NASA Shines a Spotlight on a Webb Telescope Test

Dressed in a clean room suit, NASA photographer Desiree Stover shines a light on the Space Environment Simulator's Integration Frame inside the thermal vacuum chamber at NASA's Goddard Space Flight Center in Greenbelt, Md. Shortly after, the chamber was closed up and engineers used this frame to enclose and help cryogenic (cold) test the heart of the James Webb Space Telescope, the Integrated Science Instrument Module.
