NASA's most advanced rover yet has now been poking around on Mars for a full year, and finding all kinds of clues to the Red Planet's past.
Curiosity is also equipped with plenty of power tools, even though you could argue that the rover itself is basically the most awesome power tool ever. Here, it shows off the first sample of powdered rock extracted from the surface by its drill. Curiosity's onboard lab has been doing chemical analysis on samples like this.
Scientists liken the ability to drill to opening a time capsule and examining the makeup of Martian rock that hasn't been subjected to the elements recently, perhaps for billions of years.
