| Mission outcome | Landed in Gusev Crater and traversed 7.73 km over 2,208 sols — 24× its design lifetime. Found evidence of ancient hydrothermal activity at Home Plate. Became permanently immobile in soft soil in 2009; contact lost March 2010. | First spacecraft to demonstrate oxygen production on Mars (MOXIE). Collected and cached 24 sample tubes for eventual Mars Sample Return. Documented diverse rock types in Jezero's ancient river delta. Deployed and supported Ingenuity through 72 flights. | Confirmed ancient habitable environment at Gale Crater — lake sediments billions of years old with all ingredients for life. Discovered complex organic molecules and seasonal methane fluctuations. Still driving as of 2026, ascending the foothills of Mount Sharp. |
