The James Webb Space Telescope (JWST)

Abstract

The James Webb Space Telescope is a 6.5 m, infrared space telescope designed to be launched in 2013 aboard an Ariane 5. The JWST program is a cooperative program with the Goddard Space Flight Center (GSFC) managing the project for NASA. The prime contractor for JWST is Northrop Grumman Space Technology (NGST). JWST’s international partners are the European Space Agency (ESA) and the Canadian Space Agency (CSA). JWST will address four major science themes: end of the dark ages: first light and reionization; the assembly of galaxies, the birth of stars and protoplanetary systems; and the formation of planetary systems and the origins of life. We discuss the design of the observatory and review recent progress on the JWST program.
