From publisher blurb: From space at a distance, orange and blue atmospheric haze layers surround Titan. On a closer look from orbit, Titan has an atmospheric polar vortex — a swirling hydrogen cyanide (HCN) gas cloud — over the moon’s south pole. Upon closer examination, seasonal methane rainstorms produce wet patches visible from orbit. At the surface, rust-colored clouds appear in a blue sky. The clouds are made of methane ice and cyanide gas. The surface appears orange with white boulders and rocks. The plentiful boulders are rock-hard water ice.
