The James Webb Space Telescope launches to space Christmas Day, the culmination of two decades of work: 'It feels like we sprinted a marathon.'
, including about a decade of delays, numerous technical challenges and a hurricane that almost derailed a testing round. It culminated with Saturday’s launch, which Willoughby likened to seeing his two daughters leave home for college.
“There wasn’t anything else out there that I could look at and improve on,” said Jim Flynn, director of vehicle engineering for the telescope at Northrop Grumman, who has been on the program for 17 years. The sun shield, made of a film material called Kapton that’s covered in a special coating, helps keep the telescope cool.The telescope will be able to peer into the farthest reaches of space. The data it collects will allow scientists to better understand the formation of stars and galaxies.
Careers lighted up. Friendships formed. Kids grew up and went to college, and still the telescope was in the making. Irish, who on a recent video call wore a dark blue shirt emblazoned with a white outline of the telescope — one of many in her Webb-branded clothing collection — keeps a photo of her children and now daughter-in-law, posing in front of the telescope, as her desktop image.
“There’s a lot of things we work on that you can’t share,” said Sarah, vice president of overhead persistent infrared and geospatial systems at Northrop Grumman.The most difficult challenge of her career, she said, was figuring out how to put Webb “on a diet” so it could meet the weight requirements of the Ariane 5 rocket, which will carry the telescope to space.
