Spacelog Apollo 11

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

Roger. You got him.

Thank you, sir.

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

You got it.

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

Roger.

Eagle, Houston. Stand by for my Mark.

MARK.

Twelve minutes to ignition.

We copy.

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

Columbia. Roger.

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

Columbia, Houston. Over.

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

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

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

Great. We're standing by for Eagle.

Okay, He's coming along.

We copy. Out.

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

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

No, sir.

Houston, Eagle. How do you read?

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

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 …

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

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

Eagle, did you copy Columbia?

Eagle, Houston. Did you call?

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

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.

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.

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

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

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

Loud and clear.

Roger. We see your VERB 47.

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.

Roger. We'll work on it.

Horizon checklist right on time.

Roger.

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

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

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

Roger.

Roger. We saw that.

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

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

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

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

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

Eagle, you read Columbia?

Roger. We read you.

Okay.

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

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

What?

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

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

Roger.

Mark.

3 30 until ignition.

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 …

Hit VERB 77?

Okay. Sequence camera coming on.

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

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

Roger.

Say again the angles, though.

Roger.

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

Roger. Pitch 212, yaw plus 37.

OMNI's in.

… 10 … 10 percent …

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

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

…

Say again, Neil?

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

Okay. You should have him now, Houston.

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

Eagle —

— descent looks good.

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

Roger. Copy.

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

Copy.

AGS and PNGS agree very closely.

Roger.

Beta ARM. Altitudes are a little high.

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