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.

…

Fred, Houston. We'll have to stand by for 1 minute. We are in a noisy state of COMM.

Houston, Aquarius.

Aquarius, Houston. Go ahead.

What do you read down there for partial pressure CO₂?

Oh, let's see. We're reading 6.6 right now, Fred. What do you read?

I'm reading about 12.5. I guess we've got a gage problem … I did just get a MASTER ALARM and no caution light; we kind of figured that's what it was, with CO₂ approaching its limit. Maybe it didn't quite come out here.

Okay. Let me get a go, and I think it's time for us to go ahead and put these other canisters on. Stand by 1.

Okay. We went to 15 on the primary last night before I changed it and —

Roger that, Fred. We wanted to —

— I don't have a steady—I don't have a steady ECS light on at this time, Joe, so it must have just been a momentary.

Okay. We know when you went to 15 last night on primary. We want to switch out today at 7.6. Let me check and see if we're ready.

Okay.

Yes. That's what it is, Joe. I've got something going on this alarm … ECS light.

Fred, Houston. The COMM isn't too sharp and I didn't copy.

Okay, Aquarius; Houston —

Houston, Aquarius. How do you read?

— Why don't you try it now? You're loud and clear now, Fred.

Okay. I was just—I'm getting MASTER ALARMS every few seconds and I am catching a glimmer now of the ECS light. For the time being, I have …—… open. Okay, now we got the ECS light on steady.

Okay. Copy that. You have the MASTER ALARM, with the ECS light. We are ready to go ahead and get you on the command module canisters. And as the first step, I'd like to know whether you've inserted the commander's red hose to the second canister bag. Over.

Okay. Yes. Sure enough; the commander's red hose is inserted into the canister bag.

Okay, Fred. The next thing I'd like you to do is to take some more gray tape and tape over half the outlet area of each of the blue nozzles; the commander's and the LMP's. The reason we're doing this is we're going to be running this loop through the secondary LiOH canister hole with the canister removed, and we don't have the flow restriction we need to keep the separator from overspeeding. Over.

Okay. Yes, that's right. So we want to tape over half of the—both the blue and the red commander hoses. Is that right?

Negative, Fred. That's half of the commander's blue hose and half of the LMP's blue hose—the outlet hoses.

Oh, okay. I'll tape over half of each of the outlets. Stand by.

Okay. I'm going to turn off one suit flow valve at a time while I am doing the taping, Joe.

Say again, please, Fred.

Okay, while I'm doing the taping, I'll have that particular suit flow valve in the suit DISCONNECT position momentarily.

Okay. How do you read now, Joe?

Okay, Fred. Reasonable COMM. Are you ready for the next step? Over.

Okay. One correction—the red hose that's connected up right now to the lithium cartridge in the LMP's—Wait a minute.

Okay, Fred. Understand only the LMP's red hose is actually plugged into the canister bag. In that case, we would like you to follow the procedure for inserting the other red hose in the other canister bag as follows: you cut a diagonal hole in one corner of the bag. Look at the other bag and see how it was done. Stick the hose in about 6 inches. Try to get the outlet nozzle down if you can, or else sideways, and then just tape up the hose to the bag to make a nice tight seal. Over.

Okay. Jack's back in here. I guess he can do that. Stand by.

Okay.

How do you read, Joe?

Okay, Fred. Is that done? Over.

No. That's still in works. I just wanted to comment you might pass on to Steve Grega, we thank you a lot for those rendezvous procedures. They went to making up these little boxes.

Okay. We appreciate your appreciating it. We're just having a ball down here working on all kinds of new procedures, Fred. The CPCB is in session, and we expect to have your entry procedures out here by Saturday or Sunday at the very latest.

Saturday or Sunday?

At the very latest!

Take your time, Jack.

Why don't you run that other hose back up in the tunnel so Jim can get some air.

And Joe, how you read now?

Satisfactory, Fred. Go ahead.

Okay. Back to the condensate container. I guess the only question I really need answered is will it leak?

Is will it leak? Oh, yes. Stand by 1.

And we've checked all the fittings and I know I can hook everything up to our UCDs. So, if it doesn't leak, we can transfer.
