NASA's Perseverance rover is now the farthest-traveling vehicle ever to operate on another world. On Oct. 11, the six-wheeled explorer's odometer ticked past 28.10 miles (45.22 kilometers), edging ahead of the 28.06-mile (45.16-kilometer) mark set by its predecessor, Opportunity, according to a mission update from NASA's Jet Propulsion Laboratory.
The record-breaking drive, a 299.6-foot (91.3-meter) stretch logged on the rover's 2,006th Martian day, or sol, since its February 2021 landing, means Perseverance reached in roughly five and a half years what took Opportunity almost 15, from 2004 until it fell silent in a dust storm in 2018. NASA also notes Perseverance has now outdistanced the lunar rovers driven by Apollo 17 astronauts (22.2 miles) and the Soviet Union's robotic Lunokhod 2 (24.2 miles), making it the longest-traveled vehicle on any surface beyond Earth.
A rover that mostly drives itself
JPL credits much of the pace to AutoNav, the rover's autonomous terrain-evaluation system, which has steered more than 90% of Perseverance's total mileage, compared with roughly 5% for the rudimentary autonomy available to Opportunity and its twin, Spirit. The original 2020 mission plan called for Perseverance to drive no more than about 12.4 miles over its primary mission. "We've blown well past that," said Steven Lee, project manager for Perseverance and Curiosity at JPL, who added that drives of this scale have become "routine" as the technology matured. Mark Maimone, the mission's deputy team chief for robotic operations, put it more bluntly: "Perseverance is a better driver than the one that landed, and we're not done."
Independent coverage of the milestone, including a report from Guinness World Records and astronomy outlet Sci.News, confirms the same distance figures and timeline drawn from NASA's own tracking data.
The milestone is a mobility record, not a scientific one — Perseverance's primary job remains collecting rock and soil cores from Jezero Crater that could eventually be returned to Earth, a campaign that still depends on a future NASA-ESA sample-return mission whose design and funding remain unsettled. For now, the rover is rolling through a region nicknamed Lac de Charmes toward a site called Idubi, where scientists hope to find evidence of ancient hydrothermal activity, before turning south toward a roughly 100-meter outcrop of ancient crust called Rainbow Falls.
NASA has approved Perseverance's first mission extension, which began this month and is expected to run through roughly the end of 2028, keeping the rover exploring the crater's rim for at least two more years. Given AutoNav's growing role and the terrain ahead, NASA says it expects the odometer record to keep climbing "for many years to come."
