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 ...
A major portion of the service module was taken up by propellant and the main rocket engine. Capable of multiple restarts, this engine placed the Apollo spacecraft into and out of lunar orbit, and was used for mid-course corrections between the Earth and the Moon. The service module remained attached to the command module throughout the mission.
Command module disassembled as part of Apollo 1 investigation. Service module (SM-014) used on Apollo 6 mission. Command module (CM-014) later modified and used for ground testing (as CM-014A). [33] Scrapped May 1977. [32] CSM-017 CM-017 flew on Apollo 4 with SM-020 after SM-017 was destroyed in a propellant tank explosion during ground testing ...
Diagram of LOR. Lunar orbit rendezvous (LOR) is a process for landing humans on the Moon and returning them to Earth. It was utilized for the Apollo program missions in the 1960s and 1970s. In a LOR mission, a main spacecraft and a lunar lander travel to lunar orbit. The lunar lander then independently descends to the surface of the Moon, while ...
The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, the only part that returned to Earth; a service module (SM), which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module (LM) that had two stages—a descent stage for landing on the Moon and an ...
The Apollo 17 lunar lander module left behind by US astronauts on the moon’s surface could be causing moonquakes, ... Marusiak was keen about India’s lunar lander mission, Chandrayaan-3, which ...
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 .
The information is used to study Lunar recession due to tidal dissipation and the irregular motion of the Earth. The LRRRs are the only experiments still in use today. The above diagram shows the Apollo 11 version. Apollo 14's was similar to Apollo 11's. The lower diagram shows the larger Apollo 15 version. Lunar Atmosphere Composition ...
