Spacelog Apollo 13

Aquarius, Houston, I have some additional entry data that goes with the pad I just read up. It's five items. Let me know when you're ready to copy. It's on a maneuver pad.

Okay. I'll try to squeeze them in there, Jack. I'm rapidly running out of pads.

Go ahead.

Okay. It's N/A all the way down to NOUN 61. Your latitude is minus 21 —

Hold on a minute; hold on. You need the—Hold on, Jack, I need the other pad book, that CSM pad.

That's affirm.

Okay. Now I'm ready.

Okay. NOUN 61: latitude, minus 21.67, minus 165.37, 1163.1, 36292, 142:41.02. Read back.

Okay. NOUN 61; minus 21.67, minus 165.37. 1163.1, 36292, 142:41.02.

Good readback.

And you should have high bit rate now, Jack.

Houston, Aquarius.

Go ahead, Aquarius.

Did you have readouts on our quad temps to know when we can start? We're taking a time hack. We'd just like a verification with you.

Okay, Houston; Aquarius. We're going to stop PTC at this time.

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.

ENGINE ARM to DESCENT.

ULLAGE.

Okay. You're looking at 470.

Roger. We copy 7.4.

Roger. 7.4 and I had about 0.2 showing, I guess, when we started.

Roger. We verify that, Okay, Aquarius. Trim it to 7.6.

Okay. You want plus-X now to get 7.6. Is that correct?

That's affirmative.

Okay. You're looking at it, Houston.

Okay. Looks good. Nice work.

Let's hope it was.

Okay, Aquarius. We're ready to follow you through on setting up PTC and powerdown. Your choice.

Aquarius, Houston. We'd like to change the number of yaw pulses we gave you before as 21. We'd like to reduce that to 12. Twelve pulses yaw right, and that'll take you about 3 seconds to get them in if you don't want to count them.

Okay, Houston. I'm just about there now and as soon as I get 90, we'll start damping rates.

Okay, Houston. I'm trying to damp rates now. We're at the proper roll attitude and pitch.

Roger, Aquarius.

Working a little bit better this time.

Are you copying any attitudes down there, rates, et cetera?

Okay, Aquarius. We're seeing some extremely low rates at this time, really below our capability to measure them.

Roger.

Houston, I think I've got pitch and roll just about squared away. I let yaw just slightly drift; it's drifting in a clockwise direction and I'm about all set now to put in my 12 clicks to the right.
