On the Cover: <i>Cassini</i>, like all robotic explorers we launch into deep space, has deepened our understanding of our solar environs in many ways—some anticipated and some not. Dialing up Cassini’s infrared, green, and ultraviolet filters draws out details in the surfaces of Saturn’s icy moons that we cannot see in natural color wavelengths. This map of Enceladus’ far side shows the redepositon of icy dust (pink and yellow) from the “tiger stripe” vents (cyan tinted) at the moon’s South Pole.
