OSIRIS-REx
NASA’s OSIRIS-REx mission returned the first U.S. sample from an asteroid, Bennu, in September 2023. These materials are currently being studied by the OSIRIS-REx Sample Analysis Team to uncover new insights into the formation and evolution of our solar system.
Astromat was designated the NASA repository for the analytical data produced from these returned samples. Since 2002, our team has collaborated closely with the OSIRIS-REx scientists to build an automated pipeline for depositing lab-generated data directly into our archive.
The data is made available through the Astromaterials Data Archive and include a wide range of geochemical and physical measurements, from elemental abundances and isotopic compositions to mineralogy, spectroscopy, and imaging datasets. These records are fully searchable and downloadable, with metadata structured to support reuse and cross-sample comparisons.
