Mars rover Curiosity sustains wheel wear but keeps exploring
Since touching down on Mars in 2012, NASA's Curiosity rover has begun to show the effects of its long-term surface exploration. Recent photos reveal dents and fractures on the rover's wheels, a result of navigating jagged rocks and harsh ground. Even with this wear, Curiosity is still fully functional and has covered more than 32 km as it carries on with its investigation of the Martian environment.
