Spacelog Apollo 13

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.

At 35:04:25.

Aquarius, do you have a star close by there you could check?

I'll look around, Jack. I was just trying to get a check on the Moon, again, to see if those angles were indeed true, and we got the Moon back again and centered.

Okay, Jack. What you're reading now the angles? We had the Moon centered, and it's pretty close to what we have on the 8 ball, I guess. Close enough for any entry that we'd like to do.

Roger. And I'm told that Denubla—Denebola and Regulus are nearby if you wanted to make a star check.

Okay. I'm going to start pitching around again, and I'll see if I can pick them up. I have Orion out here to my left a little bit, but it's pretty close to the—oh, here. I've got Sirius. That's a nice one. How about that?

Aquarius, is Jack sitting on the rumble seat there?

He was. He just headed upstairs to take another look around.

Okay. I got a minor addition to the entry checklist for him. This time it's in the —

Okay. Stand —

— entry book.

Okay. Stand by 1. He has that in his pocket.

What I'm doing, Jack, is just—I'm pitching over now. I'm going to pick up another star. Sirius was just too far off. I thought I was going to use too much gas getting there.

Roger.

By the time I get alined in the—in the AOT—be nice if we didn't have Odyssey attached, we could just AUTO—AUTO maneuver over to these things.

Looks to us like you've got her alined, Jim, so I wouldn't worry about it too much.

Yes. I'm pretty confident that the platform's fairly decent.

Aquarius, Houston. We need an E MOD VERB 74, when you've got a chance, please.

Okay, Jack. On your entry checklist, on page 2-5. Down there on step 9, where it says 152 degrees pitch at .05g, adjacent to that, so that Recovery can see you better on the way down, we want you to turn your S-BAND, POWER AMPLIFIER to HIGH. Over.

Okay. Turn S-BAND, POWER AMP to HIGH at .05g time.

That's affirmative.

Okay. Is that it?

Aquarius, Houston. We're considering doing the midcourse with PGNS, unless you'd rather do it in AGS.

No. PGNS is fine with me. I just aline myself up with the old ball again. So I've got you foresighted again, but any way you want to do it.

Like you say, you might as well go first class.

I guess you're right.

Now wait a minute, Jack.

I just lost a lot of friends there.

And, Jack, you can tell Owen Morris that the RCS SYSTEM A/B 2 QUAD 1 breaker is still nicely in.

Aquarius, Houston. We think we've figured out a way to save you some time at a very critical—very full schedule. And that's by doing a docked coarse aline, since we got the LM up now. That would save you a maneuver or two.

Houston, Aquarius. It seemed to me a docked coarse aline might be quicker for—for Jack.

Yes. We think it would be, and it'd save quite a bit of time at a place where you're going to be pretty busy. Also save you some petrol.

Affirm.

Okay, Jim. We're looking at doing this in the service module SEP attitude, and the optics will be pointed away from the Sun. So it should be a good attitude for a P52.

Okay. So, we'll be going to the service module SEP attitude, at which time we'll do a docked coarse aline, and -

Then you want—You want Jack then to do a P527

The way we'll do that in our time line Jim, is to go ahead and do the service module JETT and then we'll just stay in that attitude and when it comes time in our time line as we've outlined, to bring the platform up, we'll proceed with the P52—coarse aline, and then the P52.

Okay. Are we going to use the same techniques that we normally do for LM activation? In other words, I try to maintain an attitude, and give him some angles and then—Are you going to give him the angles? Then he does the 52.

Basically, it's the same procedure just reversed, Jim.

Okay.

Another nice thing about this, is it's one we've done before.

And, Aquarius. One thing, however, that we do not plan to do is to proceed with the command module powerup prematurely.

Roger.

Okay, Houston. This is Jack.
