Harris Corp. has installed the ninth flight mirror onto NASA’s James Webb Space Telescope structure at Goddard Space Flight Center in Greenbelt, Maryland.
The installation marks the progress of the telescope’s segmented primary mirror halfway to completion, which is scheduled for 2016, NASA said Tuesday.
The engineering team used a robotic arm to lift and lower the segment onto the telescope.
Ball Aerospace & Technologies built the mirrors for Webb’s prime contractor Northrop Grumman, which developed the optical technology and lightweight mirror system.
James Webb Space Telescope is a partnership project between NASA, the European Space Agency and the Canadian Space Agency.
