A new video from NASA shows a James Webb Space Telescope’s cameras and spectrographs being carried out of a Space Environment Simulator during NASA’s Goddard Space Flight Center in Greenbelt, Maryland. These vicious tools of a telescope endured their final super-cold exam here.

The Integrated Science Instrument Module, or ISIM, binds all of a Webb telescope’s cameras and spectrographs. The procedure is wrapped in special blanketing to keep all spotlessly clean.

For months, these components were tested inside a Space Environment Simulator. This simulator is a cylindrical cover 40 feet high and 27 feet wide. Vacuum pumps discharge a atmosphere within; and glass nitrogen and even colder gaseous helium dump a heat to copy a conditions in space where a Webb telescope will orbit. The contrast is vicious since these instruments contingency work during impossibly cold temperatures around reduction 387 F, or 40 kelvins. This is 260 F colder than any heat ever available on Earth’s surface.

After a exam a components were changed inside Goddard’s large purify room. The instruments will subsequent be integrated onto a look-out to join a telescope’s mirrors.

The scholarship instrument modules tested include of a mid-infrared instrument (MIRI), jointly grown by a nationally saved European Consortium underneath a auspices of ESA (the European Space Agency) and NASA’s Jet Propulsion Laboratory in Pasadena, California; a nearby infrared spectrometer (NIRSpec), jointly grown by Airbus for ESA and a U.S.; a Fine Guidance Sensor and Near-InfraRed Imager and Slitless Spectrograph, supposing by a Canadian Space Agency and grown by COM DEV International, Cambridge, Ontario, Canada; and Near Infrared Camera (NIRCam), built by a group during a University of Arizona and Lockheed Martin’s Advanced Technology Center.
