The James Webb Space Telescope fired its thrusters one more time Monday to reach its final parking spot a million miles from Earth. "Webb, welcome home," NASA Administrator Bill Nelson said in a statement after a five-minute burn added just 3.6 mph to the telescope's speed. "Congratulations to the team for all of their hard work ensuring Webb’s safe arrival at L2 today." L2 refers to a kind of stable orbit known as a Lagrange point. Technically, Webb is now orbiting the sun and is staying in line with Earth about a million miles away. The arrival at L2 capped off a treacherous 29 days in which everyone involved in the $10 billion program readily admitted the technical challenges were daunting. Every single thing had to work perfectly in order to launch, deploy mirror segments, and reach its final position. Moving forward, engineers will spend about three months aligning Webb's 18 gold-coated hexagonal mirrors to the final configuration. 🔗 Click the link in our bio to read more about its journey and arrival. #JamesWebbSpaceTelescope #NASA
