MoonDB was an online accessible, quality-controlled data system that synthesized analytical data acquired on lunar samples to make them accessible in a single data product so they can be mined and integrated into digital research data infrastructure, thus augmenting their value for future science.

MoonDB preserved and restored lunar sample data that have been scattered across the scientific literature, in online PDF documents, and in private files, but it also serves as a home for new data generated on samples allocated to a global community of researchers by the Curation and Analysis Planning Team for Extraterrestrial Materials (CAPTEM), so that these data can be made openly accessible in compliance with US federal mandates for open access to research results while being seamlessly integrated with the historical data.

The lunar sample data from MoonDB are now part of the Astromaterials Data System via the AstroMat Search application. To access the original MoonDB search interface, see and the MoonDB API at
