NASA’s Curiosity rover, which landed on Mars in 2012, has traversed over 20 miles of the Martian surface, causing significant wear on its wheels. As of its 4,315th sol (Martian day), NASA engineers monitor the wheels’ condition using onboard cameras. Despite some holes and rough edges, the tread pattern remains intact. NASA has implemented strategies to extend the wheels’ lifespan, such as avoiding rough terrain and driving backward over difficult patches. Regular wheel check-ups are part of Curiosity’s maintenance routine.
