Spacelog Apollo 8

Roger. Reading on P21 at 269 10 indicates a parallel of about 67.4 miles. I guess we can carry her.

You guys are getting pretty good.

That's a lot better than our first answer.

Houston, Apollo 8.

Go ahead, Apollo 8.

Roger. I'd like to ask a question about this TLI plus 11 maneuver that we copied. In the remarks, you put P37, DELTA-V 7900. Is this the DELTA-V that we would use with P37?

Okay. That's the option that you use with minimum time.

Roger. What I'd like to do is check on our P37 with your TLI maneuver update.

Okay, Apollo 8. We'd like to make sure that we don't have a misunderstanding that this 7900 feet per second is the DELTA-V. It's not associated with the high speed per feet work around procedure. This is just a standard P37 DELTA-V.

Roger. But was that the DELTA-V that you used to give us the TLI plus 11? Okay.

Okay. That's not the one that the maneuver PAD was based on. That's the number you put in for the minimum time.

Roger. Understand.

Okay. Sounds like a good idea if you want to go ahead and check out the 37. And we're standing by to work on COMM as soon as that high gain is available.

Okay. Houston, you got the high gain.

Houston, do you read? Apollo 8. Over.

Apollo 8, Houston.

Roger. High gain yours.

Okay. And if you're ready, we are. We'll go right ahead with our COMM checks.

Go ahead.

We're starting in now on our fourth test. Like for you to put your TELEMETRY INPUT switch to PCM HIGH.

It's in HIGH.

Okay. And now we're going to switch uplink to the upvoice backup for about 2 minutes, and it may take a couple of seconds when you hear the upvoice lost. So you can place your up-telemetry switch to upvoice backup, and in the event that all of this doesn't work out too well, I'm reading 12:47 on my clock now, and let's meet back in our present configuration no later than 12:50.

Roger. On upvoice backup.

Okay. Thank you.

Apollo 8, Houston.

Roger, Houston. Read you loud and clear.

That's pretty good. That's upvoice backup, and will you confirm that you're in NARROW BEAM on high gain?

Roger. NARROW BEAM.

Okay. Thank you. We're going to continue tracking and watching high-gain antenna for a couple of minutes. Then I'll give you a call when we're ready to go back.

Roger.

Apollo 8, Houston. We have completed this test. We'll be switching back to full uplink. When you hear the noise associated with the loss of modulation, you can go back from the up-telemetry switch to DATA.

Thank you.

All the way.

Okay. Loud and clear.

How's everything looking down there?

Real fine. We've just got one to go here if you'll put your telemetry input PCM switch to LOW.

Roger. Go in LOW.

Okay. We'll be in that configuration for about 2 minutes, and then we'll be completed with the COMM test.

Roger.

I have some service module RCS quantities if you would like to take them sometime and check them against your onboard calculations.

Stand by.

Roger. Ready to copy. Could you give quad A, B, C, and D in that order?

Okay. Will do. And I'll give you weights in pounds and percentages. Quad A 231 for 76 percent.

Roger. Stand by. What time is that for?

Oh, 12 plus 15.

Okay. Got it.

Okay. Quad Bravo 251, 82 percent. Quad Charlie 240, 79 percent.

Slow down.

Quad Delta 245, 81 percent. P and C advises that these numbers are still good even though it is a 12:15 time. And we are completed with the COMM test. You can take your high-gain antenna and go back to MEDIUM.

Roger. MEDIUM.

Apollo 8, we would like to dump your tape again, if you are not using it. And the reason we want to do this is we have some—we didn't completely get dumped before the burn. We would like to get that and get the rest of the burn data. There is no hurry on it. We can do it whenever it is convenient for you.

You got it.

Okay. Thank you.

Apollo 8, Houston. Do you call?

Negative, negative. Negative, Houston.

Okay. Thank you. Say, we're curious about what you did with your Mae West?

We thought we might bleed the CO₂ out into the vacuum connector here in our next water dump. We forgot it the last time. Did you copy?

Roger, Doesn't seem like there is any problem with going ahead and dumping it in the cockpit if you like.

It is CO₂, isn't it?

That's affirm.

Apollo 8, Houston. We asked it again, and it looks like no problems at all with going ahead and bleeding it down in the cockpit. And then if you need it again on entry or after entry, well, we can blow it up with oral tube.
