Jerry Carr (CAPCOM)

Apollo 8, Houston. The CM vector is in; working on the LM now. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. We'd like a cryo fan cycle when you can. Over.

Frank Borman (CDR)

Roger. We're starting that now.

Jerry Carr (CAPCOM)

Apollo 8, Houston. The LM vector is loaded. Target load going in now.

Jerry Carr (CAPCOM)

Apollo 8, Houston. The update is complete. You can have the computer, TLM to BLOCK. Be advised the erasable dump checks out okay.

Jim Lovell (CMP)

Roger. Thank you. We have the computer; we're in BLOCK.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. We'd like to make at this time a down-voice backup COMM check. Set the S-band AUX tape to DOWN-VOICE BACKUP, TLM inputs PCM, LOW. Over.

Bill Anders (LMP)

Roger, Houston. And we'd like to have a check of our DSE on low bit rate for voicing.

Jerry Carr (CAPCOM)

Roger. Understand you want the DSE check on low bit rate for voice.

Frank Borman (CDR)

That's affirmative, and we'll give it about 10 minutes now or about 5 minutes, then you can check it out.

Jim Lovell (CMP)

As a matter of interest, we have as yet to see the moon.

Jerry Carr (CAPCOM)

Apollo 8, Houston. What else are you seeing?

Bill Anders (LMP)

Nothing. It's like being on the inside of a submarine.

Frank Borman (CDR)

Houston, we just did a PROGRAM 21, and we show a pericynthian of plus 74.9 miles on the state vector you just uploaded.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Reading your down-voice backup loud and clear. Request you keep those switches where they are for the remainder of the pass. Over.

Frank Borman (CDR)

Roger. And we're rewinding the tape recorder for a dump for a DSE voice check.

Frank Borman (CDR)

It's rewound; are you ready to dump?

Frank Borman (CDR)

We'd like to go to S-band AUX tape briefly so you can dump the tape while we're on the high gain. We've only got about 30 seconds worth.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Roger. We'll do that from the ground. Over.

Frank Borman (CDR)

Roger. Switch configuration is down-voice backup and stop. You got it.

Jerry Carr (CAPCOM)

Roger. We will dump it.

Frank Borman (CDR)

You won't need to dump more than a minute's worth.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Frank Borman (CDR)

Roger. This is Apollo 8.

Jerry Carr (CAPCOM)

Roger. That pericynthian you read out is for ignition. We read that as 75 miles; your true pericynthian is 64 miles at 69:10:35. Over.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston with an addition to your TEI 1 maneuver PAD. Over.

Jerry Carr (CAPCOM)

Roger. Under remarks, add the following: “requires minus MA procedure”. Over.

Frank Borman (CDR)

Requires minus MA procedure.
