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.

Buzz Aldrin (LMP)

And, Houston, we got a 500 alarm early in the program. Went to DESCENT 1, proceeded on it, and we're back at AUTO again. Over.

Charlie Duke (CAPCOM)

Roger. We saw that, Buzz. Thank you much. Out.

Buzz Aldrin (LMP)

All right. I say again—Okay. That wasn't an alarm; that was a code. Okay.

Charlie Duke (CAPCOM)

Eagle, Houston. We recommend you yaw 10 right. It will help us on the high gain signal strength. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. If you read, you're GO for powered descent. Over.

Michael Collins (CMP)

Eagle, this is Columbia. They just gave you a GO for powered descent.

Charlie Duke (CAPCOM)

Columbia, Houston. We've lost them on the high gain again. Would you please—We recommend they yaw right 10 degrees and reacquire.

Michael Collins (CMP)

Eagle, this is Columbia. You're GO for PDI and they recommend you yaw right 10 degrees and try the high gain again.

Michael Collins (CMP)

Eagle, you read Columbia?

Charlie Duke (CAPCOM)

Eagle, Houston. We read you now. You're GO for PDI. Over.

Buzz Aldrin (LMP)

Roger. Understand. AELD control circuit breakers. DECA GIMBAL AC—closed?

Buzz Aldrin (LMP)

DECA GIMBAL AC—closed? Circuit breaker? COMMAND OVERRIDE—off? GIMBAL ENABLE? RATE SCALE—25.

Charlie Duke (CAPCOM)

Eagle, Houston. Your alignment is GO on the AGS. On my Mark, 3 30 until ignition.

Buzz Aldrin (LMP)

Roger. Copy. Thrust translation—four jets—Balance couple—ON. TTCA throttle—MINIMUM. Throttle—AUTO CDR. Prop button—RESET. Prop button. Okay. ABORT/ABORT STAGE—RESET. ATT CONTROL—three of them to MODE CONTROL. Okay, MODE CONTROL is set. AGS is reading 400 plus 1. Standing by for …

Buzz Aldrin (LMP)

Okay. Sequence camera coming on.

Charlie Duke (CAPCOM)

Eagle, Houston. If you'd like to try high gain, pitch 212, yaw 37. Over.

Buzz Aldrin (LMP)

Roger. I think I've got you on high gain now.

Buzz Aldrin (LMP)

Say again the angles, though.

Buzz Aldrin (LMP)

I'll set them in to use them before we yaw around.

Charlie Duke (CAPCOM)

Roger. Pitch 212, yaw plus 37.

Buzz Aldrin (LMP)

… 10 … 10 percent …

Charlie Duke (CAPCOM)

Columbia, Houston. We've lost them. Tell them to go aft OMNI. Over.

Michael Collins (CMP)

They've lost you. Use the OMNI's again.

Buzz Aldrin (LMP)

I'll leave it in SLEW. Relay to us. See if they have got me now. I've got good signal strength in SLEW.

Michael Collins (CMP)

Okay. You should have him now, Houston.

Charlie Duke (CAPCOM)

Eagle, we've got you now. It's looking good. Over.

Buzz Aldrin (LMP)

— descent looks good.

Charlie Duke (CAPCOM)

Eagle, Houston. Everything is looking good here. Over.

Charlie Duke (CAPCOM)

Eagle, Houston. After yaw around, angles: S band pitch, minus 9, yaw plus 18.

Buzz Aldrin (LMP)

AGS and PNGS agree very closely.

Buzz Aldrin (LMP)

Beta ARM. Altitudes are a little high.

Buzz Aldrin (LMP)

Houston. I'm getting a little fluctuation in the AC voltage now.
