Webb’s MIRI Shield Dropping in on Dropping Temperatures
Goddard Technicians Tony Kiem (left) and George Mooney (right) guide the craned structure holding the Webb telescope’s Mid-Infrared Instrument or MIRI Shield Environmental Test Unit into place in a cryogenic (cooling) test chamber. This shield will be used to simulate the MIRI instrument during prelaunch testing to verify that the MIRI cooling system will function properly in space.
