Mariner 4

Mariner 4 design model, photographed at NASA's Lewis Research Center in June 1964 The tall lattice mast carried a magnetometer, and the camera sat underneath the body pointing down. Mariner 4 launched on November 28, 1964, and flew past Mars in July 1965, returning 21 complete pictures plus part of a 22nd. They were the first close-up photos of another planet, and their cratered, Moon-like ground ended hopes of canals and an Earth-like Mars.
