The Frosty Treatment
During cryogenic testing, the mirrors will be subjected to temperatures dipping to -415 degrees Fahrenheit, permitting engineers to measure in extreme detail how the shape of each mirror changes as it cools.
Testing the Webb Telescope
Several critical items related to NASA's next-generation James Webb Space Telescope currently are being tested in the thermal vacuum test chamber at NASA's Goddard Space Flight Center, Greenbelt, Md. Image released April 30, 2012.
