SPACE reports that the James Webb Space Telescope deployed its Aft Deployable Instrument Radiator (ADIR) Thursday at about 8:38 a.m. EST. The ADIR “is a 4 foot (1.2 meters) by 8 foot (2.4 m) panel attached to the back of the observatory and connected by aluminum foil straps to Webb’s instruments. The radiator is covered in honeycomb cells with an ultra-black surface, allowing the mechanism to pull heat away from the observatory instruments and send it into space.”
