Spacelog Apollo 13

Roger, Jim. Ready to look at it with you.

Twelve clicks right.

Okay, Jack. Are we clear now to proceed with the powerdown?

That's affirmative, Fred. We're ready to press on with powerdown. I've got two changes for you. Step 1 of the emergency powerdown on page power—5. Over.

Go ahead.

Okay. Leave your POWER AMPLIFIER switch in PRIMARY vice OFF and put your RANGING switch to RANGE, vice OFF/RESET.

Okay. We're in PRIM in the POWER AMP and RANGING on RANGING.

Affirmative.

Okay. I'm going to pull. Well, here, let's just look at the checklist.

Okay. Configure CBs. There you go.

Aquarius, Houston, hold off 1 on powerdown, please.

Okay. We'll hold off. And we're looking at a SHe pressure, incidentally, of about 1830 now.

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, 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?
