Sojourner / Pathfinder Mars Rover

This mission was the first of a series of missions to Mars that included rovers, and was the first successful lander since the two Vikings landed on the red planet in 1976. Pathfinder was an American spacecraft that landed a base station with a roving probe on Mars in 1997. It consisted of a lander, renamed the Carl Sagan Memorial Station, and a lightweight 10.6 kg/23 lb wheeled robotic Mars rover named Sojourner .
