Northrop Grumman, NASA Complete Final Sunshield Deployment Test

REDONDO BEACH, CA (STL.News) Northrop Grumman Corporation (NYSE: NOC) and NASA have successfully completed the final sunshield deployment test on the James Webb Space Telescope in preparation for its 2021 launch.

“The success of this important milestone demonstrates the rigor and dedication of the Northrop Grumman and NASA team,” said Scott Willoughby, vice presi dent and program manager, James Webb Space Telescope, Northrop Grumman.  “The sunshield is designed to deploy in space and that is exactly what we validated during this final round of testing.”

Webb’s sunshield is a remarkable feat of human engineering and ingenuity designed to protect the telescope from light and heat emitted from the sun, Earth, and moon, and the observatory itself.  The sunshield maintains Webb’s one-of-a-kind scientific instruments in a deep cold, approximately negative 388 degrees Fahrenheit.

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.

Northrop Grumman solves the toughest problems in space, aeronautics, defense and cyberspace to meet the ever evolving needs of our customers worldwide.  Our 90,000 employees define possible every day using science, technology and engineering to create and deliver advanced systems, products and services.
