Small sizes of individual particles and exceedingly low spatial density are formidable problems which greatly impeded progress in the dust field during the previous decade. The major experimental problems which prevented reliable measurements appear finally to have been solved and the entire dust field has seen dramatic progress over the past four years. Major accomplishments were reliable impact and zodiacal light measurements over the range of solar distance from 0.3 AU to 5 AU and successful collection of micrometeorites from the stratosphere which has provided hundreds of proven interplanetary particles for laboratory studies. Interest in dust has grown because of the increasing realization that the solar system dust cloud is an astrophysical site where grain processes such as radiation pressure, rotational bursting, thermal alteration, ion implantation, sputtering, and magnetic effects can be studied in‐situ.
