Cassini just went by Enceladus, the little icy moon of Saturn with water volcanoes, getting down to just 50 km from the surface. It got pictures of the south polar regions in hopes of getting a close look at those tiger stripes that vent out water ice particles. These pictures have plenty of shadows, making it easy to see surface relief.
