This false-colour view taken by NASA's Cassini spacecraft shows the surface features and color variation on the moon Telesto. Similar to Pandora, the smooth surface of this Trojan moon suggests that it's covered with a mantle of fine, dust-sized icy material. The small moon Telesto is about 24 kilometers (15 miles) wide. Cassini captured this image at a distance of approximately 20,000 kilometers (12,000 miles) with its narrow-angle camera on December 25, 2005.
