Saturn's Recycling Rings
| Description |
This is an artist concept of a close-up view of Saturn's ring particles. |
| Full Description |
This is an artist concept of a close-up view of Saturn's ring particles. The planet Saturn is seen in the background (yellow and brown). The particles (blue) are composed mostly of ice, but are not uniform. They clump together to form elongated, curved aggregates, continually forming and dispersing. The space between the clumps is mostly empty. The largest individual particles shown are a few meters (yards) across. 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. The ultraviolet imaging spectrograph was designed and built at, and the team is based at the University of Colorado, Boulder.

| Full Description |
This is an artist concept and movie of the view from Cassini during the star occultation that detected "Mittens," the small object to the right of the star. As Cassini watched the star pass behind Saturn's F ring (foreground), the star blinked out when Mittens blocked it, indicating it may be a solid moonlet.

| Full Description |
This is a computer simulation of the final stage of the growth of a "clump" in Saturn's rings. The gravity from a hypothesized moonlet (solid gray sphere in frame center) has collected smaller ring particles (black) to form a temporary aggregation. The particles shown in the simulation are from centimeters to meters (inches to yards) across. The gray moonlet is 61 meters (200 feet) across.
