The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N 2 O 4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion ...
The ascent stage contained the crew cabin with instrument panels and flight controls. It contained its own ascent propulsion system (APS) engine and two hypergolic propellant tanks for return to lunar orbit and rendezvous with the Apollo command and service module.
At 17:54:00 UTC, they lifted off in Eagle 's ascent stage to rejoin Michael Collins aboard Columbia in lunar orbit. After the crew re-boarded Columbia, the Eagle was abandoned in lunar orbit. The location of its impact on the Moon's surface during an orbit decay is unknown, and there is evidence that Eagle may still be in orbit. [3] [4]
Booster systems engineer The booster systems engineer monitored and evaluated performance of propulsion-related aspects of the launch vehicle during prelaunch and ascent. During the Apollo program there were three booster positions, who worked only until trans-lunar injection (TLI) was complete; after that, their consoles were vacated. Booster ...
It supplied life support systems for two astronauts for up to four to five days on the Apollo 15, 16 and 17 missions. The spacecraft was designed and manufactured by the Grumman Aircraft Company. The descent stage contained the landing gear, landing radar antenna, descent propulsion system, and fuel to land on the Moon
All told, Perseverance's ascent covered 1,640 vertical feet and required navigating treacherous 20-degree slopes, NASA's Jet Propulsion Laboratory said in a press release last week. The rover then ...
The 2005 NASA Exploration Systems Architecture Study (ESAS), part of the 2004 Vision for Space Exploration, recommended that the crew exploration vehicle (CEV) lunar surface access module (LSAM) ascent stage propulsion and service module propulsion systems employ a pressure-fed LOX/liquid methane (CH 4) engine.
