Photos: Mars rover Curiosity

Curiosity, NASA's Mars rover used the equivalent of a dust broom on its robotic arm to sweep away reddish, oxidized dust, revealing this gray patch of rock that resembles a paving stone. The rock is called "Bonanza King" and the rover team wants to use it as the rover's fourth drilling target, if it passes an evaluation by engineers. The photo was taken August 17, 2014, using the rover's mast camera, or Mastcam. Click through to see more of its images.
