Stock Illustration Description:
Royalty-free NASA stock photo of plumes of water vapor and other gases escape at high velocity from the surface of Saturn’s moon Enceladus, as shown in this artist concept. The "shear heating" mechanism suggests that tidal forces acting on fault lines in the moon’s icy shell cause the sides of the faults to rub back and forth against each other, producing enough heat to transform some of the ice into plumes of water vapor and ice crystals. Cold sub-surface ice (blue) becomes much warmer near the active fractures from which the plumes emanate. Movement along the fault lines may be about half a meter (20 inches) over the course of the 1.37-day tidal period of Enceladus around Saturn. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. Photo Credit: NASA/JPL
