The Apollo Guidance Computer (AGC) was a digital computer produced for the Apollo program that was installed on board each Apollo command module (CM) and Apollo Lunar Module (LM). The AGC provided computation and electronic interfaces for guidance, navigation, and control of the spacecraft. [ 3 ]
The Apollo 1 spacecraft weighed approximately 45,000 pounds (20,000 kg), while the Block II Apollo 7 weighed 36,400 lb (16,500 kg). (These two Earth orbital craft were lighter than the craft which later went to the Moon, as they carried propellant in only one set of tanks, and did not carry the high-gain S-band antenna.)
APOLLO shooting a laser at the Moon. The laser pulse is reflected from the retroreflectors on the Moon (see below) and returned to the telescope. The round-trip time tells the distance to the Moon to great accuracy. In this picture the Moon is very over-exposed, needed to make the laser beam visible. Apollo 15 Lunar Ranging Retro-Reflector (LRRR).
The Apollo 11 LRRR was deployed on the lunar surface by the Apollo 11 astronaut, Buzz Aldrin, on July 21, 1969. The package was deployed approximately 60 feet (18 m) from Lunar Module Eagle . [ 5 ] Aldrin initially aligned the face of the array in an approximate fashion so that it faced the Earth, with more precise alignment provided by a ...
NASA management was concerned about losing the 400,000 workers involved in Apollo after landing on the Moon in 1969. [3] Wernher von Braun, head of NASA's Marshall Space Flight Center during the 1960s, advocated for a smaller space station (after his large one was not built) to provide his employees with work beyond developing the Saturn rockets, which would be completed relatively early ...
The John F. Kennedy Presidential Library and Museum set up an Adobe Flash website that rebroadcasts the transmissions of Apollo 11 from launch to landing on the Moon. [269] On July 20, 2009, Armstrong, Aldrin, and Collins met with President Barack Obama at the White House. [270] "We expect that there is, as we speak, another generation of kids ...
The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N
Lunar Module Eagle (LM-5) is the spacecraft that served as the crewed lunar lander of Apollo 11, which was the first mission to land humans on the Moon. It was named after the bald eagle , which was featured prominently on the mission insignia .
