Jack Swigert (CMP)

Joe, how far out are we now and how fast are we closing?

Joe Kerwin (CAPCOM)

Okay, Jack. The plot shows you about 130 000 miles out, which is about, gee, 10 000 closer than you were when I came on a couple of hours ago. And let me check with FIDO for your rate of closure.

Joe Kerwin (CAPCOM)

Your smiling FIDO says you're making 5040 in a 5000-mile zone

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Roger, Jack. Hate to keep bugging you, but we would like another volts and amps reading. Over.

Jack Swigert (CMP)

Okay. We'll get it for you.

Jack Swigert (CMP)

Joe, did our sticky MOD on that—those CO2 canisters work? I'm sorry—…

Joe Kerwin (CAPCOM)

Jack, I think you asked if the canister MOD was working and the answer is, it sure as hell is.

Jack Swigert (CMP)

Okay, Joe. I got the voltage. It's 39.0 amps and 1.75.

Jack Swigert (CMP)

Houston, do you read Aquarius?

Joe Kerwin (CAPCOM)

Aquarius, Houston. That's affirmative.

Jack Swigert (CMP)

Okay. We had a dropout there for a few minutes. … on either antenna.

Joe Kerwin (CAPCOM)

Gee whiz, Jack, I—when did it happen? Over.

Jack Swigert (CMP)

Just now. I just got you back.

Joe Kerwin (CAPCOM)

Okay. We had a handover, but that was about a half an hour ago, and I didn't call you on it. Let me check with INCO and see if he thinks everything's okay. Your COMM sounds just as good as it's ever been.

Jack Swigert (CMP)

Yes. I'm in real good shape.

Joe Kerwin (CAPCOM)

Roger. We're checking into it. We think we lost lock in Madrid for a while, and we've got it back now.

Jack Swigert (CMP)

You might also check with FIDO whether we … perigee …

Joe Kerwin (CAPCOM)

You're getting a little weak. Did you say you wanted to verify what—what your vacuum perigee is? Over.

Joe Kerwin (CAPCOM)

Okay. The good FIDO gives us a vacuum perigee at the present time of 23.6 with a flight path angle of minus 6.25 degrees. That's without a midcourse. He's kind of tossing around the idea of doing a midcourse-7 maneuver at 5 hours before entry. If we do it, it looks like it won't be more than 2 feet per second. Over.

Joe Kerwin (CAPCOM)

And, Jack, Houston. We verified that that COMM problem was a ground problem.

Jack Swigert (CMP)

Okay. Thank you. That FIDO is really cooking today.

Joe Kerwin (CAPCOM)

Oh, he's having a ball.

Jack Swigert (CMP)

It must be because we haven't made any waste water dumps.

Jack Swigert (CMP)

You can tell Jay and David that I went for a whole flight and didn't use the bathroom.

Joe Kerwin (CAPCOM)

(Laughter) He copies that. David's here; he says you've kept him so busy he hasn't had time to work on his stereo all week.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Jack, we'd like another volts and amps reading at your convenience.

Jack Swigert (CMP)

Okay, Houston. It's 39.2 volts; 1.6 amps.

Joe Kerwin (CAPCOM)

Okay. Thank you. We copy; 39.2 volts, and 1.6 amps.

Jim Lovell (CDR)

I just relieved the watch; just thought I'd find out how things are going.

Joe Kerwin (CAPCOM)

Okay, Jim. Good morning; and understand you relieved the watch, and the rest was kind of blurry. Did you have any questions?

Jim Lovell (CDR)

No questions, Joe. Just …

Joe Kerwin (CAPCOM)

Okay. That was—That was loud and clear, that one there. Now we don't have a heck of a lot going on as you know we're working on the entry procedures. I've got preliminary copies, but we're not ready to pass—to pass it up to you. Looks like you're about 125 000 miles out, starting to—starting to really pick up speed, and the Astros won last night, and that's about all I've got. Over.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Okay, Jim. It's about time, at your convenience, for another volts and amps reading on the command module. For your information, we put 6 amp-hours back in the battery already and we've got about 14 to go. It's looking real good, and I also just got the word that the entry weather tomorrow is looking better all the time. Really looks great.

Jim Lovell (CDR)

That's good. When I went to bed last night, … a lot of rain …

Joe Kerwin (CAPCOM)

Couldn't copy that, Jim. Sorry.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Go ahead.

Jim Lovell (CDR)

Roger. 39.2 on the volts; 1.4 on the amps.

Joe Kerwin (CAPCOM)

39.2 and 1.4. Thank you.

Joe Kerwin (CAPCOM)

Roger. Just for your information, in case it happened when you were off watch, the master caution circuit breaker is still pulled, and we're seeing the—the malfunction indication on the descent battery now, but all the parameters still look just as good as ever, and that's just for information.

Jim Lovell (CDR)

Okay. I see the battery light flickering now.

Joe Kerwin (CAPCOM)

Okay. Recommend you ignore it.

Jim Lovell (CDR)

Okay.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Jim, it's volts and amps time again, at your convenience.

Joe Kerwin (CAPCOM)

Aquarius, Houston. If you gave me those readings, I didn't copy them. Over.

Jim Lovell (CDR)

Houston, Aquarius. Do you read?

Joe Kerwin (CAPCOM)

Aquarius, Houston. Okay; go ahead.

Jim Lovell (CDR)

Volts, 39.3; amps, 1.25.

Joe Kerwin (CAPCOM)

Okay. Copied 39.3 and 1.25. Jim, did Jack tell you what your trajectory looks like? Over.

Jim Lovell (CDR)

Haven't got up to … on it. How about giving me a rundown?

Joe Kerwin (CAPCOM)

Okay. We are looking at a vacuum perigee right now of 23.6; flight path angle of minus 6.25; and if we decide we want to trim that up, we're looking at a midcourse of about 2 feet per second. Your consumables, of course, are getting better all the time; we've got 163 hours of water, 230 hours of oxygen, and 172 hours worth of electrical power. Over.

Joe Kerwin (CAPCOM)

Aquarius, Houston. Over.

Joe Kerwin (CAPCOM)

Okay, Jim. We would like to get another check from you on the propellant tank temperatures, as we did yesterday. And the procedure is to, on panel 16, circuit breaker PROPELLANT, DISPLAY/ENGINE, OVERRIDE/LOGIC to close. Then go to your display and read the tank 1 and tank 2 temperatures for us, and then open the circuit breaker again. Over.

Jim Lovell (CDR)

Okay. I'm closing now—the DISPLAY/ENGINE, OVERRIDE/LOGIC.

Jim Lovell (CDR)

Okay. And the reaction control temperatures are 65 in A and 65 in B.

Joe Kerwin (CAPCOM)

Okay, Jim. We'd like the descent tank temperatures, too. Over.

Jim Lovell (CDR)

67; oxidizer is 63; descent tank 1 … is 64; the oxidizer is … Did you copy? Over.

Jim Lovell (CDR)

Hello, Houston. Did you copy the—the DPS display temperatures?

Joe Kerwin (CAPCOM)

Jim, I copied 63 and 64, which I think were the descent 1 temps, and that's all I got.

Jim Lovell (CDR)

Okay. I'll go over it again. I'm on descent 1, now and fuel is about 64, and oxidizer is 65, and I'll go to descent 2 —

Joe Kerwin (CAPCOM)

Okay. Thank you very much —

Jim Lovell (CDR)

— our descent 2. Okay. I've got descent 2 now right up on 67 and 66.

Joe Kerwin (CAPCOM)

Roger. We copy that, and once again we'd like to get the volts and amps check in the command module. Over.

Jim Lovell (CDR)

Okay. I'm going to go up there and get it. Jack is—and Fred are asleep, so I'll be off the air a minute.
