Technicians successfully performed a critical test on Webb's 5-layer sunshield by fully deploying each of its uniquely sized layers to the same position that they will have while orbiting the Sun a million miles away from Earth.
As an infrared optimized telescope, it is imperative that Webb’s optics and sensors remain impressively cold, and its sunshield is key for temperature regulation. The sunshield separates the observatory into a warm side that always faces the Sun, and a cold side that always faces deep space. October 2019.
