(Morning News) The main mirror of James Weber Space Telescope successfully opened in space on Saturday (January 8), marking that the telescope has been successfully "fully deployed."
For about half a month, the James Weber telescope will reach the observation location of about 1.6 million kilometers from the earth, stay on the earth's night, and run around the sun synchronously with the earth.After about half a year of inspection, the telescope will begin collecting data and the first batch of images. From then on, the tasks of the original galaxy that appeared after the formation of the universe and signs of search for outdoor life.
James Web Space Telescope, James Weber, was jointly studied and developed by the National Aeronautics and Space Agency (NASA) and the European Space Agency and the Canadian Space Agency.The telescope is the strongest and most cost -effective space telescope, which is considered the "successor" of the Hubble telescope.
James Weber Space Telescope costs about 10 billion US dollars, weighs 7 tons, and the main mirror diameter is 6.5 meters. It consists of 18 huge hexagonal mirrors.EssenceDue to the large size, the James Weber space telescope was filled with a folding state into the Aliana 5 rocket rectification cover.
Since launch, all the deployment of James Weber Space Telescope is controlled by a special team from the ground, and the team work every 12 hours.On the 7th, the staff expanded the left mirror of the main mirror.On the 8th, the mirror on the right also opened smoothly.
The New York Times reported that opening the main mirror is an important milestone in the deployment of the telescope.With the completion of this step, the National Aeronautics and Space Agency believes that the James Weber Space Telescope has been successfully "fully deployed."
It is reported that a few days ago, the staff successfully expanded the size of the tennis court size.This is the step that is considered the most failed risk.The huge sunshade plate designed as a 5 -layer thin film structure is located under the main mirror, which resists radiation from the sun, the earth and the moon for the telescope.
