The Insane Technology Behind The James Webb Telescope!
With decades and billions in the making, James Webb Space Telescope is something that is a successor to amazing space technologies. The technologies that covered most yet not what the scientists exactly needed. Either they were not that advanced or they got into problems with time. James Webb Space Telescope had to be free of any trouble ever during its time in space. It can not afford to go wrong. It had to be perfect. But why does Webb have to be so complicated? Isn't it possible that a simpler task would probably be sufficient? Why spend billions of dollars and almost three decades in its making?
Welcome to Cosmos lab, your one station for all the news from space. Join us in today’s video to find out all about the struggle and the complex, never seen before technology of the James Webb Space Telescope.
When the Hubble Space Telescope was launched in 1990, it was clear that something wasn't quite right. The photographs it brought back to Earth were unsatisfactory, fuzzy, and far from what scientists had hoped for. The fault was traced back to the great mirror of the telescope, which had been improperly polished during production. To fix the problem, a rescue mission with a team of astronauts was dispatched. Hubble was fitted with 'glasses' to rectify its short-sightedness and transformed into an astronomical powerhouse that has since produced hundreds of iconic and scientifically valuable photos.
One of the most memorable photos in astronomy is the Hubble Space Telescope's first deep-field photograph. The image, which consists of a mind-boggling number of distant galaxies set against a blanket of black, was created from Hubble's scans of a small region in the constellation Ursa Major in December 1995.
Even though the Hubble was amazing, something was still missing. Astronomers were inspired by this timeless vision to start designing a new mission to investigate the early universe - one that would go back even further in time, to 300 million years after the Big Bang, when the first galaxies emerged. To accomplish so, the world's largest observatory, far larger than Hubble's 2.4 m mirror, was needed.
Scientists found their answers in the Next Generation Space Telescope (NGST) – a huge spacecraft with a 6.5 m segmented primary mirror that promised a whole raft of new discoveries. Excited by the NGST's potential, US astronomers quickly designated it as a top priority for space-based missions in the 2000 Decadal Survey, a wishlist of future projects compiled by the US National Academies of Sciences, Engineering, and Medicine. Pegged for launch in 2007 at a cost of $1bn, in 2002 it was renamed the James Webb Space Telescope after the former NASA administrator.
However, all the excitement and those dreams of a new telescope to study the evolution of galaxies, how stars and planets form and the answer of our creation quickly turned into a nightmare.
The project's budget escalated to the point where the US House of Representatives sought to terminate it outright in 2011, only for the troubled project to be saved at the last minute by scientists, the public, and the media. When the expense was poised to break the $8 billion barrier in 2018, the US Congress had to vote to provide it with more funds.
The JWST is now exactly $9.7 billion in cost. This is because, like the Hubble was rescued by the scientists, with the James Webb Space Telescope, rescue missions are impossible and therefore no failures are allowed. Part of the reason behind those skyrocketing costs was building a telescope of its enormous size.
Mark McCaughrean, senior advisor for science and exploration at the European Space Agency and interdisciplinary scientist at the JWST science working group, told Space.com that, James Webb Space Telescope is a prototype and with prototypes, you can always have something that goes wrong. That's why JWST is so expensive. Because we've spent two decades building and testing every single piece a million ways to do everything to make sure it doesn't have problems.
Engineering of the James Webb Space Telescope
How did we come up with the design for @NASAWebb? Join experts as they discuss the engineering behind the James Webb Space Telescope, the world’s largest and most powerful observatory.
Experts discuss how the observatory’s science goals drove its design and preview the complex series of deployments Webb will complete as it unfolds in space. This briefing took place at L-60, or 60 days before launch.
The James Webb Space Telescope, an international partnership with the European and Canadian space agencies, is targeted for launch Dec. 18. It will explore every phase of cosmic history – from within our solar system to the most distant observable galaxies in the early universe, and everything in between. Webb will reveal new and unexpected discoveries, and help humanity understand the origins of the universe and our place in it.

After 25 years and nearly $10 billion, the James Webb Space Telescope has finally left planet Earth. Billed as a successor to the beloved Hubble Space Telescope, the Webb’s mirror is six times larger and its instruments are tuned to observe longer wavelengths, in order to detect the stretched-out light from primitive galaxies 13.5 billion light years away.
That primary mission — to see the first stars and galaxies that formed after the Big Bang — determined the unusual and challenging design of the telescope. Instead of a shiny tube, the Webb Telescope looks like a giant honeycomb riding on a silver surfboard. The short answer to why it looks like that is: It needs to be very big and very cold.
In the video above, NASA astrophysicist Amber Straughn and Vox's Joss Fong build a small model of the telescope to explore its extraordinary design.

Things We’ve Never Seen: The James Webb Space Telescope Explores the Cosmos
#BrianGreene #NASA #JWST #UnfoldTheUniverse
The powerful James Webb Space Telescope--the successor to the Hubble Space Telescope--promises insight into profound questions that have dogged philosophers and astronomers for millennia. What is the origin of the universe? How are stars and planets created? Is there life elsewhere in the universe? Brian Greene brings together four scientists who will use the Webb to investigate these very questions: John C. Mather, NASA’s lead scientist on the project and a Nobel Laureate; Natalie Batalha, NASA’s lead scientist on the Kepler Mission, which discovered the first rocky planets outside our solar system; Adam Riess, who earned a Nobel Prize for his revelations about the expansion rate of the universe; and Ewine van Dishoeck, a Kavli Laureate for her pioneering work in the field of astrochemistry.

James Webb Space Telescope: How will it work? - BBC News
The BBC’s science editor Rebecca Morelle on how the observatory hopes to capture the history of our Universe.
The $10bn James Webb telescope has left Earth on its mission to show the first stars to light up the Universe.
The observatory was lifted skyward by an Ariane rocket from the Kourou spaceport in French Guiana.
Its flight to orbit lasted just under half an hour, with a signal confirming a successful outcome picked up by a ground antenna at Malindi in Kenya.
Webb, named after one of the architects of the Apollo Moon landings, is the successor to the Hubble telescope.
Engineers working with the US, European and Canadian space agencies have built the new observatory to be 100 times more powerful, however.

How The Golden Eye Of The James Webb Space Telescope Will See The Edge Of The Universe
NASA’s James Webb Space Telescope is a time machine to the early universe, which uses massive golden mirrors to capture ancient light. The results will likely rewrite and expand our textbooks for years to come.

An international project like this that has countless “firsts” takes time, but the painstaking effort to design, construct and test Webb’s optical system will be worth the wait. Overnight, the eye of the telescope will revolutionize our understanding of the cosmos and be set loose on the biggest questions in astronomy.
The astronomical community was after something that hadn’t been observed before… the early universe. The first stars and galaxies started to form 100 to 250 million years after the Big Bang, around 13.6 billion years ago. Because the universe is expanding, actually the light from the early universe gets stretched into the infrared and that's called a cosmological redshift. It's this cosmological redshift that Webb's optics will be hunting for, to uncover the story of the early universe. Infrared light can pass through dust in the universe. And so it allows us to peer through dust clouds and see, for example, stellar nurseries.
No other telescope today has the collecting power and sensitivity that NASA’s JWST has to lift the veil on the universe’s secrets. The James Webb Space telescope is sensitive enough that if there were a bumblebee at the distance of the moon, we would be able to detect it. The telescope’s core superpowers come from its advanced optical system.

Webb vs Hubble Telescope
“Webb often gets called the replacement for Hubble, but we prefer to call it a successor. After all, Webb is the scientific successor to Hubble; its science goals were motivated by results from Hubble.”
The Five Big Ways the James Webb Telescope Will Help Astronomers Understand the Universe
“The further into space scientists can look, the further back in time they can observe a galaxy. Webb, being the farthest seeing telescope yet, can root out the youngest looking galaxies humanity can observe.”
The Webb Space Telescope Will Rewrite Cosmic History. If It Works.
“The James Webb Space Telescope has been designed to answer many of the core questions that have animated astronomers over the past half-century. With a $10 billion price tag, it is one of the most ambitious engineering initiatives ever attempted. But for it to achieve its potential — nothing less than to rewrite the history of the cosmos and reshape humanity’s position within it — a lot of things have to work just right.”
The $11-billion Webb telescope aims to probe the early Universe
“If everything goes to plan, Webb will remake astronomy by peering at cosmic phenomena such as the most distant galaxies ever seen, the atmospheres of far-off planets and the hearts of star-forming regions swaddled in dust. Roughly 100 times more powerful than its predecessor, the Hubble Space Telescope, which has transformed our understanding of the cosmos over the past 31 years, Webb will reveal previously hidden aspects of the Universe.”

James Webb Telescope Will Make TERRIFYING Discoveries!
Decades after the idea, the James Webb Space Telescope has finally made it to space. Launched on this Christmas, the telescope started its deployment after it was sent to the space. Scientists are depending on the telescope to know the truth about our existence and also if there is any other life in this universe other than ours. The telescope fans are curious to know about its deployment and what’s next for this masterpiece, they are asking if the telescope is really going to find the answer to our creation? Welcome to Cosmos lab, your one station for all the news from space. Join us in today’s video to find out about the deployment of the James Webb Space Telescope, its goals, and what’s next for this massive beast.
The James Webb Space Telescope is the world's most powerful and largest space telescope. It is an infrared space observatory that launched on Dec 25, 2021, from ESA's launch site at Kourou in French Guiana, onboard an Arianespace Ariane 5 rocket. The telescope will let scientists to peek back 200 million years after the Big Bang to see how our cosmos looked. Images of some of the first galaxies ever formed will be captured by the telescope. It will also be able to peek inside dust clouds to see where new stars and planets are developing, as well as investigate the atmospheres of planets orbiting other stars. It will be able to observe objects in our solar system from Mars outward.
The $10 billion James Webb Space Telescope will explore the cosmos to learn more about the universe's history, from the Big Bang to the birth of alien planets and beyond. It's one of NASA's Great Observatories, huge space instruments that include the likes of the Hubble Space Telescope to peer deep into the cosmos.
After being launched on Christmas Day, the James Webb Space Telescope will journey over a million miles or 1.5 million kilometers to its permanent home, a Lagrange point — a gravitationally stable place in space. At the second Lagrange point, the James Webb Space Telescope will orbit the sun (L2). L2 is a location in space near Earth that is opposite the sun; this orbit will keep the telescope in alignment with Earth as it orbits the sun. Several other space telescopes have used it, notably the Herschel Space Telescope and the Planck Space Observatory. If Webb gets to the right zone, it can use a minimum of fuel to stay in place thanks to a near-perfect alignment with the sun, Earth and moon.
The new observatory, the world's largest space telescope, successfully unfolded its final primary mirror piece on January. 8, capping one of NASA's most challenging space deployments ever. After the deployment, Engineering teams cheered back at the Space Telescope Science Institute in Baltimore, Maryland as the National Aeronautics and Space Administration announced on Twitter that the final wing was deployed.
‘Final wing is now deployed! Short celebration, but we’ve still got work to do. Engineers are working to latch the wing into place, a multi-hour process. When the final latch is secure, NASA Webb will be fully unfolded in space.’
Webb's five-layered sunshield — a 70-foot-long, kite-shaped structure that acts as a parasol — was deployed to keep the telescope's equipment cool so they could detect tiny infrared signals from the remote reaches of the Universe. The sun shield will be permanently installed between the telescope and the Sun, Earth, and Moon, with the Sun-facing side designed to resist temperatures of up to 230 degrees Fahrenheit (110 degrees Celsius).
The telescope was folded up because it was too large to fit into the nose cone of a rocket in its working condition. According to Nasa, unfurling has been a sophisticated and difficult process - the most difficult of its kind ever attempted. However, it has now been successfully deployed and according to NASA officials, we have still got work to do.
So, what is this work, and what is next for this gigantic space telescope? Webb is expected to arrive at its insertion location by Jan. 23. John Durning, Webb's deputy project manager at NASA's Goddard Space Flight Center, after the deployment in a press conference from Webb's control center at the Space Telescope Science Institute in Baltimore, Maryland, said to the reporters that,
‘As Webb prepares for the engine fire, team members will spend the next 15 days aligning the 18 mirror segments to essentially perform as one mirror.' I should say also, that Webb will start turning on the instruments in the next week or so, Durning added. And then after we get into L2, as the instruments get cold enough, they [engineers] are going to be starting to turn on all the various instruments.’
L2 is an excellent area for Webb to carry out its mission.

James Webb Telescope Terrifying Discoveries Will Change Everything!
The James Webb telescope has been conceptualized for more than a decade. Its fans would be happy to hear that it has finally been launched into the dark abyss known as space. It was launched last christmas, and it began its deployment immediately after it entered space. We hope that this telescope would allow us to know a lot more about both our existence, and the possibility of external life outside us.
Since the launch of this $10 billion telescope, its fans have asked nonstop about its progress, and if it really will do what it was set out to do. Join us as we explore all the possibilities of this telescope and give some insight on how this telescope will finally make terrifying new discoveries.
If you’re interested in space travel, you should know that there are a lot of limitations to this particular concept, one of which is the ability to view planets and stars past our solar system. It was even a challenge to view events occurring past mars due to the absence of light. Astronomers, engineers, and astronauts have dreamed of being able to see past our solar system. Now, the James Webb telescope is capable of making it possible.
For those who don't know, the James Webb telescope was designed to the largest telescope ever created. It got launched on December 25th last year from the ESA space site at Koolu via an Arianespace Ariane 5 Rocket. If this telescope performs its purpose, it would allow us to be able to take a look at the events of the big bang. Imagine seeing how the events occurred during the big bang which happened as far back as 200 million years ago.
We would be able to view the first galaxies that were born out of the big bang, and also look at any new planets or stars developing. This would be a phenomenal achievement, and would be such good news for science.
Its journey spans over a million miles to a gravitationally stable point in space. Arriving at that point in space would keep it from leaving the solar system, and will keep it stable enough to take a look at several galaxies. The telescope would then land on a second gravitationally stable point, L2. L2 is a position in space that is in close proximity and alignment with earth and is directly opposite the sun. At this point, it will be able to orbit the sun even more closely.
Interestingly, other telescopes have used this particular area at several points in time and have captured mind-blowing information. If it gets to this point perfectly, it would use the gravitational stability of that point as well as minimum fuel to stay in perfect alignment with the sun, moon, and the earth.
Its successful launch from the earth took about 31 minutes, and scientists, engineers, and fans from all over the world cheered all the way through. We know you might be wondering how its going to survive the full force of the sun. The telescope’s designers understood this, and built a 5-layer, 70-foot long sun shield. It keeps the equipment of the telescope cool and prevents the telescope itself from getting destroyed due to the heat from the sun.
This sun shield has been checked and given the okay by multiple engineers and scientists from around the world due to its ability to protect itself from temperatures of up to 250 degrees Fahrenheit. If you’re watching the video, you would probably notice that the telescope is way bigger than a rocket can fit. Because of that, it was designed in such a way that it can be folded up and safely transported in a rocket. According to NASA, opening it up has been one of the most sophisticated processes they have undergone. What’s more is that the process isn’t over yet, as they have said they still have some work to do.
Although this telescope has not arrived at its destination yet, it is expected to arrive by January 23rd. The deputy project manager at NASA’s space flight centre said in a conference that between the start of January and the 23rd, the team would spend its time aligning the 18 mirror segments in order to successfully form one giant mirror.
Beryllium was used to produce these mirrors because it is a lightweight metal, and it is fairly resistant to the sun’s rays.
After it has been fully unfolded and assembled, its different compartments will be turned on. The engineers believe that this will happen between 7-14 days.
The distance from the sun ensures that enough darkness is gotten for the heat seeking infra-red studies to be performed. These infra-red telescopes would allow the telescope to view distant galaxies, stars, and planets.
This telescope will be the most powerful telescope ever created, and it has already started breaking records. It surpasses the capabilities of the hubble space telescope, among many others.
NASAs Golden Eye: The James Webb Space Telescope Explained
Its sunshield is as big as a tennis court, it's covered in gold and can see light that has travelled for 13 billion years. But NASA's James Webb Space Telescope has also had a troubled history. Here's why this powerful space observatory is a game changer.

The SCARIEST Thing About the James Webb Telescope #shorts
What is the Scariest thing about the James Webb Space Telescope? It's Not what it's going to see, it's where it's going to be!
When it launches on December 22, 2021, a rocket is going to send the telescope about one million miles (1.6 million km) from Earth. That's 4 times farther away than the moon. It will be stationed too far from Earth for astronauts to reach.
Whereas the Hubble Space Telescope had many visits from astronauts to service, the James Webb telescope will need to run perfectly from the get-go.
The telescope will have a fuel supply that should keep it stable in orbit for 10 years.
Planning for this scope began over 20 years ago, let's hope for the best!
James Webb Telescope Terrifying Discovery Before Big Bang Will Change Everything!
How did this universe begin? Were we alone in this huge cosmos before the
Big Bang? Just some of the numerous questions that scientists have been
pondering for years, like this one: They planned a slew of projects and
missions to gather as much information as possible about our origins and the
universe we live in, but no technology existed to do it. The James Webb
Space Telescope, a large telescope was then built by scientists and is
expected to help us understand the origins of the cosmos.
The projected Christmas Day 2021 launch of the $10 billion James Webb
Space Telescope was both exhilarating and worrisome for the thousands of
scientists, engineers, managers, and support staff who worked on the project
for almost a decade. The scientific potential of the JWST is vast, and it could
provide answers to some of the most fundamental problems in the universe's
evolution. But the real question is, can this JWST achieve it? Is it possible that
James Webb will be able to see thousands of light-years into the future? We'll
be discussing this in today's video.
But before we begin, kindly subscribe to this channel, like this video, and
enable the notification feature If you haven't already. Come on, let's get
A new era of astronomy is just around the corner, provided everything goes
according to plan. After a nail-biting launch on Christmas Day, the James
Webb Space Telescope (JWST) has launched its mission to capture the birth
of the universe. James Webb Space Observatory will be NASA's largest and
most powerful space research telescope, exploring the cosmos to learn more
about the universe's history, from its Big Bang to the birth of alien planets
and beyond. The observatory will cost $10 billion. It is a part of NASA's Great
Observatories, which comprise the Hubble Space Telescope and other
massive space telescopes that can stare into the universe.
One of JWST's primary goals is the exploration of galaxy formation more than
13.5 billion years before the Big Bang, a hitherto unobserved period of
cosmic history that formed our universe as we know it today. According to
NASA, JWST was built to observe a time in the universe's history that has not
yet been observed before, rather than to study the origins of the cosmos.
We prefer to think of the JWST as a successor to the Hubble Space
Telescope, rather than a replacement. More than 30 years after its launch,
the Hubble Space Telescope has provided us with breathtaking views of the
universe and countless scientific discoveries. It is our hope and expectation
that it will continue for many more years to come.
However, the telescope's 2.4-meter diameter mirror, compared to ground-
based telescopes, limits its sensitivity and ability to observe the faintest
objects. This is a limitation. Even though Hubble can observe infrared light, it
cannot access the light wavelengths from the very first stars and galaxies.
Hubble has some capability to observe infrared light. JWST, on the other

Knowing when and how the first stars originated soon after the Big Bang is
an important scientific subject and one of the key science aims of JWST.
Carbon, silicon, and gold, which are essential to life and contemporary
technology, were produced in the early stars, but how they did so is still a
mystery to us.
As a result, the design of this observatory has been influenced greatly by the

It's not just the initial stars and galaxies that will be studied by JWST.
Researchers from all over the world can apply for time at this observatory,
which is designed to serve a variety of purposes. Infrared observation will
allow JWST to see through the clouds of dust that enshroud very young stars,
which are impenetrable to the visible light of the telescope.
That means it will be able to see directly into star-forming regions,
something Hubble hasn't been able to do yet. The findings will provide light
on the formation of stars and the systems of planets that orbit them as a
result of the collapse of dust and gas clouds.
Webb will be able to see further into the universe than Hubble, and it will be
far more sensitive. This will allow Webb to go back much further in time and
view the earliest galaxies that formed in the early universe, according to
How James Webb Telescope Will Detect Life In The Universe
How James Webb Telescope Will Detect Life In The Universe.
The James Webb Telescope is fitted with some mind-blowing technology that is decades ahead of its predecessor, the Hubble telescope. NASA has even added what they are calling their “secret weapon” aboard the telescope that they believe will help detect alien life in our universe. After years of delays and tweaking, the telescope is finally hurdling through the cosmos, ready to observe and collect data in ways that have never happened before.

Revolutionary James Webb telescope blasts off into space | DW News
A revolutionary telescope has been launched into space, marking the beginning of a new era of scientific exploration.
The James Webb telescope - named after a former head of NASA - lifted off on board a rocket from the European Space Agency's launch base in French Guiana. The launch is the culmination of several decades of work by European, Canadian and US space agencies. It's being hailed as the world's most powerful telescope.
The James Webb is expected to beam back new clues about the origins of the universe.
The new eye in the sky is the successor to the legendary Hubble space telescope. Its six and a half meter mirror makes the Hubble look tiny by comparison.
The James Webb, the biggest telescope ever sent into space, is made up of 18 segments plated with a razor-thin gold coating. The instrument has to be folded up to fit into the rocket’s nose-cone. The telescope will scan the heavens using long-wave infra-red light.
Astronomers will be able to look back towards the Big Bang nearly 14 billion years ago. Back to the origins of the universe and the formation of the first stars and galaxies.
The new telescope could also prove decisive in the search for extra-terrestrial life. It can probe so-called exo-planets. Nearly 5000 have already been discovered orbiting distant suns. The James Webb will monitor how exo-planets move in conjunction with the stars.
Transits like these mean it can take a virtual fingerprint of the atmosphere of these remote worlds – and assess for the first time whether they hold the building blocks of life. Before the research can begin, there will be a delicate two-week operation in which the telescope has to unfold itself.
Never before has a satellite been launched with so many moving parts, and nothing can be allowed to go wrong. And it will be six months after the launch, before the telescope is ready to gather its first scientific data.

James Webb Just Completed the Most Difficult Task of its Mission
The iconic James Webb Space Telescope has completed the most challenging task of its mission: deploying the massive sunshield. The giant kite-shaped and tennis-court-sized sunshield is now sailing in full bloom towards Webb's final destination.
It started with the unfolding of the two pallet structures: forward and aft. This resulted in bringing the observatory to its full length of 70-feet. Then, the Deployable Tower Assembly separated the telescope and instruments from the sunshield and the main body of the spacecraft, thereby creating room for the sunshield to fully deploy. Following this, the aft momentum flap and membrane covers were released and deployed. The mid-booms deployment allowed the sunshield to extend to its full width of 47 feet. Finally, on January 4, 2022, at approximately 11:59 a.m. EST, the sunshield was fully tensioned and secured into position. This marked the completion of the intense task of sunshield deployment.

«James Webb Space Telescope» startet in den Weltraum | WELT LIVE DABEI
Nach jahrzehntelanger Planung, Kostenexplosionen und mehrerer Startverschiebungen soll das bislang größte und leistungsfähigste Teleskop der Raumfahrtgeschichte am Samstag (13.20 Uhr deutscher Zeit) ins Weltall aufbrechen. Das «James Webb Space Telescope» (JWST) - eine rund zehn Milliarden Dollar teure Kooperation der Weltraumagenturen der USA, Kanadas und Europas - soll an Bord einer «Ariane»-Trägerrakete vom Weltraumbahnhof Kourou in Französisch-Guayana starten.
Bis zum Zielorbit in 1,5 Millionen Kilometern Entfernung soll das JWST rund vier Wochen unterwegs sein. Erste Daten und Bilder des Teleskops werden frühestens im Sommer erwartet.
Das JWST soll Nachfolger des «Hubble»-Teleskops werden, das seit mehr als 30 Jahren im Einsatz ist. Es soll unter anderem mit Hilfe eines 25 Quadratmeter großen Spiegels Bilder aus dem frühen Universum liefern. Wissenschaftler erhoffen sich davon neue Erkenntnisse über die Entstehung unseres Universums. Die Lebensdauer von «James Webb» ist erstmal auf etwa zehn Jahre angelegt.

James Webb Space Telescope: 5 Critical Events That Will Determine The Success
Commercial Purposes ► Lorenzovareseaziendale@gmail.com
The James Webb Telescope will be one of the hardest technical mission NASA will ever attempt. Despite the numerous delays, technical challenges, funding crisis and uncertainties the Mighty James Webb Telescope was launched on December 25. But The launch itself does not guarantee the success of James Webb . After decades of development it all comes down to 5 critical steps that will determine whether this 10 Billion dollar project of NASA will succeed or not.
5-) The Ariane 5 Launch- This is obviously one of the most important event in the journey of the James Webb Telescope.
4-) Separation and Solar Array Deployment- Occurring 30 minutes after the Launch, deploying the solar array is another critical process.
3.) Full sunshield deployment- After the deployment of the support structures another very critical step is the Sunshield deployment. If it fails, or if the tensioning catches or snags, the telescope will not cool, resulting in a catastrophic loss.
2-) Mirror Deployment- The anxiety of sunshield deployment will not go away soon. Six days into the trip, the telescope's secondary mirror will be lowered into position at the end of three long arms.
1-) L2 Orbit Insertion- The final and an important event is the L2 Orbit insertion. After all the 4 critical moments it will boil down to this final event, which will determine the position of James Webb. After the first 29 days, JWST will be 1,400,000 kilometers away from Earth, almost to its final destination of the L2 lagrange point.

How long it will take to see the first images from webb telescope?
Webb's deployment in space involves unfolding the sunshield and mirrors and that took almost a month before reaching its destination.
After reaching its orbit, webb undergoes science and calibration testing. That means, the commissioning of this telescope will take about six months.
The commissioning of this telescope is one of the most complex operation in the space.
Then, webb will deliver its first images and study infrared light from celestial objects with much clarity than hubble or any other telescopes.
With the james webb telescope, astronomers are looking back farther than the hubble, to the formation of the universe's very first galaxies.
