Neil Armstrong (CDR)

I cycled the circuit breaker and got all nines. And we'll not now reset from all nines.

Charlie Duke (CAPCOM)

Tranquility, Houston. We'll research this problem and be back with you momentarily on the mission event time—correction, the mission timer.

Neil Armstrong (CDR)

I'd say the color of the—The local surface is very comparable to that we observed from orbit at this Sun angle, about 10 degrees Sun angle, or that nature. It's pretty much without color. It's gray, and it's a very white, chalky gray, as you look into the zero phase line; and it's considerably darker gray, more like a ash—ashen gray as you look out 90 degrees to the Sun. The—Some of the surface rocks in close here that have been fractured or disturbed by the rocket engine plume are coated with this light gray on the outside; but where they've been broken, they display a dark—very dark gray interior; and it looks like it could be country basalt.

Charlie Duke (CAPCOM)

Roger, Tranquility. We see the NOUN 93, VERB 34.

Buzz Aldrin (LMP)

Roger. I assume you wanted it. Roger.

Charlie Duke (CAPCOM)

Tranquility, Houston. Please vent fuel and OX again. Over. It's building back up.

Charlie Duke (CAPCOM)

Tranquility, Houston. You can open both fuel and OX vent now. Over.

Buzz Aldrin (LMP)

Houston, Tranquility standing by for GO on a AGS to PGNS align and a lunar align. Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. You are GO for the AGS to PGNS align and a lunar align. Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. Please vent the fuel. It's increasing rapidly. Over.

Neil Armstrong (CDR)

We show 30 psi in the fuel and 30 in the oxidizer.

Charlie Duke (CAPCOM)

Roger. We're reading somewhat different than that. Stand by.

Neil Armstrong (CDR)

The fuel temperature is reading 64 in the descent, and the oxidizer—that's descent 2—and the oxidizer is off scale low. Descent 1 is showing 61 in the fuel and 65 in the oxidizer.

Charlie Duke (CAPCOM)

Roger. Stand by. Tranquility, Houston. Please take the fuel vent switch and hold it open. Over.

Neil Armstrong (CDR)

Okay. We're holding it open. Indicating about 24 psi on board.

Neil Armstrong (CDR)

Now indicating 20 psi in the fuel side.

Buzz Aldrin (LMP)

Now indicating 15 psi in both tanks.

Charlie Duke (CAPCOM)

Tranquility, Houston. If you haven't done so, you can release the fuel vent switch now. Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. We have indication that we've frozen up the descent fuel helium heat exchanger, and there's some fuel trapped in the line between there and the valves; and the pressure we're looking at is increasing there. Over.

Charlie Duke (CAPCOM)

Tranquility Base, Houston. If you have not done so, please close both fuel and OX vents now. Over.

Neil Armstrong (CDR)

From the surface, we could not see any stars out the window; but out my overhead hatch, I'm looking at the Earth. It's big and bright and beautiful. Buzz is going to give a try at seeing some stars through the optics.

Charlie Duke (CAPCOM)

Roger, Tranquility. We understand. Must be a beautiful sight. Over.

Charlie Duke (CAPCOM)

Columbia, Houston. Two minutes to LOS. You're looking great going over the hill. Over.

Michael Collins (CMP)

Okay. Thank you. Glad to hear the system's looking good. You have a suggested attitude for me? This one here seems all right.

Michael Collins (CMP)

Let me know when it's lunch time, will you?

Charlie Duke (CAPCOM)

Columbia, Houston. You got a good attitude right there.

Charlie Duke (CAPCOM)

Tranquility Base, Houston. If you want me to, I can give you a hack on the mission time, every 30 minutes. Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. I'm counting down to T3 time. If you'd like to give me a hack, we can set up an event timer. Over.

Buzz Aldrin (LMP)

Okay. How about counting up?

Charlie Duke (CAPCOM)

Roger. You want it counting up? Stand by.

Charlie Duke (CAPCOM)

Tranquility, Houston. On my Mark, 62 30.

Buzz Aldrin (LMP)

What we're looking for, Charlie, is the time counting up to T2 that'll be equal to 60 minutes—or T3, be equal to 60 minutes on T3.

Charlie Duke (CAPCOM)

Roger. We'll have it for you.

Charlie Duke (CAPCOM)

Tranquility Base, Houston. Reset the event timer to zero and on my Mark at 103 39 41. We'll give you a hack, and it'll be 1 hour. Over.

Charlie Duke (CAPCOM)

And we've got about—almost 3 minutes to go, Neil. Over.

Charlie Duke (CAPCOM)

Tranquility Base, stand by on the event timer.

Charlie Duke (CAPCOM)

Tranquility Base, Houston. On my Mark start your event timer.

Neil Armstrong (CDR)

Roger. We got it; thank you.

Charlie Duke (CAPCOM)

Roger, Neil.

Charlie Duke (CAPCOM)

Tranquility, Houston. We see the star angle difference. Looks good.

Buzz Aldrin (LMP)

Okay. That last star was Navi, and it wasn't too well distinguishable. I can see where that error could come in. I think for the gravity alignment with one star, Rigel will be quite good.

Charlie Duke (CAPCOM)

Roger. Stand by on the NOUN 93.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. We'd like you to torque that. Over.

Neil Armstrong (CDR)

Houston, this is Tranquility. Do you want us to accept this position? Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. We're looking at it. Stand by. We'd like you to pull the circuit breaker on panel 11 for the mission timer. Over.

Neil Armstrong (CDR)

Roger. I've already done that, Charlie.

Charlie Duke (CAPCOM)

Tranquility, Houston. We'd like you to reject that RLS. Over.

Charlie Duke (CAPCOM)

And, Tranquility Base, Houston. We'd like you to call—after this, call P00, and give us a E memory dump.

Buzz Aldrin (LMP)

Okay. Here comes the E memory dump.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. Did I copy PROGRAM ALARM 1106 from you? Over.

Buzz Aldrin (LMP)

Roger. That' s affirmative.

Buzz Aldrin (LMP)

Could that, by any chance, be due to the fact that I flashed the updata link switch to DATA while that was going on? Over.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. The SPAN guys think that's conceivable. Stand by. I think we want another VERB 74.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. We'd like another VERB 74. Over.

Charlie Duke (CAPCOM)

Tranquility Base, Houston. On my Mark it will be GET 103 53.

Charlie Duke (CAPCOM)

103 53—correction, 54.

Charlie Duke (CAPCOM)

Hello, Tranquility. Houston. We have the LM ascent PAD. If you're ready to go. Over.

Buzz Aldrin (LMP)

Roger. Ready to copy the LM ascent PAD.

Charlie Duke (CAPCOM)

Roger, Tranquility. TIG, 104 39 47 00, 55358 00322, plus 0022. DEDA 47, plus 37130, minus 70615, plus 58620, plus 56936. Over.

Buzz Aldrin (LMP)

Roger. LM ascent PAD: 104 39 47 00, 55358 00322, plus 0022, plus 37130, minus 70615, plus 58620, plus 56936. Over.

Charlie Duke (CAPCOM)

Roger, Tranquility. Good readback. We also have a CSI PAD if you are ready to copy.

Buzz Aldrin (LMP)

Okay. We are ready to go.
