Spacelog Apollo 13

Okay, Joe.

Okay, Jack. You can go ahead and set up that switch configuration. What we are discussing is having you activate the MAIN BUS TIE motor switches a little later on simply to verify that they will be okay, because the batteries are probably getting a little bit cool. But we'll be back to you with a procedure and discussion about that after you get the switch configuration set up. Over.

Okay, I'm going to go get the switch configuration done now before Jim goes to bed so I don't disturb him.

Okay. Real fine.

Jim thinks Deke sounds like Frank Borman on Apollo 8.

(Laughter) Okay. Sorry about that.

I'm going to give the COMM to Fred-o, now.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

Okay, before I hit the sack, Joe, I just want to make sure—How are you still planning an MCC at 107 and what's the latest find?

Okay, Jim. We are still gathering our thoughts on the MCC, but some of the considerations go like this: FIDO tells us that we can do that correction probably as late as 118 hours, with no significant DELTA-V penalty, and with plenty of tracking thereafter to make sure that we've done the right thing, and to set you up for a late MCC if we need it, which we probably wouldn't. We are happy with the PTC mode that you are in now, and, although we are working up a—an AGS PTC mode to use after the midcourse correction, we'd kind of like you to stay in this PTC for a while because it is doing good. We are looking at the weather in the landing area. We don't think we'll have a problem but we are checking it real close, and if there is any changing that we want to do, we want to get it into this midcourse correction. And for reasons like that, we are considering possibly delaying the midcourse correction from 104 hours to some time between there and 118. We'd like to know what you think about it. Over.

We have no druthers. As long as we do the midcourse and there is plenty of tracking thereafter to correct for another midcourse; that's my only concern.

Okay, Jim. Roger that. And based on FIDO's input that he'd like to do it not later than 24 hours before EI, we will be doing it prior to 118 hours.

Okay.

Hello, Houston; Aquarius.

Aquarius, Houston. Go.

Question, Joe. Jim has been talking to me about how we are going to do this midcourse, and awhile back when we went through this power up, we had pulled the STAB/CONTROL ASA breaker. I was wondering—we lost the heaters in the ASA—I was wondering how it looked? What kind of shape it's going to be in?

Okay. Stand by on that one, Fred.

Okay.

Fred, Houston.

Go ahead.

Roger. I am told that we'd see 38 degrees for that package, and it'll be okay for the burn. We're massaging the detail procedures for this burn at this time and we expect to have a real clean setup to you in plenty of time.

Okay, very good.

And I don't know if Jack passed it on to you, but Jack and I just finished logging about 6 hours sleep, each.

Roger, Fred. Copy that. Is it a little chilly up there?

Yes. We made the mistake of putting up the window shades, which we won't do again; and with this powered-down mode, we're not generating much internally, and it really did get chilly.

Yes. I guess you'll have to generate your own heat in there for a while.

Deke says unstow the Exer-Genie.

Aquarius, Houston. Over.

Go ahead, Houston.

Fred, just wanted to let you know in advance that we're coming up on the redline CO₂ value for the secondary canister, and we expect to get there in something like a half hour, at which time we'll be asking you to switch over to the command module canisters. I have the rest of that procedure ready and I just wanted to warn you a little bit in advance. Over.

Okay. And I've got a question for you, Joe.

Go ahead.

Okay. The—I need to find out if the condensate container that we were going to use to strain some water in on the lunar surface—is that container also completely airtight? Okay to use it to put fluid in through here in zero g?

Fred, I didn't copy what you wanted to use it for. Over.

Okay. It sounds to me as if the suggested receptacle is perfectly satisfactory. Do you think you can use it in its present configuration?

Oh, yes. We got all the innerconnects—hookups we need, but I wasn't sure if that gadget was devised solely with the 1/6g environment in mind, and whether it might leak somehow in zero g.

I'll have them verify that, but off the top of my head, I'm sure it's going to be all right. We'll check it, Fred.

Houston, Aquarius.

Aquarius, Houston. Go ahead.
