Mars Rover Drills Into First Rock

Curiosity's mission on the red planet continues

NASA's Mars rover Curiosity has pounded into a Red Planet rock with its drill for the first time, bringing the 1-ton robot a big step closer to initiating its first full-bore drilling operations.

The Curiosity rover hammered the rock using the arm-mounted drill's percussive action over the weekend, completing another test along the path toward spinning the bit and biting into rock for the first time.
