S69-39011 (July 1969) — TRW Incorporated’s artist concept depicting the Apollo 11 Lunar Module (LM) descending to the surface of the moon. Inside the LM will be astronauts Neil A. Armstrong, commander, and Edwin E. Aldrin Jr., lunar module pilot. Astronaut Michael Collins, command module pilot, will remain with the Command and Service Modules (CSM) in lunar orbit. TRW’s LM descent engine will brake Apollo 11’s descent to the lunar surface. The throttle-able rocket engine will be fired continuously the last 10 miles of the journey to the moon, slowing the LM to a speed of two miles per hour at touchdown. TRW Incorporated designed and built the unique engine at Redondo Beach, California under subcontract to the Grumman Aircraft Engineering Corporation, Bethpage, New York, the LM prime contractor.

S69-33765 (12 May 1969) — Artist’s concept depicting the firing of the Apollo 10 Lunar Module descent engine for 42 seconds to propel “Snoopy” back into a higher lunar orbit for rendezvous and docking with the Command and Service Modules. Earlier, the LM descent engine will be fired for 27 seconds to take astronauts Thomas P. Stafford, Apollo 10 commander; and Eugene A. Cernan, lunar module pilot, to within 10 miles of the moon’s surface. Astronauts John W. Young, command module pilot, will remain in the Command Module, “Charlie Brown,” in lunar orbit. Developed by TRW’s Systems Group at Redondo Beach, California, under Grumman subcontract, the throttleable descent engine will be used to soft land the LM on the lunar surface during Apollo 11 and subsequent Apollo missions.
