THEMISS is a project funded by the European Research Council (ERC Starting Grant 2018). It explores the long-lasting effects of thermally-induced processing on icy objects, both in the Solar System reservoirs (Oort Cloud, Kuiper Belt, Main Belt), and once they become active as comets. Goals include understanding where the most pristine material in the Solar System may be found, or which comet characteristics may be the most relevant to constraining the origins of the Solar System.
