Spacelog Apollo 13

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?

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.

Go ahead, Jack.

Okay. I just wanted to talk over with you, it looks like we've had some changes in the flight plan here, due to Jim's P52. Do you have—Can you talk over with me what your plans are?

Roger, Jack. Since we've got the PGNS up, we plan to use that information to give the CMC a dock coarse aline, and then we're in the service module jettison attitude, we'll wait until it comes time to power up the CMC, and we'll get the CMC a dock coarse aline, and we'll pick some good stars to give you a fine aline with, and it looks like we can pick some stars that are looking away from the Sun in which you can find in that service module jettison attitude; so, we'll save you quite a bit of gas: and save you some time in a very busy time.

Hey, that sounds good. Really fine.

Keeping warm?

Hey, it's warmed up here now. It's almost comfortable.

I'm looking out the window now, Jack, and that Earth is whistling in like a high-speed freight train.

We're clocking you at 48 000 miles and coming in at about 9000.

I don't think there's many LMs that have seen it like this. I'm still looking for Fra Mauro and Cone Crater.

You're going the wrong way, son.

Okay, Jack. It looks—just looking over what I may expect here, it looks like I'm just going to get three angles to do a VERB 41 NOUN 20, right?

That's what it looks like from here, Jack. It's pretty much the opposite of the LM activation procedure where we do the dock coarse aline.

Yes, except in a way we did a lot of VERB 06 NOUN 20, ENTERS, simultaneously, and then you all shipped him up post-torque values. You're not going to do anything like that are you?

Say again, please, Jack.

Okay. During the activation part, we do a lot of VERB 06 NOUN 20, ENTERS simultaneously, reading you out the difference in the angles, and then MSFN furnishes the post-torquing angles, in order to get the platform fine alined. Do you plan something like that or just three coarse aline angles.

Jack, we're going to give you three coarse aline angles, and then you can go right to your checklist as we're giving it, and start in with the VERB 40 NOUN 20.

And, Jack, how do you read?

Fine—square.

I was around shooting pictures of all the debris inside here, before we left, and I inadvertently changed the settings on the DC command module Reseau camera that we need for the service module pictures. I wonder if FAO can dig them out again—what we need, f-stop and speed.

Okay, Fred. Stand by.

Fred, in regards to the camera settings, for black-and-white 3400 film, the settings were f:5.6 at 1/250th. Over.

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Jim. I got MCC-7 pad when you're ready to copy. Over.

Okay. Stand by.

Okay. We're in luck, I got one pad left.

Okay. We'll take care not to change this one. Ready to go?
