COVER Saturn's enigmatic moon Enceladus is a jumbled world of fresh snow plains, old cratered terrains, and long cracks dusted in green organic material. A special section in this issue presents multiple views of Enceladus taken from the Cassini spacecraft during three close flybys. See page 1388. Image: NASA/Jet Propulsion Laboratory/C. C. Porco
