Important Update News

The RRUFF Project (rruff.info) is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional.

We are grateful to NASA for the funding of this effort.
