Perseverance just broke Opportunity's distance record, clocking 28.10 miles on Mars. The odometer officially makes it NASA's longest-driving rover ever. Wild to think about the engineering behind keeping wheels functional across that much Martian terrain—dust storms, rocks, temperature swings. Each mile is basically a stress test for autonomous navigation systems and power management. Opportunity lasted 14 years doing this. Perseverance is moving faster with better hardware and smarter path planning algorithms.
