The CNME Project, a National Curation Center for Extraterrestrial Samples in France
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.
