PASADENA, Calif., May 20 (UPI) -- NASA says its Mars rover Curiosity has drilled a hole in a second rock target to gather samples for analysis in the rover's internal science lab instruments.
In only the second time a sample has been collected from inside a rock on Mars, Curiosity used the drill on its robotic arm to collect a sample from the interior of a rock dubbed "Cumberland," NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Monday.
