Spacelog Apollo 11

Houston, Columbia on OMNI D Delta. Over.

Columbia, Houston. Roger. Loud and clear. And if you would like to take it down, we have the latest position of Tranquility Base. Over.

Go ahead.

Roger. It's just west—at west crater, Juliett 0.5, 7.7. Over.

Understand that it is just west of the crater Juliett 0.5 and 7.7. Is that correct?

Columbia, Houston. That is correct.

Okay. Thank you, Ron.

Tranquility Base, Houston.

Go ahead.

Roger. Because of the lower load with the rendezvous radar off, we'd like to have battery 5 and 6 on the line now, 1 and 3 off. Over.

In work.

Roger. Thank you.

Columbia, Houston. You're still looking mighty fine to us.

…

Columbia is holding inertially at lift off attitude, my DAP is configured as per my procedures at a time of 124 02.

Columbia, Houston. Roger. We copy you.

I'm using B and D roll.

Roger. Columbia, was that Bravo and Delta roll? Over.

Columbia, affirmative.

Columbia and Tranquility, I'll give you a Mark at 20 minutes to go, and that's in about 20 seconds.

Stand by.

MARK.

20 minutes.

Columbia. Roger.

Tranquility Base, Houston.

Go ahead.

Roger. Just a reminder here, we want to make sure you leave the rendezvous radar circuit breakers pulled. However, we want the rendezvous radar mode switch in LGC, Just as it is on Surface 59.

Okay.

Tranquility Base, Houston.

Roger. Go ahead.

Roger. Our guidance recommendation is PGNS, and you're cleared for takeoff.

Roger. Understand. We're number 1 on the runway.

Roger.

Houston, Tranquility. We're not sure that we got number 2 tank to fire. It's still showing a high pressure.

Roger. We confirm that. Try it again.

Okay. We'll go to number 2 this time.

Roger. We concur.

Houston, looks like there's very little difference between the two.

Roger.

We've got number 2 reading 3050 and number 1 is reading—3000 and it drops down to 2990. So I'm not sure that it's really indicative that it didn't go. Over.

Roger. We copy and we agree.

Okay. I assume we're—we're GO for lift off, and we'll proceed with the ascent feed.

Roger. That's correct, and we'll go ahead and watch tank 2. If it doesn't—tank 2 doesn't decrease, we'll tell you to close the ascent feeds and open the shutoffs. Over.

Okay. Ascent feeds are open and shutoffs are closed.

Roger.

And I've got the cross feed on.
