This is Tethys, a 662-mile-wide moon of Saturn captured by Cassini’s cameras in this raw image from May 14. Dominating its face is the huge Odysseus Crater, its rim gleaming in the sunlight. Much of Tethys is estimated to be water ice, due to its density and high albedo (reflectivity).
That Tethys was able to survive the impact that created the Odysseus Crater without shattering suggests that the moon was still in a partially molten state when it was struck. The crater is nearly 250 miles across, almost two-fifths the diameter of the entire moon!
