Abstract

This paper is an overview of the Next Generation X-ray Optics effort at NASA’s Goddard Space Flight Center. The objective of the NGXO effort is to develop and mature an X-ray mirror technology that is capable of building and delivering a mirror assembly for flagship missions like Lynx and Probe missions like AXIS, which have been recommended by Astro2020 for implementation in the coming decade(s). The NGXO work encompasses all elements that compose a complete process to design, build, test, and deliver a complete mirror assembly, including optical design, mirror segment fabrication, coating, alignment and bonding to make mirror modules, integration of mirror modules into meta-shells, and integration of meta-shells into a mirror assembly. In addition, the NGXO team also adopts the latest mass-production techniques to ensure that building such a mirror assembly can also meet programmatic, such as schedule and cost, requirements of future missions like Lynx and AXIS.
