Jack Lousma (CAPCOM)

Okay, Jim. I think I'm reading Jack, now. But what we want him to do is to give us a command reset. And then power down the CMC, power down the IMU, turn the IMU heater off, leave battery A on. Over.

Jack Swigert (CMP)

That's just about 80—in fact, 82 hours out of the two primary cartridges. That's two guys. 44 is what LC8 got. That would be 88 hours. We got a secondary. You're right. We're listening.

Jack Swigert (CMP)

They can stand it—Go ahead?

Jack Lousma (CAPCOM)

Yes, Jack. Did you copy down about the CMC IMU?

Jack Swigert (CMP)

Yes, Jack. I read it back twice to you. Command reset, which I've done. I'm about to power down the IMU, power down the CMC, turn the IMU heaters off, leave BAT A on.

Jack Lousma (CAPCOM)

That's affirm. Thank you.

Jack Swigert (CMP)

Okay. I just got a MASTER ALARM and MAIN BUS A UNDERVOLT. And I'm starting to power down, now. —

Fred Haise (LMP)

We've lost—The only advantage to doing it early; if we can power back—the LM back down. The only advantage doing it early is you can do a big burn now and a midcourse and then power the LM down. Otherwise, we got to keep the LM powered up clear until we get around the Moon. Plus it would be inside on the burn. I just hope the G&N hangs up on—hangs in on this one—I'd sure hate to do that one manual.

Jack Lousma (CAPCOM)

Odyssey, Houston. Couple circuit breakers for you. On panel 276, on our INSTRUMENTATION POWER CONTROL, open CB number 3 and number 4.

Jack Swigert (CMP)

Okay, Houston. Panel 276, INSTRUMENTATION out and reset —

Fred Haise (LMP)

— CB-3 and CB-4 are open.

Jack Lousma (CAPCOM)

That's affirmative, Odyssey. And also get your SCS electronics package and power off, and your FDAI POWER/GPI off, and your AUTO jet SELECT, all 16 off.

Jack Swigert (CMP)

Okay. Well, wait a second. Let me—Let me get the CMC power down.

Fred Haise (LMP)

I wonder how much that's going to bring this up, here.

Jim Lovell (CDR)

Jack, while he's doing that, copy down what you just said again. I want to write it down.

Jack Lousma (CAPCOM)

Aquarius, we need to get your sublimator powered up, Activation page 20 and Activation page 21, step 3. Over.

Jim Lovell (CDR)

Roger. Activation page 20 and Activation page 21, step 3, sublimator.

Jack Swigert (CMP)

That's Activation, page 20? Okay, Jack. Now I have to power down IMU. I have no control at all. I'm going to turn my 16 jets off, Say again the other things you wanted?

Jack Lousma (CAPCOM)

Okay, Jack. We'd like you to turn off your O2 tank 2 heaters and fans. Correction—tank 1. Turn the fans and heaters off.

Jim Lovell (CDR)

Okay. And, Jack, can we turn on the FDAI circuit breakers so we could have a ball to see if we go to gimbal lock or not?

Jack Swigert (CMP)

Houston, he's going to give a 16 NOUN 20, Jack. And, okay, I've got O2 heaters and fans off in tank 1.

Jim Lovell (CDR)

And, Jack, let me know if you get close to gimbal lock, would you?

Jack Lousma (CAPCOM)

Jim, we don't want you to power down the ball in the LM. We wanted you to power down the ball in the CSM.

Jack Swigert (CMP)

Jack, they haven't powered down —

Jim Lovell (CDR)

Jack, we don't have the balls powered up in the LM.

Jack Swigert (CMP)

I have the CMC and IMU in the command module is powered down. The heaters are out.

Fred Haise (LMP)

And the EVAP flow valve, that's open now, and I've undone my suit hoses here and opened up the suit flow valves; so, we got air flowing in the LM now.

Jack Swigert (CMP)

Okay, Jack. Will you say again the SCS items you wanted me to power down?

Jack Swigert (CMP)

Okay, Houston. Do you read Odyssey?

Jim Lovell (CDR)

Hello, Houston. How do you read?

Fred Haise (LMP)

His gimbal lock and ours are different, Jim.

Jack Lousma (CAPCOM)

Apollo 13, Houston. Say again, please. You were cut out.

Jack Swigert (CMP)

Okay, Jack. Do you want me to proceed by the SCS powerdown checklist? I did not copy the SCS items you wanted me to power down.

Jack Lousma (CAPCOM)

Okay, Odyssey. We want to go SCS ELECTRONICS POWER, OFF.

Jack Lousma (CAPCOM)

FDAI POWER/GPI, OFF. AUTO jet SELECT, 16 —

Jack Lousma (CAPCOM)

— OFF. And all your ROTATIONAL CONTROL POWER, OFF.

Jack Swigert (CMP)

It's done. ROTATION CONTROL POWER, DIRECT, and AUTO …, OFF.

Jim Lovell (CDR)

Okay, Jack. Tell me there. We need to know when we're getting close to gimbal lock in the LM. We have no balls right now.

Jack Lousma (CAPCOM)

Okay. We want you to power up your eight-ball. We want you to get your RCS heaters on. Pressurize the RCS and open up the MAIN SOVs. Over.

Fred Haise (LMP)

Okay, Jack. I got two commander FDAI breakers in, AC and DC, and the two GASTA breakers in AC and DC and next you'll want the RCS heaters all on with the—pressurize the RCS and then the MAIN SOVs open. And I think they're already open.

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Jim Lovell (CDR)

Jack, are you reading LM gimbal angles?

Jack Swigert (CMP)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

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.

Fred Haise (LMP)

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

Fred Haise (LMP)

We got to get this pressurized.

Jack Lousma (CAPCOM)

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.

Jim Lovell (CDR)

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.

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Multiple speakers

Fred Haise (LMP)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

Go ahead, Odyssey.

Jack Swigert (CMP)

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.

Jack Lousma (CAPCOM)

Roger, Jack. Just maintain attitude.

Jack Swigert (CMP)

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

Jack Lousma (CAPCOM)

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.

Jim Lovell (CDR)

That's been completed, Jack.

Fred Haise (LMP)

Okay. The RCS is pressurized now.

Fred Haise (LMP)

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

Fred Haise (LMP)

Hell, is he still firing up there?

Jack Lousma (CAPCOM)

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.

Jim Lovell (CDR)

Okay, Jack. How do you read?

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

Load the DAP with 30120. Complete.

Fred Haise (LMP)

Okay. We need to change that CSM weight.

Jack Lousma (CAPCOM)

Okay, Aquarius. Your CSM weight is 63400.

Jim Lovell (CDR)

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

Jack Lousma (CAPCOM)

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

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

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

Unidentified crew member

Oh?

Jim Lovell (CDR)

Are you firing anything?
