Webb telescope’s launch delayed until 2020
James Webb Space Telescope mirror installation halfway complete
Inside NASA’s Goddard Space Flight Center’s massive clean room in Greenbelt, Maryland, the ninth flight mirror was installed onto the James Webb Space Telescope’s structure with a robotic arm. After being pieced together, all 18 primary mirror segments will work together as one large 6.5-metre mirror. The full installation is expected to be complete early in 2016.
