Spacelog Apollo 11

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.

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.
