As NASA's next major space X-ray observatory, the Constellation-X mission (Bookbinder et al. 2008)
requires mirror assemblies with unprecedented characteristics that cannot be provided by existing optical
technologies. In the past several years, the project has supported a vigorous mirror technology
development program. This program includes the fabrication of lightweight mirror segments by slumping
commercially available thin glass sheets, the support and mounting of these thin mirror segments for
accurate metrology, the mounting and attachment of these mirror segments for the purpose of X-ray tests,
and development of methods for aligning and integrating these mirror segments into mirror assemblies.
This paper describes our efforts and developments in these areas.
