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.
Expand selection up Contract selection down Close -
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)
-
(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?
-
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.
-
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 Lousma (CAPCOM)
-
And you're right, Jim. We've got another primary cartridge back there behind the ascent engine cover.
-
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 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)
-
— 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
-
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)
-
Okay, when I was upstairs, just a minute ago, I noticed what appeared to be some new venting from down the service module way. I noticed that out window 1, and also saw one chunk of metal—loose metal about 4 inches square that was tumbling around—silver in color, and it, looked like it had come from somewhere down in the service module.
-
Fred Haise (LMP)
-
Yes, that's where I happened to be looking. The lighting was such that it showed up out there. What reminded me of it was I'm looking out the LM window now and I sea a good part of the new star field it's created for us. There are about a thousand little sparklies out here.
-
Jack Lousma (CAPCOM)
-
Okay, so you're seeing some venting out window 1, and you saw a 4-inch-square piece of loose metal which was silver, and—Are you still seeing the venting or has it zeroed out now?
-
Fred Haise (LMP)
-
I don't know. I left upstairs, I'm down in the LM now, Jack. I guess when Jack goes up he can take a look and let me know. Okay, I'll think about switching aft here directly. I see the Moon, and the Moon looks pretty good, Jack, so I guess our PTC still doing pretty good.
-
Jack Lousma (CAPCOM)
-
Good, and we want to ask you another question about the venting. Is this—would you suppose—some new venting or is this venting that you just hadn't—that's been going on all the time, but which you hadn't looked at recently?
-
Fred Haise (LMP)
-
I can't really say, Jack, we've been so tied up down in the LM, I guess we kind of forgot about the other half. But I've been upstairs several times and hadn't particularly noticed any flow by the windows before, so I—my first assumption was that it was some new venting. It really wasn't very heavy.
-
Jack Lousma (CAPCOM)
-
Okay. And for your information, all of our numbers are based on amperage usage of 14 amps. And we're using only 12.3, so we're a little fat on our analysis.
-
Jack Lousma (CAPCOM)
-
Well, that's one of several. And we want to tell you something that I told Jim earlier, and that concerns control. Right now you have control in hardover if you need it, but when we go to some normal control modes, since we have the quad heaters off. We want to have a 15-minute notice for attitude control request. Over.
-
Fred Haise (LMP)
-
Okay, Jack. Offhand, I can't imagine that since we got the platform powered down why we'd need to worry about the instantaneous control. But at any rate, we need 15-minutes warmup with the heaters before we can start using thrusters.
-
Jack Lousma (CAPCOM)
-
Right. And another thing we've done is to pull your ECS and EPC DISPLAY breakers and so—But we left your CAUTION and WARNING powered up. So if you get ECS-type or EPS CAUTION and WARNING you'll have to power up those meters with the DISPLAY breakers. And we are watching for you your PIPA temperatures, your ASA TEMP, your propellant temperatures except for the DPS propellant, and we're watching your quad temps for you.
-
Jack Lousma (CAPCOM)
-
And, Fred, your CO2 is building up. It's at 11 on our gage, and we've got a medical buildup to 15 millimeters, at which time we'll switch over to secondary. Looks like we've got plenty of lithium hydroxide, about 192 hours including the CSM cartridges. And as you know, we've got a way to use those. And as soon as we get them written in some good words, why, we'll pass; that along. You might be able to make one.
-
Fred Haise (LMP)
-
Okay. Yes, we'll sure give her a try. And I'm showing onboard about 12-1/2 millimeters of mercury.
-
Jack Lousma (CAPCOM)
-
Roger. And I have a flight plan update when you get a time to copy it sometime, I'll pass it along. There's no hurry on it.
-
Fred Haise (LMP)
-
Okay. Jack just came hack and he said it's still coming out; it's only coming out on the commander's side. So he saw it out the same window I did, window 1. And it's between the minus Y and minus Z axis.
-
Fred Haise (LMP)
-
Jack says it's definitely the service module which was—which was my impression, too.
-
Jack Lousma (CAPCOM)
-
Okay. So you're sure it's the service module, and, of course, the thing we're interested in knowing, is it something that is residual from before, or is it something new. And if you have any ideas about that, why we'd sure like to have them them.
-
Fred Haise (LMP)
-
Yes. Yes, Jack, I'll answer him your question in a minute, but make Jack's first impression here, is that it's not near the intensity that it was right after our mishap. And I'll have to agree with that. I'd say—he said it was a half and I said it was maybe down to a third. And Houston would like to know if you have any impressions as to whether it is still a residual from that or maybe something new.
-
Fred Haise (LMP)
-
I don't know why after I felt that. Yes, I felt it was some new something—new venting, too.
-
Jack Lousma (CAPCOM)
-
Fred-o, if you think it's practical, we're ready to give you some—we're working on some camera settings for pictures of the venting. And, if you have a camera out and ready to go, let us know which one it is so we can get the settings for that camera. What do you think about that?
-
Fred Haise (LMP)
-
Okay. Jack's got the one with the 250-millimeter lens on it. That's the standard EL. And I have a surface camera out that I've been shooting hundreds of Earth/Moon pictures with, camera 1. And we also have the Reseau upstairs that's pretty handy. The command module DC camera. So you can about —

Jack Lousma (CAPCOM)
-
I copy the 250 millimeter, the Reseau is available, but I didn't get what other one is.
-
Fred Haise (LMP)
-
And, Jack, if we're going to do any picture taking out the command module windows, I think we'd better do that pretty quick, or hold up until Jim and Jack get their rest done.
-
Jack Lousma (CAPCOM)
-
Okay, Fred, we're not going to bother the skipper up there. We won't be taking any pictures out of the command module window until after rest period.
-
Jack Lousma (CAPCOM)
-
Okay. Fred, for your information, your CO2 reading onboard is a little higher than what we're reading here on the ground, and so when it gets to 15 on your meter, switch to secondary. And we'd like to get a status about every 30 minutes—we'll give you a call on that. But just to let us know we're still thinking about you, we'd like you to go BIOMED RIGHT, please.
