The descent propulsion system (DPS - pronounced 'dips') or lunar module descent engine (LMDE), internal designation VTR-10, is a variable-throttle hypergolic rocket engine invented by Gerard W. Elverum Jr. [3] [4] [5] and developed by Space Technology Laboratories (TRW) for use in the Apollo Lunar Module descent stage.
The Apollo LM Truck (also known as Lunar Payload Module) was a stand-alone LM descent stage intended to deliver up to 11,000 pounds (5.0 t) of payload to the Moon for an uncrewed landing. [66] This technique was intended to deliver equipment and supplies to a permanent crewed lunar base .
Chandrayaan-2 image of the Lunar Module Eagle descent stage at Tranquility Base. In April 2021 the ISRO Chandrayaan-2 orbiter captured an image of the Apollo 11 Lunar Module Eagle descent stage. The orbiter's image of Tranquility Base, the Apollo 11 landing site, was released to the public in a presentation on September 3, 2021. [5]
Powered Descent Initiation (PDI) is a term used during the Apollo program Moon landing missions to describe the maneuver of the Apollo Lunar Module as it descended from lunar orbit to a rocket-powered landing. [1] "Eagle was GO to ignite its descent engine, and Armstrong and Aldrin locked their eyes to the glowing numbers displayed before them ...
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 ...

Apollo Lunar Module. The Apollo Lunar Module was a separate vehicle designed to land on the Moon and return to lunar orbit, and was the first true "spaceship" since it flew solely in the vacuum of space. It consisted of a descent stage and an ascent stage. It supplied life support systems for two astronauts for up to four to five days on the ...
