Fox News
The James Webb Space Telescope hit another milestone this week and NASA announced that the $10 billion observatory's 18 hexagonal mirror segments and its secondary mirror have been fully deployed.
The process began last week, with the team moving the segments individually from their launch positions.
In a blog update, Erin Wolf – the Webb program manager at Ball Aerospace – wrote that the motors had made over a million resolutions this week, controlled through 20 cryogenic electronics boxes on the telescope.
