Dynavac supplied gaseous helium-cooled shrouds to test both subsystems and the entire James Webb Space Telescope (JWST). Temperatures as low as 20k were needed to subject the spacecraft to the cold of deep space. Dynavac’s engineering, manufacturing, and field teams solved novel design and construction challenges presented with cryogenic panels up to 12 by 40 feet, and over 7000 critical welds needed for fabrication.
