Perseverance Rover Becomes the Farthest-Travelling Vehicle in Planetary History

On 11 October, NASA's Perseverance rover crossed 28.10 miles (45.22 kilometres) of Martian terrain, breaking the record of 28.06 miles (45.16 km) previously held by the Opportunity rover. While Opportunity needed 14 years to cover that distance, Perseverance achieved the milestone in just five and a half years — the greatest driving distance ever recorded on any world beyond Earth.

The rover was originally designed to travel only about 20 kilometres, meaning it has already more than doubled its intended range. Rover driver Mark Maimone of NASA's Jet Propulsion Laboratory said the team is confident Perseverance could eventually reach 100 kilometres in total, roughly doubling the distance already covered. Deputy project scientist Vivian Sun noted that all of Perseverance's science instruments remain essentially intact, describing the team as a "well oiled machine" after five years on Mars and crediting the mission's success to close collaboration between engineers, rover drivers and scientists.

Perseverance landed on the floor of the 28-mile-wide (46 km) Jezero Crater in February 2021, building on experience gained from earlier rovers including Sojourner, Spirit, Opportunity and Curiosity. The team is now heading southward along the crater rim toward a region called Rainbow Falls, where kaolinite clay minerals — formed when water interacts with rock — may hold clues about ancient water conditions in Jezero and the possibility that Mars once supported life.
