Rover (space exploration)

Planetary surface exploration vehicle

A rover (or sometimes planetary rover) is a planetary surface exploration machine designed to move over the rough surface of a planet or other planetary-mass celestial bodies. Some rovers have been designed as land vehicles to transport members of a human spaceflight crew; others have been partially or fully autonomous robots. Rovers typically land on a planet other than Earth or a moon via a lander-style spacecraft, tasked to move around and collect information about the terrain, and to take crust samples such as dust, soil, rocks and even liquids.
