The James Webb Space Telescope has finally opened completely in space

A moment ago, NASA also confirmed the deployment of the James Webb Main Mirror, a two-week opening operation and the complete deployment of the Space Telescope in final alignment with Success is over.

The James Webb Space Telescope was launched from the French Guiana Space base in South America two weeks ago, just at the beginning of Christmas. Now, two weeks after his Space trip, the complex operation of deploying this scientific tool is complete.

Due to the large dimensions of the James Webb Space Telescope and its tools such as the solar shield, it was not possible to place it in the launcher without folding, and therefore the Telescope with a complex origami mechanism in The Space was opened to be in its final arrangement and ready for lighting.

The web opened at the beginning and moments after the launch of the solar cells. After that, web structural pallets were deployed and the base of scientific tools was raised. Then James Webb's sun shield, which is the size of a tennis court, was installed in several steps over several days. The installation of the radiator and the secondary mirror were the next steps taken in the past few days.

Finally, it was the turn of the main mirror of the James Webb Telescope and Eye. The main mirror installation operation started yesterday with the opening of the left wing (wing or port arm) and continued today with the opening of the right wing (wing or starboard arm). Each of the wings or arms of the main mirror has three hexagonal mirrors out of a total of 18 mirrors that bring the total diameter of the main mirror to 6.5 m.

The installation of the mirror sections was done using motors that each They turned one of the wings on a special hinge and put it in its final position. Thus, the last part of the mirror was in place just before 10:30 in the Eastern time zone (19:00 Tehran time). This operation was performed to ensure the stability of these structures in all directions. This stability is essential for the precise positioning of each mirror next to the other and the possibility of observation. "We now see that beautiful pattern in the sky that is almost perfect. I'm amazed at that." "I'm very pleased to see the mirrored sections all together so well at this time." Tehran) was confirmed. With the successful opening of the Web, 50 major deployment steps have now been completed, 178 pins have been released, and more than 20 years of effort have paid off.

Since the completion of the main mirror deployment, the web has taken an important deployment step. Now, however, is the beginning of another difficult and very sensitive process.

Although today's operation is the last step It was the main location of the observatory complex, but with the full deployment of the James Webb Telescope, a five-and-a-half-month period has now begun, during which the necessary operations will be carried out for the first exposure and the start of scientific operations. This process involves placing mirrors and Telescope assemblies at a stable cryogenic operating temperature, fine-tuning each of the 18 mirrors individually, and calibrating scientific instruments. The James Webb Space Telescope is currently about 1.1 million kilometers from Earth. It is about 75 percent of the way away, and is two weeks away from being in the Lagrangian orbit of point 2 (about 1.5 million kilometers from Earth). As the spacecraft's propulsion operates in only one direction, its speed is gradually reduced to allow it to orbit.

The main mission of the Web is to look at the first stars and galaxies in the universe, to identify extrasolar planets. , The discovery of fascinating chemicals in different parts of the universe and other outstanding scientific missions. For this reason, optics and scientific instruments must be kept very cool to receive weak thermal signals from the farthest corners of the universe.

If all goes according to plan, the web is a joint effort of NASA, the European Space Agency and The Canadian Space Agency will begin its much-anticipated scientific mission in late June (early July) or early July (mid-July) and will continue to observe the universe for at least five years.
