Paper Abstract

A test program has been implemented to evaluate candidate thin film materials for the sun-facing layer of the Next Generation Space Telescope (NGST) sunshield. Various polymers are being tested to determine if any can survive the radiation environment of the proposed NGST orbit (the second Sun-Earth lagrangian point or L2). This testing will characterize the mechanical and thermal properties before and after exposure to a simulated NGST sunshield environment. In addition, because the sunshield will be folded and stowed before launch, the candidate materials will be folded, stowed and unfolded (deployed) to determine if they can survive this type of handling and storage. Based on the results of this testing, candidates will be down selected for further development and testing. Future development will include the addition of optical coatings, rip-stop for tear resistance, and seaming techniques.
