Curiosity Rover Snaps Stunning Mountain Vista on Mars (Photo)

NASA's Mars rover Curiosity has beamed home a gorgeous postcard of the mountainous Red Planet landscape it's exploring. The car-size Curiosity rover has been studying the foothills of the 3.4-mile-high (5.5 kilometers) Mount Sharp since September 2014. Slowly but surely, the robot is making its way up the mountain, and the new photo — which was taken on Sept. 9 but just released Friday (Oct. 2) — shows some of the terrain Curiosity will investigate in the future.
