The Next Generation Space Telescope (NGST) Image Processing Group is developing scalable cosmic ray rejection and data compression algorithms for parallel processors as part of NASA's Remote Exploration and Experimentation (REE) Project. The primary intention of the REE project is to use commercial-off-the shelf (COTS) technology to develop scalable, low-power, fault tolerant, high performance computers in space. NGST is one of the applications selected to demonstrate the benefit of having on-board supercomputing power. Real-time cosmic ray rejection would enable us to reduce the downlink data volume by as much as two orders of magnitude by combining multiple read-outs on the spacecraft rather than downlinking them separately. The combined read-outs can be further reduced in size by applying lossy and/or lossless data compression algorithms.
This work is funded by NASA's REE project, managed by JPL.
