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, Maryland on August 29, 2013. 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. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, ESA (the European Space Agency) and the Canadian Space Agency. NASA Photo by Chris Gunn/UPI
