The Cassini spacecraft, which is orbiting Saturn, has taken the first close-up pictures of Saturns moon, Hyperion.
The images show that Hyperion has a reddish surface. It is dotted with craters and looks like a sponge. No one knows how it got that look.
Hyperions surface is unlike that of any of Saturns other moons.
Hyperion is 266 kilometres across, and has an irregular shape.
