Mars Rovers

The video discusses NASA's Mars missions, initially planned for 90 days but still ongoing, providing insights into Mars' geology. The missions, led by Cornell University, involved sophisticated technology to deliver the Rovers, Spirit and Opportunity, to Mars. They relied on solar panels, which were expected to fail due to dust storms, limiting mission life. The Rovers were launched in 2003, with Spirit landing using parachutes and airbags, exploring Mars' Gussev Crater.
