Each mission contributed to the broader knowledge of Mars, with Mars 7 specifically designed to land on the Martian surface and transmit data back to Earth. The spacecraft consisted of an orbiter and a lander; however, Mars 7 was unique in that it was intended to perform a soft landing.

1973年8月9日 · Mars 7's lander separated from the flyby bus on 9 March 1974. Initially, it failed to separate. However, it was eventually released to begin its descent. Due to a retrorocket failure, the probe missed the atmosphere of Mars, and, instead of landing, flew past along with the coast stage, with a closest approach of 1,300 km (810 mi).[4]
