OSIRIS-REx
NASA’s OSIRIS-REx mission returned the first sample from asteroid, Bennu, in September 2023. These asteroid samples 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 as the NASA repository for the analytical data produced from these returned samples. Since 2022, the Astromat team has collaborated closely with OSIRIS-REx scientists and data managers to build an automated pipeline for depositing lab-generated data from Bennu samples directly from the SAMIS (Sample Analysis Micro-Infromation System) into the Astromat Data Archive.
The OSIRIS-REx data is made available through the Astromaterials Data Archive and includes a wide range of cosmochemical 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.
