任务简介
爱因斯坦探针（EP）是中国的一台宽视场X射线天文观测台，用于探测灾难性宇宙事件的高能闪光。这些事件包括潮汐瓦解事件（恒星被超大质量黑洞撕裂）、超新星以及引力波事件的高能电磁对应体。 该航天器重约1400公斤，将被发射到600公里高、低倾角的轨道。探针的仪器包括一个宽视场X射线望远镜（WXT），视场为3600平方度，采用尖端的“龙虾眼”光学技术，能够比以往更深入、更广泛地观测X射线事件；以及一个与欧洲合作开发的后续X射线望远镜（FXT），一旦WXT探测到X射线事件，FXT将立即进行后续详细观测。 爱因斯坦探针任务由NSSC管理，参与方包括中科院国家天文台（NAOC）、高能物理研究所（IHEP）、上海技术物理研究所（SITP）以及创新微卫星研究院——该航天器制造商此前曾生产过空间科学和北斗导航航天器。 欧洲空间局为任务贡献了FXT仪器的镜模块，并提供地面站和科学管理支持。FXT仪器还得到了德国马克斯·普朗克地外物理研究所的支持。
原文
The Einstein Probe (EP) is a Chinese Wide-Field X-ray astronomy observatory for detecting high energy flashes of cataclysmic cosmic events. These includes tidal disruption events (stars pulled apart by supermassive black holes), supernovae, and high-energy, electromagnetic counterparts of gravitational wave events. The spacecraft, weighing ~1400 kilograms, will be launched into a 600-kilometer-high, low-inclination orbit. The probe's instruments include a Wide-field X-ray Telescope (WXT) with a field of view of 3,600 square degrees, employing cutting-edge "lobster eye" optics to view X-ray events more deeply and widely than previously possible, and a Follow-up X-ray Telescope (FXT), developed in collaboration with Europe, that performs follow-up detailed observations as soon as WXT detects an X-ray event. The Einstein Probe mission is managed by the NSSC, with participation from the CAS's NAOC, the Institute of High Energy Physics (IHEP), the Shanghai Institute of Technical Physics (SITP), and the Innovation Academy for Microsatellites, a spacecraft manufacturer that has previously produced space science and Beidou navigation spacecraft. The European Space Agency is contributing to the mission with a mirror module for the FXT instrument, as well as ground station and science management support. The FXT instrument is also supported by Germany's Max Planck Institute for Extraterrestrial Physics.
