			| Scope | 
			
			We have made great progress in the astrophysical observation of 
			protoplanetary disk, in laboratory simulation experiments, and in 
			the analyses of meteoritic material, IDPs and samples returned from 
			a comet and solar wind. We discuss the nature of protoplanetary 
			dusts, dynamical evolution, and problems that obscure our 
			understanding of dust origin, composition and evolution in such 
			systems  |
