description Mars 7 Overview
Mars 7 was a Soviet Mars mission launched on August 9, 1973, as a combined flyby spacecraft and lander. The carrier was intended to conduct measurements during a close pass while the descent module entered the Martian atmosphere and landed on the surface. A malfunction prevented the lander from carrying out the maneuver needed for atmospheric entry, so it missed Mars; the carrier and lander continued in heliocentric, or Sun-centered, orbits. The mission is therefore recorded as a failed landing attempt rather than a surface mission.
