JWST is the scientific successor to NASA’s 25 year old Hubble Space Telescope and will be the most powerful space telescope ever built.Webb is designed to look at the first light of the Universe and will be able to peer back in time to when the first stars and first galaxies were forming. It will also study the history of our universe and the formation of our solar system as well as other solar systems and exoplanets, some of which may be capable of supporting life on planets similar to Earth.The Webb telescopes huge primary mirror is comprised of 18 hexagonal-shaped primary mirror segments measuring 21.3-foot (6.5-meter) in diameter.They were installed onto the telescopes backbone structure by technicians assisted by a specially designed robotic arm. They worked day and night in a massive clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.The team used the claw-like robotic arm to meticulously latch onto each mirror —> Read More
