Spacelog Apollo 13

Okay. Let us talk it over a second, and we'll tell you what to do.

Jim, is the battery light kind of flickering?

Yes. That's affirm, Jack.

Yes. The battery light's flickering, and it triggers off the MASTER ALARM.

Okay. Well, that—temperature sensor on battery 2 is kind of cycling back and forth and every time it does, it triggers a MASTER ALARM, Jim.

Okay. Same old problem, huh?

Yes.

And, Jim, finally on the P52, we're considering using the—the Moon and then the Sun for the fine aline.

Okay. The Moon and the Sun for the fine aline. Understand. We'll go through this again here …

Okay, Jack. Once—Once I get the spacecraft at the proper attitude …

Jim, I didn't copy your last question due to background noise.

Okay. Once—Once you get the AGS ball alined … command module …

After we do the body axis aline on the AGS, we can tell you what attitude on the AGS ball to fly to in order to point the CSM optics at the Moon or at some star. And then we can, knowing where the optics are pointed, give you an equivalent set of CDU angles to put in NOUN 20 to torque the platform.

Okay. I see.

That's the current thinking. It may change between now and tomorrow, but right now, that's the way it looks, Jim. It'll probably be some take-off on that anyway.

Okay. Are they planning on a G&N entry or using another system, like EMS or something like that?

It will be a G&N entry.

Nothing like going first class.

Jim, are you broken into the food locker in the LM yet?

That's affirm, Jack. I sure have. … away.

You say you did find everything in order in there, huh?

Yes, everything was great.

Okay. I'll pass it.

I had a question about that earlier.

Right.

Houston, Aquarius.

Go ahead.

I understand that one of your reasons for a suited entry is the fact that the command module hatch … hasn't been good. It doesn't seem to be any different, but in the other … our hatch is no better than other spacecraft.

No, the situation, Jim, is that your hatch is as good as any other hatch but that we won't have a chance to verify it until so late in the game, like 1 hour before entry interface, in this case; whereas before, why, we had a chance to evaluate it in lunar orbit. Over.

Oh, okay.

And that might make your time line a little too crowded, getting your suits on there at the last minute; say, less than an hour before entry interface.

Okay.

Jim, the next action item we want to pursue is transferring some LM power up to the command module MAIN B so we can start charging battery, and I guess what we ought to do is start on that one when somebody else gets up to help you there. So, when you decide to get the other guys up, or to have someone help, why, let us know and we'll start working on that.

Okay. I'll let you have Jack, and Fred's … When in the time line …?

Say again, Jim. I didn't catch that.

When in our time—What's the GET do you plan on …

Jim, I didn't catch all of what you said, but I think you wanted to know when the procedures [on] entry are going to be available and read up to you. If that's the case, why, we're talking about 120 hours or so. As far as the—charging battery A, we want to do that as soon as the other guys get up to help you. We've already passed up some of that procedure, and we have a couple of DELTAs to it.

Roger. Jack's already up. He asked … curious when you wanted to do it. Did you understand that? … Is that correct?

Jim, we're having trouble hearing you. The next order of business is to charge battery A, and when you get somebody to help you there, why, we'll go ahead and get done with it.

Okay. Sounds good.

And, before you start working on it let us know, because we've got some DELTAs to the battery charging procedure.

Roger. I'm putting Jack on the line now to copy down the DELTAs …

Yes. If you'll get that out, I'll read you the DELTAs.

Okay. I've got it.
