James Webb Space Telescope
Center Of Curvature Optical Assembly (COCOA) at Excelis / ITT in Rochester, NY is being readied for transport to the Marshall Space Flight Center #39;s XRCF cryogenic vacuum test facility in Huntsville, AL. COCOA will allow the program to verify the optical performance of the 21.3-foot (6.5-meter) primary mirror at its 40 degrees Kelvin (-233 Celsius) operating temperature. The COCOA contains mechanical and optical instruments that allow the test team to identify, align and test the 18-segments from outside the vacuum chamber.From:Kowch737Views:7 1ratingsTime:01:47More inScience Technology
