NASA's Perseverance rover sets Mars distance record at 45.22 km, passing Opportunity

A new distance record

NASA says its Perseverance rover has now driven farther than any human-made vehicle on another world. Its odometer reached 45.22 kilometers on 11 October 2026, passing the 45.16 kilometers that the Opportunity rover covered on Mars between 2004 and 2018. The milestone came on Martian day 2006 of the mission, so Perseverance needed about five and a half years for a distance that took Opportunity close to 15. NASA announced the record on 12 October, and the rover had touched down on Mars on 18 February 2021. Opportunity remained operational until 2018, so the comparison is between a finished mission and one still running.

Driving itself across the terrain

Much of the distance is credited to AutoNav, the rover's autonomous navigation system. It images the ground as it moves, builds a 3D map of hazards and sets its path between waypoints chosen by planners on Earth, a capability the team describes as thinking while driving. NASA says more than 90 percent of Perseverance's total distance was covered with AutoNav steering, against about 5 percent for the first AutoNav system flown on Opportunity and its twin Spirit. Each observation processes 600,000 measurement points, while Sojourner, the first NASA rover on Mars, assessed its route using 20. At or near top speed the rover can cover up to 412 meters in a single Sol, the Martian day. Engadget reports that the team now wants to overcome camera glare from sunlight, which impedes the rover's vision and limits how long it can work each day.

Lac de Charmes and the Idubi site

The rover was traveling toward a site called Idubi, crossing a region along the western edge of Jezero crater known as Lac de Charmes. Scientists there are examining rocks and terrain they consider among the oldest ever explored in the solar system. NASA explains that their equivalents on Earth were erased long ago by erosion and plate tectonics, processes that do not happen on Mars. The science team's hope is that Idubi will reveal traces of ancient hydrothermal systems. The agency put the purpose of the site in its own words.

Idubi is where the science team hopes to find traces of ancient hydrothermal systems.

Mission outlook and rival rovers

The original plan called for about 20 kilometers, and NASA says the rover has far exceeded that figure. Steven Lee, project manager for the Curiosity and Perseverance rovers at NASA's Jet Propulsion Laboratory in California, told Reuters that the instruments are in very good condition and that all backup systems are usable. After evaluating all systems, Lee concluded the rover could keep working well into the 2030s. The mission has been extended to at least the end of 2028, and the rover cost about 2.5 billion dollars and took eight years to develop. Perseverance carries instruments that search for signs of ancient microbial life and collects rock and soil samples for possible return to Earth on future missions.

Curiosity, which has covered 38.15 kilometers since its landing in 2012, remains active in Gale Crater near the Martian equator. Among other distances, the chart compares the Russian lunar rover Lunochod 2, which covered 39 kilometers in 1973, and the Apollo 17 rover, which went farthest of the crewed lunar vehicles at 35.74 kilometers.
