<P> A rover ( or sometimes planetary rover ) is a space exploration vehicle designed to move across the surface of a planet or other celestial body . Some rovers have been designed to transport members of a human spaceflight crew ; others have been partially or fully autonomous robots . Rovers usually arrive at the planetary surface on a lander - style spacecraft . Rovers are created to land on another planet , besides Earth , to find out information and to take samples . They can collect dust , rocks , and even take pictures . They are very useful for exploring the universe . </P>
