Jack Lousma (CAPCOM)

That's affirmative, Jim.

Jim Lovell (CDR)

Activation 11, omit step 1, do the rest. Is that correct?

Jim Lovell (CDR)

Do Activation 12 and Activation 13, step 1.

Jack Swigert (CMP)

Okay, Jack. Pressure in tank 1 is approaching 100 psi. What's going to be the symptoms of this fuel cell starting to drop off?

Expand selection up Contract selection down Close
Jack Lousma (CAPCOM)

Stand by, Jack. We'll get the word on that.

Jack Lousma (CAPCOM)

And, Jim, when you get to the end of that procedure, we'd also like to have you put the DEMAND REGs to CABIN.

Jim Lovell (CDR)

DEMAND REGs to CABIN. Roger.

Jim Lovell (CDR)

Jack, was that Activation 1, step 3 only, or all of Activation 1?

Jack Lousma (CAPCOM)

That's go all the way down to step 3, Jim.

Jim Lovell (CDR)

Activation 1 to step 3. Roger.

Jim Lovell (CDR)

Houston, Apollo 13. Never mind.

Jim Lovell (CDR)

Oh, we were curious about Activation 11 on the VHF.

Jim Lovell (CDR)

— … Jack. It's got—Okay.

Jack Lousma (CAPCOM)

Jack, this is Houston. We want you to keep the IMU up and keep the lights on so you can see in there, and leave battery off—battery A off and, at the appropriate time, we'll put it on MAIN A. And we're going to keep the IMU up so's we can get a coarse aline in the LM.

Jack Swigert (CMP)

All right. Real good. Right now, we're charging battery A. Do you want to discontinue that?

Jack Lousma (CAPCOM)

Discontinue the charge on battery A, Jack.

Jack Swigert (CMP)

Okay, Jack. I discontinued charge on battery A. You give me the call and I'll turn BUS TIE AC on.

Jack Lousma (CAPCOM)

Roger. And we want you to keep the lights up and the IMU on.

Jack Lousma (CAPCOM)

And, Jack, we'd like you to leave the COMM configuration as is until we get COMM with the LM.

Jack Lousma (CAPCOM)

And, 13, this is Houston. I've got another procedure for the LM. A short one.

Jim Lovell (CDR)

Okay. Ready to copy, Jack.

Jack Lousma (CAPCOM)

Okay. On panel 11, we'd like you to close the LGC DSKY circuit breaker. Then we want you to go to Activation 25; do steps 1, 2, and 3. Then go to Activation 30, and that will give us a docked IMU coarse aline. Over.

Jim Lovell (CDR)

Roger. Panel 11, close LGC circuit breaker. Activation 25, do steps 1, 2, 3, and then do complete Activation 30. Is that correct?

Jack Lousma (CAPCOM)

That's affirmative. On panel 11, LGC DSKY circuit breaker closed.

Jack Lousma (CAPCOM)

And in the LM, let's go to panel 11 and close the SUIT FAN circuit breaker and get suit fan 1 cranked up.

Jim Lovell (CDR)

Okay. Panel 11, close SUIT FAN circuit breaker, and we'll get the suit fan cranked up.

Jack Lousma (CAPCOM)

And, Jack, in the CSM, go to BYPASS on the radiators and turn your GLYCOL PUMP off.

Jack Swigert (CMP)

Okay. Pull the BYPASS; GLYCOL PUMP going off.

Jack Lousma (CAPCOM)

And, 13, in the CSM, we want to verify that all the fuel cell pumps are off, and we want to have you turn off the O2 fans in the tank 2.

Jack Swigert (CMP)

Okay. Tank 2 fans going off. Okay. That leaves me with tank 1 fans on the tank 1 heaters on.

Jack Swigert (CMP)

Fuel cell 2 pump going off now.

Jack Lousma (CAPCOM)

Jack, leave them both on in tank 1.

Jack Lousma (CAPCOM)

13, Houston. We've got AOS on the LM here.

Jack Lousma (CAPCOM)

And, 13, this is Houston. In the LM, we'd like to have 12, step 3, which is get the batteries on high taps. Over.

Jim Lovell (CDR)

How you going there? Activation 12, step 3.

Fred Haise (LMP)

Okay. And, Jack, how do you read from Aquarius?

Jack Lousma (CAPCOM)

Aquarius, Houston. Say again, please.

Fred Haise (LMP)

Okay. I was just making a COMM check here. I'm on high voltage taps.

Jack Lousma (CAPCOM)

Roger. We see them, Fred, and I'm reading you loud and clear.

Fred Haise (LMP)

Okay. Didn't think I'd be back this soon.

Fred Haise (LMP)

Okay. What next, James? Coarse aline?

Jim Lovell (CDR)

Do it right. Take your time.

Jack Lousma (CAPCOM)

And, Aquarius, Houston. We'd like you to, on your alinement, can you continue right on through the fine aline Activation 31? Go right on through step 7. Over.

Fred Haise (LMP)

Okay. You want to go on 31 through step number 7, Jack.

Jack Lousma (CAPCOM)

That's affirmative. And, Odyssey, we've got another configuration for you. All 16 RCS AUTO SELECT OFF. All RCS heaters off. Over.

Jack Swigert (CMP)

Okay. I can verify all heaters off. Jack, I've got to keep a fairly minimum deadband until I get through this coarse aline.

Fred Haise (LMP)

Okay. VERB 41, NOUN 20. Okay. You want plus? Plus or minus? Plus 302.43? Is that right?

Fred Haise (LMP)

Okay. Let me enter it. Okay. What's the next one? Plus 347.78. 347.78. Okay. 081.3. Is that right? ENTER. Okay.

Jim Lovell (CDR)

Houston. Okay. I want you to doublecheck my arithmetic to make sure we got a good coarse aline. The roll CAL angle was minus 2 degrees. The command module angles were 355.57, 167.78, 351.87.

Jack Lousma (CAPCOM)

Okay, Jim. We copy the roll CAL at minus 2.0. The command module is 355.57, 167.78, 351.87.

Fred Haise (LMP)

Okay. VERB 41, we've done that. Okay.

Jack Lousma (CAPCOM)

Aquarius, Houston. Request high bit rate, please.

Fred Haise (LMP)

You want high bit rate?

Jack Lousma (CAPCOM)

That's affirmative, Fred. Won't cost us anything.

Jack Lousma (CAPCOM)

Odyssey, Houston. We'd like you to, on your COMM configuration, go to PRIMARY POWER AMP OFF, LOW BIT RATE, and DOWNVOICE BACKUP. Over.

Jack Lousma (CAPCOM)

And, Aquarius, we need your SUIT GAS DIVERTER to CABIN.

Jack Swigert (CMP)

All right. You got it.

Jack Swigert (CMP)

Houston. I've gone to PRIMARY POWER AMPLIFIER, OFF, LOW BIT RATE, DOWNVOICE BACKUP.

Jack Lousma (CAPCOM)

Okay, Jack. Thank you. And, Aquarius, your arithmetic looks good on the coarse aline, there.

Jack Swigert (CMP)

Okay. Okay stand by for an ENTER.

Jack Swigert (CMP)

Get the GET; we need the GET. What is it? What's that? 58? 58:07?

Jim Lovell (CDR)

Here are the gimbal angles. Command module, 356.69, 163.42, 346.67. Aquarius is 302.26, 345.92, 011.79. Over.

Jack Lousma (CAPCOM)

Okay, Jim. I got command module 356.65, 163.42, 346.67. Aquarius, 302.26, 345.92, 011.78.

Jim Lovell (CDR)

The LM middle gimbal is 011.79.

Jack Swigert (CMP)

Houston. … flashing.

Jack Lousma (CAPCOM)

Odyssey, Houston. We need a command reset on your—on your COMM, and then we'd like you to power down to CMC, power down the IMU, heaters off on the IMU, but leave the battery A on.

Jim Lovell (CDR)

Houston, this is Odyssey. Go ahead.

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 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?

Jack Lousma (CAPCOM)

And, Aquarius, check you ATCA (PGNS) breaker on panel 11 in.

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

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

Spoken on April 14, 1970, 4:57 a.m. UTC (51 years, 7 months ago). Link to this transcript range is: Tweet

Jim Lovell (CDR)

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

Jim Lovell (CDR)

Okay. Now I'm looking.

Jim Lovell (CDR)

Okay. It's already open.

Fred Haise (LMP)

Okay, Jack. We got it.

Jack Lousma (CAPCOM)

Okay, Jim. How's the attitude control?

Jim Lovell (CDR)

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

Jim Lovell (CDR)

I like that sound like I got back there.

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

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

Jack Swigert (CMP)

Okay, Jack. Odyssey is ready to copy.

Jack Lousma (CAPCOM)

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.

Jack Swigert (CMP)

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

Jack Swigert (CMP)

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.

Jack Lousma (CAPCOM)

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

Jim Lovell (CDR)

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

Jack Lousma (CAPCOM)

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

Jack Swigert (CMP)

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

Jack Lousma (CAPCOM)

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

Jack Swigert (CMP)

Okay. CB REACs and vent REAC valves all closed.

Fred Haise (LMP)

… an hour and a half.

Jim Lovell (CDR)

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

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Jack Lousma (CAPCOM)

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

Fred Haise (LMP)

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

Jim Lovell (CDR)

He's turning his lights off now, too.

Jack Lousma (CAPCOM)

Stand by 1 on that, Fred.
