Vance Brand (CAPCOM)

Jim, we have some status information for you, if you're ready to copy on a piece of scratch paper.

Fred Haise (LMP)

Put that away and get some status paper here.

Vance Brand (CAPCOM)

Okay. First, midcourse correction will probably be at GET 104 hours, and all we look for is a 4- to 6-feet-per-second DELTA-V. Okay. That's the first item. Now, I will give you a rundown on consumables. Okay. In the LM, you have 1498—that is 1 4 9 8 amp-hours remaining. That means over 61 hours you'd—That would average out to 24.5 amps. We expect that, after powerdown, that you will use 1 4 or 14 amps per hour, and that would leave a reserve of 500 amp-hours at the end of the mission. Are you with me?

Jim Lovell (CDR)

Roger. We're with you.

Fred Haise (LMP)

I saved my—number was yesterday.

Vance Brand (CAPCOM)

Okay. In the LM, you have —

Vance Brand (CAPCOM)

Roger. In the LM, you have 215, that is 2 1 5, pounds of water, usable. That would average out over 61 hours to 3.5 pounds per hour available. Okay.

Vance Brand (CAPCOM)

Okay. And after you power down, we expect that you will be using water at the rate of 3.2 to 2.7 pounds—That's at 14 amps per hour electrical usage rate. One note, this does not—When we speak here of water available, this does not include CSM water and PLSS water, so that's add on. Okay, next, LiOH. Using the CSM cans, you will have 16 cans at 12 hours per can to give you 1 9 2, or 192 hours, of LiOH. And, in the LM, using its cans, you have 44 hours remaining.

Jim Lovell (CDR)

Vance, is that with the PLSS secondaries?

Vance Brand (CAPCOM)

That's affirm. That's affirm. That includes PLSS secondaries.

Vance Brand (CAPCOM)

Okay; oxygen. You have remaining 44 pounds in the LM. At a usage rate of 0.36 pounds per hour, that leaves you 120, or 1 2 0, hours of oxygen. Okay. Next, RCS. RCS A stands at 6 2 percent and B at 6 2 percent. We only expect 2 percent to be used for the PTC, so you're in good shape for RCS. Next, DPS DELTA-V. You have 1190 feet per second remaining. And, finally, CSM EPS. We estimate that you have 99 amp-hours. That's an estimate. And that's it. Over.

Vance Brand (CAPCOM)

Okay. And just a question. It would be interesting to hear from Jack to see if he thinks that main B bus is good. If he has any idea of how, if whether it's good or not, this would influence our steps in the future; for example, we might want to try to test main B to see if it is, in fact, good so that we'd know how to set switches for entry.

Jim Lovell (CDR)

Roger. Just a minute. They want to know whether you think main bus B is any good for the command module.

Jim Lovell (CDR)

Vance, while Jack's got on the loop, let me pose the question of how we're planning on doing this midcourse, if we are going to power down the PGNS.

Vance Brand (CAPCOM)

Would you stand by on that, Jim? We'd like to give you a procedure for that later on.

Jim Lovell (CDR)

Okay. Got a midcourse at 104 hours, he's going to give us a procedure for that later on.

Vance Brand (CAPCOM)

In short, Jim, we don't expect any problem, but we'll explain further later on.

Vance Brand (CAPCOM)

Deke says get a night's sleep. He says you've been working hard, and you ought to relax a little bit and be ready for tomorrow.

Jack Swigert (CMP)

Okay. Let me give you my observations on main bus B. Things happened pretty fast there, and we first heard the impact or explosion or whatever caused it, I'm not sure. The next—About 1 second later, there was a MASTER ALARM which was the MAIN BUS B UNDERVOLT. I looked at the voltage, and the voltage was good at this time so I'm suspecting it was a spike. Fuel cell 3 was also good, with good flow. However, Fred, at that point, was coming into the command module and got over into his seat. At that time, we shortly had an AC BUS 2 light about the time he got into his seat. He looked at the MAIN BUS B and the MAIN BUS B was reading ZERO. It, however,—and the fuel cell flows were ZERO. I'm kind of suspecting that perhaps we do have a MAIN—a current MAIN BUS B. But that's merely a guess. I never did try to reset it. We were having other problems with the MAIN BUS A, having an UNDERVOLT and a few other things like that. I'd kind of like to hear what your feelings are down there.

Vance Brand (CAPCOM)

Well, Jack, we copy your information. And we'd like to hold off because we're still working the problem. So we'll have to give you information later.

Vance Brand (CAPCOM)

Aquarius, request AFT OMNI.

Jack Swigert (CMP)

Vance, are you back with me?

Jack Swigert (CMP)

Okay. We lost lock there. We switched OMNIs. Just for my own—kind of to get my thoughts in order, I'd kind of hear what—I'd like to hear what kind of entry you're planning. EMS or PGNS or what ?

Vance Brand (CAPCOM)

Okay. PGNS entry is being planned, and people are at work on checklist changes and that sort of thing.

Vance Brand (CAPCOM)

And—we'll—We'll give you the CSM stuff tomorrow, but basically we expect that main bus B is good and we're going to work up a procedure to test it.

Jack Swigert (CMP)

Okay. Those are my thoughts, too.

Jack Swigert (CMP)

You think main bus B is good, don't you?

Vance Brand (CAPCOM)

That's affirm.. We think it is, but we want to check it out anyway. We think you guys are in great shape all the way around. Why don't you quit worrying, and go to sleep.

Jack Swigert (CMP)

Oh, that—That's our boss, Deke.

Jim Lovell (CDR)

Well, I think we just might do that—or part of us will.

Jack Swigert (CMP)

I mixed up. How many more of those—Are we hot mike? —

Jack Swigert (CMP)

Yes, I'm mixed up. You had 15? I mixed up seven more. So we got 22. By the way, there's still some water that's- it's not enough pressure to mix up another drink, but there is some water out of there, if you want to get some water out of the drink cup.

Fred Haise (LMP)

That's good; I could use some.

Jack Swigert (CMP)

We ought to use that oxygen up and not waste it. (Cough)

Jim Lovell (CDR)

What'll it take to …

Fred Haise (LMP)

You only got two … there, so …

Jack Swigert (CMP)

You wouldn't believe it, but I'm now in command of the LM. Okay. Vance, I'm probably the only CMP that's ever witnessed a DPS burn sitting on the ascent engine head.

Fred Haise (LMP)

Did you get some? Is there any coming out still? They didn't answer. I think we made it. How's this working out?

Jack Swigert (CMP)

They are, huh? How are we going to get an alinement?

Jim Lovell (CDR)

We'll pull one out someways, I guess. We've gotta watch that one right there.

Fred Haise (LMP)

It's decreasing now. It'll—it'll—It's cold. I noticed that in the command module. It'll wobble.

Fred Haise (LMP)

Switch OMNIs to TRANSMIT.

Jim Lovell (CDR)

Roger. Are you planned to set up here very shortly—a powerdown procedure?

Jack Lousma (CAPCOM)

That's affirmative, if you'll take out your contingency book and turn to page Power 6. Over.

Jim Lovell (CDR)

Roger. Stand by. Contingency Power 6. Get the book over here. Contingency Power 6.

Fred Haise (LMP)

Well, I hope this …

Jack Lousma (CAPCOM)

And while you're doing that, let's put ATTITUDE CONTROL, three, switches to MODE CONTROL.

Jim Lovell (CDR)

All three ATTITUDE CONTROL switches have been in MODE CONTROL.

Jack Lousma (CAPCOM)

Okay. And when you get to Power 6, you ought to see a circuit breaker page, panel 11.

Jim Lovell (CDR)

Have a pencil? Let's see it—thank you.

Jim Lovell (CDR)

Okay. I have Power 6, panel 11.

Jack Lousma (CAPCOM)

Okay. On Power 6, panel 11—The top three rows, configure them as you see them.

Jim Lovell (CDR)

Okay, now, Jack … We have put the TCAs in for the previous procedure. Do you want those out, now?

Jack Lousma (CAPCOM)

That's affirmative, Jim, Pull them out. TCAs open.

Jim Lovell (CDR)

Okay. I'm changing those to … back again. First three rows. And you're pulling the ATCA PGNS, huh?

Jack Lousma (CAPCOM)

That's affirmative. Pull ATCA PGNS open.

Jim Lovell (CDR)

Okay. I've done that.

Jack Lousma (CAPCOM)

Okay. Are you ready for the fourth row?

Jack Lousma (CAPCOM)

Okay. Now when we get in the fourth row, we're going to open the IMU OPERATE circuit breaker; and what that means is that we're going to lose the capability to watch your CDUs, so we're not going to be able to see your attitude. Therefore, we will not be able to advise you on which antenna to select for communications. The way we want you to handle that is to turn the LM UPLINK SQUELCH off, and when you hear the noise, switch antennas. We'll be able to see you switch antennas, and it's going to take us about 3 to 5 minutes to establish a lockon again after you switch. After each time that you switch antennas, we will initiate a voice check. And basically when you see the Earth out the window, you can be on FORWARD antenna, and when the Moon's up in the window use the AFT antenna. You copy?

Jim Lovell (CDR)

Okay. We're going to pull the IMU OPERATE circuit breaker, so you won't be able to see our attitude. Therefore, you won't tell us how to switch antennas and we'll enable the—I will turn the—up the SQUELCH OFF so that when we start getting any static, we'll switch antennas and as a thumb rule we could use—with the Earth forward, we use the FORWARD antenna and when we see the Moon we use the AFT antenna.

Jack Lousma (CAPCOM)

That's affirmative, Jim. In other words, we're leaving the antenna switching up to you, and after you switch antennas it's going to take 3 to 5 minutes for us to establish a lockon again, and we'll initiate a voice check. And I'm ready to go on panel 11, row 4.

Jack Lousma (CAPCOM)

Okay. On row 14, under HEATERS RCS SYSTEM A/B-1: open QUAD 1 through 4; under ECS, the only change is—under GLYCOL PUMP close AUTO TRANSFER; under COMM, the only change is: open VHF A RECEIVER, open COMMANDER AUDIO; under PGNS, the only change is: close and leave closed IMU STANDBY circuit breaker, so we can have heaters. Read back.

Jim Lovell (CDR)

Okay. On row 4, we're going to open all four of the heaters—the RCS SYSTEM A and B—the first four circuit breakers. We're going to close the AUTO TRANSFER. We're going to open the VHF A RECEIVER and the COMMANDER AUDIO. And we're going to close the IMU STANDBY. The LGC DSKY and the IMU OPERATE will be open.

Jack Lousma (CAPCOM)

That's affirmative, Jim. All other breakers in that row are as you see them in the checklist. And on row 5, the only change is that we want you to, under EPS, open ASCENT ECA CONTROL. Over.

Jim Lovell (CDR)

Roger. I think we already have that opened—ASCENT ECA CONTROL is probably already open.

Jim Lovell (CDR)

Okay. So let me confirm. We'll have one COMM system, that will be the LMP system, and we'll have to do our own antenna switching; therefore, we'll have to wait about—Okay, why don't you switch? Aft antenna.

Jim Lovell (CDR)

We'll have to wait for you to get a lockon again. Is that correct?

Jack Lousma (CAPCOM)

That's affirmative, Jim. You'll be working off of the LMP's panel over there.

Jim Lovell (CDR)

Okay. What else do you have for me?

Jack Lousma (CAPCOM)

Okay. Panel 16, that's on page Power-7. Top row, the only change is: under RCS SYSTEM B, open PQGS/DISPLAYS. Over.

Jim Lovell (CDR)

Okay. I may go over this with you, Jack, because this checklist has been written over two or three times now on our various procedures. Top row, the first two are open, the next three are closed, and we're going to open now the QUAD TCA's 1, 2, 3, 4; CROSSFEED will be closed, and the TEMP/PRESS DISPLAYFLAG will be opened, and we're going to open up the PQCS, MAIN SOV will be closed, and the … will be opened.

Jack Lousma (CAPCOM)

That's affirmative, Jim. And there's no change to the second row. Over.

Jim Lovell (CDR)

Okay. Again let me go through this with you. The first four are going to be closed. The next sev—eight will be—the next nine will be open from LOGIC POWER B through DESCENT ENGINE OVERRIDE How about the CWEA? Is that going to be closed?

Jack Lousma (CAPCOM)

That's affirmative, Jim. We want the next five closed.

Jack Lousma (CAPCOM)

Okay. In the third row, under COMM: DISPLAY, open; SE AUDIO, closed; VHF A TRANSMITTER, open—That's a change—VHF B RECEIVER, open; PRIMARY S-BAND, POWER AMPLIFIER, open; TRANSMITTER/RECEIVER, closed; S-BAND ANTENNA, open; PMP, closed; TV, open. Under ECS: DISPLAYS, open; GLYCOL PUMP SECONDARY, open; LOC PUMP, open; CABIN FAN CONTROL, open; CABIN REPRESS, closed; and all the next four closed also. Read back.

Jim Lovell (CDR)

Okay. We have DISPLAY, open; SE AUDIO, closed; VHF A TRANSMITTER, open; VHF B RECEIVER, open; POWER AMP's going to be open; TRANSMITTER/ RECEIVER, closed; S-BAND ANTENNA, open; PMP, closed; TV, open; DISPLAY is open; next three are open; CABIN REPRESS, closed; and all the rest closed.

Jack Lousma (CAPCOM)

That's affirmative, Jim. And in row 4, under HEATERS, we want them all—Correction—we want all the QUAD HEATERS open. Correction—we want all the QUAD HEATERS closed.

Jack Lousma (CAPCOM)

We want DISPLAY, open; S-BAND ANTENNA, closed—to avoid a MASTER ALARM, CAMERA—SEQUENCE CAMERA, open; And under EPS, we want DISPLAYs, open; DC BUS VOLT, closed; INVERTER 2, open; ASCENT ECA, closed; ASCENT ECA CONTROL, open; DESCENT ECA, closed; DESCENT ECA CONTROL, closed; TRANSLUNAR BUS TIE, close; we want the CROSS TIE BUS, open; the BAL LOADS, closed; BAT FEED TIEs, closed. How do you read?

Jim Lovell (CDR)

Okay. The four RCS HEATERS will be closed; DISPLAYS, open; S-BAND ANTENNA, closed; CAMERA SEQUENCE will be open; DISPLAY will be open; DC BUS VOLT will be closed; INVERTER 2 open; ASCENT ECA will he closed, but the ASCENT ECA CONTROL, open; DESCENT ECA, closed; DESCENT ECA CONTROL, closed; TRANSLUNAR BUS TIE, closed; and CROSS TIE BUS, open; and BALANCE LOADS, closed; and the BAT FEED TIEs, closed. I have one question, Jack. On panel—on the second line there under LIGHTING, why are we keeping: the FLOODS and TRACK closed? Or are they going to be open?

Jack Lousma (CAPCOM)

Negative. We have the, LIGHTING breakers all closed. Control the lighting with the switches and rheostats. Over.

Jim Lovell (CDR)

Okay. We don't need the floodlights, I don't think, but we can do it that way, I guess.

Jack Lousma (CAPCOM)

And under row 4, under RCS SYSTEMS A/B-2, QUAD HEATERS, you notice that we've closed those circuit breakers, but what we want you to do is to—on panel 3, turn the RCS A/B-2 QUAD switches 1, 2, 3, and 4, off. Over.

Jack Lousma (CAPCOM)

And we're going to watch your quad temps for you, and when we need to warm them up a little bit, we'll tell you to throw those four switches on—on panel 3.

Jim Lovell (CDR)

Okay. Now are we sure that this PTC mode is good enough so we don't … get crossed up later and get out of configuration.

Jack Lousma (CAPCOM)

Stand by 1 on that, Jim. Okay, Jim, as far as we can tell right now, the PTC looks as good as any PTC we've ever seen in a CSM, so we're going to go with what we've got.

Jack Lousma (CAPCOM)

Okay, and if you turn over the page on Power 8, we have the spacecraft functions remaining to you. We've got low bit rate TM. However, we don't have any VHF. We have CWEA. We have GLYCOL PUMPS. We have SUIT FANS. We have CABIN REPRESS for you, and stand by in ATTITUDE CONTROL here. Okay, in ATTITUDE CONTROL, we'll have hardovers for uses in emergency, and for normal usage we want to have a 15-minute delay to get the heaters on to warm them up be before use. How do you read?

Jim Lovell (CDR)

Okay. For emergency, we have the hardovers and for normal use it requires a 15-minute request to get the heaters on.

Jack Lousma (CAPCOM)

Okay, Jim, that concludes our powerdown procedure, and we're waiting for you to get with it.

Jim Lovell (CDR)

Okay, Jack, we'll start. I sure hate to lose the PGNS. I sure hope that procedure for the midcourse is a good one.

Jack Swigert (CMP)

You want me to help you here?

Jim Lovell (CDR)

Yes, you can—Okay. First we power down, panel 11. All of them open.

Jim Lovell (CDR)

Stand by for a MASTER ALARM. …

Jim Lovell (CDR)

I'll give you this when I'm finished. After we go through this, then you can go through it again and doublecheck it.

Jack Swigert (CMP)

Now, the flood lights are on, right? No, I kind of don't think we need them though, do you?

Jim Lovell (CDR)

Don't pull those. Give me the—first of all. We'll get back there. Those four are close, open, open, ENGINE ARM, open, …

Jim Lovell (CDR)

Say, Houston; Aquarius.

Jack Swigert (CMP)

It will take him a minute to …

Jim Lovell (CDR)

You're familiar with our particular spacecraft that on panel 16 HEATERS RCS SYSTEMS A and B, QUAD 1 HEATER circuit breaker has been pushed in, and sealed in, and if it's ever pushed out, it's doubtful if we'll ever be able to reset it.

Jack Lousma (CAPCOM)

Okay, Jim, on the four QUAD HEATER breakers, we want you to leave them closed. And we'll operate the heaters with the switches on panel 3. Over.

Jim Lovell (CDR)

Okay. We'll do it right there.

Jim Lovell (CDR)

Okay. And I'm closing the HEATERS on panel 4, QUAD 1 through 4, OFF.

Jack Lousma (CAPCOM)

Okay. It's time for you guys to get to bed and get Fred up.

Jim Lovell (CDR)

(Laughter) I still have one question, Jack. I still think that—I still say that the—on the LIGHTING in our panel 16, the FLOOD lights and the TRACK should be open. We're not using them.

Flight

Do you have any argument about -

Jack Lousma (CAPCOM)

No problem, Jim. Go ahead and open them, TRACK and FLOOD, that's all right.

Jack Swigert (CMP)

Okay, TRACK and FLOOD are OPEN.

Jim Lovell (CDR)

Now, why don't you go through that, Jack, and make sure those —

Jim Lovell (CDR)

Okay, Jack, my only other concern now is the CO2 rise in the spacecraft. I guess you're keeping a handle on that?

Jack Lousma (CAPCOM)

That's affirmed, Jim. We have you up to 10.6 now, and we're willing to go a little higher on that. We have another cartridge and we have a procedure for making the command module cartridges up. We'll pass that on later.

Jim Lovell (CDR)

Oh, yes. I'm not worried about that. I just wanted to make sure that you —

Jim Lovell (CDR)

— that—We just don't want to go to sleep here and forget about the rise in CO2.

Jack Swigert (CMP)

Are they going to use … —

Jack Lousma (CAPCOM)

Roger. We're watching it for you —

Jim Lovell (CDR)

Yes, they're getting it …

Jack Lousma (CAPCOM)

— We have it here. It's now 10.7 and we have a medical go to 15 millimeters.

Jim Lovell (CDR)

There's a new first for you.

Jack Lousma (CAPCOM)

Okay, Jim, we estimate we've got 1 more hour on the primary cartridge, and 6 or 7 hours on the secondary.

Jim Lovell (CDR)

Okay. Fine. Say, it's a spare primary cartridge back there, too, isn't it? So that's good for another, how long?

Jack Swigert (CMP)

Yes. Yes. That's yours though, isn't it?

Jack Lousma (CAPCOM)

And you're right, Jim. We've got another primary cartridge back there behind the ascent engine cover.

Jim Lovell (CDR)

Right, yes. We know. Thank you.

Jack Swigert (CMP)

Okay. I guess you've done everything right on that panel. Let me check the middle one. Yes. You powered down and then you leave me. Tell me, I've got it.

Jack Lousma (CAPCOM)

Okay, Jack, we just thought it's about time you got a LM checkout.

Jack Swigert (CMP)

But he's giving it to me inert. Of course, I'm giving him my command module, too, which is rather inert right now, too.

Jack Lousma (CAPCOM)

Well, you've got to walk before you run, you know.

Jack Lousma (CAPCOM)

Aquarius, Houston. Over.

Jack Lousma (CAPCOM)

Roger. For your information, Jack —

Jack Swigert (CMP)

You're loud and clear.

Jack Lousma (CAPCOM)

— all of our analysis is based on powerdown to 14 amps, but we're reading on you right now 12.3 and so we're better off than we were in our analysis.

Jack Swigert (CMP)

Jack, I thought you were going to get the sleep shift where there wasn't any excitement?

Jack Lousma (CAPCOM)

Well, I tried, but I didn't make it. I thought you were supposed to he sleeping now.

Jack Swigert (CMP)

Well, Fred-o is getting something to eat, and Jim is starting to sack out so I'm taking the COMM here until Fred gets set.

Jack Swigert (CMP)

As I just—Yes, are you ready to take over? Well, he just—he just asked—said he thought I was supposed to be sleeping. And I told him that I was waiting for you to—Okay. You were off the NET when they explained the—But don't they—Can't we monitor our CDU's any more to tell when to switch antennas, so they've just—When they can see it switch—it will take a couple of minutes for them to get up. And they'll always make a voice check with you.

Jack Swigert (CMP)

It came out here. I caught it. Okay. Now, are you getting squared, I'll give you the COMM here.

Jack Swigert (CMP)

They're, they're showing right now 12.3 amps Their analysis is based on 14 so they're in better—Okay. Headset's yours

Fred Haise (LMP)

Okay, Jack. How do you read?

Jack Lousma (CAPCOM)

Hearing you loud and clear, Fred. OMNI.

Fred Haise (LMP)

I see you luck out with all the good shifts.

Jack Lousma (CAPCOM)

Yes, I got all the good deals. I heard Jack brief you on the COMM mode so, you got any questions about that?

Jack Lousma (CAPCOM)

And how is your PTC going? I heard Jack tell you that we can't see your CDU's. How's it going?

Fred Haise (LMP)

Well, let's see, we may be offsetting slightly, the Sun looks like it may be a little higher now. Here comes the Earth by and it looks about the same perspective. I'll have to wait to see the Moon on the other side, Jack. …

Jack Lousma (CAPCOM)

Okay, Fred, I can't hear you any more on account of the background noise. I assume that—I think I heard Jack tell you what we're going to do about COMM. UPLINK SQUELCH, off. You'll take care of the antennas because we can't see your attitude. We'll give you a voice check when come up. It'll take us 3 to 5 minutes to come up. And to make it astronaut-proof, when you see the Earth, use a forward antenna; when you see the Moon, use the aft one.

Fred Haise (LMP)

Yes, that's pretty straightforward. Okay, I see the Earth so I've very wisely shifted to FORWARD.

Fred Haise (LMP)

Earth will be by over there in a minute.
