Dear Colleagues We would like to bring your attention to our session, *T16-S1: **Mineral physics and planetology: a journey across the universe* of the 3rd European Mineralogical Conference, that will be held online from *August 29th until September 2nd, 2021*. https://emc2020.ptmin.eu/themes/t17-planetary-materials-and-processes/t17-s1-mineral-physics-and-planetology-a-journey-across-the-universe/ Remote sensing data from recent spatial missions as well as more and more accurate observations on small and large bodies inside and outsite the solar system, provide information on their compositions and inner structure, atmospheres and the possible existence of habitable places beyond the Earth Mineral physics studies, such as laboratory experiments and theoretical simulations on minerals and rocks, at extreme conditions such as high pressures o stresses, variable temperatures, different redox states provide a key to interpret remote sensing data and to argue the composition, dynamic and evolution of the planetary bodies. This session is open for contributions from experimental and computational mineralogists, petrologists, geophysicists, geochemists, and planetologists on various mineral physics cross-disciplinal topics related to studies of Earth, solar system bodies and exoplanets. Abstract submission is now open. Please consider to join us online! Abstract submission deadline: *May 31st*.
