NASA’s Mars 2020 rover, named Perseverance, launched on July 30, 2020, and landed successfully in Jezero Crater on Mars on Feb. 18, 2021. It is the second NASA mission to be powered by a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG).
Perseverance is designed to seek evidence of past microbial life on Mars, such as rocks that formed in the presence of water and could preserve evidence of organic chemicals, the building blocks of life. The rover also will test technology related to future human exploration of Mars, and will gather samples of Mars that could be brought back to Earth by a future mission. It is the fifth rover sent to Mars by the United States, and builds upon the design heritage and continuing scientific discoveries of NASA’s Curiosity Mars rover.
