Aldrin: “Houston, Apollo 11. We’ve got the continent of Africa right facing toward us right now, and of course, everything’s getting smaller and smaller as time goes on. The Mediterranean is completely clear. The Sun looks like it’s about to set around Madagascar. The equatorial belt of Africa stands out quite clearly. We’re seeing a dark green or a muddy colored green, compared to the sandier colors of the southern tip of Africa and, of course, the Sahara northern coast of Africa. There’s a rather remarkable cloud that appears in the vicinity of the border between Afghanistan and Pakistan. It’s just about to go into the sunset now. It is casting quite a large shadow. It’s isolated. There don’t seem to be any other clouds. The band of clouds near the tropical convergent clouds down around the equator clearly separate the clockwise and the counter-clockwise cloud formations. Over.”
This was the final day of preparations for the lunar landing scheduled for the following day. The spacecraft approached the moon, and went behind it, putting Apollo 11 in a blackout with Earth. The crew used that time to prepare for their first lunar orbit insertion maneuver: To position themselves to orbit the moon.
