    Descent propulsion system. 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 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. 4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion ...

    The camera was stowed in the LM, and it used the LM's communications systems to evaluate their performance before lunar operations began. This meant that the CM did not carry a video camera for this mission. It was next used on Apollo 11, carried in the LM's descent stage, in the quad 4 Modularized Equipment Stowage Assembly (MESA).
