Watch as NASA's Curiosity Rover frees its drill from a rock

This series of images shows NASA's Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm, and-after waving the arm and running the drill a few times-finally detached the rock. The imagery showing the entire process was captured by the black-and-white hazard cameras on the front of Curiosity's chassis and by navigation cameras on its mast (head).
