The James Webb Space Telescope is fully deployed. So what’s next for the biggest observatory off Earth?

Work for the James Webb Space Telescope is just beginning.

On Saturday (Jan. 8), the new observatory, the largest space telescope ever built, successfully unfolded its final primary mirror segment to cap what NASA has billed as one of its most complicated deployments in space ever. The Webb mission team is now turning its attention to directing the telescope to its final destination, while getting key parts of the observatory online for its astronomy work.
