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. James Webb Space Telescope ENGINEERING SITE: Other WEBB Sites HOME WEBB IMAGES & LAUNCH NEWS ABOUT WEBB SCIENCE OBSERVATORY FEATURES & ACTIVITIES MULTIMEDIA Multimedia Overview Images Animations & Videos Scientific Viz Studio (SVS) MEET THE TEAM FOR SCIENTISTS FOR EDUCATORS FOR PRESS Item opens a new window.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”. 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☌. The James Webb Space Telescope (JWST), NASAs next flagship infrared observatory, developed in partnership with ESA and CSA, successfully launched on. Webb is an international program led by NASA with its partners, ESA (European Space. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Photons Incoming: Webb Team Begins Aligning the Telescope This week, the three-month process of aligning the telescope began and over the last day, Webb team members saw the first photons of starlight that traveled through the entire telescope and were detected by the Near Infrared Camera (NIRCam) instrument. 3–4 January 2022: The five Kapton layers of Webb’s sunshield are tensioned. The James Webb Space Telescope is the worlds premier space science observatory.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.They are really building up the anticipation. 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. Were still waiting on Nasa to release the first full-colour images from the James Webb Space Telescope, showing the Universe in detail like never before.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.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.
