Six missions have operated on the Martian surface since 1997 — three simultaneously in 2022.

| Mission outcome | Europe's first Mars rover, designed to drill 2 m below the surface — deeper than any previous Mars mission — to search for biosignatures shielded from surface radiation. After the 2022 suspension of Russian cooperation, ESA rebuilt the mission with NASA support: on April 16, 2026, NASA formally began implementation of its contributions (Falcon Heavy launch services from LC-39A, braking engines for the landing platform, and radioisotope heater units), targeting a late-2028 launch and a ~2030 landing at Oxia Planum. | 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. | 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 June 2026 (~4,921 sols, 36.86 km), ascending the foothills of Mount Sharp. |
