Ken Mattingly (CAPCOM): Roger. We'll keep our eye on it. It sounds good, though.
00 07 08 46
Jim Lovell (CMP): Okay. Houston, Apollo 8. We've initiated the PTC.
00 07 08 51
Ken Mattingly (CAPCOM): Roger.
00 07 09 32
Ken Mattingly (CAPCOM): Okay. Apollo 8, you can terminate the fans in the hydrogen, and we're ready to start on the oxygen tanks.
00 07 09 41
Jim Lovell (CMP): Okay. Stand by.
00 07 11 59
Ken Mattingly (CAPCOM): Apollo 8, we are through with the dump; you can have the tape recorder back.
00 07 12 02
Jim Lovell (CMP): Roger. Thank you.
00 07 15 10
Ken Mattingly (CAPCOM): Apollo 8, Houston. We are ready to go to the second O₂ tank.
00 07 15 15
Jim Lovell (CMP): Okay.
00 07 15 19
Ken Mattingly (CAPCOM): And for your information, it's Cleveland 24 to 10, and what we plan to do —
00 07 15 27
Jim Lovell (CMP): Say again.
00 07 15 30
Ken Mattingly (CAPCOM): That's Cleveland 24 to 10, not over yet.
00 07 15 42
Frank Borman (CDR): Thank you.
00 07 20 49
Ken Mattingly (CAPCOM): Okay, Apollo 8. Looks like you can terminate your cryo fans now, and we're going to leave you alone for a while and let you get caught up. Things we have onboard, the high-gain antenna check, COMM mode check that you have listed at 7 hours, we'll put off and do whenever you are ready for it. So that's at your convenience. During the high-gain dump that we performed using a wide band, we were still getting real good data at 36K, which is a little bit further than circuit margins that were predicted for you. And we've got our SPS burn coming up somewhere around 11 hours, and we'll give you more information on that later.
00 07 21 31
Bill Anders (LMP): Roger. We're doing the PROGRAM 21 now, determining ground track for LOI that we did not make at 5 hours.
00 07 21 44
Ken Mattingly (CAPCOM): Roger. Thank you.
00 07 27 20
Frank Borman (CDR): Houston, Apollo 8.
00 07 27 21
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
00 07 27 22
Frank Borman (CDR): Okay. We just broke lock on S-band high-gain. We're on OMNI B now.
00 07 27 29
Ken Mattingly (CAPCOM): Roger. OMNI B.
00 07 27 36
Ken Mattingly (CAPCOM): Apollo 8, Is that Bravo or Delta?
00 07 27 40
Frank Borman (CDR): Dog, Delta.
00 07 27 41
Ken Mattingly (CAPCOM): Roger.
00 07 27 43
Frank Borman (CDR): We can't get the PROGRAM 21 to integrate up to LOI; just stalled out around 69 hours and 2 minutes.
00 07 28 02
Ken Mattingly (CAPCOM): Roger. They are watching it.
00 07 28 35
Frank Borman (CDR): Houston, Apollo 8.
00 07 28 38
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
00 07 28 41
Frank Borman (CDR): Roger. Do you want us to stop the integration via VERB 96? Over.
00 07 28 54
Ken Mattingly (CAPCOM): That is affirmative; VERB 96.
00 07 28 57
Frank Borman (CDR): Roger. Will do.
00 07 56 51
Frank Borman (CDR): Houston, this is Apollo 8.
00 07 56 54
Ken Mattingly (CAPCOM): Apollo 8, Houston.
00 07 56 55
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
00 07 56 58
Frank Borman (CDR): Roger. Do you want us to hold off on this P52 realignment, also?
00 07 57 04
Unidentified crew member: Yes, that is affirmative, CAP COM. We want to do that a couple of hours when it is related to the maneuver, midcourse.

00 07 57 10
Ken Mattingly (CAPCOM): That is affirmative, Apollo 8. Let's time the maneuver and we will hold off and do that all in normal premaneuver sequence. And—We have got a score here—in the fourth quarter, 31 to 13. And I've got some words on your P21 discrepancy any time you are interested. And I'd like to confirm —
00 07 57 30
Frank Borman (CDR): Go ahead.
00 07 57 33
Ken Mattingly (CAPCOM): Okay. Before I get off on that one, I'd like to confirm that you used the VERB 37 procedure to go to P00.
00 07 57 41
Frank Borman (CDR): Roger.
00 07 57 43
Ken Mattingly (CAPCOM): Okay. On P21, the thinking runs that you had a slight error in your state vector at the time you started, and when that was integrated out, it intercepted the lunar surface where it locked up and this is contained in a fairly recent program note.
00 07 58 06
Frank Borman (CDR): Okay. Now, we've closed the—the waste vent, so we should see this O₂ come down now.
00 07 58 15
Ken Mattingly (CAPCOM): Okay. Understand you closed the waste vent, and how about the lithium change? Have you done that one?
00 07 58 23
Frank Borman (CDR): Roger. That's done.
00 07 58 24
Ken Mattingly (CAPCOM): Okay. Thank you.
00 07 58 30
Milt Windler (FLIGHT): EECOM, FLIGHT. Did you copy that?
00 07 58 33
Jim Lovell (CMP): This conference communication is great. We won't have to have any debriefing.
00 07 58 37
Ken Mattingly (CAPCOM): (Laughter) That's pretty outstanding.
00 07 58 38
CommTech: Right.
00 07 58 43
Ken Mattingly (CAPCOM): Did you copy that?
00 08 13 39
Frank Borman (CDR): Houston, Apollo 8.
00 08 13 42
Ken Mattingly (CAPCOM): Go ahead, Apollo 8.
00 08 13 44
Frank Borman (CDR): Roger. With the delay in burn, do you mind if we have a urine dump the—before the burn? Will that foul your tracking up?
00 08 13 52
Ken Mattingly (CAPCOM): Okay. Stand by. Let me run that one by.
00 08 14 53
Ken Mattingly (CAPCOM): Apollo 8, Houston. We don't have any objections to going ahead with the urine dump now. And for your information, the waste water dump—our schedule, we plan to put it off until about 11:30, and this will get you up to approximately 90 percent in your waste tank. It's a little higher than normal, but we wanted to put this off until after the burn was completed; and some of the other things that we've got coming up, about 9 hours you have oxygen fuel cell purge; and we've already mentioned the deletion of the star landmark sightings. From 10 to 11 we have put aside for the burn preparations. And a final score is 31 to 20.
00 08 15 40
Frank Borman (CDR): Cleveland won over Dallas, huh?
00 08 15 43
Ken Mattingly (CAPCOM): How about that?
00 08 15 49
Frank Borman (CDR): Houston, how do the circuit margins on the S-band look as compared to your preflight calculations?
00 08 16 35
Ken Mattingly (CAPCOM): Okay, Apollo 8. It's a little bit early to give you any real numbers on your COMM performance. Looks like it's working as good as predicted, and everything else seems to be doing better, so this may be doing better, too, after we have done our next COMM checks some of these other things will have a better hack on; I can give you a quantitative answer to your question.
00 08 16 56
Frank Borman (CDR): Roger.

00 08 24 23
Bill Anders (LMP): Houston, Apollo 8. How do you read?
00 08 24 26
Ken Mattingly (CAPCOM): Loud and clear, Apollo 8.
00 08 24 29
Bill Anders (LMP): Roger. Sure got a nice view of the earth from here. We can see Baja California and about where San Diego ought to be.
00 08 24 40
Ken Mattingly (CAPCOM): Very good.
00 08 24 44
Bill Anders (LMP): I can't see my dad's flagpole out there today, though.
00 08 24 48
Ken Mattingly (CAPCOM): We'll tell the doctors about that.
00 08 48 40
Ken Mattingly (CAPCOM): Apollo 8, Houston.
00 08 48 43
Frank Borman (CDR): Go ahead, Houston.
00 08 48 45
Ken Mattingly (CAPCOM): Okay. We dropped off of high gain on the OMNI there for a bit and went to a low bit rate, and we're getting ready to command you back to a high bit rate. Do you want us to keep you posted every time we change tape speeds?
00 08 49 05
Frank Borman (CDR): We're not recording now anyway, Houston.
00 08 49 08
Ken Mattingly (CAPCOM): Roger. Understand; but when we go to high bit rate, do you want to be kept informed every time we transfer? We hadn't planned on it.
00 08 49 20
Jim Lovell (CMP): If we think it we need the recorder, we'll ask you on that deal.
00 08 49 24
Ken Mattingly (CAPCOM): Okay.
00 09 09 34
Frank Borman (CDR): Apollo 8.
00 09 09 37
Ken Mattingly (CAPCOM): Go ahead.
00 09 09 40
Frank Borman (CDR): Roger. How does your tracking look on us?
00 09 09 44
Milt Windler (FLIGHT): Fido, FLIGHT.
00 09 10 13
Ken Mattingly (CAPCOM): Apollo 8, tracking still in progress and a little too soon to give you a firm answer on the results, but everything looks nominal so far.
00 09 10 26
Bill Anders (LMP): Is it working okay?
00 09 10 28
Ken Mattingly (CAPCOM): Seems to be.
00 09 12 05
Ken Mattingly (CAPCOM): Apollo 8.
00 09 12 07
Bill Anders (LMP): Go ahead.
00 09 12 09
Ken Mattingly (CAPCOM): Okay. Sometime when it's convenient for you now, I would like to see an oxygen fuel cell purge. And do you have any estimate on when you might be getting around to this COMM test?
00 09 12 24
Bill Anders (LMP): Right now we're right in the middle of trying to get something to eat, Ken. We can—I guess we can do the fuel cell purge.
00 09 12 36
Ken Mattingly (CAPCOM): Apollo 8, there's no rush. Just didn't know what you were doing at the time and—Give us a call when you have a free moment; we'll pick up.
00 09 12 50
Bill Anders (LMP): We can start the O₂ purge now, if you wish.
00 09 12 57
Ken Mattingly (CAPCOM): Okay. That'd be fine, and I'll keep track of the time for you.
00 09 13 00
Bill Anders (LMP): Okay. That'd be good. Now I'll turn on O₂ now on fuel cell 1.
00 09 13 05
Ken Mattingly (CAPCOM): Okay. Thank you.
00 09 15 41
Ken Mattingly (CAPCOM): Apollo 8, Houston. That's about 2 minutes on your first fuel cell.
00 09 15 47
Frank Borman (CDR): Roger. It's up, and number 2 is on now.
00 09 15 50
Ken Mattingly (CAPCOM): Roger.
00 09 17 31
Jim Lovell (CMP): Houston, Apollo 8.
00 09 17 33
Ken Mattingly (CAPCOM): Houston. Go ahead.
00 09 17 35
Jim Lovell (CMP): While I'm waiting for my turn at the water gun, I might give some comments on the optics. There seems to be quite a band of light that goes all way across the scanning telescope anywhere in the vicinity of the sun. Just a little while ago we were in the position where I could pick up the moon in the scanning telescope. And then I looked at it in the sextant and the sky—the space around the moon was a very light blue, just about as light blue as we have it back on earth. And it's not black—that sun angle with the moon.
00 09 18 20
Ken Mattingly (CAPCOM): Understand. This light blue was—showed up in the sextant.
00 09 18 25
Jim Lovell (CMP): That's affirmative. I maneuvered the optics so I could pick up the moon in the sextant, and the—the space around the moon is light blue.
00 09 18 37
Ken Mattingly (CAPCOM): Roger. Can you make any kind of estimate about the proportion of the radius, how far out that seems to extend?
00 09 18 46
Jim Lovell (CMP): Well, it extends the full length of the sextant. Actually, I could see us coming as we moved across, because the band of light in the scanning telescope cut across where the moon was, and it moved in this area. I believe it's caused by the refractional light inside the optics themselves.
00 09 19 05
Ken Mattingly (CAPCOM): Roger.
00 09 19 09
Jim Lovell (CMP): Also, I've been occasionally looking out to see if I could see stars at various sun angles, and at this particular altitude, it's very difficult. In the scanning telescope the sun is very bright and the earth is very bright, And if I looked at the earth and try to look for stars, I lose my dark adaptation very quickly.
