Joe Kerwin (CAPCOM)

Aquarius, Houston. Go ahead.

Jim Lovell (CDR)

Roger. He just did the coarse aline. I'm going to the jettison attitude.

Joe Kerwin (CAPCOM)

Aquarius, Houston. I copied that you—that he's completed the coarse aline; he's going into the P52 now? Is that right?

Jim Lovell (CDR)

Let me check. I think he is.

Joe Kerwin (CAPCOM)

Okay. You're staying at your present attitude, aren't you?

Jim Lovell (CDR)

Yes. We'll—I'll stay in the present attitude.

Jack Swigert (CMP)

Okay, Houston. I got a 220 alarm here. …

Joe Kerwin (CAPCOM)

Odyssey, Houston. Have you set the drift light and the REFSMMAT light? Over.

Joe Kerwin (CAPCOM)

You were noisy; I didn't copy. Have you set the drift and REFSMMAT flag?

Jack Swigert (CMP)

Okay, Joe. I don't have a star in the sextant. I'm going to hunt for it in a minute.

Jack Swigert (CMP)

Okay, Joe. Can you give me any stars that I might try here?

Joe Kerwin (CAPCOM)

That's affirmative. Vega and Altair should be good. Vega is 36, Altair is 40.

Jack Swigert (CMP)

Okay. We'll give that a try.

Joe Kerwin (CAPCOM)

Okay. And you might look for them in the telescope if they're not in the sextant right off. They should be close to the crosshairs.

Jack Swigert (CMP)

Okay. I got all that material that's venting from the bottom of the command module.

Jim Lovell (CDR)

I have an RCS light, Houston.

Joe Kerwin (CAPCOM)

Okay, Jim. That's the one we warned you about some time ago. Low helium; no sweat.

Jack Swigert (CMP)

Okay, Houston. There's a star angle difference with stars 36 and 40.

Jack Swigert (CMP)

An odd maneuver, Houston.

Joe Kerwin (CAPCOM)

Roger that. Copy you're maneuvering to the LM JETT attitude. Is that right?

Jack Swigert (CMP)

I'm going to torque those gimbal angles.

Joe Kerwin (CAPCOM)

Torque them, babe, full stroke gimbal.

Jack Swigert (CMP)

There it is. Okay. I'll do a star check.

Joe Kerwin (CAPCOM)

Okay, Odyssey. You're suddenly ahead of the time line.

Joe Kerwin (CAPCOM)

Odyssey, Houston. Request OMNI Bravo.

Jack Swigert (CMP)

Okay, Houston. The sextant star check passes.

Jack Swigert (CMP)

I did a star check, and it passes. It puts that star right in the telescope.

Joe Kerwin (CAPCOM)

Good enough. You can press on in the checklist, Jack.

Jim Lovell (CDR)

It's the command module's gimbal lock I'm worried about.

Joe Kerwin (CAPCOM)

Roger. If you concur, we would be inclined to recommend that you go to AGS for the maneuver because you'll have to be there later on anyway.

Joe Kerwin (CAPCOM)

And AGS PULSE is the recommendation.

Jim Lovell (CDR)

We're having trouble maneuvering, Joe, without getting it in gimbal lock.

Jim Lovell (CDR)

You picked a lousy attitude, though, to separate.

Joe Kerwin (CAPCOM)

Well, we apologize. Just take your time. Jim, we've got time now.

Jim Lovell (CDR)

Houston, why can't I stay in PGNS ATT HOLD for the LM attitude hold?

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Okay. Our recommendation is that you stay in AGS for the LM JETT simply because we've thought it through. We've got the right deadbands and all set up. Over.

Jim Lovell (CDR)

Okay. It's a lot easier for me to maneuver in PGNS, Joe, than it is AGS.

Joe Kerwin (CAPCOM)

Yes. You can maneuver in PGNS, Jim. I'm sorry, I thought you were talking about the ATT HOLD and the LM JETT afterward. You can maneuver in PGNS if you want to.

Jim Lovell (CDR)

I want to get way over here, Joe. To prevent him into gimbal lock, I have the yaw at about—I'd say about almost 50 degrees.

Joe Kerwin (CAPCOM)

Roger that. Just stay out of gimbal lock and that 45-degree isn't critical—the out of plane, that is.

Joe Kerwin (CAPCOM)

Odyssey, Houston. Request OMNI Charlie.

Jack Swigert (CMP)

Okay. Going OMNI Charlie.

Joe Kerwin (CAPCOM)

Roger. That's VERB 46. Roger. Aquarius, Houston.

Joe Kerwin (CAPCOM)

Okay, Jim. The particular DAP configuration we have set up now is using more fuel than we'd like out of system B. We'd like you to reconfigure the DAP to 30021. Over.

Joe Kerwin (CAPCOM)

We'd like to have you turn the optics power off until you need them again, and we would like to have you check the RCS ring 1 and 2 temps for us. Over.

Jack Swigert (CMP)

Optics power going off.

Jack Swigert (CMP)

Okay, Joe. Our ring 1 is 50; ring 2 is plus 42.

Joe Kerwin (CAPCOM)

Ring 1 is 50; copy. What was the other?

Jim Lovell (CDR)

Okay, Houston; Aquarius. I am at the LM SEP attitude and I'm planning on bailing out.

Joe Kerwin (CAPCOM)

Okay. I can't think of a better idea, Jim.

Jim Lovell (CDR)

I'll go to AGS ATT HOLD, if you want me to.

Joe Kerwin (CAPCOM)

We recommend that, Jim.

Joe Kerwin (CAPCOM)

Okay, Aquarius; Houston. In AGS ATT HOLD, we recommend WIDE DEADBAND. Over.

Jim Lovell (CDR)

I'm in the AGS DEADBAND.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Don't forget the …

Fred Haise (LMP)

You need to relay something downstairs, Jim?

Joe Kerwin (CAPCOM)

Okay. Our troops would like to have you go to the SYSTEMS TEST METER and read out the injector temps on RCS for us.

Jack Swigert (CMP)

Okay, Houston. Let me read out the injector temperatures for you.

Jack Swigert (CMP)

5 Charlie, 4.2; 5 Dog, 4.6; 6 Alfa, 4.3; 6 Bravo, 4.3; 6 Charlie, 3.6; 6 Dog, 3.6.
