What is Webb?

Northrop Grumman led the industry team for NASA’s James Webb Space Telescope (JWST), the largest, most complex and powerful space telescope ever built.

The Webb Telescope fundamentally alters our understanding of the universe. Northrop Grumman ensured that this once unthinkable achievement became a reality. Identified as a top priority for astronomy and astrophysics by the National Research Council, the Webb Telescope is a key program for NASA and the scientific community and is central to the nation’s ground- and space-based astrophysics program.

What it Was Like to Work on Webb

Before we could begin to build the most complex telescope ever, we had to invent technologies that never existed before. For many Northrop Grumman employees, the opportunity to work on Webb was the opening for boundless opportunity. From a new element on the Periodic Table and embracing digital transformation to creating zero gravity here on earth, Northrop Grumman employees developed something that the entire universe can be proud of.

How Webb is Defining Possible

NASA’s Webb Telescope is using its superb angular resolution and near-infrared instruments to discover and study planetary systems similar to our own, analyzing the molecular composition of extrasolar planets’ atmospheres and directly imaging Jupiter-size planets orbiting nearby stars.

Webb is making observations once thought to be impossible; multiple new technologies had to be invented simply to build it. The groundbreaking mirror and powerful instruments are being used to discover and study distant planetary systems.

Webb is also looking deep into the past, to a time when the earliest stars and galaxies were born. By extending our knowledge of the cosmos, the Webb telescope will help us answer the compelling questions, “How did we get here?” and “Are we alone?”

The Webb Team

NASA led the international partnership that included the European Space Agency and the Canadian Space Agency. NASA’s Goddard Space Flight Center is managing the Webb Telescope project, and the Space Telescope Science Institute is responsible for science and mission operations, as well as ground station development.

As the prime contractor to develop the James Webb Space Telescope, Northrop Grumman designed and built the deployable sunshield, provided the spacecraft and integrated the total system. The observatory subsystems were developed by a Northrop Grumman-led team with vast experience in developing space-based observatories.
