Since 1991, the dedicated and highly skilled crew at NASA's X-ray and Cryogenic Facility have been providing technology development and pre-flight verification of flagship missions like the Chandra X-ray Observatory and the James Webb Space Telescope. The XRCF at Marshall is the world's largest x-ray optical test facility and provides evaluation and readiness testing for advanced telescope mirrors, video guidance systems, and other space structures in thermal environments to 20 Kelvin.
