NASA’s James Webb Telescope opens gold glass in space

Moving at a speed of a quarter of a mile per second in space James Web Space The telescope received its golden wings on Saturday in the final stages of its deployment since it was launched.

The most powerful telescope ever built was launched from French Guiana Christmas morning, But for the Ariane 5 to fit into the rocket the massive watch would have to be dead.

Webb’s 21-foot-wide main glass was folded in two places like two ears on either side of the human head. One of those ears, which has three hexagonal mirrors, opened on Friday, the last stage of which took place on Saturday morning when the teams placed the last three mirrors on the Starboard side. Now the telescope is in its final form to look back on Within the universe.

It was a major milestone at every step of the international team and deployment responsible for the mission and launch. The Web is a global initiative between NASA, the Canadian Space Agency and the European Space Agency.

NASA’s Chief Scientist Dr. Thomas Surbuchen appeared on NASA’s live broadcast on Saturday with a beard growing. Normally shaved Surbuchen said after the introduction of the web that he told his wife “I’m not going to shave until the web is fully used up”.

Since launched, the telescope has slowly expanded itself into space. A big step took place earlier this week when Webb opened the five-tier sunshade. Each layer should be tensioned before the next.

Then, the secondary glass attached with three long arms was brought out to the front of the spacecraft. Lee Feinberg, component manager of the Webb’s Optical Telescope at NASA’s Goddard Space Center, called it the “most sophisticated tripod in the world.”

Saturday’s deployment of the primary glass is the largest mirror ever in space with both wings open, and the telescope has completed every important step to open it from its missile. One hundred and seventy-eight Release instructions Webb must be disconnected to fully deploy. On Saturday, the final latches were released.

The deployment team at the Space Telescope Science Center, a control center in Baltimore, checked all the steps before the final mirrors opened and listened to the 1970s congestion. At one point, I was able to hear Anita Ward’s “Ring My Bell” through a NASA livestream.

Telemetry from the spacecraft was translated into animation showing the wings coming into place just as they did in space.

When the final three mirrors were combined with the large gold telescope, a voice in the control center confirmed, “We have reached the end of the deployment.” Everyone in the control center clapped and cheered.

The Web will continue to travel in space for the next two weeks to reach its final orbit at a distance of 1 million miles from Earth, known as Second Lock Range Point or L2. The spacecraft still has about 230,000 miles to go in its journey. It is expected to arrive by the end of January.

The James Web Space Telescope was launched on December 25, 2021, at the Guyana Space Center in Guerrero, French Guiana, with the Ariane Space 'Ariane 5 rocket.

The next five months will be spent Cooling the telescope, Aligning the 18 individual glasses that make up the primary glass and measuring scientific instruments.

NASA’s Goddard Space Flight Center has a website that tracks Webb’s progress. It offers distance, speed and temperature updates.

By design, JWST has a “cold side” and a “hot side”. The hot side is the base of the spacecraft’s tennis-court-sized solar shield that protects the heat sinks from facing the sun and operating at cooler temperatures.

The cold side covers the giant hexagonal glass of the heater and can sometimes be as low as 467 Fahrenheit. This posed an engineering challenge to heat-generating groups because the telescope had to operate at sub-freezing temperatures in space, but it was built at room temperature on Earth. To ensure that everything was working in space, the engineers placed all the mirrors and instruments through a cryo-vacuum test at NASA’s Marshall Space Flight Center in Alabama.

The $ 10 billion JWST will create the impressive legacy of the Hubble Space Telescope but is very powerful. The web looks back at the first galaxies in infrared light, discovering new worlds and solving unanswered questions about how we got here.

“Even five years from now, can you imagine how classes around the world would be affected by the telescope now being set up?” Zurbuchen said.

JWST can operate longer than its estimated 10-year lifespan and change what we know about the universe. The next generation of scientists will benefit from this work.
