Buzz Aldrin (LMP)

Okay. We just got seven tenths on the radar.

Michael Collins (CMP)

Yes. I'm oscillating between 0.69 and seven tenths.

Buzz Aldrin (LMP)

Very good. We've got 4200 on the … meter.

Michael Collins (CMP)

I'm steady on 70 now. Yes. I read you sort of scratchy, but I read you.

Michael Collins (CMP)

Houston, Apollo—or Houston, Columbia. Over.

Charlie Duke (CAPCOM)

Roger. Go, Columbia. Over.

Michael Collins (CMP)

Roger. I still need a DOI P76 PAD, and a PDI 1 plus 12 P76 PAD sometime at your convenience.

Charlie Duke (CAPCOM)

Columbia, Houston. DOI P76 PAD, if you're ready to copy. Over.

Charlie Duke (CAPCOM)

Roger, Mike. NOUN 80—correction, NOUN 84: minus 00758, plus all zeros, plus 00098; NOUN 33: 101 36 1400, and stand by for the PDI plus 12.

Charlie Duke (CAPCOM)

Columbia, Houston, with the PDI plus 12 NOUN 84, if you're ready to copy.

Charlie Duke (CAPCOM)

Roger. NOUN 84: plus 01223, minus all zeros, plus 01889; NOUN 33: 102 44 2700, PDI plus 12 burn time is 046, burn time for DOI is 030. Ready for your readback. Over.

Michael Collins (CMP)

Roger. DOI P76: 84 is minus 00758, all balls, plus 00098, at 101 36 1400; plus 01223, minus all balls, plus 01889, 102 44 2700; burn time 46 and 30 seconds.

Charlie Duke (CAPCOM)

Roger. One error, Columbia, on the TIG for DOI; seconds was 1407. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. We'd like you to turn off your rotational direct—rotational control power direct number 2 off. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. On those P76's, a friendly reminder from your FIDO: add half the burn time to the TIG. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. We've lost data with Eagle. Will you please have him select aft OMNI? Over.

Michael Collins (CMP)

Eagle, this is Columbia. Houston would like you to select aft OMNI.

Buzz Aldrin (LMP)

Roger. I got it now. Houston, you reading Eagle now on aft OMNI?

Charlie Duke (CAPCOM)

That's affirmative, Eagle. Reading you five by.

Charlie Duke (CAPCOM)

Columbia, Houston. We'll have LOS at 101 28. AOS for you 102 15. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. It appeared to us when you were doing the P52, maneuvering the S band, the high gain went into the stop. Verify that both S band breakers are in. Over.

Buzz Aldrin (LMP)

Roger. I think I'd gone up to 90.0 before it went there. The one on this side is in and I'll check the other later.

Charlie Duke (CAPCOM)

Eagle, Houston. You are GO for DOI. Over.

Buzz Aldrin (LMP)

Roger. GO for DOI. Do you have LOS and AOS times?

Charlie Duke (CAPCOM)

Roger. For you LOS at 101 28. AOS 102 16. Over.

Charlie Duke (CAPCOM)

And, Buzz, S band steerable update for you on the angles at AOS: 219 and yaw 30. Over.

Buzz Aldrin (LMP)

Roger. That's in the flight plan. Thank you.

Michael Collins (CMP)

Houston, Columbia. How are all the systems looking?

Michael Collins (CMP)

Just wanted to get a systems check from you sometime prior to LOS.

Neil Armstrong (CDR)

Houston, Eagle. You can—Torquing angles NOUN 93 on four zeros and a 3 are minus 00292, plus 00289, minus 00094.

Charlie Duke (CAPCOM)

Roger. Copy. Stand by. Roger, Eagle. You can torque it. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. Your systems are looking good going over the hill. Approximately 7 minutes to LOS.

Charlie Duke (CAPCOM)

Eagle, Houston. Place the BIOMED to Commander. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. We've lost the high bit rate. Would you please select low bit rate? Over.

Charlie Duke (CAPCOM)

And, Eagle, on my Mark we'll have 12 minutes to ignition. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. Stand by for my Mark.

Charlie Duke (CAPCOM)

Twelve minutes to ignition.

Charlie Duke (CAPCOM)

Columbia/Eagle, Houston. Three minutes to LOS. Both looking good going over the hill.

Charlie Duke (CAPCOM)

Columbia, Houston. We're standing by. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. Over.

Michael Collins (CMP)

Houston, Columbia. Reading you loud and clear. How me?

Charlie Duke (CAPCOM)

Roger. Five by, Mike. How did it go? Over.

Michael Collins (CMP)

Listen, babe. Everything's going just swimmingly, Beautiful.

Charlie Duke (CAPCOM)

Great. We're standing by for Eagle.

Michael Collins (CMP)

Okay, He's coming along.

Charlie Duke (CAPCOM)

And, Columbia, Houston. We expect to lose your high gain sometime during the powered descent. Over.

Michael Collins (CMP)

Columbia. Roger. You don't much care do you?

Buzz Aldrin (LMP)

Houston, Eagle. How do you read?

Charlie Duke (CAPCOM)

Five by, Eagle. We're standing by for your burn report. Over.

Buzz Aldrin (LMP)

Roger. The burn was on time. The residuals before nulling: minus 0.1, minus 0.4, minus 0.1, X and Z nulled to zero … nulling …

Charlie Duke (CAPCOM)

Columbia, Houston. We've lost all data with Eagle. Please have him reacquire on the high gain, Over.

Michael Collins (CMP)

Eagle, this is Columbia. Houston would like you to reacquire on the high gain. They've lost your data. Over.

Michael Collins (CMP)

Eagle, did you copy Columbia?

Charlie Duke (CAPCOM)

Eagle, Houston. Did you call?

Buzz Aldrin (LMP)

Eagle, Houston—Houston, Eagle. How do you read now?

Charlie Duke (CAPCOM)

Roger. Five by, Neil. We copied up to the AGS residuals. Would you please repeat the AGS residuals in the trim—correction—the Sun check? Over.

Buzz Aldrin (LMP)

Roger. AGS residuals: minus 0.1, minus 0.2, minus 0.7. And we used the PGNS NOUN 86 for DELTA-VZ which was 9.5, versus yours which was 9.1, and I believe that may explain the difference. Apogee 57.2, perilune 9.1, Sun check to three marks, NOUN 20, minus NOUN 22, plus 0.19, plus 0.16, plus 0.11. Over.

Charlie Duke (CAPCOM)

Roger. Copy. Looks great.

Charlie Duke (CAPCOM)

Columbia, Houston. We've lost Eagle again. Have him try the high gain. Over.

Michael Collins (CMP)

Eagle, this is Columbia. Houston lost you again. They're requesting another try at the high gain.

Charlie Duke (CAPCOM)

Eagle, Houston. We have you now. Do you read? Over.

Charlie Duke (CAPCOM)

Roger. We see your VERB 47.

Buzz Aldrin (LMP)

Yes. I don't know what the problem was there. It just started oscillating around in yaw. According to the needle, we're picking up a little oscillation right now, as a matter of fact.

Charlie Duke (CAPCOM)

Roger. We'll work on it.

Neil Armstrong (CDR)

Horizon checklist right on time.

Buzz Aldrin (LMP)

Did you copy the star—I mean the Sun check, Charlie?

Charlie Duke (CAPCOM)

That's affirmative. We did, Buzz. Out.

Charlie Duke (CAPCOM)

Eagle, Houston. The AGS initialization looked good to us. Over.

Neil Armstrong (CDR)

Our radar checks indicate 50,000 foot perilune. Our visual altitude checks steadying out at about 53,000.
