CC: Apollo 11, this is Houston. We request you use OMNI Charlie at this time. Over.
UNKNOWN: Okay. Going to OMNI C_arlie.
LMP: Roger. Seems to me since we know orbits so precisely, and know where the stars are so pre- cisely, and the time of setting of a star or a planet to so very fine a degree, that this might be a pretty good means of measuring the altitude of the horizon ...
CMP: Hey, Houston. I'm looking north up toward Aristarchu$ now, and I can't really tell at that dist.ance whether I am really looking at Aristarchus, but there's an area that is considerably more iltuininated than the surrounding area. It just has - seems to have a slight amount of fluorescence to it. A crater can be seen, and the _rea around the crater is quite bright.
CC: Roger, 11. We copy.
LMP: Houston, Apollo 11. Looking up at the same area and now it does seem to be reflecting some of the earthshine. I'm not sure whether it was worked out to be about zero phase to - Well, at least there is one wall of the crater that seems to be more illuminated than the others, and that one - if we are lining up with the Earth cor- rectly, does seem to put it about at zero phase. That area is definitely lighter than anything else that I could see out this window. I am not sure that I am really identifying any phos- phorescence, but that definitely is lighter than anything else in the neighborhood.
CC: 11, this is Houston. Can you discern any differ- ence in color of the illumination, and is that an inner or an outer wall from the crater? Over.
UNKNOWN: Roger. That's an inner wall of the crater.
UNKNOWN: No, there doesn't appear to be any color involved in it, Bruce.
CC: Roger. You said inner wall. Would that be the inner edge of the northern surface?
UNKNOWN: I guess it would be _he inner edge of the west- northwest part, the part that would be more nearly normal if you were looking at it from the Earth.
CC: 11, Houston. Have you used the monocl._lar on this? Over.
LMP: Roger. Like you to know this quest for science has caused me to lose my E-memory program, it's in here somewhere, but I can't find it.
CC: 11, this is Houston. We're - we're he_ring only a partial COMM. Say again please.
CDR: I think ...
CDR: Houston, we will give it a try if we have the opportunity on next - when we are not in the middle of lunch, and trying to find the monocular.
CC: Roger. Copied you that time. Expect in the next REV you will probably be getting ready for LOI-2.
CC: So, let's wind this up, and since we've got some other things to talk to you about in a few minutes. Over.
CC: Apollo 11, this is Over.
CC: 11, this is Houston. We're targeting - planning to make the LOI-2 burn now using bank A only. We'11 have the P;_D and everything for you next time around. Just trying to economi _e a little on bank B. Bank B is holding, thoug,_.
CC: 11, Houston. In order to improve the communi- cations a little bit here, we'd like to try to get you on the high-gain antenna. We're recom- mending a Ditch angle of O, yaw 355 - I say again 355, the track switch to MANUAL, and wide beam- wi dth. Over.
CDR: Okay. You ready to switch to high gain now?
CC: 11, Houston. Do you read?
CDR: Roger. We read you. It seems to be rather mar- ginal on the high gain.
UNKNOWN: ° Houston, Apollo 1t. Could you give us a time of crossing the prime meridian 150 west? Over.
CC: Roger. Stand by about a half a second, here. Okay. Your time of crossing the 150 west merid- ian will be 77 50 05. Over.
CC: 11, this is Houston. We have about 6 minutes remaining until LOS, and in order that we may configure our ground lines, we'd like to know if you're still planning to have the TV up with the beginning of the next pass. Over.
UNKNOWN: Roger, Houston. We'11 try to have it ready.
CC: This is Houston. We are inquiring if it is your plan to. Over.
CDR: It never was our plan to; but it's in the flight plan, so I guess we'11 do it.
CC: For use in connection with the prime m<_ridian crossing, you have an orbital period now of 2 hours 8 minutes and 37 seconds. Over.
CC: Apollo 11, this is Houston. A little over 2 min- utes to LOS. All your systems parameters and orbit are looking good from the ground. We have AOS on the other side at 78 23 31. Over.
CDR: Roger. 78 23 21.
CC: Roger. That was 31 on the end.
LMP: This is Apollo 11. Are you picking up our sig- nals okay?
CC: Apollo 11, this is Houston. Affirmative. We are reading you loud and clear on voice and we have a good clear TV picture, a little bright crater in the - -
LMP: - - No, no, no - -
CC: - - the bottom of the picture. I guess that's the spot on the tube.
UNKNOWN: I'm sorry about that one.
CC: And if you give us POO and ACCEPT, we will uplink our new state vector and target load to you.
LMP: Houston, Apollo 11. One of the larger craters on the back side - I noticed a small, dark speck on the outer wall and I put the monocular on it. I was able to see - oh, an area maybe a quarter of a mile in diameter. It was really a fresh- looking dark-colored pit, and that seems to be in contrast with all the other fresh little craters or holes that you can perceive on the walls of any of these craters. Around this particular one there seems to be two or three of these - es- pecially the one that caught my attention. Quite remarkable. Over.
CC: Roger. Do you have a location on that one?
LMP: No, not a precise one. I've got several pictures of it, though.
CC: We're getting a beautiful picture in down there now, 11. The color's coming in quite clearly, and we can see the horizon and the relative blackness of space, and without getting into the question of grays and browns, it looks, at least on our monitor, sort of a brownish-gray.
LMP: That's a good, reasonable way of describing it. It appears to me as though it made a difference Just sitting back in the tunnel and gazing at all windows; it makes a difference which one you're looking out of. For example, the camera right now is looking out the number 5 window, and it definitely gives a rosier or tanner tinge, and especially when you look straight through it not at an angle. Over.
UNKNOWN: And if you rear back 95 or 100 degrees ...
MS: ... Still holding ... Okay.
CC: Say again, 117
LMP: I'd say we're about 95 degrees east, coming up on Smyth's Sea.
CC: Roger. And for your information, we show you at an altitude of about 92 miles above the surface right now.
CMP: Houston, Apollo 11. Could you observe a differ- ence in the N2 pressures before LOI? It seems to me as though the Cwo were not equal on the ... B tank was a little ]ow on pressure. Over.
CMP: I'm flying it in SPS minimum impulse, Houston, and it's rather difficult to keep it on a constant data. The LM wants to wander up and down. I'm not sure if it's in response to MASCONN's or what, but I can get it completely stabilized in DATA and let it alone, and in another couple of minutes it will have developed its own rate.
CC: This is Houston. Roger.
CMP: Houston, we'11 be moving shortly from the side window to the hatch window, and we'11 try and pick up some of the landmarks that we'11 be looking at as we approach the powered descent. Over.
CC: 11, this is Houston. Roger. And we're through with the uplinks; the computer is yours. You can go to BLOCK and we'11 have the information on nitrogen for you shortly. Over.
LMP: Okay, Houston. Several minutes ago I was exactly steady on data, and since then I have been moving toward the LM, pointed straight down toward the radius vector, and that's been despite a number of down minimum-pitch impulses.
LMP: We're over Smyth's Sea right now.
CC: Roger. i i 51/1
CMP: We're about 88 degrees east, I would estimate.
CC: We show you about south of the - southwest of the crater Jansky right now.
CC: Smyth Sea doesn't look much like a sea. It - The area which is devoid of craters, of which there's not very much, is sort of a hilly looking area. It's not like the maria at all.
CC: Roge r . We copy that about the sea, and it looks like you were Just giving us a view of the crater Neper, the large crater on the left, and Jansky on the right.
CMP: We think you're close, but no cigar.
CC: 11, this is Houston. Would you care tc_ comment on some of these craters as we go by?
CDR: Roger. We're approaching the approach path to ignition. This is equivalent to 13 mil_utes before ignition, and we're at about 83 degrees, I guess - 83 degrees east. That correspond to location Yo_'re holding there presently?
CC: Roger. We're showing your present position as about 7T - 76 degreem east looking back towards the east.
CMP: Hey, you should be looking back at Smyth Sea now.
CDR: Okay. /
CMP: Houston, what you're seeing in the middle of th_ screen now is the crater Schubert and Gilbert U is in the center right now; and this comes up at about -a little over 12.:minutes before power decent_;' Instead of me looking - Instead of looking back at it, we'd be looking straight down at it in descent.
CC: And we show you at an altitude now of about ll0 miles; and, of course, you'11 be considerably lower at the initiation of powered descent. ',F? , }_ /'
CMP: Okay, Houston. Look at register 3 on the DSKY data.. This data is increasing toward my desired of 315; and I'11 let the hand controller alone here, and I'11 bet you it reverses itself.
CC: Roger, 11. We're watching the DSKY now, and it's still coming in beautifully on the TV.
UNKNOWN: Okay. There's - on the right side of the screen at the present time, there's a triple crater with - with a small crater between the first and second; and the one at the bottom of the screen is Schubert Y. Zoom in; it does have a central peak in Schubert Y. Actually, several of them, and you can observe those plus the rim craters at the bottom of your screen.
C: Roger. We're seeing the central pea_ quite clearly now.
UNKNOWN: Okay. We're zooming in now on a crater called Schubert N. Schubert N, very conical inside walls and the bottom appears to be nearly flat.
CMP: Look at data on the DSKY. It's stabilized and is holding steady now.
LMP: Looking out the window I can see a number of small craters on the bottom of Schubert N.
CMP: We're coming up on the Foaming Sea where I'11 be doing some P22 marking on a crater oi my choice, name of crater, Camp.
CC: Okay. WeTll be watching for Neper.
UNKNOWN: And notice register 3 has reversed itself, and it's heading back the other way now without any pitch thruster firing.
CC: Roger, Mike. We confirm that you've changed the direction of your pitch rate.
CMP: Generally speaking - -
LMP: The crater - -
CMP: - - The tendency seems to be to pull the LM down toward the center of the Moon there as in a gravity gradient experiment.
CC: Roger, 11. We copy - -
CMP: It may have something to do with MASSCON's or it may - -
CC: Roger. We copy ...
CMP: It may have something to do with MASSCON's or it may just be the peculiarity of the DSKY display.
CC: Okay. We've observed the behavior of your DSKY, and I think we've got the data here to work on it. Let us grind around a little while on it, and we'11 report back to you, probably in a REV or two.
CMP: Okay. Well, in the meantime, I'm going to pitch down toward 315.
CC: Three craters - three horizontal craters that you now have in the field of view are immediately underneath the ground track. The right-hand is the largest crater that you see, Dubiago P.
CC: Roger. We concur on the identification of that crater.
CC: And we show you coming up on landmark Alfa 1 here shortly.
UNKNOWN: Roger. M_ke's having his first look a_ Alfa 1 at the present time.
CMP: Yea. It's a very bright crater. It's not a large one but an extremely bright one. It looks like a very recent and, I would guess, impact crater with rays streaming out in all directions which should make my -Correction - the Foaming Sea easy to see coming up on it now. Crater Camp is one of the smaller ones out on the - on the floor of the Fo_ming Sea.
CC: Here we show you over the Sea of Fertility now, and we ought to have Langrenus down south of track a few degrees, about 9 degrees south of track.
LMP: Now the crater that's in the center of the screen now is Webb. We'd be looking straight down on it at about 6 minutes before power descent. It has a relatively flat bottom to the crater, and you can see maybe two or three craters that are in tile bottom of it on the western wall, the wall that's now nearest the - the camera. Near the bottom of the screen, we on can see a dimple crater, Just the outside. And then coming back toward the bottom of the screen and to the left, you can see a series of depressions. It's this type of connected craters that give us most interest to discover why they're in the particular pattern that they're in. I'11 zoom the camera in now and try and give you a closer look at it.
CC: Roger. We're observing the dimple crater now. The central peak we can see on the Orbiter photos doesn't seem to stand out very well here.
LMP: Well, they're not central peaks. They're depres- sions in the center.
CC: Roger. And
UNKNOWN: you'11 notice on the pitch thruster activity, I've still - I've put in a dozen mininum impulses in pttchdown, and I'm still far from correcting back to 315.
LMP: We're moving the camera over to the r_ght window now _o give you Langrenus, its - its several central peaks and -
CC: Roger. We got Langrenus in our screen now.
CC: Okay, 11. This is Houston. We're getting a beautiful picture of Langrenus now with its r_ther conspicuous central peak.
CMP: The Sea of Fertility doesn't look very fertile to me. I don't know who named it.
CDR: Well, it may have been named by a gentleman whom this crater was named after, Langrenus. Langrenus was a cartographer to the King of Spain and made one of the - one of the early reasonably accurate maps of the Moon.
CC: Roger. That's very interesting - -
CDR: ... at least it sounds better for our purposes than the Sea of Crises.
CC: Amen to that.
CC: Okay. It looks like you're coming inside now on the camera.
LMP: Well, I can't get behind to see the monitor. I'11 bring the focus in, but we're going to be looking down past one of the LM quads and one of the antennas almost straight down at the ground track that we'11 be seeing coming in now. I guess there's maybe 2 or 3 minutes before power descent.
UNKNOWN: All right, that should put the _I structure about in focus, and I'm going to move it out to infin- ity and then expand the field of view.
LMP: Crater Secchi is out my window now, window num- ber 2.
CC: Hello, Apollo 11. This is Houston. We show you coming up on the terminator at 78 53, about 7 min- utes from now, and we've also got the LOI-2 and TEI-5 PAD's ready for you after the TV whenever you want to terminate. Over.
CC: And we're getting a good view of the track lead- ing into the landing site now and -
CC: Okay, And it looks like we got Secchi K, went by about 10 seconds ago; coming up on Apollo Ridge. ,
CC: And in the right-hand portion of our screen right now, we can see Messier Alfa and Bravo with the light-colored rays streaming off in o:_e direction.
UNKNOWN: I don't know if you can make out, but in the Sea of Fertility there are a number of craters that are Just barely discernible, old, old cra- ters whose outlines are just barely able to be seen.
CC: Roger. I think we can make them out. The color really enhances our ability to discern features and craters over what we see in real time on our black and white monitor.
LMP: Right. The - At these low Sun angles, there's no trace of brown, it's now returned to a very gray appearance and, like the 8 crew says, it has a look of plaster of paris to it at this Sun angle, which is completely lacking in ...
UNKNOWN: This is very close to ignition point for power descent. Just passing Mount Marilyn that - that triangular-shaped mountain that you see in the center of the screen at the present time with crater Secchi Theta on top of the far northern edge of the mountain.
CC: Roger. We're getting a good view of Mount Marilyn and the Secchi Theta.
LMP: And now we're looking at what we call Boot Hill; occurs 20 seconds into the descent.
LMP: The bright, sharp-rimmed crater at the very right edge of the screen, Censorinus T. Now passing the - the 1-minute point in power descent.
CC: Roger. And for your information, your current altitude is 148 nautical miles above the surface.
LMP: Don't you think? aL1
CMP: I'm unable to determine altitude at looking out the window. I couldn't tell whetler we were down at 60 or up at 170.
CC: I bet you could tell if you were down at 50 000 feet.
CMP: I wouldn't be surprised.
UNKNOWN: We're passing some steep ridges here. The edge of some old craters that were photographed by Apollo 10; and those - the crew of Apollo 10 was very impressed with the steepness of these ridges when they came over them at about 50 000 feet.
CC: Roger. We can observe they're also steep even from this altitude. You got quite a shadow being cast by the Sun at these low angles.
LMP: The entire surface is getting considerably darker than the surface that we looked at previously when the Sun was quite high above us. The crater in the - bright crater in the center cf the screen, - well, the smaller one is Censorinus.
CC: Roger. And we show you iow over 1 minute from the terminator at the present time.
LMP: How's the brightness of the picture you're receiving? You think we ought to open f-stop some as we approach the terminator?
CC: Yes. The brightness is still doing q_ite well. You can go ahead and open it up a sto_ or two. The a_tomatic light level compensation seems to be working beautifully.
UNKNOWN: There's a good picture of Boot Hill.
CC: Roger. We're--
LMP: Three minutes and 15 seconds into the descent.
CC: Roger. We're seeing Boot Hill now.
UNKNOWN: ,° The next crater coming into the bottom, that's Duke Island right there, and to the left, the crater - the largest of the craters n_ar the center of the picture right now is Ma_kelyne W. This is a position check during desce_% at about 3 minutes and 39 seconds, and it's otu down- range position check and cross-range r osition check prior to yawing over face up to acquire the landing radar. Past this point, we would be unable to see the surface below us until getting very near the landing area.
CC: Roger. I imagine you'11 get a - you'11 get a real good look at that tomorrow afternoon. LMm{'
UNKNOWN: Rille is the one that was referred to in Apollo 10 as Sidewinder.
CMP: That's a good name, too: Sidewinder and Diamondback. It looks like a couple of snakes down there in a lake bed.
LMP: And we're approaching the terminator now. See the - -
LMP: Contrast has increased and only the sunlit side of these ridges remain illuminated, while the dark sides and the shadow will become com- pletely black.
CC: 11, this is Houston. The picture's getting a little grainy now. You might go ahead and open up the f-stop.
LMP: Landing point is just barely in the darkness. That one crater, the upper part of which you see, lower part completely in darkness. The small, well-defined crater is Moltke, which is about abeam of the landing sight.
CC: Roger. We can just see; it looks like a little less than half of its rim right now.
CC: And we can make out just barely some features on the surface, maybe from earthshine.
CC: Are you wide open on the f-stop at this time?
CMP: Yes, we are.
LMP: Yes. And it looks like we're Just abcut to get the Sun coming into the lens, so we'11 have to move the camera away.
CMP: We can't see any earthshine or any surface features at all in earthshine now due to the fact that the I_M is very bright and is causing our pupils to contract. It's a very fantastic view to see the terminator as you look along the edge of it. I think you'11 agree that some of these craters that you're seeing in the picture now are really accentuated by the lengthening of the shadows as they come close to the terminator.
CC: Yes. It's a very beautiful and a rugged sight that we've got on the screen now.
CMP: And I think you've got some interesting data on thruster firing versus pitch angle. It looks like that LM Just wants to head down towards the surface, is all.
CC: Roger. T have a comment here that says that's what the LM was built for.
CMP: I believe!
UNKNOWN: And as the Moon sinks slowly in the west, Apollo 11 bids good day to you.
CC: Roger. We sort of thought it was the Sun setting in the east.
CMP: Well, it depends on your point of view.
CC: Apollo 11, Houston. When you're ream) to copy, I have an LOI-2 PAD and a TEI-5 PAD. Over.
UNKNOWN: I'm passing 182 inertial. I'm going _nertial n ow.
UNKNOWN: Ready to copy LOI-2 PAD.
CC: Roger on the inertial. And here we go on the LOI-2 PAD. LOI-2, SPS/G&N: 38320, plus 166, minus 081; TIG 080 11 3603. NOUN 81: minus 01408, minus all balls, minus 0C743.

Remarks: On your DAP load, we would like am R1 20101 vice the value which appears in the flight plan. In making the sextant star che¢.k this must be done between GET of 79 30 10, at which time the star comes above the horizon, and 79 52 10, which is your local sunrise due to the fact that this star's relatively close to the Sun. Your burn orienta- tion is heads down, retrograde pitched up 28 degress with respect to local horizontal. The calculated values for NOUN 42 are HA 65.6 and _ 54.6. Both of those being plus. Read back. Over. 51/10 SPS/G&N:

CC: Apollo 11, this is Houston.
CMP: Houston, you want us back on downvoice backup? Over.
CC: Apollo 11, this is Houston. That's alfirmative on the downvoice backup. We'd like ycu to con- firm your UPTELEMETRY switch in the NORMAL posi- tion. Over.
CMP: Roger. It's in BLOCK. Did you get us the - You got us a new CSM state vector and an LOI-2 target load in between all that television, didn't you?
CC: And what I'm asking for is the switchover to - -
CMP: The UPTELEMETRY switch is in NORMAL. Over.
CC: Roger. During the LOI-1 burn, your ermine burned a little bit more propellant than we predicted, and consequently, we'd like to update - or send you a new TEI-4 PAD. Over.
CMP: Our chamber pressure onboard was higher that time, too. It's all on the onboard tape, the time entry, and the chamber pressure_ but to make a lo_ story short, it worked it_ way up to 100.
CC: And down here, we showed a chamber pressure of on the order of 103 to 104 psi during your burn on playback.
LMP: Go ahead with the TEI-4.
CC: Roger. TEI-4 revised: SPS/G&N: 38320, minus 055, plus 060 084 30 2749, plus 31380, plus 03475, minus 01032; roll NA, pitch 034. Rest of the PAD is NA. Ullage two Jets 16 sec- onds, undocked. No LOI-2. Over.

CC: Roger. We've been looking at your systems data on playback, and everything is looking good. In particular, the EPS looks good. I would like to remind you, though, of a request to perform this burn on the bank A ball valves only, and you are GO for LOI-2. Also, we have currently in the flight plan, you scheduled tomorrow to start entering the LM at about 96 hours GET, and we'd like to know if you have any plans to initiate this ingress into the LM earlier. If so, we can call the people in ahead of time. Over.
CC: Well, we didn't have any plans to. N,_. We just wanted to be ready at that time.
CC: Roger. We Just wanted to make sure that we were ready when you were ready. Over.
LMP: Okay. And to get the sextant star in LOI-2, that's roll zero. Is that affirmative?
CC: That's affirmative. Roll zero.
CC: APollo 11, Houston. Five minutes until LOS. And with respect to your request for the nitro- gen bottle pressures preburn, Just before the burn, we were showing 2270 pounds per square inch on bottle Alfa and 2350 on bottle Bravo. Over.
CMP: Apollo 11. Roger. Thank you.
CC: Apollo 11, this is Houston. Two minutes to LOS. Your AOS on the other side is 80 BB 21, and the friendly White Team will see you when you come out from behind the Moon.
CMP: Apollo i1. Roger.
CMP: Thank you, Bruce.
CC: Make that your friendly "Greens." Your friendly White Team CAP COMM will see you when you come out from behind the Moon. I think it's basically the Maroon Team here, and we "Greenies" are leaving.
CMP: Okay. I don't blame you, Hank.
CC: Roger. I'd rather be up there. 52/1
CC: Hello, Apollo 11. Houston. We're standing by. Over.
CDR: V minus 0.0, V minus 0.1, DELTA-V C minus 5.2, gy gz fuel 362, OX 364, unbalance plus 50, and our postburn now 94's, 66.1 by 54.4. Go ahead.
CC: Roger. We copy, Neil. Would you say again the DELTA-V ? We missed that. Over. z
CDR: Roger. That was minus 0.1.
CC: Roger. Copy the burn report. Sounds good.
CDR: And all looked good up here.
CC: Apollo 11, Houston. We missed your DEl_A-TIG and also your DELTA burn time. Over.
CDR: DELTA-TIG was zero and the burn time was 17 seconds.
CC: Copy 17.
CC: Apollo 11, Houston. We'11 be satisfied if you pump up the cabin to 5.4. Over.
CDR: Okay. We're showing about 5.2 right now.
CDR: And, Charlie, the LM/CM DELTA-P is just over 1 pound right now.
CC: Apollo 11, Houston. If you read, please attempt to acquire on the high gain. We're having trouble locking up on the TM and we have no voice. Over.
CC: Hello, Apollo 11, Apollo 11.
CC: Roger. We're reading you five-by. Go ahead. Over.
CDR: Roger. We have you on high gain now.
CC: Roger. We lost the TM and the voice for about 5 minutes here. We attempted a handover and fouled it up in some manner, but we got you back now. Thank you much.
CDR: Okay. We're pressurizing the LM at this time.
CC: Hello, Apollo 11. Houston. We have a P22 AUTO optics update for y_l if you're ready to copy. Over.
CC: Roger, Mike. It's landmark Alfa l: T1, 82 37 35; T2, 82 42 50. We're 7 miles north. Over.
CMP: Copy. P22: T1, time 82 37 35; T2, 82 42 50. And the target is 7 miles north. Thank you.
UNKNOWN: I get the distinct impression, Charlie, that mare there laps up over the edge of the mountains at the shorelines.
CC: Houston. On your comment about the mare lapping up tO the terrain - mountainous terrain, is that an impressioR like a lava flow coming in around ayrominence, Nell, or is it more -lcoks like it's sloping up at that point? Over.
CDR: It i_n't ' true everywhere, but there's certainly places where there seems to be a slope downward towards the shoreline on the m_re. In other words, from the mare down to the shoreline is a downward slope indicating that it might be a lava flow.
CDR: Crossing Duke Island and Maskelyne W.
CC: S_y again, Neil. Over.
CDR: We Just crossed Duke Island and Maskelyne W.
CC: Hello, Apollo 11. Houston. We're wondering if you've started into the LM yet. Over.
CDR: We have the CSM hatch out, the drogue and probe removed and stowed, and we're just abeut ready to open the LM hatch now.
CC: Roger. Th_zk you much, Nell. We'11 be standing by.
CDR: Okay, Charlie. We're in the LM. The docking index mark is the same.
LMP: Charlie, apparently there just doesn'l seem to be any slow way to get that REPRESS tc AUTO without making a big bang.
CC: Apollo 11, Houston. Say again. Over.
LMP: Roger. There just doesn't seem to be any slow way to get the REPRESS closed to AUTO and avoid a big bang. Over.
CC: We copy, Buzz. Thank you much. Out.
CC: We concur with that, Buzz.
CC: Apollo 11, Houston. We'11 have LOS 81 45, next AOS - Stand by.
CC: Next AOS 82 32. Over.
CDR: Okay. 82 32.
CMP: Houston, Apollo 11. I am going to start a ma- neuver to P22 attitude at this time.
CC: 11. Roger. We copy. Over. I'a_,,,;015
CMP: Okay. We're noticing _;ome water inside the command module for the first time. There's a little puddle of it on the aft bulkhead sort of like 101 had.
CMP: I'd like to know how EECO_I wants to get rid of it. There are a number of different ways and what does he think is the best one?
CC: We'11 be with you in a moment, Mike. _;tand by.
CMP: No big rush. It will wait until the next REV or two.
CC: Hello, Apollo 1t. Houston. We've played back the LOI-2 burn. It looks really good to us. The systems were all good. We got an orbit on the limited amount of tracking at 65.4 by a 53.9. Over.
CC: Hello, Apollo 11. Houston. We're standing by. Out.
CMP: Okay, Houston. We'11 be done with P22 in just a couple of minutes.
CC: Roger. We copy all that. You're looking good.
CMP: Roger. You copy that NOUN 49 on your downlink? If you've had enough time, I'11 proceed.
CC: We got it. Go ahead, Mike.
CC: Apollo 11, Houston. We see a NODN 89. You can do the VERB 34 now. Over. Beat me to it.
UNKNOWN: Yes. I've done it, Charlie.
CMP: Ail that procedure for P22 seemed to work very well. The only thing that was a little odd, is that there was some DAP thruster activity. I had pitch in ACCEL COMMAND, and roll and yaw in RATE COMMAND, and somehow, roll and yaw got ex- cited and the DAP went into a flurry of thruster firing. We've noticed the same thing in the CMS, and Just written it off as a CMS peculiarity.
CC: Roger. We saw that activity, Mike. We'11 see if we can track it down and let you know. Over.
CC: Apollo I1_ Houston. You can proceed to sleep attitude now. Over.
CMP: That's in work, Houston.
LMP: Houston, this is Apollo ... in the Eagle - Apollo 11 in the Eagle. I've got ... _'or our landing area.
CC: Apollo 11, Houston. You are breaking ap badly. Say again. Over.
CC: Roger. I can see the entire landing area from the position I'm in looking out the left window in the I_4.
CC: Roger, Buzz. Understand you can see t?e entire landing area looking out the LM windows. Over.
CC: Apollo 11, Houston. We got a lot of noise on the downlink. Would you please try your high gain in wide beamwidth, and the angles are 180 the yaw and pitch zero. Over.
CMP: Houston, Apollo 11. How do you read us on the high gain? Over.
CC: Roger, Mike. You're a lot better now. Over.
CMP: Okay. You want a wide beam for some reason?
CC: That's affirmative. We got you in the shadows, though. You are looking right down along the engine bell towards the Earth so we need you in wide beam. Over. Pag_e 248
CMP: Okay. Fine. We're starting our ma_,euvers to sleep attitude. Roll 82, pitch 229, yaw zero.
CC: Roger. The angles you got in the flight plan will he good when you get there.
CC: Go ahead, 11. Over. and
CDR: Okay. We are on page activation 12 13, step 4, and verify descent talkbacks gray, and they' re barberpole.
CC: Apollo 11, Houston. We would like you to take the low voltage taps OFF; RESET, then 0N. Over.
CDR: Stand by. We got it. We just had one circuit breaker out of position.
CDR: We have them gray now.
CC: ... should have warmed up by now.
UNKNOWN: ° Oh, he's transmitting on B.
CDR: Hey, Mike, you transmitting on B?
LMP: Houston, Apollo 11 - Apollo il/Eagle. Over.
CC: Roger, Eagle. This is Houston. We read you. Over.
CC: Roger. I read you about four-by-four. Could you give me a short count, please?

CC: Roger. Are you copying my low bit rate? Over.
CC: Roger. We got some beautiful data here, Eagle. We're - All those guys are looking at it - sys- tems guys. We'11 have some word for you in a minute how everything looks.
CC: Roger. I'm all ready to switch to high bit rate if that's okay with you.
CC: Would you please stand by, Eagle. We want to get to the proper sleep attitude before we proceed on with the COMM check. Over.
LMP: Houston, Eagle. We'11 go ahead with the camera checkout. I'm still on low taps, and I assume there's no problem doing that. Over.
CC: That's affirmative. No problem on that, Eagle. You can go ahead and power up the sequence camera. Over.
LMP: Should have done that before.
CC: Eagle, be advised - sounds like a hot mike. Over.
LMP: Right. Yes.
LMP: Roger. If you're reading me now, I am in hot mike because I'm in iCS push to talk, snd DOWN- VOICE BACKUP. Over.
CC: Roger. We just wanted to remind you. Over.
CC: Columbia, this is Houston. Are you ma_leuvering to sleep attitude? Over.
CC: Eagle, this is Houston. We have lost ell the voice and data with Columbia. Would you see if he is maneuvering to sleep attitude? Over.
LMP: Hey, Mike. You maneuvering to sleep attitude?
UNKNOWN: I don't believe they can hear you, Mike. Are you maneuvering now to sleep attitude?
LMP: Houston, Eagle. The Columbia has maneuvered to sleep attitude. He's got the high gain antennas - antenna angles set in, and he should be cnmmuni- cating with you. Over.
CC: Roger. We don't have him. Stand by.
CC: Eagle, Houston. Would you please have Columbia put in COMMAND RESET? Over.
CMP: Wilco. COMMAND RESET.

CC: Roger, Eagle. This is better than the downvoice backup. Stand by 1.
CC: Eagle, Houston. Everybody's happy as a elam with this mode. We'd like to stay here for a little bit. Telemetry looks great, and the; voice is great. Over.
LMP: Roger. Understand. I'm checking out camera number 4 now.
CC: Eagle, Houston. Say again what you're checking out? 0vet.
LMP: Roger, Houston. Eagle has checked out both 70-millimeter cameras and both 16-millimeter cameras, and all work fine. Over.
CC: Sounds great. Stand by.
CC: Eagle, Houston. We've looked over your systems on the high bit rate. Everything looks super; we're ready to go. Over.
LMP: Roger. Stand by. YOll want to go back to low bit rate now?
CC: Stand by on that. Over.
CC: Eagle, Houston. We look good through tae 210 on this mode. We're going to shift data select to an 85-foot dish to see what we've got, and then we'11 be back to you on the 210. If you'11 stand by a couple of minutes in this mode, we'11 be back with you. Over.

CC: Eagle, this is Houston coming through the 2]0. How do you read? Over.
CC: Eagle, this is Houston. We're happy with all our data in all modes. You can power down the COMM now. Over.
LMP: Roger. I understand. Eagle will power down the COMM, and we are Just approaching 27 volts now. It looks like we won't have to bother with the high taps.
LMP: We're powering down. Out.
CC: Columbia, this is Houston. We got a TEIll PAD for you and an update on the water dump. Over.
CMP: Stand by one, Houston. Are you through with the D_KY?
CMP: Houston, Columbia. Ready to copy TEI Il. Over.
CC: Roger, Columbia. Here we come with the TEIll. SPS G&N: 37200, minus 060, plus 047. NOUN 33, 098 05 2422, plus 41448, plus 03719, minus 02422. Roll is NA, pitch 020, the rest of the PAD is NA. Set stars are NA. The ullage is two quads - correction, two Jets for 16 seconds; use Bravo and Delta. In the comments, the undocked present CSM- correction, this is for -TEI 11 is undocked. Present onboard weight of the CSM is 37200 pounds, about 50 Alfa on your DAP. Over.
CMP: All right. I read back: TEI 11, SPS G&N: 37200, minus 060, plus 047, plus 098, 05 2422, plus 41448, plus 03719, minus 02422; NA, 020; the rest of the PAD NA. Ullage, two Jets for 16 seconds, Quads B and D. Undocked present CSM weight is okay in the DAP.
CC: Roger, 11. And we'd like you to do a waste-water dump at 84 hours down to 25 percent. Over.
CMP: Roger. I understand. Waste-water dum_ to 25 per- cent at 84 hours.
CC: Roger. And, Mike, we'11 have LOS in about 11 _nutes at 83 44. AOS is 84 30, and prior to - or at LOS, we would like you to go - Configure the S-band for high gain track to REACQ, high gain beam to NARROW, and let's try that to see if we can get an automatic REACQ at the next AOS. Over.
CMP: I'm in REACQ and NARROW now.
CC: Apollo 11, Houston. Also, that water that you got on the aft bulkhead, we - If it's not too much, we Just recommend sopping it up and then throwing the sponges away in the waste stowage area. If it's too much, then we recommend using the proce- dure in the checklist on page Fl0-14. Over.
CC: Apollo 11, Houston. Would you have Buzz make sure he gives us the OPS pressure readings before you close up? Over.
CDR: Houston, 11. The OPS read 5750, both bottles.
CC: 11, Houston. Roger. Reading you fine, and it looks like the automatic REACQ went very well just as soon as you came around the limb. We have several small items to discuss with you here just before you go to sleep. Over.
CC: Okay, 11. First of all, on our LM systems checks, everything went fine. I would like to remind you, though, tomorrow you may see an ascent pressure light when you activate the MC&W. There should be no problem, however. You did note that the APS AUX tank pressure was only re_ding lll psi, which is normal at this point, but below the level which will trigger your light due to the helium which has been dissolved into the propellant. Over.
CMP: Roger. Understand that. Thank you. And
CC: Roser, next item, the supercritical helium rise rate is nominal, and you also had that question for us about your thruster activity during the P22 on the l_st REV. Believe we understand that now, as yOU reported that your pitch was in ACCEL COMMAND and your yaw and roll were in RATE COMMAND. You were firing your pitch thrusters. This will couple _tes into your yaw and roll axes, and the - You were at that time holding only half a degree dead- ba_3_ and coupling rates into yaw and roll produced the extra firings about the yaw and roll axes. Over.
CMP: Yes. That may be true. It's very peculiar coupling, in %hat it waits longer than you would think and its l'e_ction is greater than you would think. We were getting yaw rates of around four-tenths of a degree per second, for example.
CC: Roger, Mike. We did play the data back, and that's the way it looked upon analysis of the chart record- ings back here. Over.
CC: They've also looked at the results of your landmark tracking. The marks all apparently were very good, and we've got a full page of data here relative to the altitudes of the various site locations, which I won't read up to you, but I did want to let you know that the marks apparently went very well. I also have your consumable budgets, particularly your RCS propellant quantities. They're Deltas from nominal if you should want them. Your worst quad is quad Charlie, which is 9 percent low. I'11 not read up the others unless you want them. Over.
CMP: Okay. How about the 02 fuel cell purge? You want that now?
CC: I'11 have to stand by Just a moment.
LMP: Okay. And then the other one is, we're still charging battery A.
CC: 11, Houston. We would like to delay the fuel cell purge until the backside of the Moon, and you go ahead and - should terminate your battery charge at this time. Over.
LMP: Okay. Understand. I knew we had another 02 and H2 purge coming up in the morning; I wasn't sure whether you wanted to go through with this one or not. I'11 wait until the next side and then do it.
CC: That's fine, Buzz.
LMP: Terminate battery charging now.
CC: That's right, and one other systems item here - in or,er to balance your CRYO tanks, would you get your 02 tank i and your H 2 tank 2 heaters off? Over.
CMP: Okay. I have 02 tank heater 1 off, and H2 tank heater 2 off.
CC: That's right, Mike, and we believe you have your quad Bravo and quad Charlie turned off in your DAP at this time, and a 5-degree deadband. We'd prefer a lO-degree deadband for your sleep period overnight here. Over.
CC: One other item relative to a malfunction procedure. It's unlikely that you'11 have to worry about this tomorrow, but in your malfunction list under docking on page Fll-9, there is a malfunction procedure for a high OR flow rate at the top of - under tunnel at the top of page 11-9. We would like to have you not use that malfunction procedure should you encounter the high 02 flow rate, and instead, check back with Houston for a revised procedure should you find that situation. Over.
CMP: Understand, and note has been made in my checklist.
CC: 11, Houston. Roger. That Just about takes care of all the items we have here on the ground before time to hit the sack, and I guess you will have a presleep check for us before you go to bed.
CC: Roger. We're in the midst of cycling the 0_ and H2 fans now.
CC: And the radiation is as follows: CDR 11012, CMP 100lB, _ 09015. Negative medication. Over.
CC: Roger. We're thinking about taking the monocular with us on into the LM. We think it m'ght prove to be of some use. Over.
CC: Roger, Buzz. It sounds like a good idea for some of yo_r surveying work there inside the cockpit. Over.
CC: Okay. You want to run that by with whoever might be concerned?
CC: I sure will.
CC: Apollo 11, Houston. We have apparently lost the high gain lock. We would appreciate it if you would give us a help manually to try to relock up on the high gain. Over.
LMP: Houston, Apollo 11 ....
CC: 11, Houston. Reading you very weak, still too far down in the noise to complete the full trausm/ssion. If you'd give us a hand on a manual reloek, we'd appreciate it.
CC: Apollo 11, Houston. We're still unable to pick you up on the high gain antenna. Request you go to MANUAL, and wide beamwidth. The pitch and yaw angles in your checklist are good ones. You should be able to find us there. Over.
LMP: Houston, Apollo 11. How do you read now?
CC: 11, Houston. Loud and clear this time. How me?
LMP: Loud and clear. You faded out on your last transmission. Over.
CC: Roger. Are you in wide bes:n now?
LMP: Negative. I got you locked back on again REACQ and narrow.
CC: Roger. _lat's all we want. We want to stay in narrow, and we're a little puzzled _)out why we lost you here a few minutes ago. Do you have any ideas?
UNKNOWN: No, we sure don't (cough) - sure don't. We're showing - we're showing about 15 degrees plus pitch and about 270. That ought to be good and clear.
CC: We concur there. We still don't have any good ideas on why we were lost then.
CC: 11, Houston. Would you confirm that we did acquire automatically when you came around the limb for this passage. Over.
LMP: That's confirmed. Thenk
CC: 11, Houston. On your AUTO RCS SELECT switches, we show quad Bravo disabled but quad Charlie only partially disabled. Charlie 3, I believe, is the only one you have selected off. Is that correct?
CMP: Yes. Roger. That's correct.
CMP: How do they look to you now, Houston?
CC: 11, Houston. We see them all disabled at this time. Thank you.
CC: 11, Houston. We're going to try to check out this ability to automatically reacqulre on the S-band, and what we want to do i_: to secure our uplink carrier for about 30 seconds. Then we will turn it back on and see if the space- craft equipment will automatically reacquire. So if you do not get a call from us within about 3 minutes, that means we have not been able to reacquire and request your assistance on a manual acquisition. Over.
UNKNOWN: We understand.
CC: 11, Houston. We also would apprecia:;e - if you will note the angles that the antenna tracks through in its attempt to reacquire. Over.
LMP: Roger. We'11 do that.
CC: 11, Houston. It looks like we're locked back up again with no delay. How does it look on board? Over.
LMP: Roger. The signal strength dropped very rapidly to zero; and the pitch and yaw, in about 3 sec- conds, moved toward 40 degrees pitch and 240 degrees yaw. Right now, they're sitting on about 15 degrees pitch and about 265 degrees yaw. So they didn't move very far, about 30 degrees apiece; and then they picked right back on up again. Over.
CC: Roger. Some of "The Luckiest People" in the background there. We copied your pitch and yaw angles.
CC: 11, Houston. Could you give us the location of your - pitch and yaw location of your posi- tion indicators? Over.
LMP: Roger. They're in the same position as the antenna right now; plus 15 degrees pitch and - no, now wait a minute. I got them - got it at about 275 instead of 265.
CC: 11, Houston. We'd like to try the same procedure once more. We'11 leave the carrier a little longer and be back up for a call within 4 minutes. Over.
CC: 11, Houston. We're locked back up a_ain. Can you give us a report on how the antenna behaved?
LMP: Roger. It was essentially identical as before. The pitch went to 45, 40 to 45 s_ld the yaw went to about - to about 255, 245 to 255; and then it rather quickly locked up at 15 degrees pitch and 270 yaw. Over.
CC: 11, Houston. Roger. Your angles are 45 and 255. Do I understand that as soon as the car- rier dropped, it went to these angle _; or did it only go to these angles after the uplink carrier was reenabled and the antenna began to reacquire? Over.
LMP: No. As soon as the carrier dropped off, why, it drifted over into those angles anti stayed there. Then when it came back up again, why, hunted it around for a while, but it didn't get any further off. Gradually brought it on in to the angles where it is right now; and then the signal strength would take several Jumps as evidently it goes from wide to medium to narrow. Over.
CC: 11, Houston. Understand. And on ancther sub- Ject, request you zero your optics for the night. Over.
LMP: Roger. Zeroed.
CC: Apollo 11, Houston. Can you confirm that you have changed the C02 filter as per flight plan in the last hour? Over?
CMP: No. We're still eating. We're about to do it. We'11 let you know.
CC: Roger, 11. And we've got about 14 minutes until LOS. AOS is 86 30, an hour away. We're won- dering whether or not you plan to have one man up at that time or would you all like to be asleep inside the next hour? Over.
CMP: Somebody will be up.
CC: Roger. The thing that we're still puzzling on is the antenna, and if - as long as there will be somebody up, why, we would like to have somebody check the automatic REACQ on the next AOS.
