The James Webb Space Telescope's secondary mirror installation operation was successfully completed an hour ago to bring this sophisticated scientific instrument closer to its final form in space.

As expected, the web deployment timeline changed slightly during the mission. The traction of the sunscreen was finally completed yesterday, the tenth day after launch, and the installation of the secondary mirror, according to a new schedule, took place today.

In Baltimore, Maryland, it also had a live broadcast.

For this deployment, the secondary mirror of the James Webb Space Telescope was successfully opened first, but the mission controllers paused briefly to verify the situation. They then secured the secondary mirror in their final configuration.

This optical instrument is located at the end of the secondary mirror support structure (SMSS), and while the SMSS is deployed, the long tripod stands Each, which is about 7.6 meters long, turned the secondary mirror out in front of the main mirror.

The installation process took place at approximately 09:52 Eastern time (18:22 Tehran time). Started and the secondary mirror reached its open position at about 11:28 AM Eastern time (19:58 Tehran time) until finally at 11:51 AM Eastern Time (20:21 Tehran time) the secondary mirror support structure Lock in place. The operation was confirmed at 12:23 a.m. (20:53 Tehran time).

Thus, the secondary mirror of NASA's James Webb Space Telescope is now securely locked in place, successfully completing today's deployment phase. is showing. The deployment is the latest step in the complex process of deploying the James Webb Space Telescope.

The secondary mirror plays an important role in reflecting light from the primary mirror to the location of optical instruments behind the primary mirror. In the next few days, the web radiator will also open its rear, which will then expand its two side sections or the main mirror wing from the retracted position. Operations that will mark the final stage of the telescope's original deployment. Once completed, scheduled for 15 days after launch, the next important step will be to get the web into orbit around Lagrangian Point 2.
