NASA has postponed the world's most powerful space telescope

The time to bring James Webb telescope to space is expected to fall to the beginning of 2021.

According to NASA's Independent Appraisal Council (IRB), despite slow progress, unexpected delays and costs incurred, the project continues, NTD reported on June 29.

"James Webb should continue to be based on extraordinary scientific potential and a crucial role in maintaining America's leading position in astronomy and astrophysics , " said Tom Young, chairman of the IRB. know.

Initially, the telescope was expected to launch into space in October 2018 but the plan was changed many times. The launch schedule for James Webb according to the latest announcement from NASA is March 30, 2021.

The initial cost to develop James Webb is 8 billion USD. Due to some difficulties, this number has increased to 8.8 billion USD. The total cost of project implementation is estimated at 9.66 billion USD. Not only technical problems but human errors also contribute to slowing the project, the IRB said.

The James Webb telescope is expected to be a great step forward in observing the universe. When completed, it will operate about 1.5 million kilometers from Earth and focus on distant galaxies. James Webb will have less obstructed vision than a ground telescope or Hubble space telescope.

James Webb will be 100 times more sensitive than Hubble, according to NASA. It can "look back" time and space, watching the first stars form in the early universe. James Webb will be folded to launch into space by Ariane rocket 5. When opened, this telescope's main mirror has a diameter of 6.5m.
