Mariner 9 Close-up of Mars
Date: 14 Nov 1971

Pictured here is a a Martian shield volcano, approximately 25 miles across at the crater, which was photographed consecutively by Mariner 9 with the wide-angle and telephoto lenses. The summit crater and groves down the flank probably were produced by subsidence flowing subsurface movement of magma.

Mariner 9 was the first spacecraft to orbit another planet. The spacecraft was designed to continue the atmospheric studies begun by Mariners 6 and 7, and to map over 70% of the Martian surface from the lowest altitude (1,500 km [900 miles]) and at the highest resolutions (1 km per pixel to 100 m per pixel) of any previous Mars mission

Mariner 9 was launched on 30 May 1971 and arrived on 14 November 1971.
