Constellation-X任务将解决NASA超越爱因斯坦计划的核心问题，使用高通量X射线光谱来测量靠近黑洞事件视界的强引力的影响，研究星系团的形成和演化，以精确确定宇宙学参数值，测量暖热星系间介质的性质，并确定中子星的状态方程。实现这些科学目标需要高分辨率光谱的灵敏度比当前 X 射线天文台提高约 100 倍。本文简要介绍了Constellation-X任务，总结了其有效面积和光谱分辨率等基本性能参数，并给出了该任务的总体更新。介绍了与单个 Atlas-V 551 运载火箭兼容的更新任务配置的详细信息。
The Constellation-X mission will address questions central to the NASA Beyond Einstein Program, using high throughput X-ray spectroscopy to measure the effects of strong gravity close to the event horizon of black holes, study the formation and evolution of clusters of galaxies to precisely determine cosmological parameter values, measure the properties of the Warm-Hot Intergalactic Medium, and determine the equation of state of neutron stars. Achieving these science goals requires a factor of ~100 increase in sensitivity for high resolution spectroscopy over current X-ray observatories. This paper briefly describes the Constellation-X mission, summarizes its basic performance parameters such as effective area and spectral resolution, and gives a general update on the mission. The details of the updated mission configuration, compatible with a single Atlas-V 551 launch vehicle, are presented.
