Apollo Lunar Module

Apollo Lunar Module - - National Air and Space Museum

The Apollo Lunar Module was the landing portion of the Apollo spacecraft built for the Apollo program. Designed to carry a crew of two from lunar orbit to the surface and then back to the Command Module. It consisted of an ascent stage and descent stage and was ferried to lunar orbit by its companion Command Module.

After completing its mission, the Lunar Module was discarded into space. The Lunar Module was the first manned spacecraft crewed vehicle to land on the Moon.

Six such craft successfully landed on the Moon between 1969 and 1972. A seventh provided propulsion and life support for the crew of Apollo 13 when their Command Module was disabled by an oxygen tank explosion on route to the Moon. The total cost of the Lunar Module for the development and the units produced was over $2.2B.

On display at the museum is LM-2, which was intended for the second unmanned flight, but instead was used for ground testing. Landing gear was added for drop testing. It does not have optical alignment telescope and flight computer.
