James Webb Space Telescope Arrives at New Home in Space


After traveling almost a million miles, NASA’s James Webb Space Telescope reached its final destination yesterday.

The most powerful observatory ever to launch to space, the James Webb Space Telescope lifted off on Dec. 25, 2021 to explore the cosmos and our universe’s earliest milestones. Since its successful takeoff, the $10 billion telescope has been busy deploying its various systems and structures and traveling over 930,000 miles (1.5 million kilometers) to its new home: L2, the second sun-Earth Lagrange point, which it will orbit. Lagrange points are gravitationally stable points in space.

Today, 30 days after launch (and after a one-day delay), Webb arrived at L2.

“Webb, welcome home!” NASA Administrator Bill Nelson said in an agency blog post. “Congratulations to the team for all of their hard work ensuring Webb’s safe arrival at L2 today. We’re one step closer to uncovering the mysteries of the universe. And I can’t wait to see Webb’s first new views of the universe this summer!”
