Spacelog Apollo 13

Okay. If I understand you correctly, then that gives me leeway to maneuver when we get up to activation complete, and we can be in position for the burn, but we will not burn. We don't have a pad anyway.

That's affirm, Jim. You could maneuver to burn attitude, or you could maneuver to an attitude which should put the Sun in the windows to warm the place up.

Sounds good, and you're sure we have plenty of electrical power to do this?

That's affirmative. We've got plenty of power to do it. I can get you a number, though.

Jim, you've got about 100-percent margins on everything from here on in.

That sounds encouraging.

Roger. That's in the LM. We're not talking about the CSM right now.

Houston, Aquarius.

Go ahead, Aquarius.

Okay. Question. This short turnon step 3 on page 24 has us only turning on the RCS SYSTEM A/B, two quads, and the breakers are still out on panel 11. Did you want those in, too, or are we just going to use one set of heaters?

Stand by.

Aquarius, Houston. Go as the checklist recommends for now. When you get into the circuit breaker panel configuration, you're going to get the number 1 set of heaters on anyway.

Okay, Houston. We'd like to get a hack to set our mission timer here, Jack.

Okay, Fred-o. Set it at 133:35 straight up. You've got about 30 seconds to set it.

Okay. Standing by.

Okay. I'll give you the 2-second delay in there. Stand by to start.

START.

Okay. We've got it.

Okay. I'm counting 133:35:10.

Right on.

Aquarius, Houston. One other way to warm things up in a hurry in there is when you get your AC on to turn on the window heaters.

Okay. I guess the only question I have is what it's liable to do to us with the—looks like almost a frost on it now.

Understand this, Jack. I'd like to let it maybe warm up just a little bit more before hitting it with the heat load.

Not a bad idea.

And, as you can see, Houston, at turnon we got our old friend downlink 2 back.

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.

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.
