Mars rover

A Mars Rover is a type of robot that is used to explore the surface of the planet Mars. The rovers look like small cars and have several instruments on them, like cameras and sensors, to help scientists learn more about the planet. Rovers send back pictures and data to Earth to help scientists see what the planet looks like and discover interesting things about its environment. They also search for signs of water or other forms of life that may exist there. Rovers are one way that scientists can explore Mars without having to send astronauts to go in person.
