No, this isn’t a picture from Mars. It’s from Titan, Saturn’s largest moon. This view taken by the Huygens lander on the moon’s surface shows pebble-sized objects thought to be rocks or ice blocks. The two objects just below the middle of the image are about 150 mm and 40 mm across, respectively, and are about 840 mm from Huygens. The surface is darker than originally expected and made up of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of the objects.
