Paper Abstract

Ball Aerospace and Technologies Corp. (BATC) is developing a Fine Steering Mirror (FSM) for the James Webb Space Telescope (JWST). This high reliability FSM is designed to provide line-of-sight steering in two orthogonal axes as part of the Aft Optical System (AOS) of a large telescope that operates at the L2 Lagrange point. This paper presents the mechanical design of the mechanism which satisfies stringent requirements for operation in vacuum and cryogenic environments. Also given is a status of the flight hardware development and early results of cryogenic testing.
