Saturn's Moon Tethys from Cassini

Tethys is a large, icy moon of Saturn, captured here by the Cassini spacecraft. It's composed almost entirely of water ice and features a massive impact crater that nearly circles the moon. The fact that this impact didn't shatter Tethys suggests it might have been at least partly liquid in its past. Two smaller moons, Telesto and Calypso, share Tethys's orbit.
