Apollo Lunar Module. The Apollo Lunar Module (LM / ˈlɛm /), 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 ...
Apollo 10 (May 18–26, 1969) was the fourth human spaceflight in the United States' Apollo program and the second to orbit the Moon. NASA, the mission's operator, described it as a "dress rehearsal" for the first Moon landing (Apollo 11, two months later [ 4 ]). It was designated an "F" mission, intended to test all spacecraft components and ...
Transposition, docking, and extraction (often abbreviated to transposition and docking) was a maneuver performed during Apollo lunar landing missions from 1969 to 1972, to withdraw the Apollo Lunar Module (LM) from its adapter housing which secured it to the Saturn V launch vehicle upper stage and protected it from the aerodynamic stresses of launch.
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. 4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion ...
The Apollo command and service module (CSM) was one of two principal components of the United States Apollo spacecraft, used for the Apollo program, which landed astronauts on the Moon between 1969 and 1972. The CSM functioned as a mother ship, which carried a crew of three astronauts and the second Apollo spacecraft, the Apollo Lunar 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.
Apollo 16 CSM+LM: 52,759 kg (116,314 lb) Heaviest spacecraft sent to lunar orbit. First mission to land in Lunar Highlands.

Apollo 15 was the first of the Apollo program's "J" Missions [ 2] which used an enhanced Lunar Module that was capable of supporting a 3-day stay on the lunar surface *and* the delivery of the Lunar Roving Vehicle (LRV or "Rover") to the surface to allow the crew to extend the range of their exploration and to provide remote TV coverage.
