Soviet Mars Landers

Landers sent to the surface of Mars by the Soviet Union, whose Mars program often flew a lander together with a coast stage or an orbiter on one bus spacecraft, such as Mars 6, a 3MP bus spacecraft made of a lander and a coast stage that studied Mars as it flew past. A lander belongs here when its cited source calls it a Soviet spacecraft carrying a Mars lander. The stationary landers of NASA have a group of their own in this subcategory, and paired orbiter and lander missions are listed in the orbiter and lander subcategory.
