I see ice on Saturn's Moon Rhea!
Saturn's moon Rhea [REE-a] is an icy body with a rocky core taking up less than one-third of the moon's mass, with the rest composed of water-ice. Rhea is somewhat similar to Dione. Rhea is heavily cratered with bright whispy markings. This color-enhanced image was taken by the Cassini spacecraft. |

Rhea's cratered surface was already ancient before any complex life developed on Earth. The terrain seen here has probably changed little in the past billion years. Image by the Cassini spacecraft. |

Cassini captured this closeup of Rhea's cratered surface. |
