Surveyor 1 was the first lunar soft-lander in the unmanned Surveyor program of the National Aeronautics and Space Administration (NASA, United States).
This lunar soft-lander gathered data about the lunar surface that would be needed for the manned Apollo Moon landings that began in 1969. The successful soft landing of Surveyor 1 on the Ocean of Storms was the first one by an American space probe onto any extraterrestrial body, and it occurred just four months after the first Moon landing by the Soviet Union’s Luna 9 probe. This was also a success on NASA’s first attempt at a soft landing on any astronomical object.
Surveyor 1 was launched May 30, 1966, from the Cape Canaveral Air Force Station at Cape Canaveral, Florida, and it landed on the Moon on June 2, 1966. Surveyor 1 transmitted 11,237 still photos of the lunar surface to the Earth by using a television camera and a sophisticated radio-telemetry system.
The Surveyor program was managed by the Jet Propulsion Laboratory, in Los Angeles County, but the entire Surveyor space probe was designed and built by the Hughes Aircraft Company in El Segundo, California.
