Space telescope Christmas launch culminates two decades of intense work
LOS ANGELES – For some people, it’s a memoir or a work of fiction; others, their first company or app. For Scott Willoughby, it’s a more than 13,000-pound telescope that must unfold while in space and work in cryogenic temperatures.
“Webb is my middle child,” Willoughby said of the James Webb Space Telescope – his baby of 12 years – launched Christmas Day from Kourou, French Guiana, on South America’s northern coast. It is a successor to the Hubble Space Telescope, which has observed distant stars and galaxies for more than 30 years but can’t see the first galaxies formed in the universe as Webb will be able to.
Willoughby, the telescope’s program manager at aerospace and defense company Northrop Grumman Corp., is part of a cadre of thousands of aerospace workers across NASA, Northrop and other firms who have devoted a huge part of their careers – some inadvertently – to this singular mission.
Their work spans nearly two decades, including about a decade of delays, numerous technical challenges and a hurricane that almost derailed a testing round. It culminated with the Dec. 25 launch, which Willoughby likened to seeing his two daughters leave home for college.
“When your kids leave home for that momentous occasion to start that adult life, ... you want them to do that and be successful, but you also want to follow them,” he said. “But you can’t.”
“I was only going to be on it for four to five years,” said Sandra Irish, NASA’S lead structures engineer for Webb. She has now worked on the program for 16 years.
Irish remembers crying as she watched the ship carrying the telescope, which was transported to the launch site in French Guiana from Seal Beach, California, pull into the harbor in October.
The Webb telescope is designed to look for faint infrared light – the first light to streak across the dark universe 13.8 billion years ago – that will allow scientists to understand more about the origins of the universe.
“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.
Much of the work on the telescope was groundbreaking, including the production of 18 hexagonal, lightweight mirrors and ensuring that Webb can function fully at cryogenic temperatures. Over the years, costs ballooned to $10 billion (earlier estimates ranged from $2 billion to $8 billion), and development setbacks delayed
the launch date.
“I’m the dinosaur,” said Charlie Atkinson, who has the longest tenure on Webb at Northrop Grumman: He started on the program in 1998 and now serves as its chief engineer.
Webb’s development lifespan has traced the trajectory of the lives that merged, took new paths and blossomed as its longest-serving creators built it up, year in and year out.
Careers lighted up. Friendships formed. Kids grew up and went to college, and still the telescope was in the making.
Atkinson’s twin daughters were born in 2000, while he was working on the proposal for Webb.
In May, Atkinson’s daughters will graduate from college.
“I sometimes tell people it feels like we sprinted a marathon,” said Lee Feinberg, optical telescope element manager at NASA Goddard Space Flight Center.
