Spacelog Apollo 13

Okay. VERB 49, yaw plus 27100, pitch plus 35500, roll plus 33000. And do you think it's cheaper to manually make that maneuver or take the 0.2-degree range and go in AUTO maneuver?

Fred, we're recommending AUTO maneuver. Over.

Okay. AUTO maneuver, and could you give me a GET right now.

Okay. I understand you want GET of the burn. Stand by 1.

That's negative, Vance. What is your clock reading right now?

Okay. When I give you a hack, it will be 73:59, and that's about 40 seconds away.

Okay. I understand you got it.

You want me to PROCEED one more time on that, Jack?

Roger. Yes, go ahead.

Oh, it's on; it's a center.

That's it, she's right on still. Okay. I have, too. That's better than I expected.

Okay. Let's do a VERB 74 and get out of here.

If we can. Go to P00? Okay. I'm going to go to -

…

737100. Roger. 35500, plus 33000. …

Okay. That's —

Yaw, pitch, and roll.

Let me see. No, that's yaw, pitch, and—Okay. Everything's … … That's roll, pitch, and yaw.

Roll, pitch, and yaw.

Everything … yaw.

The roll's going to be down here, but the yaw will be off the bellyband. … procedure, or don't you have a procedure?

Roll, pitch, and yaw, but drift's the one. That would be gimbal lock if it wasn't for being off …

And, Houston, I see that this maneuver gives us a roll of 27172, a pitch of 08301. Is that what they gave us?

This is Houston. Please repeat.

Houston, did you give us VERB 49 in yaw, pitch, and roll, or register 1, 2, and 3?

We gave it as yaw, pitch, and roll.

Okay. We wrote it as roll, pitch, and yaw.

Okay, Jim. We read it to you as yaw, pitch, and roll, and we should have given it to you registers 1, 2, and 3; but we did not. So register 1 is 33000, register 2 is 35500, and register 3 is 27100.

Okay, Vance. Register 1 will be 33000, register 2 35500, register 3 27100.

Hey, Fred? Stand by on that.

Okay. Plus 27100. Okay. Stand by. Right now you can enter …

Okay. Apollo 13, Houston.

Go ahead.

Okay, Jim. We sorted it out, and it is correct the way we gave you the first time. So, R₁ 27100, and in the LM, that's yaw; R₂ 35500, and that's pitch; R₃ 33000, and that's roll in the LM. Over.

I agree with you. Okay. 5018, it's there, and 5018, and that's what it will be. Okay.

That's right. That's VERB 49.

There are 25. 25, ENTER.

Okay. Plus 27100, plus 35500, plus 33000.

Okay.

So far we're … what can we do about it?

Apollo 13, Houston. You better watch that middle gimbal. Over.

Roger. We're watching that middle gimbal. We have as a roll, 27172. Our yaw is—that's register 3—3300. How did we get this?

And, Apollo 13. We have a procedure for you describing how to widen the deadband to 5 degrees later on. But stand by for that.

Apollo 13, you're heading for gimbal lock. You better stop everything.

Yes, we're back in ATT HOLD now. We're trying to stop it.

Roger.
