Neil Armstrong (CDR)

Roger. Got 3.8 and I got 54 on the O2 and no flags, and my flow is in N.

Bruce McCandless (CAPCOM)

Neil and Buzz, for your information, your consumables remain in good shape. Out.

Buzz Aldrin (LMP)

Roger, How's it coming, Neil?

Neil Armstrong (CDR)

Okay. I've got one side hooked up to the second box and I've got the film pack on.

Neil Armstrong (CDR)

Boy, that bilge from on the LEC is kind of falling all over me while I'm doing this.

Neil Armstrong (CDR)

That's what it looks like down here.

Buzz Aldrin (LMP)

I think my watch stopped, Neil.

Buzz Aldrin (LMP)

No, it didn't either. Second hand.

Buzz Aldrin (LMP)

Okay. If you can just kind of hold it, why, I think I can do the pulling.

Neil Armstrong (CDR)

Okay. Stand by a minute. Let me move back.

Buzz Aldrin (LMP)

Okay. Easy. All right, easy in the hatch now.

Buzz Aldrin (LMP)

Okay. I'll get it the rest of the way. And I'll give it to you to—No, wait, just a second. Yes, a little more.

Neil Armstrong (CDR)

How about that—package out of your—brief. Get that?

Neil Armstrong (CDR)

Okay. I'll get it when I get up there.

Bruce McCandless (CAPCOM)

Neil, this is Houston. Did you get the Hasselblad magazine?

Neil Armstrong (CDR)

Yes, I did. And we got about, I'd say, 20 pounds of carefully selected, if not documented, samples.

Bruce McCandless (CAPCOM)

Houston. Roger. Well done. Out.

Buzz Aldrin (LMP)

Just keep your head down close. Now start arching your back. That's good. Plenty of room. Now, all right, arch your back a little, your head up against *** Roll right just a little bit. Head down. … in good shape.

Neil Armstrong (CDR)

Thank you. Am I bumping now?

Buzz Aldrin (LMP)

No, you're clear. You're rubbing up against me a little bit.

Buzz Aldrin (LMP)

*** All right. That's right. A bit to the left. Okay. Now move your foot, and I'll get the hatch.

Buzz Aldrin (LMP)

Okay. The hatch is closed and latched, and verified secure.

Neil Armstrong (CDR)

Okay. Now we turn the feedwater valve—CLOSED. And I got your PLSS antenna …

Buzz Aldrin (LMP)

Okay. Feedwater valve's CLOSED.

Buzz Aldrin (LMP)

And your antenna's …

Neil Armstrong (CDR)

Okay. That's out. … I did my part … Okay.

Bruce McCandless (CAPCOM)

You're cutting out, Neil. You're not readable. I understand you said something about contingency sample container on the ascent engine?

Bruce McCandless (CAPCOM)

We are not reading you, Neil. Buzz, Buzz, this is Houston. Do you read? Over.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. We're reading neither one of you, but standing by.

Bruce McCandless (CAPCOM)

Neil, this is Houston. Neil, this is Houston. Radio check. Over.

Bruce McCandless (CAPCOM)

Buzz, Buzz, this is Houston. Radio check, radio check. Over.

Bruce McCandless (CAPCOM)

This is Houston. I copy a transmission calling Houston; all else was broken up. Over.

Bruce McCandless (CAPCOM)

Neil, this is Houston. If you read, we suggest you unstow one PLSS antenna so we can have communications. Over.

Bruce McCandless (CAPCOM)

Neil, this is Houston. We seem to be reading you now. How do,you read us? Over.

Neil Armstrong (CDR)

Houston, this is Tranquility. How do you read?

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Loud and clear. How us?

Neil Armstrong (CDR)

Loud and clear. We're in the process of switching over to LM COMM here.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. We'd like to verify your steerable antenna in track mode slew. We're going to do a communications handover here on Earth. Over.

Buzz Aldrin (LMP)

Roger. That's affirmative. We're in track mode slew.

Bruce McCandless (CAPCOM)

Roger. Out.

Bruce McCandless (CAPCOM)

Columbia, Columbia, this is Houston. Over.

Michael Collins (CMP)

Roger, Columbia on Charlie. How do you read?

Bruce McCandless (CAPCOM)

Roger, Columbia. This is Houston. Reading you loud and clear on OMNI Charlie. The crew of Tranquility Base is back inside their base, repressurized, and they're in the process of doffing the PLSS's. Everything went beautifully. Over.

Bruce McCandless (CAPCOM)

And we'd like to get P00 and ACCEPT from you. We have a state vector uplink. And, after that, we'd like you to realign your platform to the new REFSMMAT that we sent up a REV or two ago. Over.

Michael Collins (CMP)

Roger. Understand. You want a option 1, P52 option 1.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. We're going to uplink you a new state vector, and then we'll send the REFSMMAT up again, because sending the state vector up will wipe out the one that you have on board; and then you can do a P52 option 1. Over.

Bruce McCandless (CAPCOM)

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

Michael Collins (CMP)

Roger, Houston. Columbia's reading you.

Bruce McCandless (CAPCOM)

Okay, Columbia. We've completed the uplink; the computer is yours. You can go BLOCK; however, we'd like you to hold off on the P52 option 1 align until after you've passed landing site 2; and we're requesting that you perform another P22 and attempt to find the LM this pass. I've got some numbers for you when you're ready to copy. Over.

Bruce McCandless (CAPCOM)

Roger, Columbia. P22 landmark ID is lunar module—make that Tranquility Base; P1, 112 25 08; P2, 112 30 17, 4 nautical miles south. Time of closest approach, 112 31 52; shaft 357. 051, trunnion 047. 432, roll zero, pitch 250, yaw zero. Readback. Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Did you copy my P22 update? Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Did you copy my P22 PAD?

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Do you copy my PAD? Over.

Michael Collins (CMP)

Negative, Bruce. Just give me the latitude and longitude over 2, altitude, and the grid squares. Never mind the other. You're broken up.

Michael Collins (CMP)

Well, that is, if you have new information. Otherwise, I'll just use the old numbers.

Bruce McCandless (CAPCOM)

No, wait a minute. We've got new information.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Can you give us some idea of how you're progressing on the PLSS doffing and preparation for DEPRESS?

Neil Armstrong (CDR)

Roger, Houston. Tranquility Base. We're in the process of using up what film we have, and I'm just getting ready to change the primary ECS canister. Over.

Bruce McCandless (CAPCOM)

Roger, Tranquility. We'd like to hold off as long as possible on the lithium hydroxide canister. Make that one of the last things you do in getting ready for the DEPRESS, if you can. Over.

Neil Armstrong (CDR)

Roger. We're planning on doing that. I was just wondering how much longer we want to wait, though. We've probably got another half an hour's worth of picture taking, and I guess we could run through an eat cycle and then change the canister, and then DEPRESS. Over.

Bruce McCandless (CAPCOM)

Roger. That sounds fine to us.

Neil Armstrong (CDR)

Well, it'll be a little crowded in here for a while.

Michael Collins (CMP)

Houston, Columbia. You got the new coordinates?

Bruce McCandless (CAPCOM)

Columbia. This is Houston. Go ahead.

Michael Collins (CMP)

Roger, Have you got the new coordinates for me?

Bruce McCandless (CAPCOM)

Roger. Latitude 00.691—that would be plus 00.691—and longitude over 2 is plus 11.713. The altitude is minus 1.44 nautical miles. Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. On latitude, make that plus 00.692, rounding off. Over.
