Spacelog Apollo 8

Roger, Houston. Apollo 8.

Roger. The P23 that is coming up next—we will want to do a water dump as soon as we are through with that P23. We'll dump down to 30 percent, and this ought to be the last dump of the mission. Over.

Okay, Bill. On that water dump, we expect to have 90 percent.

Houston, Apollo 8. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Go.

Roger. We are done with the P52 and arranged for the P23. Was there any constraint you wanted, for length of time you wanted to stay in this attitude?

Negative, Bill. When you are finished with P23, we will go back into PTC.

Okay. We are going to maneuver for P23 now.

Roger. We are watching your tank pressures.

Okay. Thank you. We will do an optical first and then do the P23.

Apollo 8, Houston. We are handing over to Madrid in about 15 seconds. Over.

Roger. And good morning, Jerry, or good afternoon, or whatever it is.

Good morning, Jim. It's about 6:30 in the morning.

Apollo 8, Houston. How do you read?

Loud and clear. How us?

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Morning, Frank. Looks like we have lost the transducer on the primary radiator OUT temperature. We are showing an off scale high. The rest of the loop looks real fine, though. When you get a chance, would you take a look at it and see if you're in the same position. Over.

Which one is it?

Primary radiator OUT temperature.

Ours is showing 100 off scale high, also.

Houston, Apollo 8. Over.

Apollo 8, Houston. Go.

Apollo 8, Houston. Go.

Roger. About this RAD output temp: does your telemetry show that it happened all of a sudden?

That's affirmative, Bill.

Okay. I'm on malfunction 23, step 2. It looks to me like there is a small possibility we might be boiling, but I doubt it. So you just want to hop over to step 4 and consider that a closed case.

Apollo 8, Houston.

Go ahead, Houston.

Roger. Frank, all of your primary loop temperature readings look just fine. Your EVAP IN temperatures are normal and indicate you are getting normal mixing.

Okay. Thank you.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. For the P23 attitude that you are in right now, your quad tank temperatures are better than we expected. We're still monitoring, and it's looking good.

Thank you. After we complete this, do you want us to return to the PTC attitude? Is that correct?

That is affirmative, Frank.

Would you have someone get up the gimbal angles for us to point the X-axis at the earth at the TV time, please?

Wilco.

Also, Jerry, I would like to know our range and velocity at TV time.

Roger, Frank. You want the range and velocity at TV time.
