With the successful deployment & latching of its last mirror wing, that's:
50 major deployments, complete.
178 pins, released.
20+ years of work, realized.
Watch as scientists from the James Webb Space Telescope provide real-time updates on the observatory's final deployment step: the unfolding of the second of Webb's two primary mirror wings. Mission control engineers will send commands to deploy and fasten the wing into position, a process that will take several hours. The deployment will complete the mirror's golden honeycomb-like structure and bring the 14-day unfolding procedure to a close. ЁЯОЙ
