A Mars rover is an automated motor vehicle which propels itself across the surface of the planet Mars after landing.
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 Mars rovers, all of them robotically operated. The Jet Propulsion Laboratory managed the Mars Pathfinder mission with its Sojourner rover. It currently manages the Mars Exploration Rover mission with its two rovers, Spirit and Opportunity, and also the Curiosity, which is part of the Mars Science Laboratory mission.

“Old Rover in his moss-greened house
Mumbles a bone, and barks at a mouse.”
