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)
-
Roger, Jack. Hate to keep bugging you, but we would like another volts and amps reading. Over.
-
Joe Kerwin (CAPCOM)
-
Jack, I think you asked if the canister MOD was working and the answer is, it sure as hell is.
-
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.
-
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.
-
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.
-
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)
-
Okay, Jim. Good morning; and understand you relieved the watch, and the rest was kind of blurry. Did you have any questions?
-
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)
-
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.
-
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.
-
Joe Kerwin (CAPCOM)
-
Okay. Copied 39.3 and 1.25. Jim, did Jack tell you what your trajectory looks like? Over.
-
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)
-
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.
-
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)
-
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.
-
Joe Kerwin (CAPCOM)
-
Okay. We copy 39.3 and 1.20. And, Jim, I've got one more item for information for you. At—In about 45 minutes or so, you will get an H2O quantity caution light on the descent tank. We expect this. It occurs at 16 percent. And it's no problem, because we intend to run the tank dry just for drill. To reset the—the light, on panel 2, just set the O2 H2O QUANTITY MONITOR to the CAUTION/WARNING RESET position and the light will go away. Over.
-
Jim Lovell (CDR)
-
Okay. I understand. We're going to get a H2O warning light here shortly, and I'll reset it.

Joe, you might pass to our friends in Crew Systems that lunar boots make great footwarmers.
-
Joe Kerwin (CAPCOM)
-
I guess you need them up there, too. Is—is anybody sleeping in the command module right now, Jim?
-
Jim Lovell (CDR)
-
Negative, Joe. It's just too cold in there. I got Fred stashed over here to my left. He's asleep and Jack's …
-
Joe Kerwin (CAPCOM)
-
Roger. Earth is here, also; and, Jim, it is time for another one of those volt/amp checks. For your information, we've got that battery back up to 30 amp-hours now. Over.
-
Joe Kerwin (CAPCOM)
-
Jim, Houston. Have you guys put on any extra clothes to try and ward off the nip of Jack Frost? Over.
-
Jim Lovell (CDR)
-
Well, the lunar boots and two pair of underwear, and everyone is … crawl into their sleep restraints.
-
Joe Kerwin (CAPCOM)
-
Yes, that's understandable. You can always use them if you have to. I guess it's pretty hard to get extra coveralls on, huh?
-
Jim Lovell (CDR)
-
Well, Joe, I didn't think we had any extra inflight garments aboard, but we're going to check right now.
