Engineers have been working tirelessly to install all 18 of the final primary mirror segments, on what will be the biggest and most powerful space telescope ever launched.

Completing the assembly of the primary mirror, which took place at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is a significant milestone and the culmination of over a decade of design, manufacturing, and testing the agency’s James Webb Space Telescope.
