The Apollo Lunar Module (LM / ˈ l ɛ m /), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
During this time Kelly helped develop the lunar orbit rendezvous concept. In late 1962, Grumman won the $2-billion government contract from NASA. Kelly was promoted to lead the design team for the Lunar Excursion Module (LEM). He was in charge of more than 7,000 employees in design and building the Lunar Module.
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 .
LK (left) and Apollo Lunar Module (right). A lunar module is a lunar lander designed to allow astronauts to travel between a spacecraft in lunar orbit and the lunar surface. As of 2021, the Apollo Lunar Module is the only lunar module to have ever been used in human spaceflight, completing six lunar landings from 1969 to 1972 during the United States' Apollo program.
In November 1964, two-rocket models were put on indefinite hold, but Bendix and Boeing were given study contracts for small rovers. The name of the lunar excursion module was changed to simply the lunar module, indicating that the capability for powered "excursions" away from a lunar-lander base did not yet exist. There could be no mobile lab ...
Apollo 13 was slated to be the third landing on the moon after Apollo 8 (1968) and Apollo 12 (1969). Launched on April 11, 1970, the crew was led by commander Lovell, along with command module ...
The propulsion system for the descent stage of the lunar module was designed to transfer the vehicle, containing two crewmen, from a 60-nautical-mile (110 km) circular lunar parking orbit to an elliptical descent orbit with a pericynthion of 50,000 feet (15,000 m), then provide a powered descent to the lunar surface, with hover time above the lunar surface to select the exact landing site.
On May 12, 1966, NASA announced the vehicle would be called the "uprated Saturn I", at the same time the "lunar excursion module" was renamed the lunar module. However, the "uprated Saturn I" terminology was reverted to Saturn IB on December 2, 1967. [2]
