Mariner 4 was launched on November 28, 1964, Mariner 4 performed the first successful flyby of the planet Mars, returning the first close-up pictures of the Martian surface. Mariner 4 captured the first images of another planet ever returned from deep space; their depiction of a cratered, dead planet largely changed the scientific community’s view of life on Mars. Other mission objectives were to perform field and particle measurements in interplanetary space in the vicinity of Mars and to provide experience in and knowledge of the engineering capabilities for interplanetary flights of long duration. Initially expected to remain in space for eight months, Mariner 4’s mission lasted about three years in solar orbit. On December 21, 1967, communications with Mariner 4 were terminated.
