The James Webb Space Telescope (JWST) was endorsed in the 2000 Astronomy Decadal report as its top-ranked project; JWST was widely recognized as the next Great Observatory to replace the Hubble Space Telescope (HST). The Decadal recommendation was accepted by NASA and work on the Observatory began soon thereafter with support from Congress and the Office of Management and Budget (OMB). JWST had a prolonged technology development period following the selection of the prime contractor in 2002. It is difficult to predict how long it will take to develop a new technology, and during the period from 2002 to 2008, JWST struggled with several cutting-edge developments. These developments took longer and consequently cost more than forecast during Formulation, prompting NASA Administrator Michael Griffin to note that JWST had been underfunded during that period. Nonetheless, enthusiasm for the scientific potential of the Observatory, building upon the continuing scientific discoveries of Hubble, has led to great interest in completing and launching JWST. The recent 2010 Astronomy Decadal Survey, for instance, reaffirmed the scientific importance of JWST. As Senator Barbara Mikulski noted in her letter requesting an independent review of JWST, 'The James Webb Space Telescope will be the most scientifically powerful telescope NASA has ever built-100 times more powerful than the Hubble, which has already rewritten our textbooks.' The required technology challenges have successfully been met and JWST is poised to deliver on that promise. As the panel set up by NASA in response to the request from Senator Mikulski, the ICRP recognizes the widespread support for this mission, but also the frustration that its continual budget problems have engendered. Given the importance for NASA to deliver this major space project at the cutting edge of technology, the Panel took an objective, thorough look at this Project and how it was managed with the goal of providing recommendations that will lead to a successful launch for JWST at the smallest additional investment by the nation.
