Large Craters on Dione - Universe Today
This Cassini photograph shows several of the large craters that pockmark Dione, one of Saturn's moons. The most prominent crater in the image is 188 km (73 mile) Dido, and the smaller crater above it is Antenor. On the sunlit side you can see some of the wispy markings, which Cassini has revealed to be a complex system of fractures in the moon's surface.
