Jerry Carr (CAPCOM): Apollo 8, Houston, We'd like to go back to high bit rate in order to get this P23 data recorded. Over.
00 17 52 36
Bill Anders (LMP): Our checklist says low bit rate, Houston. If you want high, you can have it.
00 17 52 40
Jerry Carr (CAPCOM): Roger. We're going high bit rate.
00 17 52 46
Bill Anders (LMP): Okay.

Jerry Carr (CAPCOM): Apollo 8, Houston.
00 18 09 20
Frank Borman (CDR): Go ahead, Houston.
00 18 09 22
Jerry Carr (CAPCOM): Apollo 8, Houston. Do you want us to turn off your DSE for you? It's probably about half full. We're getting good high bit rate down.
00 18 09 31
Frank Borman (CDR): Do you want to get the rest of this data?
00 18 09 34
Jerry Carr (CAPCOM): We're getting good high bit rate down.
00 18 09 39
Frank Borman (CDR): Roger. Go ahead.
00 18 09 41
Jerry Carr (CAPCOM): Okay. And, also, we're—your state vector is now based on about 5 hours of tracking. We have you on a pericynthian of 69.7 miles with a free return. Your entry flight path angle looks like about minus 14. You will need only a few feet per second to get you back on a nominal entry angle.
00 18 10 43
Jerry Carr (CAPCOM): Apollo 8, Houston. Did you get the words on the state vector?
00 18 11 14
Frank Borman (CDR): Houston, did you read? Apollo 8. We got a lot of noise.
00 18 11 20
Jerry Carr (CAPCOM): Apollo 8, Houston. Go ahead.
00 18 11 40
Frank Borman (CDR): Houston, Apollo 8.
00 18 11 43
Jerry Carr (CAPCOM): Apollo 8, Houston. Go.
00 18 11 54
Jerry Carr (CAPCOM): Apollo 8, this is Houston reading you fairly weak. I'll repeat the state vector information. Your state vector is now based on 5 hours, more than 5 hours of tracking. We show you on a pericynthian of 69.7 miles with a free return with entry path flight angle of minus 14 degrees. Will only need a few feet per second at the lunar distance to get you back on a nominal entry angle. Over.

Frank Borman (CDR): Roger. Copy.

Jerry Carr (CAPCOM): Roger.
00 18 22 15
Frank Borman (CDR): Houston, Apollo 8.
00 18 22 18
Jerry Carr (CAPCOM): Apollo 8, Houston. Go. Reading you weak, but clear.
00 18 22 22
Frank Borman (CDR): Roger. Our sighting schedule is complete, and I'm maneuvering to PTC attitude.
00 18 22 28
Jerry Carr (CAPCOM): Roger. Copy.
00 18 42 03
Frank Borman (CDR): Houston, Apollo 8. Over.
00 18 42 05
Jerry Carr (CAPCOM): Apollo 8, Houston. Go.
00 18 42 09
Frank Borman (CDR): Roger. I'm at the PTC maneuver now. Like a distance status from you—how the battery looks and how the fuel cells look and et cetera. Over.
00 18 42 23
Jerry Carr (CAPCOM): Roger.
00 18 43 21
Jerry Carr (CAPCOM): Apollo 8, Houston.
00 18 43 24
Bill Anders (LMP): Go ahead.
00 18 43 26
Jerry Carr (CAPCOM): Apollo 8, this is Houston. We figure battery B will be charged in about 2 to 3 hours. All your systems look GO; your RCS usage so far is about 60 pounds, six-zero pounds over nominal. Over.
00 18 43 45
Bill Anders (LMP): Roger. How about fuel cell 2; is that looking all right now?
00 18 43 50
Jerry Carr (CAPCOM): Roger. Fuel cells are all looking good.
00 18 43 54
Bill Anders (LMP): Okay. We're going to have two of us hit the hay now and one man minding the store so you might have everybody keep an extra sharp eye on …
00 18 44 09
Jerry Carr (CAPCOM): Roger, Bill. You think you're going to be able to sleep okay?
00 18 44 12
Bill Anders (LMP): Yes. I think we kinda warmed up to a good sleep here by now.
00 18 44 20
Jim Lovell (CMP): Houston. Apollo 8.
00 18 44 22
Jerry Carr (CAPCOM): Go ahead.
00 18 44 24
Jim Lovell (CMP): Onboard navigation indicates a pericynthian altitude of 38.4 miles.
00 18 44 32
Jerry Carr (CAPCOM): Understand; 38.4 miles.
00 18 44 38
Jim Lovell (CMP): That's affirmative. It's on the DSKY right now, if you're reading it.
00 18 44 42
Jerry Carr (CAPCOM): Roger. Copy.
00 18 47 37
Jerry Carr (CAPCOM): Apollo 8, Houston.
00 18 47 42
Bill Anders (LMP): Go ahead, Houston.
00 18 47 43
Jerry Carr (CAPCOM): Apollo 8, Houston. Be advised your downlink now is getting very noisy.
00 18 49 52
Jerry Carr (CAPCOM): Apollo 8, this is Houston with some comments on navigation.
00 18 49 59
Frank Borman (CDR): Go ahead, Houston.
00 18 50 02
Jerry Carr (CAPCOM): Good morning, Frank. Apollo 8, this is Houston. We're wondering about your GDC backup align; we'd like your opinion on the possibility of doing this align using Sirius and Rigel rather than Navi, as it's in the north set at this time. Over.
00 18 50 31
Jim Lovell (CMP): Stand by one.
00 18 50 33
Jerry Carr (CAPCOM): Roger.
00 18 51 06
Jim Lovell (CMP): Houston, this is Apollo 8. We concur. Sirius and Rigel would be two stars that would be much better than Navi and Polaris. However, I did Cassiopeia after I became adapted, but I'm afraid that the time required to do that type of alignment would be extensive if we ever had to go to that alignment.
