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.

Bill Anders (LMP)

Our checklist says low bit rate, Houston. If you want high, you can have it.

Jerry Carr (CAPCOM)

Roger. We're going high bit rate.

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.

Frank Borman (CDR)

Do you want to get the rest of this data?

Jerry Carr (CAPCOM)

We're getting good high bit rate down.

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.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Did you get the words on the state vector?

Frank Borman (CDR)

Houston, did you read? Apollo 8. We got a lot of noise.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go ahead.

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.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go. Reading you weak, but clear.

Frank Borman (CDR)

Roger. Our sighting schedule is complete, and I'm maneuvering to PTC attitude.

Frank Borman (CDR)

Houston, Apollo 8. Over.

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.

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.

Bill Anders (LMP)

Roger. How about fuel cell 2; is that looking all right now?

Jerry Carr (CAPCOM)

Roger. Fuel cells are all looking good.

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 …

Jerry Carr (CAPCOM)

Roger, Bill. You think you're going to be able to sleep okay?

Bill Anders (LMP)

Yes. I think we kinda warmed up to a good sleep here by now.

Jim Lovell (CMP)

Onboard navigation indicates a pericynthian altitude of 38.4 miles.

Jerry Carr (CAPCOM)

Understand; 38.4 miles.

Jim Lovell (CMP)

That's affirmative. It's on the DSKY right now, if you're reading it.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Be advised your downlink now is getting very noisy.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston with some comments on navigation.

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.

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.

Jerry Carr (CAPCOM)

Roger, Jim. We understand. We'll go ahead and work in that direction, and we'll quit bothering you. Good night.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston.

Jim Lovell (CMP)

Go ahead, Houston. Apollo 8.

Jerry Carr (CAPCOM)

Apollo 8, Houston. At 19 GET, we're due for another cycle through on the cryo fans. Over.

Jerry Carr (CAPCOM)

Roger. Give us a call when you're complete.

Frank Borman (CDR)

Give me a call when it is time to quit charging the battery, will you? I can't watch it very well over there.

Frank Borman (CDR)

And I'm starting with the fans now.

Frank Borman (CDR)

Okay, Houston. We cycled through the fans 2 minutes each, and we'll stand by for the call for battery charges.

Jerry Carr (CAPCOM)

Apollo 8, Houston. The battery charge will be complete around 21 hours.

Frank Borman (CDR)

Okay. Just give me a call.

Jerry Carr (CAPCOM)

Apollo 8, Apollo 8, Houston. Go.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go ahead.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Go ahead.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go ahead.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go ahead.

Frank Borman (CDR)

Roger, Houston. Crew status report here. We're behind on water and food, and we don't seem to have too much of an appetite. We're trying to stay up with the water, but the food is—not that there's anything wrong with the food, but we're just not very hungry.

Jerry Carr (CAPCOM)

Roger. Understand, Frank.

Frank Borman (CDR)

The CDR got 5 hours of fitful sleep and rest, and the other two people are trying to sleep now.

Jerry Carr (CAPCOM)

Roger.

No contact for 1:24:10
Frank Borman (CDR)

Go ahead, Houston. Apollo 8.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. At 21 hours, we'd like you to terminate the battery B charge and start battery A charge and then begin an O2 purge. Over.

Frank Borman (CDR)

Roger. Understand; terminate battery B, start battery A, and an O2 purge.

Jerry Carr (CAPCOM)

Roger. O2 fuel cell purge.

Frank Borman (CDR)

Houston, Apollo 8. We are now charging battery A, and say again about the purge.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Roger. Copy your battery charge setup; now begin a fuel cell O2 purge. Over.

Frank Borman (CDR)

Fuel cell O2 purge. Roger.

Frank Borman (CDR)

Houston, the fuel cells are all purged.

Frank Borman (CDR)

How's the tracking going, Jerry?

Frank Borman (CDR)

How's the tracking looking?
