Its 18 hexagonal segments are made of lightweight beryllium coated with pure gold. 7–8 January 2022: Deployment of the two side panels forming JWST’s 6.5m primary mirror.6 January 2022: Deployment of the 1.2m x 2.4m Aft Deployable Instrument Radiator (ADIR), which radiates heat from the space telescope’s science instruments into space.The foldable structure supporting it has been dubbed “the world’s most sophisticated tripod”. NASAs Webb Telescope is using its superb angular resolution and near-infrared instruments to discover and study planetary systems similar to our own, analyzing. 5 January 2022: JWST’s 74cm convex secondary mirror is deployed. Astronomers using NASA’s James Webb Space Telescope have discovered a thread-like arrangement of 10 galaxies that existed just 830 million years after the big bang.While the Sun-facing side endures temperatures up to 90☌, the shielded side will be as cold as –230☌. 3–4 January 2022: The five Kapton layers of Webb’s sunshield are tensioned.30–31 December 2021: Sunshield mid-booms are extended on either side, pulling the folded sunshield layers with them, to form the first part of its distinctive 21m x 14m kite shape.29 December 2021: The Deployable Tower Assembly (DTA) is raised by 1.2m for better thermal isolation and to give room for the sunshield to unfold in front and behind.In just one year, the James Webb Space Telescope has transformed humanity’s view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the.
