Concluding Remarks on the Planetary Rings Conference

In the past five years ring systems have been discovered around Uranus and Jupiter and a wealth of new data acquired about Saturn's rings. This vigorous observational program has been accompanied by renewed theoretical interest in ring systems. Although all of these topics have been addressed in papers at this first conference on planetary rings, these concluding remarks are focused on some of the key aspects of Saturn's rings about which more needs to be understood through further data analysis, calculations, and observations.
