04 19 38 51
Ken Mattingly (CAPCOM): Okay. I guess we should start off with a little dialogue about sleep. How much did you have?
04 19 39 03
Bill Anders (LMP): Well, let's see; whenever it was I told you I went to bed last night till now. Just a second and let me check the flight plan.
04 19 40 48
Bill Anders (LMP): Have you got it logged in when it was I asked for that last Seconal?
04 19 40 57
Ken Mattingly (CAPCOM): Okay. I guess we can figure that out for ourselves, can't we?
04 19 41 02
Bill Anders (LMP): Yes. Why don't you let me know. I have kind of lost track of time it was when I went to bed. But it was about—I went to sleep about 15 minutes after that and woke up about 10 minutes ago. Good sleep.
04 19 41 12
Ken Mattingly (CAPCOM): Okay. So I see it is now 142 hours.
04 19 41 27
Bill Anders (LMP): What do you think I am, Rip van Winkle?
04 19 41 30
Ken Mattingly (CAPCOM): Just trying to find out how soundly you really slept. I guess you are not that sleepy.
04 19 41 36
Bill Anders (LMP): . . . but not that.
04 19 41 40
Ken Mattingly (CAPCOM): Okay. It's really about 4 hours, Bill.
04 19 41 50
Bill Anders (LMP): Okay. Good.
04 19 42 39
Ken Mattingly (CAPCOM): Apollo 8, Houston. Have you got somebody under the left couch, or could you get down to the water control panel?
04 19 42 49
Bill Anders (LMP): I can get down there. Frank hasn't quite gone to sleep yet.
04 19 42 52
Ken Mattingly (CAPCOM): Well, what we were thinking about doing was boiling a little out of the secondary evaporator to check it out, just as a component check, something we need to do; but if there's somebody down there in the way, why, we can do that some other time.
04 19 43 17
Bill Anders (LMP): Well, if it boils, we are going to know it before—it won't take long to find out it won't boil. There's not a heck of a lot we can do about it, so why don't we wait until someone else wakes up here, Frank wakes up again. How will that be?
04 19 43 27
Ken Mattingly (CAPCOM): Yes. That would be fine. There is something you can do; you can reservice it. And it is kind of a tedious process, and that's the reason why we just want to kind of keep our eyes on it so we will have some idea prior to entry if we can count on having two loops or one. Which kind of leads us into another question we are trying to pin down, two questions, in fact. Number one, we would like to verify that you do plan to use both primary and secondary boilers during the actual entry, and we are also looking for a way of checking the primary boiler to make sure it isn't dried out prior to entry. And that is turning into a little more of a challenge than you might suspect. If you have any thoughts on that subject, we can go over that.
04 19 44 21
Bill Anders (LMP): The answer to the question is yes, we do plan to use both. Before we get into the water boiler pump though, CDR would like to take a Seconal also; make sure he can get off to sleep here.
04 19 44 41
Ken Mattingly (CAPCOM): Okay. That's a GO.
04 19 44 46
Bill Anders (LMP): Okay. On the water boiler: it's interesting that I get my own—I was going to say anytime you have our mike keyed, I can hear myself talk with about a 2-second time delay. With respect to the primary and secondary boiler checks, I think that is a good idea to make sure we got them both prior to entry and have the reservicing procedures handy.
04 19 45 39
Ken Mattingly (CAPCOM): Roger, Bill. You know the secondary—well, in fact, both reservicing procedures are available in a malfunction book, and sort of the problem with checking out the primary boiler is finding a way to make it boil on the way in.

04 19 46 03
Bill Anders (LMP): Yes. Just a second, I got another little chore going here.
04 19 46 39
Bill Anders (LMP): Roger. It looks like the only way we'll be able to do it would be to shut off the radiators.
04 19 46 48
Ken Mattingly (CAPCOM): We were looking for a little more docile way to do that.
04 19 46 55
Bill Anders (LMP): Roger. That way would be agreeable to me too, a little more docile way, but they shouldn't freeze up if we did it quickly.
04 19 47 08
Ken Mattingly (CAPCOM): Roger. We are talking over several things, you know, like putting the ten-pin valve to MANUAL or partially closing it or some of these different ideas, and something you can think about while you are laying there with nothing else to do.
04 19 47 26
Bill Anders (LMP): Yes. We noticed that it had gotten warmer in the cockpit coming back than it was going out. And I remember going out when we manually positioned the ten-pin valve, but we had pretty good control over the glycol evap outlet temperature. So possibly that would be the thing to attack first rather than the radiators.
04 19 47 49
Ken Mattingly (CAPCOM): Okay. We've got the back room boys looking at it.
04 19 47 57
Bill Anders (LMP): I guess if we do pick a time, though, we ought to pick a time that if something did go haywire, we could afford to boil . . . the rest of the way in, but still leave us enough time to fix—rig up the evap service if it didn't work.
04 19 48 12
Ken Mattingly (CAPCOM): That's affirm, and we're factoring in things like trajectory considerations and all that sort of thing, too.
04 19 48 22
Bill Anders (LMP): Right. I think that the second derivative of the water boiler versus time plot will give us the optimum time to do it.
04 19 48 45
Ken Mattingly (CAPCOM): EECOM's copying that.
04 19 48 52
Ken Mattingly (CAPCOM): There's also speculation you have a chart on board that gives that information.
04 19 49 02
Bill Anders (LMP): Well, if I don't, I'm sure those guys can ship one up. They've shipped up some other pretty good ones.
04 19 49 08
Ken Mattingly (CAPCOM): It's also been suggested that if you don't have the chart it's on the tape recorder.
04 19 49 18
Bill Anders (LMP): Well, if I don't have a chart, I'll put it on the tape recorder.
04 19 49 27
Bill Anders (LMP): Okay. I think, unless you guys got some more comments along these lines, maybe we ought to give these guys a chance to get to sleep, and I'll recline here for a while. If you've got something to brief me on, well, go ahead; but I'd like to keep my answers to yes's and no's and whatever else you think you really need.
04 19 49 51
Ken Mattingly (CAPCOM): Okay. Fine, Bill, and I'll check with you like every 30 minutes, just to make sure we still have voice contact.
04 19 50 02
Bill Anders (LMP): Okay. I've got some log writing to do and whatnot. So keep an eye on the systems and the gimbal angles, and we'll be all right.
04 19 50 11
Ken Mattingly (CAPCOM): Okay.
04 19 52 17
Bill Anders (LMP): And, Ken, if your EECOM man wants to play the OMNI-switch game, we're on Dog—Bravo at this time, actually on Bravo but also configured for D's—correction, we are on D and also configured for Bravo. If you want to switch, we'll go ahead.
04 19 52 43
Ken Mattingly (CAPCOM): Okay, we'll give that a try, and we are cranking up some Background music for you.
04 19 52 55
Bill Anders (LMP): Okay. The last time they did that, it sounded like they were running at the wrong speed on the tape, but we're a little closer now. Maybe it'll be a little better.
04 19 53 02
Ken Mattingly (CAPCOM): Would you also believe Doppler shift?
04 19 53 14
Bill Anders (LMP): Might be another way to range.
04 19 53 25
Bill Anders (LMP): Probably it was Doppler shift; we're heading back out again,
04 19 53 38
Ken Mattingly (CAPCOM): Looks like we can use your humming for backup ranging in case everything else fails.
04 19 53 46
Bill Anders (LMP): Roger.
04 19 54 15
Ken Mattingly (CAPCOM): Apollo 8, Houston. You don't need to answer this transmission, but doctors observe that it looks like your—some of your sensors may be working loose, so you might just kind of push on them and see if they are in place.

Ken Mattingly (CAPCOM): Looks like it is one of your sternals, Bill.
