Which Mars rover set a one-day drive record of 220 meters in 2005?

Opportunity set the one-day Mars driving record of 220 meters in 2005. The record-setting drive took place on March 20, 2005, as the rover crossed relatively smooth terrain in Meridiani Planum.

Opportunity and its twin, Spirit, were built for NASA’s Mars Exploration Rover mission and designed to operate for about 90 sols. Opportunity’s landing area offered broad, comparatively navigable plains, allowing mission planners to schedule long drives while still stopping to photograph and analyze rocks, soil, and geological features.

The record is often associated with 219 meters in technical reports or 220 meters when rounded, so the quiz’s figure is the standard public-facing value. It was a one-sol record, not the rover’s total distance. Opportunity eventually traveled 45.16 kilometers overall. Its single-day record stood for many years before later Mars missions, including Perseverance, drove farther in one Martian day.
