...time, just 2½ hrs. after launch, the spacecraft was cleared by Houston for "translunar insertion" (TLI). Firing for five minutes, the reliable S-4B engine accelerated the ship to 24,245 m.p.h., fast enough to tear it loose from the earth's gravitational embrace and send it toward the moon. At a point 43,495 miles from the moon, lunar gravity exerted a force equal to the gravity of the earth, then some 200,000 miles distant. Beyond that crest, lunar gravity predominated, and Apollo was on the "downhill" leg of its journey...
Continuing their flawless flight, the astronauts zoomed past the western rim of the moon at 5,645 m.p.h. They were whipped behind the far side and into lunar orbit by the moon's gravity and a 5-min. 57-sec. burn of the reliable SPS engine that reduced their speed to 3,736 m.p.h. When they emerged from behind the eastern edge, after 34 minutes during which radio communication was blocked, they had dropped into a 70-by 196-mile-high orbit...
That was about as close as Collins, the affable, relaxed Air Force lieutenant colonel, would get. Before the trip, he complained good-humoredly that because he would be piloting Columbia during the moon walk, he would be "about the only person in the world who won't get to see the thing on television." He asked Houston to save a videotape for him. At least, said Collins, "I'm going...
Coming around the eastern limb of the moon on their first revolution, the astronauts began sending another TV show to earth. This time they focused the camera on the desolate landscape below. After a long period of silence, a Houston capsule communicator pleaded: "Would you care to comment on some of those craters as we go by?" At last the astronauts came to life...
...observation you can make if you have some time up there. There's been some lunar transient events reported in the vicinity of Aristarchus." Astronomers in Bochum, West Germany, had observed a bright glow on the lunar surface?the same sort of eerie luminescence that has intrigued moon watchers for centuries. The report was passed on to Houston and thence to the astronauts. Almost immediately, Armstrong reported back, "Hey, Houston, I'm looking north up to ward Aristarchus now, and there's an area that is considerably more illuminated than the surrounding area. It seems to have a slight amount...
