Spacelog Apollo 13

Yes.

Hey, Fred. John says you can use the dikes on it to get them apart.

Yes, that probably wouldn't have crumbled them as badly.

I generally don't use the subtle approach. You can tell we're feeling pretty good, Vance, when we start complaining about the food.

Yes. That's good to hear.

Aquarius, Houston.

Go ahead.

Fred, we have you on the Goldstone big dish now, and our COMM is much better. If you'd like would you turn the BIOMED switch on to either crewman there.

Okay. Stand by. I'll have to plug in first.

Okay.

Okay, Vance. How do you read on baseband.

We read you just—Stand by.

Okay, Fred. We're receiving your MED data; it was a little slow in coming in.

Houston, Aquarius. Are you calling?

Negative. No call from here.

And, Vance, this is Aquarius.

Go ahead, Fred.

Okay. Jim's coming back on the line, and I'll be unhooking on the BIOMEDs, and you want us to go back to the SPA DOWN VOICE BACKUP?

Stand by.

Okay. Jim doesn't have his BIOMED rigged on right now, so … DOWN VOICE …

Okay, Fred. You're too weak on that last. I understand you're disconnecting, and your BIOMED will be off. Say again about Jim, please.

Okay. How do you read now?

Okay.

Okay. All I said was Jim doesn't have his BIOMED rigged right now so I'll go back to DOWN VOICE BACKUP SPA and Jim's coming on the line.

Okay. We copy you're in DOWN VOICE BACKUP.

Well, I'm thinking about the last 10 hours. We've lost our suit compressors.

Because we don't want to use the power.

Well, that's what I'm saying. We can use these fans right here and use the circulate air right through the use of those fans.

Are we on mike now?

Hello, Houston; Aquarius.

Roger, Jim. Good morning.

Good morning, Vance. How's things going down there?

Oh, quiet and smooth.

Oh, it's afternoon down there.

Right. We thought maybe it was morning to you.

Well, I've sort of lost track. But I had a good sleep.

Glad to hear it. Doctor just said he wondered how many hours?

Oh, let's say whenever I left Jack, and Fred came up and we ate for about an hour, and then I went to bed, so whatever that time was. It must be about 5 hours, something like that; 4 or 5 hours.

Good. Glad to see you catching up.

Aquarius, Houston.

Go ahead, Vance.

Jim, the next time that it's convenient, could you get the readout of the REPRESS package in the command module for us? Over.

Will do.

Okay.

When you go back there, Fred, they want the REPRESS package readout.

We don't want you to wake anyone up to get it.

No. No one's asleep now.

It has? …, was it? … you get forward to it and a pretty good view of the venting.

And, Houston, Aquarius. It looks like service module venting has ceased, at least momentarily.

Roger. Understand service module venting has ceased momentarily. How about the descent stage? Does Fred report venting down there? Do you still see that?

Stand by.

What is your report on descent stage venting—Was it venting? Anything else going on? Any more venting?

No.

No. Fred hasn't seen anything else from the descent stage. And I understand that we can expect the—the SHe—tank pressure to build up to relief here about 105 hours.

Roger. A little later than that—like 106—107.

Okay.

Did you get some interior photos?

Yes.

Okay. I'd like to show them the arrangement of these hydroxide canisters. Do you have?

Aquarius, Houston.

Did they give Jack any more procedures on command module powerup?

…

Did they give Jack any more procedures on command module powerup?

Well, they think it might be up here.

Okay.

The main thing we got to think about, and when we have to get to them, is the procedures for LM jettison, the transfer of the LM to CSM mode (cough), LM jettison.

…

Yes.

… the LM mode?

All we have to do is turn the BIOMED … on, and we'll be in there.

Houston, Aquarius.

Roger. Go ahead, Aquarius.

We would like permission to turn the BIOMED on to get off the hot mike mode. I don't think that we have to be on it now if you have the big dish on, do you?

Yes. Yaw's coming—or roll's coming up for it, and we were going to burn.

Roger, Jim. We concur. Go ahead and turn it on.

Okay. Fine; thank you.

One other point. The philosophy of timing this midcourse is based a little bit on doing it just before the SHe tank is supposed to vent. That way, we hope that we would have — be powered up and you would have control when the venting occurs, in case you were tossed around a little bit. Over.

Okay. Understand. Philosophy on the midcourse is doing it prior to venting of the SHe tank, which means we'll be doing this around 105 hours, I suppose, or 105:30 and so I'll have control of the spacecraft if it should give us some perturbation.

Roger. Then, after that, we would establish PTC again.

Houston, Aquarius.

Go ahead, Aquarius.

Our REPRESS package pressure is 820.

Aquarius, Houston.

Go ahead, Houston.

Jim, could you switch your BIOMED switch to the position opposite to where it is now? We are getting a subcarrier, but no data. Over.

Now you know, Houston, I don't have BIOMED on.

Okay. And we have a small addition to the procedure that was read up to you earlier, which involves power transfer from the LM to the CSM.

Stand by 1.

Okay.

Okay, Houston. Go ahead.

Okay. At the end of the procedure, after the step BAT 5 and 6, OFF, add the following: circuit breakers, panels—panels 11 and 16, ASCENT ECA CONTROL, both open. Over.

Okay. After the step BAT 5 and 6, OFF, step 3 will be circuit breakers panels 11 and 16 ASCENT ECA CONTROL, both open.

That's correct, Jim. And this is to guard against a single-point failure that—a remote possibility that would preclude you from getting the batteries back on.

Roger.

Houston, Aquarius.

Go ahead, Jim.
