摘要
欧几里得是欧洲空间局（ESA）的一项天基光学/近红外巡天任务，旨在通过观测宇宙几何结构及宇宙学时间尺度上的结构形成来研究暗能量、暗物质和引力的本质。欧几里得将使用两种探测暗物质与能量特征的探针：弱引力透镜，需要测量遥远星系的形状和测光红移；以及星系成团，基于通过光谱红移测量星系的三维分布。该任务计划于2020年发射，设计标称巡天运行6年。欧几里得航天器由服务舱和载荷舱组成。服务舱包含全部常规航天器分系统、仪器温电子单元、遮阳板和太阳电池阵。特别是，服务舱提供科学目标所需的极具挑战性的指向精度。载荷舱由一台1.2米三镜Korsch型望远镜和两台仪器组成：可见光成像仪和近红外分光光度计，两者覆盖一个大的共用视场，能够巡天超过整个天空的35%。所有传感器数据使用K波段传输下行，并由专用地面段进行科学数据处理。欧几里得数据和星表将在ESA科学数据中心向公众开放。
