The telescope’s combined science instruments and optical element exits the massive thermal vacuum testing chamber after about 100 days of cryogenic testing inside it. Scientists and engineers at Johnson Space Center put JWST through a series of tests designed to ensure the telescope functioned as expected in an extremely cold, airless environment akin to that of space.
