The engine developed about 3,500 pounds-force (16 kN) of thrust, which produced a velocity of 2,000 meters per second from lunar launch, to LOR, and CM docking. [7] [2] It weighed 180 pounds (82 kg), with a length of 47 inches (120 cm) and diameter of 34 inches (86 cm). [8] [unreliable source?] Lunar ascent by Apollo 17 ascent stage.

The Apollo 10 ascent stage engine was fired until its fuel was used up, sending it past the Moon into a heliocentric orbit. [ 9 ] [ 10 ] The Apollo 11 ascent stage was left in lunar orbit to eventually crash; all subsequent ascent stages (except for Apollo 13) were intentionally steered into the Moon to obtain readings from seismometers placed ...
Engineers at Arnold Air Base with an Apollo service module engine Apollo Service Module Propulsion System The service propulsion system ( SPS ) engine was originally designed to lift the CSM off the surface of the Moon in the direct ascent mission mode, [ 20 ] The engine selected was the AJ10-137 , [ 21 ] which used Aerozine 50 as fuel and ...
Complete Apollo spacecraft stack: launch escape system, command module, service module, Lunar Module, and spacecraft–LM adapter The Apollo 17 CSM seen in lunar orbit from the ascent stage of the Lunar Module. The Apollo spacecraft was composed of three parts designed to accomplish the American Apollo program's goal of landing astronauts on ...
NASA currently has a group of flight controllers at the Johnson Space Center in Houston for the International Space Station (ISS). The Space Shuttle flight control team (as well as those for the earlier Gemini, Apollo, and Skylab programs) were also based there.
Television ratings — and now a new poll — clearly illustrate the phenomenon. Election news on CNN and MSNBC was taking up too much of Sam Gude's time before the election, said the 47-year-old ...
Some LESS designs used a single engine under the center, but many used multiple engines around the edge, typically based on the Apollo reaction control system (RCS) thrusters used for attitude control on the command and service module (CSM) and lunar module (LM). These had a thrust of around 100 pounds-force (440 N) each, so putting eight ...
