Jim Lovell (CDR)
-
Okay. If I understand you correctly, then that gives me leeway to maneuver when we get up to activation complete, and we can be in position for the burn, but we will not burn. We don't have a pad anyway.
-
Jack Lousma (CAPCOM)
-
That's affirm, Jim. You could maneuver to burn attitude, or you could maneuver to an attitude which should put the Sun in the windows to warm the place up.
-
Jack Lousma (CAPCOM)
-
That's affirmative. We've got plenty of power to do it. I can get you a number, though.

Fred Haise (LMP)

Okay. Question. This short turnon step 3 on page 24 has us only turning on the RCS SYSTEM A/B, two quads, and the breakers are still out on panel 11. Did you want those in, too, or are we just going to use one set of heaters?
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. Go as the checklist recommends for now. When you get into the circuit breaker panel configuration, you're going to get the number 1 set of heaters on anyway.
-
Jack Lousma (CAPCOM)
-
Okay, Fred-o. Set it at 133:35 straight up. You've got about 30 seconds to set it.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. One other way to warm things up in a hurry in there is when you get your AC on to turn on the window heaters.
-
Fred Haise (LMP)
-
Okay. I guess the only question I have is what it's liable to do to us with the—looks like almost a frost on it now.
-
Fred Haise (LMP)
-
Understand this, Jack. I'd like to let it maybe warm up just a little bit more before hitting it with the heat load.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. It looks like you're proceeding toward the gimbal lock there. We'd like you to check that, please.
-
Fred Haise (LMP)
-
And, Houston, Aquarius. I guess the next thing for the PGNS will be a coarse aline 000, but I guess we ought to hold up now until we get enough time on the RCS thrusters.
-
Jack Lousma (CAPCOM)
-
Roger. We're looking at them. We'll give you the GO on them. Okay, Aquarius. Your quads are 120 to 133 now, so you're cleared for—Cleared for thrusters.
-
Jim Lovell (CDR)
-
That's affirm. We're GO. What we're doing now, Jack, is letting the spacecraft drift in this mode to pick up the Earth again.
-
Jim Lovell (CDR)
-
I don't want to just go blasting around the sky and get high rates, because I don't have anything to null the rates on until the Earth comes back up again. And—Once I get the Earth in sight, we have no strain on nulling rates. That part of the Earth, that is.
-
Jim Lovell (CDR)
-
It's going to be interesting today, Jack. The Earth's a lot bigger; the crescent is a lot more pronounced than it was yesterday.
-
Fred Haise (LMP)
-
And, Jack, I guess we haven't changed our angle much with respect to the Sun 93 million miles away, so it ought to be in about the same place in the AOT, isn't that Charlie?
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. When you look out a detent 2 in the proper burn attitude, what you ought to see is the Sun at 12 o'clock, about halfway between the top of the AOT and the center of the pipper. And you ought to see the Earth —
-
Jim Lovell (CDR)
-
Jack, I've gotten so used to flying attitude with the TTCA, I won't be able to do it normally.
-
Jim Lovell (CDR)
-
I said I've gotten so used to flying attitude with the translational control, I won't be able to do with the ACA.
-
Jack Lousma (CAPCOM)
-
Aquarius, we see your glycol temperature getting up there. If you want to make it a little warmer, or you can try putting your SUIT TEMP valve to HIGH, if you haven't already got it there.
-
Jack Lousma (CAPCOM)
-
Aquarius, something we're thinking about right now is, if we can do it without using a lot of RCS, it would be to our advantage timewise to try to get an alinement.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. On panel 16, we'd like for you to close the CROSS TIE BAL LOADS breaker, please.
-
Jack Lousma (CAPCOM)
-
And it looks like we could support a—an alinement in a few minutes, if you'd be willing to go ahead with that.
-
Jim Lovell (CDR)
-
Jack, it sounds good. I think from our position here, we know where the Sun and Moon are and it's strictly going to be a pitch maneuver. But I think we can save some gas. I'll see what we can do.
-
Jack Lousma (CAPCOM)
-
And, Aquarius, before we can ship you a load, we'll have to have, on panel 11, under COMM, the UPDATA LINK circuit breaker closed.
-
Fred Haise (LMP)
-
I just got another uplink too fast when I took the DATA switch back off—It's happening, I guess, about a third of the time.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. After the uplink, you'll have to set the drift and the REFSMMAT flag as on page 8 of the contingency book, steps 5 and 6.
-
Jack Lousma (CAPCOM)
-
And, Aquarius, Houston; take option 1 on a P52 when you get to it. And I've got some ball angles for a Sun and Moon.
-
Fred Haise (LMP)
-
Okay. We want an option 1 and you've got some ball angles for Sun and Moon. And right now, Jim has the Sun pretty well squared away right in the middle of AOT.
-
Jim Lovell (CDR)
-
Okay, Houston. We have the Sun marks and I'll start up at pitch now to go over and pick up the Moon.
-
Jim Lovell (CDR)
-
Just as a note of interest in this dock configurations for P52s, the command module docking probe is right down the middle of—the docking light, rather, is right down the middle of the detent. And when the Sun flashes on, it really makes it difficult.
-
Jack Lousma (CAPCOM)
-
Jim, the reason for the delay is that we're not seeing the data yet. We're having to check a point here; and as soon as they come up, we'll let you know what to do with them.
-
Jim Lovell (CDR)
-
Okay. We had a large NOUN 105 of—what—112, and our torquing angles, Jack, are minus 01713, minus 03278, minus 01395.
-
Jim Lovell (CDR)
-
I'll look around, Jack. I was just trying to get a check on the Moon, again, to see if those angles were indeed true, and we got the Moon back again and centered.
-
Jim Lovell (CDR)
-
Okay, Jack. What you're reading now the angles? We had the Moon centered, and it's pretty close to what we have on the 8 ball, I guess. Close enough for any entry that we'd like to do.
-
Jack Lousma (CAPCOM)
-
Roger. And I'm told that Denubla—Denebola and Regulus are nearby if you wanted to make a star check.
-
Jim Lovell (CDR)
-
Okay. I'm going to start pitching around again, and I'll see if I can pick them up. I have Orion out here to my left a little bit, but it's pretty close to the—oh, here. I've got Sirius. That's a nice one. How about that?
-
Jack Lousma (CAPCOM)
-
Okay. I got a minor addition to the entry checklist for him. This time it's in the —
-
Jim Lovell (CDR)
-
What I'm doing, Jack, is just—I'm pitching over now. I'm going to pick up another star. Sirius was just too far off. I thought I was going to use too much gas getting there.
-
Jim Lovell (CDR)
-
By the time I get alined in the—in the AOT—be nice if we didn't have Odyssey attached, we could just AUTO—AUTO maneuver over to these things.
-
Jack Lousma (CAPCOM)
-
Looks to us like you've got her alined, Jim, so I wouldn't worry about it too much.
-
Jack Lousma (CAPCOM)
-
Okay, Jack. On your entry checklist, on page 2-5. Down there on step 9, where it says 152 degrees pitch at .05g, adjacent to that, so that Recovery can see you better on the way down, we want you to turn your S-BAND, POWER AMPLIFIER to HIGH. Over.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. We're considering doing the midcourse with PGNS, unless you'd rather do it in AGS.
-
Jim Lovell (CDR)
-
No. PGNS is fine with me. I just aline myself up with the old ball again. So I've got you foresighted again, but any way you want to do it.
-
Fred Haise (LMP)
-
And, Jack, you can tell Owen Morris that the RCS SYSTEM A/B 2 QUAD 1 breaker is still nicely in.
-
Jack Lousma (CAPCOM)
-
Aquarius, Houston. We think we've figured out a way to save you some time at a very critical—very full schedule. And that's by doing a docked coarse aline, since we got the LM up now. That would save you a maneuver or two.
-
Jim Lovell (CDR)
-
Houston, Aquarius. It seemed to me a docked coarse aline might be quicker for—for Jack.
-
Jack Lousma (CAPCOM)
-
Yes. We think it would be, and it'd save quite a bit of time at a place where you're going to be pretty busy. Also save you some petrol.
-
Jack Lousma (CAPCOM)
-
Okay, Jim. We're looking at doing this in the service module SEP attitude, and the optics will be pointed away from the Sun. So it should be a good attitude for a P52.
-
Jim Lovell (CDR)
-
Okay. So, we'll be going to the service module SEP attitude, at which time we'll do a docked coarse aline, and -
-
Jack Lousma (CAPCOM)
-
The way we'll do that in our time line Jim, is to go ahead and do the service module JETT and then we'll just stay in that attitude and when it comes time in our time line as we've outlined, to bring the platform up, we'll proceed with the P52—coarse aline, and then the P52.
-
Jim Lovell (CDR)
-
Okay. Are we going to use the same techniques that we normally do for LM activation? In other words, I try to maintain an attitude, and give him some angles and then—Are you going to give him the angles? Then he does the 52.
-
Jack Lousma (CAPCOM)
-
And, Aquarius. One thing, however, that we do not plan to do is to proceed with the command module powerup prematurely.
-
Jack Swigert (CMP)
-
Okay. I just wanted to talk over with you, it looks like we've had some changes in the flight plan here, due to Jim's P52. Do you have—Can you talk over with me what your plans are?
-
Jack Lousma (CAPCOM)
-
Roger, Jack. Since we've got the PGNS up, we plan to use that information to give the CMC a dock coarse aline, and then we're in the service module jettison attitude, we'll wait until it comes time to power up the CMC, and we'll get the CMC a dock coarse aline, and we'll pick some good stars to give you a fine aline with, and it looks like we can pick some stars that are looking away from the Sun in which you can find in that service module jettison attitude; so, we'll save you quite a bit of gas: and save you some time in a very busy time.
-
Jim Lovell (CDR)
-
I'm looking out the window now, Jack, and that Earth is whistling in like a high-speed freight train.
-
Jim Lovell (CDR)
-
I don't think there's many LMs that have seen it like this. I'm still looking for Fra Mauro and Cone Crater.
-
Jack Swigert (CMP)
-
Okay, Jack. It looks—just looking over what I may expect here, it looks like I'm just going to get three angles to do a VERB 41 NOUN 20, right?
-
Jack Lousma (CAPCOM)
-
That's what it looks like from here, Jack. It's pretty much the opposite of the LM activation procedure where we do the dock coarse aline.
-
Jack Swigert (CMP)
-
Yes, except in a way we did a lot of VERB 06 NOUN 20, ENTERS, simultaneously, and then you all shipped him up post-torque values. You're not going to do anything like that are you?
-
Jack Lousma (CAPCOM)
-
Okay. During the activation part, we do a lot of VERB 06 NOUN 20, ENTERS simultaneously, reading you out the difference in the angles, and then MSFN furnishes the post-torquing angles, in order to get the platform fine alined. Do you plan something like that or just three coarse aline angles.
-
Jack Lousma (CAPCOM)
-
Jack, we're going to give you three coarse aline angles, and then you can go right to your checklist as we're giving it, and start in with the VERB 40 NOUN 20.
-
Fred Haise (LMP)
-
I was around shooting pictures of all the debris inside here, before we left, and I inadvertently changed the settings on the DC command module Reseau camera that we need for the service module pictures. I wonder if FAO can dig them out again—what we need, f-stop and speed.
-
Jack Lousma (CAPCOM)
-
Fred, in regards to the camera settings, for black-and-white 3400 film, the settings were f:5.6 at 1/250th. Over.
-
Fred Haise (LMP)
-
Okay. I'd guessed right after all, but thank you.
