The Viking program consisted of a pair of identical American space probes, Viking 1 and Viking 2, which landed 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.

What are the results of the Viking mission?
The results from the Viking experiments gave our most completeview of Mars. Volcanoes, lava plains, immense canyons,cratered areas, wind-formed features, and evidence of surface waterare apparent in the Orbiter images. The planet appears to bedivisible into two main regions, northern low plains and southerncratered highlands.
