NASA's Mars rover Curiosity has used the drill attached to its robotic arm to drill a second time, this time collecting a powdered sample from the interior of a rock called "Cumberland".

The space agency's plans call for portions of the sample to be delivered to laboratory instruments inside the rover in the coming days. This is just the second time that a sample has been collected from inside a rock on the Red Planet.

The first time Curiosity drilled and collected a sample of powdered rock was three months ago when it drilled a target known as "John Klein." Cumberland resembles John Klein, and lies about nine feet further west. Both Cumberland and John Klein are within a shallow depression known as Yellowknife Bay.

Curiosity drilled the 2.6-inch deep hole into Cumberland on May 19.
