The James Webb Space Telescope (JWST) is the scientific successor to the Hubble Space Telescope. It is a cryogenic
infrared space observatory with a 25 m2 aperture (6 m class) telescope that will achieve diffraction limited angular
resolution at a wavelength of 2 um. The science instrument payload includes three passively cooled near-infrared
instruments providing broad- and narrow-band imagery, coronography, as well as multi-object and integral-field
spectroscopy over the 0.6 < λ < 5.0 um spectrum. An actively cooled mid-infrared instrument provides broad-band
imagery, coronography, and integral-field spectroscopy over the 5.0 < λ < 29 um spectrum. The JWST is being
developed by NASA, in partnership with the European and Canadian Space Agencies, as a general user facility with
science observations to be proposed by the international astronomical community in a manner similar to the Hubble
Space Telescope. Technology development and mission design are complete. Construction, integration and verification
testing is underway in all areas of the program. The JWST is on schedule for launch during 2018.
