that. I can. It's just a question of which vector we want to do it on, FLIGHT.
- Whether to use the current guess of the spacecraft position, or to wait for tracking data which may give a better idea.
601611Well, get one at 61 on the best vector you have.
601714EECOM, FLIGHT - TELMU, FLIGHT.
601717Merlin, how much water does it cost us to keep the PGNS up for another hour?
601723You got an hourly rate on it?
601814FLIGHT, I think you've got COMM.
601836That's about - cost you about 3 pounds of water.
6018393 pounds of water to keep it up for another hour.
601846That's - seems to me to be worth it.
601848Yeah, right, I think we gotta keep it up.
601850Get into free return and then power it down -
601851Yup. Then power it down, let it drift, and we'll do what we want to tomorrow.
601855Okay, but can we go ahead and turn the POWER AMPL off?
601859POWER AMPL. What will that do to my COMM?
601902We lost it again. Standby.
- Lunney loses his cool a bit off loop here.
601907Gentlemen, we're going to proceed to do a free-return maneuver here. At 61 hours, assume that; as soon as we get COMM with the crew we'll see how they feel about doing it there. It's going to be about 16 feet a second, Jack. We want to get on a free-return so we can get powered down. And we'll still kick it at PC+2, if - all - if we can get everything back up and aligned properly. But, with the way it is, we want to get back on free-return; cost us an hour's time here with the PGNS powered up, that's 3 pounds of water and we'll spend that. Okay?
- Speed up the return with another burn.
601941Now, FDO, get me a PAD, pronto.
601945And we'll run a couple of them in case we get behind on time, here. GUIDANCE, what do we need - how do we need to burn this thing? We don't have a vector in there; it's not going to be a guided burn, is it?
- The LM's computer, despite having identical hardware, was not set up in software to perform calculated maneuvers outside the Lunar reference frame.
601955FLIGHT, I'm going to MIT run it in a hybrid and see if it can take a vector, if it'll work alright -
601959If it can't, how do we do it?
- that's what I'm working on right now. If it can't, we'll do it in ATTITUDE HOLD. P47.
602004Alright. I think that's the way we want to do it anyway, that mode will get you all that -
602007Yeah, that's what we know will work right now, I think. But we're going to look at the other.
602026INCO, let me know as soon as we get COMM, will you?
602049INCO, what do you think my chances are getting COMM back here shortly are?
602055Starting to look a little better here, FLIGHT.
602057Okay. FDO, you got an estimate on that PAD?
602100You got an estimate on that PAD?
602106And while you're at it, and get - while you get that one out, run a couple more at 15 minute increments. Run one at 60:45, and run one at 61:15, etc. Okay?
602119But get the 61 hour one out pronto.
602124CONTROL, FLIGHT. You copying me?
602127We're going to do a little burn here, 16 feet a second and get back on free-return -
- as soon as we can get COMM, we're shooting for 61 hours.
602139GUIDANCE is doing something to see how the equations are going to work, but I'm inclined to say we ought to do it in ATT HOLD PGNS. Consider that, and consider everything else you want to think about and tell me any changes you'd want to make. And where we ought to pick up the checklist, etc; and let's refer to the - as best we can from the pilot's books, Hal. Tell them where to pick up from where they are now.
602243It looks like you've got it.
602244COMM, Jack. Okay, everybody, let's be quiet. We have COMM. We've got a lot of business to do.
602413No, I don't - wait a minute!
602414We can give them another 15 minutes if - yeah, we can give another - get a suggestion from him. We can figure it out whenever he wants it.
602424Get a suggested Tig time from him, Jack, that he's comfortable with. Yeah, it's not going to cost us much water.
602459FDO, stand by on a Tig time.
60250761:20. Is that okay? 61:25.
602533Okay, FDO. You got that Tig?
602539Go, FLIGHT. FLIGHT, FDO.
602547FDO, you got the Tig time?
602712Okay. CAPCOM, I don't think he ought to do any special maneuvering to find this out right now, do you? Don't talk them into that.
602739Okay. Let's concentrate on the burn.
602821I didn't hear all of his question. John?
602824How much can he use the TTCA?
602829FDO, FLIGHT. Have you got tracking on the LM?
602840That's affirm, FLIGHT.
- Good news: all the radio work was worthwhile.
602841Okay. Are you seeing anything? He's using his translation controller for attitude control. With the stack. You understand?
602848And now are you seeing that in the trajectory? Have you got a good, solid trajectory?
602900GNC, FLIGHT - CONTROL, FLIGHT.
602909Consider doing a 16 foot-a-second with the Command Module RCS. Service Module RCS - tell me what that means to me.
602918Okay, he's wanting us to follow him through on the 2-hour activation. And so I want some people -
- standing by to go with it on me.
602926CONTROL, TELMU, GUIDANCE. FLIGHT.
602928Stand by on the loop here -
- we're going to follow through the activation.
602931Okay, are we - down through 1. Step 1 on page 1.
602946I'd like you to ask him to manage the OMNIs as he's talking.
602950Does he have his meter up?
602952Yeah, it seems as though he still has that display breaker in, so the meter must be up.
602956It appears from my CAL curve that he's up.
602959Okay. Let's go. He's gotta hurry to get this 2-hour Activation done in 1 hour. So why don't we -
603004Okay, everybody. Quiet in the room, please, and let's walk through with Jack on the Activation. Everybody got their book out, ready to follow. CONTROL, TELMU, thumbs up -
603015Okay. We're on page 1, step 1. And he's going to be talking back.
603115Okay, we do not want to INVERTER 1 CLOSED.
603120We do not want INVERTER 1 breaker CLOSED in step 5, here.
603123Okay. CAPCOM, we do not want INVERTER 1 circuit breaker CLOSED in step 5. Do not.
603222FLIGHT, we recommend leaving the caution/warning off.
603225Caution - recommend that, huh? He says recommend leaving caution and warning off, Jack.
603312Okay, on step 1 did I understand he left the - that he did close ENGINE CONTROL breaker?
603320Did he activ - did he close the ENGINE CONTROL breaker under item 1, page 3? Last entry.
603338FLIGHT, INCO. We need AFT OMNI.
603353Can you wait a minute, RETRO?
603402That's not it, FLIGHT. That's not it.
603409And we need an AFT OMNI, Jack. We'll lose COMM.
603441Okay, you want the circuit breaker -
603513Okay. Have him standby right there, Jack. What is it, CONTROL?
603515Okay. On row 1, we need -
603521Circle it, we'll get it at the end.
603641Okay, standby, we have a comment. CONTROL, you have a comment.
603643Yes, on row 1, DECA GIMBAL under AC BUS A needs to be closed.
603649Hey, there's a lot of breakers that aren't closed that we have called out in the checklist here. Do you want them to close all those that are outlined?
603704We'll catch the DECA POWER later on.
603710We'll remind him of that later.
603713It'll come up in the procedure later, Jack.
603720How about the rest of these breakers? You want them to close them and open them as outlined in the checklist, here, or you going to have them hold up? Looks like we're going to screw up our procedure here if we don't do it just the way it's outlined.
- CAPCOM doesn't like the seat-of-the-pants verification that's happening.
603733I didn't hear you, Jack, I was getting other input.
603735They're really going to give you a lot of data you don't need - displays and stuff you're not going to get.
603748- they're supposed to be in that are not now in -
- aren't we going to call those out now?
603752TELMU and CONTROL, do you want these that aren't closed to be closed?
603806Negative from us, FLIGHT.
603807Well, why are you saying that? Why don't we just do it by the book?
603809Well - that's the quickest thing in my mind, to do it - just do it by the book.
603813Well, why aren't we doing that?
603816Well. It may take a little more power than what we need - than what we've got to spare.
603822Well, I'm willing to spend that right now.
603825Use the reviewed procedures? We want to -
603827Yeah. I think we'd better stick with what we know works.
603830- I think we ought to stick to the procedure as-written.
603832Yup. I agree, Jack. Let's go ahead.
603834You want me to tell them to push them in as -
- outlined on the checklist.
603838Yes. I don't want to take any chances with this.
603917Okay, everybody, stick with him now. We're going to be moving on to the next steps.
603924GUIDANCE, FLIGHT. I want you to have somebody looking ahead. We're going to do this burn in P47. Right?
603930FLIGHT, GUIDANCE, I don't think we can do it in 47. I don't think we have TVC control in 47.
603936What are we going to do it in?
603938We'll have to do it in 40.
603941It doesn't - do we know it works?
603943We're having MIT run it.
603945We have to get them a vector then, up. Do we?
- With the passive P47 burn program, the computer doesn't need to know much. But to do a P40 it would have to know its starting state vector so that it would know that it achieved the desired post-maneuver state vector.
603949I don't really care for that - that's all we can do?
603953Well, we haven't talked to CONTROL about using the AGS possibly.
603958The AGS's not up, and that's strictly a manual operation - that'd be even worse than a 47, probably.
604003The procedure as written calls for P40.
604006Yeah. The concern, Jack, is that the LM computer, with these funny vectors, we have to verify, see -
- Again, because the spacecraft is not in the reference frame of the Moon at the moment.
604027When will the answer come in if it's okay - when are you going to put a vector in, etc?
604036They're on schedule right now for 61:30?
604039Okay. We'll - roger. We've got a vector, I think now, that we could go ahead and - but let's standby to get - see if we could get an answer here in the next few minutes. It might be close to there on the hybrid right now.
604052Yeah, okay. When am I going to get the answer? Do they know I need it in - you know, 10 or 15 minutes?
604058We don't have all night.
604107Okay. And now we can go through this list and see if there are a couple odds and ends we can yank out. Like the tape recorders, he suggests.
604114Okay with the tape recorders, TELMU?
604119Anything else that's essentially trivial?
604121We'd recommend opening the RENDEZVOUS RADAR HEATER -
604125They're already opened.
- But the checklist wants them closed.
- and the LGC. LANDING - excuse me, LANDING RADAR.
604131All we've got, then, is the recorder, Jack. We agree with that. The others are all okay.
604217While you're doing that, could you have somebody work with GUIDANCE on - even without TVC, if we trim this gimbal up right, and don't throttle up for 40 feet a second, we ought to be able to have a pretty good controlled burn.
604234Work that problem in case thing from MIT comes out negative.
604237Okay. You talking about doing it in 47?
604244How about VHF A and B? We want that left off?
604318When we need it - when we want it we'll tell him.
604319Leave it OPEN; we'll call for it when we want it.
604425CAPCOM, FLIGHT, they're going back over the panel, are they? Okay.
604431CONTROL, TELMU, and GUIDANCE, and INCO.
604433Look ahead a little bit, now, in this thing, and anticipate what you want to be deleted.
604448Negative. Not - negative on the PQGS. Standby.
604451Negative on the PQGS. We're checking the REGs.
604502And negative on the ASCENT HELIUM REGs.
604504And how about the SYSTEM ENGINEER X-POINTER?
604537TELMU, you said no, didn't you?
604549FAO, let me how we're doing on time, will you? How are we doing?
604554Roger, FLIGHT, we will. Standby.
604557I want you to monitor us here, and see that we're on time.
604617We need the ATCA breaker, but no AGS.
604639It's for the gimbals, FLIGHT.
604647ATCA AGS? Is that what he said?
604650He's only reading out the ones he's leaving open, is that right?
604655That's affirmative. The ones that are black in the checklist, which he is deviating, he is calling out.
604701Yeah. Okay. I assume the other ones he didn't mention are closed, if they are blacked in.
604715You want that one closed?
604716Yeah. It doesn't pull any current.
604718CAPCOM, want that closed, it doesn't take any current.
604802Which circuit breaker is he talking about?
604804He said can we leave the steerable off, and operate off the OMNIs?
604807That's true. We want the heater circuit breaker left in, though.
604811Okay. Are you listening to the loop?
604813Yeah, we want the heater circuit breaker in, but we'll stick with the OMNIs.
604846Okay, we've got a - our LOAD's ready to go, here, FLIGHT. We want to load a vector and external ∆V.
- This is the current ground-based tracking information of spacecraft position and velocity.
- And this is the burn specification.
604851Okay. Have the loads been verified, yet? Is this the same vector that's being run on a hybrid?
604858Close to it, FLIGHT. Essentially the same thing.
604907And when they run it and say it's okay, we can assume it is? Is that right?
604911Alright. Is it the same vector we would have used for this DPS +2 - LI +2 hours, or is it a different one?
604919Well, it's FDO's present vector, FLIGHT. The only problem that we're worried about is the integration problem on board -
- The AGC read the IMU several times a second to update the state vector, thus integrating it over time. Once again, the abnormal reference frame is the concern.
604925And the scaling, and all that business.
604927Yeah, but the vector doesn't really matter all that much what vector it is.
604936This is - this is essentially the one. We need to load this, though. Even to do a P47 -
- we need to load this vector.
604948Say again, TELMU? Negative?
604954And, CAPCOM, if we get P00 and DATA, we will put a state vector and target LOAD in for him.
605020GUIDANCE, you should have it.
605022Okay, FLIGHT. We'll have to wait until they get the uplink configured. INCO's working on it.
605031Negative. You don't need it.
605043Before we burn here, we should deploy the landing gear so that we don't get any control problems.
605048Does that come up somewhere in the procedure?
605056I didn't hear his question, Jack.
605057ASCENT ECA breaker on panel 11, we want it OPEN or CLOSED?
605113Okay. Are we happy with the circuit breaker configuration? Do we want them to press on?
605116Circuit breaker panel. CONTROL, GO or NO GO?
605132What about the landing gear?
605134They'll come to that in the checklist, apparently.
605237FLIGHT, FAO. We concur with that.
605244INCO, do you have the OMNI for the burn attitude?
605246FLIGHT, GUIDANCE, we're in the middle of a LOAD right now.
605249Oh. Okay. CAP - what do you mean? You don't want them to maneuver?
605252That's right. Let's hold it.
605253CAPCOM, could he hold his maneuver until we finish the LOAD, please?
605314MIT recommendation for the maneuver to attitude is to use the TTCA rather than the auto-maneuver. Hand controller.
605322Okay. He's been doing that. We'll give it to him.
605531FLIGHT, we're through with the LOAD. They can maneuver.
605536And you want TTCAs, right? CONTROL? For the maneuver?
605544You want TTCAs for the maneuver, right?
605547To the burn attitude. That's affirm.
605623CAPCOM, FLIGHT. We're through with the LOADing. He can go ahead with his maneuver. We recommend he uses TTCA.
605631We recommend that, and we're through with the LOAD.
605647Okay. Everybody in the room, we're back on the checklist.
605656Are you with us now, on the checklist?
605658Do we want to do the self-test? GUIDANCE?
605703FLIGHT, we did check the E-MOD, his E-MEMORY was GO.
605706Do you want to do the self-test?
605714On the 2-hour Activation. Do you want to do the self-test?
605717FLIGHT, FAO, you'll get behind if you do it.
605718It's not - it's not required, FLIGHT.
605721Okay, let's go. Let's get in and -
605722Let's go. Let's listen to the loop, and answer their questions.
605724Answer up on the checklist.
605805Okay, everybody. We have - we're on page 9 now, right?
605807Yup. We scratched the VH - VHF. How about this LGC CMC clock sync T-ephems there, GUIDANCE?
605814We've already taken care of that, FLIGHT.
- they can pick up at the landing gear deploy at the bottom of 10.
605832Okay. Well, let's walk through it one piece at a time.
605840That's good, Spence, but I don't want to skip anything. Let's just let them go through it.
605843We need that landing gear out?
605851And we don't want the steerable.
605903CONTROL, you want that done, right?
605909Okay. Standby for landing gear.
605940Okay, let's watch the power when the - landing gear, there, gentlemen.
605956It looks like landing gear deployed from here, FLIGHT.
610028Delete AGS activation and self-test.
610040And a target, right, GUIDANCE?
610046You got the target loaded also, right?
610102How about you guys keeping ahead, here?
610107How about AGS align, FLIGHT?
610112Recommend we don't do that, FLIGHT. All we'd do is just close the DECA POWER breaker.
610116Okay. You don't want to do the test.
610148You ready for DPS pressurization and checkout?
610155We need to configure the DAP.
610157What - what do you need?
610158With what we read on the PAD.
610200Okay, does he - he doesn't do that, here?
610203Wait a minute. Step 2. Okay, yeah. Okay, page 14.
610217How about 3, 4, 5, and 6, there? CONTROL? Although they -
610220We don't need it. That's - part of - that's what we're deleting.
610233Wait. Wait a minute. We need to do step 2, right, GUIDANCE? Oh, okay. TTCA.
610238That's caught later on, FLIGHT. The TTCA to MIN.
610240Well - okay, but do we do it here? If we do it here, let's do it here.
610245You want steps 2 and 3 on page 14.
610247No. Nope. They were discussing the last thing on page 13.
610251TTCA both throttle to MIN.
610255Looks like they've got step 3, too.
610306Affirmative, FLIGHT. He needs to trim the gimbal, not the throttle.
610310To trim the gimbal, in fact if you want to make it simple, just - you can do the DAP set, gimbal/throttle test steps 1, 2, and you've got it.
610321Okay. Do you want to do all of step 1 now, is that what you're saying?
610323That just sets you up for step 2, that's affirm, FLIGHT.
610325Okay. CAPCOM, correction. They want to do all of step 1 and step 2.
610333Is that right, now, CONTROL?
610335GUIDANCE, we're going to do all of step 1 and step 2. Got it?
610343Okay. One other comment, FLIGHT. Down in step 5, he de-arms the DPS, okay?
610349He has to do that particular item.
610351Okay. Well, we're just getting there, we're going through them one at a time, 1 and 2. Okay? Watch him do step 2, there, GUIDANCE. When he gets to it.
610437We can just go to PGNS MODE CONTROL to OFF.
610441Yeah. It'll do the same thing.
610444He's in MIN IMPULSE now, he shouldn't be firing any jets. Except when he hits the ACA.
610450Okay. Why can't he do it in AUTO? Why is this -
610454Okay. If he goes to AUTO, he goes to an ATTITUDE HOLD mode.
610458He'll fire jets to go to the attitude. Hold out the attitude he's in right now. Okay, that's no problem.
610505What do you want us to do, CONTROL? What do you want us to do?
610517We're still hung up on step 1, near as I can tell.
610543Let's go to AUTO per the checklist.
610545Per the checklist, CAPCOM.
610549Okay. You want them to pull his TCA breakers so that he doesn't get any red flags - jets firing, that is?
610555Well, what's the problem with jets firing?
610559I don't see any problem with it. He's in a 5 degree deadband.
610603And the note expects it.
610605And if he gets them it's okay.
610606Yeah. Just do it per the checklist.
610632Go to AUTO and then stop, we'll take a look at it.
610634Go to AUTO and then what?
610635And then stop. That's the question he asked. So he just wants to go to AUTO and then take a look at it.
610641And then he gets the thruster firing, and then what?
610643Okay, you see it - watch it settle down, and then - and then we proceed on to test.
610647Alright. That's what you want to do.
610657Will they stabilize with the docked configuration all right?
610701It should, FLIGHT. We've got the DAP set up for it.
610704Okay. Okay, let's watch it.
610712We've got no firings, FLIGHT.
610737Getting a little thruster activity.
610740Y'all, GUIDANCE, down there, FLIGHT.
610743You getting that GO, yet?
- From MIT on the docked/hybrid burn configuration.
610745Negative. We haven't received it yet, FLIGHT.
610746What's your estimate on it? We need it for the burn.
610749We're getting it right now, FLIGHT.
610752Okay, you watch his loading?
610807Okay, he's loading his gimbal now, let's watch him.
610810Okay, watch the gimbal trim there.
610826Closest approach will be 136.5.
610844He needs to - on step 2, there, when he loads VERB 48 NOUN 46, the DAP load 32021, that was not correct on the DAP. He's got our old DAP mode in right now, he didn't put that in.
610854What do you want us to do?
610855He should go per the checklist, 32021.
610858What - okay, where is that?
610919He can do that after he gets through the test, no problem.
610922Well, okay, but it's there for some reason.
610929FAO, how are we doing on time?
610931FLIGHT, we are sitting alright. The only other thing we've got left is the DPS press. And -
610939And then we go into the 6 minute?
610944Keep - keep track of us, here. Spencer, about -
610946Okay, you ready for the gimbal?
611001Okay, and one other point that's brought out here, we've got a 4-jet ullage loaded in the DAP, and we've got 2 in the PAD.
611011What do you want us to do?
611027Okay, to get - to make it agree with the PAD, the DAP load would be changed to be 31021.
611032Well. Do you want to - why don't we just leave it the way it is?
611036As far as I'm concerned we can leave it the way it is. If that's fine with FDO.
611037RETRO, FDO, you copy that?
611040You copy that? We're going to do a 4-jet. That's what we've got loaded. That alright with you?
611046Go with the way it is, then, FLIGHT.
611047Yeah. CAPCOM, mention that to him so he doesn't think of it later and get confused. We're going with the 4-jet, vice the 2-jet on the PAD.
611055Okay. Are we seeing his gimbal go where it's supposed to?
- In this case, the DPS engine gimbal; the test ensures that it can move about as expected.
611057Yes. It's over against the stop and coming back now.
611203What numbers did we actually read out?
611207We're within about 0.3. We're - plenty close.
611213The what? Wait a minute, didn't you want the engine arm off?
611217Okay. Everything else is okay? Steps 3, 4, 5, and 6?
611222From what I can see, it is.
611226Alright. You're ready for pressurization -
611227You don't have any question about that, then, do you? CONTROL?
611230Alright. Yeah, we're ready.
611235Are we coming up on another OMNI?
611313Okay. Keep your eye on it, okay?
611346Yeah. We delete it all, CAPCOM.
611406Okay, everybody. We are holding at about the 6 minute point in the checklist.
611410Okay, at the bottom of page 15, we've got a new DAP. We've got 31021. You want that in there?
611415That's what put us in a 2-jet boot, FLIGHT. That will put us in 2-jet system boot for the ullage.
611423Yeah. We'll leave it where it is, Jack.
611425We told him 4 jets, that's what he's got.
611428And we - we - has he passed page 15?
611431He's on 16 now, right? Yeah, he's into it. GUIDANCE, FLIGHT -
- I'm waiting for that GO.
611437We watched his P30 here, it looks good.
611439Yeah, I know. But have you got somebody talking to MIT?
611441They're still talking to them, haven't got an estimate yet.
611444Well, we have 15 minutes to the burn.
611448How do I do this burn if I get a NO GO on - DAP control?
611453Okay, standby 1, I'll give you a rundown on that, FLIGHT, put my thoughts together.
611500I'd recommend going ahead and doing this burn if we don't hear from MIT. They feel it'll work, without the run.
611512Everybody feels that it will work.
611516Okay, well what do we do during it if it looks funny, is my question?
611546PGN - okay, you want to do a PGNS AUTO or TTCA?
611550TTCA, CAPCOM. We recommend TTCA to the attitude.
611605INCO, what's our OMNI for this burn attitude?
611611Does he have it on there now?
611615That attitude doesn't look like what I've got on the PAD, here.
611626I'm looking at it. Standby.
611634GUIDANCE, FLIGHT. You copying that?
611637What's on the ball right now?
611640What angles are you looking at, CAPCOM? You looking at the ball angles?
611644I'm looking at all of them. I'm looking at what he's got on the 50 18 on the DSKY, and also what he's got on the FCDUs -
- VERB 50, NOUN 18, the auto-maneuvering command.
611652FLIGHT, the pitch and roll look great. The yaw - the only reason it looks different is just because he's sitting there right now.
611702With the attitude he's at presently. The pitch and yaw - and roll are correct.
611708Yeah. On the DSKY. Is that right?
611713Yeah. The FDAI is different.
611715FLIGHT, we're looking at the FCDUs and they're correct.
611718Mmhmm. How about yaw? That's the one that's out yet? And is he moving in that axis?
611722Yaw doesn't matter, FLIGHT, that's about the thrust vector. That's just where he happens to be.
- One will note, however, that the engine gimbal setting is probably particular to the yaw angle, particularly if they have no TVC.
611727It's not constrained - it's not constrained in yaw.
- for him to maneuver in the attitude we gave him in the -
611731Do you want him to go to a particular yaw?
611737We okay on the OMNI? That we're on?
611745INCO, we okay on this OMNI?
611747Yes. The OMNI they're on will be good.
611749Okay. GUIDANCE and CONTROL, FLIGHT.
611751I still have a question as to what you want me to do if somehow or other something turns up in the guidance during this burn.
611757Okay, I have the recommendation, FLIGHT.
611800Okay, with tur - setting up the burn, we would turn the ENGINE GIMBAL switch to OFF, we'd go to PGNS ATT HOLD, MIN IMPULSE on the - on the -
611811Wait a minute. ENGINE GIMBAL - this - wait a minute. We're in the burn, and this is what you -
611814Oh. This is during the burn you're talking about?
611817That's when this started. What do you want me to do for -
611819Okay. If he's in the burn, they'd go ENGINE GIMBAL off and just use the TTCA to hold attitude. And then as he can, to turn the MODE CONTROL switch to ATT HOLD.
- It's exactly the same recommendation.
611834MODE CONTROL to ATT HOLD.
611848Yeah. ENGINE GIMBAL off, MODE CONTROL to ATT HOLD, and utilize the TTCA.
611854Okay. So you changed the order.
611857Well, this MODE CONTROL to ATT HOLD, he can do that - he should do that as soon as he can, but that - the most important thing is he get attitude control, and he has to do that with the TTCA. So it'll probably be a simultaneous thing.
611908Okay, FLIGHT. Now, you verify his attitude?
611911GUIDANCE? You verify his attitude is okay?
611916He's not at attitude yet, FLIGHT.
611920Roger. He is moving. When he gets there, he'll be in good shape.
611923Is there any way we can check this now, is there a star out of his window or anything?
611927We're running this - right now, we're running to see if there is a star available at the attitude he's maneuvering to.
611933There wasn't at the other atti - previous one that we had.
611937But he's at a different - going to a different yaw, so we're checking it.
612027If we don't get to attitude soon, we're going to be running behind here.
612033Okay. How far away are we?
612035I'm in the same boat as -
612038GUIDANCE, what are the DP - IMU attitudes that are on the DSKY that we're looking for?
612046What attitude will you read on the DSKY when he's in-attitude?
- is yaw. Pitch is 178.1, and roll is 4.47.
612101He's just about there. He's right there now, FLIGHT.
612106We got any physical reference he can use?
612108Okay. Have you seen any star yet?
612117GUIDANCE, you like the attitude?
612120Looks good, FLIGHT. The attitude looks good.
612127Sun is out the forward window. That pretty much obscures a star.
612138Have you got anything on confirming the attitude?
- It's important to remember that the crew still have not been able to perform any kind of alignment on the LM, so they are still counting on the previous platform alignment they transferred over from the CSM, which may have drifted for about a dozen reasons.
612142Negative, FLIGHT. The only star available is star 86, there.
- There is no star 86. He is most likely referring to star 46 - the Sun.
612148FLIGHT, MIT will not have a run on this thing.
612152Okay, now - but it is the judgement that it is okay to use?
612157It's the judgement of the software people it's GO - it's good.
612221Okay. Could we possibly look ahead here and get some of these done so it doesn't get too crowded right by the start of the burn? There's a couple of items that need to be taken care of.
612230Well, we need to get THROTTLE CONTROL to MANUAL; he's in AUTO right now. It's over right - in the 4 minute segment. And we need to get VERB 65 in.
612240Okay, what's the matter with him going through the nominal checklist?
612242He's in attitude, we're at the 6-minute point -
- that's comfortable. I don't want to change anything, Hal.
612315Jack, your opinion: think it would be worth reviewing that if he sees any kind of rates or anything to go ENGINE GIMBAL OFF, MODE CONTROL ATT CONTROL - ATTITUDE HOLD, and TTCA? You think it's worth reviewing with him?
612335I don't think it would hurt it to talk it over with him.
612356For your information, our water rate's dropped down a little in our favor.
612406Yeah, I just mentioned it to him.
- I noticed on page 17, MANUAL THROTTLE -
612442FLIGHT, while he's going through that, you might flag him on page 17 -
- THROTTLE CONTROL AUTO should be THROTTLE CONTROL MANUAL.
612450And you can delete PQGS turned on at the bottom.
612453Okay. CAPCOM, you got that? THROTTLE CONTROL in the middle of that stuff at 4 minutes -
612502How much - how much you want ullage?
612505We can just let it go ahead and start ullage automatically now, FLIGHT.
612507We'll let it go automatically, Jack.
612510He needs to go ahead and hit ENTER on his program and proceed on the P40.
612514Okay. He needs to do an ENTER and proceed on, CAPCOM.
612518Just an ENTER, FLIGHT. Just an ENTER.
612522Oh, he did it, FLIGHT. Standby.
612539And propellant quantity down at the bottom, don't worry about it. It's not on.
612548CAPCOM, would you read them up that takeover?
612552If you have it, there. Here it is if you don't.
612621It's for AUTO THROTTLE, FLIGHT.
612623It's for AUTO THROTTLE. That doesn't say much to me, GUIDANCE, but -
612630We burn MANUAL, you know, GUIDANCE.
612631He's gotta manual-throttle the thing, FLIGHT.
612634He needs to put his throttle to MIN, also, FLIGHT.
612640Yes. He's at 29% now, roughly.
612643Okay. CAPCOM, he needs to put his -
612644Standby, disregard that.
612646I can't tell; he hasn't armed the DPS yet, but he needs to confirm that he does have it at MIN.
612712Won't that - CONTROL, FLIGHT.
612715ATTITUDE HOLD and TTCA, won't that fight itself?
612718Negative. He's in MIN IMPULSE, FLIGHT. He goes ATT HOLD, it turns the jets off.
612730Okay. How are you set up for 2 minutes?
612733What's that Tig counting down to, GUIDANCE, the ullage?
612738Negative, FLIGHT. Engine ignition.
612741Okay. What is - why is our clock counting a different number up there?
612744For the time delay, FLIGHT, from -
612746That's an awful big one.
- you're reading his DSKY.
612751Yeah, he is ahead of us.
612756FLIGHT, RETRO. I've got an ignition time of 1:47. 1:45.
612808Say again? GUIDANCE or RETRO? Is he loaded correctly?
612817Wall clock is wrong, FLIGHT.
612823Okay, how do you like his configuration at 1 +30?
612825CONTROL, everything okay with you?
612828We haven't seen the VERB 65, but that's okay if he doesn't get it.
612833You satisfied with the throttle, or is he not armed yet?
612835He's not armed yet, FLIGHT.
612850All good here at 1 minute.
612913Still on VERB 65, FLIGHT.
612917Do you want to tell them?
612919Yes. Tell him we need ENGINE ARM. He's got it. We're at low throttle point.
612924We need a VERB 65 ENTER.
612926Is that what you're telling me, CONTROL?
612950We have ignition, low throttle point.
612959Rates are holding good, huh?
613026Okay, how about what's left over?
613030Any requirement to trim?
613038Well. Kind of hard to do that.
613106FLIGHT, TELMU. He should - MASTER ARM OFF.
613108And he can go back to MIN IMPULSE when he desires, FLIGHT.
613111Okay. Well now, he's got to go through a number of things, right?
613121Okay, CONTROL. The next question is what control mode, if any, do you want to be in, here? Work with the back room. Do we want to try to set up some kind of PTC in AGS or are we just going to power down, let this thing drift?
613132Okay. Let me pull my thoughts together for a minute, Glynn.
613134Yeah. Okay, but you have somebody work that -
- I want you to watch the configuration, here.
613204You got a minute to talk?
613210How are we doing? Are we getting configured MASTER ARM?
613212No. We've still got the MASTER ARM ON.
613213Yeah, you'd better have them take the MASTER ARM OFF. CONTROL, anything for configuration?
613218The only thing I might recommend, if he wants to - is a VERB 76 but I'm happy with the way it is right now.
613224Okay. We're going to turn the PGNS down here, pronto.
613227Yeah, we've got to get the AGS turned up, though - and I've got the procedure here to give -
613230Well, now, do we? Have to get it turned up?
613236How about just drifting?
613239Well, that's what I'm asking you to check.
613240Yeah, okay. But let's not turn the PGNS off right quick-like. Let me check for you.
613252That's what we're going through right now.
613306If you're going to do something with powering down, you'd better do it quick, because I'm going to have to make you do a handover here, and it's probably going to cost you COMM for at least 5 minutes.
- Between MSFN ground stations, as the Earth rotates.
613314How soon? Are you going to have to hand over?
613317Well, the handover's going to have to go on here in about - 12, 13 minutes.
613321And we want to turn off the receiver - transceiver for 5 minutes up here.
613402Do you have any requirement for the PGNS anymore?
613406I'm not turning it down now. Look - - - go ahead.
613411The current situation is - is that we're checking about the PTC. We had - do we have an AGS procedure for setting up a PTC now? CONTROL? That people think might work?
613425Do we now have a procedure that people think might work in AGS?
613429We don't have a procedure?
613430Not right now. In AGS, for PTC.
613436Well. It all rapidly gets academic, then, huh?
613447Jim's checking to see what he wants to tell us about PTC -
613449We're getting input from SPAN, it looks like no issue here - there's no PTC required.
613453Okay, well, we'll wait and see in a minute. If that's so, there's no need in powering the AGS up.
613502Okay, and if that's the case, then we'll go ahead down. The only reason I'm delaying powering the PGNS down is to be sure we don't need the AGS. It sounds like we don't know how to use it anyway, but I - give them 2 minutes and we ought to know for sure.
613515As I understand it, we're doing another burn at roughly 79 hours?
613518Are we doing another burn at 79 hours?
613520Plan on that. Yes. I don't know whether we are or not -
613522How are we going to get alignment?
613529Can you turn off the thrusters -
613531Affirmative, then he can go MODE CONTROL OFF, whatever he desires.
613536Stand - standby on that, FLIGHT. Standby on that.
613537He asked if he could turn off the thrusters.
613538Standby on that. One moment, FLIGHT.
613544The reason I ask: if we turn everything down now, and then do another burn at 79 hours, how are we going to get our alignment?
613556FAO, when is the shadow of the Moon that we might get a P51 and 2?
613600Okay, FLIGHT. Standby and we'll look at that.
613604TELMU, FLIGHT. How much does it cost me to keep the AGS up, as a coarse reference?
613611How many pounds of water? And how many amps?
613658Some items that we can actually pull right now and save some power that they don't need is the ATCA breaker, and the DECA GIMBAL and the DECA breaker.
613705Now wait a minute. We don't want to be out of attitude control, do we?
613708That won't - I won't put you out of attitude control.
613713Okay. That's right. That's the -
613714If you - if you want to save some power right now. We may have to put them back in later when we go to AGS, but -
613721Okay, which ones were they?
613722The ATCA on CB 16, and the DECA GIMBAL and DECA POWER.
613732Yeah. We can sure turn those off.
613733Roger. I suggest we do that.
613736Let's start with the DECA ones, huh?
613740CAPCOM, while we're going through this subject, two items for power conservation would be the DECA GIMBAL and POWER circuit breakers on panel - 16? 11.
61375011 for the DECA GIMBAL and DECA POWER. ATCA is on panel 16.
613758What control now do I have if I turn off the ATCA (PGNS) circuit breaker?
613802Not ATCA (PGNS). Just ATCA.
613804Oh, okay. The ATCA on panel 16, huh?
613808Okay. There are a couple of power items.
613810While we're figuring out what to do.
613832Y'all, one thing you can do -
613849Okay. We confirm they're open, FLIGHT.
613925Can you give us star - ball angles, I should say, for a COAS star check in the shadow?
613938No. No, in the shadow of the vehicles. Looking away from the Sun.
613953GUIDANCE, can you get one of those in a hurry? That would give us a check on the reference before we do something with it.
614000How about - how about the idea he just gave us about using the Command Module optics in manual? To find stars?
614007Well, we can do that now - what's our objective here, to check the platform again?
614017I mean, we can do a lot of things. I want to know why we want to do something.
614041Okay, look, I'm running out of time.
614043Well, we've got to do a handover here. We don't have any choice. To try to make it as quick as possible, I want to turn down the transceiver for 5 minutes, let us push the IU out of the way, and then bring up the carrier after 5 minutes, when it comes on we'll be able to distinguish the LM. That's the quickest way we know how to try to do it. And we hope it works better than last time.
- This is the base frequency that the transceiver locks onto.
614107Okay. Well you gotta hand over now, do you?
614108We don't have any choice. It's going to be one way or another - it's either going to be the hard way or the easy way. I can't guarantee either way.
614115Okay. I wish I knew what we wanted to do, here, before we lost COMM.
614123I've got a recommendation.
614141EECOM? We gave him a GO on that, didn't we? He probably didn't hear it. Hook up the side hatch urine dump.
614146Has he got - has he got it hooked up now?
614159What do you want him to use?
614201Use the normal procedure. Let - - let me explain that.
614206FLIGHT, INCO. I've got a degree left. That's it.
- Before the current dish hits its tracking limit.
614208CAPCOM, we're going to have a loss of COMM here while we switch stations. Let them know that, will you?
614213FLIGHT, that's not what I want to do. I want him to turn the transceiver OFF for 5 minutes.
614221CAPCOM, have him turn off the S-BAND transmitter/receiver.
614236He has to turn off the S-BAND transmitter for 5 minutes while we do a site handover with this COMM situation.
614259Okay, confirmed burn shows -
614301- - FDO, stand by a minute.
614303Unless you've got a problem.
614350That's good enough. That's real good.
614350You ready for the TRANSMITTER/RECEIVER?
614353You ready for that? They're ready.
614356Go ahead, for 5 minutes.
614407He doesn't have to touch the POWER AMPL. Just the TRANSMITTER/RECEIVER, and he'd better hurry.
614444They want to get some kind of roll attitude going if possible. CONTROL, FLIGHT.
614449Can you figure out if we point the thing north, can you give us a mode in the AGS that we can set up a low roll rate?
614457Yeah, we can come up with one, FLIGHT.
614459Could I have - could I ask for a little quiet in the room, please? It's getting awful noisy in here.
614505We can work on that, but I've got something in my mind here, that I think we ought to do first.
614509And that is to bring the PGNS - bring the AGS up, take the PGNS alignment to it, turn that PGNS off.
614519Okay. As soon as we get the COMM.
614521And I've got the procedure for doing it.
614832When are we going to have the timing that we're in the Moon shadow?
614836I'm trying to find out from FDO now, when he's going back to reference with it, FLIGHT.
614840Okay. Pronto, okay? As soon as you can?
614846Would you like some post-burn data?
614850Okay. Closest approach 136.75.
614854That's based on the confirmed maneuver?
614900We've got a gamut entry interface of -6.53.
614905Okay. I'm - with - that's all coming out nominal, then.
614908Roger. What's even better is that the doppler is within 7 cycles.
- From the ground tracking station.
614914So you think the doppler confirms it.
614916The doppler says that we're - we did the right things, that's affirm.
614955FDO and FAO, when are you going to have the time for me when we're behind the Moon?
- The idea here, first mentioned some minutes ago, is to give the crew some stars to check while the Moon is between them and the Sun, and thus when the glare problems they are having should be minimal. This would also be pretty close to the PC+2 burn at roughly 79 +30 hours, minimizing the length of time the platform must be maintained.
615058Hold on a second now, Jack.
615100- - you're on my loop, Ed.
615116What's the conclusion? We can keep the IMU up?
615127And we've got the water?
615132Well, we may have to turn off some other things.
615152Are you guys coming together with what's being discussed up here for a recommendation - I'm being told that we could conceivably leave the IMU up in the LM - turn the LGC, I guess, OFF right now, leave the IMU up, and power down post-PC+2 DPS burn.
615212Are you involved in all that?
615213Yeah. I have to look at the total load, there, of course. We've been kind of involved with the EPS concern.
615218Bill Peters has been in - Bill, would you, quick, tag in now -
- I'd like, quickly, to know what you want done.
615351TELMU, FLIGHT - gentlemen, it's getting noisy in the room.
615355Let's keep down the conversations.
615412Okay. Go ahead. Calling, FLIGHT.
615414One - CONTROL. One thing to consider, Glynn, is if we do this, we're going to have to have - implement a method of keeping them out of gimbal lock.
615423I guess they're just going to have to watch it.
615424He's got nothing to watch on board. We're powering everything down.
615427No, we're going to leave the IMU up.
615429Okay. Got to leave the inverters up, then.
615431Okay, well that's what I'm waiting for TELMU to tell me.
615434We need a DAP load to conserve RCS.
615438A DAP load to conserve RCS, CONTROL.
615443Okay. He wants it right now?
615503Recommend he goes VERB 76 MIN IMPULSE, and then keep his eye on the middle gimbal angle.
615509Okay. Is that all you've got to tell them for the DAP?
615510Yeah, the DAP load's okay. But he needs to go MIN IMPULSE.
615515VERB 76. And keep an eye on the middle gimbal angle.
615521I guess I kind of need to know, here, as much as you do -
- if we're okay to leave the IMU up and we can swing it. Then I'd just as soon do that.
615531Yeah. I think that's the way it's looking right now.
615533Okay, how long will it take you to conclude that?
615537Just a couple more minutes.
615558Do we have a PAD for 79 hours?
615620Okay, gentlemen. The proposal before the room right now is to turn down the LGC and to pick up all the rest of the smaller power items we can. Leave the IMU up; TELMU's within a few minutes of -
- coming in on that subject.
615633We can - we can do that, FLIGHT, with the IMU up and the AC. It looks like it would probably -
615638The AC. You mean one ball. Okay. Is that what you mean?
615641Yeah. Inverters. Yeah. Looks like also it would probably be cheaper, power-wise, to turn the steerable on, if we could get COMMs attention here - INCO.
615652Turn the steerable up, since we've got the AC anyway, and power down the POWER AMPL.
615659It's cheaper power-wise.
615700INCO, is that okay with you?
615704That gives us kind of - spotty coverage, doesn't it?
615707We're going to have to get into a different attitude.
615709We're going to have to roll.
615711That's right. We're going to have to get out of the attitude we're in.
615714Can you do it on the high-gain, or - you can't switch OMNIs anyway.
615718But we've got a guy awake.
615719He'll have to do it for us.
615720We've got a guy awake anyway.
615726Will we get high-gain coverage, and then we'll drop off, is that what'll happen?
615729Yeah, it'll go at the end of blockage or gimbal limits and he'll have to switch to an OMNI.
615733Recommend something to me, will you? How many amps do we save?
615736FLIGHT, we'd just save about an amp and a half, so it's not a -
615740And it's not a - it's not a coolant item. It's not a water item, is it?
615742Alright, I'm - let's let that go for tonight anyway. Maybe we'll figure something clever out tomorrow night.
615749Okay, TELMU. Have you concluded on this LGC?
615754We're going to leave the IMU up, right?
615755Yeah, but the computer you want to go down? If we want that, let's get on with it.
615801You ready? You and TELMU, are you together there -
615803Yeah, I'm trying to get - get my ducks in a row with him right now, FLIGHT. Standby.
615810You asked a while ago about some stars. I've got some - I picked out some stars to look - if you - I don't know if he wants to do any maneuvering - the maneuver, it's 180 degrees from the Sun. To center the COAS.
615822Okay. Well, standby with it.
615849Did we just tell him to power the computer down?
615850No, we're just advising on what the plan's going to be.
615956TELMU and CONTROL, have you got there yet?
620000You're GO to power the LGC down?
620003What do you want to do? Pull the circuit breakers?
620005Did you give me something on it? I think Bob Carlton did, didn't you, Bob?
620009You said power down or power up?
620017I'm talking - we're going to leave the IMU up, then. Are you ready to proceed and power the computer down?
620022Negative! I do not want to power the computer down.
620025I'm being told that we can leave it up for the sleep period and it will keep their attitude for them, keep them out of gimbal lock.
- Lunney must be near the end of his rope here.
620034Yes. That's what I've been told. The LGC.
620042Okay. So you'd tell them to leave the computer up also, huh?
620045And that's okay on the profile?
620049It's about 22 amps total.
620051And what kind of control mode do you see them being in, here tonight?
620054Okay, just in a 5 degree deadband ATTITUDE HOLD.
620058Wait a minute. We don't want to be in ATTITUDE HOLD. We want to roll - oh, you want to let roll go?
- FLIGHT's thinking about a PTC.
620102You can't let roll go. It's going to be an ATT HOLD.
620107Okay, but - Hal, can we fly ATT HOLD the whole time? We're going to burn something up!
620113I've got the question in, I haven't got an answer on it yet, FLIGHT.
620118The tentative answer I got was we did not require any PTC.
620124Yeah, the only problem, Glynn, if - in the other mode, if we just leave the platform up, we may drift through gimbal lock and that would defeat the purpose of leaving it up.
620132We have a guy sitting there watching it! We're going to keep a guy up!
620137Okay. And we'll have to leave the inverters on also, then.
620141That's - that was what I thought you were talking about!
620143Negative. I was out of step with you, FLIGHT. Sorry.
620145And we'll set up a roll manually, and we'll let them watch it and we'll do the best we can like we did for Apollo 8.
620149Okay. If he does it that way, he'll have to use hard-over command on the ACA to stop any perturbations, then.
620157ATTITUDE DIRECT CONTROL breaker has to be in. Yes, use hard over on the ACA.
620239Glynn, recommend we go ahead and power the LGC down, leaving the inverter on so we can get an attitude reference off the platform, and leaving - let the guy use the ACA to keep us out of gimbal lock.
620252And set up whatever he can in the way of a -
620255It'll be a PTC, it'll be a pilot yaw -
- okay? But he's gotta watch his roll.
620301He's gotta watch the middle gimbal.
620302Roger. The middle gimbal.
620303Yeah. Okay. Now is that the conclusion and is that - presumably good on the power profile and I want to see that profile by the way, TELMU? You copying what we're doing?
620315We're going to put the LGC down and leave an eight-ball up and let them fly it, set up whatever he can with body yaw.
620322Is that - is that the conclusion?
620325And you've got a power profile that says I'm okay to do that?
620328And you're going to show that to me.
620330Now, we're going to proceed then with the LGC power down. What do we do, pull the circuit breaker?
620336Did you hand me that paper? I think we gave it to you, did we Jack?
620340Is that the paper Carlton brought up?
620342That wasn't - that's not what you want, now.
620344No, it isn't. You're right.
620347You're right. What do I want to pull to power down the LGC?
620357Okay, you need PROGRAM 6, and then pull the PNGS LGC/DSKY breaker on panel 11.
620405You mean put it in PROGRAM 6 -
- and pull the LGC/DSKY -
620412And then pull, on CB11, the PNGS: LGC/DSKY breaker.
620417Do you have a procedure written down in the purpose checklist? G&N dictionary, and if we can refer to it, why I think that would be the way to do it.
620429Do you got it there, Spence?
620435Okay, does everybody copy what we're doing? TELMU, FLIGHT.
620440Would you check with SPAN one more time and be sure they're satisfied with what we're doing, we'll do the best we can to set up a body yaw and let the awake guy watch it. Okay? Could you check on them, be sure they understand what we're doing?
620507GUIDANCE and FAO, FLIGHT.
620509Would you let me - give me the ball angles for the pilots to go nose North? CSM nose North?
620516CMS nose North. Will do.
620547You ready for me to give them the LGC powerdown procedure -
620549Let me get a GO here. CONTROL, you ready? TELMU, I mean - you ready? To get - TELMU, FLIGHT.
620559Does SPAN know what you're doing and agree?
620601I can't get in touch with them right now.
620614We're ready to give a try at the POWER AMPL and the LOW BIT RATE and the DOWN VOICE BACKUP if you want to try it.
620619Wait a minute. Let me get my attitude and everything squared away.
620624Having a hard time getting people to agree with the procedure. TELMU, CONTROL, would you get - to see if the people agree with what we're doing?
620633I'm trying to get the SPAN people to agree with the course of action we have here.
620636I can't get a hold of them, FLIGHT.
620637LGC OFF, and try to set up a body yaw, and let a man up to watch it.
620653And GUIDANCE, I'm standing by for some ball angles from you.
554611Roger. Sounds good. And this is the crew of Apollo 13 wishing everybody there a nice evening, and we're just about ready to close out our inspection of Aquarius and get back for a pleasant evening in Odyssey. Good night.
554840Apollo 13, Houston. The next thing we'd like you to do is to -
- we'd like you to roll right to 060 and null your rates for photography of the Comet Bennett. To do that, we would like you to enable quads C and D. For the maneuver, use all your quads. And in precisely 1 minute, we'd like you to terminate the battery charge on battery B. One other request, we'd like to have you verify -
554914One other request, we'd like you to verify your high gain configuration. We'd like to know what track mode, what SERVO, and what BEAM WIDTH.
554925Okay, Jack. During the TV we were AUTO TRACK, NARROW BEAM WIDTH, and the PRIMARY ELECTRONICS. And we had a good lockup. Just after we started the maneuver, I was able to lock you up and get real good signal strength, and it just seemed that right there at about 239° in yaw, that the signal strength would just drop off and yaw would go to 0 and pitch would go to 90.
555005Roger. We copy, and the TV show was great.
555012Okay, real fine. Okay, I'm going to maneuver to 060, 090, and 0.
555031And 13, we'd like you to check C-4 thruster.
555134Okay, Jack. The battery charge has been terminated on battery B.
555138Roger. We see it, Jack. And we've got a reading of -2° on the docking index. We'd like to know if that's 2.0 precise or if it's 2.1 or 1.9.
555154No. It's -2.0 precisely.
55525913, we've got one more item for you, when you get a chance. We'd like you to stir up your cryo tanks. In addition, I have shaft and trunnion -
- for looking at the Comet Bennett, if you need it.
555520I believe we've had a problem here.
555529This is Houston. Say again, please.
555535Houston, we've had a problem. We've had a MAIN B BUS UNDERVOLT.
- Not "we have a problem," as in the film. The scriptwriters felt the present tense was more appropriate.
- The first reading that the MAIN B electrical bus was dead. It would never recover.
555543Roger. MAIN B UNDERVOLT.
555559Okay, standby, 13. We're looking at it.
555610Okay. Right now, Houston the voltage is looking good. And we had a pretty large bang associated with the CAUTION AND WARNING there. And as I recall, MAIN B was the one that had an amp spike on it once before.
555654In the interim here, we're starting to go ahead and button up the tunnel again.
555704Yes. That jolt must have rocked the sensor on - I see now - Oâ‚‚ QUANTITY 2; it was oscillating down around 20 to 60 percent. Now it's full-scale high again.
555730And Houston, we had a RESTART on our computer. We have PGNCS light and RESTART RESET.
555738Roger. RESTART and a PGNCS light. RESTART and a PNGCS RESET -
555742Okay. And we're looking at our SERVICE MODULE RCS HELIUM 1, we have B is barber poled and D is barber poled. HELIUM 2, D is barber pole. And SECONDARY PROPELLANTS I have A and C barber pole. BMAG temperatures -
555807Okay, AC 2 is showing zip. I'm going to try to reconfigure on that, Jack.
555825We got a MAIN BUS A UNDERVOLT now too, showing.
555833It's reading about 25.5. MAIN B is reading zip right now.
- volts. 29 volts was nominal.
56003413, Houston. We'd like you to attempt to reconnect fuel cell 1 to MAIN A and fuel cell 3 to MAIN B. Verify that quad Delta is open.
560054Okay, Houston. I'm showing - I tried to reset and fuel cell 1 and 3 are both showing grey flags, but they're both showing zip on the flows.
560317Okay, Houston. Are you still reading - 13?
560321That's affirmative, we're reading you. We're trying to come up with some good ideas here for you.
560329Okay. Let me give you some readings - in the interim to help MAIN A voltage, Jack. I've got BUS TIE AC on.
560342In the interim, to help out MAIN A voltage, I've got MAIN BUS TIE BAT A/C on. Or would you rather accept the 25 volts we are seeing on MAIN A?
- These letters are designations, not "alternating current."
- 29 volts was the target operating voltage of the bus. Adding more power sources in series ups the voltage.
56041013, Houston. We need OMNI Charlie, please.
56053213, Houston. We'd like you to verify couple of readings for us. We would like the nitrogen pressure on fuel cell 1. We need the oxygen pressure on fuel cell 2.
560546Okay. Nitrogen on 1 and oxygen on 2. Is that correct?
560623Okay. The systems test 1-A says zip.
560644And 2 Baker, which is 3 oxygen, says 0.6.
5606502 Baker says 0.6, and say again the other one.
560657Fuel cell 1 nitrogen reads 0.
56084613, Houston. We'd like you to open-circuit FUEL CELL 1. Leave 2 and 3 as-is.
560855Okay. I'll get to work on that.
560857And Jack, our Oâ‚‚ QUANTITY number 2 tank is reading 0. Did you get that?
560904Oâ‚‚ QUANTITY number 2 is 0.
560907That's AC, okay. Yeah, that's because of AC and it looks to me, looking out the hatch, that we are venting something. We are venting something out into the - into space.
- In the film, the whole timeline is compressed - including this call nearly 14 minutes following the incident.
560922Roger. We copy your venting.
560928It's a gas of some sort.
560948Okay, FUEL CELL 1 you just wanted it off the line now, Jack, is that right?
560952We just wanted you to open the circuit on fuel cell 1.
560958Okay, she's off the line.
56124813, Houston. We see you getting close to gimbal lock there. We'd like you to bring up all quad Cs on MAIN A, quad C-l, C-2, C-3, C-4 on MAIN A, and also bring B-3 and B-4 up on MAIN A.
56131513, Houston. Do you read?
561322Okay. Can you tell us anything about the venting: where it's coming from, what window you see it at?
561330It's coming out of window 1 right now, Jack, and could you give me the thrusters again?
We'd like - on MAIN A, we'd like Charlie 1, 2, 3, and 4. Also Bravo 3 and 4 on MAIN A.
561608Okay, 13, this is Houston. We'd like you to go to your GNC checklist, the pink pages, 1-5. Do a powerdown until we get a delta of 10 amps. Over.
561703Okay, Jack. Say again that - - for the power down - on the pink pages, the 1-5.
561711Okay. We'd like you to go down that power down procedure until you get a delta of 10 amps. Over.
56175013, Houston. Did you copy our power down request?
561757Roger, Jack. We're - we're doing it right now.
561758Yeah where - where did you say that was located, Jack?
561803That's in your systems checklist, page 1-5.
561827And 13, you might also check for those pages in your launch checklist. They're emergency pages - pink pages, 1-5. And we'd like you to power down until you get -
561837Okay. That was in the launch checklist, Jack.
561842Roger. Power down until you get an amperage of 10 amps less than what you got now. Over.
562206Okay Jack. Are you happy with the amps we have now?
562215Okay Jack, and on this page 1-5, we proceeded right down the list, all the way down. We're right now at BMAG number 2 is in WARM UP.
562226Roger. We copy BMAG 2 in WARM UP. We'll follow you through.
562232Okay, and something is giving us some rates, Jack, both in pitch and roll, so I'm suspecting that maybe it's whatever it is that's venting back there. I've had to use DIRECT in order to stabilize this, and as soon as I do, we're starting to pick up rates again. Can you pick up any jets firing?
562259What direction are your rates in, Jack?
562306It's negative pitch and negative roll.
56244113, Houston. We need to get some more instrumentation up. We'd like you to put INVERTER 1 on both AC BUSES. Over.
562504Okay, you got INVERTER 1 on both AC BUSES now.
562520And Jack, one of the items that we turned off was the - all the fuel cell pumps. Okay, and you might let us know when fuel cell 2 needs its pump back. We ought to take care of that guy.
562547Okay, Fred. We want FUEL CELL 2 PUMPS to AC 1, please.
562555FUEL CELL 2 to AC 1. Roger.
562747OMNI Charlie please, 13.
562806Okay, 13. We've got lots and lots of people working on this. We'll give you some dope as soon as we have it, and you'll be the first one to know.
562829Okay, Jack, and the weird configuration we're sitting in now is we have the hatch installed, we still have the probe and drogue inside the command module, and we're going to stay in this situation until you kind of give us an okay to reinstall the probe and drogue.
562847Roger. We'll give you an answer.
562847Or if necessary, to use the LM consumables.
56321213, we'd like to have you put thruster Alpha 3 on MAIN A, please.
563224Okay, Jack. Are you monitoring the quad temps in quad A - package temps?
56333813, this is Houston. We'd like to power down just a little bit more, so let's get BMAG 2 OFF, and make sure your lights are down. Over.
563350Okay. The lights are down, and BMAG 2's going from STANDBY to OFF.
563428Okay Jack, now I've got a rate -
- we'd like you to open circuit FUEL CELL 3.
563435Open circuit FUEL CELL 3.
563446Okay, FUEL CELL 3 is off the line now.
563516And 13, Houston. We'd like you to turn all your Bravo thrusters OFF, and put all your Delta thrusters on MAIN A, please.
563527All Delta thrusters on MAIN A and all Bravo thrusters OFF. Roger.
56355513, Houston. Turn BATTERY A OFF -
563556Okay, Jack, (unintelligible)
56370713, Houston. We'd like you to isolate your Oâ‚‚ surge tank. Over.
563719Surge tank off now, Jack.
563722Okay Jack, are you copying Oâ‚‚ TANK 1 cryo pressure?
563730That's affirmative, and we're trying to get power to that tank. Standby, we're working on it.
563905Okay, we had a SERVICE MODULE RCS B light, Jack, due to package temperature.
563922Let's read you the lights we got on now: CRYO PRESS, FUEL CELL 1, FUEL CELL 3, MAIN BUS B UNDERVOLT, SUIT COMPRESSOR.
563933Roger, we copy them. And we'd like to build up the pressure in Oâ‚‚ TANK 1, so turn the heaters on manually. We'll watch the pressure for you.
- Overriding the automated circuit meant the heater wouldn't disengage automatically, which could lead to overheating and damage.
563944Okay, do you want to see - we're going to get a MAIN BUS A UNDERVOLT, probably.
563950Roger, we realize that. We feel we can stand 5 more amps on it.
564000Okay, heater on TANK 1's ON.
56415213, Houston. We'd like you to additionally bring on the fans in Oâ‚‚ TANK 1, and we can stand the additional amperage on that.
564203Okay. Bring up the fans on Oâ‚‚ TANK 1.
56443313, Houston. We'd like you to check some circuit breakers on panel 226. CRYO Oâ‚‚ HEATER number 1, MAIN A. And check the three CRYO FAN MOTORS, TANK 1, three phases.
564455Okay, Jack. 226 is configured just like it should be. I got three REAC breakers and three RAD breakers open. All the rest are closed.
- The valves that closed the fuel cell reactant valves were electrically actuated. To prevent accidental closing, the circuit breakers to those valves were normally pulled.
- Fuel cell radiator
564556Jack, looking outside, the number of particles has diminished greatly, almost ceased now, which indicates maybe what was venting has almost stopped.
564609Roger, Jack, thank you. We copy.
564614I'm still getting some rates in negative pitch, though.
564628And 13, we'd like to verify that both BMAGs are OFF, please.
564635Negative. We just have one BMAG. BMAG number 1 is still ON.
564643Okay, Jack. Let's take BMAG 1 OFF.
564650Okay. BMAG number 1 OFF now.
56480713, this is Houston. We'd like you to give us a survey of your displays on MDCs 1 and 2. Give us gauge readings and talkbacks. Over.
564823Okay. We'll start with display number 1.
564830Okay, Jack. On MDC 1, there's nothing abnormal. All the rate indicators are zero. Ball number 2 is frozen, of course: we lost MAIN B.
- You can follow along these readouts on the MDC diagram located here.
564843I've got - ball number 1 appears to be working normally. Right now I'm sitting at roll 0, pitch 180, and yaw about 13°.
564858I'm going to try and hold 0, 180, and 0.
564908Okay, Houston. The center panel - I'm looking at the RCS indicator A. We have a package temperature of 180. Our helium pressure is 3900. I'm looking at fuel pressure of about 180 and percentage of about, I'd say 85%.
564932B is about the same, except that that package pressure is 190. On Quad C, we're looking about the same, except that the package temperature is 100. On Quad D, we're looking at package temperature of 160. All other indications are about the same.
564954CM pressure - RCS pressure is looking nominal. Helium pressure's up around 4000. And package temperature is about - a little less than 80 on ring 1 and about the same on ring 2.
565013And the - talkbacks on the SM RCS, I've got HELIUM 1 now are all grey. HELIUM 2 are all grey. PRIMARY PROPELLANT all grey. SECONDARY PROPELLANT, I've got two barber poles - A is barber pole, B grey, C barber pole, and D grey.
565039Okay. On the ECS RADIATORS, ?? is grey. On the - on the ECS, PRIMARY INDICATOR.
565057Okay, Jack. Starting at the top. Okay. The CRYO TANKS: Hâ‚‚ 1 is reading 230 and the same for 2. Our Oâ‚‚ CRYO TANK 1 is - looks like it's barely holding its own at 300. And, CRYO TANK 2 is reading zip. Our quantities: Hâ‚‚ 1 is reading 73, 2, 74.
565134On the O₂ side, we're reading O₂ 1 at quantity 76. O₂ 2 pegged to full scale high. RAD TEMPs PRIMARY INLET we're reading about 55; RAD OUT is reading about 30, and the SECONDARY OUTLET is reading - reading 52°.
565211And the EVAP OUT TEMP is 45, STEAM PRESSURE 0.17, and GLYCOL DISCHARGE 48. SUIT COMPRESSOR is reading zip. The ACCUM is reading 30; Hâ‚‚O WASTE is reading about 34; POTABLE's reading about 98; SECONDARY RAD INLET is reading about 71; and the RAD OUT is about 30; GLYCOL EVAP TEMP is reading 65, STEAM PRESSURE pegged full scale high; DISCHARGE PRESSURE 9 psi.
565306Excuse me, Fred. I'd like to butt in here a minute. We'd like to have THRUSTER C-1 OFF.
- my last copy is SECONDARY RAD IN.
565327Okay. Your SECONDARY RAD IN, I gave to you 70 - about 72°; the RAD OUT is about 30; the GLYCOL EVAP TEMP is reading about 65; STEAM PRESSURE full scale high, GLYCOL DISCHARGE PRESSURE about 9 psi. The ACCUM - SECONDARY ACCUMULATOR is about 30 - 34%.
565400Our temperatures: SUITS showing about 52°; CABIN about 58°; pressures, SUIT reading 4.1, CABIN at 5. PARTIAL PRESSURE CO₂ is up to a little over 1, about 1.1.
565420On the SPS side of the house, the temperature is 72°, helium's reading 3500; N₂ A is reading 2300; N₂ B about 2450. And our ullage pressures: FUEL is reading about 165; OXIDIZER 170.
565451Fuel cells: FUEL CELL 1, both CLOSED, they're zip; SKIN TEMP 405°; CONDENSER EXHAUST is lower scale. FUEL CELL 2 - right now we've got an O₂ - an H₂ FLOW reading of 0.13 to 0.14, and the O₂ FLOW is right now pegged full scale high although it has been varying depending on thruster activity which has also given us MAIN BUS A undervolts from a steady reading of about 1.1 up to full scale high.
- As thrusters used power when they fired and each load drops the voltage, the thrusters could trigger undervolt warnings when they engaged.
565533The T-SKIN is about 445 and the CONDENSOR EXHAUST 17, correction, 180. Let's see if you want it on the DC indicator: FUEL CELL 1 is 0 amps; 2 is reading somewhere between 44 and about - oscillating 44 to 48, again depending on thruster activity.
565603- is 0 amps. Say again, Jack?
565655Hello, Houston; Apollo 13. How do you read?
565707Okay, 13. This is Houston. It appears to us that we're losing Oâ‚‚ flow through FUEL CELL 3. So, we want you to close the REAC valve on FUEL CELL 3. It looks like FUEL CELL 1 and 2 are trying to hold up okay. You copy?
565726Are you saying FUEL CELL 1 and 2 - 1 and 2 are trying to hold up but we're leaking Oâ‚‚ out of FUEL CELL 3? And you want me to shut the REAC valve on FUEL CELL 3? Did I hear you right?
565740That's affirmative. Close the REAC valve on FUEL CELL 3.
565747Okay. I'll go to the SSR page. Do you want me to go through that whole smash for fuel cell shutdown? Is that correct?
565824Okay, 13. We want you to turn the inline heaters OFF on FUEL CELL 1. Then we want you to go through the fuel cell shutdown procedure on FUEL CELL 3. Read back.
565840Okay. Shut down the inline heater on FUEL CELL 1. We're proceeding with the shutdown, special subroutine, for FUEL CELL 3.
570000Okay. You got OMNI Bravo and we'd like to have you verify that the tape recorder is OFF please.
570010Okay, Jack. I'm sitting here with an 06 18 showing and I can't get rid of it. Oh, standby just a -
570048Okay. FUEL CELL 3 REACs are OFF, Houston.
570154Okay, Jack. Step 2, special subroutine 1 for the fuel cell procedure has been completed.
570430Okay, Jack. I'd like to bring on jet A-4. I've got null on negative pitch control, and - negative pitch control, and right now neither DIRECT or AUTO coils.
570447Okay. You say no pitch in either DIRECT or AUTO? You want to bring on A-4?
570453Yeah, I've got a positive pitch rate and I can't stop it.
570508Okay, Jack. Bring A-4 on. Stop the pitch rate.
570536And 13, we need OMNI Charlie, please.
570546And Freddo, we would like to have you verify fuel cell reactants talkback is barber pole.
570554That's affirm. I watched it and it went barber pole as I threw the switch.
570801Okay. Jack. Let me give you a thruster configuration right now. Able 1, Charlie 1, Able 2 are OFF. Charlie 2, MAIN A, all the thrusters that I call that are ON are on MAIN A. Baker 1 OFF. Dog 1 ON, Baker 2 OFF, Dog 2 ON. Able 3, Charlie 3, Able 4, Charlie 4 on. Baker 3 OFF, Dog 3 ON, Baker 4 OFF, Dog 4 ON.
- The seemingly disjointed order of callouts here is actually the order the switches appeared on panel 8.
570928Okay, Jack. That thruster configuration looks okay.
570935Alright. Okay. Do you want some readings from the systems test meter regarding fuel cells?
570945Standby 1 on that, Jack. Let me ask the EECOM.
570947We've got some incompatibilities here.
571003Okay, 13. We'd like to have you give us those systems test readings on FUEL CELL 1 and 3, please.
571011Okay. 1 and 3 coming up.
571014Okay Jack, 1-A is reading - lower scale. 0. 1-B is reading 3.45. Okay. You only want FUEL CELLs 1 and 3, okay - ignore that 1-B reading. 1-C is reading 3.4. Now, 1-D is reading 2.4. 2-B is reading 0.25.
571110Roger, is that 2 Bravo, Fred?
571115That's 2 Bravo is reading - oh, about 0.25 to 0.3.
571139Okay. 2-C is reading 4.1.
571215Roger, 4.0. Say again what it is, please.
571258And 3-D is reading 1.95.
571408And Houston, 13. Oâ‚‚ tank pressure number 1 is less than 300 now.
571414Roger. We're seeing that. We confirm it.
57150513, Houston. We're going to have to have you go through the shutdown procedure on fuel cell 1. Our Oâ‚‚ pressure is going down as you note and the temperature confirms it. Did you copy?
571524Okay. Well, what bus configuration - what MAIN BUS do you want powered?
571537Okay, Jack. We want you to leave the bus configuration as it is. FUEL CELL 2 on MAIN A.
571552Okay, Jack. We're proceeding with the shutdown procedure for FUEL CELL 1.
571635And 13, Houston. We'd like you to isolate the REPRESS package, please.
571642Isolate the REPRESS package. Roger.
571645I can confirm REPRESS package is OFF.
571648Roger. So now you've got the REPRESS package and the surge tank isolated. Is that affirm?
571658Okay. Now, this is - we're ready to close the REACs on FUEL CELL 1. Is that right?
- one last - confirmation. Okay.
571741Roger. We're - we're giving you one last -
571742We want to just get one last confirmation.
571745Okay, Jack. We're getting that last confirmation. Standby, please.
571801Okay, 13. We verify that we want you to close down - shut down FUEL CELL 1, close REACs valve.
- FUEL CELL 1; close the REACs valve.
571820REACs valve on FUEL CELL 1 is closed.
571845Okay, Jack. I can confirm step 2. The FUEL CELL shutdown procedure is complete for FUEL CELL 1.
57195813, we recommend that you enable B/D ROLL in the DAP. Over.
57202413, Houston. We're working on the big dish now, so turn the HIGH GAIN POWER switch off, please.
572055Okay, Jack. When we got the loud bang, we got also a restart. Did you copy that? Is - does GUIDO want anything, a VERB 74 or anything done with the CMC?
57215513, Houston. We're ready with a VERB 74 now, please.
572355Okay, Jack. It looks like Oâ‚‚ tank 1 pressure is just a hair over 200.
572402We confirm that here and the temperature also confirms it.
572409Okay. Does it look like it's still going down?
572413It's slowly going to zero, and we're starting to think about the LM lifeboat.
572421Yeah, that's what we're thinking about too. You want me to do a quick P52? It kind of looks like - we've been talking it over, and it kind of looks like we'd probably align our plats - LM platform with our platform and then power down the CM, and keep the LM powered up doing a DPS - whatever DPS burns you give us?
57245413, we're not going to concern ourselves at the moment with a DPS burn; it's going to be some time before we'd get to that. But we're working on other procedures to give you, which will allow us to use the LM systems. Over.
572641Apollo 13, Houston. We'd like to charge BATTERY A now.
572647Charge BATTERY A. Roger.
572713And Jack, in regard to your question about the P52 and LM platform, it's - there's no need to worry about that now. We wouldn't be using the LM platform for - until about 79 hours, so let's go as-is on the platform for now. Over.
573014And Jack, we've turned off the waste dump heater. If you're going to consider dumping any more waste water, we probably ought to do it while the duct is warm there.
573039Okay Jack, let's keep the water; no need for a dump right now.
57321613, Houston. We see the PROP ISOL valve on RCS Quad Charlie closed, so we'd like to also disable AUTO RCS feature in Quad Charlie.
573230You want us to isolate the AUTO RCS features in Quad Charlie?
573244Okay Jack, I didn't plan to reset that Quad Charlie PROP ISOL valve. Do you want me to do that?
573254Okay, we just tried it and Quad Alpha and Charlie barber poles are showing.
573303Okay, Jack. That's the secondary propellant are barber poles on Alpha and Charlie.
57344713, Houston. It won't do any good to try to power the propellant valves on A and C, so we want you to disable the AUTO on RCS Charlie. And we have a procedure for getting power from the LM we'd like you to copy down.
573511That sounds like good news.
573606Okay, Jack, about how long is it?
573613It's not a very long procedure, Fred. We figure we've got about 15 minutes' worth of power left in the Command Module, so we want you to start getting over in the LM and getting some power on that. And you ready to copy your procedure?
573642Okay. In the CSM on panel 5, circuit breakers LM POWER 1 and 2, OPEN. Then LM POWER switch, reset and release. In the LM, on panel 11 and panel 16, XLUNAR BUS TIE, both circuit breakers CLOSE. On panel 16, circuit breaker ASCENT ECA CONTROL, CLOSE. On 16, DESCENT ECA CONTROL, CLOSE. On panel 14, put your BAT 5 NORMAL feed ON. BATs 1, 2, 3, and 4 LOW VOLTAGE taps, ON. BAT 5 NORMAL feed, OFF. ASCENT ECA CONTROL, OPEN. You copy?
573825Okay. In the CSM, on panel 5, we want CB LM POWER 1 and 2, OPEN. Then the LM POWER switch to reset, release. In the LM, panels 11 and 16, XLUNAR BUS TIE breakers closed. The DECSENT ECA CONTROL closed. On panel 14, BAT 5 NORMAL feed ON, followed by BATS 1, 2, 3, and 4 LOW VOLTAGE taps ON. Then BAT 5 NORMAL feed OFF. Then ASCENT ECA CONTROL breaker OPEN.
573859That's a good readback, Fred.
573915And 13, Houston. As a final effort here, we'd like you to turn on the fans in tank 2. Over.
573923Roger, understand. Turn on the fans in tank 2.
573935You want the Oâ‚‚ fans in tank 2, Jack?
573938That's affirmative, Jim.
573945Oâ‚‚ tanks - fans in tank 2 are on.
57413213, Houston. We'd like you to start making your way over to the LM now.
574138Fred and Jim are in the LM.
574250Okay, you still with us, Houston?
574303Okay, Houston. You read, 13?
574306Reading you loud and clear, Jack. I've got a procedure for -
574315You've got another one? Go ahead.
574318I have an activation procedure. I'd like you to copy it down.
574327It's just four lines. Go to Activation 1, do step 3. Go to Activation 11, omit step 1. Do Activation 12, and then go to Activation 13 and do step 1. Do you copy?
574354Okay. Is that Activation 1? Do step 3. Is that correct?
574403Activation 11, omit step 1, do the rest. Is that correct?
574410Do Activation 12 and Activation 13, step 1.
574425Okay, Jack, pressure in tank 1 is approaching 100psi. What's going to be the symptoms of this fuel cell starting to drop off?
574452Standby, Jack, we'll get the word on that.
574506And Jim, when you get to the end of that procedure, we'd also like to have you put the DEMAND REGs to CABIN.
574515DEMAND REGs to CABIN. Roger.
574531Jack, was that Activation 1 step 3 only, or all of Activation 1?
574539That's - go all the way down to step 3, Jim.
574544Activation 1 to step 3. Roger.
574648Houston, Apollo 13. Never mind.
574659Oh, we were curious about Activation 11 on the VHF.
574817Jack, this is Houston. We want you to keep the IMU up and keep the lights on so you can see in there, and leave battery off - BATTERY A off. And at the appropriate time, we'll put it on MAIN A. And we're going to keep the IMU up so as we can get a coarse align in the LM.
574838Alright. Real good. Right now, we're charging BATTERY A. Do you want to discontinue that?
574846Discontinue the charge on BATTERY A, Jack.
574922Okay, Jack. I discontinued charge on BATTERY A. You give me the call and I'll turn BUS TIE AC on.
574932Roger. And we want you to keep the lights up and the IMU on.
574948And Jack, we'd like you to leave the COMM configuration as-is until we get COMM with the LM.
575108And 13, this is Houston. I've got another procedure for the LM. A short one.
575115Okay, ready to copy, Jack.
575117Okay, on panel 11 we'd like you to close the LGC/DSKY circuit breaker. Then we want you to go to Activation 25, do steps 1, 2, and 3. Then go to Activation 30, and that will give us a docked IMU coarse align. Over.
575141Roger. Panel 11, close LGC circuit breaker. Activation 25, do steps 1, 2, 3, and then do complete Activation 30. Is that correct?
575150That's affirmative. On panel 11, LGC/DSKY circuit breaker closed.
- A somewhat unnecessary clarification, as the only thing labeled "LGC" on panel 11 is the LGC/DSKY breaker.
575316And in the LM, let's go to panel 11 and close the SUIT FAN circuit breaker and get SUIT FAN 1 cranked up.
575326Okay. Panel 11, close SUIT FAN circuit breaker, and we'll get the suit fan cranked up.
575348And Jack, in the CSM, go to BYPASS on the radiators and turn your GLYCOL PUMP off.
575401Pull the BYPASS; GLYCOL PUMP going off.
575543And 13, in the CSM we want to verify that all the FUEL CELL PUMPs are off, and we want to have you turn off the Oâ‚‚ FANs in TANK 2.
575556Okay. Tank 2 fans going off.
575600Okay, that leaves me with TANK 1 FANs on, and TANK 1 HEATERs on.
575610FUEL CELL 2 PUMP going off now.
575620And Jack, leave them both on in TANK 1.
57575613, Houston. We've got AOS on the LM here.
575923And 13, this is Houston. In the LM we'd like to have you go to Activation 12 step 3, which is get the batteries on high taps. Over.
575941How you going there? Activation 12, step 3.
- For a while here, Aquarius has their audio mode set to VOX, so you'll hear a lot of their chatter back and forth that they don't realize is being transmitted.
580018Okay. And Jack, how do you read from Aquarius?
580023Aquarius, Houston. Say again, please.
580028Okay, I was just making a COMM check here. I'm on high voltage taps.
580032Roger. We see them, Fred, and I'm reading you loud and clear.
580038Okay. Didn't think I'd be back this soon.
580057Do it right. Take your time.
580132And Aquarius, Houston. We'd like you to - on your alignment, can you continue right on through the fine align Activation 31? Go right on through step 7. Over.
580145Okay, you want to go on 31 through step number 7, Jack.
580150That's affirmative. And Odyssey, we've got another configuration for you. All 16 RCS AUTO SELECT OFF. All RCS heaters off. Over.
- This is likely a continuation of the EECOM power-down list handed earlier to CAPCOM.
580206Okay. I can verify all heaters off. Jack, I've got to keep a fairly minimum deadband until I get through this coarse align.
580227Okay, VERB 41, NOUN 20. Okay.
580242You want plus? Plus or minus? +302.43? Is that right?
580312Okay, let me enter it. Okay, what's the next one? +347.78. 347.78. Okay. 081.3. Is that right? ENTER. Okay.
580354Odyssey, Houston, BATTERY A on.
580403Houston - okay, I want you to double check my arithmetic to make sure we got a good coarse align. The roll CAL angle was -2°. The Command Module angles were 355.57, 167.78, 351.87.
- This the docking angle index from the very beginning of this audio.
580436Okay, Jim. We copy the roll CAL at -2.0. Command Module is 355.57, 167.78, 351.87.
580523VERB 41, we've done that. Okay.
580528Aquarius, Houston. Request HIGH BIT RATE, please.
580538That's affirmative, Fred. Won't cost us anything.
580622Odyssey, Houston. We'd like you to, on your COMM configuration, go to PRIMARY POWER AMPL OFF, LOW BIT RATE, and DOWN VOICE BACKUP. Over.
580642And Aquarius, we need your SUIT GAS DIVERTER to CABIN.
580702Houston, I've gone to PRIMARY POWER AMPLIFIER OFF, LOW BIT RATE, DOWN VOICE BACKUP.
580711Okay, Jack, thank you. And Aquarius, your arithmetic looks good on the coarse align there.
580720Okay. Okay, standby for an ENTER.
580740Get the GET; we need the GET. What is it? What's that? 58? 58:07?
580923Here are the gimbal angles. Command Module, 356.69, 163.42, 346.67. Aquarius is 302.26, 345.92, 011.79. Over.
580947Okay, Jim. I got Command Module 356.65, 163.42, 346.67. Aquarius, 302.26, 345.92, 011.78.
581018The LM middle gimbal is 011.79.
581219Odyssey, Houston. We need a COMMAND RESET on your - on your COMM, and then we'd like you to power down the CMC, power down the IMU, heaters off on the IMU, but leave your BATTERY A on.
581313Houston, this is Odyssey. Go ahead.
581320Okay, Jim. I think I'm reading Jack, now. But what we want him to do is give us a COMMAND RESET. And then power down the CMC, power down the IMU, turn the IMU heater off, leave BATTERY A on. Over.
581419That's just about 80 - in fact, 82 hours out of the two primary cartridges. That's two guys. 44 is what LC8 got. That would be 88 hours. We got a secondary, you're right. We're listening.
581447Yeah, Jack, did you copy down about the CMC and IMU?
581452Yeah, Jack; I read it back twice to you. COMMAND RESET, which I've done. I'm about to power down the IMU, power down the CMC, turn the IMU heaters off, leave BAT A on.
581507That's affirm. Thank you.
581511Okay, I just got a MASTER ALARM and MAIN BUS A UNDERVOLT. And I'm starting to power down, now. We've lost the -
581521The only advantage to doing it early - if we can power back - the LM back down. The only advantage to doing it early is you can do a big burn now and a midcourse and then power the LM down. Otherwise, we've got to keep the LM powered up clear until we get around the Moon.
581545Plus, it would be inside on the burn.
581557I just hope the G&N hangs up on - hangs in on this one - I'd sure hate to do that one manual.
581606Odyssey, Houston. Couple circuit breakers for you. On panel 276, on your INSTRUMENTATION POWER CONTROL, open CB number 3 and number 4.
581633Okay, Houston. Panel 276, INSTRUMENTATION POWER CONTROL circuit breakers -
581637- you got a lot of light -
581647That's affirmative, Odyssey. And also get your SCS electronics package and power off, and your FDAI POWER/GPI off, and your AUTO jet SELECT, all 16 off.
581707Okay, well wait a second. Let me - let me get the CMC powered down.
581723Jack, while he's doing that, copy down what you just said again. I want to write it down.
581736Aquarius, we need to get your sublimator powered up. Activation page 20 and Activation page 21 step 3. Over.
581753Roger. Activation 20 and Activation page 21, step 3, sublimator.
581800That's Activation, page 20?
581809Okay, Jack. Now I have powered down my IMU. I have no control at all. I'm going to turn my 16 jets off. Say again the other things you wanted?
581828Okay, Jack. We'd like you to turn off your Oâ‚‚ TANK 2 heaters and fans. Correction - TANK 1. Turn the fans and heaters off.
581840Okay. And Jack, can we turn on the FDAI circuit breakers so we could have a ball to see if we go to gimbal lock or not?
- Another oversight in the rushed procedure - they are flying blind.
581853Houston, he's going to give a 16 NOUN 20, Jack. And okay, I've got Oâ‚‚ heaters and fans off in TANK 1.
581915And Jack, let me know if we get close to gimbal lock, would you?
581925Jim, we didn't want you to power down the ball in the LM. We wanted you to power down the ball in the CSM.
581940Jack, they haven't powered down -
581942Jack, we don't have the balls powered up in the LM.
581945I have the CMC and IMU in the command module powered down. The heaters are out.
581956And the EVAP flow valve, that's open now. And I've undone my suit hoses here and opened up the suit flow valves. So we've got air flowing in the LM now.
582011Okay, Jack. Will you say again the SCS items you wanted me to power down?
582045Okay, Houston. Do you read Odyssey?
582055Hello, Houston. How do you read?
582102His gimbal lock and ours are different, Jim.
582109Apollo 13, Houston. Say again, please. You were cut out.
582115Okay, Jack. Do you want me to proceed by the SCS powerdown checklist? I did not copy the SCS items you wanted me to power down.
582132Okay, Odyssey. We want you to go SCS ELECTRONICS POWER OFF.
582140FDAI POWER/GPI OFF. AUTO jet SELECT, 16 -
OFF. And all your ROTATIONAL CONTROL POWER, OFF.
582151It's done. ROTATION CONTROL POWER, DIRECT, and AUTO closed OFF.
582159Okay, Jack. Tell me there - we need to know when we're getting close to gimbal lock in the LM. We have no balls right now.
582206Okay. We want you to power up your eight-ball. We want you to get your RCS heaters on. Pressurize the RCS and open up the MAIN SOVs. Over.
582223Okay Jack, I've got two commander FDAI breakers in, AC and DC, and the two GASTA breakers in AC and DC. And next you'll want the RCS heaters all on with the - pressurize the RCS and then the MAIN SOVs open. And I think they're already open.
582250And Freddo, get the TCA breakers in last, please.
582300Alright, Jim. I'm holding off on those until you give me further word anyway. I'm just going to pressurize right now.
582308Jack, are you reading LM gimbal angles?
582416Okay, Aquarius. I have some gyro torquing angles and the Odyssey is powered down, attitude-control-wise, so LM's got attitude control now.
582524Okay. We want you to know that we've got some gyro torquing angles for you. And we want you to tell us when you've got attitude control in the LM.
582538Okay. We're still working on the pressurization. I'm getting Jim on the horn here so he can help out there.
582614We got to get this pressurized.
582658Standby 1, Aquarius. Odyssey, we'd like you to go DIRECT RCS and hold your present attitude out the window until the LM gets RCS powered up. Go ahead, Jim.
582712Well, that's my question. We're not - our 16 20 doesn't match our eight-ball here. We went FDAIs ON, but we don't have our balls completely powered up. There may be a bellyband to get our - the angles don't look the same and we don't want to go into gimbal lock.
- Essentially, Lovell is explaining that with the present configuration they don't have a lot of confidence in even being able to monitor where gimbal lock would be.
582730Roger. How far are you from RCS power up - RCS pressurization?
582744Okay, Jack. I'm right up to where it's MASTER ARM ON; RCS FIRE; both LOGIC POWERs out, that isn't closing the normal circuit breakers. You didn't have me do that. Do you want A in and then I'll fire them?
582800Okay 13, you're both talking at once. One at a time, please.
582812Close LOGIC POWER A and B, Fred, and pressurize RCS.
582829Okay, I'm going to try to do the best I can. I've got one attitude reference: I'm going to fly according to the lunar terminator.
- He can fly by sight using the shadow on the Moon as a reference.
582837Roger, Jack. Just maintain attitude.
582905What am I doing? I can't do that anyway. Let's see - crossfeed. Nose up. Down. And - -
582925Aquarius, Houston. We'll have to get some AC up so you can get a ball reading. Close your BUS TIE INVERTER circuit breakers, all four of them on panel 11. Close your AC BUS VOLT circuit breaker on panel 11. On panel 16, INVERTER 2, CLOSE. Select INVERTER 2. Over.
582950That's been completed, Jack.
582959Okay, the RCS is pressurized now.
583040Okay, Jack. Do you want us to proceed right on down the line with the RCS checkout and Activation 37 now?
583103Hell, is he still firing up there?
583116Okay, Fred. Negative on the Activation on page 37. We want your RCS pressurized and then get your TCA breakers in and go to PGNS ATTITUDE HOLD.
583154Okay, Jack, how do you read?
583157Okay, this is Houston. We want you to load the DAP with 30120.
583207Load the DAP with 30120.
583217Okay, we need to change that CSM weight.
583225Okay, Aquarius. Your CSM weight is 63400.
583252And Jack's alive to take control of the LM to stay away from gimbal lock. Over.
583259Affirmative. Take control of the LM. PGNS ATTITUDE HOLD.
583308And Odyssey, request you coordinate with Aquarius on attitude control.
583319Okay, let's see if we can fire these things, or if we have - ATT HOLD?
583327Are you firing anything?
583405And Aquarius, check your ATCA (PGNS) breaker on panel 11 IN.
583415Close, on panel 11, circuit breaker ATCA (PGNS).
583421ATCA (PGNS). Come on, let's take it easy now.
583430Okay, we've got ATCA (PGNS) closed.
583522Okay, Jim. How's the attitude control?
583528Okay, Jack. We've got attitude control now in the LM. We're going to try to rotate up through the bellyband.
583559Odyssey, Houston. I've got a procedure for you.
583609Well, I want to go up this way to get away from that -
583615The radio's all powered up.
583637Okay, Jack. Odyssey is ready to copy.
583641Okay, Jack. What we want you to do is close the reactants valve on FUEL CELL 2. Power down your inverters. Power down your battery relay bus. Battery ties off. And pull your entry circuit breakers - entry battery circuit breakers A, B, and C.
583716Check the control, and make sure we don't go to gimbal lock, Fred.
583721Okay, Jack. Understand. Close REAC valve circuit breakers in FUEL CELL 2. Power down inverters. Power down BAT relay bus. BAT TIES OFF. Power entry and both running circuit breakers A, B, and C. All off.
583741That's affirmative, Jack, and - close the reactant valve on FUEL CELL 2, there.
583751Okay. I can do that, and Jack will do the rest.
583802Okay, Jack. On FUEL CELL 2, open-circuit it.
583818Okay, FUEL CELL 2 is open-circuited. Do you want me to go through the standard shutdown procedure for the REAC valves and -
583837Odyssey, Houston. All you have to do is close the REACs valve on FUEL CELL 2.
583846Okay. CB REACs and vent REAC valves all closed.
584013Okay, Odyssey is completely powered down now according to the procedure that you read to Jack.
584022Roger, we copy. That's where we want to be, Jim.
584037And Jack, have you all got good LM data down there now?
584048That's affirmative, Fred. We're getting good LM data.
584053Okay. In that case, I think I'll pull out some display breakers and just let you all keep an eye on things.
584104He's turning his lights off now, too.
584106Standby 1 on that, Fred.
584242We don't want to lose COMM with him.
584353Aquarius, Houston. Standby on opening your circuit breakers for displays. We're going to let you know what they are, and I have some gyro torquing angles for you.
584409Okay. What page is that gyro torquing?
584412Okay, what page is the, do we write the gyro torquing angles on, Jack?
584419Okay. We're there now, Jim. Jim's got it. Go ahead with the gyro torquing angles.
584424Okay. We'd like you to proceed with the fine align and your gyro torquing angles are X +003.30, Y +024.80, Z -015.10. Over.
584448Okay, I read the gyro torquing angles as +003.30, Y is +023 - I only have four numbers for Y, you'll have to give that one to me again - and Z is -015.10. Read Y again, please.
584506Okay, Jim. X and Z are correct, and Y is +024.80.
584520Okay. We read Y as +024.80. We'll proceed on Activation 40 to fine align the platform.
584538Okay, Aquarius, proceed as on page 40 with the IMU fine align.
584702Okay, the way to do that -
584742Aquarius, Houston. Can you see any stars out the LM window?
584754We'll have to wipe them off, Jack. They're coated with water right now.
584802Roger. As soon as you get a chance to - or in a position to - take a look, we'd like to know if you can see stars for alignment purposes.
584816Okay. Jim's going to be in trouble in our present attitude out his side.
584836What have you got? How much you got left in battery A? Okay. I wish I knew what the hell they were thinking. Right now -
584851They're talking about powering down and doing a P51 here?
584857No, they were just thinking about P52 and going through the -
584901Aquarius, Houston, negative on the P51. We want to stay just like we are, but we'd like to be able to correlate what you're doing with some simulator work we're going to crank up. And so if you can give us information as to what stars you can see out the window, we can make that correlation.
584923Would you say that one more time? Give me the top tier - the top tier.
584934Jim, what we want you to do is go with your current fine align and disregard the P51. What we're attempting to do is to crank up some LMS simulations to correlate what we can get out your window with what we can get out the LMS window to see if that will help us any. So when you can see some stars, if you can - you think you can recognize them and recognize constellations, please let us know.
585003Okay, we'll check. Standby.
585213Aquarius, Houston. We notice that the Oâ‚‚ pressure in ASCENT TANK Oâ‚‚ is a little high, so we want to use some of it. So close DESCENT Oâ‚‚ and open ASCENT Oâ‚‚ TANK 2. Over.
585246Okay, Jack. Switched, now I'm on ASCENT number 2 Oâ‚‚ tank. DESCENT Oâ‚‚ is closed.
585401Okay. Houston, Aquarius. How do you read?
585405Reading you five square, Jim. Go ahead.
585410Okay. I'm looking out of Fred's window. I see a lot of particles out there, but a lot of that stuff is still drifting away from us; so a lot of it is flashing in the local vicinity, and I don't recognize any constellations right now in this particular attitude.
585435Okay, Jim. If that status changes, please let us know.
585445Roger. We're continuing to drift.
585448Okay, use your TTCAs to roll.
585509And Aquarius, Houston, I've got some circuit breakers you can open to power down displays. In addition, I have a P30 maneuver PAD. Over.
585520Roger. Standby. Get the CS - get the PAD book.
585528Get the LM data - get the LM - book.
585532And, say - we're getting the PAD book now, Jack - and say the first power down?
585538Okay, I have some circuit breakers that you can open up in order to power down displays.
585545Okay. Standby 1, Jack. I'm going to get my COMM carrier on.
585551No, no, no, Get the - get the Command Module PAD book - alright, tell you what, get all the LM stuff. Give me the LM stuff right now. Jack, give me the LM stuff.
585711Hey, what do you need out of here?
585713Can you give us the ?? data?
585822Looks like I'm cross-coupling here. I might as well -
585830Well, I want to get out of this roll.
585952Hello Houston, Aquarius.
590004Aquarius, Houston. You're -
- watching your middle gimbal there, aren't you? Go ahead, Aquarius.
590013Okay. Go ahead with the breakers first, Jack.
590015Okay. You watching your middle gimbal there?
590024Your attitude is just straight pitch down, Jim.
590033Okay, you're moving away.
590049Okay, Fred. I've got 6 circuit breakers for you.
590057Okay, they're all on panel 11. Row 1, under AC BUS B, open HELIUM PQGS for PROPELLANT DISPLAY.
590108On row 2. FLIGHT DISPLAYS, open THRUST, open MISSION TIMER, open RNG/RNG RT/ALT/ALT RT, and open the AC BUS A RNG/RNG RT/ALT/ALT RT.
590127Okay. On row 4, PGNS, SIGNAL STRENGTH DISPLAY.
590142Okay, that concludes the power down of displays. And I have a P30 PAD for you.
590157Okay, the purpose is a pericynthion plus 2 hours DPS abort. NOUN 33: 079:25:26.48. +1633.0, -0014.5, -0751.5. Apogee not applicable, perigee is +0020.5, 1797.7, 8:35. 268, 264. +1641.0, -0014.5, -0733.8. COAS is N/A.
- NOUN 33: time of burn
- NOUN 81: change in velocity X, Y, Z (∆V in feet/sec)
- NOUN 42: apogee, perigee, total ∆V
- Burn duration
- FDAI roll and pitch
- NOUN 86: change in velocity (∆V in feet/sec) in the AGS coordinate space
590319And I have two gimbal trim angles for you which will be updated. Right now, however, we want you to go with pitch 5.86, roll 6.75. Over.
590340Pitch and yaw, maybe, huh?
590342Okay. What was the last two this you gave me, a pitch and roll angle for what?
590348That's for your DPS trim.
590349Those were gimbal angles for - pitch and yaw.
590357Yeah, that's what I mean. Sorry.
590358Pericynthion plus 2. Okay, DPS pericynthion plus 2, at 079:25:026.48. +1633.0, -0114.5, -0751.5. HA N/A, HP +0020.5, 1797.7. 8:35. 268, 264. +1641.0, -0014.5, -0733.8 -
590442Did we lose water in the -
590444N/A on the COAS, and you gave me GDA angles of: pitch 5.86, and you want roll 6.75.
590500Yes, lose - get all the little bags you can with water.
590507Aquarius, Houston. Say again, please.
590513Okay, we didn't answer back there, Jack.
590516Check to see if you're on VOX.
590522Neither am I. Okay.
- Clearly at least one of them is indeed on VOX.
590530Why the hell are we maneuvering at all now? Are we still venting?
590534Well, we're ATT HOLD for one thing - I mean, we're at MIN IMPULSE.
590539No, I mean why can't you null them out somewhere?
590542Every time I try to - I can't take that doggone roll out. I got to wait until we get around to the bellyband.
590550Wait a minute. Do you - you fight roll by using the TTCA left/right. That's what you need to play with.
590605Okay, we'll try that. Let me get around though. Let's roll. Let it roll all the way.
590611Yeah, you can't let it roll all the way!
590613I know. I know. But I mean -
590616Okay, until it's upside down at least, huh?
590623Well, should I ask him what the return time on that one is? Or are you interested?
590631Let's get the first things first.
590643Oh, you don't want to hear. Let me figure some times out, here. That's at 79, and what are we at now? About - do we - do we - we don't even have computer time, do we? Nope.
590700Hey, Jack? Do you still have a mission timer? You don't? Okay.
590707Okay, let's ask - let's ask Houston to give us a mission timer - computer time. They can uplink it to us. Yeah, hold it.
590726You know, we don't have a - I don't think we have a computer clock going, and why don't you uplink that stuff to us?
590741And Freddo, I got some fast circuit breakers on panel 16 for you.
590751Okay. On row 1 under FLIGHT DISPLAYS, SYSTEM ENGINEER X-POINTER, OPEN. Under RCS B -
590802Open the TEMP/PRESS DISPLAY FLAGS and PQGS/DISPLAYS.
590810Okay. They're both OPEN.
590812Okay, Fred. On row 3 under COMM, open DISPLAYS and under ECS, open DISPLAYS.
590825Okay. COMM DISPLAYS, ECS DISPLAYS - both OPEN.
590828Okay, and two more. In row 4 under HEATERS, open DISPLAYS and under EPS, open DISPLAYS.
590840Okay. HEADERS DISPLAY, EPS DISPLAY OPEN. And I've long since had all the lights off; floods, etc.
590855Where are those bags? Where are those bags for weighing water in the PLSS?
590903We're going to fill up command module water.
590909Hell, do you need a QD -
590914- Jim. No way to get ours in there, I don't think.
590945I wonder if one of our water - jet is - okay, let's control -
590957What else can we fill up there?
591001Aquarius, Houston. We're not going to be able to uplink your time because of the IU, and we have a frequency problem there. But what I'd like to do is give you a time to set up on your mission timer and give you a mark and then you can put it into the DSKY from there. Over.
591027Wait a minute. Why do we need a mission timer right now, anyway? I mean, that bad - they'd tell us.
591032Well, I'd rather have a timer going so that we - then we can put it in the DSKY. Then we shut down the mission timer.
591037Oh, is that what you want to do?
591047Switch them. Okay, let's fire up the mission timer.
- Lovell is a step ahead of mission control here; the antenna gets switched before the request makes it up.
591059Aquarius, Houston, we need FORWARD OMNI.
591120Okay, Houston. If that call was an OMNI switch, I'm in FORWARD now.
591129Okay, Freddo. how do I get the mission timer up? Gotta get the mission timer cranked in.
591135I got the mission timer circuit breaker in.
591138Okay, we're going to probably need NUMERICS LIGHTING. There you go, you got it.
591147Aquarius, Houston. I think we've got a better way of getting your mission time up.
591200Okay, we can do a VERB 55, ENTER. And then put in R1 -00088. In R2 -00059. R3 -03274.
- This works because Houston knows when the computer was turned on, and therefore the time it is counting up from. All that is needed is to add the mission time elapsed prior to power-on; ENTER may be pressed at any time.
591228Watch the crappin' attitude.
591237God damn; I wish you'd get to something I know.
591241Well, as soon as you get over here, we'll stop it with the TTCA.
591246And Aquarius, Houston. We've got you both on VOX.
- Perhaps the salty language motivated CAPCOM on this item.
591256You want us on VOX, Jack?
591258We have you on VOX. We're reading you loud and clear and the clock took good.
591318Okay. Looks like we're on the FDA route there, Jack.
591339Okay, Jack. How do you read me on NORMAL VOICE now?
591342Hearing you 5 square, Fred.
591412And Aquarius, we're ready for a VERB 74 when you can give it to us.
591425Okay. And one other thing we noticed: when you pressurized the RCS, we got an increase in pressure in the ascent tanks, and so we want to have you verify that the ascent feeds are closed. In order to do that, on panel 11, close the ASCENT FEED 1 and 2 circuit breakers - and cycle the Parker valves, and then open the ASCENT FEED circuit breakers on panel 11.
591753And Jack, Aquarius. What kind of return time does this maneuver give us?
591802That puts you back in the water at 133 hours.
591824And that's an Atlantic landing site.
591836Affirmative. That's the PAD we've given you, but we may change our minds later on. We want you to have this info for now. And that's the minimum -
592009Aquarius, Houston. We've got to change the REFSMMAT to the one to which you're aligned. So we'd like to have P00 and DATA and we'll ship that up to you.
592122Aquarius, could you give us DATA, please?
592133He's got the updata link - the DUA breaker may not be in, Jack.
592144Okay, Fred, and close the DUA breaker.
592154Okay, Jim, and it's coming up now. Thank you.
592804Aquarius, Houston. We're finished with the uplink. The computer's yours. We'd like to power down the DUA, so pull the DUA circuit breaker please.
592814Okay. Updata link breaker's coming OPEN.
593625Aquarius, Houston. We'd like to have AFT OMNI, and we're going to lose contact with you for about a minute here while we try to establish tracking. And our latest data shows that your closest approach to the Moon is going to be 60 miles perigee, over.
593644Okay. Closest approach, 60 miles, and I'm sitting on AFT OMNI now.
593650Roger, we'll probably be going off the air here for about a minute.
593918<< A phone conversation is caught here between CAPCOM and Warren North, Chief of Flight Crew Support, coördinating work with the astronauts and engineers working in the simulators on the ground to support the crew. >>
594112Houston, Aquarius. Over.
594119Okay, we're thinking of rigging up the urine dump to the side hatch.
594129We're thinking about rigging up the urine dump to the side hatch to save urine heater power. What do you think?
594142Or better still so we can - won't freeze up our urine dump.
594148Roger, that sounds like a good plan, Jim. Why don't you go ahead with that one?
594259Okay, Aquarius. Down here we're getting regrouped, trying to work on your control modes and trying to set up something for PTC and taking a look at consumables as opposed to flight plan, and so forth. And as soon as we get all that information, we'll pass it up to you. We also have the 14 backup crew over in the simulators looking at docked burns and also trying to see what kind of alignment procedures they can come up with for looking at stars out the window. So if you ever are able to see any stars out there and think you can do an alignment out the window, why let us know.
594340Okay, Jack. Right now we're not able to. The sunlight's reflecting off the thrusters and whatever debris came away at the time of the mishap is still with us, such that the stars are hard to find. And why - what respect do you want us to do the stars out the window - just to check the LMS run, is that correct?
594404That's affirm. We'd like to correlate what information we get with yours, so that if we can use it to update the platform, we can.
594422What we're really trying to do, Jim, is see if we can do a COAS align so we can power down the platform.
594525Houston, Aquarius. We're getting an awful lot of static on the uplink now, and we're not reading you at all.
594539I have good signal strength and I'm on AFT OMNI.
594551How do you read now, Aquarius?
594706Hey, Jim, do you suppose that you could orient the LM so that the Service Module would be between you and the Sun? I believe you could see - recognize constellations out your front windows then.
- This is (yet another NASA legend) John Young passing up advice learned on Apollo 10.
594747Aquarius, Houston. Radio check.
594814Okay, Jack. How do you read now?
594817Okay, hearing you 5 square now, Jim. And the question we have is: is there some way you can orient the spacecraft so that the Service Module is between the LM and the Sun so you can recognize constellations out the window? And secondly, can you see anything out the AOT?
594928Aquarius, Houston. How do you read?
595346Aquarius, how are you reading me now?
595656Aquarius, Houston. How do you read?
595708Aquarius, request FORWARD OMNI, please.
595822Aquarius, Houston. Request FORWARD OMNI. How do you read?
595906Okay, Houston, Aquarius. How do you read?
595908Hello there, Aquarius. Loud and clear. How do you read me?
595914There's an awful lot of background -
595915Okay, we've got a lot of background static, Jack. You're down in the mud. You having a ground problem?
595923What we tried to do was to get the IU frequency shifted off a little bit so that we'd have less interference. I think it'll come up - what we want you to do is turn on your descent oxygen and turn off your ascent oxygen. Over.
595938And request FORWARD OMNI.
595943You're unreadable, Jack. We've got our signal strength meter - right now it keeps wavering up and down. The best I'm getting is about 2.4 AGC.
- Apparently, the crew have popped back in their COMM DISPLAY breaker to resolve the COMM issue, which means -
595953Roger. Request FORWARD OMNI.
595958I am on FORWARD OMNI. I've been on FORWARD OMNI.
- - that they already knew to be on FORWARD OMNI. This in turn means that INCO's diagnosis of the problem wasn't quite right.
600044Okay, how do you read, Jack?
600046I'm hearing you 5 square, Fred. How me?
600113Aquarius, Houston. How do you read?
600203Aquarius, Houston. Radio check.
600210Okay, every time you transmit, Jack, the AGC starts to drop off and the static level cranks up.
600218Okay, Fred. You're loud and clear.
600230Fred, go to DESCENT Oâ‚‚.
600405Hello Houston, Aquarius.
600408Hello there, Aquarius. How do you read me now?
600423Hello Houston, Aquarius.
600431Okay. That's the first clear word we've heard from you, Jack. Do you think it could be my pitch attitude that's breaking up your incoming? I guess you've been hearing us.
600442We have been hearing you, and the problem is on the ground. I hope we have it corrected now.
600453We're considering powering down the PGNS but we want to know what capability you have to do a coarse and fine align. And we read your conversation about being unable to see out the window very good. How about out the AOT?
600530Okay, and the other thing we thought you might try is to put the Service Module between you and the Sun, and then to see if you can see anything out the window in that attitude.
600543The reason that we think that that would work is that it worked on Apollo 10. It made the constellations all recognizable when we put the Service Module - in our case the LM, between us and the Sun.
- Once again, this is Apollo 10 CMP John Young.
600606You're down in the mud again, Jack. And it appears that some other circuit is feeding through on there with you.
- Enough so that Fred couldn't even tell that it wasn't Jack speaking.
600729Okay, you're down in the mud again, Jack. Lots of background static.
601118Okay. Houston, Aquarius. How do you read?
601821Aquarius, Houston. How do you read?
602246Hello Houston, Aquarius. How do you read?
602249Hello there, Aquarius. Loud and clear. How me, now?
602254Okay, we're reading you loud and clear, Jack. I hope it stays this time.
602258Okay. We'd like to brief you on what our plan is. We're, at this time, water critical in the LM. So we'd like to use as little as possible. To do this, we're going to plan to make a free-return maneuver of 16 feet per second at 61 hours, which is 37 minutes from now. Then we're going to power down the PGNS, and then we'll - at 79 hours, we'll go ahead and make another abort maneuver to kick what we've got. But we'd like to get that PGNS powered down as soon as possible.
602339That would be after the midcourse and - so, how do you feel about making a 16 foot-per-second burn in 37 minutes?
602349Well we'll give it a try, Jack, if that's all we've got. That's a 16 foot-per-second DPS burn in 37 minutes?
602357Roger. We're working up a PAD for it, but we want to know what you think about doing it at that time.
602408Well, we'll do it. Could you give us a little bit more time?
602431Okay, Jim. We'd like to get a suggested time from you. We can figure out a free-return maneuver for any time you want to give us, so if you'll give us the time you'd like to shoot for, we'll figure out a PAD.
602447Okay, that sounds good. I think if we have a little bit more time - we want to do it right. Standby 1.
602504Let's shoot for an hour if we can, Jack. How's that?
- Prepping for a midcourse burn was normally scheduled for around 75 minutes, and that's with the ready-to-go SM SPS. The LM DPS normally took 2 hours to activate, so even an hour is rather compressed.
602515Okay, Jim. How about 61 hours and 30 minutes? That's an hour and 5 from now.
602524Okay. We'll do it and we want to be sure we talk back and forth, now, to make sure we get this burn off right.
602535Okay. In the interim, Jack, I looked around again and I saw that we have a radar and a landing radar heater breaker in. Can I pull those out?
- CONTROL noticed these around 58:02 and 58:11, but the instruction never made it up to pull them.
602546Affirmative. Pull them both out.
602552And now we want to ask you a question about alignments and so forth: we wanted to know if you can see any stars out of the AOT. We also wanted to know if you could use the Service Module to cast a shadow on the LM windows and then look out the windows to see stars for a P51 COAS alignment.
602614Okay, in this attitude, Jack, that we're pitching around, I cannot use the AOT to see stars. We - we're just not able to see them at all. Now, we may be able to maneuver off in yaw or - and/or roll, and see stars. Right now, we haven't been able to. The AOT is useless. The Command Module structure is just radiating too much light into the - into the telescope.
602641Okay. And how about using the Service Module to cast a shadow on the Commander's window? If you do that, can you see stars for a COAS alignment?
602655We could give that a try, Jack, although I don't know how successful it will be. We tried to do it; the light shines off our quads which makes it difficult to see stars. We do have the Earth and Moon, if that can be of assistance.
602718Another problem: right now, Jack, I'm looking out the right window and it's pretty dark out that window but there are about a thousand or so false stars out here from - left over from some of the debris. It's hard to discern what's real and not real.
602739Okay. That's good information. And during the time that we see you're continuing to pitch, if you ever get in a position where you think the AOT might be of some use, we'd like you to periodically look out of it and see if you can see some stars that would enable us to get a P52.
602759Okay, will do. And also, let me ask you a question: in this configuration, docked, we have to use the TTCA to control pitch and roll. And just how much can we use that without really changing our trajectory? We only have 60 miles to play with.
- Lovell is concerned, because with the weight of the CSM attached to the LM the controls normally used to rotate the spacecraft don't do much (imagine twiddling a long stick between two fingers at its middle as opposed to at its ends), so he has to use the controls normally used to shift the spacecraft in space (now imagine flicking it in one direction at one end). But this has the potential to alter the trajectory of the spacecraft, and this close to the Moon very small adjustments can turn into miles of difference at the very far point.
602822Roger. We'll put that to them.
602845Okay, Jack. Are you ready to go to work with me on the 2-hour DPS activation and contingency book, page 1?
- If anybody has this activation checklist, please send it our way!
602855Roger. We're ready to go.
602905Okay, item 1 we can - 1 through 5 we can scratch off as done. Is that correct?
603019Okay, Fred. Let's go ahead. Step 1, page 1. Everybody's listening.
603028Okay. I've looked around, and I've essentially done steps 1 through 5 with the exception of floodlights and utility lights, and I think we'll just do without those.
603047Okay. On EPS activation, we're through step - we're through that - bottom of that page. That's all done.
603113Okay, in essence, we've circumvented step 4, and we're not sitting with all 4 acs - descent BATs on high voltage taps, so I'll scratch off step 4.
603128Roger, and in step 5 we want to leave INVERTER 1 circuit breaker OPEN.
603137Roger. In step 5, we'll leave INVERTER 1 CB OPEN.
603154Okay. For the time being, our mission timer is the computer. So mission timer activation - scratch off.
603210Okay. We've done the primary glycol loop activation.
603229Aquarius, we recommend you leave the caution and warning off on page 3.
603236Okay, I was going to say that next. Page 3 we'll just scratch item 1. And item 2, I've already got the RCS heaters on. And I don't know if I gave you the time or you got the time on the PRIMARY EVAP FLOW number 1 OPEN.
603310Okay. Let's go to the CB pages now.
603329Freddo, did you close the ENGINE CONTROL breaker on panel 11?
603338What control was that, Jack?
603341Did you close the S/C ENGINE CONTROL breaker on panel 11? As we got step 1 there on page 3.
- STAB/CONT; stabilization and control.
603355Okay, yes. The EPS DESCENT ECA CONTROL breaker is CLOSED on 11.
603401Roger, and how about the - on panel 11, S/C ENGINE CONTROL, CLOSED?
603420We're AFT OMNI, and we have the S/C ENGINE CONTROL breaker CLOSED.
603425Roger. Let's go on with the circuit breaker panel checkout.
603435Okay. I'll just give you - I think it'll be easier, here, to give you what I got in.
603442Okay, in the top row on 11, we have the four AC BUS TIE breakers IN and the AC BUS VOLTS breaker IN, and that's it.
603456Second row, we have the four TCA breakers IN. We have the GASTA under FLIGHT DISPLAYS and COMMANDER's FDAI. And likewise under AC BUS A, we have a GASTA and a COMMANDER FDAI breaker IN. That's it.
603517On row 3, we have a SIGNAL CONDITIONER 1. We have the ATCA (PGNS). We have the ENGINE CONTROL breaker, ATTITUDE DIRECT CONTROL breaker, and the - under LIGHTING, ANUN/DOCK/COMPONENT breaker IN. And one other: ED LOGIC POWER A - ED LOGIC POWER A is also IN.
603545Okay, under the fourth - fourth row, we got all the QUAD HEATER breakers IN. SUIT FAN 1. Under ECS, GLYCOL 1 and 2.
603602And under COMM we have COMMANDER AUDIO IN. And PGNS LGC/DSKY, IMU STANDBY, IMU OPERATE, and that's it.
603617Okay. In the bottom row: EPS, we have the BAT FEED TIE both IN, and we have the CROSS TIE BALANCE LOADS IN, the X-LUNAR BUS TIE, DESCENT ECA CONTROL, DESCENT ECA, and the DC BUS VOLTs breaker.
603639That completes it for panel 11.
603654As I see it, some of the checklist are - we need the DECA GIMBAL IN sooner or later -
603700That's affirm. Close the DECA GIMBAL.
- and probably - okay, DECA GIMBAL - and sooner or later, we're going to need DECA POWER, I guess also.
603716Alright, DECA POWER will come up later in the procedure, Freddo.
603842Aquarius, Houston. On your circuit breaker checklist, on panel 11 and 16, we want you to configure the panels as outlined in the checklist.
603858Okay. You want us to configure as per checklist. Okay, we'll do that.
603903That's right. Close the black ones and open the white ones.
603912Yeah, I think we can manage that.
603919With the Activation power-up, we're starting right now.
604012Houston, we might as well leave our RCS TCAs IN, right?
604023Affirmative, Jim. Leave your RCS TCAs in on panel 11.
604030Yeah, I just used my Pentel pen and made those white ones black ones.
604035Roger. Same on 16, Fred.
604045And you might look there, Houston, to see what circuit breakers aren't required, like the tape recorder.
604141Okay, Jim. On panel 11 over there, you can also leave open the RENDEZVOUS RADAR HEATER breaker and the LANDING RADAR HEATER breaker, in addition to the tape recorder.
604205I'm leaving a few in, Jack, too, like the SUIT FAN 1 is still IN, RCS SYSTEM is still IN, the TCAs.
604213ATTITUDE DIRECT CONTROL is IN.
604233How about if I leave the VHF A and B OFF?
604241I switched to FORWARD OMNI.
604252Okay, we can leave the VHF powered down too.
604301And do you want the SECONDARY S-BAND?
604305Negative on SECONDARY S-BAND. Leave them open.
604314UP DATA LINK is IN. Do you want that in or out?
604322Leave the UP DATA LINK OPEN. We'll call for it when you want to put it in.
604437Okay, Jack. On panel 11 on the top row, do you really want the PROPULSION PQGS and ASCENT HELIUM REGs IN?
604454And also the SYSTEM ENGINEER X-POINTER breaker.
604459Roger. Negative on the PQGS. Negative on the ASCENT HELIUM REG. And negative on the X-POINTER.
604517Okay. On the second row, I'm going to leave the FLOODLIGHT breaker open.
604531And we're again up to - do you want the CWEA enabled?
604602Okay, since we're - are we going to power up the AGS or should I concern myself with the ATCA breaker?
604619However, Fred, we need the ATCA breaker IN.
604629Okay, ATCA breaker's IN.
604635Yeah - I guess for the backup power supply.
604641Okay, how about ATCA AGS?
604706And I'm leaving the SUIT FLOW CONTROL breaker OPEN.
604720Let's close the SUIT FLOW CONTROL, Freddo -
604721And Jack, OMNIs going now -
- it doesn't take any current.
604730Okay. Without suits it doesn't do us much good either, though.
604752Okay, and are we going to continue to be able to operate off the OMNIs, Jack? So can I leave the S-BAND antenna powered down?
604818Okay, Freddo, we don't plan to use the steerable antenna, although we want to leave the heaters on. So it looks like you ought to open up COMM S-BAND ANTENNA, but leave S-BAND ANTENNA HEATERS closed.
604833Roger. COMM S-BAND is OPEN, S-BAND HEATER breaker is still CLOSED.
604927And on the bottom row, Jack, I'm going to leave the HEATER DISPLAY breaker out, which we had pulled before, and EPS DISPLAY. But I question: do we want the ASCENT ECA breaker in, as prescribed?
604951That's a negative on the ASCENT ECA breaker, leave it OPEN.
605002And Aquarius, we need P00 and DATA -
- and we'll give you a state vector and target load.
605012Okay. We need the UP LINK breaker in, then, now.
605023Okay. And Jack, will you give us that - how about the ORDEAL breaker? Can I pull that? We don't need that, do we?
605032Negative on the ORDEAL. Leave it OPEN.
605048And how about the ASCENT ECA breaker on panel 11? Jim has it in over there.
605102And on panel 11, ASCENT ECA can be OPEN.
605127Okay, Aquarius. We're GO on the circuit breaker configuration as you have it now.
605204And Aquarius, tests in the simulator just showed that if you want to let the PGNS DAP hold your attitude for you, it will.
605230And Jack, because it will take quite a while to get back to the attitude, I think we ought to think about going there very shortly.
605238Roger. I have a PAD for you.
605242I have a P30 maneuver PAD.
605259Okay, they want you to hold your maneuver until we finish making the LOAD. We haven't completed it yet. Are you ready to copy P30 maneuver PAD?
605309Okay, here we go. The purpose is midcourse correction for free-return. NOUN 33: 061:29:42.84. -0021.3, +0004.1, -0031.2. HA and HP are N/A, ∆V 0038.0. 0:31. 120, 298. -0021.3, +0004.1, -0031.2. COAS N/A. And I have your LM GDA angles: pitch 5.86, roll 6.75. Your DPS throttling: 5 seconds at 10%, burn the rest at 40%. Your ullage will be 2 jets for 10 seconds.
- NOUN 33: time of burn
- NOUN 81: change in velocity (∆V in fps)
- NOUN 42: apogee, perigee, total ∆V
- Burn duration
- FDAI roll and pitch
- NOUN 86: change in velocity (∆V in fps) in the AGS coordinate space
605457Okay, Jack. We have a P30 maneuver PAD, a midcourse for free-return. NOUN 33: 061:29:42.84. -0021.3, +004.1, -0031.2. HA and HP N/A, ∆VR 0038.0. 0:31. 120, 298. -0021.3, +0004.1, -0031.2. COAS N/A. GDA angles, pitch 5.86, roll 6.75. DPS throttle 5 seconds at 10%, burn the rest at 40%. And we need a 2-jet, 10 second ullage.
605602That's a good readback, Fred. I'd like to verify, however, in NOUN 81 in VY, it's plus three balls 41.
605615Okay. NOUN 81, VY is +0004.1.
605621Good readback. Let's press on with the checklist.
605628Okay. And Jack, find out about using TTCA to maneuver with.
605632Okay. We're finished with the computer, it's yours. And we recommend using the TTCA to maneuver with.
605643Okay, I'm back on the checklist, page 6, Jack. Under PGNS turn-on and self-test, we've done everything except the self-test here on this page. Do you want to do that at this time?
605729Okay, Aquarius. Negative on the PGNS self-test. Page 7.
605737Okay. I'll scratch page 6. And on page 7, we're not going to activate the - or rather, we've had the S-BAND activated, ECS Activation I have all done. And at the bottom of the page, the docked IMU coarse align is done.
605815We've - okay, we've also completed, I guess in essence, all of page 8.
605822That's affirmative, and page 9 to boot. Scratch VHF; we've done the T-ephems.
605836Okay, you've updated it, that's right. We cranked in the time.
605852And Houston, let's go to Activation - or get into page 10 and see what we do there.
605858Okay. The only item on page 10 is to deploy the landing gear.
605906Okay. We'll do that now.
610009Okay. The landing gear are down and locked, Jack, and looking ahead now at page 11, we've done all of that.
610024We verify that. Page 12.
610031Okay, and I assume in amongst all those numbers you pumped up, we got a REFSMMAT and STATE VECTOR, is that correct?
610038That's affirmative. You've got that, so you can delete page 12.
610051Okay, on 13, you've read us up the fine align angles and we've cranked those in.
610108Okay, so now we're up to - we've got to do the DAP set, the gimbal/throttle test.
610120Okay, Aquarius. We recommend omitting the DAP set, gimbal/throttle test. Just make sure the gimbal - DECA POWER and DECA GIMBAL circuit breakers are closed.
610133Okay. We're going to proceed now with the DAP set, gimbal/throttle test, is that correct? Or did you say delete it?
610140Aquarius, delete the DAP set, gimbal/throttle test. Just ensure that the DECA POWER and the DECA GIMBAL are closed.
610149Okay, Houston. DECA POWER is OPEN at this time. Do you want me to close it?
610155Affirmative, Jim. Close the DECA POWER.
610200It's CLOSED. We deleted that.
610227Okay. Also out of that list, Jack, we need the COMMANDER'S THROTTLE set to THROTTLE and MIN.
610300if I recall the launch set of the gimbals, the GDAs are not correct here, and where are we going to get those set for the burn?
610333Okay, here's the word on the DAP set, gimbal/throttle test. Let's do step 1 and step 2, and that'll get our gimbal set.
610420Okay, Jack. We're going to have to back up on this if we're going to follow the procedure here, which has us go MODE CONTROL PGNS AUTO. We're going to have to pull the TCA breakers to keep from firing jets.
610529Standby on step 1, Fred. We're getting the word for you.
610534How do you like this sim?
- Though many emergency scenarios were rigorously simulated and trained for by a simulation team that prided themselves on putting everybody through the wringer, many of the failure modes on Apollo 13 were never simulated or planned for as it was assumed the vehicle would simply be an immediate catastrophic loss.
610610Okay, Aquarius, we recommend you do the DAP set and gimbal/throttle test as per the checklist. Go PGNS AUTO and proceed.
610621Well, we're going to fire our thrusters as soon as we go to AUTO because we've got those thrusters in - the thruster circuit breakers. Do you want us to do that and stop?
610651Okay, Aquarius, we're recommending you go to AUTO, let the thrusters fire and settle down, and proceed with the test.
610709Roger. Your DAP is set, you're in wide deadband; that ought to do the trick.
610720Okay, we're looking at it, Aquarius; we're ready to proceed with the test.
610752Okay, and Houston, you -
610755- you're looking at the weights now. Those are still good, right?
610801You're GO on the weights.
610906Aquarius, Houston. We'd like you to recycle on the DAP load and change your DAP to 32021. Over.
611106Okay, Aquarius. We're looking at your gimbal and we notice that we've got a 4-jet ullage loaded in the DAP and we gave you 2 jets on the PAD. But let's go with what we've got loaded. It'll be a 4-jet ullage.
611141Okay, Houston. How does the GDAs look now?
611145The GDAs are GO as they are. Press on.
611209Okay, Houston. We're going to do the DPS pressurization and checkout.
611235Okay, your gimbals are within 0.3 and we're ready for the DPS pressurization and checkout.
611334Okay, Houston. Do you want to follow up on page 15 with RCS checkout? In essence, we've kind of already done that.
611347You're right, Aquarius. Let's delete the RCS checkout.
611543Houston, we're going to do a PGNS AUTO maneuver to the attitude.
611554Aquarius, we recommend driving it around there manually with a TTCA.
611559Okay, we have to use the TTCA. Roger.
612110We're going to AUTO now, Houston, to try to damp the rates. We're at the attitude.
612123Roger, Jim. We verify the attitude.
612337And Houston, we'd like to confirm: do you want the VERB 65 ENTER in there?
612345Affirmative on the VERB 65.
612412Okay, Jack. I've got another question on page 18. At 1 minute, I concur with MASTER ARM ON, but I wonder why I have to have the ABORT STAGE breaker in.
612427We sure don't want any staging now.
- This would drop the descent stage of the LM, which they need for getting home, as in addition to the better engine it contained consumables.
612438Aquarius, delete the ABORT STAGE circuit breaker CLOSE. Leave it OPEN.
612456Okay. Also, Jack, since we have 4-jet ullage versus 2, do you want - still want 10 seconds ullage or do you want 5 now?
612509Okay, Aquarius, we'll use automatic ullage.
612518Okay. We'll just let the 7.5 second AUTO ullage do it.
612523Roger, and we'd like to do this in manual throttle, so on page 17 about two-thirds of the way down, THROTTLE CONTROL, MANUAL - vice AUTO.
612535Okay. We're set to MANUAL.
612611We've got 203 on the DSKY now and it looks as though it requires work. Can we pass it?
612616Aquarius, ENTER on the 203.
612652Aquarius, we'd like to verify that your throttle is in the MIN position.
612700And in the event that you have to do a manual takeover, turn the ENGINE GIMBAL OFF, MODE CONTROL to ATTITUDE HOLD, and use the hand contr - use the TTCA.
612846Okay. MASTER ARM's ON. 1 minute.
612853Roger, Aquarius. You're GO for the burn.
613004Okay, Aquarius. You're looking good.
613040Okay, you're looking at 16 85 now, Jack.
613047Okay, you're GO on the residuals; proceed.
613055Okay, when you say GO on the residuals, you mean don't trim them. Is that right?
613100That's affirmative. No trim required.
613218Aquarius, check your MASTER ARM OFF, please.
613245Okay, Houston. Burn's complete. Now we have to talk about powerdown, and what you want us to do with the PGNS.
613253Roger. We're looking at that right now, and you'll be the first one to get the word.
613319And Houston, it's doubtful right now whether we'll be able to see the stars in this configuration. The only way we could possibly get alignment is with the Earth and the terminator or the Moon and its terminator and I'd sure like to have you look at a powerdown - keeping the PGNS if at all possible.
613349Roger, Jim. We'll get the word for you.
613525And Houston, we're in an ATT HOLD mode. Can we turn off the thrusters?
613541Standby on that one, Jim.
613814Okay, Aquarius. We're working on what's going to happen next. In the meantime, we'd like to take some high-power items off the line; so on panel 11, open DECA POWER and open DECA GIMBAL. On 16, open the ATCA breaker.
613836Okay. On 11, we've got DECA POWER, DECA GIMBAL OPEN. On 16, we've got the ATCA breaker OPEN.
613938And Houston, while you're thinking, see if you can come up with a procedure of perhaps using the Command Module optics with manual drive, if I have to look for stars.
614124And Jack, Aquarius. While you're thinking - before we had our COMM problems, we were wanting to know what to - whether we should hook up the side hatch urine dump system. So we wouldn't freeze up the normal urine dump feed.
614145Roger. We gave you a GO on that earlier. Sorry, you must have missed it. Use the side hatch for urine dump.
614156And how are the stars out the window now?
614213Well, I'll look again, Jack, but at this attitude the Sun is reflecting off of - off of Quad 4 so bright that it's ruining any night vision. And we've still got particles floating around us. I'll have to take a long look and see if I can see any star patterns.
614243And Aquarius, we're going to have to hand you over to a different site now, and we think maybe things will work better if this time we turn off the S-BAND TRANSMITTER/RECEIVER, and bring it back up in 5 minutes. You copy?
614310Okay, I understand you want us to turn off the S-BAND TRANSMITTER/RECEIVER and bring it up in 5 minutes. Is that correct?
614342And you want us to maintain attitude control?
614346Affirmative on the attitude control.
614348That's AUTO attitude control. Okay. We'll maintain AUTO attitude control.
614356Okay, Jack. I'm back on the line now. On the S-BAND, you want me to turn off the TRANSMITTER/RECEIVER and the POWER AMPL to OFF for 5 minutes. Is that - when you give me the word - is that what you want?
614410Aquarius, leave the POWER AMPLIFIER the way it is. Turn the TRANSMITTER/RECEIVER OFF for 5 minutes.
614419Okay, you tell me - you tell me when.
614422Okay, turn it off now. See you in 5 minutes.
614426Okay, it's gone off. It's gone off for 5 minutes.
615244Aquarius, Houston. How do you read?
615252Okay, you're loud and clear there, Jack.
615255Roger, same here. We're all - we're still discussing the next move.
615304I figured it. Let's just make it a good one.
615318We're looking real close at water usage profiles, and right now things are kind of swinging toward leaving the IMU powered up and powering down the LGC. But we'll have more word for you shortly. And we recommend for sleeping that you leave one guy on watch. We recommend you don't make any urine dumps if you can help it, because it'll make the debris problem worse than it is now. And we have some items that you might want to transfer to the LM: some towels, some penlights, fecal bags, UTS. And do you have any more items that we can help you out with at the moment?
615417Okay. Stand by on your latter list there, Jack. I understand no urine dumps; I guess we'll work through the UCD and all the bags we got. And real quick there, can you give a DAP load that we want in here now to conserve the RCS?
615521Okay. For attitude control, we're recommending manual control VERB 76 and watch your middle gimbal angle. Your DAP load that you have now looks good.
615537Okay, it's ATT HOLD VERB 76 for the guy on watch. And the DAP load we've got right now is okay.
615818Aquarius, our decision for this time is to leave the IMU powered up, power down the LGC, and power down other nonessential items. We'll be coming up with a more precise checklist as soon as we can get it. Over.
615837Okay. The decision is to keep the platform, power down the computer, and we'll be standing by for further word on the powerdown, Jack.
615933And Aquarius, for your information, we now have a 136 mile perigee.
615947Okay, 136 mile perigee now. That's very nice.
620009Oh. Wait a minute, Jack. Did you say pericynthion or perigee?
- Closest approach to Moon.
- Closest approach to Earth.
- You can see why he'd be concerned about this.
620520And Houston, we pulled out your UPDATA LINK circuit breaker, so if you want to update it for anything, let us know and we'll put it back in.
