Primary Mirror Cryogenic Testing Six of the 18 James Webb Space Telescope mirror segments are being prepped to move into the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Ala., to eventually experience temperatures dipping to a chilling -414 degrees Fahrenheit to ensure they can withstand the extreme space environments. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures. Marshall's X-ray & Cryogenic Facility is the world's largest X-ray telescope test facility and a unique, cryogenic, clean room optical test location.

NASA engineers and Ball Aerospace subcontractors guide two mounted mirrors into a vacuum test chamber in the X-ray and Cryogenic Facility at NASA's Marshall Space Flight Center in Huntsville, Ala. The mirror tests completed recently at the facility will ensure the powerful mirrors -- the "eyes" of NASA's James Webb Space Telescope -- can withstand the extreme cold temperatures of space. The telescope, slated to launch in 2013, will study the most distant objects and phenomena in the universe. Ball Aerospace supports Northrop Grumman Corp., which is building the telescope for NASA.
