This is the world’s largest and most powerful space telescope. It showed its giant golden mirror on Earth for the last time on Tuesday. It was launched later this year and cost US$10 billion (about Rs 73,440 crore). An important milestone before the observatory.

NASA said that the 21-foot, 4-inch (6.5-meter) mirror of the James Webb Space Telescope was fully deployed and locked in place. This is a final test to ensure that it can travel millions of miles (1.6 million kilometers). Survive and get ready to discover the origin of the universe.

Scott said: “It’s like building a Swiss watch at a height of 40 feet… and preparing for this trip. We vacuumed in a vacuum of minus 400 degrees Fahrenheit (-240 degrees Celsius), which is better than the moon. Four times higher.” Willoughby of Northrop Grumman, chief contractor.

During his speech at the company’s spaceport in Redondo Beach, California, he will transport the telescope to French Guiana from there and launch it on an Ariane 5 rocket. NASA is scheduled to take off on October 31.

Weber’s primary mirror is composed of 18 hexagonal parts, coated with an ultra-thin layer of gold to improve its reflection of infrared light.

It will fly into the folded space like an origami, enabling it to be installed in a 16-foot (5 m) rocket fairing, and then will use 132 independent actuators and motors to bend each mirror to a specific position.

Together, these mirrors will act as a giant mirror, allowing the telescope to observe the universe more deeply than ever before.

Time machine
Scientists hope to use telescopes to go back 13.5 billion years ago and see for the first time the first stars and galaxies formed hundreds of millions of years after the Big Bang.

For this, they need to detect infrared light. Hubble, the most advanced space telescope at present, has limited infrared capabilities.

This is critical, because when the light from the first object reaches our telescope, it has moved towards the red end of the electromagnetic spectrum because the universe expands the space between objects as it expands.

Another key area will be the discovery of alien worlds. In the 1990s, the first planets orbiting other stars were discovered, and more than 4,000 exoplanets have now been confirmed.

Eric Smith, a scientist on the James Webb Telescope Project, said that Webb “has instruments that will propel this new and exciting field into its next epic of discovery.”

Scientists from 44 countries will be able to use the telescope, and its recommendations include using infrared capabilities to penetrate the supermassive black hole in the center of the Milky Way, including us.

Smith said: “Weber’s discovery capabilities are only limited by our own imagination. Scientists all over the world will soon use this universal observatory to take us to places we never dreamed of.”
