The Webb Space Telescope - An Engineering Marvel Story

This presentation will provide an overview of the James Webb Space Telescope (JWST) and its engineering development process. JWST has succeeded the Hubble Space Telescope in our quest for the first galaxies formed out of the darkness of the early universe. Since its launch in December 2021, JWST has helped us understand how these galaxies evolved over billions of years, how stars and planetary systems form, what exoplanets look like and if they can harbor life. JWST uses a ~6.5-m-diameter primary mirror to collect infrared light, which is sent to four scientific instruments. It operates at the second Sun-Earth Lagrange point and has a five-layer sunshield to be able to operate at cryogenic temperatures. JWST is an international effort of NASA and the European and Canadian Space Agencies.
