This is the greatest true history of the James Webb Space Telescope. The launch of Webb is a historic moment that demonstrates the commitment, innovation and scientific ambitions of the United States Space Agency (NASA), the European Space Agency (ESA) and the Canadian Space Agency (CSA).
29 days after your vacation will be exciting and stressful at the same time. Thousands of components must work properly and consistently to unlock the Web and bring it to its final configuration when the Web flies into space to a destination nearly 1.6 million miles from Earth.
The largest and most complex telescope ever sent into space, the James Webb Space Telescope is the best use of technology. Due to various engineering considerations, Webb had to stretch as far as possible in orbit. Each phase can be managed by field technologists who give the Webb mission operations center complete control over unforeseen problems in the deployment process.
Story:
It is a scientific mission equivalent to the Apollo space shuttle, the International Space Station and the Hubble Space Telescope. For nearly two decades, thousands of people around the world have dedicated their skills to building the James Webb Space Telescope.
And it all comes down to that.
Once the James Webb Space Telescope is launched, we won’t get a second chance. We have 300 items that could go wrong and they should all work as expected. If the Web is a million miles from Earth, we can’t send anyone to fix it.
We have never launched such a large telescope into space. We want to observe the most remote regions of the universe that people have never seen before. Looking back nearly 14 billion years to observe the first galaxies formed after the Big Bang. And yet we want to look for the building blocks of life in the atmosphere of planets orbiting distant stars.
To reveal the history of the universe, we must first open the telescope. It is the largest main mirror, the largest canopy and the most powerful space telescope ever built. But the large telescope had to fit inside a 5.4-meter-diameter rocket screen.
This is the biggest hood of any rocket we need to fly into space. The Ariane 5 of the European Space Agency is one of the most powerful rockets in the world, which meets the screen size limitations.
We folded the Web, like origami, to the hood of the rocket. And this is the most difficult part of the mission that is spreading in space. This is what we do with modern scientific instruments with incredible accuracy. We know how to control a rocket, and within the next eight minutes the rocket blast sends it into space.
Tremble! Shot! Everything that is launched into space must pass through this environment and be ready to fly as soon as it gets there, and no one will come to fix anything.
Two weeks. This is the time it takes to fully deploy the Webb Telescope. It can take longer if needed, but two weeks after launch will be an exciting experience. It is the operations center of the Space Telescope Institute in Baltimore.
Two weeks after the launch there will be something like the World Cup, the Super Cup, you can choose the analogy yourself. Years of study are now applicable.
The Webb Observatory has 50 major attractions. fifty! It depends on how we classify it. And to stretch these 50 sections, you need to make 178 attempts. Each of them must be able to work.
The Webb extension is the most complex space activity we have ever undertaken. Again, there is nothing simple about Webb, we have never done anything like it.
Nothing happens just when we send something into space. We cannot do this without taking risks. This mission is right in the new realm of spacecraft.
The web is a perfect example of a passion for science that raises the power of technology to new heights. Webb’s unique designs are born from the most advanced engineering developments to achieve science’s goals.
Here is the plan.
Shortly after launch, we used all the solar panels on the internet as a power source and a mobile antenna for communication. About 12 hours later we had a large vehicle to bring Webb into orbit on the right track. Webb's destination is about 1.6 million kilometers from Earth, and this is where Webb will fulfill its scientific mission.
The web will move very fast. After orbiting the moon in a day and a half, about 50% faster than it took Apollo's astronauts to reach the moon's orbit. First we lower the cutter, then raise the main mirror and net tools for sun canopies. The solar wind will encourage us to stay in the sun. So we will open a trimmer component that will help us keep it stable.
The famous large segmented gold mirror will help us get new and incredible images of the universe. But in a sense, sunscreens are much more complex and just as important. Without sunscreen, Webb’s mission wouldn’t have worked. The area is about 2712 square meters, which is almost three tennis courts, five layers of canopy.
The very thin material of the hood with a thickness of about one thousand to two thousand inches supports them to get to where we want to be in conditions of "zero gravity", which is very difficult. The canopy protects the telescope from the heat of the Sun, Earth and Moon.
The concept may seem simple, but there is nothing simple in construction and operation, especially when we are in space. The Webb Sunshade assembly consists of 140 holes, about 70 hinge assemblies, eight spring-loaded splinter bearings, about 400 pulleys and 90 cables, for a total of 399 meters. This is all just to keep the visor under control when it is stretched.
First, a special flange that protects the sunscreen will be removed. They are passive at startup and will be fully functional when extended from the side. Next, we will lower the set of covers to the main area. As soon as this is the turning point, all 107 designs should work in the cube. 107! They shook five important layers for expansion during the deployment phase.
Unfolding sunscreen, proceed to adjust the optics. First, the secondary mirror will stretch and unlock, and a special heatsink behind Webb will also expand to further cool the device.
At the end we will open the main mirror, turn it over and unlock. When all this is done, Webb will move to the final stage of setup, but we are not done yet.
After 47 deployments, the most complex spacecraft deployment NASA has ever worked on, Webb is not yet ready for a scientific mission. During the repair of the fittings we will drive the car behind each of the 18 segments of the secondary Webb mirror and the sleek steering mirror located in the center of the main mirror.
We precisely align the mirror segments to form the perfect mirror structure. Only then was Webb ready to explore space.
