NASA's Marshall Space Flight Center (MSFC) maintains an active research program toward the development of high-resolution, lightweight, grazing-incidence x-ray optics to serve the needs of future x-ray astronomy missions such as Lynx. MSFC development efforts include both direct fabrication (diamond turning and deterministic computer-controlled polishing) of mirror shells and replication of mirror shells (from figured, polished mandrels). Both techniques produce full-circumference monolithic (primary + secondary) shells that share the advantages of inherent stability, ease of assembly, and low production cost. However, to achieve high-angular resolution, MSFC is exploring significant technology advances needed to control sources of figure error including fabrication- and coating-induced stresses and mounting-induced distortions.
美国国家航空航天局马歇尔太空飞行中心（MSFC）正在开展一项积极的研究计划，致力于开发高分辨率、轻质掠入射X射线光学器件，以满足未来诸如“天猫座”等X射线天文学任务的需求。MSFC的研发工作包括镜筒的直接制造（金刚石车削和确定性计算机控制抛光）以及镜筒的复制（从有形状的抛光芯轴复制）。这两种技术都能制造出全圆周整体式（主镜+副镜）镜筒，具有固有稳定性、易于组装和生产成本低等优点。然而，为了实现高角分辨率，MSFC正在探索控制形状误差源所需的重大技术进步，这些误差源包括制造和涂层引起的应力以及安装引起的变形。
