Systems Engineering of the James Webb Space Telescope


Abstract

  • The James Webb Space Telescope (JWST) will be NASA's successor mission to the Hubble Space Telescope. The JWST telescope will have an aperture greater than 6 meters in diameter, and along with its compliment of science instruments must be cooled to cryogenic temperatures below 40K. The observatory will be operated at the Sun-Earth L2 point to keep thermal sources such as the Sun and Earth in the same general direction so that the payload can be shaded from their radiation by a large deployable sunshield. This presentation will give an overview of the JWST system and describe some of the more unique systems engineering challenges of this "first of its kind" mission. The presentation will also describe some of the systems engineering techniques used by the team to address these challenges to achieve launch readiness in 2018.
