Radial Channels Carved by Dry Ice
Spider-shaped features in the south polar region of Mars are carved by vaporizing dry ice in a dynamic seasonal process. This image from NASA's Mars Reconnaissance Orbiter includes several of the distinctive features in an area 1.2 km wide. The features are cut into the ground, not built up above the surrounding surface. Sunlight is coming from the right, from about 15 degrees above the horizon. ASU-IPF-3028
