The building blocks for JWST Iamp;amp;T to operations: from simulator to flight units

摘要

The James Webb Space Telescope (JWST) Project has an extended integration and test (I&T) phase due to longprocurement and development times of various components as well as recent launch delays. The JWST GroundSegment and Operations group has developed a roadmap of the various ground and flight elements and their use in thevarious JWST I&T test programs. The JWST Project's building block approach to the eventual operational systems,while not new, is complex and challenging; a large-scale mission like JWST involves international partners, manyvendors across the United States, and competing needs for the same systems. One of the challenges is resourcebalancing so simulators and flight products for various elements congeal into integrated systems used for I&T and flightoperations activities.This building block approach to an incremental buildup provides for early problem identification with simulators andexercises the flight operations systems, products, and interfaces during the JWST I&T test programs. The JWST Projecthas completed some early I&T with the simulators, engineering models and some components of the operational groundsystem. The JWST Project is testing the various flight units as they are delivered and will continue to do so for theentire flight and operational system. The JWST Project has already and will continue to reap the value of the buildingblock approach on the road to launch and flight operations.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
