The first indication that interplanetary dust might interact with planetary magnetospheres, and yield observable consequences, came from analysis of the data from the HE0S dust detector in 1978/79. It was suggested that electrostatic breakup of fluffy interplanetary aggregates possibly of cometary origin were responsible for the large increase in micron-sized particle fluxes within ~10 Earth radii.

The Voyager missions to the ringed planets have since provided the basic observations for a large number of phenomena concerned with dust-magnetosphere interactions. Until then, planetary rings were regarded as purely gravitational phenomena, whereas we now know that many micron-sized particles exist in the rings (produced by e.g. grinding and impacts) and that these also experience electromagnetic and plasma drag forces. Of particular interest in recent studies have been the basic physical processes in "dusty" plasmas, the application to dust particles ejected from Io's volcanoes, the formation of Jupiter's tenuous ring and halo, in Saturn's magnetosphere the dynamics and evolution of the E-ring, the spokes and the possible rnagneto-gravitational effects on narrow ringlets.

This meeting is the first attempt to coordinate under a common heading of "Dust-Magnetosphere Interactions" a number of different disciplines:

The aim of the meeting was to bring the different communities together, to determine the current status of the research being done in the various fields and to ascertain the role played by solids in planetary magnetospheres either as sources and sinks of plasma, dynamically, mechanically etc. and finally to highlight the physics of "dusty" plasmas, which is very different from ordinary plasma physics and from gravitational dynamics alone.

My Co-organizer, Chris Russell, and I enjoyed the meeting, in spite of the fact that the New York rain was responsible for a great deal of last minute rescheduling and activity. We wish to take this opportunity to thank all the contributors and the participants, who helped to make this meeting such a success.
