The Lunar Module ascent stage was left in lunar orbit. The total time in Lunar Orbit for the Command Module was 59.5 hours with 30 orbits. There was less than 30 seconds of fuel remaining when the Lunar Module took off. Using the descent stage of the LM as a launching platform, the ascent stage of the Lunar Module lifted off from the moon’s surface at 1:54pm on July 21 to rendezvous and dock with the Command Service Module. The two drawings of Earth were of the Western and Eastern Hemispheres. The plaque was made of stainless steel. The plaque was affixed to leg of the Lunar Module and it was signed by US President Richard Nixon, Neil Armstrong, Michael Collins and Edwin ‘Buzz’ Aldrin. The inscription read: Here Men From Planet Earth First Set Foot Upon the Moon July 1969 A.D. The astronauts left behind scientific instruments such as a retro reflector array used for the Lunar Laser Ranging Experiment, an American Flag and other mementos, including a plaque. They collected 21 kg (46 lb) of moon rocks and soil. Neil Armstrong and Buzz Aldrin deployed various instruments and the American Flag. The Lunar Module spent 21 hours 36 minutes on the lunar surface and the crew spent 2 hours 31 minutes outside the Lunar Module. Neil Armstrong said, “One small step for man, one giant leap for mankind”. Neil Armstrong made the first human footprint on the moon. Six hours after landing, Neil Armstrong stepped off the Eagle Lunar Module onto the surface of the Moon at 10:56pm EDT on July 20. You’ve got a bunch of guys about to turn blue. On landing the Eagle announced: “ Houston, Tranquility Base here. The Apollo 11 landing site was Sea of Tranquility. The Eagle landed on the Moon on at 4:17pm EDT on July 20, 1969 with less than 30 seconds worth of fuel left in the lunar module.

Armstrong took manual control of the lunar module at that point and guided it to a landing. The astronauts noticed that the intended landing site was rockier than surveillance photographs had indicated. This was the third flight of the lunar module in the Apollo program.ĭuring the descent to the lunar surface at 6000 feet, a yellow caution light came on in the Lunar Module and the astronauts encountered serious problem which might have caused them to abort. After a careful visual inspection, Eagle fired its engine and began its descent. Astronaut Michael Collins remained aboard the Columbia Command Module and orbited the Moon during the first lunar landing. On July 20, 1969, Neil Armstrong and Edwin ‘Buzz’ Aldrin descended in the Lunar Module Eagle and landed in the Sea of Tranquility and became the first humans to walk on the moon. The CSM-LM separated at 2:11pm on July 20. The spacecraft went into lunar orbit insertion at 1:21pm on July 19. The Command Service Module and the Lunar Module (CSM-LM) docked at 12:56pm. The Translunar injection was at 12:16pm EDT.
The Lunar Module weighted 16,448 kg, of which ascent stage was 4985 kg and the descent stage 11,463 kg. The Command Service Module weighed 30,320 kg (CM was 5960 kg, Service Module: 24,360 kg). The launch weight of the Saturn V was 2,923,387 kg and the total spacecraft weight was 46,678 kg. The Command Module was called Columbia and the Apollo Lunar Module was called Eagle.
The astronauts blasted off on a Saturn V rocket at at 9.32am EDT on July 16, 1969. Neil Armstrong was chosen as the Commander and Edwin ‘Buzz’ Aldrin was the Lunar Module Pilot and Michael Collins was the Command Module Pilot. 29 astronauts trained for the Apollo missions to the Moon. The crew for Apollo 11 was announced in January 1969.
– Fred Haise (Backup Lunar Module Pilot) and – Michael Collins (Command Module Pilot). – Edwin ‘Buzz’ Aldrin (Lunar Module Pilot) and It was the fifth manned mission in the Apollo Program. It was launched on a Saturn V rocket at at 9.32am local time (EDT) on Jfrom Pad 39-A from Kennedy Space Center, Florida, USA. Apollo 11 was the first mission to land a man on the moon.
