Apollo 13, Houston. The next thing we'd like you to do is to -
554845
CMP
Go ahead.
CAPCOM
- 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 -
554913
CMP
Okay. Will do.

CAPCOM
One 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.
554925
CMP
Okay, 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.
555005
CAPCOM
Roger. We copy, and the TV show was great.

In 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."

CAPCOM
Aquarius, Houston. I think we've got a better way of getting your mission time up.
591158

Go ahead with it.
591200
CAPCOM
Okay, 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.

Okay. 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.

CAPCOM
Roger, that sounds like a good plan, Jim. Why don't you go ahead with that one?
594301
CAPCOM
Okay, 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.
594343
CDR
Okay, 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?
594406
CAPCOM
That'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.
594424
CAPCOM
What we're really trying to do, Jim, is see if we can do a COAS align so we can power down the platform.

What 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.
595940
CAPCOM
And request FORWARD OMNI.
595946

You'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 -

Okay, we're reading you loud and clear, Jack. I hope it stays this time.
602300
CAPCOM
Okay. 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.
602340
CAPCOM
That would be after the midcourse and - so, how do you feel about making a 16 foot-per-second burn in 37 minutes?
602351
CDR
Well 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?
602359
CAPCOM
Roger. We're working up a PAD for it, but we want to know what you think about doing it at that time.
602409
CDR
Well, we'll do it. Could you give us a little bit more time?
602432
CAPCOM
Okay, 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.
602449
CDR
Okay, that sounds good. I think if we have a little bit more time - we want to do it right. Standby 1.
602506
CDR
Let'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.
602517
CAPCOM
Okay, Jim. How about 61 hours and 30 minutes? That's an hour and 5 from now.
602526
CDR
Okay. 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.
602533
CAPCOM
Affirm.
602536
LMP
Okay. 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.
602547
CAPCOM
Affirmative. Pull them both out.
602554
CAPCOM
And 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.
602616
CDR
Okay, 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.
602643
CAPCOM
Okay. 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?
602657
CDR
We 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.
602720
LMP
Another 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.
602741
CAPCOM
Okay. 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.
602800
CDR
Okay, 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 (imaging 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. 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.
602824
CAPCOM
Roger. We'll put that to them.
602847
LMP
Okay, 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!
602856
CAPCOM
Roger. We're ready to go.
602907

603042

603049

CAPCOM
We concur. Page 2.
603115

Okay, 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.
603130

LMP
Okay, 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?
604820
CAPCOM
Okay, 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.
604835
LMP
Roger. COMM S-BAND is OPEN, and S-BAND HEATER breaker is still CLOSED.
604928
LMP
And 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?
604949
CAPCOM
Standby.
604953
CAPCOM
That's a negative on the ASCENT ECA breaker, leave it OPEN.
605004
CAPCOM
And Aquarius, we need P00 and DATA -
605006
LMP
And that's a -
CAPCOM
- and we'll give you a state vector and target load.
605014
LMP
Okay. We need the UP LINK breaker in, then, now.
605019
CAPCOM
That's affirmative.
605025
CDR
Okay. And Jack, will you give us that - how about the ORDEAL breaker? Can I pull that? We don't need that, do we?
605034
CAPCOM
Negative on the ORDEAL. Leave it OPEN.
605050
LMP
And how about the ASCENT ECA breaker on panel 11? Jim has it in over there.
605103
CAPCOM
And on panel 11, ASCENT ECA can be OPEN.
605109
CDR
It's OPEN.
605129
CAPCOM
Okay, Aquarius. We're GO on the circuit breaker configuration as you have it now.
605138
LMP
Roger.
605206
CAPCOM
And Aquarius, tests in the simulator just showed that if you want to let the PGNS DAP hold your attitude for you, it will.
605218
CDR
Okay, very well.
605232
CDR
And 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.
605240
CAPCOM
Roger. I have a PAD for you.
605244
CAPCOM
I have a P30 maneuver PAD.
605251
CDR
Roger - standby.
605301
CAPCOM
Okay, 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?
605309
CDR
That's affirm.
605311
CAPCOM
Okay, 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
605459
LMP
Okay, 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.
605603
CAPCOM
That's a good readback, Fred. I'd like to verify, however, in NOUN 81 in VY, it's plus three balls 41.
605616
LMP
Okay. NOUN 81, VY is +0004.1.
605623
CAPCOM
Good readback. Let's press on with the checklist.
605629
CDR
Okay. And Jack, find out about using TTCA to maneuver with.
605634
CAPCOM
Okay. We're finished with the computer, it's yours. And we recommend using the TTCA to maneuver with.
605643
CDR
Roger.
605644
LMP
Okay, 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?
605730
CAPCOM
Okay, Aquarius. Negative on the PGNS self-test. Page 7.
605738
LMP
Okay. 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.
605805
CAPCOM
Roger.
605817
LMP
We've - okay, we've also completed, I guess in essence, all of page 8.
605823
CAPCOM
That's affirmative, and page 9 to boot. Scratch VHF; we've done the T-ephems.
605838
LMP
Okay, you've updated it, that's right. We cranked in the time.
605854
CDR
And Houston, let's go to Activation - or get into page 10 and see what we do there.
605900
CAPCOM
Okay. The only item on page 10 is to deploy the landing gear.
605907
CDR
Okay. We'll do that now.
610011
LMP
Okay. The landing gear are down and locked, Jack, and looking ahead now at page 11, we've done all of that.
610025
CAPCOM
We verify that. Page 12.
610032
LMP
Okay, and I assume in amongst all those numbers you pumped up, we got a REFSMMAT and STATE VECTOR, is that correct?
610040
CAPCOM
That's affirmative. You've got that, so you can delete page 12.
610052
LMP
Hey, on 13, you've read us up the fine align angles and we've cranked those in.
610102
CAPCOM
Affirmative.
610109
LMP
Okay, so now we're up to - we've got to do the DAP set, the gimbal/throttle test.
610114
CAPCOM
That's -
610121
CAPCOM
Okay, Aquarius. We recommend omitting the DAP set, gimbal/throttle test. Just make sure the gimbal - DECA POWER and DECA GIMBAL circuit breakers are closed.
610135
LMP
Okay. We're going to proceed now with the DAP set, gimbal/throttle test, is that correct? Or did you say delete it?
610141
CAPCOM
Aquarius, delete the DAP set, gimbal/throttle test. Just ensure that the DECA POWER and the DECA GIMBAL are closed.
610151
CDR
Okay, Houston. DECA POWER is OPEN at this time. Do you want me to close it?
610156
CAPCOM
Affirmative, Jim. Close the DECA POWER.
610201
CDR
It's CLOSED. We deleted that.
610229
LMP
Okay. Also out of that list, Jack, we need the COMMANDER'S THROTTLE set to THROTTLE and MIN.
610259
LMP
Houston -
610302
LMP
if 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?
610334
CAPCOM
Okay, 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.
610421
LMP
Okay, 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.
610453
CAPCOM
Standby, Fred.
610529
CAPCOM
Standby on step 1, Fred. We're getting the word for you.
610534
CAPCOM
How 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.
610542
CDR
It's a beauty.
610610
CAPCOM
Okay, Aquarius, we recommend you do the DAP set and gimbal/throttle test as per the checklist. Go PGNS AUTO and proceed.
610621
CDR
Well, 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?
610651
CAPCOM
Okay, Aquarius, we're recommending you go to AUTO, let the thrusters fire and settle down, and proceed with the test.
610706
CDR
We're in PGNS AUTO.
610709
CAPCOM
Roger. Your DAP is set, you're in wide deadband; that ought to do the trick.
610715
CDR
Roger.
610720
CAPCOM
Okay, we're looking at it, Aquarius; we're ready to proceed with the test.
610726
LMP
Okay, we're proceeding.
610752
LMP
Okay, and Houston, you -
610755
LMP
- you're looking at the weights now. Those are still good, right?
610801
CAPCOM
You're GO on the weights.
610906
CAPCOM
Aquarius, Houston. We'd like you to recycle on the DAP load and change your DAP to 32021. Over.
611105
CAPCOM
Okay, 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.
611118
LMP
Okay.
611141
LMP
Okay, Houston. How does the GDAs look now?
611145
CAPCOM
The GDAs are GO as they are. Press on.
611209
CDR
Okay, Houston. We're going to do the DPS pressurization and checkout.
611216
CAPCOM
Standby 1.
611234
CAPCOM
Okay, your gimbals are within 0.3 and we're ready for the DPS pressurization and checkout.
611333
LMP
Okay, Houston. Do you want to follow up on page 15 with RCS checkout? In essence, we've kind of already done that.
611347
CAPCOM
You're right, Aquarius. Let's delete the RCS checkout.
611352
CAPCOM
And the DPS looks GO.
611542
CDR
Houston, we're going to do a PGNS AUTO maneuver to the attitude.
611547
CAPCOM
Standby on that.
611553
CAPCOM
Aquarius, we recommend driving it around there manually with a TTCA.
611559
CDR
Okay, we have to use the TTCA. Roger.
612109
CDR
We're going to AUTO now, Houston, to try to damp the rates. We're at the attitude.
612121
CAPCOM
Roger, Jim. We verify the attitude.
612126
CDR
Roger.
612336
LMP
And Houston, we'd like to confirm: do you want the VERB 65 ENTER in there?
612343
CAPCOM
Affirmative on the VERB 65.
612348
LMP
Okay.
612411
LMP
Okay, 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.
612426
LMP
We 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.
612437
CAPCOM
Aquarius, delete the ABORT STAGE circuit breaker CLOSE. Leave it OPEN.
612445
LMP
Roger. Will delete.
612454
LMP
Okay. Also, Jack, since we have 4-jet ullage versus 2, do you want - still want 10 seconds ullage or do you want 5 now?
612508
CAPCOM
Okay, Aquarius, we'll use automatic ullage.
612517
LMP
Okay. We'll just let the 7.5 second AUTO ullage do it.
612522
CAPCOM
Roger, 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.
612534
LMP
Okay. We're set to MANUAL.
612557
CDR
What's the 203 -
612605
CAPCOM
ENTER on the 203, Jim.
612610
CDR
We've got 203 on the DSKY now and it looks as though it requires work. Can we pass it?
612615
CAPCOM
Aquarius, ENTER on the 203.
612621
CDR
We hit ENTER.
612650
CAPCOM
Aquarius, we'd like to verify that your throttle is in the MIN position.
612657
CDR
That's affirm.
612659
CAPCOM
And 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.
612813
LMP
Okay, 1 +30 to burn.
612820
CAPCOM
Roger.
612845
LMP
Okay. MASTER ARM's ON. 1 minute.
612852
CAPCOM
Roger, Aquarius. You're GO for the burn.
612954
CDR
40 percent.
613003
CAPCOM
Okay, Aquarius. You're looking good.
613025
CDR
AUTO SHUTDOWN.
613040
LMP
Okay, you're looking at 16 85 now, Jack.
  • VERB 16 NOUN 85
613046
CAPCOM
Okay, you're GO on the residuals; proceed.
613054
LMP
Okay, when you say GO on the residuals, you mean don't trim them. Is that right?
613059
CAPCOM
That's affirmative. No trim required.
613217
CAPCOM
Aquarius, check your MASTER ARM OFF, please.
613244
CDR
Okay, Houston. Burn's complete. Now we have to talk about powerdown, and what you want us to do with the PGNS.
613252
CAPCOM
Roger. We're looking at that right now, and you'll be the first one to get the word.
613319
CDR
And 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.
613348
CAPCOM
Roger, Jim. We'll get the word for you.
613524
CDR
And Houston, we're in an ATT HOLD mode. Can we turn off the thrusters?
613540
CAPCOM
Standby on that one, Jim.
613813
CAPCOM
Okay, 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.
613836
LMP
Okay. On 11, we've got DECA POWER, DECA GIMBAL OPEN. On 16, we've got the ATCA breaker OPEN.
613938
CDR
And 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.
613952
CAPCOM
Roger.
614124
CDR
And 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.
614145
CAPCOM
Roger. We gave you a GO on that earlier. Sorry, you must have missed it. Use the side hatch for urine dump.
614155
CDR
Okay.
614156
CAPCOM
And how are the stars out the window now?
614213
CDR
Well, 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.
614235
CAPCOM
Roger.
614243
CAPCOM
And 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?
614259
CDR
Okay, standby 1.
614310
CDR
Okay, I understand you want us to turn off the S-BAND TRANSMITTER/RECEIVER and bring it up in 5 minutes. Is that correct?
614316
CAPCOM
That's affirmative.
614320
CDR
Tell us when.
614342
CDR
And you want us to maintain attitude control?
614346
CAPCOM
Affirmative on the attitude control.
614348
CDR
That's AUTO attitude control. Okay. We'll maintain AUTO attitude control.
614356
LMP
Okay, 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?
614410
CAPCOM
Aquarius, leave the POWER AMPLIFIER the way it is. Turn the TRANSMITTER/RECEIVER OFF for 5 minutes.
614417
CAPCOM
Now.
614419
LMP
Okay, you tell me - you tell me when.
614422
CAPCOM
Okay, turn it off now. See you in 5 minutes.
614426
LMP
Okay, it's gone off. It's gone off for 5 minutes.
615105
LMP
- -
615244
CAPCOM
Aquarius, Houston. How do you read?
615252
LMP
Okay, you're loud and clear there, Jack.
615255
CAPCOM
Roger, same here. We're all - we're still discussing the next move.
615305
LMP
I figured it. Let's just make it a good one.
615318
CAPCOM
We'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?
615418
LMP
Okay. 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?
615521
CAPCOM
Okay. 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.
615538
LMP
Okay, it's ATT HOLD VERB 76 for the guy on watch. And the DAP load we've got right now is okay.
615818
CAPCOM
Aquarius, 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.
615837
LMP
Okay. The decision is to keep the platform, power down the computer, and we'll be standing by for further word on the powerdown, Jack.
615847
CAPCOM
Roger.
615934
CAPCOM
And Aquarius, for your information, we now have a 136 mile perigee.
615942
CAPCOM
Confirmed by doppler.
615947
LMP
Okay, 136 mile perigee now. That's very nice.
620009
LMP
Oh. 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.
620014
CAPCOM
I meant pericynthion.
620019
LMP
That's better!
554646
CAPCOM
Okay FLIGHT, you read his pitch and yaw and his high-gain meter.
554650
FLIGHT
That's affirmative.
554651
CAPCOM
And now you want roll right to 060?
554656
FLIGHT
Might 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.
554708
EECOM
FLIGHT, EECOM.
554709
FLIGHT
Go ahead, EECOM.
554710
EECOM
Okay, let's terminate the battery B charge at 55 +50.
554714
FLIGHT
Okay.
554715
EECOM
And at the same time, I'd sure like to have a cryo stir, all 4 tanks.
554720
FLIGHT
Let's wait until they get settled down a little more.
554722
EECOM
Roger.
554723
GNC
FLIGHT, GNC.
554724
FLIGHT
Go, GNC.
554725
GNC
I would still like to enable the other two quads for the maneuver.
554729
FLIGHT
Okay. When rolling to 060 you want them to enable C and D, right?
554735
GNC
Right.
554736
FLIGHT
Do you want them to disable A and B?
554738
GNC
No.
554738
FLIGHT
Okay. All four quads.
554740
GNC
They have coupled jet maneuvers -
554742
FLIGHT
Roger. Copy, CAPCOM?
554744
CAPCOM
Got it.
554746
INCO
FLIGHT, INCO.
554747
FLIGHT
Go, INCO.
554747
INCO
I'd like to confirm their configuration on their high-gain now.
554750
FLIGHT
Okay.
554751
INCO
I'd like to know what track mode they're in and what SERVO electronics they're in.
554756
FLIGHT
Okay, let's just standby 1 there. Now we'll C and D for roll to 060, terminate battery B charge.
554810
FLIGHT
Okay, 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?
554825
INCO
Yeah, the whole works.
554825
FLIGHT
Okay.
554831
FLIGHT
CAPCOM, we want the configuration of the CSM high-gain.
554934
INCO
That's good.
554935
FLIGHT
Okay.
555005
FLIGHT
Good report.
555009
GNC
FLIGHT, GNC.
555010
FLIGHT
Go, GNC.
555011
GNC
Can we verify that they reenabled C-4 thruster?
555020
FLIGHT
Okay. Verify that they re- - you're showing that disabled, yes?
555023
GNC
Yes.
555024
FLIGHT
CAPCOM, restore CM C-4 thruster; disabled.
555033
EECOM
FLIGHT, EECOM.
555034
FLIGHT
Go EECOM.
555034
EECOM
You've got 40 amp-hours back in battery B now.
555037
FLIGHT
Okay.
555042
EECOM
You got it, FLIGHT.
  • Possibly in response to seeing BAT B charge disabled.
555043
FLIGHT
Okay.
555054
FLIGHT
Okay, all flight controllers. I want to go around the horn and pick up anything you need configuration-wise. TELMU -
555101
TELMU
Go ahead, FLIGHT.
FLIGHT
- you still worried about any configuration items?
555106
TELMU
Negative. The LM heater current indicates that the LM was properly closed out. They apparently have not closed the LM hatch yet.
555114
FLIGHT
Okay. So you're happy that you don't need them to verify that - what was it, activation 2-3, those pages we were on?
555121
TELMU
That's right. That was TLC 2, and we're happy.
555124
FLIGHT
Okay.
555127
GUIDO
FLIGHT, GUIDANCE.
555129
FLIGHT
Go, GUIDANCE.
555130
GUIDO
Can we ask about the docking index again?
555133
FLIGHT
CAPCOM will get that for me.
555155
FLIGHT
Okay. Got your answer, GUIDANCE?
555157
GUIDO
Roger, FLIGHT.
555158
FLIGHT
Okay, go with it.
555231
FLIGHT
Okay. GNC, you got any configuration items here?
555235
GNC
Negative, FLIGHT.
555237
FLIGHT
CAPCOM, looks like the last item we need here is a stir on H₂ and O₂ at their convenience.
  • The fateful but inevitable request.
555244
CAPCOM
Okay.
555356
GUIDO
FLIGHT, GUIDANCE.
555359
FLIGHT
Go, GUIDANCE.
555400
GUIDO
We finally got a ∆H update. Do you want to just read it up to the crew or uplink it?
555408
FLIGHT
Let's see, now. Can we collapse deadbands and do all that good stuff if we uplink here?
555418
GUIDO
Uh. Yeah. That - why don't we just read it up to them?
555423
FLIGHT
If they enter it through the DSKY are they gonna do it?
555426
GUIDO
Standby 1.
555430
FLIGHT
Now, we haven't stabled out at that attitude yet, so I don't think we're gonna have any problems.
555434
GNC
FLIGHT, I don't think there's any problem, they haven't opened up deadbands yet.
555437
FLIGHT
Yeah, that's just what I'm saying. The time to do it is now, GUIDANCE.
555441
GUIDO
FLIGHT, GUIDANCE.
555442
FLIGHT
Go, GUIDANCE.
555443
GUIDO
As 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.
555457
FLIGHT
Okay. Why don't - you gotta pass the data for the crew checklist anyway on-board, don't you?
555504
GUIDO
Right.
FLIGHT
Don't you got a page update? Well, why don't we read it up to them and that'll serve both purposes.
555510
GUIDO
Alright.
555510
FLIGHT
Both have them enter it as well as why don't you tell them what page you want it in the checklist?
555514
GUIDO
Okay.
555518
TELMU
FLIGHT, TELMU.
555518
FLIGHT
Go, TELMU.
555519
TELMU
We show the LM overhead hatch is closed, and the heater current looks normal.
555523
FLIGHT
Okay.
555526
GUIDO
FLIGHT, GUIDANCE.
555527
FLIGHT
Go, GUIDANCE.
555527
GUIDO
We've had a hardware restart. I don't know what it was.
555529
FLIGHT
Okay. GNC, you want to look at it? See if you see any problems?
555537
FLIGHT
Roger. We're copying it, CAPCOM. We see a hardware restart.
555541
FLIGHT
You see an AC BUS UNDERVOLT there, GUIDANCE? Err - EECOM?
555546
EECOM
Negative, FLIGHT.
555548
FLIGHT
I believe the crew reported it.
555550
CAPCOM
We've got a MAIN B UNDERVOLT.
555551
EECOM
Okay, 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.
555554
FLIGHT
Roger.
555600
EECOM
We may have had an instrumentation problem, FLIGHT.
555603
FLIGHT
Roger.
555607
INCO
FLIGHT, INCO.
555608
FLIGHT
Go, INCO.
555609
INCO
We 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.
555633
FLIGHT
Okay.
555642
FLIGHT
INCO, you say you went to WIDE BEAM width there?
555644
INCO
Yes.
555649
FLIGHT
Let's see if we can correlate those times. Get the time when you went WIDE BEAM, INCO.
555655
INCO
Okay.
555702
CAPCOM
Do we have the floodlights off right now?
555704
TELMU
That's affirmative, FLIGHT.
555705
FLIGHT
Yeah, we can determine that from the LM current.
555737
FLIGHT
Roger, we copy that also.
555813
FLIGHT
EECOM, you see any AC problems? Looks like -
555815
EECOM
FLIGHT, EECOM.
FLIGHT
- we have a lot of instrumentation problems here. Go ahead.
555818
EECOM
That's affirm. He's flipping the 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.
555823
FLIGHT
Well, let's get some recommendation here, Sy, if you've got any better ideas.
555832
FLIGHT
Sy, what do you want to do? Hold your own, and -
555840
FLIGHT
- Sy, have you got a SIG SENSOR type problem there, or what?
555843
EECOM
FLIGHT, EECOM.
555844
FLIGHT
Go ahead.
555845
EECOM
He'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.
555902
FLIGHT
Okay.
555903
EECOM
We just gotta -
FLIGHT
FUEL CELL 1 -
EECOM
- back to MAIN A, FUEL CELL 3 back to MAIN B.
FLIGHT
- MAIN A, 3 to MAIN B.
555910
EECOM
Let's see what happens.
555911
FLIGHT
Okay, now is there - do we have instrumentation problems?
555916
EECOM
Well, 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 -
555929
FLIGHT
Okay.
EECOM
- the - yeah and he reported barber poles on the -
555935
FLIGHT
Roger.
EECOM
- on the fuel cell on-board, too, FLIGHT.
555936
FLIGHT
(unintelligible) yeah.
555938
GNC
FLIGHT, GNC.
555939
EECOM
Let's see if we can get our DC back.
555940
FLIGHT
Roger. Go ahead, GNC.
555941
GNC
Verify that the Quad Delta HELIUM VALVES are open.
555946
FLIGHT
You seeing an attitude problem or you seeing some BI-levels that are giving you problems?
555951
GNC
No, 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.
555959
FLIGHT
Quad number 2 HELIUM VALVE open?
560001
GNC
Quad Delta.
560002
FLIGHT
Quad Delta - HELIUM VALVE open, right?
560005
GNC
Right.
560010
FLIGHT
CAPCOM, do you want to verify the Quad Delta HELIUM VALVE is open, please.
560016
FLIGHT
Are there other problems in the RCS, Buck?
560020
CAPCOM
Okay, is that all we've come up with for them; have we got any other recommendations?
  • CAPCOM is anxious.
560025
FLIGHT
Yeah, we wanted to get FUEL CELL 1 configured to MAIN A, FUEL CELL 3 to MAIN B. Did you pass that up?
560032
EECOM
Let's attempt that, FLIGHT.
560037
FLIGHT
INCO, this seems to be an AC type problem, it may be tied into that high-gain thing you got.
560045
INCO
We went to WIDE BEAM with - FLIGHT - at 55:55:04, best we can tell.
560049
FLIGHT
Okay.
560106
EECOM
I copy, FLIGHT.
560109
EECOM
Let me commiserate on that.
560116
CAPCOM
Is 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.
560134
EECOM
FLIGHT, EECOM.
560135
FLIGHT
Go, EECOM.
560136
EECOM
Let's reverse the configuration request -
560138
FLIGHT
Okay, 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 -
560143
EECOM
FUEL CELL 2 is on MAIN A, FLIGHT -
560145
FLIGHT
Okay.
EECOM
- and I'm not going to ask to change that.
560147
FLIGHT
Okay, what do you want to do?
560148
EECOM
Let's try to put FUEL CELL 1 on MAIN B, FUEL CELL 3 on MAIN A. We'll use the other sensing circuitry.
560157
FLIGHT
FUEL CELL number 1 on MAIN B -
560200
EECOM
- FUEL CELL 3 on MAIN A.
560209
EECOM
We're not going to touch FUEL CELL 2, FLIGHT.
560212
FLIGHT
Okay, 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.
560228
FLIGHT
Can 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?
560235
EECOM
MAIN BUS A is reading 25 volts.
560238
FLIGHT
Okay. MAIN A -
560239
EECOM
And 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.
560248
FLIGHT
Okay.
560248
EECOM
So that's bona fide. AC BUS 2 is 0, which is reflected by the fact that we lost MAIN B.
560255
FLIGHT
AC BUS -
560259
EECOM
Standby, FLIGHT.
560303
FLIGHT
- zero output.
560307
EECOM
FLIGHT, EECOM.
560313
FLIGHT
Go ahead, EECOM.
560314
EECOM
Okay. If we want to keep - - standby, he's changed configuration, we've got BATTERY A on MAIN A.
560327
FLIGHT
Go ahead.
560327
EECOM
That's what I was going to ask you for, to put the battery on, FLIGHT.
560330
INCO
FLIGHT, INCO.
560331
FLIGHT
Go, INCO.
560331
INCO
We need OMNI Bravo. Our high-gain won't drive without AC 2.
  • The steerable antenna needed AC BUS 2 to power its servos.
560337
FLIGHT
Okay. You want OMNI Bravo?
560339
INCO
Right.
560348
FLIGHT
You don't think we're going to be able to get HIGH BIT RATE data here, do you? On the OMNIs.
560353
INCO
We may be. We've got the 210s.
560354
FLIGHT
You've got the 210s -
560356
INCO
Right.
FLIGHT
Okay, that'll save a bit of power. CAPCOM, recommend selection of OMNI Bravo, please -
560402
INCO
It's Charlie now.
FLIGHT
Okay, Charlie.
560403
INCO
He's maneuvering.
560405
CAPCOM
OMNI Charlie?
560406
FLIGHT
That's affirmative.
560406
INCO
Roger.
560427
INCO
Okay, FLIGHT, we've got OMNI Charlie and HIGH BIT RATE.
560431
FLIGHT
Okay. You have HIGH BIT RATE now off the 210s, right? OMNI -
560434
INCO
Right.
FLIGHT
Okay.
560458
EECOM
FLIGHT, EECOM.
560459
FLIGHT
Go, EECOM.
560500
EECOM
Okay. Let's get a readout on a couple of fuel cell pressures here -
560504
FLIGHT
Okay.
EECOM
- FUEL CELL 1 N₂ pressure. FUEL CELL 3 O₂ pressure. We're reading 0 N₂ pressure on FUEL CELL 1 and 13psi on FUEL CELL 3 O₂ 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.
560518
FLIGHT
Okay, you want FUEL CELL 1 -
560521
EECOM
N₂ pressure.
FLIGHT
- N₂ pressure. FUEL CELL 3, what do you want there?
560526
EECOM
O₂ pressure.
560527
FLIGHT
O₂ pressure. CAPCOM, let's get those as a start.
560533
GUIDO
FLIGHT, GUIDANCE.
560534
FLIGHT
Go, GUIDANCE.
560535
GUIDO
When his hardware restart he was doing a clearly fine maneuver, and that should have killed it, but we're still moving. We ought to stop it.
560545
FLIGHT
Are we using RCS now, Buck?
560558
FLIGHT
GNC, from FLIGHT.
560602
FLIGHT
GNC, from FLIGHT.
560604
GNC
GNC.
560605
FLIGHT
Did you see any problems in Quad D HELIUM VALVE? Does that look like that's cleared up?
560608
GNC
Roger, that's cleared up, FLIGHT, we're in good shape.
560610
FLIGHT
Okay. Now, are we using RCS now?
560612
GNC
That'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.
560617
FLIGHT
Okay. How much RCS are we using?
560622
GNC
Oh, we've used - our guess 25 pounds.
560627
FLIGHT
Okay. Give me minimum fuel usage configuration that'll keep me attitude.
560632
GNC
Roger.
560633
TELMU
FLIGHT, TELMU.
560634
FLIGHT
Go, TELMU.
560635
TELMU
The LM heater current's become essentially static.
560638
FLIGHT
Roger. Let's solve one problem at a time. Come back to me later on on it.
560705
CAPCOM
We confirming those numbers?
560720
FLIGHT
Buck, I need that RCS stuff as soon as you can get it.
560722
GNC
Roger, FLIGHT. He's turned off all jets now.
560724
FLIGHT
Okay.
560726
CAPCOM
Okay, we came up with those numbers, FLIGHT.
560729
FLIGHT
Okay, Sy. Give me your next best thing to try.
560746
FLIGHT
EECOM, from FLIGHT.
560747
EECOM
FLIGHT, EECOM.
560748
FLIGHT
Go ahead.
560751
EECOM
Why 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.
560806
FLIGHT
Okay, what do you want to do? Open-circuit FUEL CELL 1 and 3?
560809
EECOM
That's affirm, flight.
560810
FLIGHT
Okay. CAPCOM, let's recommend we open-circuit FUEL CELL number 1 and number 3 and leave FUEL CELL number 2 as-is.
560821
CAPCOM
Okay, 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.
560829
FLIGHT
Yeah - CAPCOM, let's amend that. EECOM, from FLIGHT.
560832
EECOM
FLIGHT, EECOM.
560833
FLIGHT
Why don't we just open-circuit 1 and make sure we don't have any problems getting that back onto the bus -
560838
EECOM
Okay, FLIGHT.
FLIGHT
- 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.
560841
EECOM
Roger.
560841
FLIGHT
Okay, CAPCOM. Let's just open-circuit one of those right now.
560857
GNC
FLIGHT, GNC.
560905
EECOM
That's roger, FLIGHT. That's the AC problem.
560908
FLIGHT
Roger.
560916
FLIGHT
Crew thinks they're venting something.
560918
EECOM
I heard it, FLIGHT.
560928
CAPCOM
Copy that, FLIGHT?
  • Pretty much as worked-up as the room gets.
560929
FLIGHT
Roger.
560933
FLIGHT
Okay, let's everybody think of the kinds of things that we'd be venting. GNC, you got anything that looks abnormal in your system?
560939
GNC
Negative, FLIGHT.
560943
FLIGHT
How about you, EECOM? You see anything that - with the instrumentation you've got that could be venting?
  • One can imagine EECOM here staring at his readouts and thinking "yes, FLIGHT, everything!"
560953
EECOM
That's affirm, FLIGHT.
561001
EECOM
Let me look at the system, FLIGHT, as far as the venting is concerned.
561003
FLIGHT
Okay. Let's start scanning. I assume you've called in your backup EECOMs?
561010
FLIGHT
EECOM?
561011
EECOM
FLIGHT, say again?
561012
FLIGHT
Have you called in your backup EECOMS now? See if we can get some more brain power on this thing?
561015
EECOM
We got one here.
561016
FLIGHT
Roger.
561017
INCO
FLIGHT, INCO.
561018
FLIGHT
Go, INCO.
561018
INCO
He's - he's - never mind, he's straightening up a little bit.
561021
FLIGHT
Okay.
561046
FLIGHT
Okay, 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 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 O₂ 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.
561147
GNC
FLIGHT, GNC.
561150
FLIGHT
Go, GNC.
561151
GNC
I have some jet configurations for you whenever you need them.
561154
FLIGHT
Okay.
561157
FLIGHT
Give them to me.
561201
GNC
Okay. Charlie 3, Charlie 4 to MAIN A. Bravo 3 and Bravo 4 to MAIN A. Charlie 1 and Charlie 2 to MAIN A -
561213
FLIGHT
Standby.
561221
GNC
Yeah; it's all of quad Charlie on MAIN A.
561224
FLIGHT
Okay.
561225
GNC
Plus Bravo 3 and Bravo 4.
561229
FLIGHT
Now, what are we going to be doing with these, GNC?
561232
GNC
That'll give us one jet in each direction on each axis.
561235
FLIGHT
Okay.
561236
GUIDO
FLIGHT, GUIDANCE.
561236
FLIGHT
Go, GUIDANCE.
561237
GUIDO
He's getting close to gimbal lock.
561239
FLIGHT
CAPCOM - 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.
561252
FLIGHT
GUIDANCE, from FLIGHT.
561253
GUIDO
Go ahead.
561253
FLIGHT
Could 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.
561302
GUIDO
Roger. I was going to recommend a P52 in a little bit anyway -
561305
FLIGHT
Well, it's going to take a while before we get to the point we're even thinking about a P52.
561309
GUIDO
Yeah.
561312
FLIGHT
Yeah, it'll coarse align itself there, won't it?
561318
GUIDO
It'll coarse align at -
561319
FLIGHT
Roger.
GUIDO
- any time itself.
561410
FLIGHT
Okay, EECOM. I'm coming back to you.
561413
EECOM
FLIGHT -
561414
FLIGHT
Go ahead.
EECOM
- I think the best thing we can do right now is start a power down.
561419
FLIGHT
Okay -
561420
EECOM
Let's go down the emergency 1-5.
561424
FLIGHT
You want to power down, let us look at the TM and all that good stuff, and then come back up.
561429
EECOM
That's affirm.
561430
INCO
FLIGHT, INCO. OMNI Bravo.
561432
FLIGHT
You want OMNI Bravo again?
561434
INCO
Right.
561434
FLIGHT
On board. OMNI Bravo.
561442
FLIGHT
CAPCOM, recommend OMNI Bravo.
561447
FLIGHT
Okay. What - you want to go to - power down - give me the page.
561451
EECOM
Emergency 1-5, FLIGHT, we'll go down - try to get a delta of 10 amps reduction.
561514
INCO
Okay, we've got OMNI Bravo, FLIGHT.
561522
FLIGHT
EECOM, do you want to go through that again? What do you want to power down to?
561525
EECOM
I want to power down a total of 10 amps, FLIGHT.
561528
FLIGHT
A total of 10 amps.
  • You can hear someone (FLIGHT, perhaps?) whistle in amazement at this.
561530
EECOM
That's affirm.
561531
FLIGHT
Okay.
561535
FLIGHT
CAPCOM, 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.
561544
GNC
FLIGHT, GNC.
561545
FLIGHT
Go, GNC.
561545
GNC
Can 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.
561551
FLIGHT
Why? You think you're going to have a thermal problem here?
561553
GNC
Well, we could have - if we stay there too long, or we -
561556
FLIGHT
Okay, we'll run into that one later, Buck -
561559
GNC
Okay.
FLIGHT
- I want to get our major problems sorted out now.
561602
CAPCOM
You want - you still want 1-5 down to 10 amps?
561604
FLIGHT
1-5 power down a delta of 10 amps, CAPCOM.
561632
FLIGHT
EECOM, from FLIGHT.
561634
EECOM
Go, FLIGHT.
561635
FLIGHT
You don't want to get fuel cell pumps off, do you?
561644
FLIGHT
Optics power is already off, I believe.
561647
EECOM
We can do that on FUEL CELL number 1, FLIGHT.
561650
FLIGHT
Okay, 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.
561720
EECOM
FLIGHT, EECOM.
561721
FLIGHT
Go, EECOM.
561722
EECOM
Would you not want to consider going to PTC?
  • Echoing GUIDO's suggestion earlier. Still not possible, as FLIGHT points out later.
561726
FLIGHT
Well, why don't we get this problem here resolved, right now -
561730
EECOM
This will aid our power down, I think -
561732
FLIGHT
Pardon?
EECOM
- this should aid our power down, I'd hope - wouldn't it?
561737
FLIGHT
Well, do you expect that we're going to be in a thermal problem for the next many hours? EECOM?
561744
EECOM
Well, don't know where to say the sun is right now, FLIGHT.
561747
GNC
Well, it's pretty close to quad A right now. Are we -
561751
EECOM
By 90 degrees?
561754
GNC
I 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.
561832
FLIGHT
GNC, from FLIGHT.
561837
FLIGHT
GNC, from FLIGHT.
561840
GNC
GNC.
561842
FLIGHT
Buck, 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.
561855
GNC
Well, 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.
561859
FLIGHT
Yeah, but you gotta get the CMC on, and keep it online. And you need a rather precise period of time for redamping there.
561910
GNC
In the order of about 20 minutes to damp out and spin up and then we don't need any of that.
561918
GNC
If we get a good spinup going then we're stable -
561919
FLIGHT
Okay, that might be a good idea. That would buy us some 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?
561938
GNC
He's a fair ways out right now, FLIGHT. He'd do another VERB 49 and fly back and then stabilize there.
562057
EECOM
FLIGHT, EECOM.
562058
FLIGHT
Go, EECOM.
562058
EECOM
Okay, 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 O₂ TANK 2 PRESSURE. I have no insight into that.
562112
FLIGHT
Okay.
562113
EECOM
Let's get - I guess we can put INVERTER 3 to MAIN A. AC 2.
562123
EECOM
Let's just do it temporarily -
562123
FLIGHT
Now, 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?
562132
EECOM
Nah, 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.
562140
FLIGHT
Well, the thing that concerns me is starting - is throwing equipment - we had a problem, we don't know the cause of the problem, and -
562146
EECOM
FLIGHT, 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.
562200
FLIGHT
Okay, 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.
562214
CAPCOM
He's asking how do we like his amperage setup right now?
562219
FLIGHT
Are you happy with his power level right now, EECOM?
562229
INCO
FLIGHT, INCO.
562230
FLIGHT
Go ahead.
562231
INCO
I'd like to firmly secure the high-gain before he starts getting into PTC.
562254
GNC
That's affirmative, FLIGHT.
562254
CAPCOM
GNC? What's firing now? You got something firing?
562259
GNC
Well, we've seen quite a bit of thruster activity.
562302
FLIGHT
Okay, I guess this kills the PTC, too, because we're not going to get into PTC as long as we've got something venting.
562312
GNC
Roger, FLIGHT. That agrees with what we're seeing here.
562315
EECOM
FLIGHT, EECOM.
562316
FLIGHT
Go, EECOM.
562317
EECOM
I'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.
562321
FLIGHT
INVERTER 1 on both AC.
562322
EECOM
That'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 cyros, 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.
562344
FLIGHT
Say that again. You think your fuel cell pumps -
562347
EECOM
Yeah. FUEL CELL 2 pumps I think are on AC 2.
562350
FLIGHT
Okay, but according to the checklist, he should have powered - he should have turned those off, right? Now, he said he was down through BMAG number 2 is in WARM UP, so he's already gone through the fuel cell pump stuff.
562401
EECOM
Okay. Good enough.
562404
FLIGHT
Okay, so you want to configure INVERTER 1 on both AC buses.
562408
EECOM
That's affirm, FLIGHT.
562421
CAPCOM
FLIGHT, 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?
562429
FLIGHT
No, we deleted that.
562431
CAPCOM
Alright.
562435
FLIGHT
You want to put INVERTER 1 on both AC BUSES. EECOM and CAPCOM, let's do it.
562440
CAPCOM
Okay.
562447
FLIGHT
EECOM, from FLIGHT.
562448
EECOM
FLIGHT, EECOM.
562449
FLIGHT
Monitor this bear when we switch again -
562450
EECOM
With you.
562500
FLIGHT
TELMU and CONTROL, from FLIGHT.
562503
TELMU
Go, FLIGHT.
562504
CONTROL
Go, FLIGHT.
562504
FLIGHT
Will you 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?
562509
CONTROL
Roger, FLIGHT.
562510
TELMU
We'll look.
562511
FLIGHT
Okay. And I want a report on that in about the next fifteen minutes. Quick look type stuff.
562515
CONTROL
Okay.
562517
FDO
FLIGHT, FDO.
562518
FLIGHT
Go, FDO.
562518
FDO
We're definitely seeing a vent in the data.
562520
FLIGHT
Okay.
562528
FLIGHT
Roger. We copy that, CAPCOM.
562537
EECOM
Fuel cell - FLIGHT, EECOM.
562538
FLIGHT
Go ahead.
562539
EECOM
FUEL CELL 2 PUMPS to AC 1.
562541
FLIGHT
You want FUEL CELL 2 PUMP to AC 1.
562544
EECOM
Affirmative.
562545
FLIGHT
CAPCOM, FUEL CELL 2 PUMP to AC 1.
562602
FLIGHT
EECOM, from FLIGHT.
562603
EECOM
FLIGHT, EECOM.
562603
FLIGHT
Have 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.
562609
FLIGHT
NETWORK, from FLIGHT.
562610
NETWORK
FLIGHT, NETWORK.
562611
FLIGHT
Bring me up another computer in the RTCC, will you?
562614
NETWORK
We got one machine on the RTCC and we got dual CPs downstairs.
562619
FLIGHT
Okay, I want another machine up in the RTCC and I want a bunch of guys capable of running delogs down there.
562624
NETWORK
Roger that.
562626
CAPCOM
FLIGHT, did you hear them say he's getting some rates? We want to know if he's firing any thrusters?
562632
FLIGHT
Roger. GNC, watch those thrusters, will you?
562635
GNC
GNC. Say again?
562636
FLIGHT
Have you got any thrusters firing?
562638
GNC
We're looking at that C-3 thruster, FLIGHT. It looks like it stays on most of the time.
562643
FLIGHT
Well, can we turn them all off and see if we've still got the rates or any build-up in rates?
562648
GNC
Well, 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.
562654
FLIGHT
Okay, but -
562655
CAPCOM
He's been trying to counteract the rates with DIRECT. He's been getting a negative pitch and a negative roll.
562703
FLIGHT
Okay.
562707
CAPCOM
But he asked if we were getting some thruster firings that were not being made by him.
562712
FLIGHT
I'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.
562730
FLIGHT
In other words, do - it would seem that 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.
562738
GNC
Roger, we'll give that a try, FLIGHT.
  • He sounds impressed.
562739
FLIGHT
Okay. And that might be of interest to the LM guys.
  • TELMU and CONTROL.
562742
CAPCOM
He also said it was coming past window number 1.
562745
FLIGHT
Roger, we got that.
562745
INCO
FLIGHT, INCO. Need OMNI Charlie.
562747
FLIGHT
OMNI Charlie, CAPCOM.
562751
FLIGHT
EECOM, from FLIGHT. What did - okay, we've got two good AC buses. What did all that tell you, now?
562759
EECOM
It tells me that - well, just give me about 2 more minutes, FLIGHT.
562804
FLIGHT
Okay. Take your time.
562848
FLIGHT
Roger. Concur, CAPCOM.
562854
TELMU
FLIGHT, TELMU. We copy.
562856
FLIGHT
Roger.
562857
FDO
FLIGHT, FDO.
562858
FLIGHT
Go, FDO.
562859
FDO
Two machines in the RTCC.
562900
FLIGHT
Okay.
563138
GNC
FLIGHT, GNC.
563139
FLIGHT
Go, GNC.
563140
GNC
We 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 -
563147
FLIGHT
Okay. Get me some real-time plotting on how we're using RCS here, will you?
563151
GNC
Roger, 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.
563158
FLIGHT
Okay, now what do you want again?
563200
GNC
Thruster Alpha 3 to MAIN A.
563206
FLIGHT
Alpha 3 to MAIN A.
563210
FLIGHT
CAPCOM, do you want to pass that up to the crew, please?
563218
FLIGHT
Give me a gross amount of RCS propellant consumed so far, GNC.
563225
GNC
Roger, FLIGHT. It'll take 30 seconds.
563226
FLIGHT
Okay.
563231
GNC
That's affirmative, FLIGHT. We're still below the limits.
563234
EECOM
Flight, EECOM.
563235
FLIGHT
Go, EECOM.
563237
EECOM
We'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 O₂ TANK 1. It's down to 318psi.
  • Nominal O₂ pressure is around 900psi. Normally, an automated pressure sensing switch would activate a heater as the tank depleted to heat the O₂ 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.
563252
FLIGHT
BATTERY -
EECOM
With MAIN B down, we have no heaters in O₂ 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.
563256
FLIGHT
Okay, what do you want to power down?
563258
EECOM
Well, where'd he say he got down to? BMAG 2 OFF? Not inclusive?
563303
FLIGHT
That's affirmative. BMAG 2 is in WARM UP.
563306
EECOM
I think we'll go ahead and turn that down - we still have the LM with us, right?
563310
FLIGHT
That's affirmative.
563311
EECOM
So - 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.
563323
FLIGHT
Okay. How much you want to power down? Another 10 amps?
563326
EECOM
Let's get the BMAG off and get the lights down to a minimum. Let's go down two more steps.
563330
FLIGHT
Okay. CAPCOM, we want to power down a little bit more. Want to get the BMAG off and the lights minimum there.
563357
FLIGHT
Okay, Sy. Now, how long do you want to leave this battery online?
563403
EECOM
I want to try and get it off as quick as I can -
563404
FLIGHT
Okay.
EECOM
- but I need to get the power down.
  • The spacecraft is currently drawing too much power for the one healthy fuel cell to supply, so the battery is currently required.
563407
EECOM
The 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.
563413
FLIGHT
I don't believe so.
563414
EECOM
FUEL CELL 1 and FUEL CELL 3 should be open-circuited.
563417
CAPCOM
We just had our last call for FUEL CELL 1 open-circuit, and we left FUEL CELL 3 as it was.
563423
EECOM
Let's take this open-circuit, FUEL CELL 3.
563424
FLIGHT
Open-circuit FUEL CELL 3.
563426
EECOM
Get it off the bus.
563429
GNC
FLIGHT, GNC.
563432
FLIGHT
Calling, FLIGHT. Say again?
563434
GNC
This is GNC, FLIGHT.
563435
FLIGHT
Go ahead.
563435
GNC
Yeah, 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.
563445
FLIGHT
Okay, what do you want to try now?
563447
GNC
We'd like to turn the Bravo jets all to be OFF, and all Delta to MAIN A.
563455
FLIGHT
Turn all Bravo OFF, and Delta to MAIN A, right?
563458
GNC
Roger. That will verify that it isn't a Bravo thruster that's causing the problem with attitudes.
563504
FLIGHT
Okay. CAPCOM, we'd like to turn all Bravo jets OFF and all Delta jets to MAIN A.
563514
CAPCOM
Roger.
563516
EECOM
FLIGHT, EECOM.
563517
FLIGHT
Go, EECOM.
563517
EECOM
Let's take BATTERY A off the MAIN.
563520
FLIGHT
We can support the -
563522
EECOM
That's affirm.
FLIGHT
- MAIN now on the one fuel cell even with the cryo O₂ going down?
563526
EECOM
That's affirm, FLIGHT.
563528
FLIGHT
Okay. What's your worry level on cryo O₂?
563532
EECOM
Say again, FLIGHT?
563534
FLIGHT
Okay. You want to -
563535
EECOM
I want to save the battery, FLIGHT.
563537
FLIGHT
Okay. Let's see, what battery have we got online, Sy?
563541
EECOM
Say again?
563541
FLIGHT
What battery have we got online?
563543
EECOM
BATTERY Alpha, FLIGHT.
563544
FLIGHT
BATTERY A, okay.
563545
EECOM
And 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 O₂ TANK 1.
563551
FLIGHT
Roger. Turn BATTERY A OFF, CAPCOM.
563615
EECOM
FLIGHT, EECOM.
563616
FLIGHT
Go, EECOM.
563617
EECOM
Let'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 O₂, and was located in the Command Module, so it stayed with the crew for the whole flight.
563623
FLIGHT
Say that again?
563625
EECOM
Let's isolate the surge tanks -
563626
FLIGHT
Why that?
EECOM
- in the Command Module.
563628
FLIGHT
I don't understand that, Sy.
563629
EECOM
I don't want to - I want to use the cryo as much as possible.
563632
FLIGHT
But that would seem to be the opposite, if you want to keep the fuel cell going.
563636
EECOM
The 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 and use it for re-entry.
  • You can find a detailed diagram of the O₂ system, including the Surge Tank, here.
563646
FLIGHT
Okay, I'm with you. I'm with you.
563649
EECOM
Roger.
563650
FLIGHT
CAPCOM, let's also isolate the surge tank.
563657
CAPCOM
Okay, you want to isolate the surge tank.
563700
FLIGHT
Yeah.
563701
CAPCOM
O₂ surge tank, right?
563701
FLIGHT
Yeah. What we're really doing is securing our entry systems right now.
563729
FLIGHT
Yeah, 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.
563759
FLIGHT
EECOM, from FLIGHT.
563810
FLIGHT
EECOM, from FLIGHT.
563811
EECOM
FLIGHT, EECOM.
563812
FLIGHT
Did you consider putting a battery on BUS B long enough to get the pressure up?
563816
EECOM
Well, 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. O₂ TANK 1 HEATERS are on MAIN A.
  • Good news, since MAIN B appears to be shot.
563828
FLIGHT
Well, we've got MAIN A with us, haven't we?
563846
EECOM
FLIGHT, EECOM.
563847
FLIGHT
Go, EECOM.
563847
EECOM
Okay. Since O₂ 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 O₂ 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.
563903
FLIGHT
O₂ -
563903
EECOM
And we'll watch the pressure.
FLIGHT
- TANK 1.
563914
EECOM
That's CRYOGENIC O₂ HEATER 1, FLIGHT.
563917
GNC
FLIGHT, we copy that. No problem.
563919
FLIGHT
No problem, CAPCOM.
563922
FLIGHT
CAPCOM, we want to get CRYO O₂ TANK number 1 HEATER ON.
563945
FLIGHT
You can stand the 5 amps on MAIN A?
563947
EECOM
That's affirm. We think so, FLIGHT.
564007
FLIGHT
Did you see your 5 amp increase in current there, EECOM?
564013
EECOM
That's affirm, FLIGHT.
564014
FLIGHT
Okay.
564014
EECOM
26.7 volts, looks good -
564017
FLIGHT
Okay.
EECOM
- we'll watch the pressure.
564018
EECOM
FLIGHT, to be consistent we ought to isolate the REPRESS package also.
  • The repressurization package, like the O₂ surge tank, was a reserve of pressurized oxygen gas in the Command Module.
564024
FLIGHT
Okay, you want to isolate REPRESS pack.
564040
FLIGHT
AFD, from FLIGHT.
564043
AFD
Go ahead, FLIGHT.
564043
FLIGHT
Get 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?
564055
AFD
Okay, FLIGHT.
564056
FLIGHT
Okay?
564057
AFD
And we've got the voice recorder and we're starting to transcribe that.
564101
FLIGHT
Okay, 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?
564112
FLIGHT
Okay.
564122
FLIGHT
TELMU and CONTROL, from FLIGHT.
564125
CONTROL
Go, FLIGHT.
564126
FLIGHT
Roger. I want LM manning around the clock.
564129
CONTROL
Roger.
564130
EECOM
FLIGHT, EECOM.
564131
FLIGHT
Go ahead, EECOM.
564132
EECOM
I want the fans on in O₂ tank 1, we're not seeing a pressure increase. We can stand it.
564138
FLIGHT
You can stand it?
564140
EECOM
That's affirm.
564141
FLIGHT
Fans on in TANK 1, right?
564144
EECOM
Affirmative, FLIGHT.
564146
FLIGHT
CAPCOM, do you want to bring the fans on in TANK 1?
564148
EECOM
It's just 1 amp, FLIGHT.
564150
FLIGHT
Okay.
564152
EECOM
Okay, he's got an MC&W for - varied reasons.
564220
GNC
FLIGHT, GNC.
564222
FLIGHT
Go ahead, GNC.
564223
GNC
It looks like the vehicle has stabilized considerably over the last few minutes.
564228
FLIGHT
Okay. 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?
564241
GNC
It's possible, FLIGHT. We really don't know yet, though.
564245
FLIGHT
Okay. 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.
564255
GNC
Right now he has a -0.10 of a degree in pitch. And yaw and roll are very close to 0.
564301
FLIGHT
Okay.
564302
EECOM
FLIGHT, EECOM.
564303
FLIGHT
Go ahead, EECOM.
564304
EECOM
The pressure in O₂ 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 O₂ for the third fuel cell - for FUEL CELL 2, rather.
  • PSI. At 56:32:37 it was reported at 312psi.
564319
FLIGHT
The 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.
564327
EECOM
We 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.
564328
FLIGHT
You saw the current - okay, look -
564332
EECOM
Let's check it anyway, FLIGHT, you're right.
  • But that could be a coincidence or something else could be wrong, so he comes around.
564333
FLIGHT
It 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.
564339
EECOM
Okay, panel 226. CRYOGENIC O₂ HEATER 1, MAIN A circuit breaker.
564349
FLIGHT
I'm sorry, I didn't catch you there. CRYO O₂ TANK 1? Panel 226?
564353
EECOM
CYRO O₂ HEATER 1, MAIN A, panel 226.
564357
FLIGHT
Roger.
564358
EECOM
Also, FLIGHT, let's check the FAN MOTOR circuit breakers TANK 1, on panel 226 also.
564408
FLIGHT
FAN MOTOR.
564410
EECOM
CRYO 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.
564418
FLIGHT
Get that, CAPCOM?
564420
CAPCOM
I've got the 226 CRYO O₂ HEATER 1 MAIN A, and CRYO FAN MOTORS TANK 1, three of them on -
564427
FLIGHT
That's right. All three phases.
564431
FLIGHT
EECOM, 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.
564450
FLIGHT
TELMU, from FLIGHT.
564452
TELMU
Go ahead, FLIGHT.
564452
FLIGHT
I 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.
564457
TELMU
Roger.
564458
FLIGHT
Okay.
564517
CAPCOM
We got the circuit breakers. All in, FLIGHT.
  • The circuit breakers popped out when broken and pushed in when the circuit was closed.
564522
FLIGHT
Roger. Copy, all circuit breakers in.
564615
EECOM
FLIGHT, EECOM.
564615
FLIGHT
Go ahead, EECOM.
564616
EECOM
Don't we have both BMAGs OFF?
564626
FLIGHT
CAPCOM, would you verify that both BMAGs are OFF, please?
564640
FLIGHT
You want to bring it off, right EECOM?
564643
EECOM
Affirmative, FLIGHT.
564644
FLIGHT
CAPCOM, let's get it off.
564732
FLIGHT
CAPCOM, from FLIGHT.
564734
CAPCOM
Go, FLIGHT.
564735
FLIGHT
Will 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.
564748
CAPCOM
Okay. You want a survey of panels 1 and 2 on gauges?
564753
FLIGHT
Yeah.
564754
CAPCOM
Okay. And talkbacks, huh?
564757
FLIGHT
That's affirmative. Figure out some code that you can use and - I think that's something we should have gotten started a while ago.
564810
FDO
FLIGHT, FDO.
564821
FLIGHT
See that juice is still going down there, EECOM. You got any more suggestions?
564828
EECOM
FLIGHT, EECOM.
564829
FLIGHT
Any more suggestions in trying to pump up O₂ TANK 1 pressure?
564832
EECOM
No. FLIGHT, we're gonna hit 100psi in 1 hour and 54 minutes. That's the end, right there.
564847
FLIGHT
Okay, 100psi -
564849
EECOM
Less than 2 hours, now.
565056
FLIGHT
FDO, from FLIGHT.
565057
FDO
Go ahead, FLIGHT.
565058
FLIGHT
Whatever 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.
565113
FDO
Okay, FLIGHT.
565114
FLIGHT
So 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.
565127
FDO
Okay, and I'm assuming that you want fast-as-possible return.
565132
FLIGHT
Yeah, I think that's the case.
565134
FDO
Okay. We'll work on it from that sideline, FLIGHT -
565136
FLIGHT
Okay.
FDO
Should be no problem.
565138
GUIDO
I copy that, FLIGHT.
565146
EECOM
FLIGHT, EECOM.
565148
FLIGHT
Go ahead, EECOM.
565149
EECOM
Okay, listen. There is a possibility that we blew a O₂ 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 O₂ pressure is gone. Now, FUEL CELL 1's O₂ 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.
565224
FLIGHT
That sounds like a good assumption, right there.
565226
EECOM
Yeah. FUEL CELL 3 is lost anyways, FLIGHT.
565229
GNC
FLIGHT, GNC.
565230
FLIGHT
Go ahead, GNC.
565231
GNC
Turn Charlie 1 thruster OFF.
565234
FLIGHT
You want to turn Charlie 1 OFF? Why?
565236
GNC
Well, looks like we're getting a lot of firing out for no reason.
565241
FLIGHT
Okay, CAPCOM, recommend THRUSTER C-1 to OFF.
565256
CAPCOM
Say again, FLIGHT?
565257
FLIGHT
THRUSTER C-1 to OFF.
565300
CAPCOM
C-1 and -2 OFF.
565301
FLIGHT
No. C-1. OFF. I added a word in there. Turn THRUSTER C-1 OFF.
565325
FLIGHT
EECOM, from FLIGHT.
565326
EECOM
FLIGHT, EECOM.
565327
FLIGHT
Why don't you show me where you think that problem is?
565329
EECOM
Okay. Clint's coming up.
565516
EECOM
FLIGHT, EECOM.
565523
FLIGHT
Go 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.
565524
EECOM
We need to get the - make sure the inline heaters for FUEL CELLS 1 and 3 are OFF.
565550
FLIGHT
EECOM, from FLIGHT.
565551
EECOM
FLIGHT.
565552
FLIGHT
You want to shut off both reactant valves to FUEL CELL number 3?
565554
EECOM
It's dead anyway, FLIGHT.
565556
FLIGHT
Okay.
565556
EECOM
And the inline heaters OFF in FUEL CELLS 1 and 3, please.
565600
FLIGHT
What 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 O₂ right now. And we may be losing our O₂ through FUEL CELL number 3, the O₂ manifold - inasmuch as they're manifolded together commonly. Looks like the O₂ 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.
565643
FLIGHT
CAPCOM, let's close the REACTANT VALVE to FUEL CELL number 3.
565649
CAPCOM
Okay, close REACTANT VALVE to FUEL CELL number 3.
565653
CAPCOM
And you're saying that 1 and 2 look okay?
565657
FLIGHT
Well, 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 O₂ flow.
565704
CAPCOM
Okay.
565713
GNC
FLIGHT, GNC.
565714
FLIGHT
GO, GNC.
565715
GNC
Some more jet reconfigurations to see if we can hold the attitude.
565718
FLIGHT
Okay.
565719
GNC
We'd like to turn Charlie 2 OFF -
565720
FLIGHT
Wait, 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?
565728
GNC
I'd think we'd like to get into a controlled drift rather than just some random thing, FLIGHT.
565734
FLIGHT
Standby.
565755
FLIGHT
Do you want them to go through that whole smash for fuel cell shutdown, Sy? I assume you do - heaters and all?
565801
FLIGHT
EECOM?
565803
EECOM
That's affirm, FLIGHT. He's gone through much of it already, got the pumps off.
565806
FLIGHT
Okay. You want them to go through the whole fuel cell shutdown. Heaters and all.
565810
EECOM
Heaters, reactant valves, and the pumps of course he's already done.
565813
FLIGHT
Okay. Have them go ahead, CAPCOM.
565815
EECOM
And get the inline heaters OFF on FUEL CELL 1 also, FLIGHT.
565819
FLIGHT
Inline heaters OFF on FUEL CELL 1.
565821
EECOM
Roger, it'll cut the current requirement down, anyway.
565855
CAPCOM
The COMM holding up? Sounds like he's going out.
565858
FLIGHT
How you doing there, INCO? From a standpoint of OMNI-switching?
565902
INCO
We might be a little better on Bravo.
565904
FLIGHT
Okay. 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.
565911
INCO
Okay. We can turn the tape recorder OFF.
565914
FLIGHT
EECOM, from FLIGHT.
565915
EECOM
FLIGHT, EECOM.
565916
FLIGHT
You don't need the tape recorder, do you?
565917
EECOM
Heck, no. Get it off.
565918
FLIGHT
Let's get it off.
565921
INCO
It may be already off, but that's one thing we don't need.
565924
EECOM
Let'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.
565930
INCO
Is that the only thing we can give up? We turn the POWER AMPL OFF, we won't get HIGH BIT RATE.
565935
FLIGHT
CAPCOM, from FLIGHT.
565936
CAPCOM
Go.
565937
FLIGHT
Let's also verify tape recorders OFF, please.
565940
CAPCOM
Okay, I think we -
565942
FLIGHT
I 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.
565949
CAPCOM
Yeah.
565950
EECOM
Yeah, that's affirm, FLIGHT. Tape record - we'll skip a step and go tape recorder OFF.
570012
RECOVERY
AFD, meet RECOVERY. RECOVERY loop.
570018
FLIGHT
What was that, CAPCOM?
570022
GUIDO
We copy, FLIGHT.
570023
FLIGHT
What was that, GUIDANCE?
570025
GUIDO
He had an 06 18 he couldn't get rid of; he's got rid of it now.
570104
FDO
FLIGHT, FDO.
570118
CAPCOM
Okay, 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.
570127
FLIGHT
Did you get some kind of master? We got it on tape, I'm sure we can get it off the tape.
570132
CAPCOM
Alright. That's affirm. I'd say I have 95% of the ones he read.
570135
FLIGHT
Okay.
570218
FDO
FLIGHT, FDO.
570219
FLIGHT
Go, FDO.
570220
FDO
When the systems men can stand it, I need two minutes for a checkpoint to save all this data.
570226
FLIGHT
I don't see why we couldn't - EECOM, GNC, can you stand a checkpoint right now?
570236
EECOM
It only takes a minute, I guess I'll have to if we need it, FLIGHT.
570238
GNC
Go ahead, FLIGHT.
570239
FLIGHT
Yeah, I think it'd be good to get a checkpoint. Go ahead.
570241
FLIGHT
EECOM, have you deduced anything - have you seen your REACTANT VALVES go off? You seen flow cease?
570251
EECOM
Can't tell, FLIGHT.
570252
FLIGHT
Yeah.
570252
EECOM
They were open-circuited, and the pressure - still appears to be going down.
570259
FLIGHT
Yup.
570327
FDO
Negative, FLIGHT.
570337
EECOM
FLIGHT, EECOM.
570338
FLIGHT
Go, EECOM.
570339
EECOM
We'd better confirm that the FUEL CELL 3 REACTANT VALVE circuit breaker on panel 226 was closed when he shut those.
570347
FLIGHT
FUEL CELL 3 REACTANT circuit breaker on what panel?
570351
EECOM
226.
570354
EECOM
They'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.
570358
FLIGHT
Okay, good idea.
570400
CAPCOM
You want them - close the circuit breaker -
570402
FLIGHT
Yeah.
CAPCOM
- on the valve, and then -
570403
FLIGHT
Yeah.
570405
EECOM
Yeah, FLIGHT; he should have gotten a barber pole on that.
570417
FLIGHT
Yeah, wouldn't he get a barber pole when he turned the reactants off? EECOM?
570422
EECOM
Affirm, FLIGHT.
570424
FLIGHT
Even with the circuit breaker open?
570426
EECOM
No -
570426
FLIGHT
No. 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."
570435
FDO
Okay, FLIGHT. We have our checkpoint.
570437
FLIGHT
Okay. 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.
570449
GNC
Go on thruster A-4, FLIGHT.
570451
FLIGHT
Okay. Go on thruster A-4, CAPCOM.
570452
INCO
OMNI Charlie, FLIGHT.
570453
FLIGHT
Roger. And OMNI Charlie.
570613
FLIGHT
Okay. 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.
570653
FLIGHT
And the delog is in way now. Roger.
570714
FLIGHT
Okay, 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.
570720
EECOM
FLIGHT, EECOM.
570721
FLIGHT
Go.
570722
EECOM
The 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.
570737
FLIGHT
Okay, now the next question is: are you willing to do that on FUEL CELL number 1?
570742
EECOM
That's the question we're pondering, FLIGHT. We've got to come up with an answer on that one.
570747
FLIGHT
Soon. FUEL CELL 2 is working okay.
570749
EECOM
That's affirmative.
570751
FLIGHT
Unless 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.
570756
EECOM
That's affirmative.
570757
FLIGHT
Okay - okay. GNC, FLIGHT.
570801
GNC
GNC.
570802
FLIGHT
You stabilized now? - standby.
570806
FLIGHT
Here comes configuration, I think it's yours.
570834
FLIGHT
I didn't copy all those; did you, GNC?
570836
GNC
Roger, FLIGHT. We concur.
570838
FLIGHT
Is that good? How are the rates?
570841
CAPCOM
You copy those, GNC?
570842
GNC
It's holding down around a tenth of a degree per second, FLIGHT. Isolating, he's in ACCEL CMD, so -
570850
FLIGHT
ACCEL CMD?
570851
GNC
Right.
570853
FLIGHT
Alright.
570857
CAPCOM
FLIGHT, did you copy all those thrusters?
570859
FLIGHT
Go ahead. Who's calling?
570902
CAPCOM
CAPCOM. Did you copy all those -
570903
FLIGHT
I didn't copy them all, Jack. GNC, did you copy them all?
570906
GNC
That's affirmative, FLIGHT.
570907
FLIGHT
Do you like that configuration for right now?
570909
GNC
Yes.
570910
FLIGHT
As best you can tell - best you can tell, the rates are okay. And he's flying ACCEL CMD.
570919
GNC
Roger, FLIGHT.
570920
FLIGHT
No rate damping, then, right?
570922
GNC
Roger.
570924
FLIGHT
Are both BMAG packages off?
570927
GNC
Yes, they are.
570929
FLIGHT
Okay.
570945
FLIGHT
Standby. EECOM, you need anything?
570951
EECOM
Roger, FLIGHT. We'll take those.
570953
CAPCOM
We want those?
570955
EECOM
Roger.
570957
FLIGHT
What do you want?
570959
EECOM
Get him to go through the meters -
571000
FLIGHT
Okay.
EECOM
- on FUEL CELL 1 and 3.
571002
FLIGHT
Okay. Just FUEL CELL 1 and 3, Jack.
571125
FLIGHT
EECOM, I don't like the way that O₂ pressure's going down. If you want to do something about these other reactant valves, let's make up our mind.
571131
EECOM
Okay.
571132
FLIGHT
Don't you think?
571132
EECOM
Let me get that for you in a minute, FLIGHT. Let's standby on these readouts.
571136
FLIGHT
Yeah, okay. Anybody can copy the readouts. Be sure you're discussing these reactants.
571154
CAPCOM
Hey, 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?
571203
FLIGHT
EECOM? - he's busy.
571206
EECOM
Go, FLIGHT.
571207
FLIGHT
Do you want to close out the REPRESS pack? I think that came on for them before.
571212
EECOM
We indicated earlier that we'd like to get it closed off -
571214
FLIGHT
Yes, Jack.
571223
EECOM
FLIGHT, EECOM.
571224
FLIGHT
Go ahead.
571225
EECOM
Okay, 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.
571243
FLIGHT
Yeah. What is this pounds on your display, Clint?
571247
EECOM
On O₂?
571248
FLIGHT
Yup.
571249
EECOM
That's - that's invalid.
571251
FLIGHT
Okay.
571257
EECOM
And 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.
571304
FLIGHT
Which circuit breaker is that? The one on 226?
571306
EECOM
Roger.
571310
FLIGHT
That's FUEL CELL number 1.
571312
EECOM
That's right, FUEL CELL reactants number 1.
571314
FLIGHT
Alright.
571316
FLIGHT
Is he done with that readout yet?
571320
EECOM
I didn't copy the last part of it there, FLIGHT -
571332
FLIGHT
EECOM, FLIGHT.
571334
EECOM
Go, FLIGHT.
571334
FLIGHT
Is 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?
571345
EECOM
On the O₂ tank?
571346
FLIGHT
Yes.
571352
FLIGHT
You understand my question?
571352
EECOM
I 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.
571400
FLIGHT
Alright.
571415
FLIGHT
Yeah, we copy that. Tell them we're debating shutting off the reactants on 1.
571419
EECOM
FLIGHT, EECOM.
571419
FLIGHT
Go ahead.
571420
EECOM
The temperature is the only thing we have.
571422
FLIGHT
And does it correlate?
571423
EECOM
Pretty closely.
571424
FLIGHT
You're saying that I'm looking at a valid pressure in that tank, and it's still going down.
571428
EECOM
That's the way it looks, FLIGHT.
571429
FLIGHT
Therefore?
571430
EECOM
Therefore we need to go to FUEL CELL 1 and turn off the reactants.
571434
FLIGHT
CAPCOM, FUEL CELL 1 reactants. Circuit breaker and a switch.
571438
CAPCOM
Okay - you want them to go through the fuel cell shutdown procedure on 1?
571442
FLIGHT
EECOM?
571443
EECOM
Say again, FLIGHT?
571443
FLIGHT
Do you want them to go through the fuel cell shutdown procedure on 1?
571447
EECOM
That's affirmative.
571448
FLIGHT
Yes, Jack.
571450
CAPCOM
Because -
571451
FLIGHT
Because the tank 1 is still going down. Pressure and temp - pressure going down, temperature confirms it.
571457
CAPCOM
Okay.
571505
FLIGHT
EECOM, FLIGHT.
571506
EECOM
Go ahead, FLIGHT.
571507
FLIGHT
Of course, you want to ask yourself if you want to open 3.
  • Open-circuit FUEL CELL 3, perhaps?
571513
EECOM
Open 3?
571514
FLIGHT
Yeah. You don't want to do that?
571516
EECOM
Negative, let's leave 3 like it is.
571526
GNC
FLIGHT, GNC.
571528
FLIGHT
Standby.
571531
FLIGHT
What MAIN BUS do you want up?
571533
EECOM
MAIN A.
571534
FLIGHT
Just like we -
571534
EECOM
Just like it is.
571535
FLIGHT
Just like it is. FUEL CELL 2's on MAIN A.
571539
EECOM
That's affirm.
571541
INCO
FLIGHT, INCO.
571541
FLIGHT
Go.
571542
INCO
OMNI Bravo.
571545
FLIGHT
OMNI Bravo, too, Jack.
571601
FLIGHT
EECOM, FLIGHT.
571603
EECOM
Go ahead, FLIGHT.
571604
FLIGHT
How long can I leave that stuff off and still turn it back on? Any time at all?
571608
EECOM
Negative, 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.
571611
FLIGHT
Alright.
571620
FLIGHT
EECOM, FLIGHT.
571623
FLIGHT
I don't know. That's what I'm asking, but we've got that shut off now.
571631
FLIGHT
Okay. When you can.
571707
EECOM
That's right, FLIGHT.
571708
FLIGHT
You're ready for that now. Sure, absolutely, huh EECOM?
571711
EECOM
That's it, FLIGHT.
571712
FLIGHT
It's still going down and it's not possible that thing is sort of bottoming out, is it?
571717
EECOM
Well, the rate is slower but we have a little less pressure too, so we would expect it to be a little bit slower.
571723
FLIGHT
You are sure, then; you want to close it.
571726
EECOM
Seems to me we have no choice, FLIGHT.
571731
FLIGHT
Well.
571733
EECOM
Standby one minute; I'll poll my back room.
571735
FLIGHT
It went down again. One more.
571750
EECOM
We're go on that, FLIGHT.
571752
FLIGHT
Okay. That's your best judgement; we think we ought to close that off, huh?
571755
EECOM
That's affirmative.
571756
FLIGHT
It's dropping down to 234. Yeah. Okay. FUEL CELL number 1 REACTANTS coming OFF.
  • psi.
571820
GNC
FLIGHT, GNC.
571821
FLIGHT
Go ahead.
571822
GNC
I 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.
571831
FLIGHT
Is he under DAP control?
571832
GNC
Well, he goes to it occasionally -
571834
FLIGHT
Okay.
GNC
- he's in - RATE CMD right - ACCEL CMD right now, but -
571836
FLIGHT
Okay. Okay. He's got A/C off, huh?
571840
GNC
Right.
571841
FLIGHT
CAPCOM, when you get a spare minute there, Jack needs to enable B/D ROLL in the DAP if he wants to use it.
571847
FLIGHT
If he wants to use the DAP, that is.
571855
FLIGHT
Jeez, it's really going down.
571918
EECOM
FLIGHT, EECOM.
571918
FLIGHT
Go.
571919
EECOM
Okay, is the - LM gotten all set up for using LM systems for supporting the CSM?
571926
TELMU
That's affirmative.
571927
FLIGHT
Yes.
571928
EECOM
Okay. We'll get you time as to what it looks like we'll have for power here, shortly.
571933
FLIGHT
TELMU and CONTROL, FLIGHT.
571935
CONTROL
CONTROL here.
571937
FLIGHT
Keep reminding me of that heater; now I don't want to let that thing go too long.
571940
CONTROL
Okay. 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.
571949
FLIGHT
Yeah, okay, Hal. Go get 'em.
571951
TELMU
Okay; and FLIGHT, TELMU. We're working on a procedure right now that powers the LM internally from its own power.
571957
FLIGHT
Yes. Fine.
571958
INCO
FLIGHT, INCO.
571959
FLIGHT
Go.
571959
INCO
Save you a little more power to turn the HIGH GAIN antenna switch to OFF.
572003
FLIGHT
HIGH GAIN antenna OFF?
572005
INCO
POWER switch OFF.
572006
FLIGHT
POWER switch. You're doing okay on the OMNIs, huh?
572009
INCO
Yes. We've got the 210s.
572011
FLIGHT
Okay. CAPCOM, he can turn the HIGH GAIN antenna POWER switch OFF; we're doing fine on the OMNIs. We've got the big dish.
572017
EECOM
FLIGHT, EECOM.
572017
FLIGHT
Go.
572018
EECOM
Let's charge BATTERY A.
572019
FLIGHT
Yeah, I was wondering about that. Do you - let me get the HIGH GAIN POWER off first, okay? Clint?
572025
EECOM
Okay.
572033
FLIGHT
How much - how many amps will that give us, EECOM?
572035
EECOM
About 1.3, 1.4 amps - - amp-hours per hour. The cost is about 4.5 amps.
  • The rate of battery charge.
572043
FLIGHT
So it's no big deal on the amps.
572044
EECOM
That's right. And we'd like to use whatever time we have to put energy back into the battery.
572050
FLIGHT
Yeah, and I see O₂ tank 1 pressure is 217.
572053
EECOM
That's affirmative. It's still coming down.
572055
FLIGHT
CAPCOM, FLIGHT.
572057
CAPCOM
Go, FLIGHT - standby.
572108
FLIGHT
GUIDANCE, you want anything done with the CMC right now?
572111
GUIDO
FLIGHT, we would like a VERB 74 before they power it down.
572115
FLIGHT
VERB 74, CAPCOM.
572116
CAPCOM
You ready for it now?
572118
GUIDO
Standby, FLIGHT, let me the flight - site configured.
572130
FLIGHT
EECOM, FLIGHT.
572132
EECOM
Go ahead, FLIGHT.
572133
FLIGHT
Does the temperature in tank 2 correspond with the pressure reading?
572136
EECOM
Let me see how close it is, FLIGHT.
572150
GUIDO
FLIGHT, GUIDANCE -
572150
FLIGHT
Go.
GUIDO
- we're ready.
572152
FLIGHT
Yeah; VERB 74 you want?
572154
GUIDO
Roger.
572155
FLIGHT
VERB 74.
572200
EECOM
FLIGHT, EECOM.
572200
FLIGHT
Go.
572201
EECOM
Temperature and pressure correspond - they verify that the pressure reading's right.
572206
FLIGHT
In tank 2?
572208
EECOM
In tank - standby.
572213
EECOM
That's right, FLIGHT. Tank 2.
572214
FLIGHT
Okay. 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?
  • MAIN DC BUS B
572222
EECOM
It's not likely, FLIGHT.
572224
FLIGHT
What's not likely, Clint?
572225
EECOM
Not likely to be able to - actually have anything left in the tank.
572231
FLIGHT
You don't think so?
572232
EECOM
I don't think so, but let's - we'll pulse (??) that one to you.
572235
FLIGHT
Alright.
572235
EECOM
Let me get you a time it looks like we've got on tank 1 here.
572238
FLIGHT
Alright.
572257
FLIGHT
TELMU, FLIGHT.
572258
TELMU
Go, FLIGHT.
572259
FLIGHT
Is there anything simple that we can refer the crew to to get them thinking about using the LM here? Have you got anything - checklist, paperwork that'll describe to them what your intentions are?
572312
TELMU
Negative, 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.
572319
FLIGHT
I'm sure you do. What do they amount to? Flying with the tunnel open?
572323
TELMU
Roger. Just a LM, low power - low - supplying power to the CSM.
572328
FLIGHT
Supplying power to the CSM?
572330
TELMU
Yes; about 5 amps.
572333
FLIGHT
To what?
572335
TELMU
To their MAIN BUS B.
  • Which hasn't actually functioned since the accident.
572337
FLIGHT
Okay. 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?
572347
TELMU
Just anything they might need it for.
572349
FLIGHT
GNC and EECOM?
572350
GNC
Go, FLIGHT.
572351
FLIGHT
What power do you need from the LM?
572356
EECOM
Okay, we'll -
572401
FLIGHT
That's right.
572402
EECOM
We confirm that here.
572407
EECOM
FLIGHT, EECOM. Looks like we've got about 40 minutes left in that tank.
572412
EECOM
That's affirmative.
572413
FLIGHT
Yes.
572416
EECOM
Like to get battery A on charge, FLIGHT.
572421
FLIGHT
Now -
572445
FLIGHT
CAPCOM, 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.
572524
GUIDO
FLIGHT, GUIDANCE.
572524
FLIGHT
Go ahead.
572525
GUIDO
We didn't get a good recording on that VERB 74, we'll need them to do it again.
572531
EECOM
FLIGHT, EECOM.
572531
FLIGHT
Go ahead.
572532
EECOM
We'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 -
572540
FLIGHT
Clint, 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.
572553
FLIGHT
I'm trying to be sure that you're satisfied that there's nothing else we can do.
572557
EECOM
About all we can do is power down and let heat leak help us some - which is probably going to be trivial.
572603
FLIGHT
Okay. There's nothing else you want to try.
572607
FLIGHT
That'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.
572613
EECOM
Sure don't, FLIGHT.
572615
FLIGHT
Okay, what are other power do you want to take off before we start the charge?
572618
EECOM
Well, looks like we're going to get into the control area. Whatever they can give up we'll have to come up with, here.
572623
FLIGHT
Okay, are you ready to go ahead and charge BATTERY A?
572626
EECOM
That's affirmative.
572626
FLIGHT
CAPCOM, why don't they get all they can in BATTERY A?
572629
CAPCOM
Okay, and Jack also asked me if we wanted to get a P52 and get the LM platform up with the -
572635
FLIGHT
What do you think of that? GUIDANCE?
572638
GUIDO
Go ahead, FLIGHT.
572639
FLIGHT
CONTROL. 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.
572647
CONTROL
That's too much power in my mind, FLIGHT, to keep that thing running for all that time.
572651
FLIGHT
Okay, therefore you don't -
572653
CONTROL
My vote is not to do that.
572654
FLIGHT
Yeah.
572655
GUIDO
Mine, too.
572656
FLIGHT
Okay, CAPCOM, we don't see any need in doing that, because we wouldn't be using the LM platform until about 79 hours.
572703
CAPCOM
Okay, you don't want to worry about the LM platform. We'll align it later with the AOT, huh?
572711
CONTROL
FLIGHT, CONTROL.
572716
FLIGHT
Yeah.
572741
FLIGHT
Did you say BATTERY A charge?
572742
CAPCOM
Yup.
572743
FLIGHT
Okay. EECOM, we charging A? Watch it, there, okay?
572746
EECOM
I'm watching; it's fine.
572748
FLIGHT
Okay.
572751
FLIGHT
EECOM?
572752
EECOM
Go, FLIGHT.
572753
FLIGHT
Go 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 -
572804
EECOM
Just power down, FLIGHT. All we can power down will put us in that much better configuration.
572808
FLIGHT
Okay, I got that part but are there any other things that you can do besides that, is what I'm getting at?
572813
EECOM
Negative, FLIGHT.
572814
FLIGHT
Okay. 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.
572820
GNC
Roger, 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.
572829
FLIGHT
Yeah, well the CMC doesn't matter.
  • The SCS can perform an ATT HOLD without input from the CMC.
572835
GNC
Okay, we'll work on it, FLIGHT.
572835
EECOM
FLIGHT, we're not going to have anything in about 40 minutes here.
572850
EECOM
FLIGHT, EECOM.
572856
EECOM
FLIGHT, EECOM.
572858
FLIGHT
Go ahead.
572859
EECOM
Okay, 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.
572905
FLIGHT
Alright. But we're charging BATTERY A.
572907
EECOM
Well, that doesn't mean much in 18 minutes, though. But we're doing all we can do.
572910
FLIGHT
Alright. CONTROL and GUIDANCE, one more time.
572914
GUIDO
Go ahead.
572915
CONTROL
Go, FLIGHT.
572915
FLIGHT
Will it do any good at all to - TELMU, FLIGHT -
572919
TELMU
Go, FLIGHT.
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?
572931
TELMU
Standby.
572932
FLIGHT
The 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.
572940
FLIGHT
And we get a tradeoff here as to whether we can stand that kind of power.
572945
TELMU
Standby 1, FLIGHT.
572947
FLIGHT
Alright. Pronto.
572957
GNC
FLIGHT, 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.
573014
FLIGHT
Oh, okay, RCS SELECT -
573015
GNC
Right.
FLIGHT
RCS SELECT ?? check.
573027
FLIGHT
EECOM? Any need to dump water?
573034
EECOM
Negative on that, FLIGHT.
573036
FLIGHT
No sweat there, Jack.
  • CAPCOM Jack Lousma, still on shift since before the accident.
573046
EECOM
FLIGHT, EECOM.
573047
FLIGHT
Go ahead.
573048
EECOM
They get the POWER AMPL off? I heard them talking about it a while ago. I don't know.
573051
INCO
No, they don't.
573053
EECOM
We can eliminate that central in the 85 foot gainway.
573057
INCO
That's not exactly true -
573059
EECOM
Okay.
INCO
We're looking at it to see how far down we can go.
573102
FLIGHT
Alright.
573103
EECOM
I believe GNC has got some things we can turn down here.
573106
FLIGHT
Yeah, he just - AUTO RCS in Quad Charlie can go off; we've got that Quad PROP ISOL'd. Which I didn't know, but.
573112
EECOM
Pardon?
573113
FLIGHT
Quad Charlie AUTO RCS - GNC, FLIGHT.
573117
FLIGHT
GNC, FLIGHT.
573119
GNC
Go ahead, FLIGHT.
573120
FLIGHT
Confirm: Quad Charlie is PROP ISOL'd off, right?
573124
GNC
Well, we haven't confirmed that, FLIGHT, but it appears that that's the situation we're in. The shock of the O₂ thing, it probably closed those valves -
573135
FLIGHT
Oh, you think -
GNC
- and we haven't been able to open them because those are powered off of MAIN B.
573140
FLIGHT
Mm. Okay.
573141
GNC
But A appears to be working okay.
573143
FLIGHT
Okay. 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.
573154
CAPCOM
Yeah - you want AUTO RCS OFF on Charlie?
573156
FLIGHT
Uh huh.
573157
CAPCOM
How about antennas? How are we doing? Did I hear them give me some bad COMM there?
573202
INCO
We're in pretty good shape right now, FLIGHT.
573204
CAPCOM
Okay.
573205
FLIGHT
EECOM, FLIGHT.
573206
EECOM
Go ahead, FLIGHT.
573207
FLIGHT
Let 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?
573217
EECOM
We 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.
573224
FLIGHT
Okay, now why is that? Tell me why.
573227
EECOM
It's because the numbers we're looking at indicate that it's essentially ambient.
  • Pressure-wise.
573233
FLIGHT
Hold on.
573235
FLIGHT
Okay.
573239
FLIGHT
GNC, watch we don't pick up any rates now, will you please?
573242
GNC
Okay, FLIGHT.
573252
FLIGHT
EECOM, FLIGHT.
573254
EECOM
Go, FLIGHT.
573254
FLIGHT
How long have we got now in the cell?
573256
EECOM
Last account we had 18 minutes, let me get an update.
573258
FLIGHT
Okay. TELMU, what have we got to do to power up to get some COMM on the LM?
573302
TELMU
Okay FLIGHT, we've got a procedure here that gets power up first on the LM.
573314
FLIGHT
Yeah. EECOM, FLIGHT.
573316
EECOM
Go, FLIGHT.
573317
FLIGHT
Yeah, that gets us power but what do you want up? Just the COMM?
573321
EECOM
We'll have to have an environment for the crew, the way this can be -
573323
FLIGHT
That's what I'm asking you, EECOM and TELMU. We've got to figure out how - we're just about out of CSM talkin'.
573330
TELMU
Okay.
573331
FLIGHT
What do you want them to power up in the LM?
573333
TELMU
Standby 1.
573335
EECOM
FLIGHT, EECOM -
573335
FLIGHT
