Spacelog Apollo 13

Aquarius, Houston.

Go ahead.

Okay. Here's the big story. Your attitude really looks quite good except in roll, and we'd like you to do the following. In MIN impulse PGNS, we'd like you to trim to zero pitch, which is about where you are now; to 008 degrees in roll, which is about 16 degrees from your present roll attitude; and to zero degrees in yaw, which is about where you are now. Then we'd like you to do the body-axis aline 400 plus 5, 400 plus 0. PITCH and ROLL to PULSE, select AGS, do the burn in AGS. How does that sound? Over.

Okay. I'm rolled the wrong way; that is what you're saying, right?

That's right.

And you know I can't roll in minimum impulse. I've got to use TTCAs.

That's right, Jim. Sorry.

And you don't want me to automatically trim 5018, I take it.

That's affirm, Jim. Don't trim 5018.

Okay.

We just want you to cycle on through P41 to get the average g and burn it out.

Okay.

Aquarius, Houston.

Go ahead.

Just for your information, we see 3.0 in register 1. We read you up 3.1 on the pad. The actual DELTA-V was 3.05, and they warned me that it might come out 3.0.

Okay. That's a little burn.

Right.

Aquarius, Houston. Your attitude looks real good. We will give you a mark at 10 minutes to the burn, which is in 28 seconds.

Okay. We'll burn it in AGS and use the AGS ball.

Right. I was looking at the wrong clock, and we're a little under 10 minutes now. I'll give you a mark at 9 minutes. Okay?

That's fine.

Aquarius, Houston. We have 10 seconds until 9 minutes to the burn. 3, 2, 1 -

MARK.

Nine minutes.

Very well. That agrees with our event timer.

Okay, Houston. About 3 minutes to go, and we're all squared away.

And, Aquarius; Houston. Roger that. And we're standing by for your body-axis aline and your zeroing 404, 405, 406, going to 470.

Okay. You'd asked—you'd asked me before, Joe, to go 400 plus 3, which I did. I assume you've changed the script again.

Okay, Fred. We did tell you to do that awhile ago, and it doesn't matter; you're looking good.

Okay.

Roger. Aquarius, Houston. You're good right where you are.

Okay. That's it.

Okay. If you're happy, can we maneuver to service module SEP attitude now?

That's affirmative, Aquarius.

And I'm pitching up to the proper attitude.

Okay. We're looking at it.

And it's again necessary to use the TTCA to pitch.

Aquarius, Houston.

Go ahead, Houston.

Okay. Recommend you terminate P41.

Hey, Jim, have you broken into the medical kit per my recommendation a few hours ago?

Yes. Everything is taken care of Deke.

Okay, fine. You might hit it again in about 2 hours.
