Apollo 11 re-enactment – We choose the moon – Update

Some news of the Apollo 11 flight to land a man on the moon:

At ground elapsed time (GET) 66:29 hours:

This is Apollo Control, 66 hours 29 minutes Ground Elapsed Time. Apollo 11 presently 22,952 nautical miles out from the moon, and traveling at a velocity of 3858 feet per second. 2 hours 29 minutes remaining in the sleep period. However, as mentioned earlier, this likely will run another 2 hours. Clock counting down to lunar landing, showing 36 hours 16 minutes. Still tracking through the Honeysuckle Creek, Australia tracking station, and all is rather quiet here in the Control Center during the sleep watch. At 66 hours 30 minutes Ground Elapsed Time, this is Apollo Control.

At GET 67:28 hours:

This is Apollo Control 67 hours, 28 minutes ground elapsed time. Midcourse correction burn number 4 has been deleted from the Flight Plan on the recommendation to Flight Director Glynn Lunney from the Flight Dynamics Officer, Jay Green. The maneuver, had it been carried out as planned, would be in the neighborhood of one-half foot per second velocity change. As it is now, the trajectory is being predicted to arrive at near point or closest approach of about 62 nautical miles plus or minus two miles if nothing else is done to the trajectory. That is if no maneuver is made. The spacecraft cabin pressure now holding at 4.7 pounds per square inch. Temperature 60 degrees F. The planned sleep period has another hour and one-half to go but as mentioned earlier it will likely run another couple hours in as much as midcourse correction burn number 4 will not be made and the crew will not have to spend the time preparing to do the burn, align the platform and do all the chores necessary for doing a maneuver of this sort. Clock counting down to lunar landing showing 35 hours, 17 minutes. And at 67 hours, 29 minutes ground elapsed time, this is Apollo Control.

At GET 68:29 hours:

This is Apollo control 68 hours, 28 minutes ground elapsed time. Some 2 hours and 31 minutes remaining crew sleep period according to the revised schedule inasmuch as midcourse correction burn number 4 has been omitted. Still being tracked – Apollo 11 is still being tracked by the Honeysuckle Creek, Australia station. And, here in mission yesterday’s hour and a half long television pass as the crew manned the LM for the first time in checkout is being replayed. This will be piped across to the news center for anyone who might want to view it again. At 68 hours, 29 minutes ground elapsed time, this is Apollo control.
