“天文-C”卫星继“天鹅”和“天马”两颗探测X线天文卫星之后,“天文-C”卫星装载了更高性能的X线望远镜,以研究银河系以外的X线天体。这架望远镜由宇宙科学研究所和英国的莱斯特大学共同研制,比“天马”卫星的望远镜口径几乎大一位数。“天文-C”卫星是一颗重400公斤的三轴稳定卫星。Exos_D探测卫星为了研究引起极光带电粒子的加速机理,这颗卫星装载电场、磁场、等离子波动及 Astronomy-C Satellite Following the two X-ray astronomy satellites, Swan and Pegasus, the Astronomy-C satellite is loaded with higher-performance X-ray telescopes to study X-ray objects beyond the Milky Way. The telescope, co-developed by the Institute of Cosmic Sciences and the University of Leicester in the United Kingdom, is almost one-digit larger than the telescopes of the Pegasus satellite. The Astronomical-C satellite is a tri-axis stable satellite weighing 400 kg. Exos_D satellites In order to study the accelerating mechanism that causes charged charged particles in the aurora, the satellite is loaded with electric, magnetic, and plasma fluctuations
