Spacelog Apollo 13

Okay, Aquarius. On my mark, it's going to be 34 minutes to the burn, and you'll be reading 36. Stand by.

MARK.

Okay, Houston. We have our attitude set.

Roger, Jim.

I hope the guys in the back room who thought this up right knew what they were saying.

And I'm looking through the AOT there, Jack, and the Sun's right in the top and it's about maybe 2 degrees to the right of the cursor. So that looks real good.

Roger. Good going.

Okay, Aquarius. The attitude looks good here and your choice when you want to start the burn.

We're counting down, aren't we, or do you want us to start any time?

Your choice.

You guys are getting easy.

It's not time critical, Jim.

And, Houston, we reset our clock and we're making the burn in about—I'll give you a hack here at 2 minutes to go.

Roger, Fred. And let us know when you're going to ullage, will you?

Okay.

Okay. Stand by. 2, 1.

MARK it.

Three minutes to go. Correction, 2 minutes to go, Jack.

Roger. Two minutes. We got it.

Aquarius, Houston. Check engine gimbal off, please.

It's verified to off. And -

MARK it.

One minute.

Roger, Fred.

Roger. We concur with that. And it looks like you got a little pitch rate going on here. Do you copy the same?

Okay. My pitch needle is just slightly up now. I could try to take it out if you want me to.

Not—Wait, wait. There you go.

Just hold off on it 1, Jim. We'd like to take a look at it.

Okay.

Aquarius, we'll need high bit rate, please.

Flashlight, Jack. Jack, flashlight over here a minute.

Aquarius, we need the POWER AMPLIFIER back in high bit rate, please.

You got it.

You got a couple in the roll pretty soon.

What is it, 1.7?

You have another set of them by the PGNS.

Now we got to turn on the heaters you want to save -

What's that flitting out there in the breeze? Are we venting again? Take a look, Jack.

Well, once we get squared away, Joe, I think I am going to have to go to the space center and take a good healthy one and leave just about everything. I've held up long enough.

That's coming from above. Another one just—is just coming down right over here. Well, there's the old terminator at Fra Mauro. We'd been landing about 2 hours ago, huh? Right on the —

Houston, Aquarius.

— to the right of the terminator.

Go ahead, Aquarius.

Just for information, although I thought I'd never have to use it, that technique looked like it was a pretty good one.

Roger, Jim. And we'd like you to give us your idea of how the PTC looks. We're not sure we're seeing what we ought to here.

Okay. I still have my ball powered up and I'm coming around past 270 right now. I've got a slight roll and pitch offset in there. My pitch needle about halfway up and my roll needle is about 4 degrees over now.

Okay, Jim. With that info we'll go on the PTC, and let's proceed with the powerdown.

Okay. We'll proceed with the PTC and proceed with the powerdown. I guess if we have to we can reestablish PTC at a later date. Okay. Okay.

First row. Ullage. AGS.

Your AGS on?

My what? My what? Oh, yes. Go ahead.

Okay. The four INVERTERS of this AC BUS volt, Fred.

Okay. Go ahead.

Okay. Let's—give the last thing to Jack and I'll keep it all out. Okay? RCS SYSTEM A. That's in. TCAs are going off. Why do they need the ISOL valves in the ASCENT FEED in?

You're not sucking any power unless you take these switches and move them.

How come we pulled them out, then, in this burn?

Because you didn't want them to get moved inadvertently, I guess. It doesn't matter, Jim, they can be out or in in terms of powerdown. They just don't count.

Okay. I got 1, 2, 3.

ISOL valve should be in 2.

Yes. Okay. Third row. Attitude DIRECT CONTROL I still have in.

Jack, how do you read now in baseband?

Reading you 5-square, Fred. How me?
