Mars Exploration Rover

The Mars Exploration Rovers, specifically Spirit and Opportunity, were robotic vehicles launched by NASA to study the Martian surface. They landed on Mars in 2004 and conducted extensive geological examinations, analyzing rocks and soil for signs of past water and potential life. Over their missions, both rovers greatly exceeded their expected lifespans, providing valuable data about Mars's environment and history. Their discoveries have contributed significantly to our understanding of the planet and paved the way for future explorations by humans and more advanced robotic missions.
