NASA’s James Webb Space Telescope will be looking at the universe with infrared vision. In order to optimally accomplish this mission, the observatory has to be kept as cold as possible. A carefully designed set of 5 coated layers of a special material called Kapton work together to enable the heat to be deflected from the telescope. This episode of Behind the Webb shows what the deployment of the sunshield and its layers looks like from the ground.
