NASA's Curiosity rover has beamed back its first color photograph from Mars. The image is of a pebbly landscape and the rim of the Gale Crater in the distance. The rover took the photo with a camera at the end of its robotic arm. Curiosity snapped the photo on its first day on the surface after touching down Sunday night. Parma-based GrafTech International helped develop Curiosity's heat shields, and the NASA Glenn Research Center in Cleveland developed and tested the rover's elaborate parachute landing system. Center spokesperson Ann Over says researchers were delighted when the rover made a safe landing on the Martian surface.
