## Caption

The James Webb Space Telescope's combined Optical Telescope element/Integrated Science instrument module inside of Chamber A, a giant thermal vacuum chamber located at NASA’s Johnson Space Center in Houston, Texas. Inside the chamber, the telescope endures tests at sub-freezing cryogenic temperatures.  The telescope will operate below an extremely cold 50 K (-223° C or -370° F) in space, so NASA is simulating those conditions on the ground, ensuring the optics and instruments will perform perfectly after launch.
