计划于2021年底发射的成像X射线偏振探测器(IXPE)是一项小型探测器任务，旨在开辟一个新的研究窗口--X射线偏振测量。IXPE天文台有3个相同的望远镜，每个望远镜都由一个反射镜组件组成，在其焦点上有一个偏振敏感成像X射线探测器。在轨道上展开的延伸波束提供了必要的4米焦距。有效载荷位于一个三轴稳定的航天器的顶部，该航天器提供动力、姿态确定和控制、指挥以及地面遥测等功能。在其为期两年的基线任务期间，IXPE将对多种类别的X射线源样品进行精密偏振测量，并对选定的目标进行后续观测。IXPE是NASA和意大利航天局(ASI)之间的合作伙伴关系。
Scheduled to launch in late 2021 the Imaging X-ray Polarimetry Explorer (IXPE) is a Small Explorer Mission designed to open up a new window of investigation -- X-ray polarimetry. The IXPE observatory features 3 identical telescope each consisting of a mirror module assembly with a polarization-sensitive imaging x-ray detector at its focus. An extending beam, deployed on orbit provides the necessary 4 m focal length. The payload sits atop a 3-axis stabilized spacecraft which among other things provides power, attitude determination and control, commanding, and telemetry to the ground. During its 2-year baseline mission, IXPE will conduct precise polarimetry for samples of multiple categories of x-ray sources, with follow-on observations of selected targets. IXPE is a partnership between NASA and the Italian Space Agency (ASI).
