Saturn's moon Mimas can be seen above the planet's rings in this image taken by NASA's Cassini spacecraft. Even at this extreme distance, the giant crater known as Herschel can be seen on the right side of the moon. Fine details of the thousands of smaller ringlets can be seen inside the rings themselves. The Cassini space probe was launched on October 15, 1997 and arrived at Saturn on July 1, 2004 on a mission to study and photograph Saturn and its moons. It has provided us with some of the most breathtaking views of the Saturnian system ever seen by mankind.
