Spacelog Apollo 8

Apollo 8, this is Houston. If you should decide that you want to roll heads up on REV 2, one thing to remember, be sure you yaw 45 degrees right in order to maintain your high-gain antenna COMM. Over.

We will not do that; we're going to stick with the flight plan, and make the best we can here.

Roger, Frank.

As usual, in the real world, the flight plan looks a lot fuller than it did in Florida.

Apollo 8, Houston. We need an O₂ purge now.

Roger. And we're standing by for a map update.

Roger.

Houston, Apollo 8. Just for your information, after we completed P52, I acquired the earth in the sextant. Quite a sight from here.

Roger. Bet it is.

Row are the systems experts on the SPS coming, Jerry?

They are still working, Frank; another 5 or 10 minutes.

Roger.

Apollo 8, Houston. Your SPS data looks real good. It is just a matter of getting it all in from the site and getting it looked at.

Thank you.

So far, everything looks copacetic.

Apollo 8, Houston. We would like to take about 5 minutes of high bit rate. Over.

Roger. Five minutes of high bit rate coming on.

Roger.

You've got it.

Apollo 8, Houston with a map update.

Stand by one.

Go ahead with the map update.

Roger, Frank. Map update: REV 1/2, no change; the REV 2/3 follows: 73:04:57, 73:09:37, 73:19:01, 73:48:53, 74:24:23; remarks: Bravo 1 [03:02:16:24|74:16:24]. Over.

Roger. Copy.

Roger. We show you 23 minutes to LOS.

Roger. Are you going to dump the tape?

Apollo 8, this is Houston. You are GO for REV 2; all systems are GO. SPS evaluation is still underway and looking good. Over.

Understand; GO for REV 2. Thank you.

Roger, Apollo 8. We're still using the tape recorder. We will dump it in a little bit.

Apollo 8, this is Houston. The recorder is yours. You can go to low bit rate.

Apollo 8, Houston. Request BIOMED switch center.

Apollo 8, Houston. Put your TELEMETRY INPUT switch to LOW. Over.

Roger. GO in LOW.

Houston, Apollo 8. We're in the process of preparing meal 4, day—correction: day 4, meal A.

Houston, Apollo 8. Over.

Apollo 8, Houston. Go.

Are you going to be able to dump that tape prior to LOS?

Roger. Bill, they say they have already dumped the tape, and it's almost totally clean.

What does that mean?

That means you have got about 2 minutes of low bit rate on there, but the rest is clean. Over.

The high bit rate of the burn wasn't on there?

Negative. We've already dumped and got that.

Okay. Let me know when you're going to dump it next time, Jerry. I understand we are GO now on the DSE. Have you got any voice off of it?

That's affirmative. We did.
