Spacelog Apollo 13

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.

Okay, Fred. We still don't have a final answer on whether or not it'll leak. If you need it, I'd go ahead and use it; and standing by for your completion of the hose-insertion procedure.

Okay. The hose-insertion procedure … the second cartridge is complete.

Okay. That's complete. The next step is to switch to the primary CO₂ canister and remove the secondary canister and stow it. Over.

Okay. I'm going to have to get off COMM here; I'll let Jack get the headset.

Okay.

Hey, Joe. I'm on the headset now.

Is that secondary? … secondary?

Both cartridges are out.

Okay, Joe. Fred has the secondary cartridge out. We're back on primary now.

Okay, Jack. The next step is to place the command module canisters with the hoses attached in a suitable location to permit the bottom of the canister to be exposed to free airflow and tape them in place. Ideally, well, it doesn't matter. Just—just pick out your own spot.

Okay. I'm going to tell you where they are. They're both situated, as you say, with the bottom of the canister exposed to free air, and one is sitting right by the—the LMP's is sitting right by the EPS panel, and the CDR's is up in the tunnel.

Jack, Houston. The COMM got real noisy there, and I didn't copy that. Stand by a moment.
