Catalog – Technical Sciences – The James Webb Space Telescope’s heat shield has been successfully opened

The very important and complex process took a day and a half, as all the layers of the heat shield the size of a tennis court of the James Webb Space Telescope, which was launched on Christmas, were unfolded, a total of five layers. About the successful maneuver on the NASA website inform.

The heat shield is a sail-shaped canopy, which began unloading on Monday. The space telescope primarily uses its heat shield the way a man uses an umbrella on the waterfront to protect himself from heat and light. In the case of James Webb, sunlight and heat generated by the telescope’s sensitive instruments endanger its operation, compromising its operation. from kapton Armor is made of these.

As we wrote earlier, the JWST had to open into space because the telescope named after NASA’s second administrator was not suitable for the Ariane5 launch vehicle. In addition to the 21-by-14-meter heat shield, the 6.5-meter main mirror has been folded, which agency scientists have developed and operates a space lab that plans to open the latter over the weekend. Opening the heat shield, which keeps the devices below zero degrees Celsius, is the most sensitive of the mission, “Cause most sleepless nightsIt was described by NASA officials prior to his release.

The $10 billion telescope is a very sophisticated piece of equipment that was built in the United States under the supervision of NASA and also includes instruments from the European and Canadian space agencies. With these instruments, the instrument, announced as a successor to the Hubble Space Telescope launched in 1990, will explore the oldest era in the universe 13 billion years ago, a few hundred million years after the Big Bang, essentially looking back. NASA’s most efficient and complex space telescope will use infrared light to search the universe, planets and moons within the Solar System, the oldest and most distant galaxies for decades to come.

The James Webb Observatory is located one and a half million miles from Earth, and the Earth-Sun system is L2 from Lagrange It will observe objects in the solar system and record previously unattainable sensitivity and accuracy for five to ten years. After the launch, the space agency said JWST had enough energy to keep operating for years longer than planned.

Hungarian astronomers will also be able to make measurements with the telescope’s instruments, which are 100 times more powerful than the Hubble telescope.

Astronomers around the world will be eligible for valuable research time in space telescopes, and researchers working in ESA member states, including Hungary, will receive all available telescope time in exchange for the ESA’s contribution to the project.

The Miklós Konkoly Thege Astronomical Research Institute of the Center for Research on Earth and Astronomy Sciences (CSFK) has written a study of the effect of the eruption of the young star EX Lupi on the disk surrounding the star.

James Webb is currently a little more than halfway toward his 1.6 mile goal.
