Image title	When the James Webb Space Telescope (JWST) reachesits orbit about a million miles (1.5 kilometers) fromEarth and begins studying the distant reaches of theuniverse, the event will mark an unprecedented triumphon several technological fronts.Aside from its 21.3-foot (6.5-meter) primary mirror —the largest and lightest ever flown — JWST will fly adeployable multi-layer sunshade. This tennis court -sized structure will block sunlight and prevent the coldsection of the observatory from exceeding -375° F(-233.3°C) — the temperature needed to detect faintinfrared light from distant astronomical objects andreveal more about the formation of planetarysystems.The microshutters used on the observatory’s NearInfrared Spectrograph also represent another technologicalbreakthrough. They, too, achieved a technologyreadiness level rating of six following an importantdemonstration test earlier this year. Originally conceivedwith Goddard R&D funding, the microshutter arrayconsists of 62,415 tiny shutters arranged in a waffle-like silicon grid. Through the application of a magneticforce, these shutters — each about the width of ahuman hair — open or close to allow or preventstarlight from entering the spectrograph. This way,astronomers can gather light from only those objectsthey want to study.JWST also is flying a super-cold mechanical cyrocoolerto keep instruments cool and state-of- the- art infrareddetectors.Photo Credit: Chris GunnSpring 2007
