To all planetary scientists who work with challenging or precious samples. We are currently seeking abstract submissions for session 6h - Meeting Technical Challenges of Current and Future Planetary Science and Cosmochemistry at Goldschmidt 2024, 18-23 August, in Chicago, Illinois. Keynote speaker: Michelle Thompson, Purdue University Session description: The last several years have seen a rapid demand for new techniques for handling and analysis of precious samples from extraterrestrial sources. These include successful return samples from comets, asteroids, and other planetary bodies by the Stardust, Genesis, Hayabusa 1&2 and OSIRIS-REx missions, newly-released and cryogenically-stored Apollo-era soils, and the future return of Martian and lunar samples. Many of these samples are in the form of small sized regolith particles and are thus resolution- and/or atom-limited, requiring new multi-analytical approaches to gain maximum scientific output from a minimal sample volume. Consideration must also be taken to preserve the pristine nature of the samples during storage, preparation, and analysis, minimizing exposure to ambient temperatures and atmosphere. In the case of Martian sample return, planetary protection regulations require initial treatment in a biosafety level 4 (BSL-4) environment, and incorporating robust analytical capabilities into such an environment prior to sample sterilization poses a significant technical challenge in the coming years. Furthermore, researchers are finding new applications for machine learning, computationally-intensive statistical analysis methods, and other software approaches to glean results from ever-growing and correlated, multi-instrumental datasets. This session will bring together new research and technical advances related to planetary science and cosmochemistry, highlighting the particular challenges posed by these extraterrestrial samples. Abstracts are due by March 29.
