After years of construction, the first of 18 primary flight mirrors has been installed onto NASA’s James Webb Space Telescope (JWST) at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, signifying the start of the final assembly phase for the mammoth observatory that will eventually become the most powerful telescope ever sent to space.
The milestone first mirror installation was achieved this week just ahead of the Thanksgiving holiday as the engineering team, working inside the massive clean room at NASA Goddard, used a robotic arm to precisely lift and lower the gold coated mirror into place on the observatory’s critical mirror holding backplane assembly.
