The two halves of NASA’s James Webb Space Telescope now reside at Northrop Grumman Aerospace Systems in Redondo Beach, Calif., where they will come together to form the complete observatory.

Webb’s optical telescope and integrated science instrument module (OTIS) arrived at Northrop Grumman on Feb. 2, from NASA’s Johnson Space Center in Houston, where it successfully completed cryogenic testing.

“This is a major milestone,” says Eric Smith, director of the James Webb Space Telescope Program at NASA. “The Webb observatory, which is the work of thousands of scientists and engineers across the globe, will be carefully tested to ensure it is ready to launch and enable scientists to seek the first luminous objects in the universe and search for signs of habitable planets.”

In preparation for leaving Johnson, OTIS was placed inside a specially designed shipping container called the Space Telescope Transporter for Air, Road and Sea (STTARS). The container then was loaded onto a U.S. military C-5 Charlie aircraft at Ellington Field Joint Reserve Base, just outside of Johnson. From there, OTIS took a flight to Los Angeles International Airport. After arrival, OTIS was driven from the airport to Northrop Grumman’s Space Park facility.

“It’s exciting to have both halves of the Webb observatory — OTIS and the integrated spacecraft element — here at our campus,” said Scott Willoughby, vice president and program manager for Webb at Northrop Grumman. “The team will begin the final stages of integration of the world’s largest space telescope.”

During this summer, OTIS will combined with the spacecraft element to form the complete Webb observatory. Once the telescope is fully integrated, the entire observatory will undergo more tests during what is called observatory-level testing. Webb is scheduled to launch from Kourou, French Guiana, in 2019.

The James Webb Space Telescope is the world’s premier infrared space observatory of the next decade. A barrier-breaking mission for engineers and astronomers, Webb will solve mysteries of our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it.  The scientific complement to NASA's Hubble Space Telescope, the Webb assembled in a Class 10,000 cleanroom at NASA's Goddard Space Flight Center. Webb is an international project led by NASA with its partners, ESA (European Space Agency), and CSA (Canadian Space Agency).
