Mariner 4

Mariner 4, launched by NASA on November 28, 1964, was a monumental success. It performed the first successful flyby of Mars on July 14, 1965, returning 21 historic images. These revealed a desolate, crater-filled, Moon-like landscape with a much thinner atmosphere than expected, fundamentally altering the scientific perception of the Red Planet.
