Brief Description
Comets are unique primitive objects that play a special role in our quest to understand the origin and early history of the solar system. The objective of this session is to obtain a better understanding of the comets in many respects such as the chemical composition and abundances of the various elements, the physical and chemical processes of comets involved in formation from the interstellar dust and evolution to planetesimals and the nature of solar wind interaction with the cometary coma. This session will specially focus on the topics which can relate the current knowledge on comets from the ground observations, the laboratory experiments and the previous space missions to the experiments conducted by the future space missions such as Stardust and Rosetta. This session is going to be held in right time just after apparition of two great comets in early 2004.
