description Mars 5 Overview
Mars 5 was a Soviet robotic spacecraft launched in 1973 as part of the Soviet Mars program.

A failure involving loss of pressure in the spacecraft ended operations before the planned observing work was complete, but the mission still contributed both visual and atmospheric data about Mars.
