Roger, 11. The problem on that initially—starting up the PTC was we failed to do the VERB 49 which—and load the desired initial attitude; so the DAP tried to take it back to the old attitude that we had started up in number of hours to go. That's why we picked up the rates in the other axes. We're going to wait in this attitude for about 20 minutes to dump out the rates again, and than we'll proceed with the VERB 49 and load our attitude that we have at the time—at this time. Over.

Okay. That sounds good, Charlie. When you get to the VERB 49, I'd like for you to give me the three gimbal angles that you want loaded.

All right, Buzz. It's—flyby is the purpose. SPS/G&N: 62815, plus 097, minus 020 070 54 5944, minus 00028, plus 00023, plus 00069 029 149 312, apogee is NA, plus 00221 00078 001 00034, sextant star 01 2385 227, boresight star is NA NA NA. Latitude is minus 0265, minus 16500, 11899 36228, 144 56 47. In the comments: your set stars are Deneb and Vega, 007 144 068. No ullage. It's a docked burn using the PTC REFSMMAT. Stand by for your readback. 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.

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

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.
-
Michael Collins (CMP)
-
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.

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.
-
Michael Collins (CMP)

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

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.

Michael Collins (CMP)
-
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.
-
Charlie Duke (CAPCOM)
-
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.

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.
-
Michael Collins (CMP)
-
Okay, I'll try it with the telescope; and if I don't see it there, then I'll try the sextant.

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

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