NASA’s Webb Space Telescope Receives First Mirror Installation

NASA

NASA has successfully installed the first of 18 flight mirrors onto the James Webb Space Telescope, beginning a critical piece of the observatory’s construction.

In the clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland this week, the engineering team used a robot arm to lift and lower the hexagonal-shaped segment that measures just over 4.2 feet (1.3 meters) across and weighs approximately 88 pounds (40 kilograms). After being pieced together, the 18 primary mirror segments will work together as one large 21.3-foot (6.5-meter) mirror. The full installation is expected to be complete early next year.

The story is too old to be commented.

The technology behind that telescope is just breathtaking. Would aliens consider us a peeping tom, though, staring at their planets like a kid looking through his binoculars in a tree?
