Résumé

The National Center for Extraterrestrial Materials (CNME) will reside within the renowned Geology and Mineralogy Gallery of the National Natural History Museum (MNHN) in Paris. A key objective of CNME will be to ensure the long-term curation of a fraction of samples from the Martian moon Phobos, spearheaded by the MMX JAXA-led mission. The MNHN meteorite collection is actively used for cosmochemistry research projects and constantly grows with new additions every year. nstrumentation in CNME will consist of a dedicated suite of instruments, to achieve initial characterization and cataloguing of samples with sizes ranging from a few μm up to cm-scales, including optical microscopy, weighing, magnetic susceptibility measurements, scanning electron microscopy, XRD, Raman and infrared (IR) micro-spectroscopy with a dedicated suite of instruments, to achieve initial characterization and cataloguing of samples. The CNME team and collaborators will gather expertise from curation to samples handling (micromanipulation, fragmentation…), first-order characterization by non-invasive and non-destructive techniques and dedicated sample preparation (e.g., thin and ultra-thin sections, polished sections, …) in clean-room environments.
