Rover (space exploration)
A rover is a vehicle that travels on the ground of a planet, moon, or other astronomical object. Some rovers carry people that drive them. Most are robots that can drive themselves for short distances, but humans on Earth give them directions each day about where to go and what to do.  They are electric vehicles, either using solar power or nuclear power.
