The Astrolabe Project is working with CyVerse cyberinfrastructure to provide an easy-to-use, reliable and long-lived environment for processing, storage and visualization of valuable scientific data that are not managed as part of existing missions and trusted repositories. Particular emphasis is given to individual researchers and research groups with older, orphaned datasets that can add context to new research enterprises.
