在这个多信使天文学时代，所有的观测探测器都在提高它们的灵敏度和整体性能。聚焦相对论性宇宙和宇宙演化（FORCE）使命是日本宇宙航空研究开发机构/美国航天局合作的产物，与以前的任何硬X射线飞行任务相比，它在硬X射线波段（E > 10 keV）的灵敏度将提高10倍，并同时提供软X射线覆盖。FORCE计划在21世纪30年代初发射，为欧空局的旗舰使命雅典娜提供完美的硬X射线补充。FORCE将是发现遮蔽/隐藏黑洞和研究我们宇宙中高能粒子加速的最强大的X射线探测器，并将解决宇宙中相对论过程如何实现以及这些过程如何影响宇宙演化。FORCE将在1-79 keV范围内运行，配备了两对相同的超级反射镜和宽带X射线成像仪。反射镜和成像器通过一个高机械刚度的可扩展光学工作台连接，该光学工作台带有焦距为12 m的对准监控系统。采用多层膜结构的轻质硅反射镜在宽带通范围内实现了半焦度直径< 15 "的高角分辨率。该成像器是一个全新的SOI-CMOS硅像素探测器和CdTe探测器的混合体，分别负责较软和较硬的能带。FORCE将以其宽带X射线灵敏度在2030年代的多信使天文学中发挥重要作用。
In this multi-messenger astronomy era, all the observational probes are improving their sensitivities and overall performance. The Focusing on Relativistic universe and Cosmic Evolution (FORCE) mission, the product of a JAXA/NASA collaboration, will reach a 10 times higher sensitivity in the hard X-ray band (E > 10 keV) in comparison with any previous hard x-ray missions, and provide simultaneous soft x-ray coverage. FORCE aims to be launched in the early 2030s, providing a perfect hard x-ray complement to the ESA flagship mission Athena. FORCE will be the most powerful x-ray probe for discovering obscured/hidden black holes and studying high energy particle acceleration in our Universe and will address how relativistic processes in the universe are realized and how these affect cosmic evolution. FORCE, which will operate over 1–79 keV, is equipped with two identical pairs of supermirrors and wideband x-ray imagers. The mirror and imager are connected by a high mechanical stiffness extensible optical bench with alignment monitor systems with a focal length of 12 m. A light-weight silicon mirror with multi-layer coating realizes a high angular resolution of < 15′′ in half-power diameter in the broad bandpass. The imager is a hybrid of a brand-new SOI-CMOS silicon-pixel detector and a CdTe detector responsible for the softer and harder energy bands, respectively. FORCE will play an essential role in the multi-messenger astronomy in the 2030s with its broadband x-ray sensitivity.
