Sun shield in place. Mirror deployment starts today. Sun shield seems a success, fingers crossed for the mirror.

secondary mirror in place. big primary mirror will be deployed over the next day or so. Every hurdle is critical to the function of the telescope. One tiny glitch could still see a big failure.

The James Webb Space Telescope is expected to begin unfolding its primary mirror today, Jan. 6, starting with the port side. In what could be a two-day process, Webb will unfold first the port side and then the starboard side wings of its 18-segment primary mirror, which is made up of shiny gold hexagons. There are three mirror segments on each wing. Each of the wings were folded for launch in order to fit inside the payload fairing of Webb's Ariane 5 rocket. While the mirror unfolding process is scheduled to take two days, it could occur faster. Webb's mission operations team has been running ahead of schedule for several key steps. NASA will webcast today's Webb mirror deployment on NASA TV. A time has not been released for the webcast's start. (space.com)

Big steps being taken on our one shot attempt to replace Hubble. If everything goes well it still won't be fully operational till summer but god knows what we could have learnt by this time next year. Edited by Stirlingsays (06 Jan 2022 4.43pm)

first of the two big mirror wings extended successfully
The James Webb Space Telescope unfolded the panel that carries the three leftmost segments of its hexagonal gold-coated primary mirror on Friday (Jan. 7). Nearly two weeks after the observatory's launch, the successful maneuver brings the telescope close to its final form. "Webb's iconic primary mirror is taking its final shape. Today, the first of two primary mirror wings, or side panels, was deployed and latched successfully," NASA officials wrote in a statement." (space.com)

The James Webb telescope. Even more far-sighted than CPFC transfer policy.

Now fully deployed. An elated mission team for NASA's James Webb Space Telescope confirmed that the space observatory is in great shape after a deployment phase that was 100% successful. "It is a fully deployed telescope ready to perform fantastic science to expand our knowledge," said John Durning, Webb Deputy Project Manager of NASA Goddard. Up next for the Webb team is a five-month commissioning phase to calibrate the telescope's optics and adjust its mirrors. Webb is currently making its way to its final observing site nearly 1 million miles (1.6 km) from Earth and is due to arrive around Jan. 23. To enter orbit around its Lagrange 2 point, Webb will have to perform a short manoeuvre, but it is expected to go well. (space.com, 20:30, 8 january 2022)

Or the BBC take on deployment,... "It's done. The biggest astronomical mirror ever sent into space is assembled and ready for focusing. The golden reflector, the centrepiece of the new James Webb telescope, was straightened out on Saturday into its full, 6.5m-wide, concave shape. The mirror had been folded like a drop-leaf table for the mission's Christmas Day launch. James Webb is set now to become a transformative tool in the study of all parts of the cosmos." (BBC)
