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.
- Bruce McCandless (CAPCOM)
-
Tranquility Base, this is Houston. Loud and clear. How us?

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.
- 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.
- 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)
-
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.

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

-
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.

-
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. 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.
