Spacelog Apollo 11

There's a good picture of Boot Hill.

Roger. We're —

Three minutes and 15 seconds into the descent.

Roger. We're seeing Boot Hill now.

The next crater coming into the bottom, that's Duke Island right there, and to the left, the crater—the largest of the craters near the center of the picture right now is Maskelyne W. This is a position check during descent at about 3 minutes and 39 seconds, and it's our down range position check and cross range position 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.

Roger. I imagine you'll get a—you'll get a real good look at that tomorrow afternoon.

Sinuous Rille is the one that was referred to in Apollo 10 as Sidewinder.

That's a good name, too: Sidewinder and Diamondback. It looks like a couple of snakes down there in a lake bed.

And we're approaching the terminator now. See the —

Roger.

Contrast has increased and only the sunlit side of these ridges remain illuminated, while the dark sides and the shadow will become completely black.

11, this is Houston. The picture's getting a little grainy now. You might go ahead and open up the f stop.

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.

Roger. We can just see; it looks like a little less than half of its rim right now.

And we can make out just barely some features on the surface, maybe from earthshine.

Are you wide open on the f stop at this time?

Yes, we are.

Yes. And it looks like we're just about to get the Sun coming into the lens, so we'll have to move the camera away.

Roger.

We can't see any earthshine or any surface features at all in earthshine now due to the fact that the LM 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'll 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.

Yes. It's a very beautiful and a rugged sight that we've got on the screen now.

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.

Roger. I have a comment here that says that's what the LM was built for.

I believe!

And as the Moon sinks slowly in the west, Apollo 11 bids good day to you.

Roger. We sort of thought it was the Sun setting in the east.

Well, it depends on your point of view.

Roger. Out.

Apollo 11, Houston. When you're ready to copy, I have an LOI 2 PAD and a TEI 5 PAD. Over.

Okay. Stand by.

I'm passing 182 inertial. I'm going inertial now.

Ready to copy LOI 2 PAD.

Roger, LOI 2: SPS/G&N: 38320, plus 166, minus 081 080 11 3603, minus 01408, minus all balls, minus 00743, all zeros, 196 359 00657, plus 00537, 01592 017 01531 23 1160 138. Vega, Deneb 243 183 012, two jet 19 seconds, DAP, R1 20101. Sextant star between 79 30 10 and 79 52 10. Attitude is heads down, retrograde pitched up 28 degrees. HA after the burn—Was that NOUN 42 for HA and 64.6 and HP 54.6? Over.

Roger. On the NOUN 42 value, the last stuff you gave, HA is 65.6, HP is 54.6. Otherwise, I readback correct. I'm standing by with your TEI 5 PAD. Over.

Roger. HA 65.6 for NOUN 42. And ready to copy.

11, this is Houston. TEI 5 SPS/G&N: 37201, minus 060, plus 047; TIG 086 09 3666. NOUN 81: plus 33521, plus 03441, minus 01458; roll NA, pitch 032. The rest of the PAD is NA. Ullage two jet, 16 seconds undocked. Over.

Roger. TEI 5 SPS/G&N: 37201, minus 060, plus 047 086 09 3666, plus 33521, plus 03441, minus 0145 458, NA, 032. The rest is NA. Two jet, 16 seconds, undocked. Over.

Apollo 11, this is Houston. Readback is correct. Out.

Apollo 11, this is Houston.

Houston, you want us back on downvoice backup? Over.

Apollo 11, this is Houston. That's affirmative on the downvoice backup. We'd like you to confirm your UPTELEMETRY switch in the NORMAL position. Over.

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?

That's affirmative.

Thank you.

And what I'm asking for is the switchover to —

The UPTELEMETRY switch is in NORMAL. Over.

Apollo 11, this is Houston. Over.

Go ahead, Houston.

Roger. During the LOI 1 burn, your engine 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.

Okay.

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 long story short, it worked its way up to 100.

Roger.

And down here, we showed a chamber pressure of on the order of 103 to 104 psi during your burn on playback.

Okay.

Go ahead with the TEI 4.

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 seconds, undocked. No LOI 2. Over.

Just in TEI 4 SPS/G&N: 38320, minus 055, plus 060 084 30 2749, plus 31380, plus 03475, minus 01032, NA, 034. All the rest of the PAD's NA. Two jets, 16 seconds, undocked. No LOI 2.

Apollo 11, this is Houston.

Roger. Go ahead, Houston.

Roger. We've been looking at your systems data on playback, and everything is looking good. In particular, the SPS 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.

Well, we didn't have any plans to. No. We just wanted to be ready at that time.

Roger. We just wanted to make sure that we were ready when you were ready. Over.

Okay. And to get the sextant star in LOI 2, that's roll zero. Is that affirmative?

That's affirmative. Roll zero.

Apollo 11, Houston. Five minutes until LOS. And with respect to your request for the nitrogen bottle pressures preburn, just before the burn, we were showing 2270 pounds per square inch on bottle Alfa and 2350 on bottle Bravo. Over.

Apollo 11. Roger. Thank you.

Apollo 11, this is Houston. Two minutes to LOS. Your AOS on the other side is 80 33 21, and the friendly White Team will see you when you come out from behind the Moon.

Apollo 11. Roger.

Thank you, Bruce.

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.

Okay. I don't blame you, Hank.

Hello, Apollo 11. Houston. We're standing by. Over.

VGY minus 0.0, VGZ minus 0.1, DELTA-VC minus 5.2, fuel 362, OX 364, unbalance plus 50, and our postburn now 94's, 66.1 by 54.4. Go ahead.

Roger. We copy, Neil. Would you say again the DELTA-VZ? We missed that. Over.

Roger. That was minus 0.1.

Roger. Copy the burn report. Sounds good.

And all looked good up here.

Apollo 11, Houston. We missed your DELTA-TIG and also your DELTA burn time. Over.

DELTA-TIG was zero and the burn time was 17 seconds.

Copy 17.

Apollo 11, Houston. We'll be satisfied if you pump up the cabin to 5.4. Over.

Okay. We're showing about 5.2 right now.

Roger.

And, Charlie, the LM/CM DELTA-P is just over 1 pound right now.

Apollo 11, Houston. Over.

Hello, Apollo 11. Houston. Over.

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.

Hello, Apollo 11, Apollo 11.

Roger.

Roger. We're reading you five by. Go ahead. Over.

Roger. We have you on high gain now.

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.

Okay. We're pressurizing the LM at this time.

Hello, Apollo 11. Houston. We have a P22 AUTO optics update for you if you're ready to copy. Over.

Ready to copy.

Roger, Mike. It's landmark Alfa 1: T1, 82 37 35; T2, 82 42 50. We're 7 miles north. Over.

Copy. P22: T1, time 82 37 35; T2, 82 42 50. And the target is 7 miles north. Thank you.

I get the distinct impression, Charlie, that mare there laps up over the edge of the mountains at the shorelines.

Roger. We copy.

Houston. On your comment about the mare lapping up to the terrain—mountainous terrain, is that an impression like a lava flow coming in around a prominence, Neil, or is it more -looks like it's sloping up at that point? Over.

It isn't true everywhere, but there's certainly places where there seems to be a slope downward towards the shoreline on the mare. In other words, from the mare down to the shoreline is a downward slope indicating that it might be a lava flow.

Roger.

Crossing Duke Island and Maskelyne W.

Say again, Neil. Over.

We just crossed Duke Island and Maskelyne W.

Hello, Apollo 11. Houston. We're wondering if you've started into the LM yet. Over.

We have the CSM hatch out, the drogue and probe removed and stowed, and we're just about ready to open the LM hatch now.

Okay, Charlie. We're in the LM. The docking index mark is the same.

Roger. We copy.

Charlie, apparently there just doesn't seem to be any slow way to get that REPRESS to AUTO without making a big bang.

Apollo 11, Houston. Say again. Over.

Roger. There just doesn't seem to be any slow way to get the REPRESS closed to AUTO and avoid a big bang. Over.

We copy, Buzz. Thank you much. Out.

We concur with that, Buzz.

Apollo 11, Houston. We'll have LOS 81 45, next AOS—Stand by.

Next AOS 82 32. Over.

Okay. 82 32.

Houston, Apollo 11. I am going to start a maneuver to P22 attitude at this time.

11. Roger. We copy. Over.

Okay. We're noticing some 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.

Roger.

I'd like to know how EECOMM wants to get rid of it. There are a number of different ways and what does he think is the best one?

We'll be with you in a moment, Mike. Stand by.

No big rush. It will wait until the next REV or two.

Hello, Apollo 11. 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.

Hello, Apollo 11. Houston. We're standing by. Out.

Okay, Houston. We'll be done with P22 in just a couple of minutes.

Houston, Apollo 11.

Go ahead.

Roger. You copy that NOUN 49 on your downlink? If you've had enough time, I'll proceed.

Apollo 11, Houston. We see a NOUN 89. You can do the VERB 34 now. Over. Beat me to it.

Yes. I've done it, Charlie.

Roger.

Houston, Apollo 11.

Go ahead, 11. Over.

All 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 excited 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.

Roger. We saw that activity, Mike. We'll see if we can track it down and let you know. Over.

Okay.

Apollo 11, Houston. You can proceed to sleep attitude now. Over.

That's in work, Houston.

Okay.

Houston, we're holding inertial a little while to study the approach to the landing zone.

Houston, this is Apollo … in the Eagle—Apollo 11 in the Eagle. I've got … for our landing area.

Apollo 11, Houston. You are breaking up badly. Say again. Over.

Roger. I can see the entire landing area from the position I'm in looking out the left window in the LM.

Roger, Buzz. Understand you can see the entire landing area looking out the LM windows. Over.

That's right.

…

Apollo 11, Houston. Say again. Over.

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.

Houston, Apollo 11. How do you read us on the high gain? Over.

Roger, Mike. You're a lot better now. Over.

Okay. You want a wide beam for some reason?

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.

Okay. Fine. We're starting our maneuvers to sleep attitude. Roll 82, pitch 229, yaw zero.

Houston, 11.

Go ahead, 11. Over.

Okay. We are on page activation 12 and 13, step 4, and verify descent talkbacks gray, and they're barberpole.

Roger. Stand by.

Apollo 11, Houston. We would like you to take the low voltage taps OFF; RESET, then ON. Over.

Stand by. We got it. We just had one circuit breaker out of position.

Okay.

We have them gray now.

… should have warmed up by now.

Oh, he's transmitting on B.

Hey, Mike, you transmitting on B?

Houston, Apollo 11—Apollo 11/Eagle. Over.

Roger, Eagle. This is Houston. We read you. Over.

Roger. I read you about four by four. Could you give me a short count, please?

Roger, Eagle. Coming in with the short count—1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Houston out. Over.

Roger. Are you copying my low bit rate? Over.

Roger. We got some beautiful data here, Eagle. We're—All those guys are looking at it—systems guys. We'll have some word for you in a minute how everything looks.

Roger. I'm all ready to switch to high bit rate if that's okay with you.

Would you please stand by, Eagle. We want to get to the proper sleep attitude before we proceed on with the COMM check. Over.

Standing by.

Houston, Eagle. We'll go ahead with the camera checkout. I'm still on low taps, and I assume there's no problem doing that. Over.

Stand by.

That's affirmative. No problem on that, Eagle. You can go ahead and power up the sequence camera. Over.

Should have done that before.

Eagle, be advised—sounds like a hot mike. Over.

Right. Yes.

Roger. If you're reading me now, I am in hot mike because I'm in ICS push to talk, and DOWNVOICE BACKUP. Over.

Roger. We just wanted to remind you. Over.

Thank you.

Columbia, this is Houston. Are you maneuvering to sleep attitude? Over.

Eagle, this is Houston. We have lost all the voice and data with Columbia. Would you see if he is maneuvering to sleep attitude? Over.

Hey, Mike. You maneuvering to sleep attitude?

…

I don't believe they can hear you, Mike. Are you maneuvering now to sleep attitude?

…

Houston, Eagle. The Columbia has maneuvered to sleep attitude. He's got the high gain antennas—antenna angles set in, and he should be communicating with you. Over.

Roger. We don't have him. Stand by.

Eagle, Houston. Would you please have Columbia put in COMMAND RESET? Over.

Wilco. COMMAND RESET.

Eagle, Houston. Since we're in sleep attitude, I'll give you another long count. If you're reading in this mode, we'd like you to switch to high bit rate. Over.

Roger. Go ahead with your short count.

Roger. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. We're reading you five by. You can go to high bit rate now. Over.

Roger. Going to high bit rate now.

Eagle, this is Houston. Do you read? Over.

Houston, this is Eagle. Roger. Read you loud and clear. How me? Over.

Roger. Reading you five by also, Buzz, and we got the high bit rate. It's looking beautiful through Goldstone. Giving you a count: 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Please give us a count. Over.

Roger, Houston. Eagle with a count. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Over.

Roger. Stand by. We're reading you five by. Over.

Okay. I'm ready to go S band voice. Over.

Stand by, Eagle. Stand by on step 4.

Columbia, this is Houston. Would you please give us P00 in ACCEPT. We've got a load for you. Break. Eagle, we're ready to go to step 4. Please select S band voice to VOICE. Over.

Hello, Eagle. This is Houston. How do you read—normal voice? Over.

Eagle—Houston, this is Eagle. Read you loud and clear on S band, normal voice. How me? Over.

Roger. You're beautiful in this mode, Buzz. We're reading you five by. Coming with a short count and we'd like one back from you. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Houston out.

Roger. Houston, Eagle. You're gorgeous also. 1, 2, 3, 4, 5; 5, 4, 3, 2, 1. Eagle, over.

Roger, Eagle. This is better than the downvoice backup. Stand by 1

Eagle, Houston. Everybody's happy as a clam with this mode. We'd like to stay here for a little bit. Telemetry looks great, and the; voice is great. Over.

Roger. Understand. I'm checking out camera number 4 now.

Eagle, Houston. Say again what you're checking out? Over.

Roger, Houston. Eagle has checked out both 70 millimeter cameras and both 16 millimeter cameras, and all work fine. Over.

Sounds great. Stand by.

Eagle, Houston. We've looked over your systems on the high bit rate. Everything looks super; we're ready to go. Over.

Roger. Stand by. You want to go back to low bit rate now?

Stand by on that. Over.

Eagle, Houston. We look good through the 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'll be back to you on the 210. If you'll stand by a couple of minutes in this mode, we'll be back with you. Over.
