Apollo 11

Day 1, part 4: Navigation and Housekeeping

Corrected Transcript and Commentary Copyright © 2009 by W. David Woods, Kenneth D. MacTaggart and Frank O'Brien. All rights reserved.

[Apollo 11 is now a complete spacecraft, the Command Module docked to the Lunar Module which was extracted from its launch position atop the last stage of the Saturn V launch vehicle. The joined craft have safely maneuvered away from the abandoned stage, which has been sent on a path towards solar orbit. Now the crew settle down to some navigation tasks, general house-keeping and eating. They make a television transmission of views of the Earth from their window before retiring for the night.]

006:09:31 Collins: Thank you very much. And we're about to take our marks, Charlie, on this P23 optics Cal. I've got it in the sextant now, and I'm about to split the image and Mark.

006:09:42 Duke: Roger, Mike. We're watching.

PAO: The CapCom is now Charlie Duke, and Gene Kranz and his White Team of flight controllers is preparing to take over the responsibility here in the Control Center from Cliff Charlesworth's team.

PAO: This is Apollo Control at 6 hours, 16 minutes into the mission. Velocity now 11,479 feet per second. Apollo 11's distance from Earth, 27,938 nautical miles. We're estimating the change of shift news conference for 3:30 pm Central Daylight Time.

006:19:23 Duke: Hello, Apollo 11. Houston. We have scrubbed the Midcourse 1. Over.

006:19:30 Collins: Roger. Understand you've scrubbed Midcourse 1.

006:19:33 Duke: Rog.

006:21:39 Duke: Hello, Apollo 11. Houston. We see your middle gimbal angle getting pretty big. Over.

006:21:45 Collins: Well, it was, Charlie, but in going from one Auto maneuver to another, we took over control and have gone around gimbal lock; and we're about to give control back to the DAP.

006:21:56 Duke: Roger, Mike. We see it increasing now.

006:25:25 Aldrin: Hey, Charlie.

006:25:45 Aldrin: Houston, Apollo 11.

006:25:46 Duke: Go ahead, 11. Over.

006:25:47 Aldrin: Hey, maybe you better call Lew and tell him we might be a little bit late for dinner.

[In the final weeks before launch, the crew had stayed at crew quarters at KSC. Their food was served up by Lew Hartzell, a former tug-boat cook who catered for all the Apollo crews.]

006:26:08 Collins: We recalled the program.

006:26:12 Duke: Roger.

006:26:13 Collins: And O₂ fan number 2 is on.

006:26:15 Duke: Rog.

006:26:42 Aldrin: Houston, Apollo 11. [I've] got a Cryo pressure light and a Master Alarm. It's re-set.

006:26:51 Duke: Ah, Roger. We expected that. That's why we had you turn the fan on. We were getting pretty close to the caution and warning limits. We were trying to prevent that.

006:27:00 Aldrin: Okay.

PAO: This is Apollo Control at 6 hours, 31 minutes. At the present time the spacecraft is 29,363 nautical miles from Earth and the velocity continuing to drop off gradually, reading now 11,192 feet per second. Flight Director Gene Kranz has taken over as Flight Director now from Clifford Charlesworth. Kranz has been reviewing the status of the spacecraft's systems with his team of flight controllers; everything looks very good at this point. The crew has been advised that the Midcourse Correction 1, the first opportunity for a midcourse correction, of which has been scheduled into the Flight Plan at about 13 hours, 30 minutes, will not be performed. Ah, correction. A midcourse had been scheduled at 11 hours, 45 minutes into the Flight Plan and that will not be performed according to the tracking data we have at this time. The crew, up until their sleep period, which will begin at about 13 hours, 30 minutes or about 7 hours from now, will be involved generally in a routine of housekeeping type activities aboard the spacecraft. At the present time they should be involved in some midcourse navigations. At 6 hours, 32 minutes; this is Apollo Control, Houston.

006:34:30 Collins: Houston, Apollo 11.

006:34:36 Duke: Go ahead, 11. Over.

006:34:39 Collins: Roger. You're looking at our Delta-R/Delta-V. It looks like Delta-R is pretty large, there. We wanted to talk to you about it before we incorporate it.

006:34:44 Duke: Stand by, Mike. We don't have anything on our downlink here, I don't think, on the DSKY. Stand by.

006:34:50 Collins: Okay. Our Noun 49 is reading: register 1, plus 08793; register 2, all balls.

006:35:01 Duke: Copy.

006:36:15 Duke: 11, Houston. Guidance is looking at the Noun 40 - 49 stuff. We'll be back with you momentarily. Over.

006:36:23 Collins: Okay, Charlie. Thank you. We'll just hold right here in the program.

006:36:26 Duke: Roger. We got your downlink now. Over.

006:36:27 Collins: Okay.

006:36:57 Duke: Hello, Apollo 11. Houston. We'd like you to reject the Noun 49 stuff on the DSKY right now, Mike, and try it again. Over.

006:37:01 Collins: Okay. Will do.

006:38:46 Collins: Okay, Houston. Apollo 11. Here's another [Noun] 49 for you. Are you getting it on the downlink?

006:38:51 Duke: Roger. We see it. Stand by.

006:40:22 Duke: Hello, Apollo 11. Houston. We recommend you accept the Noun 49 display on the DSKY now. Over.

006:40:34 Collins: Okay. It looks like an awful big one. We noticed that you'd moved star number 2 to the tail end of the listing, and we should be marking first on star 40. Did that have anything to do with it?

006:40:47 Duke: Negative. We don't believe so, Apollo 11. We think that this is possibly due to some TLI dispersions, and it's probably satisfactory, so go ahead and accept this. It fits our criteria anyway that if you repeat the mark and you get an equivalent size error, to go ahead and accept it. And this is an equivalent size error. Over.

006:41:09 Collins: Okay. We'll do it.

006:41:14 Duke: And 11, Houston. Your state vector in the LM slots are - is good. Over.

006:41:22 Collins: Roger. Thank you.

006:42:55 Collins: Houston, Apollo 11. If you like this, we'll accept it as well.

006:43:00 Duke: Stand by.

006:43:46 Duke: Hello, Apollo 11. Houston. We recommend you accept the Noun 49. Over.

006:43:51 Collins: Okay, Charlie. Thank you. We'll do that now.

006:43:53 Duke: Thank you.

006:44:39 Collins: And we're going to proceed on this one, too, Charlie.

006:44:41 Duke: Roger. Copy.

006:48:35 Collins: Houston, Apollo 11. Another Noun 49 for you.

006:48:40 Duke: Rog. We copy. Stand by.

006:49:00 Duke: Hello, Apollo 11. Houston. We'd like you to recycle and do this one over again. Over.

006:49:07 Collins: Okay.

PAO: This is Apollo Control at 6 hours, 52 minutes. Apollo 11 now 31,565 nautical miles from Earth and the velocity is 10,789 feet per second. The crew, at this time, is involved in midcourse navigation using their onboard optical system. We have completed the changeover and briefing of shifts here in Mission Control, and the crew activities, until the sleep period begins, will consist of housekeeping functions aboard the spacecraft, changing out carbon dioxide filters. They will not be doing the midcourse correction scheduled for 11 hours, 45 minutes into the flight, as the first opportunity. The change of shift briefing is scheduled to begin shortly. Any conversations that develop with the crew during that period of time will be tape recorded and we'll play those back following the change of shift briefing. This is Apollo Control at 6 hours, 53 minutes.

006:53:41 Aldrin: Houston, Apollo 11.

006:53:43 Duke: Go ahead, Apollo 11. Over.

006:53:45 Aldrin: Roger. Why don't you sing out when you think we've done enough battery charging on B.

006:53:50 Duke: Rog. Stand by, Buzz. Over.

006:55:50 Duke: Hello, Apollo 11. Houston. We'll be charging battery B up until the sleep period. We'll discontinue charging at that time. Also, at about 12:25 in the Flight Plan, we have battery A charge. That has been deleted. Over.

006:56:05 Aldrin: Roger. Understand. We'll charge until the sleep period on B and delete the battery A charge.

006:56:10 Duke: Affirm.

006:56:17 Collins: And, Houston, Apollo 11. These Auto optics maneuvers or P23s, Auto maneuvers, don't seem to be going to the substellar point. Can you come up with the roll, pitch, and yaw angle for the substellar point on this star? It's our second star.

006:56:31 Duke: Roger. Stand by.

006:57:21 Duke: Hello, Apollo 11. Houston. Your angles in the Flight Plan we feel are still good; 198.6, 130.7, 340.0. Just slightly off than those in the Flight Plan. Over.

006:57:36 Collins: Okay. We'll try that.

006:58:28 Collins: Charlie, state those three angles one more time. I'd like to confirm them before I maneuver.

006:58:32 Duke: Roger. Roll and pitch are slightly off than what's in the Flight Plan, 11. Roll is now 198.6, pitch is 130.7. Over.

006:58:47 Collins: Roger. Roll 198.6, pitch 130.7, and yaw 34000 [means 340.0].

006:58:55 Duke: That's affirmative.

007:03:32 Collins: Houston, Apollo 11. I think the problem here is that that attitude just is not too close to the substellar point. I'm having to maneuver quite a bit; and that's in progress now, so stand by for some marks.

007:03:45 Duke: Roger. We copy it all.

007:09:24 Duke: Hello, Apollo 11. Houston. We've run the angles given in the Flight Plan for the P23 attitude through the machines down here, and they come up the same thing every time. We think everything's going correctly, Mike, and we're wondering if the non-symmetrical horizon might by giving a problem. Over.

007:09:51 Collins: Yeah, it could be, Charlie. Stand by here. We'll get another mark for you.

007:09:55 Duke: Okay.

007:10:30 Collins: Houston, Apollo 11. Noun 49 for you.

007:10:34 Duke: Roger. Copy.

007:10:41 Duke: Stand by.

007:11:05 Duke: Hello, Apollo 11. Houston. We recommend you accept the Noun 49. Continue through your sequence of sightings, and then we'll analyze the data afterwards. Over.

007:11:15 Collins: Okay.

PAO: This is Apollo Control; 7 hours, 21 minutes into the flight of Apollo 11. During the change of shift briefing, we accumulated about 4 minutes of taped conversation with the spacecraft. That conversation generally related to the onboard batteries, which are currently being charged - a routine operation - and also the midcourse navigation exercise that the crew is currently involved in. We'll play back the tape for you now, and then stand by for any live conversation with the crew.

007:20:56 Collins: Houston, Apollo 11. Star 40 has just disappeared now in the sextant. Could the trunnion angle 47 - something be a little high?

007:21:05 Duke: Stand by.

007:21:21 Duke: Hello, Apollo 11. Houston. We'd like you to press on to star 44. Over.

007:21:26 Collins: Yeah, Roger. How many marks have you recorded on star 40?

007:21:29 Duke: Stand by, Mike.

007:21:32 Collins: Okay.

007:21:45 Duke: 11, Houston. We copied two good marks. Over.

007:21:49 Collins: Okay.

007:33:00 Collins: Houston, Apollo 11.

007:33:01 Duke: Go ahead. Over.

007:33:03 Collins: Roger. Forty-four is just not bright enough for this. There is a reddish glow filling the black area of the sextant, and the star is lost somewhere in there, and I cannot see it.

007:33:17 Duke: Roger. Stand by. We'll come up with another star. Over.

007:33:21 Collins: Yeah. I'd appreciate that.

[Crews often found that if the Sun was impinging near the optics' apertures, it would often cause substantial flare within their optical paths. It is worth reminding ourselves how incredibly dim even the brightest stars are with respect to the Sun. Stars are virtually impossible to see when the eye is adapted to sunlight and it usually needs a period of adaptation to the dark to allow any but the bright stars to become visible.]

007:33:53 Collins: Okay.

007:33:54 Duke: And, Mike, we think these large Delta-Rs, Noun 49, you're getting is really meaningful since it's been way before TLI since we had a state vector update; and we think it's normal. Over.

007:34:09 Collins: Okay. Could be, Charlie. Some of the early markings: I might not have had precisely the substellar point. I think as time goes by they've been coming more accurate but old Enif here is just flat invisible.

007:34:21 Duke: Rog.

007:34:49 Collins: And, Houston, Apollo 11. Understand that the same three gimbal angles you gave me should be valid for star 45 as well. Is that affirmative?

007:34:58 Duke: I believe that's right. Stand by one. Over.

007:35:00 Collins: Okay.

007:35:03 Duke: That is negative. Stand by one.

007:35:04 Collins: Okay. Because there's quite a difference between the gimbal angles you have and the gimbal angles the program wants, but with inaccurate state vector, I'm inclined not to believe the program.

007:35:16 Duke: Stand by.

007:35:31 Aldrin: Houston, Apollo 11. Aldrin is back on the line.

007:35:36 Duke: Roger. Copy.

007:35:40 Aldrin: Read you five-by.

007:35:42 Duke: Roger. Same, Buzz. And, 11, the angles for you are 1978 for roll, 1285 pitch, 3400 yaw.

007:35:58 Collins: Okay. Just as a matter of comparison, P23 for this star would like to go to 235.66, 154.31, and 31365. Over.

007:36:15 Duke: Roger. We copy, 11. We understand that the program can give you almost an infinite combination of angles in P23, and it's not too unreasonable. If you'll stand by, we'll look at these that we see on the DSKY. Over.

007:36:31 Collins: Okay. Then in the meantime I'll just go ahead and maneuver to yours. 197.8, 128.5, and 340.0.

007:36:38 Duke: Roger.

007:43:24 Collins: Houston, Apollo 11.

007:43:26 Duke: Go ahead. Over.

007:43:28 Collins: Okay, Charlie. If the attitude you gave me on star number 45... The reticle is off, I'd say, a good 30 degrees in roll, and the star is not in sight. Over.

007:43:44 Duke: Roger. Stand by.

007:43:47 Collins: I think something's wrong with those attitudes.

007:45:14 Duke: Hello, Apollo 11. Houston. I wondered if you have Auto optics selected. Over.

007:45:21 Collins: That's affirmative.

007:45:26 Duke: Roger. Looks like to us we need a Proceed, Mike, to get the sextant pointed at the star. Over.

[Mission Control can see that Mike has ommitted to press the Proceed button on the DSKY, which commands the on-board computer to implement the chosen program.]

007:46:30 Duke: 11, Houston. Those shaft and trunnion angles were exactly what we were computing on the ground. Over.

007:46:45 Collins: Okay. I'm going to trim up the attitude here and give it another try.

007:47:55 Collins: Okay. I have this star loud and clear now, Charlie, so I might as well do a bunch of marks on this one to get a good horizon count.

007:48:03 Duke: Roger. Stand by.

007:48:10 Collins: It still looks like I'm far from the substellar point. However, I'm off quite a bit in roll.

007:48:18 Duke: Roger. We'd like you to mark right where it is now, Mike, and we'd like two sets of marks on this. Over.

007:48:28 Collins: Okay. Fine. But the reticle is not parallel to the horizon. I have to move off quite a bit in order to get it parallel to the horizon.

007:48:40 Duke: Apollo 11, Houston. Our procedures guys are saying that the reticle does not have to be parallel. Over.

007:48:51 Collins: Well then we're not at the substellar point, if we're not.

007:48:54 Duke: Rog.

007:51:39 Collins: Houston, you copy that Noun 49?

007:51:41 Duke: Roger. We see it, 11. Stand by.

007:52:09 Duke: Apollo 11, Houston. We'd like you to accept this one and every mark thereafter. Over.

007:52:16 Collins: Okay.

007:52:55 Collins: You need me to wait in the Noun 49 display for any length of time?

007:53:01 Duke: Negative.

007:53:02 Collins: Okay.

007:54:29 Collins: Okay, Charlie. I'd be glad to give you as many of these as you like.

007:54:34 Duke: Roger. We'd like six marks on star 45, Mike, and then we'll probably go back to star 2 again. Stand by. We'll have further word on that.

007:54:43 Collins: Okay.

007:55:20 Collins: They seem to be getting smaller, Charlie? Are you sure you wouldn't like some more?

007:55:23 Duke: Stand by, Mike.

007:55:28 Collins: It's no trouble.

007:55:31 Duke: Rog. Stand by. Out.

007:56:07 Duke: Apollo 11, Houston. We'd like you to do two more on star 45. Over.

007:56:14 Collins: Okay.

007:58:02 Collins: Okay, Charlie. There's your two more marks. Where do you want to go from here?

007:58:06 Duke: Stand by.

007:58:21 Duke: Hello, Apollo 11, Houston. We'd like you to go back to star number 2 with an attitude as follows: roll, 195.2; pitch, 123.9; yaw, 340.0. Mike, that'll give you a trunnion angle of about 31.4. Over.

007:58:45 Collins: Okay. U,nderstand star number 2 and roll 195.2; pitch, 123.9; and yaw, 340.0. Over.

007:58:57 Duke: That's affirmative.

007:59:01 Collins: Okay.

008:02:07 Collins: Okay, Charlie. I'm there, and I've got a trunnion angle of 30.5 degrees. Again, misaligned considerably in roll and I do believe that's important to getting good marks.

008:02:20 Duke: Stand by.

008:02:40 Collins: See, if I'm - my reticle's not parallel, then I'm not marking normal to the horizon and I'm not marking at the substellar point. I'm marking off somewhere else.

008:02:50 Duke: Stand by one. Over.

008:02:52 Collins: Okay.

008:03:24 Duke: Apollo 11, Houston. The ground-computed values for your shaft and trunnion are just what you're getting on the DSKY there, Mike. The horizon looks cocked off to you - You look like you're off in roll because the angles that we gave you to maneuver to, to prevent LM reflection from fouling up your optics, we feel like a - You should go ahead and mark on the stars just as is. Over.

008:03:53 Collins: Okay.

008:04:08 Collins: I'll bet you a cup of coffee on it.

008:04:14 Duke: Ah, copy.

008:05:08 Collins: Verb - Noun 49 for you, Charlie.

008:05:13 Duke: Roger. Stand by.

008:05:45 Duke: Apollo 11, Houston. We'd like to accept this one and give us two more and that will be enough. Over.

008:05:52 Collins: Okay.

PAO: This is Apollo Control at 8 hours, 8 minutes. Apollo 11 now 38,812 nautical miles from Earth, and travelling at a speed of 9,682 feet per second. And we're just putting a call to the crew. We'll standby for...

008:08:25 Duke: Apollo 11, Houston. We see your termination on P23. Thank you very much. Mike, we'll have a - We're trying to work up a story here for you; we'll be with you momentarily on an explanation of what's happening. Over.

008:08:38 Collins: Okay, Charlie. It just appears to me that you have to have a reticle tangent to the horizon at the point at which you mark or else you're not at the substellar point; you're off laterally, and therefore you're measuring a larger trunnion angle than you should.

008:08:56 Duke: Seems so to me. Our procedures people are working on this, and we'll be back with you momentarily. Over.

008:09:03 Collins: Thanks, sir.

008:11:00 Duke: Hello, Apollo 11. Houston. We'd like you to go P00 and Accept. We'll have a PTC REFSMMAT for you momentarily. Over.

008:11:13 Collins: Roger. Going P00 and Accept.

PAO: The PTC REFSMMAT, which Capcom Charlie Duke just referred to, is the Passive Thermal Control attitude that the crew will place the spacecraft in. In this attitude the spacecraft will be rotated at a rate of about 3 revolutions per hour to maintain the proper temperature balance.

[The explanation of the PTC REFSMMAT given above by the PAO is simplified. A REFSMMAT is a definition of a particular orientation in space, measured with respect to the stars. The PTC REFSMMAT is one to which the spacecraft's guidance platform is aligned. It has been chosen so that when the spacecraft is orientated to rotate broadside on to the Sun, it will do so without the platform going into gimbal lock.]

008:14:02 Collins: You're Block. Thank you.

008:24:44 Duke: Hello, Apollo 11. Houston. We'd like you to do a P52, option 1 preferred, and establish PTC as listed in the Flight Plan at 12 hours. We'd like you to commence that right now, Mike. And we have some stars recommended for you. For stars 26, 30, and 24, when you get to attitude 000. Over.

008:25:19 Armstrong: Okay, Charlie. He's off the wick right now. Understand you're ready for us to do a P52, option 1?

008:25:31 Duke: 11, it's a P52, option 1 preferred. Over.

008:25:36 Armstrong: Roger. And, let's see, that is Spica, Menkent, and what else?

008:25:43 Duke: Roger. Stars - Codes are stars 26, 30, and 24. Over.

008:25:49 Armstrong: 24. Okay.

008:35:42 Duke: Hello, Apollo 11. Houston. We notice your Program Alarm, Mike, was due to using these stars in the P23 attitude. If you'll go to 000, the stars we gave you will work. Over.

008:36:02 Collins: Okay. Understand.

008:41:19 Duke: Hello, Apollo 11. Houston. Prior to you starting your P52, we'd like to give you a new CSM state vector. Over.

008:41:29 Collins: Roger. Wait till we finish the maneuver and we'll give you the DSKY.

008:41:37 Duke: Roger. We're standing by.

008:53:07 Collins: Houston, Apollo 11. The DSKY is yours.

008:53:12 Duke: Apollo 11, Houston. Go ahead. Over.

008:53:15 Collins: Roger. The DSKY is yours.

[The Apollo 11 crew have handed over control of their onboard computer to Houston.]

PAO: This is Apollo Control at 8 hours, 59 minutes into the flight of Apollo 11. The spacecraft altitude is currently reading 42,753 nautical miles, and we show a velocity of about 9,100 feet per second. We are in the process now of up-linking to the spacecraft the attitude for the Passive Thermal Control mode. Under this mode the spacecraft will be rotated about its X axis at a rate of about 3 revolutions per hour to maintain a proper temperature balance within the spacecraft. The crew has completed the midcourse navigation exercise. They will shortly be aligning the spacecraft stable platform, used as an attitude reference in the guidance system. This is a routine procedure, and following that, the spacecraft will be placed in the Passive Thermal Control mode where normally it would be left during the sleep period. The cabin temperature in the Command Module, has been running between 65 and 70 degrees. The current spacecraft weight is 96,460 pounds.

009:00:59 Duke: Hello, Apollo 11. Houston. You can do the Verb 66. The computer is yours, and then the P52, option 1 preferred. Over.

009:01:06 Collins: Roger.

PAO: This is Apollo Control at 9 hours, 13 minutes into the flight of Apollo 11. Based on biomedical data, a flight surgeon reports that it appears the crew removed their pressure garments - their pressure suits at about 8:00pm for the Commander Neil Armstrong and Command Module Pilot Mike Collins. Lunar Module Pilot Buzz Aldrin apparently got out of his pressure suit about 1 hour earlier or about 7 hours Ground Elapsed Time. The spacecraft is currently 44,529 nautical miles from Earth and the velocity has dropped now to 8,983 feet per second. We do have rather poor lock with the spacecraft antenna at this time accounting for the noise on the air-to-ground circuit. We'll take down the circuit until we re-establish better lock and we'll record any conversations that occur in the interim. At 9 hours, 14 minutes; this is Apollo Control, Houston.

009:16:10 Duke: Hello, Apollo 11. Houston. Do you read? Over.

009:18:11 Duke: Hello, Apollo 11. Houston. If you read, this attitude 000 is pretty bad for our Comm. In fact, we've lost all data with you, and unreadable on the voice. We recommend you do the P52, option 1 preferred...

009:18:25 Collins:... not a very good attitude at all for Comm, and as soon as we finish our alignment, we'll maneuver it to a different attitude. Over.

009:18:34 Duke: Roger, 11. We copy. Recommend you go to this P52, option 1 preferred, and then go to PTC attitude. Over. Then we'll get some Comm. When you get there to PTC attitude, it'll be pitch 90, yaw 0 on the high gain. Over.

009:21:17 Collins: Houston, Apollo 11. Over.

009:21:19 Duke: Roger, 11. You're about one-by. Go ahead.

009:21:38 Duke: Apollo 11, Houston. You're about one-by. Go ahead. Over.

009:22:40 Collins: Houston, Apollo 11. Over.

009:22:43 Duke: Roger, 11. Read you about four-by. How me? Over.

009:22:46 Collins: You're loud and clear, Charlie. We pitched down some to get a better comm attitude.

009:22:51 Duke: Roger. Did you copy our recommendation on proceeding with the P52, Mike? Over.

009:22:58 Collins: Negative. We didn't. I've got that in work. I'm starting on P52.

009:23:01 Duke: Roger.

PAO: This is Apollo Control at 9 hours, 36 minutes into the flight of Apollo 11. The mission continuing to go smoothly at this point. The communications noise that we were experiencing previously cleared up after the crew was able to get the spacecraft in a good attitude for antenna lock-on and we had one brief conversation which we taped. We're presently communicating with the crew at this time. We'll pick up the tape and then continue to follow live conversation.

009:35:56 Collins: Houston, Apollo 11.

009:35:59 Duke: Go ahead, 11. Over.

009:36:01 Collins: Roger. Copy our torquing angles. We're about to torque them.

009:36:05 Duke: Roger. Stand by.

009:36:08 Collins: Rog. The reason for the delay there, Charlie, is that - difficult to find two stars that are not occulted by the LM and also are not in the midst of a man-made star field up here, with dumps.

009:36:21 Duke: Roger. We copy.

009:36:38 Duke: Hello, Apollo 11. Houston. You can torque the Noun 93. Over.

009:36:44 Collins: Okay.

PAO: That brings us up to date with the taped conversation that we had. We'll continue to stand by for any live communications with the spacecraft. Most of that conversation with Mike Collins involved the platform alignment that the crew is involved in at the present time, aligning the stable platform used by the guidance system as an attitude reference. Apollo 11 is presently 46,688 nautical miles from Earth and the velocity is 8,750 feet per second.

009:40:34 Collins: Okay, Houston. That completes the P52. We verified the third star with Antares, and Auto optics are pointing at it pretty closely. How do our platform drift angles look so far, Charlie?

009:40:46 Duke: Stand by.

009:40:56 Duke: Hello, Apollo 11. Houston. We didn't have a chance to get a good check for you. We're going to run a drift check from this alignment until the next one, approximately 12 hours, and we'll have something for you later. Over.

009:41:07 Collins: Okay.

009:41:46 Duke: Hello, Apollo 11. Houston. We'd like you to establish your PTC. We recommend you select quads Alpha and Delta. Over.

009:42:14 Armstrong: Roger. Understand. Alpha and Delta quads (faintly) for PTC.

009:42:19 Duke: That's affirmative.

009:52:53 Duke: Hello, Apollo 11. Houston. Would you verify that the Attitude Set switch is in GDC? Over.

009:53:06 Armstrong: The Set switch. Stand by one, Charlie.

009:53:09 Duke: Roger.

009:53:11 Armstrong: It is now.

009:53:14 Duke: Roger. It was on IMU?

009:53:17 Armstrong: That's affirmative.

009:53:19 Duke: Rog. Thank you.

010:03:29 Aldrin: Hi, Houston, Apollo 11. How many miles out do you have us now?

010:03:34 Duke: We have you - Stand by, Buzz. Roughly about 50,000. Stand by.

010:03:41 Aldrin: It's a beautiful sight.

010:03:46 Collins: Charlie, on the PTC, we're just waiting our 20 minutes here for all thruster activity to damp out. You might let us know how that's coming.

010:03:54 Duke: Roger. Will do. We have you about 48,000 miles now?

010:03:58 Collins: Thank you.

010:05:33 Collins: Houston, Apollo 11. We still have our oxygen fan on for Tank 2. Is that what you want?

010:05:40 Duke: Stand by.

010:05:45 Aldrin: Hey, Charlie, I can see the snow on the - on the mountains out in California, and it looks like LA doesn't have much of a smog problem today.

010:05:57 Duke: Roger, Buzz. Copy. Looks like there's a good view out there then.

010:06:00 Duke: And, Apollo 11, Houston. We'd like you to keep the O₂ fan on. It will give you an ECS configuration prior to sleep. Over.

010:06:14 Aldrin: Okay. Thanks.

010:06:46 Aldrin: Charlie, with the monocular, I can discern a definite green cast to the San Fernando Valley.

010:06:56 Duke: Roger.

010:07:00 Duke: How's Baja California look, Buzz?

010:07:07 Aldrin: Well, it's got some clouds up and down it, and there's a pretty good circulation system a couple of hundred miles off the west coast of California.

010:07:21 Duke: Roger. 11, we'd like you to close the waste storage vent valve right now.

010:07:28 Collins: Okay.

010:07:49 Collins: Waste storage vent valves closed.

010:07:51 Duke: Copy.

010:08:51 Duke: Hello, Apollo 11. Houston. We'd like - The rates are looking pretty good right now on the PTC, but we'd like you to continue holding. Over.

010:09:01 Collins: Okay. Fine.

010:20:28 Duke: Hello, Apollo 11. Houston. Your rates look really great, now. You can start your PTC.

010:20:33 Collins: Okay. Thanks, Charlie.

010:21:51 Armstrong: Houston, you read 11?

010:21:53 Duke: Roger. Go ahead, 11. Over.

010:21:56 Armstrong: Roger. If you'd like to delay PTC after - for 10 minutes or so, we can shoot you some TV of a seven-eighths Earth. That's - We'll leave that up to you.

010:22:12 Duke: Roger. Stand by.

010:22:50 Duke: Hello, Apollo 11. Houston. We'll have our answer for you on the TV in about one minute. Over.

PAO: This is Apollo Control at 10 hours, 26 minutes into the flight of Apollo 11.

010:25:56 Duke: Apollo 11, Houston. We're ready at Goldstone for the TV. It'll be recorded at Goldstone and then replayed back over here, Neil. Any time you want to turn her on, we're ready. Over.

010:26:14 Armstrong: Okay. It'll take us about 5 minutes to get rigged.

010:26:16 Duke: Roger.

PAO: Capcom Charlie Duke advised the crew that we would be recording the television at Goldstone. We don't have an estimate at this time as to how long it will take to get a playback of that from Goldstone.

010:26:31 Duke: Apollo 11, Houston. Could you verify the reading on your O₂ flow indicator? Over.

010:26:45 Aldrin: We're showing 0.2. We just inadvertently touched the Rapid Repress button. That made a temporary glitch in the flow.

010:26:55 Duke: Roger. During that glitch there, did it go almost a peg high? Over.

010:27:05 Aldrin: I'd believe that.

010:27:14 Duke: Apollo 11, Houston. Could you tell us - tell us if the O₂ flow indicator was pegged high prior to closing the waste storage vent valve? Over.

010:27:26 Aldrin: No, it was not.

010:27:29 Duke: Roger. Thank you.

010:30:59 Duke: Hello, Apollo 11. Houston. A while ago we tracked into the scan limits and disabled the Auto drive on the High Gain. We'd like you to position the antenna at pitch 30, yaw 270, go to Reacq; that will give us narrow beamwidth. Over.

010:31:27 Armstrong: That yaw 270 and pitch 3 - What was the pitch?

010:31:32 Duke: Pitch 30, Neil.

010:31:35 Armstrong: Okay. (Pause.) I think we've got you. (Pause.)

010:31:44 Duke: Roger. We've got a good signal there. Thank you much.

010:32:24 Armstrong: Okay, Houston. We are sending a picture of Earth down right now, so you can let us know if they're receiving at Goldstone.

010:32:36 Duke: Roger, 11. Goldstone is receiving the TV. Stand by. We'll let you know on the quality. Over.

010:33:34 Duke: Hello, Apollo 11. Houston. Goldstone says that the TV looks great. Over.

010:33:44 Armstrong: Roger. We're zooming in on Earth now.

010:33:54 Duke: Hello, Apollo 11. Houston. Did you copy? Over.

010:34:00 Armstrong: Roger. We copied, Charlie.

010:34:04 Duke: Roger. Your transmissions the last couple of times have been about two-by. Over.

010:34:10 Aldrin: Okay. How do you read me now?

010:34:11 Duke: Rog. You're five-by now.

010:34:12 Aldrin: Okay. We're zooming the lens on in, until it will just about fill the monitor.

010:34:20 Duke: Roger.

010:34:35 Aldrin: Okay. It's in full zoom, now.

010:34:40 Duke: Copy, 11.

010:34:43 Aldrin: And how about the f-stop? Is 22 going to be adequate?

010:34:49 Duke: Stand by. We'll get with the Goldstone TV guy. We don't have anything here at Houston. Stand by.

010:34:55 Aldrin: It looks good on the monitor, as far as the f-stop goes. Therefore, we just assumed it's okay at Goldstone.

010:35:26 Duke: Hello, Apollo 11. Houston. Goldstone says it - TV looks really great, five-by; we don't - The AGC looks like it's working fine. The f:22 is good; we have no real white spots. They're real pleased with it. Over.

010:35:42 Aldrin: Okay. You just cut out, Charlie. We understand that it's looking great. We'll leave it the way it is and wait for you to come back on.

010:35:51 Duke: Roger. How do you read me now? Over.

010:35:54 Aldrin: Five-by.

010:35:55 Duke: Okay. My comments were - My comments were from Goldstone that they see no white spots as we saw in 10. Looks like the AGC's working real well. The f:22 looks good. Over.

[The white spots refer to flaws in the television transmission from Apollo 10 two months earlier.]

010:36:24 Duke: Roger.

010:37:05 Duke: Hello, Apollo 11. Houston. We'd like you to keep the TV on for about 10 minutes or so, so we can get come good comparison on the camera. You can do anything your heart desires on the TV: interior, exterior, pan in and out, anything you'd like. Over.

010:37:46 Duke: 11, Houston. Over.

010:38:05 Collins: Houston, Apollo 11. Over.

010:38:06 Duke: Roger. Go ahead. Over.

010:38:09 Collins: Charlie, I'm sorry; you keep cutting out. We heard up to you can do anything, and then after that we didn't hear anything, and we knew that wasn't right anyhow because we can't. But what do you want us to do?

010:38:21 Duke: Roger. We'll check this uplink on our voice. That transmission on the TV was - We'd like to get about 10 minutes worth of signal at Goldstone so we can look at the camera quality back here at Houston for about 10 minutes or so when they patch it back into us. What we were saying was that you can go interior or exterior on the camera. On the exterior shots, we'd like to look...

010:38:47 Collins: You cut out again.

010:38:48 Duke: Stand by.

010:38:55 Collins: Start over with: We were saying.

010:39:36 Aldrin: Okay, Houston. You suppose you could turn the Earth a little bit so we could get a little bit more than just water?

010:39:45 Duke: Roger, 11. I don't think we got much control over that. Looks like you'll have to settle for the water.

010:40:01 Duke: 11, Houston. We're going to change - thinking about changing our voice up-link to another site. If you'll stand by, we'll see if we can improve the quality. Over.

010:40:11 Collins: Okay, Charlie.

010:40:12 Armstrong: We'll stand by for your call.

010:40:48 Duke: Apollo 11, Houston. We'll try once more on this TV request. We'd like 10 minutes worth of TV. And we'd like a narrative, if you could give us one, on the exterior shots. You could al - we also suggest you might try the - an interior position. Over.

010:41:10 Armstrong: Roger. We're seeing the center of the Earth as viewed from the spacecraft in the eastern Pacific Ocean. We have not been able to visually pick up the Hawaiian Island chain, but we can clearly see the western coast of North America, the United States, the San Joaquin Valley, the High Sierras, Baja California, and Mexico down as far as Acapulco, and the Yucatan Peninsula; and you can see on through Central America to the northern coast of South America, Venezuela, and Colombia. I'm not sure you'll be able to see all that on your screens down there.

010:42:04 Duke: Roger, Neil. We just wanted a narrative such that we can - When we get the playback, we can sort of correlate what we're seeing. Thank you very much.

010:42:19 Collins: I haven't seen anything but the DSKY so far.

010:42:23 Duke: Looks like they're hogging the windows.

010:42:29 Armstrong: You're right.

010:46:58 Duke: Hello, Apollo 11. Houston. On your cryos, we'd like, at this time, for you to place all four cryo heaters to Auto and turn off all four cryo fans. Over.

010:47:15 Aldrin: Okay. All four cryo heaters are Auto. And all four cryo fans are off, all off.

010:47:25 Duke: Roger. That's going to be your sleep configuration.

010:47:29 Aldrin: Okay.

010:47:30 Duke: And, Buzz, we'll be terminating the battery charge in about a half hour.

010:47:35 Aldrin: Roger.

010:47:58 Duke: Hello, Apollo 11. Houston. You can terminate the TV at your convenience. We've got enough tape, and you can start PTC at your convenience. The rates look super for starting up. Over.

010:48:14 Collins: Roger, Charlie.

PAO: This is Apollo Control at 10 hours, 51 minutes. That TV transmission lasted about 15 minutes. Goldstone reported that we did get good quality on it. We estimate that it will be somewhere between an hour and a half or two hours before we have the television available here in Houston to play back. The lines will have to be called up between Goldstone and Mission Control Center, and the conversion equipment brought up online before we'll be able to play back the television from that transmission. At the beginning of the TV transmission, the spacecraft was approximately 50,980 nautical miles from Earth, and at the conclusion they were about 52,248 nautical miles from Earth.

010:57:32 Duke: Apollo 11, Houston. We have a Flight Plan update for you and some P37 block data, if you're ready to copy. Over.

010:57:41 Armstrong: Stand by.

010:58:19 Collins: Okay, Houston. PTC is started now; looks good to us, and we'll be ready to copy in a minute or two.

010:58:24 Duke: Roger. Copy, 11.

010:58:59 Aldrin: Houston, Apollo 11. Ready to copy the Flight Plan update and P37.

010:59:04 Duke: Roger. Stand by one, Buzz.

010:59:21 Duke: Apollo 11, Houston. Coming at you with the P37 block data. Over.

010:59:28 Aldrin: Okay.

010:59:29 Duke: Roger. 027:44, 5363, minus 165, 073:14; 037:44, 8016, minus 165, 072:46; GET_I 046:44, 6141, minus 165, 097:03; 055:44, 8209, minus 165, 096:42. Ready for your readback. Over.

011:01:01 Aldrin: Roger. 027:44, 5363, minus 165, 073:14, 037:44, 8016, minus 165, 072:46; 046:44, 6141, minus 165, 097:03, 055:44, 8209, minus 165, 096:42. Over.

[P37 is a Return-to-Earth program in the computer for use in an abort situation. Data read up from Mission Control is entered in a standard form:

This form, here shown from the Flight Plan, has 14 places to write P37 data. Each place has a position for four separate items: the time of ignition, the desired change in velocity or Delta-V, the desired longitude for splashdown and the time the spacecraft would be expected to reach Entry interface, an altitude of 400,000 feet or 121 km.]

011:02:34 Aldrin: Okay. We've completed the filter change, and we'll get started on the fuel cell purge, and stand by for the LM/CM Delta-P.

011:02:42 Duke: Roger, 11. Would you hold off on the fuel cell purge? EECOM's saying we might not have to do that. Over.

011:02:51 Aldrin: Okay.

011:03:05 Collins: Charlie, the LM/CM Delta-P is 0.5.

011:03:17 Duke: Copy. 0.5. Out.

011:03:50 Duke: Hello, Apollo 11. Houston. We just decided to delete the O₂ fuel cell purge. Over.

011:03:56 Armstrong: Roger. Delete the O₂ fuel cell purge.

011:06:21 Duke: Hello, Apollo 11. Houston. We've been noting some funnies on the O₂ flow indicator transducer. We've kind of got a suspicion that the transducer. We expected to see an O₂ flow pegged high with the waste stowage vent to Vent. It was not. We also noted some funny indications when you closed the waste stowage vent valve. We're going to continue to look at this through the night, and we'll be with you in the morning with an assessment of the problem. Also, we'd like to ask specifically, when you place the waste stowage vent valve to Vent, does the detent - correction - does the arrow line up with the detent? Over.

011:07:18 Collins: Stand by one, Charlie. We'll give you something on the detent.

011:07:21 Duke: Roger.

011:07:28 Collins: Right now it's at Closed, and I'm lined up with Closed. Before I was at Vent; and best I can recall, it was quite accurately lined up with Vent. Would you like me to go to Vent again momentarily and see where it lines up?

011:07:42 Duke: That's negative. That question's answered. Thank you much.

011:07:46 Collins: Okay.

PAO: This is Apollo Control. During that last transmission you heard CapCom Charlie Duke advise the crew that we are not seeing as high an O₂, or oxygen flow, as we would have expected at this point. This would indicate that the enrichment of the cabin atmosphere, which was 60 percent oxygen, 40 percent nitrogen at launch and which is normally enriched with pure oxygen during the course of the flight, is not enriching as rapidly as we would expect. This could be a transducer problem - one of the devices that measures the O₂ flow rate - or possibly a partial obstruction of one of the vents. The problem is not thought to be significant at this point, and we'll be monitoring the O₂ flow during the night.

011:09:52 Duke: Hello, Apollo 11. Houston. We have an S-band configuration for you. Over.

011:10:00 Aldrin: Roger. Go ahead.

011:10:02 Duke: Roger, Buzz. We'd like you to place the S-band antenna Omni A switch to the Bravo position. S-band antenna Omni switch to the Omni position, the High Gain track to Manual, and the High Gain angles will be yaw 270, pitch minus 50. Over.

011:10:27 Aldrin: Roger. Understand. Omni to Baker and Omni, Manual. And the angles are yaw 270, pitch minus 50, and was that narrow or wide? Over.

011:10:47 Duke: Stand by. Roger. We'd like it in Wide, and you can set that configuration up now. Over.

011:10:56 Aldrin: It's in work.

011:13:04 Duke: Hello, Apollo 11. Houston. You can terminate the battery Bravo charge, and we'd like a crew status report. We're about to tell you good night. Over.

011:13:14 Armstrong: Roger. Stand by.

011:18:08 Armstrong: Houston, Apollo 11. The battery charging is complete, and the crew status report is as follows: radiation; CDR, 11002; CMP, 10002; LMP, 09003; negative medication; fit as a fiddle, over.

011:18:33 Duke: Roger. Copy, 11. Thank you much. We'd like to ask one question. Have you tried the gas separator on the water? How is that working? Over.

011:18:45 Armstrong: Yes. Mike's got a couple of comments on that.

011:18:49 Collins: It's working good so far, Charlie. We've got one installed on the water gun and the other one installed on the spigot down in the LEB, and we - mention one problem with them is that they leak at the junction between the food bag and the water filter. However, with that exception, they seem to be working pretty good. We were getting some gas through initially, and I think that was just getting the system purged out to begin with; and the last tubeful we poured was almost free of bubbles. Over.

011:19:31 Duke: Roger. Sounds good. We'll check in on that problem with the SPAN guys and let you know in the morning. If you have to call us tonight, we'd like you to do it on Down Voice Backup. We're configuring the MSFN for that mode; and as far as we can see, you're cleared for some z's. Over.

011:19:53 Collins: Okay. Maybe we'll get around to lunch.

011:19:57 Duke: How about a peanut butter and jelly?

PAO: This is Apollo Control at 11 hours, 29 minutes into the flight of Apollo 11. We don't expect to hear a great deal more from the crew tonight. At about 11 hours, 20 minutes we said good-night to them from Mission Control and they're beginning their sleep period about 2 hours early. The additional time available for sleep was made available by deleting the midcourse correction, the first opportunity which occurred at 11 hours, 45 minutes. That midcourse correction has been moved to Midcourse Correction 2, to the opportunity at Midcourse Correction 2 of which would occur tomorrow. The last conversation we had with the crew, we received a status report and a report that they had taken no medication and were "fit as a fiddle". We also got a report from Mike Collins on the gas separation unit which is being flown on this flight. This consists of 2 stainless steel cylinders about 5 inches long and about an inch to an inch and half in diameter. The cylinders are attached to the water gun or to the water spigot on the food preparation panel and remove the gas from the water as it flows through the filter. The filter actually has two filters inside. One which attracts water and one which repels it, in the process removing the gas. Mike Collins reported that the filters seem to be working quite well; that the water was coming out almost free of bubbles. He did report that they had a minor problem with a leak at the junction between the food bag and the filter. Mission Control advised that we would give that some thought and try to come up with some solution to it when they wake up tomorrow. At this time, Apollo 11 is 55,522 nautical miles from Earth, traveling at a velocity of 7,920 feet per second. This is Apollo Control at 11 hours, 32 minutes.

PAO: This is Apollo Control at 11 hours, 47 minutes into the flight of Apollo 11. At this time we are receiving the television data from Goldstone. The data is coming in. It will be processed here and converted, and we estimate that it will be available for playback in about 20 to 30 minutes and we will have a firm time on that as soon as possible. At the present time, Apollo 11 is 56,704 nautical miles from Earth, and the velocity is 7,821 feet per second. We've had no further conversations with the crew since we passed along a good night to them at 11 hours, 20 minutes; getting them to bed about 2 hours ahead of the scheduled time on the Flight Plan, as a result of the deletion of Midcourse Correction 1. At 11 hours, 48 minutes; this is Apollo Control.

PAO: This is Apollo Control at 12 hours, 5 minutes. We expect to have the unscheduled television transmission, which came in to Goldstone, California, and was taped there and has been transmitted to Mission Control Center, ready and converted for replay in color at 8:45pm Central Daylight Time. That would be about 7 minutes from now. The TV transmission runs for a total time of about 16 and a half minutes and is of an exterior shot out the window of the Earth. At the time of the transmission, Apollo 11 was some 50,980 nautical miles from Earth. The transmission came into Goldstone at Ground Elapsed Time of 10:32:40, and ended about 16 minutes, 16 and a half minutes later, when the spacecraft was at an altitude of 52,248 nautical miles. We'll stand by for a replay of that transmission at 8:45pm Central Daylight Time.

012:xx:xx SC: (Garbled.)

012:xx:xx Duke: Hello Apollo 11, Houston.

PAO: This is Apollo Control at 12 hours, 12 minutes. We expect to be ready to release the television transmission from the spacecraft which was received at Goldstone, California. That should be ready to go in a little less than a minute.

PAO: And we are starting to get lock-on from the tape replay and we expect that we will have a color picture shortly.

PAO: This is Apollo Control. The view that we have of the Earth disk at this time, as near as we can tell, the North Pole is to the left of the screen, the land mass that was visible was the western coast of the United States. The Earth then would appear to be rotated ninety degrees with the North Pole to the left and South America - the South American continent extending toward the upper right of the globe but not visible.

PAO: That concludes the unscheduled television transmission. That transmission came in about 2 hours ago at a Ground Elapsed Time of 10:32:40 beginning, lasted about 16 and a half minutes. At the beginning of the transmission Apollo 11 was about 50,980 nautical miles from Earth, and at the conclusion about 52,248 nautical miles. At the present time, the crew is in a scheduled rest period. They did indicate before going into the rest period, when we last heard from them, that they would probably use part of the time to get a bite to eat and then get some sleep. At this time, Apollo 11 is 59,908 nautical miles from Earth, traveling at a speed of 7,569 feet per second. At 12 hours, 31 minutes; this is Mission Control, Houston.

012:36:34 Duke: Hello, Apollo 11. Houston. I hope you aren't, - we aren't disturbing you. We'd like to terminate the Noun 65 now. Over.

012:36:41 Collins: Roger.

012:46:00 Duke: Apollo 11, Houston. Over.

012:46:05 Aldrin: Houston, Apollo 11...

012:46:08 Duke: Roger, Buzz. When you stopped - or, correction - when you terminated the Noun 65, it appears to us, you get a Verb 46 which collapsed the deadband back to 0.5. We're okay as long as you do not turn on any Auto RCS Select switches. Over.

012:46:30 Aldrin: Okay. I thought that was a - better way to clear the DSKY but evidently it isn't. Roger.

012:46:36 Duke: Roger. Verb 34 would have been a better procedure.

012:46:41 Aldrin: Yes. Thank you.

PAO: This is Apollo Control at 12 hours, 47 minutes. We've just put in a call to the crew. Flight Director Gene Kranz verified with the Surgeon that they had not gone to sleep at this point, and Capsule Communicator Charlie Duke has put in a call. We'll pick up the tape of the conversation and then stand by for any following live communication with the crew.

PAO: This is Apollo Control. We don't anticipate a great deal of further conversation with the crew. We expect they will attempt to get some sleep shortly. The conversation that just ended; we advised that through one of the computer programs, the deadband, or that area of excursions which the guidance system will allow before firing the RCS thrusters to correct it, had been narrowed from 30 degrees to ½ a degree. What this would mean, if the RCS jets were enabled, is that unless the crew reselected the 30-degree deadband, the jets would be firing more frequently to keep the spacecraft within the narrower limits. Since the spacecraft is very stable at this point, very few waddling motions, it was felt that the narrower deadband was acceptable, the jets are not enabled and the crew would not be disturbed by firing of the Reaction Control System jets even if the spacecraft moved out of the ½-degree deadband. In the event of any large excursions, which we would not expect, based on a Passive Thermal Control mode used in Apollo 10, it would be possible to awaken the crew from the ground and have the situation corrected. We would not expect, however, for the spacecraft attitude to change significantly during the night, and we do intend to continue in the Passive Thermal Control mode as it is presently set up. At this time, Apollo 11 is 61,509 nautical miles from Earth, traveling at a speed of 7,449 feet per second which would translate to about 5,000 miles an hour. At 12 hours, 54 minutes; this is Apollo Control, Houston.

PAO: This is Apollo Control at 13 hours, 27 minutes into the flight of Apollo 11. The spacecraft now travelling at a speed of 7,279 feet per second which would be about 4,963 miles an hour, and it's at a distance of 63,880 nautical miles from Earth. Our Flight Surgeon reported a short while ago that Command Modue Pilot Mike Collins appeared to be sleeping soundly at this time. Biomedical data on the other two crewmen indicates that they are still awake. We've had no further conversation with the spacecraft since our last report, and it appears that the crew will be getting some good rest either as scheduled or perhaps a little earlier than scheduled in the Flight Plan. At 13 hours, 28 minutes; this is Mission Control, Houston.

PAO: This is Apollo Control at 14 hours, 6 minutes into the flight of Apollo 11. The mission is progressing very smoothly. All spacecraft systems are functioning normally at this time, and the Flight Surgeon reports that all three crewmen appear to be sleeping. For Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin, they appeared to begin sleeping about 5 minutes ago. Command module Pilot Mike Collins has been asleep for about an additional 30 minuts to an hour. At the present time, Apollo 11 is 66,554 nautical miles from Earth and travelling at a speed of about seventy thousand - or rather 7,095 feet per second, which would be about 4,800 miles an hour. We've had no further conversation with the crew since our last report and, as I said, the - all three crewmen appear to be sleeping at this time. At 14 hours, 7 minutes; this is Apollo Control, Houston.

PAO: This is Apollo Control; 14 hours, 25 minutes into the flight of Apollo 11. The spacecraft presently 67,819 nautical miles from Earth, traveling at a speed of 7,012 feet per second. Here in Mission Control, the shift change is in progress. Flight Director Glynn Lunney and his team of flight controllers coming on to replace Gene Kranz and his White Team. The Capsule Communicator on the upcoming shift will be Ron Evans, and we anticipate that the change-of-shift briefing for this shift will begin in about 10 or 15 minutes. At 14 hours, 26 minutes; this is Apollo Control, Houston.

[This marks the end of Flight Day 1 on Apollo 11. While the crew sleep, the Public Affairs Officer continues with occasional commentary through the night, in the next chapter.]
