Joe Kerwin (CAPCOM)

Okay, Jim. In the LM, there we have—We show battery 3 only drawing about an amp, and we think it's probably time to get it off the line; battery 3 to OFF/RESET. Over.

Jim Lovell (CDR)

Battery 3 is OFF/RESET.

Jim Lovell (CDR)

Just how's our power consumption, Houston, just out of curiosity?

Joe Kerwin (CAPCOM)

I'll verify it, Jim. I'm sure it's okay.

Joe Kerwin (CAPCOM)

Okay, Aquarius; Houston. With the present amount of power you've got in the LM, which is over 500 amp-hours, and the rate you're using them, we figure you've got almost 12 hours of power left.

Jim Lovell (CDR)

Twelve hours, huh? We could reenter with it.

Joe Kerwin (CAPCOM)

That's enough for two touch-and-goes and a full stop, Jim.

Jim Lovell (CDR)

That's right, Joe; if you could dig a crater like Cone Crater, I could might hit it.

Jim Lovell (CDR)

Jack reports that he thinks he can see Altair.

Jim Lovell (CDR)

He says, he thinks he can see Altair.

Joe Kerwin (CAPCOM)

Okay. I'll take back the “very,” but I'll leave the “good.”

Jim Lovell (CDR)

I ran back there to take a look and see what I could see in the—in the scanning telescope. It looks pretty grim back there right now. It might be that we have to go with the coarse aline, and maybe computation of some fine aline docking angles, if we have time.

Joe Kerwin (CAPCOM)

Okay. We'd like to do that, too. Wait a minute; stand by, Jim.

Joe Kerwin (CAPCOM)

Aquarius, Houston. How do you read?

Jim Lovell (CDR)

I read you loud and clear.

Ken Mattingly

Okay. What we'd like to do, Jim, is—We'll go ahead and get the coarse aline to the gimbal angles that—that you're going to be holding for us; and we'll get the platform up, and then when you call P52 and you use PICAPAR, it probably won't be close enough to put the star in the sextant, but if you can see any kind of a bright star in the general vicinity,—and like general vicinity, I mean 2 to 3 degrees from the center of the telescope, so that you have some clue as to which way to go, then the identification problem shouldn't present much of a—of a difficulty. And once you get the thing in the sextant, then you can go ahead and treat it like any other PICAPAR.

Jim Lovell (CDR)

That sounds great, Ken. One little problem: there's all sorts of bright objects floating around us, and also that just staring at part of Aquarius; it's just reflecting light like mad. We can give it a try. There's no problem there; if we can see it, we'll get it.

Ken Mattingly

Okay. And in—in the event that that doesn't work, we're standing by with the original scheme, a set of LM FDAI angles to fly to that'll point the command module optics at the Moon and the Sun; so we can always go back to that.

Ken Mattingly

And, Aquarius, Houston. We'd like you to verify the SUIT RELIEF valve to closed. Over.

Jim Lovell (CDR)

Stand by. It's closed.

Jim Lovell (CDR)

Okay, Houston; Aquarius.

Jim Lovell (CDR)

We'll go with your original 91-degree angle, if you have the stars figured out, and the coarse aline angle for it.

Joe Kerwin (CAPCOM)

Okay. Roger that, Jim. Then at—at your convenience here, we'd like you to go to that attitude, as close as you can get, and call up a NOUN 20 for us.

Jim Lovell (CDR)

Okay. I take it that, if—if Jack cannot see stars at this attitude after you give him the coarse aline angles, we're just not going to read down to you our gimbal angles and have you figure out a target angle for Jack, but you want him to do sighting on the Moon and the Sun. Is that correct?

Joe Kerwin (CAPCOM)

That's roughly correct, Jim. Jack will coarse aline at that attitude. This is what we're having you maneuver to the—to that attitude for. We're going to compute coarse aline gimbal angles and pass them up to him, and the first thing he'll do when he gets there, per his checklist, is to coarse aline his platform. Then he'll go into the P52, and, if he can't see stars, we will quickly pass up to you the—your FDAI angles to put him in the Moon-view attitude, and he'll do his P52 on the Moon, and then have you maneuver on the Sun and complete the P52 of the Sun.

Jim Lovell (CDR)

Okay. But I'm going to have to maneuver to the Moon to help him out.

Joe Kerwin (CAPCOM)

Oh. That's—That's affirmative. If he can't see stars at the—at the SEP attitude that—that you'll be holding, you'll have to maneuver to the Moon attitude and then to the Sun attitude for him.

Joe Kerwin (CAPCOM)

Just like to mention that, even if, for some reason, we run out of time or something and don't complete the Moon-Sun P52, Jack will have a platform coarse aline to the entry REFSMMAT, which we feel will be plenty good enough.

Jim Lovell (CDR)

Roger. That's my feelings, too.

Jim Lovell (CDR)

Hello there, Houston.

Joe Kerwin (CAPCOM)

Hi! Jim, we—We've gone ahead and computed the CSM coarse aline gimbal angles based on your being at the service module SEP attitude at the time that Jack cranks up the computer and—and coarse alines the IMU. That is, we assume that you're going to be at roll, 0; pitch, 091; yaw, 0; and, if you concur on that, I'd like to pass up the angles for—for Jack to have.

Jim Lovell (CDR)

Okay. I'll be there to the best of my ability.

Joe Kerwin (CAPCOM)

Good show. You ready to copy?

Joe Kerwin (CAPCOM)

Okay. CSM coarse aline angles: ROLL, plus 298.95; PITCH, plus 271.30; YAW, plus 000.20.

Jim Lovell (CDR)

Okay. The command module angles will be: ROLL, 298.95; PITCH, 271.30; and YAW, 000.20.

Joe Kerwin (CAPCOM)

That's affirmative, and that's for his VERB 41 NOUN 20 when he gets there.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Jim Lovell (CDR)

Go ahead, Houston; Aquarius here.

Joe Kerwin (CAPCOM)

Okay, Jim. We're getting about 9 minutes from the commencement of command module powerup, and we wanted to just mention to you for Jack's benefit that, although the batteries are looking real good, in case they're cool and have a little difficulty hacking the load just at first, we'd like him to monitor main bus voltage to 24 volts or above during the powerup procedure and, if it falls below, we'll have a couple of circuit breakers for him that—that will solve the problem.

Jim Lovell (CDR)

Okay. And I take it you're also monitoring main bus voltage.

Joe Kerwin (CAPCOM)

Negative. Not in the command module at this time, because we don't call up telemetry until a little bit later on.

Jim Lovell (CDR)

Ah so. That's right; I forgot. Okay. I will tell him.

Joe Kerwin (CAPCOM)

Okay. You're GO to start powering up the command module.

Jim Lovell (CDR)

Right-o. We're starting now.

Fred Haise (LMP)

Okay. We have LM power breakers.

Fred Haise (LMP)

Okay. Houston, you're looking at it.

Fred Haise (LMP)

Okay. That's—That's it, Joe.

Joe Kerwin (CAPCOM)

Roger. We have command module AOS. Request OMNI Charlie in the CM. Over.

Jim Lovell (CDR)

OMNI Charlie. Okay. Standby.

Jim Lovell (CDR)

That was sent through a new onboard communication system known as yelling through the tunnel.

Jim Lovell (CDR)

I've got Fred up there with Jack now helping to power up the CM, and I'm staying down in good old Aquarius.

Joe Kerwin (CAPCOM)

Just to inform you. We've got data from the—from Odyssey, and it looks good.

Jim Lovell (CDR)

Houston, Aquarius. Odyssey is trying to call. Can you read them?

Joe Kerwin (CAPCOM)

Negative. Don't read Odyssey yet; has he got his intercom panel configured?

Jim Lovell (CDR)

I'll doublecheck. They're hearing you.

Joe Kerwin (CAPCOM)

Okay. Good deal. I don't hear them, yet.

Jim Lovell (CDR)

Are you ready for an E-MEMORY dump, VERB 74?

Joe Kerwin (CAPCOM)

Stand by for just 1 minute, Jim.

Jim Lovell (CDR)

We've got a lot of things to do, Houston.

Joe Kerwin (CAPCOM)

I know it. Okay, Aquarius; Houston. Recommend in Odyssey that he switch the POWER AMPLIFIER to LOW. Over.

Jim Lovell (CDR)

POWER AMPLIFIER to LOW.

Jim Lovell (CDR)

It's been switched to LOW, Houston.

Joe Kerwin (CAPCOM)

Roger. Okay. Verify the POWER AMP talkback is gray, Jim.

Jim Lovell (CDR)

Okay. That's verified.
