    US and European officials have confirmed 24 December for the launch of the James Webb Space Telescope (JWST).

    Engineers completed final checks on Friday before closing the observatory behind the nose cone of its Ariane rocket.

    Everything is on track now for a lift-off from the Kourou spaceport in French Guiana next Friday at 09:20 local time (12:20 GMT).

    Webb is the $10bn (£7.6bn) successor to the Hubble Space Telescope.

    The new observatory has been designed to look deeper into the Universe than its predecessor and, as a consequence, detect events occurring further back in time - more than 13.5 billion years ago.

    Scientists also expect to use its more advanced capabilities to study the atmospheres of distant planets in the hope that signs of life might be detected.



    The US space agency Nasa, which leads the Webb project, and its partner the European Space Agency (Esa), released pictures on Saturday showing the moment of Webb's encapsulation.

    The giant fairing that will protect the telescope as it climbs through the atmosphere was lowered into place with the aid of guide lasers.

    The pictures are the last we will see of Webb and its golden mirrors on Earth. The next time we'll get a view of the observatory that has taken 30 years to design and build will be when it comes off the top of the rocket at the end of its 30-minute ascent.

    Video camera has been installed on the Ariane to show the telescope moving away into the distance to begin its mission. Engineers had put the launch on hold for a few days while they investigated a troublesome communications cable carrying data from Webb to ground-support equipment. Once this was fixed, the final "aliveness" tests on the telescope's subsystems could be run.

    Thomas Zurbuchen, Nasa's director of science, said the joint US-European team working on getting Webb ready would continue to be cautious right up to the moment of launch.

    "We're not taking any risks with Webb," he told reporters on Thursday. "It's already risky enough the way it is. We're absolutely making sure that everything works."

    Arianespace, the French company that manages operations in Kourou, will hold a launch readiness review on Tuesday. Assuming no issues come up, the Ariane vehicle, with Webb bolted on top, will then roll out to the pad.

    The rocket will have a half-hour window in which to get off the ground on Friday.

    If bad weather or minor technical issues intervene, there are launch opportunities on 25 and 26 December, after which teams would have to stand down for a day to allow production of hydrogen and oxygen propellants at the spaceport to catch up.

    "We reproduce the oxygen and the hydrogen on the spot and we have the capacity for three full fillings [of the Ariane rocket]," explained Daniel Neuenschwander, the director of space transportation at Esa.

    The Ariane carries a number of modifications for the upcoming flight.

    In particular, special vents have been put in the sides of the nose cone fairing to ensure there is an even loss of pressure during the climb to orbit. This will ensure there is no abrupt change in environment that might damage the telescope when the fairing panels are discarded.

    The rocket will throw Webb on to a path that will take it to an observing station some 1.5 million kilometres from Earth.

    This journey should last a month, during which time the telescope will unfold its 6.5m-diameter primary mirror and the tennis court-sized shield intended to protect its observations of the cosmos from the Sun's light and heat.




    Webb's goal is to image the earliest objects to form after the Big Bang. These are theorised to be colossal stars, grouping together in the first galaxies. Webb will also probe the atmospheres of planets outside our Solar System - so-called exoplanets - to see if they hold gases that might hint at the presence of biology. "Webb will have an opportunity to study these exoplanets and answer the fundamental questions that we astronomers ask ourselves, and the public alike - are we alone? Is Earth unique? Do we have other planets out there that can host life? These are very ambitious questions that speak to all of us," said Antonella Nota, Esa's Webb project scientist.

    • Nasa/Esa's James Webb Space Telescope officially set to launch December 24, 2021:

    NASA's newest flagship observatory is about to begin an incredible journey and now has an official launch date.

    The James Webb Space Telescope is expected to launch in a week, on Dec. 24 at 7:20 a.m. EST (1220 GMT or 9:20 a.m. local time in French Guiana), and has been packed up inside the nose cone of its Ariane 5 rocket for the trip.

    "Late yesterday, teams at the launch site successfully completed encapsulation of the observatory inside the Ariane 5 rocket that will launch it to space," NASA officials wrote in an update today (Dec. 18). The news comes as NASA and Arianespace, builder of the Ariane 5, worked to fix a data cable issue that delayed the mission from a Dec. 22 launch target.

    A final launch readiness review will be held Tuesday (Dec. 21) to make sure the Webb space telescope is ready for launch. If so, its Ariane 5 rocket will roll out to the launch pad at the Guiana Space Center in Kourou, French Guiana on Wednesday.
    Agency officials are framing Webb as a successor to the venerable Hubble Space Telescope, which means Webb has a big mandate to fill. Hubble's topline science includes showing the universe is accelerating in its expansion, finding new moons around Pluto, and helping to construct 3-D maps of dark matter.

    With the $9.8 billion Webb ready to pick up the baton after years of developmental delays, scientists expect the telescope will push even further back in time. The telescope will journey to an isolated spot about 1 million miles (1.6 million kilometers) from Earth known as a Lagrange point, a gravitationally stable spot between two celestial bodies.

    There, far from light interference from Earth, Webb will turn its attention to the early universe, to exoplanet atmospheres and other science using a fold-out telescope almost 22 feet (21.6 meters) across, roughly three times the aperture of the 1990s-era Hubble (8 feet or 2.4 meters). With more aperture available, Webb will gather more light and more detail on celestial destinations.

(Image credit: ESA)Webb has overcome numerous technical challenges, budgetary inflations and threats of cancellation over its complex development — including a last-minute unexpected release of a clamp band that pushed the launch by a few more days.
    The Atlantic notes the original project scope called for Webb to fly in 2007 with a budget of $500 million (roughly $667 million in 2021 dollars), but technology advances and unforeseen difficulties contributed to delays. (The pandemic also hurt the schedule in 2020.)

    This means Webb's budgetary trajectory also followed in the footsteps of Hubble, which launched over-budget and later than expected. Hubble is also famous for accidentally going to space with a flawed mirror, which required a crew of astronauts to repair. Webb will be too far for such help, but NASA has said prime contractor Northrop Grumman tested all systems thoroughly ahead of launch.

    The naming of the Webb telescope has also been criticized, reports indicate. The moniker is meant to honor James Webb, NASA's second-ever administrator who led the agency from 1961 to 1968 while it was preparing for human landing missions. Critics of the administrator claim that he was complicit in discrimination against gay and lesbian NASA employees during his tenure, including incidents such as the 1963 "immoral conduct" firing of Clifford Norton.

    But with the generational observatory finally on the eve of launch, NASA is hoping all the effort will be worth it. "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," the agency said in a November blog post about the mission. "Webb will reveal new and unexpected discoveries, and help humanity understand the origins of the universe and our place in it."

    • What to expect from NASA’s James Webb Space Telescope launch

    An anxiety-ridden launch that’s been decades in the making.

    On Christmas Day, NASA is gifting astronomers one of the greatest presents it can give by launching the most powerful space telescope ever created. Called the James Webb Space Telescope, or JWST, the space observatory is meant to be the successor to NASA’s Hubble Space Telescope already in orbit around Earth. And it promises to completely transform the way we study the cosmos.

    Sporting the biggest mirror of any space-bound telescope ever launched, JWST is tasked with collecting infrared light from some of the most distant stars and galaxies in the Universe. With this capability, the telescope will be able to peer far back in time, imaging some of the earliest objects to have formed just after the Big Bang. On top of that, it will unravel the mysteries of supermassive black holes, distant alien worlds, stellar explosions, dark matter, and more.

    it will unravel the mysteries of supermassive black holes, distant alien worlds, stellar explosions, dark matter, and more

    NASA has worked for nearly three decades to craft this telescope and get it to the launchpad. Now, the telescope is finally set to launch on top of a European Ariane 5 rocket out of Europe’s primary launch site in Kourou, French Guiana in South America, on Saturday, December 25th. But once the telescope is in space, there’s still a long way to go. Because JWST is so massive, it must fly to space folded up. Once in space, it will undergo a complex unfurling process that will take up to two weeks to complete. And this reverse origami must go exactly right for the telescope to function properly.

    All the while, JWST will be traveling to an extra cold spot located 1 million miles from Earth, where the spacecraft will live out its life, collecting as much infrared light as it can. It’s an extremely complicated launch and mission, with many opportunities for things to go wrong along the way. But if everything goes right, the world’s astronomers will have an unbelievably powerful tool at their disposal for the next five to 10 years.


    Read on to learn more about one of NASA’s most important launches of the decade.
    • The Impressive Specs:
    The first thing to know about JWST is it’s massive. The telescope sports a light-collectingmirror that’s more than 21 feet, or 6.5 meters, wide. For comparison, Hubble’s mirror is just under 8 feet, or 2.4 meters, across, and it’s been responsible for imaging some of the most iconic objects we’ve ever seen in the Universe. Thanks to its larger mirror, JWST will be between 10 and 100 times more sensitive than Hubble, allowing it to spot very faint objects in the sky.

    “You can sort of think of a telescope mirror like a light bucket,” Amber Straughn, the deputy project scientist for JWST at NASA’s Goddard Space Flight Center, tells The Verge. “The bigger the mirror, or the bigger the bucket, the more stuff you collect. And of course, in this case, the stuff is photons light from the distant Universe.”




    To assemble this massive mirror, JWST’s engineers had to build it in pieces. It’s made out of 18 hexagonal segments of the lightweight element beryllium, each one roughly the size of a coffee table. Together, the segments must align almost perfectly, moving so precisely they are aligned within a fraction of a wavelength of light, which is about 1/10,000th the diameter of a human hair.

    Each mirror has to match the other mirrors to a very small tolerance so that when they are aligned, they act as though they were a single mirror,” Lee Feinberg, the optical telescope element manager for JWST at the NASA Goddard Space Flight Center, tells The Verge.

    “they act as though they were a single mirror”

    One key feature of the mirror is that it is coated in a layer of gold about 200 times thinner than the average human hair. The gold is what allows JWST to see in the infrared — a type of light that is associated with some of the most distant galaxies and stars in the cosmos. Because the Universe is expanding, the farthest objects away from Earth are speeding away much more rapidly than objects that are nearer to us. The faster they sprint away, the more their light gets stretched, shifting away from the visible part of the spectrum and toward the infrared. With its gold mirrors, JWST should be able to see the infrared light from galaxies that are up to 13.6 billion light-years away from Earth.

    And that’s what makes the telescope a window into the past. Light from objects 13.6 billion light-years away will have taken that many years to reach the telescope’s mirror. Since we think the Universe is roughly 13.8 billion years old, that means these objects were around just 100 to 250 million years after the Big Bang.

    However, observing in the infrared is incredibly tough. Infrared light is associated with heat, which is emitted by everything with a temperature above absolute zero. JWST can’t live in our planet’s orbit or anywhere on the ground; the heat from Earth and its atmosphere would disrupt the observations. Even the telescope itself needs to be extra cold so that it doesn’t produce too much heat and throw off its own observations. That’s why JWST is being sent to a place 1 million miles from our world, known as a Lagrange point between the Earth and the Sun, where the pull of gravity and centrifugal forces are just right for the telescope to remain in a stable orbit. At this Lagrange point, JWST will stay at more or less the same distance and position from Earth at all times.



    Even at this faraway distance, heat from the Sun is still an issue. To stay extra cool, JWST is equipped with what is known as a sunshield. It’s made up of five ultra-thin layers of a material called Kapton, each the size of a tennis court stacked on top of each other. The outermost layer will always face the Sun and reflect most of its heat, operating at a scorching 230 degrees Fahrenheit. But each successive layer will be cooler and cooler so that JWST’s instruments stay nice and cryogenic, operating at about minus 370 degrees Fahrenheit.
    • A Troubled History
    JWST’sJWST’s journey to the launchpad has been long and bumpy. After years of discussion about what the next major space telescope after Hubble should look like, astronomers at the Space Telescope Science Institute formally recommended in 1996 that NASA build a new infrared space telescope with a mirror 4 meters wide. But NASA’s administrator at the time, Dan Goldin, decided 4 meters was not big enough and called on mission designers to increase the size to more than 8 meters.

    This decision made building the spacecraft way more complex. The massive mirror meant that JWST had to launch folded up since no rocket available was big enough to house the spacecraft in its final configuration. And the truth was the technologies needed to make the telescope a reality — such as the system and mechanics needed to perfectly align those mirrors — still needed to be invented.
    “The next stumble was that it’s way more expensive than we thought,” Thomas Zurbuchen, the associate administrator for the Science Mission Directorate at NASA, tells The Verge.

    “it’s way more expensive than we thought”

    Initially, astronomers hoped to launch JWST sometime between 2007 and 2011, for an estimated cost of anywhere from $1 billion to $3.5 billion. But over the decades, JWST’s costs continued to grow, while its launch date was pushed back and back. Eventually, lawmakers proposed canceling the project altogether over the snowballing budget. NASA then did a complete re-plan of the mission in 2011, and Congress agreed to continue funding the project while placing a budgetary cap on the telescope’s total life of $8.8 billion. A new launch date was set for 2018.


    But costs continued to increase while development stalled. Meanwhile, as engineers began piecing the telescope together and testing it to get ready for space, there were all sorts of issues. While the telescope was at Northrop Grumman, the primary contractor for the spacecraft, screws and washers seemingly came off the vehicle at one point, engineers found tears in the sunshield, and someone applied excessive voltage during a test, to name just a few errors. Eventually, in 2018,NASA settled on a final cost for the program: a whopping $9.7 billion to cover both development and the spacecraft’s operations in space. The agency also admitted that it wouldn’t be launching that year.

    New controversies arose over JWSTduring the telescope’s final stretch. Earlier this year, a group of astronomers raised concerns about the telescope’s namesake, James Webb, a NASA administrator during the Apollo program who oversaw the United States’ ambitious plan to put people on the Moon. In an article published in Scientific American, three astronomers called on NASA to rename the telescope, citing the fact that Webb was a high-ranking civil servant in the Truman administration during the Lavender Scare — when LGBTQ individuals were targeted and purged from the federal workforce. Ultimately, NASA decided not to rename the telescope after doing its own internal investigation and claiming it could not find evidence that Webb had been involved. However, the investigationwas criticized for not going deep enough.
    “There are no mistakes that are small on Webb that have small consequences. You have to be near perfection.”

    With its controversial name still intact, JWST was finally shipped to its launch site in French Guiana in October. On brand, its woes did not stop when it arrived in South America. The telescope’s launch was originally set for December 18th but was delayed twice due to a couple of mishaps, including a broken clamp band that sent unexpected vibrations through the telescope and an unforeseen communications issue between the rocket and its ground systems. The clamp issue was resolved, but the latter is still ongoing — though NASA claims it should not be an issue for launch.

    As Zurbuchen explains, every precaution has to be taken when a problem arises, no matter how small of an issue it might seem. The spacecraft has taken so long and cost so much to build that everything has to go right. Otherwise, the risk is a $10 billion telescope that’s dead in space.

    “Small mistakes... the vast majority of them have small consequences,” says Zurbuchen. “There are no mistakes that are small on Webb that have small consequences. You have to be near perfection.”
    • Launch Is Just The Start
    AsAs of now, JWST is set to launch on December 25th at 7:20AM ET. Its ride to space, the Ariane 5 rocket, has been Europe’s premier rocket for roughly the last two decades. In addition to being a highly capable rocket with a strong launch record, the selection of Ariane 5 also brings NASA’s European partners into what is considered a truly global mission.

    The launch itself should last roughly 26 minutes before JWST separates from the Ariane 5 rocket. While rocketing to space is always risky, there’s more anxiety to come when JWST is actually free from the Ariane 5. “Launch is really only the beginning,” says Straughn.
    • “Launch is really only the beginning.”
    If all goes well with JWST’s takeoff, that’s when the “29 days on the edge” — a term coined by NASA — begins. It’s an ominous phrase to describe the telescope’s complicated unfurling process. Once freed from the rocket and en route to its destination 1 million miles from Earth, the spacecraft will slowly unfurl and blossom like a mechanical flower.

    The first thing JWST must do right after launch is deploy its solar panel to start gathering energy from the Sun needed to power the entire spacecraft. During its next day in space, it’ll deploy its high-gain antenna needed to communicate with Earth. After that, the really wild reverse origami begins. JWST will change its shape and start to deploy its delicate sunshield, a process that is set to last for days. If that goes well, then the telescope will fully deploy its primary mirror.


    Even when the unfurling is done after about two weeks, JWST won’t be at its final destination — it’ll still have weeks to go. A little less than a month out from launch, the telescope will fire its onboard thrusters to put itself into its final position at its intended Lagrange point.

    Needless to say, a lot of astronomers, engineers, and scientists won’t be getting much rest until the entire thing is over. And there are plenty of moments where one failed pulley or one sticky actuator could jeopardize the future of the entire mission.

    But if everything goes right, then NASA will soon have some incredibly sharp eyes in the sky. The telescope will have to spend some time cooling down when it reaches its final orbit, and then engineers will need some months to test out all the instruments to see if they work properly. But JWST could be taking its very first breathtaking images as soon as this summer. For astronomers, the wait will be well worth it.

    “I really do think that this telescope will be transformational for astrophysics,” says Straughn. “I think that we will learn things about the Universe that completely surprise us, and that’s one of the most exciting prospects about any time we put a big, bold telescope like this into space. We learn things that we never expected.”

    • How to watch NASA's James Webb Space Telescope launch live online in several languages on Christmas Day
    Liftoff of NASA's new giant space telescope is set for December 25, 2021 at 7:20 a.m. EST (1220 GMT).

    NASA is counting down towards a Christmas Day launch for its biggest space telescope ever and you can watch it all live online.

    The James Webb Space Telescope is the successor to NASA and Europe's iconic Hubble Space Telescope. The next-generation capabilities of the upcoming observatory, paired with the laundry list of mission delays over the last several years, makes this a highly-anticipated event across the astronomical community. You can watch the entire mission on our live updates page here.

    The Webb space telescope is currently scheduled to launch no earlier than 7:20 a.m. on Saturday (December 25, 2021) from the Guiana Space Center in Kourou, French Guiana. On that day, you'll be able to watch one of several English-language virtual launch events on NASA Live, as well as Space.com, where we will also be streaming the telescope's flight courtesy of NASA TV. NASA will also broadcast the launch on Facebook, Twitter, YouTube, Twitch and Daily Motion. Live updates: NASA's James Webb Space Telescope launch

    The James Webb Space Telescope is installed atop its Ariane 5 rocket and awaiting payload fairing encapsulation ahead of its planned launch on December 25, 2021 from the Guiana Space Center in Kourou, French Guiana. (Image credit: Arianespace)NASA's launch coverage for the Webb space telescope begins at 3 a.m. EST (0800 GMT) on Saturday with an Ariane 5 rocket fueling update.

    Launch coverage begins in earnest at 6 a.m. EST (1100 GMT) and will include live views from Webb's Ariane 5 launch site in French Guiana, NASA's Goddard Space Flight Center in Greenbelt, Maryland and the Space Telescope Science Institute in Baltimore, Maryland, which is home to the space telescope's mission operations center.

    Alongside its English broadcast, NASA is hosting a Spanish-language Webb launch virtual event beginning at 6:30 a.m. EST (1130 GMT) on the space agency's website. Viewers can also watch via the social media accounts for NASA en Español like Facebook, YouTube and Twitter. This broadcast will be hosted by Begoña Vila, Webb instrument systems engineer, and will feature live commentary from Spanish-speaking members of the telescope mission.

    NASA will also air a clean feed without commentary from 7:00 a.m. until an hour after launch, according to a NASA statement describing the launch livestreams. There will be audio channels for launch commentary available, however, and will be provided in English, Spanish and French.

    NASA also maintains a Webb space telescope blog where launch updates will be regularly posted.


    Like Hubble, Webb is capable of taking incredible observations of the solar system and beyond. However its new observational responsibilities will mean that it will operate quite differently. Unlike the 31-year old Hubble mission, Webb will not fly through space in a place that is accessible for servicing. Space shuttle astronauts were able to service Hubble because it orbits about 350 miles (810 km) above the surface of the Earth. Webb, however, will be roughly 1,000,000 miles (1,609,344 km) from our planet.

    This vantage point will facilitate the operation of its scientific instruments, which in turn will help researchers learn about the many chapters of the universe's story. It is designed to observe the light from the early universe, revealing how the earliest stars and galaxies formed. It will also boost astronomers' understanding of objects closer to Earth, like exoplanets and objects within our solar system.

    Webb is born of an international collaboration that NASA is performing with the European Space Agency (ESA) and the Canadian Space Agency (CSA).
    --o-O-o--
    Nasa’s James Webb Space Telescope – inside the Ariane 5 rocket it will ride to space – has arrived at its final location on Earth: the Arianespace ELA-3 launch complex at Europe’s Spaceport located near Kourou, French Guiana. Webb is scheduled for liftoff at 7:20 am EST Saturday, Dec. 25. With Webb and its rocket securely on the pad, the team will run electrical diagnostics to ensure all lights are green for launch. Teams will power on the observatory while at the launch pad to run one final aliveness test to ensure all systems have power and are working before liftoff.




    Arianespace’s Ariane 5 rocket with NASA’s James Webb Space Telescope onboard, is rolled out to the launch pad, Thursday, Dec. 23, 2021, at Europe’s Spaceport, the Guiana Space Center in Kourou, French Guiana. The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 21.3 foot (6.5 meter) primary mirror. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe.
