(Phys.org)—The Center of Curvature Optical Assembly, or COCOA, is a piece of equipment that will measure the accuracy of NASA's James Webb Space Telescope's primary mirror, to ensure the mirrors are perfectly shaped and will work in the frosty environment of space. Viewers can now learn about a certain type of "COCOA" from an engineer in a new behind-the-scenes NASA video that explains the purpose of COCOA and how it is used in testing the mirrors.
