James Webb Space Telescope Begins Lining Up Its Golden Mirrors

Engineers have started turning 18 gold-plated mirrors on NASA’s James Webb telescope. Once aligned, the giant mirror can collect even the faintest light from the universe.

The team also commanded 126 actuators for moving and shaping the segments into place. The six devices will then position the secondary mirror and verify its workings. “The fine steering mirror is critical to the process of image stabilization,” stated NASA.

NASA’s ground station is working and instructing the primary and secondary segments of the mirror. “These movements will take at least ten days, after which engineers can begin the three-month process of aligning the segments to perform as a single mirror,” explained the space agency.

The James Webb Telescope is on its way to L2, the second Lagrange point located 15,00,000 kilometers from Earth. Completing the unfolding took over 15 days as the ground team had to open sun shields and secondary mirrors before opening the two folded parts of the primary mirrors.

Currently, it is in its commissioning period. This involves the cooling period, checking, and alignment of the mirror segments.

Additionally, all instruments in the panel have to undergo calibration. The telescope will soon go through a correction burn for placing itself on the L2 orbit. Once set, it can help us with peering back to more than 13.5 billion years in the past. The telescope is crucial in not just understanding the past of the universe but also studying distant worlds, waiting to be discovered.
