  As it approached Saturn near the end of its second orbit, Cassini caught this view of the small, irregularly shaped moon Hyperion (270 kilometers, 168 miles across). The moon's long axis is nearly horizontal in this view. The image shows parts of Hyperionís day and night sides.

Hyperion is a heavily cratered body, though Cassiniís cameras were not able to discern much detail from the distance at which the image was taken. The spacecraft is slated to fly past the little moon at an altitude of less than 1,000 kilometers (620 miles) in late 2005.

The image was taken in visible light with the narrow angle camera on September 29, 2004, from a distance of 5.9 million kilometers (3.7 million miles) from Hyperion and at a Sun-Hyperion-spacecraft, or phase, angle of 75 degrees. The image scale is 35 kilometers (22 miles) per pixel. The image has been magnified by a factor of four to aid visibility.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
