NASA's Cassini spacecraft is returning close-up images of the surface of Saturn's icy moon Enceladus after flying very close to the moon earlier this week. Cassini passed just 50 kilometers from the surface of Enceladus on Monday, a close flyby designed to provide high-resolution imagery of the moon's terrain. Images returned by the spacecraft have provided sharper looks at "tiger stripes", fissures in the region of the moon's south pole linked to geysers that erupt from the surface.
