Spacelog Apollo 13

Okay. Joe. As I read that, at 74 hours we're going to do an AOT Sun check at detent 2, which is going to require the rendezvous radar out of the way. And we use P52 AUTO maneuver to get there, or at least the angles out of that, and if this passes within 1 degree, you're saying the platform is okay for the maneuver, and we won't need a subsequent P52. But even if it is okay, you'll give us a star which we can use for our check when we're in darkness. If this check flunks, you'll pass us on up then an Earth/Moon aline procedure.

Okay, Fred. That's correct, except the aline procedure that we're working on is an Earth/Sun aline, and other than that, that's correct. Incidentally, this TC plus 2 maneuver looks like it will still be around a 900-foot-per-second maneuver and that it will get you back to the mid-Pacific line at 142 hours.

Okay. That was an Earth/Sun check, John. We're getting a little close to the Moon now. And the TC plus 2 maneuver still looks about 900 foot per second to get us at mid-PAC, at about 142 hours.

Aquarius, Houston.

Go ahead, Joe.

Okay, Fred. We got a good batch of ranging and now we'd like you to reverse the configuration, RANGING to OFF, VOICE FUNCTION to DOWN VOICE BACKUP, POWER AMPLIFIER circuit breaker out; we'll be talking to you.

DOWN VOICE BACKUP with the POWER AMP breaker open now. How do you read?

We read you satisfactorily, Fred.

Okay.

And, Houston, Aquarius.

Aquarius, Houston. Go ahead.

One other thing you might have somebody look at—I don't want to bother the guys upstairs—the drain hose that we've got in the command module, I wonder if we can find out if it will plug into the PLSS and in which case we can keep transferring—later on at least—the command module water into the LM via the PLSS.

Okay, Fred. You're almost up with us. We are looking real hard at getting water from the command module waste tank into the PLSS, using that hose and then dumping it from the PLSS into the LM ascent tank, and we think it is feasible; we're checking it out to make sure.

Okay.

Okay. I have time to do another maneuver here, Joe.

Okay, Fred. Let me verify that.

Fred, Houston. That is verified. You can go ahead with the yaw maneuver.

Okay. Just made another maneuver. We allowed for a little too much roll, there. I wonder if that's too much, or should I try to take it out now that I got it stopped.

Fred, this is Houston. —

Twenty degrees roll left—Yes. All right; go ahead.

Okay, Fred. I didn't copy the beginning of your message.

Okay, I—I was talking to Jim, there.

Aquarius, Houston. Over.

Go ahead, Joe.

Roger. Listen, Charlie Duke wants to talk to you—to you about the AOT star check; and, so that we can have good COMM, I'd like to reconfigure with the POWER AMPLIFIER circuit breaker in and the VOICE FUNCTION switch to VOICE and while we're at it, we'd like the RANGING FUNCTION switch to RANGING. Over.

Okay.

Aquarius, Houston. Over.

Houston, Aquarius.

Roger, Fred-o. Reading you —

Okay, Houston, Aquarius. Go ahead.

Okay, Fred-o. Reading you 5-by. The procedure I'm going to read up to you is a Sun check for the—to see if we're going to need an alinement or not. If you'll get out your G&N dictionary and open it to P52, page 34, we'll start at the bottom. Over.

Okay. Stand by 1.

Sounds like you broke out, Charlie.

Yes, finally, Fred-o. I've no longer got the red spots.

Okay. Stand by, Aquarius. We'll be back with you momentarily.

Okay.

Aquarius, Houston. You ready with your G&N dictionary? Over.

Okay. I'm on page 34 now, looking at P52.

Okay, Fred-o. At the bottom of the page, we want step 1, on the flashing 0406, we want an option 3, and that'll pull us over to 6; and, on the 5025, we want you to do the ENTER on the 5025, and that'll bring up flashing 0170, and load in R₁ 200. Over.

Okay. Let me see if I'm with you. We call up P52 and, on the flashing 0406, we PRO on a 3 REFSMMAT which leads us to a flashing 5025. We ENTER on that. On the flashing 0170, we want to ENTER a 200.

That's affirmative; and after that, you PRO on that, and you come up with a flashing 0688, and we'll have to load NOUN 88. And if you're ready to copy, I have the Sun half-unit vectors at 74 hours GET. Over.

Okay. Go ahead.

Okay. At Sun half-unit vectors, X, R₁, is plus 0.45498, Y plus 19024, Z plus 08250. Over.
