Little West (lunar crater) maps. The name was officially approved by IAU's Working Group for Planetary System Nomenclature on July 26, 2017 alongside another small crater near the landing site called Double. Little West (lunar crater) Little West is a small crater (30-meter diameter) in Mare Tranquillitatis on the Moon, east of the Apollo 11 landing site known as Tranquility Base. The Apollo 11 astronauts Neil Armstrong and Buzz Aldrin landed the Lunar Module (LM) "Eagle" approximately 60 meters west of Little West Crater on July 20, 1969. This is the crater Neil Armstrong mentions during his final descent onto the lunar surface. The
Apollo Lunar Module Aircraft was awarded the contract two months later. Grumman had begun lunar orbit rendezvous studies in the late 1950s and again in 1961. The contract cost was expected to be around $350 million. There were initially four major subcontractors—Bell Aerosystems (ascent engine), Hamilton Standard (environmental control systems), Marquardt (reaction control system) and TRW's Space Technology Laboratories (descent engine). The Primary Guidance, Navigation and Control System (PGNCS) was developed by the MIT Instrumentation Laboratory; the Apollo Guidance Computer was manufactured by Raytheon (a similar guidance system was used in the command module). A backup navigation tool, the Abort Guidance System (AGS),
