Eleventh picture of Mars from Mariner 4 (in "raw" state) taken through the green filter from 7800 miles away showing a crater 75 miles in diameter in the Atlantis region.
Mariner 4 was the first spacecraft to get a close look at Mars. Flying as close as 9,846 kilometers (6,118 miles), Mariner 4 revealed Mars to have a cratered, rust-colored surface, with signs on some parts of the planet that liquid water had once etched its way into the soil. Mariner 4 was launched on November 28, 1964 and arrived at Mars on July 14, 1965.
