Ronald Evans (CAPCOM)

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

Ronald Evans (CAPCOM)

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

Michael Collins (CMP)

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

Ronald Evans (CAPCOM)

Columbia, Houston. That is correct.

Ronald Evans (CAPCOM)

Tranquility Base, Houston.

Ronald Evans (CAPCOM)

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.

Ronald Evans (CAPCOM)

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

Michael Collins (CMP)

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

Ronald Evans (CAPCOM)

Columbia, Houston. Roger. We copy you.

Ronald Evans (CAPCOM)

Tranquility, Houston. Say again.

Neil Armstrong (CDR)

Houston, we were not calling.

Ronald Evans (CAPCOM)

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

Ronald Evans (CAPCOM)

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

Ronald Evans (CAPCOM)

Tranquility Base, Houston.

Ronald Evans (CAPCOM)

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.

Ronald Evans (CAPCOM)

Tranquility Base, Houston.

Ronald Evans (CAPCOM)

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

Buzz Aldrin (LMP)

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

Neil Armstrong (CDR)

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

Ronald Evans (CAPCOM)

Roger. We confirm that. Try it again.

Buzz Aldrin (LMP)

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

Buzz Aldrin (LMP)

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

Buzz Aldrin (LMP)

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.

Ronald Evans (CAPCOM)

Roger. We copy and we agree.

Buzz Aldrin (LMP)

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

Ronald Evans (CAPCOM)

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.

Buzz Aldrin (LMP)

Okay. Ascent feeds are open and shutoffs are closed.

Buzz Aldrin (LMP)

And I've got the cross feed on.
