Role of optical storage technology for NASA's image storage and retrieval systems
Charles D. Benjamin · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1990
The National Aeronautics and Space Administration (NASA) is proceeding with an evolutionary approach to creating integrated muIti discipline image management systems. A goal of this development is an integrated Astrophysics Data System (ADS). The system will allow astrophysics research teams to' correlate spectral images from multiple research satellites. The ADS is the first large scale integrated research data system planned at NASA. The Earth Observing System Data and Information System (EosDlS) will create a similar system for earth sciences research. These two programs will store and retrieve more than 1 0 terabytes of satellite image data per day. Ford Aerospace is actively involved in the design and development of both the ADS and EosDlS. This paper reviews the role of optical storage technology in supporting these image storage and retrieval systems. It explores system limits based upon the current state of optical storage technology. Also discussed, are those advances in optical storage technology that could increase the role for optical storage in NASA's image management systems.
