Dear colleagues, there are less than two weeks left to submit your abstracts at the **Goldschmidt Conference** (August 18-23, Chicago, USA). Please consider submitting an abstract to the exciting session **# 2b** that we are organizing this year: **2b - Deep planetary interiors: new experimental and analytical approaches** **(**<https://conf.goldschmidt.info/goldschmidt/2024/goldschmidt/2024/meetingapp.cgi/Session/6162>**)** *Experimental studies and theoretical simulations of material properties at extreme conditions are one of the few but prevailing ways that geoscientists use to understand and model the processes taking place in the most complex parts of the deep Earth and other planetary interiors. Yet more discoveries await in sight of recent technological advances in experimental designs and computing efficiency, sample preparation and synthesis methods, analytical tools as well as AI assisted data collection and processing protocols with supporting software. The science front is driven by the challenges that the high-pressure community faces in exploring the mineral physics and crystal chemistry of geomaterials at elevated pressure, temperature and stress conditions. In particular, the enhanced spatial and energy resolution of X-ray and optical techniques at large facilities and advanced laboratories encourage experiments at the ultimate instrumental limits. The resulted superior data quality derived grand access to an infinite number of mineral properties, and in combination with computational approaches, allow the full assessment of countless plausible scenarios that help describe the micro- and macroscopic processes that govern the deep planetary interiors. This session welcomes all contributions that highlight cutting-edge achievements in static and dynamic experimental methods as well as novel analytical approaches that address a variety of physical and chemical properties of minerals, and enhance our understanding of the evolution, structure and dynamics of the Earth’s interior and that of other planetary bodies.* **Confirmed Speakers:**   Thomas S.
