The James Webb Space Telescope (JWST) is NASA's flagship astrophysics mission. Currently under construction, and scheduled for launch in 2018, JWST is a cryogenic telescope with a 6.5-meter primary mirror and four science instruments offering sensitivity from 0.6 to 28.5 microns. The telescope will be diffraction limited at 2 microns, 4 microns, and 7+ microns. The instruments contain 40 imaging filters (pixel scale down to 0.032”), 8 spectroscopic modes (wide field grism, single object, IFU, multiobject), and 7 coronographs. A telescope for the astrophysics community, JWST was developed to provide cutting edge observations that will delve into the mysteries of the first objects to form in the early universe, the assembly of galaxies, the birth of stars and planetary systems, and planetary systems and the origins of life.
