Rank 18 documents Perseverance — the Mars 2020 rover that landed in Jezero crater on 18 February 2021, carrying 43 sample tubes, PIXL and SHERLOC instruments, MOXIE oxygen demonstration hardware, and the Ingenuity helicopter that achieved the first powered flight on another planet. Ken Farley's science team and JPL engineers reused MSL sky-crane heritage while adding sample cache depots for a future Mars Sample Return campaign. Perseverance explores an ancient river delta where orbital data promised preserved biosignature potential, documenting bedrock while Ingenuity completed dozens of flight sorties. Wallimilist renders the sample tube tray, airborne Ingenuity, and Jezero delta hero exactly as the master PNG dictates — 2021 kicker, SAMPLE CACHE + HELICOPTER label, and curator copy on Mars 2020 heritage.
