Overview of the James Webb Space Telescope

The James Webb Space Telescope (JWST) is ulxve uperk/rc (6.5 meter), cryogenic space telescope with a suite of near and mid-infrared instruments covering the wavelength range of 0.6 prnio 28 pn). JWS7 s primaryacicoce goal is k) detect and characterize the first galaxies. U will also study the uascrob|y of galaxies, uiur bzcrou1ion, and the formation of evolution of planetary systems. Recent progress in hardware development for the observatory will he presented, including a discussion of the status of JWST's optical system and Beryllium mirror fabrication, progress with sunshield prototypes, and the integration and test configuration. We also review the expected scientific performance of the observatory for observations of exosolar planets by means of transit imaging and spectroscopy. We will review the science goals, the capabilities of each science instrument, and the design and operation of the telescope.
