124:31:14 Aldrin: The AGS has 9.5, 46.6.

124:31:23 Evans: Eagle, Houston. Copy. [Long pause.]

[Having just queried the PGNCS about the size of their orbit, Buzz has asked the AGS for its determination. PGNCS: 47.3 by 9.5 nautical miles (87.6 by 17.6 km). AGS: 46.6 by 9.5 (86.3 by 17.6 km). The two systems with their independent gyros and accelerometers are in remarkable agreement.]
124:31:25 Armstrong (onboard): Okay.

124:31:44 Evans: Eagle, Houston. Request abort stage, reset; engine stop, reset; and mode control to Att Hold when you get a chance to.

124:31:52 Aldrin: Roger. [Long pause.]

124:32:16 Aldrin (onboard): You want to try...?

124:32:20 Armstrong (onboard): Yes.

124:32:23 Aldrin (onboard): Circuit breakers in - or do you want to go to align?

124:32:28 Armstrong (onboard): Maybe we'd better get an alignment...

124:32:31 Aldrin (onboard): Okay....

124:32:40 Armstrong (onboard): Yes.

PAO: Here in Mission Control the scribing plotter showing the velocity and height - here we go again.

124:32:44 Evans: Eagle, Houston. You can go ahead and proceed with P52 as per nominal.

124:32:52 Armstrong: Roger, Houston. The Eagle is back in orbit, having left Tranquility Base and leaving behind a replica from our Apollo 11 patch and the olive branch.

124:33:15 Evans: Eagle, Houston. Roger. We copy. The whole world is proud of you. [Pause.]

124:33:26 Armstrong: We had a lot of help down there. [Pause.]

124:33:27 Aldrin (onboard): We're going to have to have our rendezvous radar circuit breakers in anyway to get on to your link.

124:33:30 Armstrong (onboard): Yes.

124:33:37 Collins: Eagle, Columbia. I've got 470 now for R-dot, and I just broke lock. Could you hold silent for a few seconds here while I re-acquire. [Long pause.]

124:33:45 Aldrin (onboard): Okay.

124:34:05 Armstrong (onboard): Okay.

124:34:09 Aldrin (onboard): Inverter 2, Inverter 1, circuit breaker open?

124:34:09 Collins: Columbia's re-acquired you.

[Comm break.]
PAO: Here in Mission Control, the scribing plotters have been replaced with the lunar orbit tracking chart showing Eagle behind Spider [means Columbia] some 20 degrees in longitude. Flight Operations Director Chris Kraft commented that he felt like some 500 million people around the world are helping push Eagle off the Moon and back into orbit. We're continuing to monitor transmissions between the ground and Eagle and Columbia. Apollo Control standing by.

[The PAO has slipped up in saying Spider, the code-name of the Apollo 9 LM, when he means Columbia, the Apollo 11 CM.]
124:34:11 Armstrong (onboard): I got Inverter 1.

124:34:28 Aldrin (onboard): Close the AOT Lamp circuit breaker -

124:34:44 Armstrong (onboard): Going to Track here.

124:34:50 Aldrin (onboard): Yes.

124:34:52 Armstrong (onboard): That right?

124:34:53 Aldrin (onboard): Right.

124:35:19 Armstrong (onboard): You know, I didn't see a lot of dust in the cockpit, did you?

124:35:22 Aldrin (onboard): No, there was a fair amount. What did you get, 283?

124:35:23 Evans: Columbia, Houston. Request P00 and Accept, and we'll give you a good ole LM vector. Over.

124:35:31 Armstrong (onboard): Yes.

124:35:37 Collins: Roger. Houston. Going to Accept.

[Comm break.]

[MP3 audio file. 7,296 kB.]

124:37:29 Evans: Eagle, Houston. You can go ahead and turn your Up-Datalink switch off.

124:37:39 Aldrin: Roger. It's off.

124:37:41 Evans: Roger.

[Comm break.]
PAO: This is Apollo Control. During the ascent phase, the heart rates on the Eagle crew reached 90 for Neil Armstrong, 120 for Buzz Aldrin. They're now back down in the 80s. We're some 28 minutes, 15 seconds from Loss Of Signal with Columbia; 29 minutes, 52 seconds away from Loss Of Signal on Eagle.

124:39:06 Evans: Columbia, Houston. The computer is yours. Press on.

124:39:12 Collins: Okay.

124:39:24 Aldrin: Houston, the AGS has a Delta-H of 15.5.

124:39:31 Evans: Eagle, Houston. Roger. 15.5.

124:39:33 Aldrin: And a maneuver of - and a maneuver of 51.3.

124:39:41 Evans: Roger. We copy. And, Eagle, aft Omni. Over.

124:39:55 Aldrin: Roger. Aft Omni. [Pause.] [Garble.] [Long pause.]

124:40:25 Evans: Columbia, Houston. [Long pause.]

124:41:20 Aldrin: Roger. It's on.

124:41:26 Aldrin: And I can see it reflecting out my window, so it must be working. [Long pause.]

124:41:43 Evans: Eagle, Houston in the blind. Try low bit rate. Over. [Pause.]

124:41:55 Aldrin: Roger. Low bit rate. I've got a 3.8 signal strength. Over. [Long pause.]

124:42:13 Evans: Eagle, Houston. Roger. We copy your signal strength, 3.8. [Long pause.]

124:42:51 Aldrin: 37, I believe.

124:42:56 Armstrong: [Garble] chart. [Long pause.]

124:43:37 Aldrin: [Garble.]

124:43:42 Collins: [Garble.]

124:43:46 Aldrin: Sounds good, Mike. [Long pause.]

124:44:46 Aldrin: Pull it out. [Garble.] [Long pause.]

124:45:10 Aldrin: [Garble.]

[Comm break.]

[MP3 audio file. 8,546 kB.]

124:46:57 Aldrin: [Garble.] [Long pause.]

124:47:11 Aldrin: [Garble.]

124:47:37 Aldrin: [Garble.] [Long pause.]

124:47:49 Unknown speaker: [Garble.]

124:47:51 Aldrin: [Garble.] [Pause.]

124:48:00 Evans: Eagle, Houston.

124:48:06 Armstrong: Roger. Go ahead.

124:48:07 Evans: Roger. We saw a very slight jump in cabin and suit pressure there. Could you verify cabin Repress valve is closed? [Pause.]

124:48:24 Armstrong: Okay. It's closed.

124:48:26 Evans: Roger. And we've got about 1 minute to before where you ought to be radar tracking, and we've lost data with you.

124:48:40 Aldrin: Okay. [Garble.] [Long pause.]

124:49:03 Aldrin: Okay. Get a pass. [Long pause.]

124:49:26 Aldrin: Got it? [Garble.] Enter. Seventy six. You got it in the backgroound, huh?. [Pause.]

124:49:42 Collins: Eagle, Columbia. You can turn your track light off.

124:49:46 Aldrin: Okay. You got it?

124:49:48 Armstrong: Yes.

124:49:50 Aldrin: All ready to mark, X and Y. Okay. Marked X now.

124:49:58 Collins: Houston, Columbia.

124:50:02 Aldrin: X or Y? Maybe we ought to be satisfied with three of them.

124:50:15 Collins: Eagle, Columbia. Your track light still on?

124:50:21 Evans: Columbia, Houston...

124:50:22 Aldrin: That light is still on.

124:50:23 Evans: ...Say again.

124:50:25 Aldrin: X or Y?

124:50:26 Collins: [Garble.]

124:50:35 Aldrin: I can't tell. [Long pause.]

124:50:54 Aldrin: Okay. Mark Y.

124:51:06 Aldrin: That enough? Beautiful! All zeros. Okay. Let's torque them. I'll write them down. Minus 06, plus 64, plus 137. Torque [garble]. Radar circuit breakers in? [Long pause.]

124:51:57 Collins: I got a [garble] mark on [garble] track light [garble] drive you right in the middle [garble] attitude about that time.

124:52:06 Armstrong: Yeah. We're pointed down pretty much. We're going to be up...

124:52:08 Aldrin: Okay. [Garble.] circuit...

124:52:12 Collins: Okay.

124:52:13 Aldrin: ...breaker in? Both circuit breakers in?

124:52:18 Collins: Eagle, Columbia. I got a solid mark on [garble.]

124:52:26 Aldrin: Okay. Auto maneuver.

124:52:36 Collins: Okay, I got your track light back. Thank you much.

124:52:40 Evans: Columbia, Houston. Did you call? [Pause.]

124:52:51 Collins: That's affirmative. I called you before about the VHF ranging. It's not working. [Garble.]

124:53:01 Aldrin: Houston, Eagle. Did you copy our star angle difference and torquing angles.

124:53:07 Evans: Eagle, Houston. We didn't have them on the downlink but we copied them on the Vox.

124:53:18 Aldrin: Okay. It was zero for star angle difference, minus 06, plus 64, and plus 1.37. Over.

124:53:28 Evans: Eagle, Houston. Roger. We have that. [Long pause.]

124:54:02 Aldrin: That's it. Got a good lock-on, Houston. [Long pause.]

124:54:26 Aldrin: [Garble] take that. [Long pause.]

124:54:59 Aldrin: How about that? [Long pause.]

124:55:28 Aldrin: You really think its apogee is 125 21, huh? [Garble.] That circuit breaker is in. [Pause.]

124:55:54 Aldrin: Engine arm circuit breaker.

[Comm break.]

[MP3 audio file. 6,299 kB.]

124:57:03 Aldrin: Okay. There's a mark. Buy that? [Long pause.]

124:57:24 Evans: Eagle, Houston. If you have time, pitch 162, yaw minus 16. [Long pause.]

[These are angles to which the steerable dish antenna can be aimed in an effort to improve communications.]
124:58:32 Aldrin: You load the REFSMMAT? Okay.

124:58:36 Collins: Eagle, Columbia. Your Y-dot is minus 1.0. Over.

124:58:44 Armstrong: Mike, you're [garble].

124:58:53 Collins: Eagle, do you read Columbia? Over. [Pause.]

124:59:04 Collins: Eagle, this is Columbia. Over.

124:59:10 Collins: Houston, Columbia. Over.

124:59:12 Evans: Roger, Columbia. Loud and clear now. This is Houston.

124:59:17 Collins: Roger. Would you tell Eagle his Y-dot is minus 1.0. Over.

124:59:24 Evans: Roger. Eagle, Columbia says your Y-dot is minus 1.0. Over.

124:59:37 Armstrong: Roger, Houston. We got that. Thank you.

124:59:39 Evans: Roger. And you can go high bit rate now - Eagle can. [Long pause.]

125:00:13 Aldrin: [Garble] set up ORDEAL. [Long pause.]

125:00:29 Collins: Eagle, Columbia. How do you read? [Long pause.]

125:00:44 Aldrin: AGS agrees very closely, and pointing [garble] direction.

125:00:57 Collins: Houston, Columbia is unable to read Eagle on either antenna or on VHF duplex Bravo. You got any suggestions?

125:01:07 Evans: Roger, Columbia. We understand you are unable to read Eagle. Stand by. [Pause.]

125:01:23 Armstrong: Houston, tell Columbia that we read him about strength 2. [Long pause.]

125:02:00 Aldrin: Okay. Wide deadband on.

125:02:04 Collins: Houston, Columbia. Also my VHF ranging is not working now, and I'd like to know whether you'd like me to continue making sextant marks or do nothing. I'm supposed to be doing VHF marks only, and it's for the next 6 or 7 minutes.

125:02:20 Evans: Columbia, Houston. Roger. We copy. And, Eagle, looks like the best antenna would be forward for the LM. And, break. Eagle, we missed your loading of the TPI TIG and P32. Could you confirm you've done that? [Long pause.]

125:03:00 Evans: Columbia, Houston. Recommend you take sextant marks and do not re-initialize. Over. [Pause.]

125:03:15 Collins: Roger, Houston. Columbia's got the VHF ranging back now. I'll stick with the nominal. Thank you.

125:03:20 Evans: Roger. Mighty fine. [Long pause.]

125:03:38 Collins: Columbia reading you loud and clear now, Eagle.

[Comm break.]

[MP3 audio file. 10.0 MB.]

125:04:54 Evans: Columbia, Houston.

125:05:00 Collins: Go ahead, Houston.

125:05:02 Evans: Roger. Mike, you can go ahead and get as many VHF and sextant marks as you can here in this period of time.

125:05:12 Collins: Roger that. [Pause.] I've just got time for maybe two sextant marks, then get on with the final count. [Long pause.]

125:05:57 Evans: Eagle and Columbia, about 1 minute to LOS there on Columbia. It looks like we have about 51.5 for CSI, and we tend to confirm your Y-dot. And, break. For Eagle, verify VHF Bravo transmitter is off.

[The ground's computation of the CSI maneuver is 51.5 feet per second (15.7 m/s) which, as Neil will reveal on the onboard recording, equals the solution in the LM.]
125:06:22 Aldrin: Roger. VHF Bravo is off.

125:06:35 Evans: Eagle, Houston. Recommend aft Omni and are you Go for CSI, so we can let Columbia know. Over.

125:06:47 Aldrin: Roger. We're Go for CSI.

125:06:52 Evans: Columbia, Houston. Did you copy? Eagle is Go for CSI.

125:06:58 Collins: No, I did not copy. I'm reading them only intermittently, but thank you.

125:07:02 Evans: Roger.

[Comm break.]
125:07:08 Armstrong (onboard): Okay.

PAO: This is Apollo Control. Columbia has gone behind the Moon. Still a little over a minute left until Eagle goes behind the Moon. We'll catch these last few minutes of tracking and any possible conversation.

125:07:39 Armstrong (onboard): No. We'll wait until CDH.

125:08:09 Evans: Eagle, Houston. We'll see you coming around the other side. Your AOS times are 1 minute ahead of the Flight Plan.

125:08:18 Armstrong: Okay. Thank you.

[Very long comm break.]
125:08:37 Armstrong (onboard): Okay.

125:09:31 Armstrong (onboard): No, I didn't. Go ahead, Mike.

125:09:39 Armstrong (onboard): I think we are now, finally, and I think I have you in sight.

125:09:57 Armstrong (onboard): We have 51.5.

125:10:19 Armstrong (onboard): Well, the ground's got 51.5, and we got 51.5. Yes. First time we've ever agreed on anything.

125:10:41 Aldrin (onboard): Want these... first?

125:10:43 Armstrong (onboard): Not yet.

125:10:45 Aldrin (onboard): I don't know why.

PAO: This is Apollo Control. We have had Loss Of Signal with Eagle. Quite scratchy as Eagle went over the hill to complete the 25th lunar revolution as it gets to the midpoint on the lunar far side. Ascent burn just completed went quite well; on time at 124 hours, 22 minutes, 0 seconds Ground Elapsed Time. Coming up on this rev, approximately 10 minutes from now as a matter of fact, will be the Concentric [also known as 'Coelliptic'] Sequence Initiate maneuver, CSI, which will raise the Eagle's perilune to some 45 nautical miles. Eagle now is in an orbit measuring 9.4 nautical miles [17.4 km] at insertion or perilune, and 46.7 [86.5 km] at apolune. This CSI maneuver will be made approximately at apolune. Therefore, the effect takes place 180 degrees later and has the effect of raising perilune to the desired 45 nautical miles [83.3 km]. This maneuver will take place at 125 hours, 19 minutes, 34.7 seconds. He will have a Delta-V or velocity change of 51.5 feet per second [15.7 m/s]. All of these maneuvers, incidentally, in the rendezvous sequence by Eagle, will be made by the - using the Reaction Control System of Eagle. Following the CSI; at 126 hours, 18 minutes, 0 seconds; a 9.2 foot per second [2.8 m/s] burn, probably mostly a radial burn; at 126 hours, 18 minutes will twist the Eagle's orbit to equal distance from the orbit of Columbia, what they call a Constant Delta Height, or CDH maneuver. At 126 hours, 57 minutes, 00 seconds; Terminal Phase Initiate, TPI. In this maneuver, the crew visually thrust along the line of sight toward Columbia when the line of sight is some 27 degrees above the local horizontal. This maneuver will have a magnitude of about 24.9 feet per second [7.6 m/s], and, in turn, it raises the apolune to 60.5 nautical miles [112.0 km], which is approximately the altitude Columbia is orbiting. Terminal Phase Finalization, TPF; 127 hours, 39 minutes, 39.2 seconds. This is the start time for a series of small burns which are a combination of midcourse corrections and velocity match maneuvers to bring Eagle in with Columbia and match the velocity so that they station-keep for a short period for photography, etc., and move on into docking at approximately 128 hours Ground Elapsed Time. In all of these maneuvers, Mike Collins aboard Columbia is spring loaded to do what is called a mirror image maneuver approximately a minute after the Eagle is scheduled to make its maneuver, and if for some reason Eagle cannot make the maneuver, Collins would do the exact same maneuver only in reverse so that Columbia would in effect begin a CSM-active rendezvous with Eagle. As Eagle went over the hill on the 25th revolution, a velocity was being measured at 5,410 feet per second [1,649 m/s]. Eagle's weight somewhat lighter than when it started out in excess of 32,000 pounds [14,500 kg] - it's now shrunk to some 5,885 pounds [2,669 kg]. Some 39 minutes, 20 seconds away from acquisition of Columbia; 41 minutes, 45 seconds from acquisition of Eagle; as the two vehicles come around on the 26th lunar revolution. The crew will likely describe how the CSI burn went, which is some 5 minutes away from this point. And at 125 hours, 14 minutes Ground Elapsed Time, this is Apollo Control.

125:11:17 Aldrin (onboard): I had to turn my S-band off so I could hear him - my S-band switch on the audio panel. Woo-woo!

125:11:31 Armstrong (onboard): Yes, that works good.

125:11:51 Aldrin (onboard): Not at this point, no.

125:12:42 Armstrong (onboard): Okay.

125:13:11 Aldrin (onboard): [Garble.] Hey, Mike, how do you read me?

125:13:24 Aldrin (onboard): Okay, let's go to B Data on your command.

125:13:59 Collins (onboard): Eagle, Columbia.

125:14:06 Aldrin (onboard): Loud and clear.

125:14:10 Aldrin (onboard): Affirmative. We're at the burn attitude, too.

125:15:10 Collins (onboard): Eagle, Columbia. When you get a chance, could you give me the - the CSI P76 PAD and your Noun 84 and your Noun 33?

125:15:21 Aldrin (onboard): Yes, we'll do that in a minute.

125:15:25 Collins (onboard): Alright.

125:15:50 Aldrin (onboard): Okay, Mike, you want the burn time and the Noun 81. Is that right?

125:16:00 Aldrin (onboard): Okay, the burn time is 125:19:34.7, and the burn is 51.5, zero, and zero.

125:16:16 Collins (onboard): Okay, I understand. Plus 51.5, zeros, and zeros, and you're using 125:19:34.70. Thank you kindly.

125:18:45 Collins (onboard): I'm in maneuver attitude, all set to burn if necessary. I've got about 45 miutes to Tig - 45 seconds to Tig.

125:18:51 Aldrin (onboard): Okay.

125:19:46 Aldrin (onboard): We're burning, Mike.

125:21:36 Aldrin (onboard): Burn complete, Mike.

125:21:39 Collins (onboard): Good show.

125:22:59 Aldrin (onboard): Okay, Mike, our CDH time is 126:17:45.58. Over.

125:23:12 Collins (onboard): Roger, copy. CDH, 126:17:45.58.

125:23:21 Aldrin (onboard): Affirmative.

125:28:33 Collins (onboard): Eagle, Columbia. I have you in an orbit 49.5 by 46.1 [nautical miles, 91.7 by 85.4 km].

125:28:43 Aldrin (onboard): Okay, thank you.

125:29:09 Collins (onboard): Eagle, Columbia. I'd like to go back to VHF Ranging configuration, please, on your mark.

125:29:15 Aldrin (onboard): Roger. On my mark...

125:29:17 Aldrin (onboard): Mark, VHF Ranging.

125:30:37 Aldrin (onboard): [Garble.]

125:30:40 Armstrong (onboard): Well, which way did I go?

125:30:42 Aldrin (onboard): [Garble] out of plane.

125:30:45 Armstrong (onboard): What?

125:30:46 Aldrin (onboard): Did you hear that?

125:30:57 Aldrin (onboard): Why you don't hear these 3 - 3,500-pound rocket engines when you're sitting on them, I'll never know.

[Most of the noise we associate with a rocket engine is produced by the violent and turbulent interaction of the exhaust gases with the atmosphere through which they flow. However, in the LM, the gases are expelled straight into a vacuum. What little noise comes up]
125:31:03 Armstrong (onboard): Yes.

125:31:08 Aldrin (onboard): [Garble] structure somehow.

125:31:31 Aldrin (onboard): 3.5, Neil.

125:32:44 Aldrin (onboard): Woo-woos is on VHF B...

125:32:48 Armstrong (onboard): [Garble] B?

125:32:50 Aldrin (onboard): Not on A.

125:32:58 Armstrong (onboard): (Laughter) That's your story, huh?

125:33:25 Armstrong (onboard): That's rugged country.

125:34:15 Aldrin (onboard): Yes, that perigee we're on [garble].

125:34:20 Armstrong (onboard): [Garble] alright, isn't it?

125:34:31 Aldrin (onboard): I got 4 feet forward and I got back 7 [garble].

125:34:38 Armstrong (onboard): Boy, this water separator sure isn't working worth a durn. Maybe we ought to try the other one - [garble] water. Oh boy, this thing is just really spitting it.

125:34:53 Aldrin (onboard): I sure do. It's been on - yes, we do - it's been on all the time.

125:35:06 Armstrong (onboard): We should see the tracking light now. That's it. Doesn't look [garble] but it's not - turned off.

125:35:16 Aldrin (onboard): Okay, let's try and get a Y-dot, or an R-dot, at 30 seconds.

125:35:21 Armstrong (onboard): It'll be the first time we've ever done it.

125:35:30 Aldrin (onboard): No, let me get comm.

125:35:48 Aldrin (onboard): We're really going to be crying.

125:35:50 Armstrong (onboard): [Simulated crying]

125:35:54 Armstrong (onboard): My - top thruster over here has got a lot of brown holes in it - in the exit nozzle.

125:36:05 Armstrong (onboard): See it?

125:36:06 Aldrin (onboard): Yes.

125:36:13 Aldrin (onboard): You know, these thrusters aren't used much over here. Well, maybe [garble] or something.

125:36:31 Armstrong (onboard): See it?

125:36:34 Aldrin (onboard): No.

125:36:46 Aldrin (onboard): When we get the Sun behind us, we might be able to.

125:37:04 Aldrin (onboard): Hey, I got to recycle. Then after [garble].

125:37:28 Aldrin (onboard): It's all over me.

125:37:38 Aldrin (onboard): Coming out of that vent back of my neck, isn't it? That where it's coming out?

[This appears to be a water leak, mentioned later at 126:13:01.]
125:38:44 Aldrin (onboard): Give us the CSI state vector - navigation difference - no updating CSI [garble].

125:39:02 Aldrin (onboard): Through AGS.

125:39:21 Aldrin (onboard): [Garble.]

125:39:45 Aldrin (onboard): Thinking about it.

125:39:51 Armstrong (onboard): You going to come up with a solution for us?

125:40:33 Armstrong (onboard): Range rate?

125:40:35 Aldrin (onboard): Range rate.

125:40:45 Aldrin (onboard): A lot of trouble having our [garble] up.

125:41:08 Aldrin (onboard): Range/range rate is [garble].

125:41:23 Aldrin (onboard): Yaw, damn it!

125:42:24 Collins (onboard): [Garble.]

125:42:28 Collins (onboard): [Garble] is up.

125:42:30 Aldrin (onboard): 125:47:45.58.

125:42:42 Collins (onboard): [Garble.]

125:43:17 Aldrin (onboard): [Garble] feet per second.

125:43:19 Armstrong (onboard): Both tanks were pressurized, weren't they?

125:43:21 Aldrin (onboard): Yes.

125:43:22 Armstrong (onboard): Sure shook them up. I remember that Gene said theirs didn't drop a bit - remember that - when they pressurized? Don't think theirs dropped at all.

[Armstrong is referring to Gene Cernan's Lunar Module Snoopy, on Apollo 10.]
125:44:37 Aldrin (onboard): Okay.

125:44:43 Armstrong (onboard): We're getting minus 2.9.

125:44:48 Aldrin (onboard): Going AGS all the way, huh?

125:44:50 Armstrong (onboard): Yes, forget it.

125:44:54 Aldrin (onboard): Get more tracking if we forget.

125:45:01 Armstrong (onboard): No, we'll just - we'll just wait until CDH.

125:46:19 Armstrong (onboard): You got a lot of film left in there?

125:46:23 Aldrin (onboard): About half.

125:46:26 Armstrong (onboard): You could run it some here. Oh, you just - you want to leave some for docking, huh?

125:46:50 Armstrong (onboard): [Garble.] Got that cockpit all cleaned up so that we got places for all our trash, Mike?

125:47:02 Collins (onboard): [Garble.]

125:47:21 Armstrong (onboard): Yes, we got them all over us - look like chimney sweeps.

125:47:36 Armstrong (onboard): You bet you. Nice to get home.

125:48:06 Aldrin (onboard): [Garble] up tracking...

125:48:22 Aldrin (onboard): Got that?

125:48:24 Armstrong (onboard): What do you need?

125:48:27 Aldrin (onboard): That right-angle bracket, the right-angle bracket, need that...

125:48:44 Armstrong (onboard): It's not over here. Well, that's a good day not to throw in some failures. See if we can run the nominal one time.

PAO: This is Apollo Control. 125 hours, 52 minutes Ground Elapsed Time. Less than 1 minute away from the acquisition of the spacecraft Columbia coming around on the near-side of the Moon on the twenty-sixth revolution. Some 3 minutes, 11 seconds away from Eagle's appearance on the lunar front side. Stand by here for word that we have acquired data and voice link. Spacecraft Communicator Ron Evans is standing by for AOS so that he can pass some information to the crew of the two spacecraft.

PAO: We have AOS of the spacecraft, Columbia.

125:52:58 Aldrin (onboard): CO2.

125:53:12 Armstrong (onboard): I don't think so, Mike, we got to - [garble].

125:53:24 Aldrin (onboard): [Garble] want to go to that - [garble].

125:53:26 Collins (onboard): Stand by for [garble].

125:53:32 Armstrong (onboard): Right, that's what we've got.

125:53:39 Aldrin (onboard): [Garble.]

125:53:51 Evans: Columbia, Houston. Heard you talking to Eagle? I assume you have comm with Eagle now? [Long pause.]

125:54:49 Collins: [Garble.]

125:55:12 Collins: [Very weak.] Houston, Columbia. Over. [No answer.]

125:55:29 Collins: [Very weak.] Houston, Columbia in Omni D Delta. Over. [No answer.]

125:56:11 Collins: [Very weak.] Houston, Columbia. Over.

125:56:15 Evans: Columbia, Houston. You're very weak. Say again.

125:56:26 Collins: [Very weak.] Roger. Houston, Columbia. CSI nominal; no plane change. Everything's going beautifully, and the LM seems to be seeing your laser [garble].

125:56:47 Evans: Columbia, Houston. You're about one-by, I could just barely make you out. I can't understand. [Pause.]

125:57:06 Collins: [Very weak.] Houston, Columbia. How now? [No answer.]

125:57:22 Collins: [Very weak.] Houston, Columbia. Over. [No answer.]

125:57:38 Collins: [Very weak.] Houston, Columbia. Over. [No answer.]

125:58:12 Collins: [Very weak.] Houston, Columbia. Over. [No answer.]

125:58:24 Aldrin: Houston, this is Eagle. Over.

125:58:27 Evans: Hey, Eagle, Houston. Loud and clear. Columbia was very weak. We were unable to read him.

125:58:36 Aldrin: Roger. We saw you come up over the horizon and it looks like you had a laser operating. Could you confirm that?

[Aldrin means the Earth rising over the horizon, and he is asking whether a laser was being fired at the Moon as part of an experiment also undertaken earlier in the mission. It would be used to target the reflector they had left on lunar surface the previous day.]
125:58:46 Evans: Eagle, Houston. Stand by. We'll check it. And, Eagle, Houston. Can you give us a burn report? [Pause.]

125:59:00 Aldrin: Roger. Stand by. [Long pause.]

125:59:24 Aldrin: Okay. The CSI burn was on scheduled time of 125:19:34.70, 51.5 feet per second was our solution. After chasing residuals a little bit, we ended up with a minus 0.2, plus 0.7, and minus 0.1. And in the AGS, at that time, we had plus 0.4, plus 0.9, and plus 0.3.

125:59:57 Evans: Eagle - Eagle, Houston. We copy. Any plane change? Over.

126:00:04 Aldrin: No. There was no plane change on CSI, and CSM had a 2.3 foot per second burn. We had a 2.9, and we elected to postpone that. Over.

126:00:18 Evans: Roger. We copy, Eagle. Thank you. [Pause.]

126:00:28 Collins: [Very weak.] Houston, how do you read Columbia now? [No answer.]

126:00:41 Collins: [Very weak.] Eagle, how about asking them for some High Gain angles for me, will you, please?

126:00:46 Aldrin: Roger, Houston, do you have some High Gain angles for Columbia? Over.

126:00:54 Evans: Roger, Eagle. And, Columbia, stand by. We'll have them for you shortly. [Long pause.]

126:01:15 Evans: Eagle, Houston. Could you verify you switched lithium hydroxide canisters? Over.

126:01:24 Aldrin: That's affirmative. We started getting an erratic indication on primary, so we switched to secondary, and it was again erratic, and I thought it might have been a sensor. But it's settled down now, and we're on the secondary. Over.

126:01:38 Evans: Roger. We copy. Mighty fine. [Pause.]

126:01:47 Evans: Columbia and Eagle. Request Omni Delta for Columbia.

126:01:57 Collins: [Very weak.] Roger, Houston. I've been in Delta the whole time but it doesn't seem to be [garble].

126:02:09 Armstrong: Houston. Columbia's been on Delta, but he hasn't had much luck with you.

126:02:18 Evans: Eagle, Houston. Roger. We copy.

[Comm break.]

[MP3 audio file. 2,587 kB.]

126:03:20 Collins: [Very weak.] Eagle, are you ready to copy [garble].

126:03:30 Collins: [Very weak.] Okay, your CDH [garble] 45 [garble] 0.2. [Long Pause.]

PAO: This is Apollo Control. Columbia's now in an orbit measuring 56.6 nautical miles [104.8 km] by 62.5 nautical miles [115.8 km], and the displays here in Mission Control show the range from Eagle to Columbia a tad over 100 miles [185 km]. And about 99 feet per second [30.2 m/s] closure rate.

126:04:25 Evans: Eagle, Houston. At your convenience, we'd like to go ahead and try your lithium hydroxides on the primary and let us take a look at it down here. [Long pause.]

126:05:04 Evans: Columbia, Houston. Over.

126:05:09 Collins: [Very weak.] Go ahead, Houston. [No answer.]

126:05:31 Collins: [Very weak.] Eagle, Tell them [garble] loud and clear since AOS [garble].

126:05:39 Armstrong: Houston, Eagle. Columbia's been reading you loud and clear on his Omnis, but he hasn't had any luck at transmitting to you.

126:05:50 Evans: Roger, Eagle. Mighty fine. We don't hear Columbia though.

126:06:00 Armstrong: Okay.

[Comm break.]

[MP3 audio file. 7,730 kB.]

126:07:27 Collins: [Very weak.] [Garble] burning [garble] at this point?

126:07:32 Aldrin: We're burning ours, Mike. Minus 1.8. [Long pause.]

126:08:32 Evans: Eagle, Houston. At your convenience [garble].

126:08:40 Evans: Columbia, Houston. At your convenience you can go to Reacq [garble] on the High Gain [garble].

126:08:56 Collins: [Very weak.] [Garbled.] [Long pause.]

126:09:42 Evans: Columbia, Houston. Over.

126:09:49 Collins: [Very weak.] [Garbled.]

126:09:59 Evans: Columbia, Houston. You can go ahead and go to Reacq in the High Gain. We should get you then.

126:10:12 Collins: [Very weak.] [Garbled.]

126:10:16 Aldrin: Do you have some angles for him, Houston?

126:10:18 Evans: Roger. Pitch minus 30, yaw 180, for Columbia.

126:10:29 Collins: [Very weak.] Copy. Thank you.

126:10:30 Aldrin: Okay. And what was your CSI - CDH solution, Mike?

126:10:35 Collins: [Very weak.] [Garble] 44 [garble] .6. Correction [garble] .4 and 14.6. Over.

126:11:18 Aldrin: Rog. Copy. Thanks. [Long pause.]

126:11:31 Armstrong: And, Houston, Eagle. Got an ECS light and a CO2 light. Partial pressure's reading about one-half millimeter.

126:11:42 Evans: Eagle and Columbia, Houston. Roger. We copy. [Long pause.]

126:12:03 Collins: Houston, how do you read Columbia now?

126:12:08 Evans: Columbia, Houston. Go. [Long pause.]

126:12:22 Evans: Eagle, Houston. We're sure that's a sensor problem. You can leave it on Primary.

126:12:30 Armstrong: Okay. [Pause.]

126:12:41 Armstrong: Roger. We pulled the circuit breakers.

126:12:45 Evans: Roger, Eagle. [Long pause.]

126:13:01 Armstrong: And our water separator apparently isn't working too well. We're getting a lot of water through the suit loop, and we've changed water separators, but it doesn't seem to have improved the situation any. [Pause.]

126:13:20 Evans: Eagle, Houston. Roger. We copy. [Long pause.]

126:13:47 Collins: Eagle, Columbia. Standing by to back you up on the burn. Just let me know how it's going.

126:13:53 Armstrong: Okay.

126:13:58 Aldrin: Okay. You want to know what our Noun 81 is?

126:14:03 Collins: Ready to copy.

126:14:05 Aldrin: Okay. I think you already got the burn time - minus 8.1, minus 1.8, minus 18.2.

126:14:19 Collins: Okay. That's pretty close agreement. And, for burn time, I still have 126:17:46.

126:14:26 Aldrin: Rog. [Long pause.]

126:15:06 Evans: Eagle, Houston. For a warm feeling, we're - we are agreeing with your CDH.

126:15:15 Aldrin: Congratulations. [Long pause.]

126:15:28 Aldrin: Unfortunately, the chart doesn't agree with it, because the range-rate at 36 minutes was off the chart.

[MP3 audio file. 5,278 kB.]

PAO: Apollo Control here. Less than a minute remaining until the Constant Delta Height or CDH maneuver. We'll continue to monitor the air-ground. This a small magnitude radial burn to put Eagle in a orbit that's concentric with - Here we go. Thirty seconds.

126:17:18 Collins: Thirty seconds.

126:17:20 Armstrong: We're ready to burn. [Pause.]

126:17:21 Collins: Okay. [Pause.]

126:17:31 Collins: Yeah. I'm ready. Okay.

[Comm break.]
126:18:49 Collins: Burn complete?

126:18:51 Armstrong: Burn complete.

126:18:52 Collins: Thank you. [Long pause.]

126:19:47 Evans: Eagle, Houston. When you get a chance, are your LCGs hooked up? And if so, what does the LCG accumulator show? [Long pause.]

PAO: This is Apollo Control. Range now showing 91.3 nautical miles [169.1 km]. Range-rate, rate of closure, 119 feet per second [36 m/s].

126:20:37 Collins: Eagle, Columbia. Passing over the Landing Site. It sure is great to look down there and not see you.

126:20:45 Armstrong: Okay. [Long pause.]

126:21:04 Evans: Eagle, Houston.

126:21:08 Armstrong: Go ahead.

126:21:09 Evans: Roger. Did you copy on the LCG, there, and the reading on the water accumulator?

126:21:15 Armstrong: Yeah. Roger. I did. I'm getting [garble].

[Comm break.]
126:22:20 Aldrin: Houston, the water accumulator is right on the line between the red and the green. Over.

126:22:26 Evans: Eagle, Houston. Roger. We copy.

126:24:13 Evans: Eagle, Houston.

126:24:19 Aldrin: Houston, Eagle.

126:24:20 Evans: Roger. On the water problem there, we can't add anything more to it, except the fact that it looks like the water accumulators are up to speed, to us down here.

126:24:35 Armstrong: Okay. It's not going to be too much trouble.

126:24:39 Evans: Roger. Fine.

126:24:40 Aldrin: It's just in one suit, too, for some reason.

[Comm break.]
126:26:29 Evans: Columbia, Houston. Our comm problem was traced to a ground station here.

126:33:25 Aldrin: You're about 32 seconds later than we are.

126:33:29 Collins: Okay, fine.

[Comm break.]
PAO: This is Apollo Control. Some 25 minutes now until the TPI, Terminal Phase Initiation burn, just before Loss Of Signal as both spacecraft go over the hill.

126:35:01 Aldrin: [Garble.]

[Long comm break.]
PAO: This is Apollo Control. The Black Team of flight controllors here in Mission Control are more or less in an advisory capacity during this rendezvous sequence. They're actively computing maneuver times, but in the final analysis, it's onboard computations by the crew of Columbia and Eagle which really bring about the rendezvous. Standing by at 126 hours, 37 minutes Ground Elapsed Time; some 24 minutes away from ignition on the thrust along the line of sight for Terminal Phase Initiate.

126:44:25 Aldrin: We haven't settled on a final one yet. The last one was - stand by. [Long pause.]

126:45:04 Collins: Roger. Understand. [Pause.]

126:45:12 Collins: Just as soon as you know what TPI TIG's going to be, I'd appreciate a call.

126:45:18 Aldrin: Okay.

126:45:24 Collins: Last I got was 32 seconds earlier than mine which would make it 127:02:02. [Pause.]

126:45:40 Collins: Thank you. Are you going to be revising that one?

126:45:44 Aldrin: I think probably so. How late - How late can you take a revision? [Pause.]

126:45:56 Collins: Well, to stay on my time line, I should have it in the next couple of minutes.

126:48:07 Aldrin: Okay. Latest estimate, 127:03:39.

126:48:14 Collins: Thank you kindly. [Long pause.]

126:48:41 Evans: Eagle, Houston.

126:48:45 Aldrin: Roger. Go ahead.

126:48:47 Evans: Roger. In the event of the possibility that we may have had some water channeling in those hydroxide canisters, we recommend you stay in the cabin mode from now on. Over.

126:51:25 Evans: Eagle, Houston.

126:51:30 Aldrin: Go ahead.

126:51:32 Evans: Roger. I'd better clarify that cabin mode a little bit there. What we mean is you go ahead and stay in the cabin mode. Helmets and gloves on are your option. And we really have no concern with the CO2. Over.

126:51:52 Aldrin: Roger. Understand. [Long pause.]

126:52:51 Aldrin: Mike, you already loaded that time? We've got a final one here.

126:52:58 Collins: I've already loaded it. I don't think it'll make much difference.

126:53:01 Aldrin: Roger. Only 9 seconds difference.

126:53:04 Collins: Mox nix.

[Mox nix is attributed to the German idiom, macht nichts, meaning 'it doesn't matter'.]
126:54:06 Evans: Columbia, Houston.

126:54:12 Collins: Columbia. Go ahead.

126:54:13 Evans: Roger, Mike. You can go ahead and arm your logic anytime you want to, and we'll give you a Go so that you can get your Pyro Arm at your convenience.

126:54:23 Collins: That's a good idea, babe. You standing by to watch the logic?

126:54:26 Evans: Affirmative. Give us a Mark.

126:54:30 Collins: Mark, Logic 1.

126:54:32 Collins: Mark, Logic 2. [Long pause.]

126:54:59 Evans: Columbia, Houston. We need the SECS Arm circuit breakers closed.

126:55:08 Collins: Okay. Going in SECS Arm Batt A, and Batt B. [Long pause.]

126:55:27 Evans: Columbia, Houston. Logic looks good. You can arm your Pyros at your convenience.

126:55:36 Collins: Thank you. [Long pause.]

127:02:32 Collins: Coming up on 1 minute to TIG, Neil. How's it looking?

127:02:38 Armstrong: Pretty good.

127:02:40 Collins: Good.

127:02:43 Armstrong: That out-of-plane was in the AGS, not in the radar.

127:03:52 Armstrong: We're burning.

127:03:54 Collins: Atta-boy! [Long pause.]

127:04:32 Armstrong (onboard): Okay, that's it.

127:04:34 Collins: Burn complete?

127:04:35 Armstrong (onboard): Burn's complete. Did you... [air-ground] read? Burn complete.

127:04:42 Collins: Roger. Thank you.

127:04:43 Evans: Eagle, Houston. Aft Omni, low-bit rate, and we'll see you at 127 plus 51.

127:05:07 Aldrin (onboard): Okay, [garble] 5, huh?

PAO: This is Apollo Control. We've apparently had Loss Of Signal with Columbia and Eagle as they went behind the Moon on the 26th revolution. Next maneuver scheduled for about 33 minutes from now. While both vehicles are behind the Moon, this will be the braking series of maneuvers coming down to docking, or station-keeping first, and then docking at about 128 hours Ground Elapsed Time. And at 127 hours, 6 minutes Ground Elapsed Time in the flight of Apollo 11; this is Mission Control.

127:06:10 Armstrong (onboard): Well - say when [garble] Oh, wait a minute.

127:06:50 Aldrin (onboard): Chart at 26/7 forward for...

127:06:55 Armstrong (onboard): Pretty reasonable.

127:06:59 Aldrin (onboard): AGS had these residuals after its completion after the burn.

127:07:39 Armstrong (onboard): I can't see you, Michael.

127:07:44 Collins (onboard): [Garble] moving in at [garble].

127:07:50 Armstrong (onboard): Okay. I got good radar. I just can't see you.

127:08:03 Collins (onboard): [Garble.]

127:08:49 Aldrin (onboard): Do you think that pressure dropped?

127:08:51 Armstrong (onboard): Yes.

127:08:54 Aldrin (onboard): It doesn't show up in the [garble] books. I don't see any reason why we don't take them all back. All that we've got [garble].

127:09:00 Armstrong (onboard): All got data.

127:09:02 Aldrin (onboard): We all got something [garble].

127:10:20 Aldrin (onboard): Okay, you try getting it - [garble]?

127:10:25 Armstrong (onboard): No, I haven't been. Do you want me to?

127:10:27 Aldrin (onboard): No, I got to keep the chart.

127:10:58 Armstrong (onboard): [Garble] can take this update for them.

127:12:00 Aldrin (onboard): On the track about, huh?

127:12:21 Aldrin (onboard): Boy, my shoulders sure hurt.

127:12:23 Armstrong (onboard): Mine are, too.

127:12:26 Aldrin (onboard): Last night I couldn't get this far from the [garble].

127:12:30 Armstrong (onboard): I was the same way.

127:13:00 Aldrin (onboard): Use all the green tape, did you?

127:14:31 Armstrong (onboard): I got it in sight now, Mike.

127:14:34 Collins (onboard): [Garble.]

127:15:33 Aldrin (onboard): [Garble.]

127:15:39 Armstrong (onboard): Okay.

127:16:18 Aldrin (onboard): Yes, so do we.

127:16:19 Armstrong (onboard): A hundred and what?

127:16:33 Collins (onboard): [Garble.]

127:16:37 Aldrin (onboard): Okay, Noun 81, minus 0, plus 0.4, plus 0.9.

127:16:49 Collins (onboard): And now [Noun?], plus 0.4, plus 0.9. [Garble.]

127:16:58 Aldrin (onboard): And 15 minutes after TPI, I've got...

127:17:03 Collins (onboard): [Garble.]

127:17:35 Armstrong (onboard): M-1.

127:17:36 Aldrin (onboard): [Garble.]

127:17:53 Aldrin (onboard): [Garble] your burn's a little late.

127:18:04 Armstrong (onboard): [Garble] be burning - [garble].

127:18:12 Aldrin (onboard): Okay, [garble] the [garble] on? There it is.

127:18:28 Aldrin (onboard): Neil, I guarantee you that the burn is precise, okay?

127:18:31 Armstrong (onboard): [Garble.]

127:18:33 Aldrin (onboard): Good.

127:18:39 Collins (onboard): [Garble] good burn [garble].

127:18:43 Armstrong (onboard): No, it's not going to be late. Maybe 5 seconds.

127:19:17 Armstrong (onboard): Burn complete.

127:19:19 Collins (onboard): Thank you.

127:20:13 Armstrong (onboard): Well, it's all over but the docking.

127:20:26 Armstrong (onboard): Check the start out there.

127:20:32 Aldrin (onboard): Okay.

127:20:41 Armstrong (onboard): [Garble.]

127:20:51 Aldrin (onboard): You still got him?

127:20:55 Armstrong (onboard): Yes. I probably won't when the sun gets in my telescope.

127:21:06 Aldrin (onboard): [Garble.] [Garble] hold the [garble].

127:21:11 Collins (onboard): Now I can't see...

127:21:13 Armstrong (onboard): The what?

127:21:14 Aldrin (onboard): Won't hold the [garble].

127:21:19 Collins (onboard): [Garble] going right down the [garble] and it sure has been nice.

127:21:23 Armstrong (onboard): Okay. I just got sight of you in the sunlight here.

127:21:27 Collins (onboard): Okay.

127:21:29 Aldrin (onboard): Oh, I've got him.

127:21:43 Aldrin (onboard): [Garble.]

127:21:51 Armstrong (onboard): I've got him now, too.

127:22:00 Aldrin (onboard): Sure enough.

127:22:11 Collins (onboard): Well, I see you don't have any landing gear.

127:22:15 Armstrong (onboard): That's good.

127:22:19 Collins (onboard): [Garble.]

127:22:27 Armstrong (onboard): You're not confused on which end to dock with, are you?

127:22:34 Collins (onboard): [Garble.]

127:22:58 Armstrong (onboard): Okay, Mike, if there's some data bags around there - I may have one or two in my temporary stowage - why, we may want them in addition to the other regular bags, so we can put some of this data back in it.

127:23:13 Collins (onboard): In the data bags?

127:23:16 Armstrong (onboard): Yes, there are a couple of different LM bags that I left in there.

127:23:21 Collins (onboard): Okay, well, why don't we [garble] back over there and [garble]?

127:23:26 Armstrong (onboard): Right.

127:23:39 Collins (onboard): [Garble] bring the bag [garble].

127:23:45 Armstrong (onboard): Could be.

127:23:47 Collins (onboard): Alright.

127:24:13 Collins (onboard): Okay, [garble] have a plastic one and a [garble].

127:24:23 Collins (onboard): Bring the [garble] back.

127:24:40 Armstrong (onboard): I think we'll make it (laughter).

127:24:44 Aldrin (onboard): Don't tell that to poor [garble], though (laughter).

127:24:47 Collins (onboard): [Garble.]

127:24:56 Armstrong (onboard): We'll see you at [garble].

127:25:02 Armstrong (onboard): Okay.

127:25:31 Armstrong (onboard): One of those two bright spots is bound to be Mike.

127:25:36 Aldrin (onboard): How about picking the closest one?

127:25:44 Armstrong (onboard): Good idea.

127:26:17 Aldrin (onboard): [Garble] this light?

127:26:21 Armstrong (onboard): Is that alright?

127:26:37 Armstrong (onboard): Okay, at 49,000 feet [15,000 metres], we're supposed to be 65 feet per second [20 m/s] - our little old chart says. And our LOS rate's supposed to be about 0.1. It's about point...

127:26:51 Collins (onboard): [Garble.]

127:26:55 Aldrin (onboard): Okay.

127:27:08 Collins (onboard): [Garble.]

127:27:16 Armstrong (onboard): Right - that's [garble].

127:27:26 Aldrin (onboard): 12 on here, right?

127:27:29 Armstrong (onboard): Not exactly.

127:27:30 Aldrin (onboard): Not exactly?

127:27:32 Armstrong (onboard): You're a little less. You're 10 seconds less in [garble]. About that [garble].

127:28:23 Armstrong (onboard): Look's like you're making a high [garble] on us, Michael.

127:28:27 Collins (onboard): Yes, [garble].

127:29:26 Collins (onboard): [Garble] let me move in just a [garble].

127:29:31 Armstrong (onboard): No, we aren't that - confident.

127:30:08 Armstrong (onboard): [Garble]?

127:30:12 Aldrin (onboard): We've got about 54.

127:30:47 Armstrong (onboard): You got [garble] to [garble]?

127:30:49 Aldrin (onboard): Huh?

127:30:50 Armstrong (onboard): The [garble]?

127:30:51 Aldrin (onboard): Yes. [Garble].

127:31:05 Armstrong (onboard): Let's try this midcourse out.

127:31:08 Aldrin (onboard): Right. Okay, it's [garble].

127:31:37 Aldrin (onboard): [Garble].

127:31:40 Armstrong (onboard): Is that right, I hope?

127:31:42 Aldrin (onboard): Yes.

127:31:59 Armstrong (onboard): It should be 70.

127:32:25 Aldrin (onboard): Okay, I can see the shape of your vehicle now, Mike.

127:32:42 Armstrong (onboard): Oh, yes - got your High Gain in sight, your tracking light - whole vehicle shows. I see that you're pointed at me. Now, you're turning a little bit - great.

127:33:39 Collins (onboard): [Garble].

127:33:49 Collins (onboard): Are you burning yet?

127:33:50 Armstrong (onboard): We're burning.

127:33:51 Collins (onboard): [Garble].

127:34:15 Aldrin (onboard): Good enough.

127:34:21 Armstrong (onboard): Seems like when you get down to around 110, you just keep chasing him. You put it in - stick it in one axis, and it goes through - out of another, especially when [garble] stays about the same.

127:34:30 Aldrin (onboard): If it's [garble], it's definite.

127:34:43 Aldrin (onboard): Okay, now, let's see. We want to change the DAP - that what we want to do?

127:34:48 Armstrong (onboard): Yes.

127:34:49 Collins (onboard): I need a P76 now, Buzz.

127:34:54 Aldrin (onboard): Okay, you got the time for the burn. Noun 81 was plus 0.1, plus 1.2, plus 0.5.

127:35:05 Collins (onboard): [Garble].

127:35:23 Aldrin (onboard): [Garble] plus [garble].

127:35:38 Armstrong (onboard): Okay. [Garble] 45...

127:36:14 Armstrong (onboard): 8.2 miles [15.2 km], 40 feet per second [12.2 m/s].

127:36:26 Aldrin (onboard): You can have your place now.

127:36:49 Collins (onboard): [Garble].

127:36:52 Armstrong (onboard): Okay.

127:37:01 Aldrin (onboard): Can you see our tracking light, now?

127:37:04 Collins (onboard): [Garble] but you're in between my sextant and my COAS.

127:38:33 Aldrin (onboard): Where'd you put the [garble]?

127:38:35 Armstrong (onboard): My what?

127:38:36 Aldrin (onboard): Your [garble] for [garble].

127:38:39 Armstrong (onboard): It's in the bottom over [garble].

127:39:30 Collins (onboard): [Garble] pick me up [garble].

127:39:33 Armstrong (onboard): I got you.

127:39:34 Collins (onboard): Okay. Don't [garble] other spacecraft.

127:39:40 Aldrin (onboard): No, I'm not going to lose you, brother.

127:39:49 Collins (onboard): What have you got for [garble]? [Garble] I have 6.8 and 9 miles, [garble] out. Oh, that checks.

127:40:06 Armstrong (onboard): Got [garble] up? I thought I made it pretty clear.

127:40:20 Aldrin (onboard): Not as sporty a [garble] as we thought, huh?

127:40:25 Armstrong (onboard): That wasn't - bad at all. The alignment was - pretty dicey.

127:40:31 Aldrin (onboard): Yes, sir.

127:40:34 Armstrong (onboard): That was just luck (laughter).

127:40:39 Aldrin (onboard): I hope you [garble].

127:40:49 Aldrin (onboard): I'll be glad to get to the [garble].

127:40:52 Armstrong (onboard): Yes, but I hate to [garble]; will you get [garble]?

127:40:57 Aldrin (onboard): Okay.

127:41:02 Armstrong (onboard): Oh, it'll come off, I guess - [garble].

127:41:07 Aldrin (onboard): These screws here...

127:41:08 Armstrong (onboard): Alright, there's a couple of bolts...

127:41:10 Aldrin (onboard): ...these screws here might do it.

127:41:13 Armstrong (onboard): ...there's a couple of bolts down there that have come loose - if I remember. [Garble] I'll get them.

127:41:21 Collins (onboard): I'm slowly closing at 32 feet per second [10 m/s] and a mile-and-a-half [2.8 km].

127:41:25 Armstrong (onboard): Okay, I've got a mile-and-a-half and 32½.

127:41:28 Collins (onboard): [Garble].

127:41:40 Aldrin (onboard): Take [garble].

127:41:43 Armstrong (onboard): Yes, I guess it'll take us another - 6 minutes or something like that.

127:41:47 Aldrin (onboard): Yes.

127:41:48 Collins (onboard): [Garble] we got 15 [garble].

127:41:57 Collins (onboard): [Garble].

127:42:01 Armstrong (onboard): Okay.

127:42:23 Aldrin (onboard): That's going to hit the braking gate right on the schedule.

127:42:30 Armstrong (onboard): Yes.

127:43:02 Armstrong (onboard): Okay, let's put P47 in.

127:43:22 Armstrong (onboard): I don't know why I lost my - I'm at - oh, did you - you lost your transponder, Mike - I think.

127:43:33 Collins (onboard): [Garble] pitch up a bit.

127:43:36 Armstrong (onboard): I wish you would.

127:43:43 Collins (onboard): I have 0.7 mile [1.3 km] and I got you at 31 feet per second [9.5 m/s], [garble] look good.

127:43:50 Aldrin (onboard): Okay, [garble].

127:43:53 Collins (onboard): [Garble]?

127:43:57 Aldrin (onboard): Okay, we're getting it.

127:43:59 Collins (onboard): [Garble]...

127:44:12 Collins (onboard): Are you [garble] forward now?

127:44:15 Aldrin (onboard): Yes - yes, we're in good shape, Mike. We're braking.

127:44:17 Collins (onboard): Okay.

127:44:52 Collins (onboard): [Garble].

127:44:53 Armstrong (onboard): Flying all over us.

127:46:13 Armstrong (onboard): Okay, we're about 11 feet a second [3.4 m/s] coming in at you.

127:46:17 Collins (onboard): [Garble].

127:46:43 Collins (onboard): That's good. What [garble] are you in?

127:47:05 Aldrin (onboard): Hope we're not going to get a pitch straight down.

127:47:16 Armstrong (onboard): We've got a - pitchdown and then a yaw to do...

127:47:55 Collins (onboard): [Garble].

127:47:59 Armstrong (onboard): Looks good.

127:49:06 Collins (onboard): I'm sure you're going to get [garble], I'll tell you that.

127:49:11 Armstrong (onboard): It flies good, though.

127:49:16 Collins (onboard): [Garble]?

127:49:50 Armstrong (onboard): Okay, now, if I pitch over, I'm going to be looking right into the Sun.

127:50:00 Collins (onboard): [Garble].

127:50:09 Aldrin (onboard): Hope you know how to roll.

127:50:11 Collins (onboard): Yes, I do. I [garble].

[MP3 audio file. 6,984 kB.]
PAO: This is Apollo Control; 127 hours, 50 minutes Ground Elapsed Time. Less than a minute now away from acquisition of the spacecraft, Columbia. Hopefully flying within a few feet of it, will be Eagle. Docking should take place about 10 minutes from now, according to the Flight Plan. However, this is a crew option matter. We're standing by for word that data is coming in from the two spacecraft.

127:50:23 Aldrin (onboard): You want to end up with that window - opposite his right window so you don't want to roll right. Right?

127:50:32 Armstrong (onboard): Yes.

127:50:34 Aldrin (onboard): The only trouble is, it's towards - towards 90, isn't it?

127:50:56 Aldrin (onboard): You could - you...

127:50:58 Armstrong (onboard): If I roll 120 - it'll roll left

127:51:06 Aldrin (onboard): 90, huh? [Garble] 60?

PAO: This is lunar revolution number 27 for Columbia.

127:51:21 Armstrong (onboard): Well, why don't I start to roll...

127:51:24 Aldrin (onboard): Yes, I think if you roll up 60...

127:51:29 Armstrong (onboard): I'll be looking into his left window when I pitch up.

127:51:32 Aldrin (onboard): I don't think so. If you did it right now you'd...

127:51:36 Collins (onboard): [Garble] I got the Earth coming up already. It's fantastic!

Mike was particularly pleased with the fact that he had managed to get all four players in the story into one image; Earth, Moon, Eagle and with the edge of the Command Module's window visible, Columbia.]


127:51:42 Armstrong: Okay. You've got me.

127:52:00 Evans: Eagle and Columbia, Houston. Standing by.

127:52:05 Armstrong: Roger. We're station-keeping.

127:52:08 Evans: Roger.

127:52:24 Aldrin (onboard): Pitch up [garble] pass right up just a little, you got a better view - bottom side - [garble] - move back.

127:52:45 Collins (onboard): [Garble] - that's right.

127:53:08 Armstrong (onboard): Okay. I'm getting about into the right attitude, I think. [Garble].

127:53:18 Aldrin (onboard): Yes.

127:53:21 Armstrong (onboard): That roll's pretty far. I don't know just how much - so that's - Oh, it's going to go Block!

127:53:28 Aldrin (onboard): That's it - going to AGS?

127:53:32 Armstrong (onboard): Yes, [garble] Att Deadband.

127:54:11 Armstrong: Okay, Mike, I'll get - try to get in position here, and then you got it.

127:54:18 Collins (onboard): Okay.

127:54:39 Armstrong: How does the roll attitude look?

127:54:41 Collins (onboard): [Garble].

127:54:47 Armstrong (onboard): Let's see how the DSKY thinks it looks.

127:54:52 Collins (onboard): Have you stopped rolling yet?

127:54:54 Armstrong: I'll stop. Matter of fact, I can stop right here, if you like that.

127:54:59 Collins (onboard): Need a little bit more. That's the way, keep it going. Need a little more [garble]. That's the way, keep going - go a little bit more - go ahead - go ahead - okay, stop. Okay, I got it now.

127:55:27 Aldrin (onboard): You got the [garble] in [garble]?

127:55:36 Armstrong (onboard): Yes. Right there. Okay, [garble] I...

127:55:55 Aldrin (onboard): Well, we might need to at least have a platform [garble].

127:56:01 Armstrong (onboard): Yes.

127:56:27 Collins (onboard): Okay, now, Neil, when you feel us contact, you're going to turn [garble] seconds, is that right?

127:56:30 Evans: Eagle, Houston. Middle gimbal. And you might pass to Columbia, we don't have him yet.

127:56:33 Armstrong: That's right.

127:56:34 Collins (onboard): Okay, Buzz.

127:57:12 Aldrin (onboard): We got a platform to make.

127:57:13 Armstrong (onboard): Okay.

127:57:34 Armstrong: I'm not going to do a thing, Mike. I'm just letting her hold in Attitude Hold.

127:57:39 Collins: Okay.

127:57:55 Armstrong (onboard): I think we ought to be at 4 jets for this, [garble] AGS.

127:58:04 Aldrin (onboard): Hold.

127:58:13 Armstrong (onboard): [Garble].

127:58:42 Armstrong (onboard): He's about 15 feet out now.

127:58:45 Aldrin (onboard): Okay, I'd better try out the radar.

127:58:52 Armstrong (onboard): Don't you want to beef up that radar?

127:58:59 Aldrin (onboard): Yes.

127:59:00 Armstrong (onboard): Good.

127:59:06 Armstrong (onboard): Ready to pull the circuit breakers?

127:59:08 Aldrin (onboard): Okay. You ready?

127:59:10 Armstrong (onboard): Yes.

127:59:12 Aldrin (onboard): They're pulled.

127:59:14 Armstrong (onboard): He's 10 feet. About 5 feet, I guess.

127:59:23 Armstrong (onboard): Looks good, Mike.

127:59:35 Aldrin (onboard): Okay, they're pulled.

127:59:39 Armstrong (onboard): Pull it out.

127:59:40 Aldrin (onboard): Okay. Circuit breakers...

[MP3 audio file. 4,361 kB.]
128:00:50 Armstrong: You [garble].

128:00:56 Armstrong: Okay.

[Comm break.]
128:02:14 Armstrong: Go ahead. [Long pause.]

128:02:46 Armstrong: [Garble]. [Long pause.]

128:03:12 Armstrong: Okay. We're all yours, Columbia.

128:03:17 Collins: Okay. [Pause.] Okay, I have thrusters B3 and C4 safetied.

128:03:30 Armstrong: Okay. [Long pause.]

128:03:43 Collins: I'm pumping up cabin pressure. [Long pause.]

128:04:29 Collins: That was a funny one, you know. I didn't - I didn't feel a shock, and I thought things were pretty steady. I went to Retract there, and that's when all hell broke loose. [Pause.] Were you guys - did it appear to you to be - that you were jerking around quite a bit during the retract cycle?

128:04:50 Armstrong: Ah yeah. It seemed to happen at the time I put the plus-X thrust to it, and apparently it wasn't centered, because somehow or other I accidentally got off in attitude and then the attitude hold system started firing.

128:05:09 Collins: Yeah. I was sure busy there for a couple of seconds. [Pause.]

128:05:19 Collins: Are you hearing me all right? I got a horrible squeal.

128:05:22 Armstrong: Yeah. I agree with that, but we hear you okay.

[Apollo 11 has re-emerged from the far side of the Moon on the 27th orbit as a single docked spacecraft, no longer using the separate call signs of Columbia and Eagle.]
