Dione Takes A Bite Out Of Tethys
Pasadena CA (SPX) Mar 14, 2006 Saturn's moon Dione steps in front of Tethys for a few minutes in an occultation event, something that occurs frequently in the Saturnian system, with its 34 known moons. NASA's Cassini spacecraft took the image Feb. 10 in visible light, from a vantage point close to Saturn's ring plane. Cassini captured the image with its narrow-angle camera at a distance of approximately 3.7 million kilometers (2.3 million miles) from Dione and 4 million kilometers (2.5 million miles) from Tethys. Resolution in the original image was 22 kilometers (14 miles) per pixel on Dione (1,126 kilometers, or 700 miles across) and 24 kilometers (15 miles) per pixel on Tethys (1,071 kilometers, or 665 miles across). Mission scientists magnified the image by a factor of two.

A Little Moon Of Saturn Makes Its Presence Known
Katlenburg-Lindau, Germany (SPX) Mar 13, 2006Enceladus measures only 500 km across, and is coated in a highly reflective layer made mostly of water ice. The NASA-led international Cassini mission is in orbit about Saturn, making countless new discoveries about the planet and its many moons. During 2005, Cassini's passed by Enceladus, and its instruments revealed the moon to be geologically active even today, billions of years after its formation. |
