This radar image of the surface of Saturn's moon Titan was acquired on October 26, 2004, when the Cassini spacecraft flew approximately 994 miles (1,600 kms) above the surface. Brighter areas may correspond to rougher terrains and darker areas are thought to be smoother. This image highlights some of the darker terrain, which the Cassini team dubbed "Si-Si the Cat." This nickname was chosen after a team member's daughter, Si-Si, pointed out that the dark terrain has a cat-like appearance. Image Credit: NASA/JPL
