Roger, we understand that. It is strictly a downlink problem and you can stay in the DOWN VOICE BACKUP mode if you want. If we get involved in conversation, I think we'll want to go back to NORMAL voice.

Fred Haise (LMP)

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?
-
Joe Kerwin (CAPCOM)
-
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.
-
Joe Kerwin (CAPCOM)
-
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.
-
Fred Haise (LMP)
-
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?
-
Joe Kerwin (CAPCOM)
-
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.
-
Fred Haise (LMP)
-
Okay, Joe. That sounds great. I just thought that to pass the time, I'd do a little backseat quarterbacking, here.
-
Joe Kerwin (CAPCOM)
-
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.
-
Joe Kerwin (CAPCOM)
-
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.
-
Fred Haise (LMP)
-
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.
-
Joe Kerwin (CAPCOM)
-
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.
-
Fred Haise (LMP)
-
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.

Joe Kerwin (CAPCOM)

Aquarius, Houston.

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.
-
Fred Haise (LMP)
-
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.
-
Joe Kerwin (CAPCOM)
-
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.
-
Fred Haise (LMP)
-
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.
-
Joe Kerwin (CAPCOM)
-
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.
-
Charlie Duke
-
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.
-
Charlie Duke
-
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.
-
Fred Haise (LMP)
-
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.
-
Charlie Duke
-
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.
-
Charlie Duke
-
Okay. At Sun half-unit vectors, X, R1, is plus 0.45498, Y plus 19024, Z plus 08250. Over.
