Three icy moons of Saturn

Three icy moons of Saturn

. Cameras aboard the Voyager 2 spacecraft obtained these pictures of three ice-covered moons of Saturn in 1980. They are Mimas (left), Enceladus (middle) and Tethys (right) with respective radii of 196, 255 and 530 thousand meters. The surfaces of all three satellites are covered with water ice. They contain the cratered scars of past impacts as well as relatively young, smooth regions. (Courtesy of NASA and JPL.)
