Apollo 8, Houston. Confirm that battery B is a little bit lower, and this is attributed to the parasitic loads that are on there.
-
Bill Anders (LMP)
-
Okay. I just didn't see the same kind of drop for A. So if you think it's okay, it's fine.
-
Ken Mattingly (CAPCOM)
-
That's affirm. You don't have the same parasitic loads on that; B is actually drawing some.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. We've seen enough of the secondary evaporator. We would like for you to wait about 2 minutes between the time you go to RESET and the time you turn the pump off.
-
Ken Mattingly (CAPCOM)
-
Okay. Looking over the—our redundant component check, it appears we have not yet checked the integrity of the secondary loop radiators; and if you haven't done that, sometime we would like to open up the secondary radiators but not flow through them and just measure the accumulator pressure.
-
Frank Borman (CDR)
-
Houston, we don't show that in our pre-LOI check, but we're willing to go ahead and do it if you want to.
-
Ken Mattingly (CAPCOM)
-
Roger. We just noticed that it isn't there, and, yes, we would like to. You understand that we are not proposing that you flow, but merely we check for any pressure decay.
-
Frank Borman (CDR)
-
Okay, Houston. We're going to blow the secondary, I mean, open the secondary RAD for 30 seconds now.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. You take your tape recorder to stop, and we'll reset it then and give it back to you.
-
Ken Mattingly (CAPCOM)
-
Okay. We still need to talk about the REV 2 attitudes we're going to use here to work around the fact that you have a fogged center window. Whenever that's convenient, we'd like to go over what your thoughts are on the subject so we can make sure we can get our flight plan squared away.
-
Bill Anders (LMP)
-
My thoughts are to make—to do with the best with what we have. We are not interested in changing a lot of things right now.

Okay. The one proposal that sounds like it has some advantage to it: if we let Jim do his evaluation through the telescope, you do everything exactly the same except you turn and roll over 180 degrees so that your head's up, and let Jim do his tracking through the telescope and you'll still be a yaw right when you go to pick up your TV and that type of thing. It looks like that probably will cover everything. We can do that or we can just go as is and just have to let some of that tracking evaluation go by. Another alternate would be to have Jim look out the right-hand rendezvous window, and you may have to change your attitude in order to get the same picture there also.
-
Frank Borman (CDR)
-
I think we'll try to do that, but I don't—this is one of the things that we'll work out when we get there.
-
Ken Mattingly (CAPCOM)
-
Okay. The reason we were looking into it in the flight plan is, if you do want to try rolling over and flying heads up or something of that nature, we can help Bill get a little more out of his photography by giving him some new film settings and that type of thing. We'll have something like that available; in case you do fly heads up, why, we'll have some numbers, we can call up for film settings.
-
Frank Borman (CDR)
-
Roger. We are going to have to dump more urine here shortly. Will this bother your tracking?
-
Frank Borman (CDR)
-
Houston, just give us the time when we can start on it, and we'll hold off until you say so.
-
Ken Mattingly (CAPCOM)
-
Okay, and you can anticipate a handover between stations here on the hour, and you might get a slight glitch as we go through. I'll give you a call when we get back.
-
Ken Mattingly (CAPCOM)
-
Apollo 8, Houston. You're cleared for a dump at this time, and I understand this is the last gas station for a long time.
-
Ken Mattingly (CAPCOM)
-
That's affirm. Due to the tracking as you approach the LOI, they would like to minimize any of these type of perturbations.
-
Ken Mattingly (CAPCOM)
-
I'll bet. If you've got nothing else to do, I do have two charts in your LOI table that I need to give you some update numbers on.
-
Ken Mattingly (CAPCOM)
-
Roger.

Ken Mattingly (CAPCOM)
-
Yes, sir; I've got a couple of charts in your chart book under LOI, and I have some numbers to fill in, one of them being the chart of LOI DELTA-V magnitude versus abort DELTA-V.
-
Ken Mattingly (CAPCOM)
-
Alright. Mode 1, 5 hours, roll 1.38, pitch 7.89, yaw 357.37. Mode 1, 15 minutes, roll 180.73, pitch 29.46, yaw 1.65. Over.
-
Jim Lovell (CMP)
-
Roger. The new attitudes for the Mode 1, 5 hour Mode 15 minute are as follows: roll—for the Mode 1, 5 hour, roll 1.38, pitch 7.89, yaw 357.37; Mode 1, 15 minute, roll 180.73, pitch 29.46, yaw 1.65.
-
Ken Mattingly (CAPCOM)
-
Okay. That is correct. Now I also have to give you a couple of points to plot on that curve. The present curve you have drawn is based on a 60-mile perigee or perilune, and you right now have a 62-mile pericynthian; and the reason that your target is for 62 miles is to pass over the landing site, so I have five sets of coordinates for you to copy.
-
Ken Mattingly (CAPCOM)
-
Okay. We'll go in on the LOI DELTA-V magnitude 1600, abort DELTA-V 2450, two-four-five-zero.
-
Jim Lovell (CMP)
-
Okay. LOI DELTA-V magnitude 1600, abort DELTA-V 2450. Stand by just one. I have it; continue.
-
Ken Mattingly (CAPCOM)
-
Alright. The last one is LOI DELTA-V 2990, abort DELTA-V 5114. That is almost directly into the end of the present curve, 5114.
-
Ken Mattingly (CAPCOM)
-
Alright. And on the next one, you should have a chart (number 10), and we have three numbers to go in there for a Mode 3 gimbal angle.
-
Frank Borman (CDR)
-
Houston, could you give us some gimbal angles to point at the moon? I never have seen it the whole trip, and I'm wondering which way it is from us now.
-
Ken Mattingly (CAPCOM)
-
We are getting ready to give you a rundown on your systems. We're going over all the final steps, and we will tell you what we see in the way of trajectory and systems information. And once again, Dr. Joe Kerwin has brought over all the latest news, and we can read that up to you a little bit at a time if you aren't going to sleep.
-
Ken Mattingly (CAPCOM)
-
Okay. Here is one: the previously scheduled 72-hour cease fire by the Viet Cong went into effect today, 17 hours before the 24 hour allied truce was to begin.
-
Ken Mattingly (CAPCOM)
-
The gist of it was that the VC went into a cease fire earlier than the truce that we had planned on, as a Christmas holiday type.
