A missed anniversary - Apollo 11
Let this one slip by. Thirty-seven years ago, two American astronauts walked on the surface of the moon.
First landing on moon. Apollo 11 (AS-506) - with astronauts Neil A. Armstrong, Michael Collins, and Edwin E. Aldrin, Jr., aboard - was launched from Pad A, Launch Complex 39, KSC, at 9:32 a.m. EDT July 16. The activities during earth-orbit checkout, translunar injection, CSM transposition and docking, spacecraft ejection, and translunar coast were similar to those of Apollo 10.I vividly remember watching this live on TV with my Mom and Dad. Amazing times and in some senses, an event that has never been duplicated. A real pity that NASA (National Arrows and Spears Administration) got so bureaucratized -- we need to seriously cut their fat and give 10% of their budget to people like Burt Rutan -- we would be back in Space (and reliably!) in a matter of years.

At 4:40 p.m. EDT July 18, the crew began a 96-minute color television transmission of the CSM and LM interiors, CSM exterior, the earth, probe and drogue removal, spacecraft tunnel hatch opening, food preparation, and LM housekeeping. One scheduled and two unscheduled television broadcasts had been made previously by the Apollo 11 crew.
The spacecraft entered lunar orbit at 1:28 p.m. EDT on July 19. During the second lunar orbit a live color telecast of the lunar surface was made. A second service-propulsion-system burn placed the spacecraft in a circularized orbit, after which astronaut Aldrin entered the LM for two hours of housekeeping including a voice and telemetry test and an oxygen-purge-system check.
At 8:50 a.m. July 20, Armstrong and Aldrin reentered the LM and checked out all systems. They performed a maneuver at 1:11 p.m. to separate the LM from the CSM and began the descent to the moon. The LM touched down on the moon at 4:18 p.m. EDT July 20. Armstrong reported to mission control at MSC, "Houston, Tranquillity Base here - the Eagle has landed." (Eagle was the name given to the Apollo 11 LM; the CSM was named Columbia.) Man's first step on the moon was taken by Armstrong at 10:56 p.m. EDT. As he stepped onto the surface of the moon, Armstrong described the feat as "one small step for a man - one giant leap for mankind."
Aldrin joined Armstrong on the surface of the moon at 11:15 p.m. July 20. The astronauts unveiled a plaque mounted on a strut of the LM and read to a worldwide TV audience, "Here men from the planet earth first set foot on the moon July 1969, A.D. We came in peace for all mankind." After raising the American flag and talking to President Nixon by radiotelephone, the two astronauts deployed the lunar surface experiments assigned to the mission and gathered 22 kilograms of samples of lunar soil and rocks. They then reentered the LM and closed the hatch at 1:11 a.m. July 21. All lunar extravehicular activities were televised in black-and-white. Meanwhile, Collins continued orbiting moon alone in CSM Columbia.
