The James Webb Space Telescope is designed to unfold after it is deployed and in orbit. The primary mirror with its 18 segments is held in place by a honeycomb-like structure called a backplane. This has three parts -- a center section and two wings. "Behind the Webb" video series host Mary Estacion travels to ATK in Magna, Utah, where the backplane and, in particular, the wings are built.
The James Webb Space Telescope is being built by NASA in cooperation with the European Space Agency and the Canadian Space Agency. The telescope is expected to launch in 2018.
