Photo Release -- Northrop Grumman, ATK Complete Primary Mirror Backplane Support Wing Assemblies For NASA's James Webb Space Telescope

The wing assemblies of the Webb Telescope's primary mirror backplane support structure were designed and fabricated and will be tested at ATK facilities in Magna, Utah. ATK designed and built the 900 composite parts of the wing assembly using lightweight graphite materials and advanced fabrication techniques. The composite parts attach to precision metallic fittings that provide interfaces with the other elements of the observatory. 

"The completion of the backplane wing assemblies continues to demonstrate state-of-the-art engineering and fabrication supporting this great NASA program," said Bob Hellekson, ATK's Webb Telescope program manager. "We are proud to be a partner in building this amazing telescope."

The James Webb Space Telescope is the world's next-generation space observatory and successor to the Hubble Space Telescope. The most powerful space telescope ever built, the Webb Telescope will observe the most distant objects in the universe, provide images of the first galaxies formed and see unexplored planets around distant stars. The Webb Telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.
