Paper Abstract

The Precision Segmented Reflectors (PSR) project represents a first step toward developing the technology base needed to support future advanced astrophysics missions, especially those that operate at submillimeter wavelengths. The focus of the effort is to develop a lightweight, low cost option for building large aperture, segmented reflecting space-based telescopes. The principal driver for PSR technology is the Submillimeter Telescope program including the proposed 20 meter Large Deployable Reflector (LDR) telescope, and its precursor-survey mission which is currently in early development and definition. Four major technical areas, reflector panels and materials, structures, and figure control are under development by PSR. These technical areas are, however, generic in nature and can be applied to other future missions such as optical communications, optical interferometers, and missions requiring large diameter, segmented reflectors. In this paper, specific project objectives, approaches and significant challenges will be described. Technology development issues encountered will also be discussed. Finally, project status will be reported.
