Webb Telescope Completes Final Cryogenic Testing
NASA’s James Webb Space Telescope sits inside Chamber A at NASA’s Johnson Space Center in Houston after having completed its final cryogenic testing on Nov. 18, 2017.
Webb’s combined science instruments and optics underwent about 100 days of testing inside the chamber. The end of the testing is a significant milestone in the telescope’s journey to the launch pad.
“The individuals and organizations that have led us to this most significant milestone represent the very best of the best. Their knowledge, dedication, and execution to successfully complete the testing as planned, even while enduring Hurricane Harvey, cannot be overstated,” said Mark Voyton, James Webb Space Telescope optical telescope element and integrated science instrument manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. “Every team member delivered critical knowledge and insight into the strategic and tactical planning and execution required to complete all of the test objectives, and I am honored to have experienced this phase of our testing with every one of them.”
