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.Galaxy NGC 5068 lies within the Virgo constellation, which is home to an enormous cluster of galaxies. 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. NASAs James Webb Telescope peeks behind gas clouds in galaxy 20 million lightyears away.The foldable structure supporting it has been dubbed “the world’s most sophisticated tripod”. 5 January 2022: JWST’s 74cm convex secondary mirror is deployed. 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.The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope. 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. The James Webb Space Telescope (JWST) is a space telescope currently conducting infrared.28 December 2021: The Forward Unitized Pallet Structure (UPS), which supports and contains the five folded layers forming the front half of the sunshield, is lowered into place.26 December 2021: Deployment of the high-gain communications antenna, which allows communication with Earth through NASA’s Deep Space Network.The telescope can now switch from battery power to its own power. 25 December 2021, 12:48 UT Deployment of JWST’s 6m, five-panel solar array, which delivers about 1Kw of power. The NASA James Webb Space Telescope, developed in partnership with ESA and CSA, is operated by AURAs Space Telescope Science Institute.25 December 2021, 12:20 UT: JWST launches from the Guiana Space Centre on an Ariane 5 rocket after 27 minutes, it separates from the launcher’s upper stage to travel to L2 alone.Here's a timeline of how it all took place.
