Life-size model of Mariner 4.
Until July 1965, no pictures of the surface of Mars had been sent back by the previous failed missions. Mariner 4 successfully flew by Mars on July 14 and 15, 1965. The spacecraft zoomed by at 9846 km from the surface. Pictures returned to Earth showed a heavily cratered surface reminiscent of the Moon, dashing the hopes of many Sci-Fi fans hoping for the chance of life on the red planet.
