Spacelog Apollo 11

Houston. ***

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

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

Okay *** read?

A, receive. B, off.

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

ICS, push to talk.

Houston, this is Tranquility. How do you read?

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

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

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.

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

Columbia, Columbia, this is Houston. Over.

Roger, Columbia on Charlie. How do you read?

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.

Hallelujah.

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.

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

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.

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

Roger, Houston. Columbia's reading you.

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.

Roger. Stand by.

Ready to copy.

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.

Houston, Columbia.

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

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

Kilo 0.9 and 6.3. Thank you. One of these grid squares is about as much as you can scan on a single pass.

Roger.

And for your information, Columbia, you're approaching the VHF line of site COMM limit with Tranquility Base. LOS will be at 38 minutes plus 25 seconds. Over.

Roger.

Roger. And we've had to disable the one way MSFN relay owing to a ground site reconfiguration down here. Over.

Houston, Columbia. …

This is Houston. Go ahead. Over.

Roger. I can't see them.

Roger. I guess that takes care of the news for today, Mike.

All right. Roger.

You might be interested in knowing, Mike, that we have gotten reflections back from the laser reflector ray they deployed, and we may be able to get some information out of that a little later.

Roger. I need a very precise position, because I can only do a decent job of scanning maybe one of those grid squares at a time. The area that we've been sweeping covers 10's and 20's and 30's of them.

Roger. We understand. This is intended to be your last P22. We don't want to use up too much fuel in this effort. Over.

Roger. How's the fuel coming?

Roger. There's no problem fuel wise. It's just that there seems to be a limit to the number of P22's and the number of grid squares you can search over.

Roger. Well, I'll continue this maneuver then to roll 82, pitch 218, yaw zero, if that's okay with you, and do a P52 in that attitude. And that'll be a sleep …

Roger. That's fine with us. And P52 in that attitude.

Tranquility Base, this is Houston. Over.

Houston, Tranquility Base. Go ahead.

Roger. When you all have a free moment, I have your T8 through T12 block data. Over.

Roger. Stand by one.

Houston, Tranquility Base. Ready to copy.

Roger, Tranquility. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Readback. Over.

Roger. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Over.

Readback correct. Houston out.

Houston. Columbia.

Houston, Columbia on high gain.

Houston, Tranquility Base.

Columbia. Columbia, this is Houston. Over.

Columbia in the high gain.

Roger. Reading you loud and clear on the high gain, Columbia.

Roger. Going to P52 attitude. You want a crew status report?

Say again, Columbia?

I say again, I am maneuvering to the P52 attitude, and do you want a crew status report?

Roger. And go ahead with your crew status report.

Roger. No medication. Radiation 100.16.

Houston. We copy.

Houston, Tranquility Base.

Go ahead, Tranquility.

Roger. The weight of the RCU was 12 ounces. That was by itself without the bag, and the weight of the water from the CDR's PLSS was 12 1/2 ounces. That's reading zero with the bag on.

This is Houston. We copy. And, for your information, the new LM weight after jettison of equipment including lithium hydroxide canister is 10837. Over.

Houston, Columbia. Did you copy the P52?

Columbia, this is Houston. Affirmative.
