The giant James Webb Space Telescope of the (NASA) achieved a key pre-launch test

Webb Space Telescope

This is the largest and most powerful space telescope in the world, and its giant golden mirror was last unveiled on Earth on Tuesday. This is a major milestone ahead of the US $ 10 billion (about 73,440 crores) observatory launch later this year. 

NASA stated that its 21-foot 4-inch (6.5-meter) mirror was required to be fully extended and locked in place; This is a final test to ensure that you can survive a million mile (1.6 million kilometers) journey. And ready to discover its origin is like building a Swiss watch at a height of 40 feet … and preparing for this trip, we work in a vacuum of minus 400 degrees Fahrenheit (-240 degrees Celsius), which is higher than before, said Scott Willoughby of Northrop. Grumman, Quadruple’s prime contractor. 

Released on October 31st. Weber’s main pick mirror is made of 18 hexagonal parts, coated with an ultra-thin gold layer to enhance its reflection of infrared light, it will fly into space folded like an origami work of art, making a size of 16 feet (5 inches). (interior-m) the rocket fairing is fitted, and then 132 independent actuators and motors will be used to bend each mirror to a specific position. 

Together, these mirrors will act as a giant reflector, allowing the telescope to look deeper into the universe than ever before.

“The primary mirror is a technological marvel. The lightweight mirrors, coatings, actuators and mechanisms, electronics and thermal blankets when fully deployed form a single precise mirror that is truly remarkable,” – Lee Feinberg, optical telescope element manager for #NASAWebb pic.twitter.com/l5Z4MBPLka

Scientists hope to use telescopes to go back 13.5 billion years and see for the first time the first stars and galaxies formed hundreds of millions of years after the Big Bang, for which they need to detect infrared rays. 

The Hubble telescope, the most advanced space telescope today, has limited infrared capabilities. This is critical because when the light emitted by the first object reaches our telescope, it has already shifted towards the red end of the electromagnetic spectrum due to the existence of the universe. 

Expand the space between the objects, expand the space. Another key area will be the discovery of alien worlds. Eric Smith (James Eric Smith) said: Webb telescope project scientist. 

Scientists from 44 countries will be able to use the telescope, and suggestions include using infrared capabilities to penetrate supermassive black holes at the center of galaxies, including our own. 

“Limited only by our own imagination, scientists around the world will soon use this universal observatory to take us to places we have never dreamed of,” Smith said.
