The Cosmic X-Ray Background NanoSat (CXBN): Measuring the Cosmic X-Ray Background using the CubeSat Form Factor

摘要: The CXBN mission goal is to significantly increase the Cosmic X-Ray Background measurement precision in 30-50 keV range. addresses a fundamental science question central our understanding of structure, origin, and evolution universe by potentially lending insight into high energy background radiation. spacecraft will map Extragalactic Diffuse (DXRB) with new Cadmium Zinc Telluride (CZT) detector. DXRB pose powerful tool for early window far-away universe. objectives were condensed novel concept characterized sun-pointing, spinning LEO moderate inclination. Launch trajectories allow four nominal passes per day over primary Earth station at Morehead State University (Morehead, KY). requirements fortunately adoption economical CubeSat form factor. major subsystems comprising satellite are — having been developed team. Innovative systems include power distribution, command data handling, attitude determination control systems.
