Charlie Duke (CAPCOM)

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

Charlie Duke (CAPCOM)

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

Buzz Aldrin (LMP)

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.

Michael Collins (CMP)

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.

Charlie Duke (CAPCOM)

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

Michael Collins (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.

Charlie Duke (CAPCOM)

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

Michael Collins (CMP)

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

Charlie Duke (CAPCOM)

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

Michael Collins (CMP)

Well, it depends on your point of view.

Charlie Duke (CAPCOM)

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

Michael Collins (CMP)

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

Buzz Aldrin (LMP)

Ready to copy LOI 2 PAD.

Charlie Duke (CAPCOM)

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 00743. Roll all balls, 196 359 00657, plus 00537. DELTA-VT 01592 017 01531. Sextant star 23 1160 138. The rest of the PAD is NA. GDC align, Vega and Deneb 243 183 012. Ullage, two jets 19 seconds. Remarks: On your DAP load, we would like an R1 20101 vice the value which appears in the flight plan. In making the sextant star check 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 orientation is heads down, retrograde pitched up 28 degrees with respect to local horizontal. The calculated values for NOUN 42 are HA 65.6 and HP 54.6. Both of those being plus. Read back. Over.

Buzz Aldrin (LMP)

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.

Charlie Duke (CAPCOM)

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.

Buzz Aldrin (LMP)

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

Charlie Duke (CAPCOM)

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.

Buzz Aldrin (LMP)

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.

Charlie Duke (CAPCOM)

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

Charlie Duke (CAPCOM)

Apollo 11, this is Houston.

Michael Collins (CMP)

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

Charlie Duke (CAPCOM)

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.

Michael Collins (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?

Charlie Duke (CAPCOM)

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

Michael Collins (CMP)

The UPTELEMETRY switch is in NORMAL. Over.

Charlie Duke (CAPCOM)

Apollo 11, this is Houston. Over.

Charlie Duke (CAPCOM)

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.

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

Charlie Duke (CAPCOM)

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

Buzz Aldrin (LMP)

Go ahead with the TEI 4.

Charlie Duke (CAPCOM)

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.

Buzz Aldrin (LMP)

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.

Charlie Duke (CAPCOM)

11, this is Houston. Readback correct. Out.

Charlie Duke (CAPCOM)

Apollo 11, this is Houston.

Buzz Aldrin (LMP)

Roger. Go ahead, Houston.

Charlie Duke (CAPCOM)

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.

Buzz Aldrin (LMP)

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