1.1   研发背景(Background)

2011年1月,空间探测暗物质粒子纳入紫金山天文台“一三五”规划。2011年12月,暗物质粒子探测卫星正式立项启动,成为中国战略性先导科技专项空间科学专项首批四颗科学实验卫星之一。

2011-12, the DAMPE mission was officially launched. It is one of five satellite missions in the framework of the Strategic Pioneer Research Program in Space Science of the Chinese Academy of Sciences (CAS).

1.2   研制单位(Developer and Manufacturer)

悟空暗物质粒子探测卫星由中国科学院微小卫星创新研究院抓总研制,中国科学院国家空间科学中心负责卫星工程大总体及地面支撑系统工作,中国科学院紫金山天文台负责科学应用系统研制、建设、运行,西安卫星测控中心负责卫星测控系统任务。

The Wukong dark matter particle detection satellite is developed by the Institute of Microsatellite Innovation of the Chinese Academy of Sciences. The National Space Science Center of the Chinese Academy of Sciences is responsible for the overall satellite engineering and ground support system. The Zijinshan Observatory of the Chinese Academy of Sciences is responsible for the development, construction and operation of the scientific application system. Xi’an The satellite measurement and control center is responsible for satellite measurement and control system tasks.

1.3   目标任务(Satellite Mission)

通过高能量分辨和高空间分辨,观测高能电子和伽玛射线能谱和空间分布,寻找和研究暗物质粒子;通过测量TeV以上的高能电子能谱,研究宇宙线起源;通过测量宇宙线重离子能谱,研究宇宙线传播和加速机制。建造一台能量观测能段覆盖2GeV至10TeV,分辨优于1.5%(对800GeV电子和光子)的星载电磁量能器,将有望在暗物质粒子探测和宇宙线物理这两大科学难题上取得突破,同时为更好地研究伽玛射线天文学等相关重要科学问题提供一个新的平台。

The scientific objectives of Dark Matter Particle Explorer are to search for and study dark matter particles by conducting high-resolution observation of high-energy electron and gamma-ray, to study the origin of cosmic rays by observing the high energy electron and heavy nuclei above TeV, and to study the propagation and acceleration mechanism of the cosmic ray by observing high-energy gamma-ray.
