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?

Stand by, Fred.

Hell, is he still firing up there?

Okay, Fred. Negative on the activation on page 37. Go on to your RCS pressurize and then get your TCA breakers in and go to PGNS attitude hold.

Okay, Jack. How do you read?

Okay, Jim. This is Houston. We want you to load the DAP with 30120.

Load the DAP with 30120. Complete.

Okay. We need to change that CSM weight.

Okay, Aquarius. Your CSM weight is 63400.

And Jack's alive to take control the LM to stay away from gimbal lock. Over.

Affirmative. Take control of the LM. PGNS ATTITUDE HOLD.

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.

Say again.

Close, on panel 11, circuit breaker ATCA (PGNS).

ATCA (PGNS). Come on. Let's take it easy now.

Okay. We've got ATCA (PGNS) closed.

Yes.

Is that okay?

Yes.

Okay. Now I'm looking.

… okay …

How about plus?

No. …

Okay. It's already open.

Okay. Slow down.

Okay, Jack. We got it.

Yes.

Okay, Jim. How's the attitude control?

Okay, Jack. We've got attitude control now in the LM. We're going to try to rotate up through the bellyband.

Roger.

I like that sound like I got back there.

Odyssey, Houston. I've got a procedure for you.

Okay, Jack. I'm …

I want to go up this way to get away from that—the radios are powered, huh?

Yes.

Check your antenna?

Okay, Jack. Odyssey is ready to copy.

Okay, Jack. What we want you to do is close the reactants valve on fuel cell 2. Power down your inverters. Power down your battery relay bus. Battery ties, off, and pull your entry circuit breakers, entry battery circuit breakers A, B, and C.

Check the control, and make sure we don't go to gimbal lock, Fred.

Okay, Jack; understand. Close REAC valve circuit breakers in fuel cell 2. Power down inverters. Power down BAT relay bus. BAT TIES, OFF. Power entry and both running circuit breakers A, B, and C. All off.

That's affirmative, Jack. And close the reactant valve on fuel cell 2, there.

Okay. I'll do that, and Jack'll do that other.

Okay, Jack; on fuel cell 2, open circuit it.

Okay. Fuel cell 2 is open circuited. Do you want me to go through the standard shutdown procedure for the REAC valves and -

Odyssey, Houston. All you have to do is close the REACs valve on fuel cell 2.

Okay. CB REACs and vent REAC valves all closed.

Yes.

Yes.

… an hour and a half.

Okay.

Houston, Aquarius.

Go ahead, Aquarius.

Okay. Odyssey is completely powered down, according to the procedure that you read to Jack.

Roger; we copy. That's where we want to be, Jim.

And, Jack, have you all got good LM data down there now?

That's affirmative, Fred. We're getting good LM data.

Okay. In that case, I think I'll pull out some display breakers and just let you all keep an eye on things.

Roger.

He's turning his lights off now, too.

Stand by 1 on that, Fred.

Okay.
