This map of the surface of Saturn's moon Dione illustrates the regions that will be imaged by Cassini during the spacecraft's very close flyby of the moon on Oct. 11, 2005. At closest approach, the spacecraft is expected to pass approximately 500 kilometers (310 miles) above the moon's surface. Dione is 1,126 kilometers (700 miles) across.
