The Astromaterials Data System (Astromat) serves as NASA’s official archive for laboratory analyses of returned samples from planetary missions and meteorites, providing a critical platform for the curation, publication, long-term preservation, and access to astromaterials analytical data. Astromat is dedicated to advancing scientific discovery by aligning its services with the FAIR Principles—ensuring that mission and research data are Findable, Accessible, Interoperable, and Reusable. By enabling the discovery and reuse of laboratory analytical data, Astromat maximizes the value and impact of unique astromaterials samples, supporting science, education, and society at large.
Astromat’s membership in the World Data System reflects a strong alignment of mission and values. Both organizations are committed to fostering open data sharing, transparency, and global collaboration. Through WDS, Astromat will further facilitate the integration of astromaterials sample data across the international research community, support data attribution and research verification, and contribute to best practices in trustworthy data stewardship. This partnership strengthens a culture of openness in planetary sciences and enhances the reach and utility of astromaterials data worldwide. They joined WDS as a Regular member in October 2025.
