Moving the JWST ISIM to the cryo-vacuum test chamber
Moving the JWST Integrated Science Instrument Module (ISIM) from a clean room at the Goddard Space Flight Centre to the Space Environment Simulator for the third long-duration cryo-vacuum test, known as ISIM CV-3.
ISIM houses the four JWST instruments: NIRSpec (Near Infrared Spectrograph), MIRI (Mid-Infrared Instrument), NIRCam (Near-Infrared Camera), and FGS/NIRISS (Fine Guidance System/Near-InfraRed Imager and Slitless Spectrograph).
