A robot just ran a marathon on another planet. And it did it in half the time of the last one.
NASA's Perseverance rover has driven 26.2 miles (42.195 kilometers) across the surface of Mars, the exact distance of a full marathon. It reached the milestone on its 1,890th Martian day, or sol, after five years and four months of driving. That is less than half the time it took the previous record holder, NASA's Opportunity rover, which needed 11 years and two months to cover the same ground.
A tiny green speck in a vast red landscape
A new orbital image captured on June 13, 2026, shows Perseverance as a small green dot against the Martian terrain. The picture was taken by NASA's Mars Reconnaissance Orbiter (MRO) using its High-Resolution Imaging Science Experiment (HiRISE) camera. The image also reveals the rover's winding tracks snaking across the surface, a visible record of its long journey.
At the time the image was taken, Perseverance was operating west of Jezero Crater in a region the mission science team calls "Arbot." The rover reached the marathon distance just one day after the image was captured.
Who built the machines behind the milestone
NASA's Jet Propulsion Laboratory (JPL) in Southern California manages both Perseverance and the Mars Reconnaissance Orbiter for the agency's Science Mission Directorate. JPL is managed for NASA by Caltech. Lockheed Martin Space in Denver built the orbiter and continues to support its operations. The University of Arizona in Tucson operates the HiRISE camera, which was built by BAE Systems in Boulder, Colorado.
Perseverance landed on Mars in February 2021. Its primary mission is to search for signs of ancient microbial life and collect rock samples for possible return to Earth. The marathon distance is a side effect of that work, not a goal in itself. But it marks a clear measure of how far the rover has traveled while doing its science.
For the teams on Earth, the milestone is a reminder of the durability and pace of robotic exploration. A machine built in California has now outrun every other vehicle ever sent to another world, and it is still going.
