Data Repository Systems Overview

The Data Repository Systems (DRS) Group develops and maintains archival data management systems that capture, curate, preserve, and disseminate data from NASA missions, projects, and research activities both for NASA internal usage, and for external use by other government agencies and the greater scientific community. The group has created repositories for Near Earth Objects (NEOs), astrobiology data, and life sciences and space biology data, as well as for the Human Research and Space Biology programs’ institutional biobanks at Ames Research Center and Johnson Space Center. The group is experienced in handling specific NASA requirements related to secure management of export-controlled information and sensitive personal data, including medical data.
