The most expensive scientific and space construction project has been put into orbit


On December 25, the most expensive instrument and long-term space construction in the history of mankind, the James Webb telescope, which is called one of the most important scientific programs of our time, was launched into Earth's orbit. The telescope was built for almost a quarter of a century, about $ 10 billion was spent on it, and after numerous launch transfers it was successfully launched by the carrier rocket Ariane 5 from the Kourou cosmodrome in French Guiana.


James Webb is a joint venture between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA). NASA invested $ 8,8 billion, ESA - $ 815 million, including the cost of the launch vehicle and launch, CSA - $ 165 million. A telescope weighing 6350 kg was created in the United States with the help of scientists from 17 countries.

After separation from the LV, the telescope independently headed for a halo orbit at the L2 Lagrange point of the Sun - Earth system. It will move there for about a month, and then it will begin to revolve around the Sun along with the Earth. It will be located at a distance of 1,5 million km from the Earth on the opposite side from the Sun. Then it will take 5 months to adjust the optics and calibrate the equipment. Only after this it will become clear whether the hopes of scientists will come true or not.

James Webb should eventually replace the Hubble Telescope, which was launched in 1990 and is scheduled to be decommissioned in 2030. The design life of the new telescope is 10 years (the coolant supply will be enough for about that much). James Webb is about 100 times more sensitive than Hubble, which operates primarily in the optical and ultraviolet ranges and orbits the Earth much closer - about 550 km - entering and exiting our planet's shadow every 90 minutes.


The diameter of the folding (composite) main mirror of James Webb is 6,5 m, it is assembled from 18 beryllium segments of a hexagonal shape, covered with a thin layer of gold (has a good reflectivity), which is much larger than that of Hubble - 2,4 m. The new telescope can operate in the infrared range, which makes it possible to study distant galaxies, making it the most powerful tool in the hands of astronomers. Scientists will be able to look into the deep past of the Universe, see the formation of the first galaxies and the light that just appeared after the so-called Big Bang of stars.

In addition, the telescope will provide an opportunity to assess whether there is life on the moons of Jupiter and Saturn, and will also look for potentially habitable planets. The new telescope will observe light sources at wavelengths from 60 to 500 microns in the infrared spectrum. It will be able to focus light at distances of over 13,5 billion years. The telescope will also investigate relatively cold exoplanets, supermassive black holes and answer some scientific questions.

    Now they will show cartoons through it. Why weren't Russian missiles entrusted with launching?

      Because Russian missiles are like a cartoon themselves) just kidding.
      In fact, it's cool - for 10 lard bucks to make a fotik for new beautiful screensavers and backgrounds on your desktop - I'm looking forward to it.
      Practical use - no, it's like showing pictures of bananas to monkeys in a zoo, sorry astrophysicist colleagues)

        Your development perspective is not far from those of those zoo monkeys.

    James Webb Space Telescope developed since 1996. Pit was originally estimated at $ 500 million... However, the project soon turned into a financial black hole as constant design changes and technical challenges increased the cost of the telescope to $ 10 billion. At one time, the JWST came close to being canceled by the US Congress.

    What is characteristic of the critics of Roscosmos in the comments is not visible request , probably they ran to put a candle for Rogozin's health laughing And they obviously do not want to tell that this is different and what kind of cut. winked

      And nevertheless, it was built and launched, it will bring invaluable benefits to humanity ... if it were a Roscosmos project ... it would have fallen upon launch.

        O!!! The first classic podpenguinovik arrived in time. Everything is as usual, everything that needs to be understood and forgiven from them, but we would probably have ruined everything. sad
        What amazing logic. Well then, catch it. If you were a normal person, I would discuss the topic, but watch the video and go to the Americans to heal the wound under the coccyx fellow

          You are a comrade with strange fantasies.
          This telescope is really cool, you compare it to the spectrum? Well, the spectrum is also an international project, and not exclusively Russian.

            You are a comrade with strange fantasies.

            if it were a Roscosmos project ... it would have crashed on launch.

            In my opinion, you are fantasizing here. And I show you the facts, the "project" flies and works. And in general, Roskosmos does not often fall, for the last 3 years everything is so good with this.

            This telescope is really cool, you compare it to the spectrum?

            What criteria do you use to determine what is "cool" and what is not? Really by country of origin? I showed you the video for a reason. The man is a professional and he is happy as an elephant. It looks like he disagrees with you.

            Well, the spectrum is also an international project, and not exclusively Russian.

            Have I argued otherwise? Moreover, these projects have much more in common, including the long term of the project. By the way, this is also in the video.
            But for some reason, you spit into a Russian project, and pray for another, describing what invaluable benefits it will bring to humanity.

        No, it would have been built for another 30 years. Such a cut is gorgeous.

    "Ale, Vasek? Do you hear, I got sick of Kolya's gift to look for! Yes, there was. Yes, this is not an auction, shit in kind! The picture wanted to buy - it turned out to be cheap, Vrybel. The vase - so finally Chinese. And old stuff, before our era. What "I don't know" ?! Are you the manager or where? I why the hell are you crying? You will go to sweep the streets !!! So, by the way, find a present. and so that the American was! Digital, with good optics. And with remote control! "

    According to information agencies, today in the morning an anonymous person from Russia bought the Hubble orbital telescope.

    Well done ;: telescopes are robots, and a helicopter is already flying on Mars! And we will continue to jump on a trampoline with a cattail! ?

    Well. Good luck.
    Telescopes are essential for development.

    By the way, today is supposedly the last day of the "window" for Angara Rogozin. We wait.
