NASA's Perseverance rover has driven 28.10 miles on Mars, surpassing the record held by Opportunity. The rover achieved this in 5.5 years, aided by autonomous navigation systems.
NASA's Perseverance Mars rover has broken the record for the most miles driven on a world beyond Earth. On Oct. 11, the rover's odometer hit 28.10 miles (45.22 kilometers), eclipsing the previous record of 28.06 miles (45.16 km) set by NASA's Opportunity rover. While Opportunity took 14 years to cover that distance, Perseverance achieved the milestone in just 5.5 years since landing in February 2021.
The rover's ability to drive autonomously has been a key factor in its efficiency. According to NASA, the rover uses a system called AutoNav, which allows it to process images and select the safest path without human intervention for each segment. Steven Lee, the project manager for NASA's two Mars rovers, stated that 90 per cent of Perseverance's drives are done autonomously.
"Perseverance takes stereo images of the terrain ahead, generates a 3D software map, and selects the safest path towards a drive goal," Lee said. He noted that this contrasts with previous rovers, which needed to pause to "think" before each drive segment.
NASA says that this "thinking while driving" capability allows Perseverance to maintain its top speed while rolling around obstacles, enabling it to travel up to 412 metres each Martian day. Mark Maimone, a rover driver at NASA's Jet Propulsion Laboratory (JPL), emphasized the rover's improved autonomy in a mission blog post: "The rover that broke this record did so by making its own decisions about the path. Given the autonomy to just go, Perseverance is a better driver than the one that landed, and we're not done."
Despite exceeding its original design parameters, the rover remains in good condition. "Our original design was only planned to last for [about] 20 kilometers of driving," Maimone told Space.com. "We've more than doubled that already … and we're looking really good to go for up to 100 kilometers total."
Steven Lee confirmed that a recent assessment concluded the systems are "capable of operating well into the 2030s, likely beyond." Lee added that mobility system mechanisms are being tested to show the rover can drive 100 km (62 miles) or more, with hardware tested to the equivalent of 150 km to 300 km (93 miles to 186 miles).
Vivian Sun, the mission's deputy project scientist, noted that "all of Perseverance's original capabilities are more or less intact, especially for the science instruments." She attributed the mission's endurance to teamwork, stating, "The magic sauce for our operations team is how cohesively we work together."
Perseverance is currently exploring Jezero Crater, a region believed to have hosted a lake billions of years ago. The rover is heading south along the crater rim toward an area called "Rainbow Falls," which is thought to contain kaolinite, a clay mineral that forms when water interacts with rock.
"Whenever we are looking at clay minerals, I think the question of habitability and the search for potential biosignatures is always on the table," Sun said. The team also plans to investigate an area called Idubi, where scientists hope to find evidence of ancient hydrothermal systems. Perseverance is expected to remain in the Idubi area, collecting rock samples, until the end of 2028.
