The Ranger program was designed to take precise photographs of the Moon and gather information on the composition of the lunar surface. Nine Ranger probes were launched aboard an Atlas-Agena B rocket between August 23, 1961, and March 24, 1965. They were produced by JPL, the Jet Propulsion Laboratory (California). After several failures with Ranger 1 through Ranger 6, the program became a success starting with Ranger 7. All photos are vintage black-and-white silver gelatin prints, measuring 20.5 x 25.5 cm, sourced either from JPL (Jet Propulsion Laboratory) or from NASA.
