Spacelog Apollo 13

Aquarius, Houston. Go ahead.

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

Copy that.

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

Let me check. I think he is.

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

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

Roger that.

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

Roger that.

… …

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

Odyssey, Houston.

… flag.

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

Roger that, Jack.

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

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

Okay. We'll give that a try.

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.

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

I have an RCS light, Houston.

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

Oh, okay.

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

How about that, baby.

An odd maneuver, Houston.

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

That's affirm —

That's affirm.

I'm going to torque those gimbal angles.

Torque them, babe, full stroke gimbal.

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

Okay.

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

Odyssey, Houston. Request OMNI Bravo.

I am OMNI Bravo, Jim.

Okay.

Okay, Houston. The sextant star check passes.

Say again, Jack.

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

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

Find out LM gimbal lock, Jim.

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

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

Okay.

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

Stand by on that, Jim.

Aquarius, Houston. Over.

Go ahead.

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.

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

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.

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.

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

Odyssey, Houston. Request OMNI Charlie.

Okay. Going OMNI Charlie.

Thank you.

There.

Okay. Good.

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

Go ahead.

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.

Thank you.

Odyssey, Houston.

Go ahead.

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.

Optics power going off.

Okay.

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

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

42.

Got it. Thank you.

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

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

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

We recommend that, Jim.

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

I'm in the AGS DEADBAND.

Roger.

Aquarius, Houston. Don't forget the …

You need to relay something downstairs, Jim?

Odyssey, Houston.

Go ahead, Joe.

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

Okay. Okay. In work.

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

Go ahead.

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