Fred Haise (LMP)

Okay. Vance, I guess I understood you all were amassing a couple of—list of things that you were thinking about later on—we'd be taking back from the LM across into the CSM. A couple of items to add to that list, we've pilfered the—the intake hose screens out of the CSM and we have them mounted on the LM hoses now to catch the debris in here. We probably ought to take those back.

Vance Brand (CAPCOM)

Okay. We got that. Intake hose screens.

Vance Brand (CAPCOM)

I guess that item isn't going to change your c.g. too much, Fred-o.

Jack Swigert (CMP)

… command module water.

Jack Swigert (CMP)

… Get out one of those big … bags.

Jim Lovell (CDR)

Much debris in there?

Jim Lovell (CDR)

Trying to put debris in?

Jack Swigert (CMP)

How's that for … (laughter).

Jack Swigert (CMP)

… didn't see any …

Fred Haise (LMP)

Yes. Oh, what I'd like to do is find out how many—Yes—What happened to the two little midcourses that's got to be with this vehicle.

Jim Lovell (CDR)

Now we just take the CSM and strip it down. Start putting the … stuff in here.

Jack Swigert (CMP)

Why are you worrying about that? Why are you worried about stripping down the vehicle?

Jim Lovell (CDR)

Well, you don't want—You don't want the drogue and the probe in.

Jim Lovell (CDR)

And, you do want room for the PLSSs. So, we'll grab this … suit valve and … them in there.

Jim Lovell (CDR)

Well, the suit … oxygen … the cabin.

Jim Lovell (CDR)

(Clears throat) We're not planning to reenter with suits.

Jim Lovell (CDR)

… a suit would help you out is for protection.

Jim Lovell (CDR)

They work on the REPRESS valve.

Jim Lovell (CDR)

Breathe through the canister.

Jim Lovell (CDR)

Yes, breathe through the canister.

Jack Swigert (CMP)

My job is to maintain …

Fred Haise (LMP)

You got all those things …?

Jack Swigert (CMP)

Yes, I think they forgot that.

Jim Lovell (CDR)

Sun must be coming back.

Jim Lovell (CDR)

Yes, I got two stars, circling back, Nunki and Antares … back up again.

Jack Swigert (CMP)

Actually, you can see …

Jack Swigert (CMP)

That's the one you put up there, … I would like to …

Jim Lovell (CDR)

Doesn't that also fit this big container back here?

Jack Swigert (CMP)

I wouldn't mind—… …

Jim Lovell (CDR)

Hey, can't you pilfer more there? Yes. …

Jack Swigert (CMP)

… what you do—what you do, you put your -

Jim Lovell (CDR)

Now, let's see, this burn's … to our back, I suppose. Let's hope it works.

Jim Lovell (CDR)

Now, let's see. What should we be doing here now?

Jim Lovell (CDR)

Okay. The next thing is power for the burn. Did they give you a time to start powerup?

Jack Swigert (CMP)

Yes, we ought to get a … You know, we ought to get … —

Jim Lovell (CDR)

Hello, Houston; Aquarius.

Jim Lovell (CDR)

Let's just recap the situation now. We're not going to do any more PTC. We'll maintain this attitude. You have already updated us on P30 load. We would like from you an LOS time, and a powerup start time for the PC plus 2. And an AOS time.

Vance Brand (CAPCOM)

We're going to also get back with you shortly, Jim, for—with some burn guidelines for PC plus 2.

Jim Lovell (CDR)

All right. Very well.

Jim Lovell (CDR)

Have they powered up the mission timer—the event timer?

Jim Lovell (CDR)

Oh, I see. Are they going to?

Vance Brand (CAPCOM)

Jim, we were just discussing burn star monitoring and we were curious to know if you can see Nunki in detent 2 at this time. Over.

Jim Lovell (CDR)

That's affirmative. I can see Nunki in detent 2.

Vance Brand (CAPCOM)

Okay. Thank you. Roughly, in what part of the field of view?

Jim Lovell (CDR)

Nunki is in the upper right-hand corner.

Jim Lovell (CDR)

And Scorp—And Antares is barely visible in the bottom of the field of view.

Jim Lovell (CDR)

Hey, I bet I know how I could get an alinement. Give them a cursor spiral angle. Instead of maneuvering the spacecraft, I'll give them cursor spiral.

Fred Haise (LMP)

Do that for AGS and …

Jim Lovell (CDR)

Houston, for what it's worth, we can probably give you a cursor spiral angle on Nunki and possibly Antares or more than likely Shaula.

Vance Brand (CAPCOM)

Roger, Jim. According to our calculations, Nunki should be, at burn time, pretty close to the center of the AOT. We've been talking that possibility over.

Vance Brand (CAPCOM)

Also, as a matter of general interest, the Sun should be in—at the bottom part of the CDR's window at the bottom of the LPD vertical line.

Fred Haise (LMP)

Be at Tig which is at —

Jim Lovell (CDR)

It must be that—You're right, because it's behind us now.

Jack Swigert (CMP)

Wait a minute, […] holding insertion attitude.

Fred Haise (LMP)

Yes, we're not at the Tig attitude.

Vance Brand (CAPCOM)

Jim, whenever you're through eating and ready to copy the info, I can send you the burn rules.

Jack Swigert (CMP)

Write them right on—…?

Jim Lovell (CDR)

Why don't you write them right in here?

Fred Haise (LMP)

Okay. I'll start on that.

Vance Brand (CAPCOM)

Okay. Okay. First of all, general philosophy is that these rules should be similar to LOI mode I abort with the tight limits. Now, I'll go through them one by one for you to copy. Okay. You should shut down, if any of the following happen. Thrust monitor readout, 77 percent or below; DPS propellant tank pressure—that's the inlet pressure—onboard readout, 160 or below; fuel to OX DELTA-P, greater than 25 psi—and that would have to be a ground call to you—attitude error plus or minus 10 degrees, with the exception of the start transient; attitude-rate limits, plus or minus 10 degrees a second. And you should shut down if you get any of the following alarms: ENGINE GIMBAL, ISS, plus PROGRAM ALARM, LGC, CES DC, and if you get an inverter light after switching inverters. Are you with me?

Vance Brand (CAPCOM)

And proceeding on. If, during the burn, the engine stops, if you have a flashing NOUN 97, you should PROCEED, then ullage, ENGINE START to PUSH, and DESCENT ENGINE OVERRIDE ON. Okay. Now just general information. If you didn't burn PC plus 2, probably P—P plus 4 would be the earliest MCC. AGS is going to backup in a rate-fail mode only, which you know. We're talking over the star check. Will have to get back with you on that. If, for some reason, there is no PC-2, you have a free-return trajectory with the landing at 152:02:00, and that would be after a small midcourse-5, which would probably be around 4 feet per second at 93 hours. And you have recovery forces in the Indian Ocean; you're in good shape there. And the Indian Ocean is where this landing would be. Okay. You still with me?

Vance Brand (CAPCOM)

Okay. After PC plus 2, there are no trim requirements; and, if you have a shutdown during PC plus 2, subsequent midcourse maneuvers required with—Well, the earliest one would be PC plus 4. If you don't do a PC plus 2, but we still want to do one—MCC later. At PC plus 4, the increase in DELT—in DELTA-V, or the penalty, would be about 24 feet per second, with a landing in the mid-Pacific at 142:46:30. Now, you should expect new pads, state vectors, and targets for PC plus 2 at about GET 78. Over.

Jack Swigert (CMP)

Tell them to stand by.

Fred Haise (LMP)

Okay. How do you read?

Fred Haise (LMP)

Okay. Burn rules. We should shut down for the following: if we have the thrust monitor at 77 percent or below; number 2, if the DPS propellant ullage pressure is less than 160 psi; 3, if the fuel oxidizer DELTA-P is greater than 25, and that'll be a ground callout; 4, if the attitude error is plus or minus 10 degrees except for starting transients. Okay. Rate limits are plus or minus 10 degrees per second. And we're to shut down with the following alarms: an ENGINE GIMBAL light, an ISS with a PROGRAM ALARM, an LGC, a CES DC, and an inverter light, if it's still on after we've tried switching inverters. If, during the burn, the engine shuts down when the NOUN 97 flashes, we should PRO, do manual ullage, and START pushbutton, push, and DESCENT ENGINE COMMAND OVERRIDE, open. If we don't do a PC-2, our next burn will it be at PC-4 for an added 24 foot per second. We'll land mid-PAC at 142:46:30. Okay. We'll have the AGS up for backup rate command, or rate damping, I guess. And the free return that we're on, if we don't—that we're on now, if we don't do PC-2 or 4, lands us at 152:02:00 in the Indian Ocean. And there's no trim requirements on this burn, and we should expect a new uplink and a new final maneuver pad from you at 178 hours.

Fred Haise (LMP)

Okay. I'm sorry, 1—Yes, 78 hours. It only seems like it's been that long.

Vance Brand (CAPCOM)

Okay, Fred. Your readback was correct.

Fred Haise (LMP)

Okay. And, Vance, did you ever have any LOS/AOS times, and—and a startup time for us to jump into this activation checklist?

Vance Brand (CAPCOM)

Okay. Let me—Let me poll the house again on that one.

Fred Haise (LMP)

Okay. One word is that the—In an optimum fashion there, going through that 2-hour activation generally took somewhere from about an hour and 15 to an hour 20.

Vance Brand (CAPCOM)

Okay. I guess then we ought to allow you a little more than that, huh?

Fred Haise (LMP)

No, I was thinking that we don't have to do about four pages of it, that we probably need just about that, and that will make up for the difference of any added time we need maneuvering et cetera.

Jim Lovell (CDR)

We'll need a—Can I get a flashlight? You got a flashlight. We might need a spare flashlight—Yes. Okay. We might need a spare flashlight: have you got one? Okay. Okay. The Sun has gone … down.

Jim Lovell (CDR)

Man, look at those stars. Houston.

Jim Lovell (CDR)

Roger. We are in the shadow of the Moon now. The Sun is just about set as far as I can see and the stars are all coming out.

Vance Brand (CAPCOM)

Okay. And if you are ready to copy, we have LOS/AOS times for you.

Vance Brand (CAPCOM)

Okay. LOS 77:08:35, AOS 77:33:10. Sunrise—First I'll give you sunset which is past, but that was supposed to be at 76:32:45 and sunrise 77:16:48.

Fred Haise (LMP)

Okay. LOS at 77:08:35, AOS at 77:33:10. Sunset at 76:32:45, sunrise at 77:16:48.

Vance Brand (CAPCOM)

Roger. We'll get back with you on the powerup time and, if you're ready to copy, have angles to load into NOUN 22 for your VERB 49 maneuver to burn attitude. Over.

Fred Haise (LMP)

Okay. Go ahead with the VERB 49 value.

Vance Brand (CAPCOM)

Okay. R1 plus 27210, R2 plus 35570, R3 plus 33010. Second item, as you know, due to maneuver with a PROCEED and a PROCEED; and, after your attitude, a reminder that P40 will not set you back to a narrow deadband. To get back to the 1.40-degree deadband, you have to use the procedure I gave you, which is VERB 21, NOUN 01, ENTER, 3011, ENTER. And 200, ENTER.

Fred Haise (LMP)

Okay. VERB 49, register 1, plus 27218; register 2, plus 35570; register 3, plus 33010; and to get the narrow deadband back we want a VERB 21, NOUN 01, ENTER, 3011, ENTER, 200 ENTER.

Vance Brand (CAPCOM)

Roger. And a correction on your—on your first number for register 1. That should be plus 27210. And another comment; after you get into the narrow deadband at that attitude, why, you might tell us where you see Nunki.

Jim Lovell (CDR)

Roger. Will do, Vance.

Fred Haise (LMP)

Okay. And you corrected register 1; it's plus 27210.

Jim Lovell (CDR)

And would you like us to make that maneuver at this time?

Jim Lovell (CDR)

It's down below us, isn't it?

Jack Swigert (CMP)

Can we have some more light in here now?

Fred Haise (LMP)

What do you see out your upper window?

Fred Haise (LMP)

Yes. It looks like—looks like the light is coming from around those clouds.

Jim Lovell (CDR)

Well, you won't get AOS/LOS until 77.

Jim Lovell (CDR)

Let's see, AOS is at 2 hours before the burn?

Vance Brand (CAPCOM)

Jim, we recommend you go ahead and make your VERB 49 maneuver, but just stay there in VERB 49 and don't go ahead to narrow the deadband just yet. And, when you're in that attitude, why, of course, then you can make your star check. And one other item is, I don't think we got back with you, but that hour 15 for powerup sounds fine with us.

Jim Lovell (CDR)

Okay. At this time, I'll start my VERB 49 maneuver, but will not narrow the deadband, and we will take a look at Nunki. Okay, Vance.

Fred Haise (LMP)

… how many lights you're going to see. You can coach Jim on that.

Jim Lovell (CDR)

Yes. I can just barely see it. I see Antares much better.

Jim Lovell (CDR)

Why is the wide deadband on? Stand by. Is—Is Scorpio moving down?

Jim Lovell (CDR)

What's that cloud I see over there?

I don't know. It looks like a Milky Way.

Vance Brand (CAPCOM)

Aquarius, Houston. Go ahead.

Jim Lovell (CDR)

Okay. We have completed our maneuver. We're in our wide deadband, and Nunki is close to the top of my display of the AOT. Right now, Antares seems to be more closer towards the center. However, we are in our wide deadband.

Vance Brand (CAPCOM)

Right; understand. We'll have to make a better check later, I guess.

Jim Lovell (CDR)

I can't for the life of me figure out what that dark stuff is.
