Apollo 11 Spaceflight, First Manned Moon Landing

After more than 2½ hours on the lunar surface, they had left behind scientific instruments that included a retroreflector array used for the Lunar Laser Ranging Experiment and a Passive Seismic Experiment used to measure Moon quakes. They also left an American flag, an Apollo 1 mission patch, and a plaque (mounted on the LM Descent Stage ladder) bearing two drawings of Earth (of the Western and Eastern Hemispheres), an inscription, and signatures of the astronauts and President Richard M. Nixon. The inscription read:
Here Men From The Planet Earth First Set Foot Upon the Moon, July 1969 A.D. We Came in Peace For All Mankind.
They also left behind a memorial bag containing a gold replica of an olive branch as a traditional symbol of peace and a silicon message disk. The disk carries the goodwill statements by Presidents Eisenhower, Kennedy, Johnson and Nixon and messages from leaders of 73 countries around the world. The disc also carries a listing of the leadership of the US Congress, a listing of members of the four committees of the House and Senate responsible for the NASA legislation, and the names of NASA's past and present top management. (In his 1989 book, Men from Earth, Aldrin says that the items included Soviet medals commemorating Cosmonauts Vladimir Komarov and Yuri Gagarin.) Also, according to Deke Slayton's book Moonshot, Armstrong carried with him a special diamond-studded astronaut pin from Slayton.
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.
