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.
The rover is turned out of the field of view of Earth and goes dark, just like nighttime on Earth, when the sun goes out of the field of view of Earth at a certain location when the Earth turns its back to the sun. The orbiters can see Earth for about 2/3 of each orbit, or about 16 hours a day.
