AB: Dawn is a NASA Discovery mission that will orbit the asteroids Vesta and Ceres, following its launch in the summer of 2006. Despite the fact that the Dawn Science Team is distributed across the globe, it must live within the cost-cap constraints imposed on all Discovery missions. One of the many challenges of working within this environment is the development of effective data management, analysis, and archive systems. Even though all NASA missions face these same problems, NASA neither provides an off-the-shelf multi-mission solution nor does it provide a software toolkit to assist new missions with the development of mission specific solutions. The Dawn Science Center approach to this lack of institutional support has been to look to other NASA projects, primarily the Planetary Data System, for tools that can be easily adapted to meet the Dawn requirements. All NASA planetary missions must archive their data sets with the PDS. Building the Dawn internal data management system on the tools and standards of the PDS will facilitate the data archive process and reduce the overall cost to the mission. DITDOS 3 (Distributed Inventory Tracking and Data Ordering System), which is available from the Planetary Plasma Interactions (PPI) Node of the PDS, is a tool that provides a data management solution with web interface capabilities. DITDOS 3 allows developers to generate a searchable file system database containing metadata extracted from PDS labels. Users extract files (data) from the system by constructing queries against the database. Similarly, users upload data into the system by providing the necessary metadata to populate the database and construct PDS labels. Dawn is adapting the underlying DITDOS 3 database to support its mission specific needs. However, not all of the functions required by a science center can be supported with existing PDS technology. For example, while PDS labels are well suited to describing archival data, they have not been designed to handle many of the files missions need to manage (sequence products, timelines, schedules, etc.). Dawn is addressing these metadata deficiencies through the use of a local data dictionary. In this paper, we describe the Dawn Science Database (DSDb) architecture and functionality, the DITDOS 3 adaptations required to support the DSDb, and the Dawn specific enhancements to the PDS data dictionary.
