In a major milestone, the James Webb Space Telescope’s mirrors and instruments have been mechanically mated with the spacecraft’s sunshield and subsystems during assembly operations at Northrop Grumman’s Redondo Beach, California, processing facility. The observatory’s science payload was lifted by crane and precisely positioned before being lowered and bolted into place. Engineers then completed mechanical connections and are preparing to make the required electrical connections.
