NASA’s golden mirror allows you to look beyond the worlds

Imagine a mirror that allows you to look at distant worlds and beyond. It ‘s not just a magic mirror. NASA is preparing to launch a telescope into space that can look at the stars with the help of a 18-piece mirror covered with a thin layer of pure gold, NASA’s golden mirror.

Consisting of NASA’s golden mirror

NASA’s golden mirror made of beryllium, a rare, strong and lightweight metal. The pure gold layer is used to give the telescope maximum reflective power. Its height extends 21 feet.

The telescope will not need  powered by launch in L2, one of five points where gravity balanced between the sun and the earth in a way that allows the telescope to remain in a fixed location.

It is expected that this telescope which called “Web” launched in 2020

The Web expected to  launch in 2020, a $ 8.8 million project that will provide a new perspective on the universe. The director of the optical telescope at NASA’s James Webb Space Observatory, Lee Weinberg, “It will solve the mysteries of our solar system, and we will be able to look at distant worlds around the stars and beyond, as well as their ability to look at the mysterious structures and origins of the universe, and our place in it.”

The telescope designed to serve as a model with greater capabilities than its predecessors

The telescope designed to serve as a model with greater capabilities than its predecessors, the Hubble Space Telescope launched in 1990. Unlike Hubble, which orbits the Earth at 340 miles, the Web sent a million miles into space.

in addition to, The size of the large mirror aims to increase clarity of detail, as “the larger area works to gather more light,” according to Weinberg.

In addition to,

As for the shape of the hexagonal pieces, Weinberg explains that he helps the mirror fold in order to carry it on a rocket when launched into space.

On some of the difficulties they might face in space, he said it would take two months just to open the telescope, cool it, and collect all the pieces correctly.

And also, to collect the pieces as if they were one huge mirror, it meant that each piece ” accurately incorporated up to 1 / 10,000 of human hair thickness,” according to Weinberg.

How to protect NASA’s golden mirror from high temperatures

The site’s low temperatures will increase, Where the Web is to be able to give a clearer view of space, The mirror needs to remain very cool to avoid emitting any heat that may interfere with its observations, because it uses infrared to look at the universe unlike Hubble, which uses visible light.

To protect it from the heat of the sun, the telescope will provide a 70-foot solar windscreen, equal to the length of a tennis court, made of heat-resistant material that keeps the mirror at temperatures of 370 degrees Fahrenheit, equivalent to three times the coldest recorded on the planet.

Finally,

NASA  already finished building the Web, but its launch delayed several times to conduct further tests to avoid the failure of the Hubble launch in 1990 because of errors in the testing phase that led to the telescope’s capture of unclear images.

It took three years, an 11-day mission and a total of 35 hours of walking in space to fix the error.
