| Day 5: Undocking and Landing | Journal Home Page | Day 6: Lunar Lift-off to Docking |
[This part of the transcript commences as Columbia and Eagle re-appear from the far side of the Moon, with Eagle already in its descent orbit. Armstrong and Aldrin make a successful lunar landing, while Collins in Columbia listens in.]
[The following section of transcript starts at the same point as the ALSJ chapter The First Lunar Landing. Its ending coincides with the end of the same chapter in the ALSJ.]
[ Note to WDW: We will not publish this substantial overlap with the ALSJ in this edition of the A11 FJ. This chapter version will not be proof-read until after completion of later chapters. ]
102:15:02 CC: Columbia, Houston. We're standing by. Over.
102:15:36 CC: Columbia, Houston. Over.
102:15:41 Collins: Houston, Columbia. Reading you loud and clear. How me?
102:15:43 CC: Roger. Five-by, Mike. How did it go? Over.
102:15:49 Collins: Listen, babe. Everything's going just swimmingly. Beautiful.
102:15:52 CC: Great. We're standing by for Eagle.
102:15:57 Collins: Okay. He's coming along.
102:16:00 CC: We copy. Out.
102:16:09 CC: And, Columbia, Houston. We expect to lose your High Gain sometime during the powered descent. Over.
102:16:19 Collins: Columbia. Roger. You don't much care do you?
102:16:22 CC: No, sir.
PAO: We have Acquisition Of Signal from the LM.
102:17:27 Aldrin: Houston, Eagle. How do you read?
102:17:29 Duke: Five-by, Eagle. We're standing by for your burn report. Over.
[End of temporary over-lap with the preceding chapter in the Apollo 11 Flight Journal.]
102:17:36 Aldrin: 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...
102:18:25 CC: Columbia, Houston. We've lost all data with Eagle. Please have him reacquire on the high gain, Over.
102:18:37 Collins: Eagle, this is Columbia. Houston would like you to reacquire on the high gain. They've lost your data. Over.
102:18:50 Collins: Eagle, did you copy Columbia?
102:18:54 CC: : Eagle, Houston. Did you call?
102:19:05 Aldrin: Eagle, Houston - Houston, Eagle. ? How do you read now?
102:19:08 CC: 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.
102:19:19 Aldrin: Roger. AGS residuals: minus 0.1, minus 0.2, minus 0.7. And we used the PGNS NOUN _36 for DELTA-V Z 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.
102:19:54 CC: Roger. Copy. Looks great.
PAO: Guidance says we're GO.
PAO: Now 12 minutes, 54 seconds to ignition. Gene Kranz just replied his flight controllors were off to a good start. Play it cool.
PAO: 12 minutes now until ignition for powered descent. Everything still looking very good at this point.
PAO: We presently show the LM at an altitude of 12.9 nautical miles and descending.
102:22:37 CC: Columbia, Houston. We've lost Eagle again. Have him try the high gain. Over.
102:22:46 Collins: Eagle, this is Columbia. Houston lost you again. They're requesting another try at the high gain.
102:23:57 CC: Eagle, Houston. We have you now. Do you read? Over ?
102:24:02 Aldrin: Loud and clear.
102:24:04 CC: Roger. We see your VERB 47.
102:24:12 Aldrin: 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.
102:24:23 CC: Roger. We'll work on it.
PAO: Aldrin is referring to the LM steerable antenna. That comment about the oscillations.
102:24:38 Armstrong: Horizon checklist right on time.
102:24:41 CC: Roger.
102:24:45 Aldrin: Did you copy the star - I mean the Sun check, Charlie?
102:24:48 CC: That's affirmative. We did, Buzz. Out.
PAO: Eagle is now at 10.7 nautical miles, 7 minutes, 37 seconds from ignition.
102:25:35 CC: Eagle, Houston. The AGS initialization looked good to us. Over.
102:25:43 Aldrin: Roger.
102:26:28 Armstrong: Our radar checks indicate a 56000-foot perilune. (BAD SCAN ? TRY TO CONFIRM WITH OTHER SOURCES} Our visual altitude check steadying out at about 53 000.
102:26:37 CC: Roger. Copy.
102:26:55 Aldrin: And, Houston, we got a 500 alarm early in the program. Went to DESCENT l, proceeded on it, and we're back at AUTO again. Over.
102:27:06 CC: Roger. We saw that, Buzz. Thank you much. Out.
102:27:09 Aldrin: All right. I say again - Okay. That wasn't an alarm; that was a code. Okay.
102:27:14 CC: Roger. We saw that.
102:27:22 CC: Eagle, Houston. We recommend you yaw 10 right. It will help us on the high-gain signal strength. Over.
PAO: Coming up on 5 minutes to ignition. Gene Kranz getting a Go/No-Go for descent.
102:28:08 CC: Eagle, Houston. If you read, you're GO for powered descent. Over.
102:28:18 Collins: Eagle, this is Columbia. They just gave you a GO (COLUMBIA) for powered descent.
102:28:22 CC: Columbia, Houston. We've lost them on the high gain again. Would you please - We recommend they yaw right 10 degrees and reacquire.
102:28:34 Collins: Eagle, this is Columbia. You're GO for PDI and they recommend you yaw right 10 degrees and try the high gain again.
102:28:46 Collins: Eagle, you read Columbia?
102:28:48 Aldrin: Roger. We read you.
102:28:49 Collins: Okay.
102:28:51 CC: Eagle, Houston. We read you now. You're GO for PDI. Over.
102:28:57 Aldrin: Roger. Understand. AELD control circuit breakers. DECA GIMBAL AC - closed?
102:29:07 Armstrong: What?
102:29:0x Aldrin: DECA GIMBAL AC - closed? Circuit breaker? COMMAND OVERRIDE - off? GIMBAL ENABLE? RATE SCALE - 25.
102:29:23 CC: Eagle, Houston. Your alignment is GO on the AGS. On my Mark, 3 30 until ignition.
102:29:29 Aldrin: Roger.
102:29:33 CC: Mark.
102:29:34 CC: 3 30 until ignition.

102:35:30 Aldrin (onboard): Yes.
102:35:31 Armstrong (onboard): To SLEW?
102:35:32 Aldrin (onboard): SLEW.
102:35:43 Aldrin: Houston, I'm getting a little fluctuation in the - AC voltage now. Just the meter, maybe, huh?
102:35:51 CC: . Roger,
102:35:52 Aldrin: Could be our meter, maybe, huh?
102:35:54 CC: Stand by, Looking good.(BAD SCAN _ LOST TEXT) You're still looking good at 3, coming up 3 (BAD SCAN?.) minutes.
102:36:03 Armstrong (onboard): Okay, we went by the 3-minute point early. A little off.
102:36:11 Aldrin (onboard): Rate of descent looks real good. Altitude - right about on.

102:36:58 Aldrin (onboard): Yes, I think it's going to drop.
102:37:00 Aldrin: ... it's going to stop.
102:37:01 Armstrong (onboard): Boy, I tell you, this is much harder to do than it was -
102:37:09 Aldrin (onboard): Keep it going.
