Mars Viking Mission
This video clip from NASA examines space exploration by the Viking missions to Mars and considers if life can exist on the Red Planet. After describing the components of the Viking orbiters and landers, the programme notes how scientific experiments performed on the surface of Mars revealed a lack of organic material in the Martian soil. The data gathered by Viking 1 and Viking 2 served as the basis for all future research into a possible manned spaceflight mission to Mars.
