The Astromaterials Acquisition and Curation Office (AACO) at NASA Johnson Space Center (NASA-JSC) has initiated the development of an astromaterials data system (AstroDB) by the EarthChem group at the Lamont-Doherty Earth Observatory. AstroDB will extend the content and functionality of the existing MoonDB data system to provide easy access to a comprehensive synthesis of analytical data acquired on astromaterial samples curated at the JSC. This splinter meeting aims to inform the community about development plans and timelines and system features, and to invite the community to engage in the project.
