Apollo 11 spaceflight, first manned moon landing

Apollo 11 Spaceflight, First Manned Moon Landing

Film taken from the LM Ascent Stage upon liftoff from the Moon reveals the American flag, planted some 25 feet (8 m) from the descent stage, whipping violently in the exhaust of the ascent stage engine. Buzz Aldrin witnessed it topple: "The ascent stage of the LM separated ...I was concentrating on the computers, and Neil was studying the attitude indicator, but I looked up long enough to see the flag fall over." Subsequent Apollo missions usually planted the American flags at least 100 feet (30 m) from the LM to prevent its being blown over by the ascent engine exhaust.
After rendezvous with Columbia, Eagle's ascent stage was jettisoned into lunar orbit on July 21, 1969 at 23:41 UTC. Just before the Apollo 12 flight, it was noted that Eagle was still likely to be orbiting the Moon. Later NASA reports mentioned that Eagle's orbit had decayed, resulting in it impacting in an "uncertain location" on the lunar surface. The location is uncertain because the Eagle ascent stage was not tracked after it was jettisoned, and the lunar gravity field is sufficiently non-uniform to make the orbit of the spacecraft unpredictable after a short time. NASA estimated that the orbit had decayed within months and would have impacted on the Moon.
On July 23, the last night before splashdown, the three astronauts made a television broadcast in which Collins commented,
"... The Saturn V rocket which put us in orbit is an incredibly complicated piece of machinery, every piece of which worked flawlessly ... We have always had confidence that this equipment will work properly. All this is possible only through the blood, sweat, and tears of a number of a people ...All you see is the three of us, but beneath the surface are thousands and thousands of others, and to all of those, I would like to say, 'Thank you very much.'"
