Abstract

The James Webb Space Telescope (JWST) is a large space based astronomical telescope that will operate at cryogenic temperatures. The telescope by virtue of its size must be stowed in an inoperable configuration for launch and remotely reconfigured in space to meet the operational requirements using active Wave Front Sensing and Control (WFSC). This paper will report on the optical budgeting process used to manage the performance of the active system. The current status of the design and verification of the optical hardware, the WFSC processes, and the total system verification modeling will be presented. More detailed discussions of the system verification by analysis will be presented in separate accompanying papers.
