人类探索太空的脚步从未停歇。自1957年第一颗人造卫星上天之后，空间技术的发展催生了人类认知宇 宙的"大爆发"时代。人类不但发射了卫星、宇宙飞船、空间站，还登上了月球。航天科技不仅使人们的 日常生活发生了翻天覆地的变化，也催生了空间科学，极大地拓展了人类认知的边界，带来了范艾伦辐 射带、日冕物质抛射、X射线源、γ射线暴等一系列突破性的科学发现。 2011年，中国科学院空间科学先导专项正式立项，开启了我国科学卫星系列的新时代。专项一期包含4 颗卫星，其中之一就是中国科学院紫金山天文台常进研究员基于其自主数据处理方法而提出的暗物质粒 子探测卫星。天文学家观测发现，宇宙中存在着大量暗物质，但并不清楚它们究竟是什么。暗物质粒子 探测卫星的主要科学目标，就是在电子宇宙线和γ射线中寻找暗物质粒子的信号。 暗物质粒子探测卫星工程于2011年12月正式立项，我被任命为暗物质粒子探测卫星工程的副总指挥，在 4年里见证了这颗卫星从原理样机到在天遨游的整个研制历程。立项之初，研发经验和人手奇缺，常进 所在的中国科学院紫金山天文台研发团队成员尚不足10人，绝大部分都是新手。载荷参研单位中，除了 中国科学院高能物理研究所有少数同志具备 ...
