Metbase Merged With Astromat

After 30 years, and many changes, MetBase just made its last, and biggest change ever: it merged with NASA’s Astromaterials Data System (Astromat). We believe it is in the best interest of the meteoriticists and cosmochemistry community to have only one webpage to access all of the astromaterials data, which is now the case in a great and sustainable way with our colleagues from Astromaterials.

We just published everything about this merger in an open access MAPS article, which you can find here:

Hezel DC, Lehnert KA, Elangovan P, Ji P, Mays J, Koblitz J (2025) The MetBase database has been merged into Astromat. Meteoritics & Planetary Science 60:143-148. [https://doi.org/10.1111/maps.14293]

MetBase and the current MetBase webpage will be discontinued soon, however, there are some plans for a new data access system from the metbase.org webpage. Stay tuned for this late in 2025.
