Michael Collins (CMP)

Houston, Columbia. My rendezvous radar transponder is operating.

Ronald Evans (CAPCOM)

Spacecraft calling Houston? Say again.

Michael Collins (CMP)

This is Columbia saying the rendezvous radar transponder is operating.

Ronald Evans (CAPCOM)

Tranquility, Houston. Request rendezvous radar breakers in about now.

Ronald Evans (CAPCOM)

Columbia, Houston. Request OMNI D—OMNI Delta.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. Request you go ahead and start the warmup on the rendezvous radar.

Neil Armstrong (CDR)

Houston, you copying NOUN 93?

Ronald Evans (CAPCOM)

Tranquility, affirmative. Go.

Neil Armstrong (CDR)

Roger. We're going to a torque.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. Columbia will be overhead at 122 plus 22 plus 51. His LOS will be 29 35. Over.

Neil Armstrong (CDR)

Houston, we'd like to check this on the tape meter against the AGS. We'll go back to altitude—altitude rates as soon as the rate starts to build up. Over.

Ronald Evans (CAPCOM)

Tranquility, Houston. Roger.

Neil Armstrong (CDR)

On second thought, since that will peg the range rate, I guess maybe we'd better not do that. And for this range that the AGS are showing now, 425 miles with a signal strength of 2.2. It looks like we ought to proceed on this. Over.

Ronald Evans (CAPCOM)

Roger. Stand by one. Tranquility, affirmative. Proceed.

Buzz Aldrin (LMP)

Are you getting the information on the downlink now?

Ronald Evans (CAPCOM)

Tranquility, affirmative, and we're saving it. We've got 4 so far, and it's looking good.

Neil Armstrong (CDR)

Okay. What do you people think about calling up a VERB 83?

Ronald Evans (CAPCOM)

Tranquility, Houston. Stand by on that now. We're getting the data now. We're checking on the VERB 83.

Buzz Aldrin (LMP)

And we expect that we may lose lock when it passes overhead because of the MAX rate that the radar has.

Ronald Evans (CAPCOM)

Tranquility, Houston. Negative on VERB 83.

Ronald Evans (CAPCOM)

Tranquility, Houston. Go.

Michael Collins (CMP)

They've just lost lock, Ron.

Ronald Evans (CAPCOM)

Roger. We had about 20 some points before you did that. And for your information, the reason the AGS is a little different there—The reason the AGS is a little different is because the K factor is a little bit wrong.

Buzz Aldrin (LMP)

Has he already gone? Over. Okay. Okay. Has he already gone overhead, or do you want us to try and get in lock on again?

Ronald Evans (CAPCOM)

Tranquility, affirmative. Try to lock on again, and you'll lose him at about 29 minutes and 35 seconds.

Buzz Aldrin (LMP)

Okay. Do you have a real quick procedure how to do that?

Ronald Evans (CAPCOM)

Columbia, Houston. Say again about your NOUN 49.

Michael Collins (CMP)

I say I got five good marks. You got NOUN 49. When you get everything you need off the downlink, let me know.

Ronald Evans (CAPCOM)

Columbia, Houston. Stand by one.

Neil Armstrong (CDR)

Ron, did you say on the 526 alarm to proceed or do a VERB 32?

Ronald Evans (CAPCOM)

Roger. It's just that radar thinks the range is greater than 400 miles now.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. Recommend you terminate P22. Over.

Ronald Evans (CAPCOM)

And, Columbia, Houston. Same for you. You can terminate P22.

Michael Collins (CMP)

I have. I'm running fast.

Michael Collins (CMP)

I'm staying in P22 here a second just to record the NOUN 89 and then over VERB 34.

Ronald Evans (CAPCOM)

Columbia, Houston. Roger. We copy, and that's good.

Ronald Evans (CAPCOM)

Roger. Request S BAND FUNCTION switch to RANGE. We're going to do some ranging on you. Also, I have an updated AGS K factor when you are ready to copy. Over.

Neil Armstrong (CDR)

Roger. Go ahead with the K factor.

Ronald Evans (CAPCOM)

Roger. 119 plus 59 plus 59.92. Over.

Neil Armstrong (CDR)

Roger. A little closer this time.

Ronald Evans (CAPCOM)

Tranquility, Houston. Readback correct.

Neil Armstrong (CDR)

Houston, Tranquility. I see what you mean now about the K factor.

Michael Collins (CMP)

This is Columbia. Go ahead. And I'd like to know about this P52 coming up. Is that the one I just completed or do you want a pair of them back to back?

Ronald Evans (CAPCOM)

Columbia, Houston. You do not need to do another P52 unless you want to. Break. And also, Columbia, when you get a chance, request BATT C and the PYRO readouts. Over.

Michael Collins (CMP)

BATT C says 37 volts even. PYRO A, 37. PYRO B, 37.

Ronald Evans (CAPCOM)

Columbia, Houston. Roger. We copy. Thank you.

Michael Collins (CMP)

BATT bus B is 37. BATT bus A is 36, or I'd think the gauge is stuck.

Ronald Evans (CAPCOM)

Roger. And you're looking good to us—to us, Columbia.

Michael Collins (CMP)

Yes sir. Keep it that way.

Michael Collins (CMP)

Columbia is coming up on a VERB 45 ENTER to reset the surface flag.

Ronald Evans (CAPCOM)

Columbia, Houston. Negative. Stand by on the VERB 45.

Michael Collins (CMP)

And a crew status report from Columbia. I figure I got about 5 hours' good sleep, although you guys probably know better than I do.

Ronald Evans (CAPCOM)

Columbia. Roger. We copy.

Ronald Evans (CAPCOM)

Columbia, Houston. We've got a couple more vectors to send up to you. They'll be coming up shortly and then you can do the VERB 45 after you get those in. Over.

Michael Collins (CMP)

Okay. That's fine. Just wanted to make sure that we're both in SYNC on the order.

Ronald Evans (CAPCOM)

Roger.

Ronald Evans (CAPCOM)

Columbia and Tranquility Base, this is Houston. In case you haven't noticed, the MSFN relay is not activated, so I can go ahead and relay anything if you want to talk directly.

Neil Armstrong (CDR)

Houston, Tranquility. Be advised we've got —

Neil Armstrong (CDR)

Coming … on schedule — showing red right now. We just put a VERB 77 in. I believe that there's … let me check here.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. We've got a lot of static down here. Could you say again?

Neil Armstrong (CDR)

Roger. We have four out of eight circuit breaker talkbacks indicating red. We still have the circuit breakers out as of right now. I believe at this moment we have just entered VERB 77 on tape 3052 and are ready to proceed with the hot fire. Is it normal to have these four red flags? Over.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. We think that's okay. Go ahead and reset them and press on with the hot fire. Over.

Ronald Evans (CAPCOM)

Columbia, Columbia, Houston. Request P00 and ACCEPT, and we'll send some state vectors up to you.

Michael Collins (CMP)

Here we going P00 and ACCEPT.

Neil Armstrong (CDR)

Houston, Tranquility. I used Capella in the last sighting, and it's a good ways near the edge. A good ways away from the center of detent 4. I'm wondering if it would pay any to use Alpheratz, star number 1. It might be a little closer. However, it would delay things a little, since I'd have to designate the radar out of the way. Over.

Ronald Evans (CAPCOM)

Tranquility. Roger. We copy. Stand by 1. And, break, break, Columbia. We're having a little trouble getting the stuff in there. Request high gain, pitch minus 20, yaw plus 150. Over.

Ronald Evans (CAPCOM)

And, Tranquility, Houston. We'd prefer to save the time; press on with Capella. Over.

Ronald Evans (CAPCOM)

And, Tranquility, Houston. The RCS check looked mighty fine to us.

Ronald Evans (CAPCOM)

Columbia, Columbia, Houston. Over.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.

Ronald Evans (CAPCOM)

Columbia, Houston in the blind—high gain. Pitch minus 20, yaw plus 150.

Buzz Aldrin (LMP)

Houston, Tranquility. Could you give me the fixed portion of the ascent PAD so I can load it in for a P57? Over.

Ronald Evans (CAPCOM)

Tranquility. Roger. Stand by one. We want to wait on that P57 until about TIG minus 50 minutes. Over.

Ronald Evans (CAPCOM)

Columbia, Columbia, Houston. Over.

Ronald Evans (CAPCOM)

Columbia, Columbia, Houston. Over.

Buzz Aldrin (LMP)

Houston, Tranquility. It turns out that detent 4 isn't usable anyway with the yaw that we have, because the Earth appears in both detent 2 and detent 3.

Ronald Evans (CAPCOM)

Tranquility Base, Houston. Roger.

Ronald Evans (CAPCOM)

Columbia, Houston. Over.
