Mars 2020 is a NASA mission that includes the rover Perseverance, the now-retired small robotic helicopter Ingenuity, and associated delivery systems, as part of the Mars Exploration Program. Mars 2020 was launched on an Atlas V rocket at 11:50:01 UTC on July 30, 2020, and landed in the Martian crater Jezero on February 18, 2021, with confirmation received at 20:55 UTC. On March 5, 2021, NASA named the landing site Octavia E. Butler Landing. As of 9 April 2024, Perseverance has been on Mars for 1115 sols. Ingenuity operated on Mars for 1042 sols before sustaining serious damage to its rotor blades, possibly all four, causing NASA to retire the craft on January 25, 2024.
