Webb Telescope Microshutters Journey into NASA Clean Room

NASA's James Webb Space Telescope microshutters have taken a short jaunt in preparation of its million mile journey in four years. The microshutters were moved into a NASA Goddard cleanroom for testing to verify they work correctly before being installed in the Webb's Near Infrared Spectrograph (NIRSpec) instrument.

NIRSpec is a powerful instrument that will record the spectra of light from distant objects. The microshutters, a key component of NIRSpec, are a new technology specifically developed for the Webb telescope. They only let light in from selected objects to reach NIRSpec's detectors.

JWST Microshutters Moved for Thermal, Accoustic and Vibration Testing

A new Microshutter Array for the Webb Telescope's Near Infrared Spectrometer (NIRSpec) is packed and transported by hand one building away at NASA Goddard Space Flight Center to undergo thermal cycling testing and checkouts at it operational temperature of 35 kelvin or -397 Fahrenheit.
