NASA’s James Webb Space Telescope sits in front of the door to Chamber A, a giant thermal vacuum chamber located at NASA’s Johnson Space Center. The telescope will soon be moved into the chamber, where it will spend a hot Houston summer undergoing tests at sub-freezing cryogenic temperatures. The telescope will operate at an extremely cold 39 K (-234° C or -389° F) in space, so NASA is simulating those conditions on the ground, ensuring the optics and instruments will perform perfectly after launch.
