David Seal is Cassini's Mission Planner at the Jet Propulsion Laboratory and has been involved with the Cassini mission to Saturn since 1992. Dave developed JPL's Solar System Simulator and has also worked on the Shuttle Radar Topography Mission. Outside of JPL, Dave enjoys acting in Caltech theater, disc golf, and the science of soap bubbles. Dave foolishly believes the universe is closed.
Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.
