With surgical precision, two dozen engineers and technicians successfully installed the package of science instruments of the James Webb Space Telescope into the telescope structure.
The package is the collection of cameras and spectrographs that will record the light collected by Webb’s giant golden mirror.
The time-lapse video (directly below) shows the Webbcam view of the world's largest clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland as the James Webb Space Telescope is lifted to the assembly stand in prep for instrument installation.
