Webb telescope microshutters journey into NASA clean room

This closeup of the four microshutter arrays shows some shutters open and some closed. 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. An open shutter lets light from a selected target in a particular part of the sky to pass through to NIRSpec’s detectors while a closed shutter blocks unwanted light from any objects that scientists don’t want to observe. A short video was created to show the transport of the flight microshutter device into a cleanroom at NASA Goddard on May 15, 2014, where it will undergo various tests for several months to verify its integrity and operation.
