Spacelog Apollo 13

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.

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.

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.

All the —

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?

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?

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

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

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.

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.

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.

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.

Okay.

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?

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

That's affirmative.

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

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

It is.

You want me to help you here?

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

Closed.

Yes.

Stand by for a MASTER ALARM. …

Okay.

Here it comes.

Are they going to —

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

Are they going to use … —

Roger. We're watching it for you —

Yes, they're getting it …

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

That's a new one.

There's a new first for you.

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

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

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

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

Right, yes. We know. Thank you.

Yes, yes, I just -

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.

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

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.

Aquarius, Houston.

Aquarius, Houston. Over.

Go ahead, Jack.

Roger. For your information, Jack —

You're loud and clear.

— 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.

That sounds good.

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

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

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.

Okay.

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.

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

I don't know. […]

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

Okay, Jack. How do you read?

Hearing you loud and clear, Fred. OMNI.

Okay.

Okay, I heard the —

I see you luck out with all the good shifts.

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

Okay.

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

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. …

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.

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

Good boy.

Got another battery?

… really sick.
