Preparing the James Webb Space Telescope (JWST). Webb's science instruments and optical element together exited the massive thermal vacuum testing chamber after about 100 days of cryogenic testing inside it. Scientists and engineers at Johnson put Webb through a series of tests designed to ensure the telescope functioned as expected in an extremely cold, airless environment akin to that of space.
