Mars Rovers

Mars rovers are automated, motorized vehicles that travel across the surface of Mars. They are much more useful than landers, which do not travel around. Rovers can explore more ground, be directed to interesting features, and place themselves in sunny positions to survive the winter months.

There have been four successful Mars rovers:


Voyager is a NASA mission, with two robotic spacecraft, Voyager 1 and Voyager 2. They were launched in 1977 to explore the far edges of our solar system. Both spacecraft were launched to investigate Jupiter and Saturn. Voyager 1 continued towards the farthest edge of the solar system.
