.STL and .CATProduct provided... A Mars rover is an automated motor vehicle which propels itself across the surface of the planet Mars upon arrival. Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months and they can advance the knowledge of how to perform very remote robotic vehicle control. There have been four successful robotically operated Mars rovers. The Jet Propulsion Laboratory managed the Mars Pathfinder mission and its now inactive Sojourner rover. It currently manages the Mars Exploration Rover mission's active Opportunity rover and inactive Spirit, and, as part of the Mars Science Laboratory mission, the Curiosity rover.
