Abstract: A rover is a planetary surface exploration device designed to move across solid surfaces on a planet or other planetary mass celestial bodies. Rovers have wheels and specialise in moving around. They land on the surface of a planet and drive around to different spots. Scientists use rovers to further their understanding of the composition of the planet's various regions. They are typically deployed for scientific objectives, such as gathering soil samples, looking for bacteria living on a planet's surface, discovering evidence of water, and attempting to determine whether the planet contains any signs of life. Over stationary landers, rovers offer a number of advantages: they explore more ground, can be steered to interesting sites, can position themselves in sunny areas to survive the winter, and can improve our understanding of how to handle very remote robotic vehicles.
