The Viking program consisted of a pair of identical NASA space probes, Viking 1 and Viking 2, which arrived on Mars in 1976. Each spacecraft was composed of two main parts: an orbiter designed to photograph the surface of Mars from orbit, and a lander designed to study the planet from the surface. The orbiters also served as communication relays for the landers once they touched down. Viking 1 lasted from 1975-1982, while Viking 2 lasted from 1975-1980
