NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland." Plans call for delivering portions of the sample in coming days to laboratory instruments inside the rover. This is only the second time that a sample has been collected from inside a rock on Mars.
