Spacelog Apollo 8

Go ahead, Houston.

Alright, Apollo 8. You are GO for TLI. Over.

Apollo 8, Houston. Over.

Go ahead, Houston. Apollo 8.

Roger. We will have LOS in about 30 seconds, and we'll pick you up over ARIA 1 at 02:37:30.

Houston, this is Apollo 8. How do you read?

Apollo 8, Houston. Over.

Houston, Apollo 8. I hear you garbled but fairly clear.

Apollo 8, Houston. Over.

Go ahead, Houston. Apollo 8.

Good; you're loud and clear through the Mercury, and you're looking good dawn here. Everything looks good.

Roger. Understand. Our O₂ flow is a little bit higher than I thought, but Bill says that it's just about what he expected.

Roger. Understand.

Your He flow looks good down here.

Apollo 8, Houston. You're looking good.

Roger.

Apollo 8, coming up on 20 seconds to ignition. Mark it, and you're looking very good.

Roger.

IGNITION.

Roger. IGNITION.

Apollo 8, Houston. You're looking good.

Apollo 8, Houston. Trajectory and guidance look good. Over.

Roger. Apollo 8, looks good here.

Apollo 8, Houston. We're predicting cut-off, 02:55:58, and it looks exactly nominal here.

Roger.

Apollo 8, Houston. That predicted cut-off, 02:55:52, 52, and that's exactly as it should be.

02:55:52.

Apollo 8, Houston. You are looking good here, right down the center line.

Roger. Apollo 8.

Apollo 8, Houston. You are looking good, right down the old center line.

Roger. Apollo 8.

Okay—We got SECO right on the money.

Roger. Understand; SECO.

Apollo 8, Houston. Looks like a good cut-off. Everything is looking real good down here.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Your cut-off looked very good down here. We have a whole room full of people that say you look good.

Roger. Thank you. The only situation we have here in the O₂ flow is high, O₂ flow is a bit high.

Roger. Understand; O₂ flow high.

We'll get to first status report here shortly.

Roger.

Apollo 8, Houston. Your booster configured normally, and we're not concerned with the O₂ high flow. We think it's normal.

Okay.

Houston, Apollo 8.

Roger. Go ahead.

Booster begins maneuver to SEP attitude at 03:10:55. Takes 5 minutes, so it arrives at 03:15:55, and SEP time, 03:20:55. Your SEP attitude, the gimbal angles on the PAD remain good.

Roger. I have those times. The SEP time will be 03:20:55.

Right.

Houston, Apollo 8. Over.

Apollo 8, Houston. Go ahead.

Roger. Going to start charging battery B.

Okay. Battery B.

And would you keep a special eye on the purge tank and cryo O₂ tank 1 DELTA-V for us since our flowmeter is pegged out, we got no warning on O₂ high flow.

Roger, Bill. We'll do that for you.

Okay. Maneuvers started to separation attitude.

Roger, Apollo 8.

Houston, Apollo 8. How do you read?

Yes, reading you loud and clear, Frank. Understand you've started the maneuver to SEP attitude.

Roger.

Are you reading us alright?

Loud and clear.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay. Coming up on 3 hours and 15 minutes as per flight plan; we have you GO.

Roger. GO.

You got any reading on that O₂ flow?

Stand by one.

Apollo 8, Houston.

Go ahead.

We're reading about the same as we were before on that oxygen flow. The reason it's that high is due to the cabin gas changeover. According to Apollo 7, if your data repeats theirs, you can expect it to be high for another few hours.

Roger. Thank you.

Apollo 8, Houston.

Go ahead.

You can expect that the S-IVB will be 10 degrees off in pitch at SEP attitude; however, that is GO. There is no problem involved.

Apollo 8, Houston.

Go ahead, Houston.

Roger. We have you about 30 seconds prior to separation, and everything's looking good.

Roger.

What a view!

Looks pretty good, huh?

We've SEP'd Houston. We got the IVB, right?

Roger. Apollo 8.

Houston, do you read Apollo 8?

Go ahead, Apollo 8.

Apollo 8, Houston. Over.

Apollo 8, this is Houston. Over.

This is Apollo 8 on VHF and S-band. How do you read?

Hear loud and clear, Bill. How me?

Read you loud and clear. We have SEP and looking good.
