SUMMARY: NASA's Cassini spacecraft has obtained the most detailed images ever taken of Saturn's rings, including new details about its B ring, of which little was known previously. Cassini went behind Saturn's rings on May 3, 2005, and this gave scientists on Earth a chance to probe the ringst. Cassini sent a series of radio signals as it traveled behind the rings; the weaker the signal, the more dense the material in the rings. This allowed scientists to determine the thickness and size of particles at each point in the rings.

These are cool experiments. It will be interesting to see if there are any changes in the ring structure during the years that Cassini is out there making measurements.
