Spacelog Apollo 8

Apollo 8, this is Houston. At 68:04, you are GO for LOI.

Okay. Apollo 8 is GO.

Apollo 8, Houston. You are riding the best one we can find around.

Say again.

You are riding the best bird we can find. Over.

Thank you.

The cryo's have been stirred, Houston.

Roger, Bill.

Apollo 8, Houston. We just saw an MC&W light.

We just tested the caution and warning.

Roger.

That's keeping alert.

Apollo 8, Houston. We're 42 minutes from LOS, and we caught another caution and warning light.

It was the high-gain antenna going out of limits.

Apollo 8, Houston. Voice quality on the DSE dump is very good. The DSE is yours. Over.

Apollo 8, Houston. COMM check.

Read you loud and clear, Houston.

Houston, Apollo 8. Over.

Apollo 8, Houston. Go.

Roger. We are ready to activate the primary water boiler.

Roger. Copy.

We got a GO?

Roger. GO.

Okay. Steam pressure going to AUTO; H₂ flow going to AUTO.

Apollo 8, Houston. We are on low bit rate. We won't see your steam pressure; your RAD OUT is 33. Over.

Roger. We're below the boiling limit, and steam pressure is steady at 0.15.

Roger.

Apollo 8, Houston. Go.

Roger. We're showing a fuel pressure of 167, in AUX of 163. Wondering, do you think there's a possibility of us having a transient caution warning trip on fuel AUX pressure at the beginning of the burn that would correct itself nominally as we had a chance to pressurize? Over.

Roger. Understand; will check. Stand by.

Roger.

Apollo 8, Houston.

Go ahead.

Apollo 8, this is Houston. We've been reading fuel 173, AUX 167, holding steady for a long period of time. We expect no caution and warning trip. Over.

Apollo 8, Houston. Nine minutes 30 seconds from LOS.

Roger. Understand.

Apollo 8, Houston.

Go ahead.

Roger. In about 10 seconds, we'll have you 19 minutes from ignition. Five, four, three, two, one -

Apollo 8, Houston. Five minutes LOS, all systems GO. Over.
