Inside NASA’s Goddard Space Flight Center’s massive clean room in Greenbelt, Maryland, the ninth flight mirror was installed onto the telescope structure with a robotic arm. This marks the halfway completion point for the James Webb Space Telescope’s segmented primary mirror.
The James Webb Space Telescope team has been working tirelessly to install all 18 of Webb’s mirror segments onto the telescope structure.
“The years of planning and practicing is really paying dividends and the progress is really rewarding for everyone to see,” said NASA’s Optical Telescope Element Manager Lee Feinberg.
The James Webb Space Telescope is the scientific successor to NASA’s Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, the European Space Agency and the Canadian Space Agency.
You can watch the telescope’s installation process live anytime on the JWST Webb Cam.
