On December 25, 2021, we witnessed an historic event in the world of astronomy. The Ariane 5 rocket from the spaceport in French Guiana has taken off into space James Webb Space Telescope, which is the result of many years of cooperation between scientists from NASA, ESA and the Canadian Space Agency. The rocket launch had been postponed many times before, which raised doubts as to whether it would be launched before the new year.
NASA announced another success with the placement operation James Webb Space Telescope in L2 orbit. This time the sun visors were fully unfolded. However, it was not without problems and in the last few days everyone involved in the project was under great stress. Finally, they managed to complete the process on which the success of the entire mission depended.
Thermal shields are essential for the proper operation of the James Webb Space Telescope, as it will look at the Universe in infrared light. It must therefore be free from infrared radiation sourcesthat could disrupt his work. Therefore, heat shields will separate the mirrors from the sun. The instrument is perfectly adapted to operation in extreme conditions, the temperature on the side of the mirror will be close to absolute zero. This will be observable celestial bodies formed over 13.5 billion years ago.
Successful deployment of heat shields it is not the last leg of the James Webb Space Telescope journey. The instrument had to be assembled due to its size, otherwise it would not fit in the rocket that transported it. Earlier, NASA reported the successful deployment of the antenna, and then the solar panels. In the following days, the procedure of unfolding the secondary mirror, and then the most important element – main mirror.
The official NASA website reports that currently the James Webb Space Telescope he has already defeated over 65 percent. distances between the earth and the target orbit. According to scientists’ estimates, the observation instrument should arrive there already around January 22. After that, the device must be properly calibrated and tested. The first photos taken by the telescope we will be able to watch it as soon as possible in June.
