Development of Constellation-X Optics Technologies at MSFC

Abstract

One of the major technological challenges for the Constellation X-ray Mission is the development of light-weight, high-resolution, grazing-incidence optics. NASA's Marshall Space Flight Center is developing and evaluating candidate technologies, based upon full-shell replication off precision mandrels. Here we report on recent progress in meeting the weight and imaging-performance requirements, using very thin, high- strength electroformed nickel alloys, In addition, we briefly describe MSFC's optics fabrication, metrology, and x-ray test facilities.
