Apollo 8, Houston. Readback is correct. Ready to copy TEI 1. Over.

Roger, Houston.

Apollo 8, this is Houston. Are you waiting for us before you start your gimbal check? Over.

We can start the gimbals check right here.

Roger. You want to copy while you're doing it or stand by on TEI 1?

Stand by for a minute.

Roger. standing by.

Apollo 8, this is Houston. Shifting command back to Honeysuckle. Over.

Apollo 8, Houston. How did that gimbal drive check go?

It went fine.

Roger, Frank. We're ready with the TEI 1 and 2 maneuver PAD's. We've also got two state vectors and a target load to uplink and load if you'll configure for it. Over.

Roger. We're trying to get the high gain now. We're maneuvering to PTC attitude.

Roger.

Go ahead with your TEI PAD's.

Copy. Looks like you left out a digit …

Apollo 8, Houston. Request you switch your OMNI. It's getting pretty garbled now.

Roger. Stand by.

Houston, this is Apollo 8. I copied. I question the latitude and the range to go. It appears that you gave me one too few digits in both cases.

Roger. I repeat, latitude plus 0920, minus 16500 12953 36175 146:32:16. Copy?

I copied.

Roger. Your GDC align is no change, ullage no change, horizon on the minus 2-degree line at ignition minus 3 minutes, assumes LOI 1. Over.

Apollo 8, this is Houston. Roger. Correct. I repeat DELTA-V_Z plus 02406. Over.

Roger. Plus 02406.

Roger.

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

Roger.

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

Roger. We're starting that now.

Roger.

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

Roger.

Apollo 8, Houston.

Go ahead, Houston.

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

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

Roger.

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.

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

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

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

Roger.

Houston, Apollo 8.

Apollo 8, Houston. Go.

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

Roger.

Apollo 8, Houston. What else are you seeing?

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

Roger.

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

Roger. Plus 74.9.

Roger.

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.

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

Roger, 8.

It's rewound; are you ready to dump?

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.

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

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

Roger. We will dump it.

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

Roger.

Apollo 8, Houston. Over.

Apollo 8, Houston.

Roger. This is Apollo 8.

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.

Roger.

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

Stand by a minute.

Go ahead.

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

Requires minus MA procedure.

Affirmative, 8.
