説明
Perseverance is NASA's most advanced Mars rover, designed to search for signs of ancient microbial life and advance understanding of Mars' habitability. Launched on July 30, 2020 and landing in Jezero Crater on February 18, 2021, it collects rock and regolith core samples for potential future return to Earth. The rover carries seven scientific instruments including SuperCam, PIXL, SHERLOC, and MOXIE — which demonstrated oxygen production from the Martian atmosphere. It also deployed Ingenuity, the first powered aircraft to fly on another planet.
