Mars rovers are robotic vehicles designed to explore the surface of Mars. They are equipped with various scientific instruments to analyze soil, rocks, and the atmosphere, helping scientists understand the planet's geology and potential for past life. Notable rovers include Spirit, Opportunity, and Curiosity. These rovers are remotely operated from Earth and can travel several kilometers over the Martian terrain. They send back valuable data and images, contributing to our knowledge of Mars' environment and climate. The latest rover, Perseverance, also carries a helicopter named Ingenuity to test powered flight in the thin Martian atmosphere.
