Despite years of investigation, the solid, quasi-permanent component of comets, the nucleus, remains largely a mystery. Its composition and thermal properties determine the evolution of the more familiar and often spectacular cometary features, the coma and the tail. Under some circumstances, the (≈200 K) nucleus may be obscured by a dust cloud of much higher temperature. It appears that the most appropriate technology for the investigation of the surface and subsurface layers of the nucleus is millimeter- ...
