An anonymous reader writes "In August 2012, the Nasa rover Curiosity is scheduled to touch down on the surface of Mars. The size of a small car, it's four times as heavy as predecessors Spirit and Opportunity, and comes with a large robot arm, a laser that can vaporise rocks at seven metres, a percussive drill and a weather station. Oh, and 4.8kg of plutonium-238. Wired has some high-resolution photographs from lab that is putting the next rover together."
