Spacelog Apollo 13

How you doing, Jack?

Do you have an hour on your clock for …

Joe, this is Aquarius; wonder if you can give me the GET time of initial powerup?

Fred, Houston. Understand you'd like to know the GET of your initial powerup, is that correct?

Yes, the second time in here.

Okay, stand by.

Aquarius, Houston. Over.

Go ahead.

Okay, we don't have a percise time for the starting of that procedure yet; we are working on it real hard. It won't be for several hours; and we'll pass it up to you just as soon as we get it. Over.

Okay, and, Joe, you want us to start a PTC maneuver at this time?

Stand by and I'll check.

Aquarius, Houston.

Go ahead.

Roger, Jim. We would like the next yaw maneuver in about 6 minutes. Over.

Roger.

Okay.

Oh, yes, yes. Keep opening—open the jets slowly … Keep working at it.

Is there some way that we could … water in the PLSS.

Aquarius, Houston. Over.

Go ahead.

Okay. Our estimate is that we will start powering up for the DPS burn at about 76 hours elapsed, which is about 6-3/4 hours from now.

Roger, Joe. Understand.

Okay, Joe, about 76 hours or so and I guess you misunderstood. My question was what was the GET way back when, when I first came across to the LM and transferred to LM power? How long have we been living on the LM, now?

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, the time of transfer to LM power was 57 hours, 11 minutes. For your information, we seem to be reasonably fat on power. In fact, we are looking at a procedure that we might recommend to you later on after the burn and so forth of powering up one of the command module main buses via the LM umbilical. This would enable us possibly to charge up the command module batteries. Over.

Okay, Joe. That sounds great. I just thought that to pass the time, I'd do a little backseat quarterbacking, here.

I'm trying to … this heater over here.

Yes. I'll … that.

Jim, that spacecraft's looking pretty close; a about 86 or …

Well, …

Aquarius, Houston. Over.

Go ahead, Houston.

Okay, Fred. I have a few words for you on some things we want to do in the next few hours, and in order to get good COMM for that and also in order to give FIDO a few minutes of ranging, I want to have you put the POWER AMPLIFIER circuit breaker in panel 16 in, the VOICE FUNCTION switch to VOICE, and RANGING FUNCTION switch to RANGING. Over.

Now I'm in NORMAL voice and RANGING is up.

Okay, Fred. And you're loud and clear down here now. Okay. What we're getting a procedure ready for you is to do an AOT Sun check at approximately 74 hours or in just a little over 3 hours. That will be a detent 2; we'll have a detail procedure up shortly and it will include a rendezvous radar redesignation to get it out of the way and a P52 maneuver to the attitude. It's our feeling that if that checks out within 1 degree that your platform will be okay for the burn without a subsequent P52. If it's not within 1 degree, we are working up an Earth/Sun alinement procedure to aline the platform, and we'll have that up to you later. Okay. Assuming that the Sun check is okay, we will then give you a star for a confidence check on the back side when you're in the darkness. We'll be updating a burn pad to you prior to LOS going around the Moon. We'll have another look at you after AOS, and we'll update the pad if required. Right now that update should be very small. Over.

Okay. Stand by 1.
