Spacelog Apollo 8

Good show. Thank you.

Apollo 8, Houston. We would like to get an approximate GET of your SEP maneuver to use for our ephemeris tracking data.

Roger. It was 3 hours 40 minutes zero seconds.

Good, 03:40 and a foot and a half—feet per second. Right?

Roger. About that —

Okay.

— We have the—Mike, we have the exact callout here for you and a burn status report.

Alright.

Alright, DELTA-V_X minus 00011, DELTA-V_Y plus 0002, DELTA-V_Z minus 0002, roll 0, pitch 180, yaw 0. Over.

Roger, Apollo 8.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. At your convenience, would you please go P00 and ACCEPT? We're going to update to your W matrix. And also when you get a chance, we would like to know about the SLA panels. Did they all depart? And do you have any comments about the SLA?

They all departed, and they worked fine.

Okay. Thank you.

We are in P00 and ACCEPT.

Thank you.

Houston, Apollo 8. Will you give us the information when you want us to stop the venting and so on?

Apollo 8. Houston.

Go ahead, Houston.

Roger. What is the venting information are you inquiring about: the O₂ flow high out through the waste tank or waste compartment, or are you talking about your evaporator?

Evaporator. We are configuring now to stop boiling.

Okay.

We concur in that.

Apollo 8, Houston. You can go back to BLOCK. We have gotten in the load to the W matrix update.

Roger.

Houston, Apollo 8. The back pressure valve is closed, and the water flow is OFF.

Back pressure valve closed, and water flow OFF. Thank you.

Houston, Apollo 8 here.

Apollo 8, Houston. Go ahead.

Roger. It looks like I might have to do a couple more small maneuvers to stay away from the front of this S-IVB, the way we are ending up now. Do you want me to do these with our P47 if we have to do them?

Standby one, Frank.

That's affirmative, Frank, on this P47.

Okay. And give me the time again when it starts to dump, please.

Roger. We're working on an exact GET of that, Frank.

Roger.

Apollo 8, Houston.

Go ahead.

I'd like to give you some idea about your trajectory. It looks like a midcourse correction number 1, projected out to TLI plus 6 hours, would be only 7 feet per second. So, of course, any further maneuvers you do would add to that, which is probably good.

I just want to stay from away from in front of this thing.

Roger. We concur. Looks like it is chasing you, huh?

Yes.

OMNI D.

Boy, it's starting to vent now, blowing down.
