Spacelog Apollo 11

Houston, Columbia. My rendezvous radar transponder is operating.

Spacecraft calling Houston? Say again.

This is Columbia saying the rendezvous radar transponder is operating.

Roger. Copy, Columbia.

Roger. We're going to a torque.

Houston. Roger.

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

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.

Tranquility, Houston. Roger.

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.

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

Are you getting the information on the downlink now?

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

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

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

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

Tranquility, Houston. Negative on VERB 83.

Understand.

We just lost lock.

Tranquility, Houston. Go.

They've just lost lock, Ron.

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.

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?

Houston, Columbia. You got NOUN 49. Five good marks.

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

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

Columbia, Houston. Say again about your NOUN 49.

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

Columbia, Houston. Stand by one.

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

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

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

Roger. Will do.

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

I have. I'm running fast.

Roger.

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

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

Tranquility, Houston.

Roger. Go ahead.

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.

Roger. Go ahead with the K factor.

Roger. 119 plus 59 plus 59.92. Over.
