Jim, we have some status information for you, if you're ready to copy on a piece of scratch paper.
-
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?
-
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.
-
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.
-
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.
-
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)
-
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.
-
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?
-
Fred Haise (LMP)
-
It's decreasing now. It'll—it'll—It's cold. I noticed that in the command module. It'll wobble.
-
Jack Lousma (CAPCOM)
-
That's affirmative, if you'll take out your contingency book and turn to page Power 6. Over.
-
Jack Lousma (CAPCOM)
-
And while you're doing that, let's put ATTITUDE CONTROL, three, switches to 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)
-
Okay, now, Jack … We have put the TCAs in for the previous procedure. Do you want those out, now?
-
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)
-
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.
-
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.
-
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)
-
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.
-
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)
-
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. And I'm closing the HEATERS on panel 4, QUAD 1 through 4, OFF.
Expand selection down Contract selection 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.
-
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?
