Atlas V 541 | MSL (Curiosity)

The Mars Science Laboratory (MSL) mission, featuring the renowned Curiosity rover, was designed to assess the planet's past and present habitability. Equipped with an array of advanced scientific instruments, including a drill and a sample analysis unit, Curiosity explored the Gale Crater, a site believed to contain evidence of ancient Martian environments. It delivered groundbreaking discoveries, including the detection of organic molecules and the confirmation of an ancient, potentially habitable lake bed.
