Ring scientists have been waiting for this. Finally, after more than two years orbiting Saturn, the Cassini spacecraft reaches one of the ultimate vantage points. The rings should shine with majesty worthy of the "Jewel of the Solar System." |

The H ring seems much darker and less reflective than the E ring, even (or maybe especially) in this lighting. I'd think this would argue against it being a pure-ice ring. Perhaps it is formed of icy/rocky debris from impacts on Janus and Epimetheus? I guess my first impression is that it's more of a dust ring that an ice ring.
