As fun as it would be to visit Mars, we wouldn't necessarily want to walk a mile in the Curiosity rover's shoes — or rather, its wheels. After landing in Mars' Gale Crater in 2012 and traveling some 20 miles (32 kilometers) over the rocky Martian landscape, the robotic explorer's six wheels are looking a little worse for wear.
The latest wheel photo, taken by Curiosity's Mars Hand Lens Imager (MAHLI) on Sept. 22 shows quite a bit of damage — some of which appears to be new — from smaller dents and punctures to major tears and gashes.
