Kelley, who served as the engineering manager and eventually deputy program manager for the lunar module program, has recalled in the past, "We didn't know anything about space anymore than most people did at that time.
But we did know a lot about producing reliable flying machines. Thirteen lunar modules were built and six landed on the moon. The last Apollo flight took place in December , with Apollo The Lunar Module is one of three components making up the Apollo spacecraft. The Saturn V rockets that launched the Apollo crafts were designated in , at space centers in Alabama, Florida, and Texas.
Situated in the Cradle of Aviation setting that replicates the Eagle's moon landing, the LM is one of three surviving earth-bound lunar modules. ASME Membership 1 year has been added to your cart. The artifacts in this exhibition indicate the unprecedented ingenuity and planning required for a trip through space to another world. For 28 hours he served as a communications link and photographed the lunar surface. After reclaiming Armstrong and Aldrin from the ascent stage of the Lunar Module, Columbia was the only part of the spacecraft to return to Earth.
During the mission, astronauts Armstrong and Aldrin became the first human explorers of another world. During the journey to and from the Moon, Columbia—its interior space about as roomy as a large automobile—served as main quarters for the astronauts, a place for working and living. The blunt-end design for the Command Module was chosen to build upon experience gained with the similarly shaped Mercury and Gemini spacecraft.
The spacecraft reentered the atmosphere with its protective heat shield the widest end of the spacecraft facing forward. Layers of special "ablative" material on the shield were purposely allowed to burn away during reentry to help dissipate the extremely high temperatures caused by atmospheric friction.
Command Module Specifications Height: 3. The Apollo 11 astronauts carried these tools to make minor repairs to their spacecraft. This kit was aboard the Apollo 11 command module during its lunar mission, July , The Service Module contained oxygen, water, and electric power for the command module.
The Service Module also housed the service propulsion system—the rocket engine that put the spacecraft into lunar orbit and later boosted it back toward Earth. This module was jettisoned just before reentry into the Earth's atmosphere. After three days of travel through space, the astronauts and the three Apollo spacecraft—command module Columbia, the Service Module, and the Lunar Module Eagle—entered orbit around the Moon on July During the flight to the Moon astronaut Michael Collins had repositioned the Lunar Module so that Columbia and Eagle were joined at their respective hatches.
Over the next day the astronauts readied the Lunar Module and themselves for the descent to the Moon. The Lunar Module LM was used for descent to the lunar surface and served as a base while the astronauts were on the Moon.
A separate ascent stage, comprising the top portion of the Lunar Module, lifted the astronauts from the Moon's surface to rendezvous and dock with the command module, orbiting the Moon. Because lunar modules were designed to fly only in the vacuum of space, they did not have to be streamlined like an aircraft or carry a heat shield for protection during reentry. Once a lunar module was launched into space, it could not return to Earth. To learn more about the Lunar Module transposition and docking, as well as descending to the lunar surface, visit the page At the Moon.
In the meantime, it will undergo conservation. The Apollo Lunar Module LM was a two-stage vehicle designed by Grumman to ferry two astronauts from lunar orbit to the lunar surface and back. The upper ascent stage consisted of a pressurized crew compartment, equipment areas, and an ascent rocket engine. The lower descent stage had the landing gear and contained the descent rocket engine and lunar surface experiments.
Because the test flight of LM 1, performed as part of the Apollo 5 mission, was so successful, a second unmanned LM test mission was deemed unnecessary. LM-2 was used for ground testing prior to the first successful Moon-landing mission. When it returned to the United States, it was reunited with its descent stage, modified to appear like the Apollo 11 Lunar Module "Eagle," and transferred to the Smithsonian for display.
Between and , six lunar modules identical to this one landed a total of 12 American astronauts on the Moon. This lunar module, LM-2, never flew in space.
