Spacelog Apollo 13

Aquarius, Houston. It looks like you're proceeding toward the gimbal lock there. We'd like you to check that, please.

Roger. Not much we can do about it. We can't use the thrusters, Houston.

And, Houston, Aquarius. I guess the next thing for the PGNS will be a coarse aline 000, but I guess we ought to hold up now until we get enough time on the RCS thrusters.

Aquarius, Houston.

Go ahead.

Roger. Did you get my GO for RCS?

That's affirm. We're GO. What we're doing now, Jack, is letting the spacecraft drift in this mode to pick up the Earth again.

Okay.

It's going to be interesting today, Jack. The Earth's a lot bigger; the crescent is a lot more pronounced than it was yesterday.

Well, you're going in the right direction.

That's right.

And, Jack, I guess we haven't changed our angle much with respect to the Sun 93 million miles away, so it ought to be in about the same place in the AOT, isn't that Charlie?

Hold 1 on that, Fred. I'll get an answer for you.

Okay.

Aquarius, your ASA is warmed up now. You can activate the AGS.

Aquarius, Houston. When you look out a detent 2 in the proper burn attitude, what you ought to see is the Sun at 12 o'clock, about halfway between the top of the AOT and the center of the pipper. And you ought to see the Earth —

Okay.

— at 6 o'clock.

Okay.

And, it's getting a little warmer in here now. Thank you.

Duck blinds are always warmer, Jim, when the birds are flying.

Right.

Jack, I've gotten so used to flying attitude with the TTCA, I won't be able to do it normally.

Say again, Jim.

Aquarius, we see your glycol temperature getting up there. If you want to make it a little warmer, or you can try putting your SUIT TEMP valve to HIGH, if you haven't already got it there.

Aquarius, something we're thinking about right now is, if we can do it without using a lot of RCS, it would be to our advantage timewise to try to get an alinement.

Okay. You mean a P52?

We're —

I'll … around.

A combination of 51 and 52.

I'll see what we can do, Jack.

Aquarius, Houston. On panel 16, we'd like for you to close the CROSS TIE BAL LOADS breaker, please.

Okay. It's closed.

And it looks like we could support a—an alinement in a few minutes, if you'd be willing to go ahead with that.

Jack, it sounds good. I think from our position here, we know where the Sun and Moon are and it's strictly going to be a pitch maneuver. But I think we can save some gas. I'll see what we can do.

Houston, Aquarius.

Go ahead, Aquarius.

We're all set to go. Are you going to ship us up a REFSMMAT?

Yes, we are. Stand by 1.

Okay.

The Sun feels wonderful. It's shining in the rendezvous window.

And, Aquarius, before we can ship you a load, we'll have to have, on panel 11, under COMM, the UPDATA LINK circuit breaker closed.

It's closed.

Roger. It'll be a few —

… closed … -

Okay. And it'll be a few minutes yet, Jim. We're still cranking it up.

Okay. Stay with it, Jack, and I'll go back to data.

Roger.

I got BAT in about 33-1/3 percent on that uplink. Too fast alarm.

Say again on that, Fred.

I just got another uplink too fast when I took the DATA switch back off—It's happening, I guess, about a third of the time.

Aquarius, Houston. We're ready with your load if you'll give us DATA please.

Aquarius, Houston. After the uplink, you'll have to set the drift and the REFSMMAT flag as on page 8 of the contingency book, steps 5 and 6.

Okay. Are you done with the computer now, Jack?

Negative. We'll give you the word.

Roger. Aquarius, we're through with it, it's your computer.

And, Aquarius, Houston; take option 1 on a P52 when you get to it. And I've got some ball angles for a Sun and Moon.

And have you got some plan in vectors for us, Jack?

Okay, Fred-o. For the Sun, I've got 246; for the Moon I've got 250.

Are you talking about ball theta angles?

Negative. I was—I was reporting the code for NOUN 70.

They're in the computer, Fred.

Okay, Houston. We have the Sun marks and I'll start up at pitch now to go over and pick up the Moon.

Houston, Aquarius.

Go ahead.

Just as a note of interest in this dock configurations for P52s, the command module docking probe is right down the middle of—the docking light, rather, is right down the middle of the detent. And when the Sun flashes on, it really makes it difficult.

Just like the simulator.

Yes. It was good training.

Well, Jack, that's what it says the torquing angles are.

We haven't got them yet.

Aquarius, hold on to torquing angles, please.

We're doing that.

Jim, the reason for the delay is that we're not seeing the data yet. We're having to check a point here; and as soon as they come up, we'll let you know what to do with them.

Okay. We had a large NOUN 105 of—what—112, and our torquing angles, Jack, are minus 01713, minus 03278, minus 01395.

Roger. Minus 01713, and we see them now.

Aquarius, torque them.

Okay.
