Updated 1. 1. 2021 The James Webb Space Telescope has another major milestone. He was able to spread out both of his arms for the heat shield, protecting him from the sun’s rays while observing outer space.
It shines like a diamond 💎
With the successful deployment of Wasit’s right-hand sunshade, or “arm,” the Webb sunscreen has now taken on its diamond shape in space. Next up: Tighten the five layers of sunblock! https://t.co/6G2caS1djY #UnfoldTheUniverse pic.twitter.com/q0iuHdnKlN

Before starting, this shield was held in place by as many as 107 locking mechanisms, and the successful deployment proved the functionality of each of them. This is followed by an expansion process, in which 5 individual layers are separated – this is followed by a press conference by NASA, says SPACE.
However, before the JWST takes that step, it is taking an important break and work will continue on Sunday, January 2, 2022.
Updated on 12/30/2021 – JWST is on its way to release point L2, where it has to make some corrections with its own engine. However, to the surprise of scientists, the Ariane 5 rocket carried it into space with such precision that it used much less fuel to make the corrections than planned.
This means that the most important space telescope in the history of astronomy will last much longer than the planned ten years, CNET. The space observatory needs fuel to stay in its specified orbit between the Earth and the sun.
Updated: 28. 12. 2021 – The James Webb Space Telescope, which entered space only a few days ago, is already preparing for the most important operation in the universe that a human spacecraft has ever attempted, Informuje interesting geometry.
This process, in which 344 different operations can fail, has already begun and will take several weeks. However, as NASA’s Thomas Zurbechen said, although the JWST appears very complex, it is already equipped with the best possible solutions.
A moment ago, JWST expanded the structure with a heat shield, which will gradually spread up to 5 layers to protect the observatory from sunlight, which could heat it up and disrupt the observation.
Updated on 12/26/2021 – Specialists with the National Aeronautics and Space Administration (NASA) conducted the first of three maneuvers planned to correct the course of the James Webb Telescope, Taser said, citing a NASA statement Sunday morning.
This correction lasted 65 minutes. NASA explains that the correction brought the telescope’s flight in line with the second Lagrangian point, approximately 1.5 million kilometers from Earth. The journey to this point is expected to take about four weeks.
The James Webb Telescope launched the Ariana 5 launch vehicle into orbit on Saturday from Kourou Spaceport in French Guiana. It is a joint project of NASA, the European Space Agency and the Canadian Space Agency.
The telescope has a system of mirrors with a diameter of 6.5 meters – the largest ever launched into orbit. With its help, it will be possible to study the oldest stars and galaxies in the universe, which formed after the so-called Big Bang, and search for potentially habitable planets. Its design life is ten years.
US President Joe Biden and Vice President Kamala Harris congratulated the NASA team on Sunday on the success of the mission. The success was also highlighted by the American businessman Elon Musk, founder of Tesla and SpaceX. The telescope is named after the second administrator of NASA, James E. web.

13:48 The final stage of the Ariane V rocket has turned off its engine and separated from the James Webb Space Telescope. It is now in orbit alone, 1.5 million kilometers from Earth. Solar panels and long-range communications equipment will soon be deployed, but full deployment will take weeks and astronomers still can’t quite breathe.
13:25 – All telemetry is still in order, the rocket was separated from additional solid-fuel rocket engines and later aerodynamic cargo casings, which protect the payload during flight through the atmosphere.
13:20 The James Webb Space Telescope has finally been launched from France, aboard an Ariane rocket.
Updated December 25th at 12:30pm. Ariane V rocket with James Webb Space Telescope ready on the launch pad and full of fuel. The flight is still scheduled for 13:20 our time and the countdown continues without any issues.
By far, the most important piece of space technology humanity has ever devised is finally getting ready for its spaceflight after a long delay. The James Webb Space Telescope (JWST) is ready for an Ariane 5 rocket and will fly within hours, informuje every day an astronaut.
Definition of extreme complexity
According to NASA, the launch is currently scheduled for December 25 At 13:20, the space telescope will launch a European Ariane V rocket. The mission takes place at a spaceport in French Guiana and the telescope will finally anchor at release point L.2 Between the Sun and the Earth, it reaches 1,500,000 km from Earth at its furthest point.
NASA already has a live broadcast on its YouTube channel, but the mission will also be available through well-known channels such as NASAS space flight whose astronaut every day. FonTech.sk will also share important updates related to this historic mission through updates to this article.
NASA, the European Space Agency (ESA), the Canadian Space Agency (CSA), and the Space Telescope Science Institute are collaborating on the mission. The task will take a long time, as the full deployment will not take place until 14 days after launch.
The most comprehensive series of tasks
The process of disassembling this telescope is so complex that it is the most complex series of operations ever attempted by a man-made object in space. NASA writes. The number of moving parts must be matched and located precisely, and the reserves must be minimal.
Also for this reason, it is the most troubling task for all astronomers, who do not easily let go of their tension and fear until the telescope is fully expanded. If all goes well, he will do his job for ten years.
Since the L2 release point is unstable, the space telescope will need to use its own thrust regularly to stay on it. Also for this reason, it is almost impossible to expect that his service life will be much longer than planned. It is theoretically possible to refuel, but given the distance, this option is still only theoretical.
Finally we got the answers
how to continue NASA explainsThe James Webb Space Telescope was primarily designed to observe the first stars and galaxies that began forming 13.5 billion years ago. Because of the redshift, the visible and ultraviolet light of these objects, especially the infrared radiation that this telescope is supposed to detect, has changed – In particular, its nature is different from that of the Hubble telescope.
However, in addition to being able to observe distant objects with the highest resolution and accuracy to date, scientists can also use it to explore the nearest universe. The telescope is also supposed to examine exoplanets more closely, which are located in potentially habitable areas of their parent stars and there is a chance of life on them.
Incredible display of technology
According to the Canadian Space Agency It’s the most ambitious space observatory we’ve ever sent into space or attempted to do – although astronomers are already looking to the future and asking Several times larger than telescopes or even observatories on the moon.

The JWST base mirror measures 6.5m in diameter and consists of 18 gold-plated hexagons. The observatory also has a biodegradable sun visor, which consists of 5 layers and, when opened, reaches the dimensions of a tennis court. This will ensure that the space telescope is below 50 K, that is, below -223.2 degrees Celsius, so that it does not shine in the infrared spectrum and does not interfere with its observations.
Lots of science tools
In addition, JWST is equipped with four scientific instruments, such as the near-infrared camera (NIRCam, manufactured by the University of Arizona), the near-infrared spectrometer (NIRSpec, manufactured by the European Space Agency), and the medium-infrared instrument (NIRSpec, manufactured by the European Space Agency). MIRI). Manufactured by NASA in cooperation with European countries) and finally FG / NIRISS, i.e. sensitive navigation sensor, near-infrared display and non-slitting spectrometer.

This project was delayed for many years and did not meet the originally planned schedule, under which it was scheduled to fly as early as 2007. The budget, which eventually exceeded the JWST several times, was not the best.
However, in this case, it is really true that it is not possible to put a price on science. JWST has tremendous potential to fundamentally transform our understanding of the universe and take many of our scientific disciplines to a whole new level. All that remains is for you to succeed.
