NASA’s Perseverance rover has set a new record for the longest distance driven by a vehicle on the surface of any world beyond Earth, having traveled 45.2 kilometers (28.1 miles) on Mars since its landing in February 2021. This milestone, achieved after five and a half years of exploration, surpasses the previous record held by NASA’s Opportunity rover, which covered 45 kilometers from 2004 to 2018. Both Perseverance and Opportunity have also exceeded the driving distances of lunar rovers.
The six-wheeled rover, about the size of a small car, is currently exploring Jezero Crater, located in Mars’s northern hemisphere. This region is believed to have hosted a lake basin billions of years ago, offering conditions potentially conducive to microbial life. Perseverance is conducting detailed surveys in the area known as Lac de Charmes, near the crater’s western rim en route to a site called Idubi. These locations contain some of the oldest terrain explored in the solar system and may provide insights into early planetary geological processes, including the impact of large meteorites and potential ancient subsurface hydrothermal systems.
Steven Lee, project manager for the Perseverance and Curiosity rovers at NASA’s Jet Propulsion Laboratory in California, stated that the rover’s engineering hardware and scientific instruments remain in excellent condition, with all redundant systems operational. A recent system assessment suggested that Perseverance could continue functioning well into the 2030s, potentially enabling further extensive exploration beyond its originally planned 20-kilometer driving mission.
Perseverance’s success has been attributed largely to its autonomous navigation system, called AutoNav, which enables the rover to independently plan and execute approximately 90% of its drives without direct human control. The rover uses stereo imaging to create three-dimensional maps of the terrain and select the safest routes. This capability is enhanced by a high-speed co-processor known as the Vision Compute Element, which allows near-continuous image processing during drives, contrasting with earlier rovers that had to pause frequently to process data.
In addition to Perseverance, NASA’s Curiosity rover continues to operate on Mars, exploring Gale Crater near the equator and having traveled about 38 kilometers since landing in 2012. Other missions, such as China’s Zhurong rover, have also contributed scientific data while operating in the Martian northern lowlands in 2021 and 2022.
Among Perseverance’s significant scientific achievements is the discovery announced in 2025 of a potential biosignature in reddish sedimentary rock formed 3.2 to 3.8 billion years ago within an ancient river channel feeding Jezero’s lake basin. This finding raises intriguing possibilities about past microbial life on Mars.
NASA has recently approved an extension of Perseverance’s mission to continue exploring the crater rim until approximately the end of 2028. The rover’s plutonium-based power source is performing as expected, providing many more years of energy to support ongoing scientific operations and driving tests, including those designed to demonstrate its capability to travel well beyond 100 kilometers in total.
