Preparation for 2021 launch

Redondo Beach, California. 19 December 2020. Northrop Grumman and NASA Complete Final Sunshield Deployment Test on the James Webb Space Telescope. To fully deploy Webb’s sunshield, the team activates its components and executes a series of commands that initiates the release of devices which free the sunshield’s five layers. Following the release of several more cable restraint devices, a highly coordinated series of individual motor movements are completed, deploying then tensioning each sunshield layer one by one. Lastly, these actions allow the sunshield to take its final diamond-like form via a system of pulleys and springs.

The next series of major milestones includes completing the final wing deployments of Webb’s primary mirror to verify flight worthiness, followed by a final and complete full systems evaluation before shipping to the Kourou, French Guiana launch site

Northrop Grumman leads the industry team for NASA’s James Webb Space Telescope, the largest, most complex and powerful space telescope ever built. NASA leads an international partnership that includes the European Space Agency and the Canadian Space Agency. Goddard Space Flight Center manages the Webb Telescope project, and the Space Telescope Science Institute is responsible for science and mission operations, as well as ground station development.
