Spacelog Apollo 11

Roger. Big Bubba's watching.

And we're glad of it.

Boy, you guys have sure been doing a good job of watching us, Charlie. We appreciate it.

The spacecraft's been beautiful, 11. We've really no complaints at all. Looks—Things are really great.

Can you see this DSKY on the MDC?

That's affirmative. It appears that—can't quite tell what program … went P00. We see you punching in a VERB 35, I think it is. Over.

Yes. Might as well tell the EECOMM's—or tell the GNC and everybody to hold on to their hat and I'll push the EKTER button.

Roger.

Roger. We see a real display now.

That's a good demonstration of how the crew has the interface with the computer, talking to the programs and all that we have in the computer.

Well, that's right, Charlie. Sometimes it tells us things and sometimes we tell it things and mostly it talks to us.

11, Houston, We just lost our pic—I see we're going back outside now. Over.

…

11, Houston. We copy. Over.

Roger. We copy, and as we pan back out to the distance at which we see the Earth, well, it's Apollo 11 signing off.

Roger, Apollo 11. Thank you much for the show. It's a real good half hour. Appreciate it. Thank you very much. Out.

Okay. That's it, Charlie.

11, Houston. We appreciate the show. Thank you very much. Over.

Right.

Apollo 11, Houston. Would you key ERROR RESET on the DSKY, please? Over.

Okay. We should be straightened out now, Charlie, and back in P00.

Houston, Apollo 11. How do we stand on this O₂ fuel cell purge? You want to go ahead and do that as scheduled in the flight plan?

Stand by, 11. Over.

Okay.

11, Houston. You can commence the O₂ fuel cell purge now if you'd like. Over.

Okay. Fine.

While Buzz is doing that, I'll change the lithium hydroxide.

Hello, Apollo 11, Houston. Over.

Go ahead, Houston. Apollo 11.

Roger, Buzz. The attitude that we're in right now is a convenient one to start PTC in. We'd be satisfied with this attitude. So we'd like you to disable quads Charlie and Delta; and we'll wait about 5 to 10 minutes, and than we'll establish the PTC. Over.

Roger. Disable Charlie and Delta, and we'll wait before starting PTC.

Hello, Apollo 11, Houston. The rates are damped out well enough for you to initiate the PTC now. Over.

Houston, Apollo 11.

Roger. Go ahead.

Roger. This time the DAP didn't like 0.3. It's—We followed the procedures; we got down to 70 000 ENTER. It took off at about 0.7.

Roger. We're copying that. Stand by.

Houston, Apollo 11. Would you like high gain back?

Roger. And you—Would you select ATTITUDE HOLD? Over.

Houston. Would you say again what your request is?

Roger, 11. We'd like you to go back to ATTITUDE HOLD. Over.

Roger.

11, Houston. Looks like we're going to have to reinitialate—reinitialize this PTC.

All right.

Okay. Do you have any roll angle that you'd like to stop it in, Charlie? I haven't stopped it yet.

Stand by.

11, Houston. It's your preference. Right now if you want to. Over.

That's affirmative. Over.

Okay. Ready to copy.

Okay. Would you give me GET of O.05g again, please?

Roger. 144 56 47. Over.

Roger. Flyby SPS/G&N: 62815, plus 097, minus 020 070 54 5944, minus 00028, plus 00023, plus 00069, 269 149 312 NA, plus 00221 00078 001 00034, 01 2185 227 NA, minus 0265, minus 16500 11899 36228 144 56 47, Deneb and Vega, 007 144 068. No ullage; docked, PTC REFSMMAT. Over.

Roger. Say again your roll angle, Buzz. I copy—I read 029. Over.

Roger. 029.

Roger. Good readback.

Houston, Apollo 11. On the 0.7 rate, the rate loaded into the DAP is 0.1 or 0.2.

Hello, Apollo 11. Houston. Over.

Houston, Apollo 11. Go.

Roger, Mike. Would you please copy down your VERB 16 NOUN 20 ICDU angles now, then execute a VERB 49 and load that—those angles, the NOUN 20 that you see on the DSKY into the VERB—into the NOUN 22 slot; and PRO on that, and that will start our 20-minute rate period. Over.

Okay, Charlie. I'll do that right now in just a matter of inches. Those numbers are plus 04511, plus 09021, and plus 35984. Over.

Roger.

Houston, Apollo 11. I've done that and, of course, I got an immediate 50 18. So I guess we're set up to proceed from here, and I'll start the 20-minute timer.

That's affirmative.

Houston. I still question that 0.7 rate with 0.2 loaded into the DAP, though. Could you explain that one?

Roger. We're working on it.

Apollo 11, Houston. Over.

Houston, Apollo 11.

Roger. We got a little laser visual experiment we'd like to—for you to do for us. If—if you got the Earth through any of your windows or through the telescope, would you so advise? Over.

Stand by one, Charlie.

At this roll attitude, what should our highgain angles be? Maybe that would help us locate you. We don't see you in the lens.

Stand by.

Hello, Apollo 11. Houston. Those high gain angles are pitch minus 70, yaw 90. We think the Earth is apparently pretty close to plus z-axis. Over.

Okay.

Okay, Charlie. I got you in the telescope.

Roger, Apollo 11. We've got a laser that we're going to—It's a blue-green laser that we're going to flash on and off at a frequency of on for a second, off for a second. It's coming out of McDonald Observatory near El Paso, which is—should be right on the terminator—or right inside the terminator. We are going to activate that momentarily. Would you please take a look through the telescope and see if you can see it. Over.

Telescope? Or sextant?

Either one. Over.

Okay, I'll try it with the telescope; and if I don't see it there, then I'll try the sextant.

Roger. We'll give you the word when they've got it turned on. Over.

Okay.

11, Houston. They don't have it turned on yet. We'll give you the word when they got it turned on. Over.

Okay.

Hello, Apollo 11. Houston. We noticed the CRYO pressure dropped a moment ago. Did you stir up the CRYO's? Over.

Roger. We've finished our cycling operations.
