Scope 
Recent progress of astronomical observations, laboratory experiments, solar-system exploration, and theoretical work makes it possible to understand the origin and evolution of materials (dust and gas) in space, and has led to developments in the fields such as astrochemistry and astromineralogy. It is thus important to link further planetary material science and astronomy from a chemical and mineralogical perspective to understand the role of dust and gas in the evolution of galaxies, stars, and planetary systems, comprehensively. Infrared/sub-mm/mm observations with current/future large satellites/telescopes are suitable for the study of gas and dust, and are expected to bring a new frontier of gas/dust study. In this session, based on the latest results on astronomical observations (including ALMA, JWST, etc.), experiments, and theoretical studies on materials in space, we discuss the next steps in science for materials in space to maximize the outcome of the observations with future satellites and telescopes.
