|The southern hemisphere of Enceladus, a moon of Saturn. Recent data from the Cassini
spacecraft revealed geyser-like plumes, intense heat flux, and tectonic features
including large fractures that cut across the pole, a ring of ridges (red), and
radial rifts (blue). The origin of these tectonic features and the relation among
the tectonic features, the heat transport, and the plumes is discussed by using a
unified thermo-mechanical model of Enceladus.
