Spacelog Apollo 13

Roger. And, Fred-o, get the TCA breakers in last. Please.

Roger, Jim. I'm holding open those until you give me a further word anyway. I'm just going to pressurize right now.

Jack, are you reading LM gimbal angles?

— … power off, come down here and … the audio …

Okay, Aquarius. I have some gyro torquing angles and the Odyssey is powered down, attitude-control-wise, so LM's got attitude control now.

Aquarius, Houston.

Go ahead, Jack.

Okay. We want you to know that we got some gyro torquing angles for you. And we want you to tell us when you got attitude control in the LM.

Okay. We're still working on the pressurization. I'm getting Jim on the horn here so he can help out, there.

Roger.

Wonder why.

We got to get this pressurized.

Houston, Aquarius.

Stand by 1, Aquarius, Odyssey. We'd like you to go DIRECT RCS and hold your present attitude out the window until the LM gets RCS powered up. Go ahead, Jim.

Well, that's my question. We're not—Our 16 20 doesn't match our eight-ball here. We went to FDAIs ON, and we don't have our balls completely powered up. There may be a … and our angles don't look the same and we don't want to go into gimbal lock.

Roger. How far are you from RCS power up—RCS pressurization?

Okay, Jack. I'm right up to where it's MASTER ARM, ON; RCS, FIRE; —

…

— both LOGIC POWERs out … goes into normal circuit-breaker. … Do you want A in and then I'll fire them?

Okay, 13. You're both talking at once. One at a time, please.

Okay. Who's first?

Close LOGIC POWER A and B, Fred, and pressurize RCS.

Okay.

Go ahead, Odyssey.

Okay. I'm going to try to do the best I can. I've got a one-attitude reference I'm going to fly according to the lunar terminator.

Roger, Jack. Just maintain attitude.

What am I doing? I can't do that, anyway. Let's see, cross feed. Nope. Now, and -

Aquarius, Houston. We'll have to get some AC up so you can get a ball reading. Close your BUS TIE INVERTER circuit breakers, all four of them on panel 11. Close your AC BUS VOLT circuit breaker on panel 11. On panel 16, INVERTER 2, CLOSE. Select inverter 2. Over.

That's been completed, Jack.

Okay. The RCS is pressurized now.

Okay, Jack. Do you want us to proceed right on down the line with the RCS check-out and Activation 37 now?

We are.

And, Odyssey, request you coordinate with Aquarius on attitude control.

Okay.

Roger.

Okay. I don't see where you're firing these things …

Oh?

Are you firing anything?

I don't think so.

Okay. I got DIRECT.
