NASA's Curiosity rover is a robotic vehicle designed to explore the surface of Mars. Launched in 2011, it landed in the Gale Crater in August 2012. Its primary mission is to investigate the planet's climate and geology, and assess whether Mars ever had conditions suitable for life. Equipped with advanced scientific instruments, Curiosity can analyze soil and rock samples, capture high-resolution images, and measure atmospheric conditions. The rover has made significant discoveries, including evidence of ancient water flows, which suggest that Mars may have once supported microbial life.
