The James Webb Space Telescope (JWST), scheduled for launch in 2018, is expected to show us the most distant galaxies that formed in the early life of the universe. To do this, it has light gathering capability unprecedented in a space telescope—its 6.5-meter-diameter mirror has more than six times the light-collecting area of Hubble’s mirror. Also, it is designed to “see” mainly infrared radiation so it can detect the red-shifted radiation of early stars and make out stars and planets that are hidden from visible-light telescopes by clouds of gas and dust. The prior experience of team leaders Keith Parrish and Shaun of this very large observatory at a very low temperature despite Thomson from Goddard Space Flight Center and Perry being in an environment where it will constantly be bombarded Knollenberg from Northrop Grumman was essential to ensuring with 200,000 watts of solar energy—and to provide enough a robust thermal system. Through their past experience...
