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 ...
When NASA awarded the initial Apollo contract to North American Aviation on November 28, 1961, it was still assumed the lunar landing would be achieved by direct ascent rather than by lunar orbit rendezvous. [4] Therefore, design proceeded without a means of docking the command module to a lunar excursion module (LEM). But the change to lunar ...
Apollo 14 (January 31 – February 9, 1971) was the eighth crewed mission in the United States Apollo program, the third to land on the Moon, and the first to land in the lunar highlands. It was the last of the " H missions ", landings at specific sites of scientific interest on the Moon for two-day stays with two lunar extravehicular ...
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 Bell Aerosystems Lunar Landing Research Vehicle (LLRV, nicknamed the Flying Bedstead) [1] was a Project Apollo era program to build a simulator for the Moon landings.The LLRVs were used by the FRC, now known as the NASA Armstrong Flight Research Center, at Edwards Air Force Base, California, to study and analyze piloting techniques needed to fly and land the Apollo Lunar Module in the Moon ...

The Apollo primary guidance, navigation, and control system (PGNCS, pronounced pings) was a self-contained inertial guidance system that allowed Apollo spacecraft to carry out their missions when communications with Earth were interrupted, either as ...
The Apollo Lunar Roving Vehicle is a battery electric vehicle designed to operate in the low-gravity vacuum of the Moon and to be capable of traversing the lunar surface, allowing the Apollo astronauts to extend the range of their surface extravehicular activities.
In terms of photography, Apollo 14's crew proved to be less "trigger-happy" than the preceding Apollo 12 crew and only took 417 pictures on the Moon, compared to 583 on the earlier mission. However, 288 of these were components of 17 distinct panoramas and ALSJ lists another 25 sub-panoramas within these.
