What is the James Webb Space Telescope? the new marvel of space engineering

Tecnologiadelfuturo

It doesn’t matter if you are passionate or passionate about space and all that it hides. Or whether you like the world of technology more or less. When humans give birth a colossal and incredibly magnificent device like the James Webb Space Telescope, It is convenient to open your eyes and pay attention. Its development has a cost a quarter of a century of research, 25 years in which several generations of researchers have faced the most unusual problems of their careers. About 10 billion dollars invested to see what’s beyond what we’ve ever come to dream of.

You may have seen a documentary about James Webb, but rest assured that if what we tell you below is true, we don’t know if you will be. prepared for those we will see in a few months. We tell you everything we know about the most complex space telescope ever built!

Features of James Webb 馃

The James Webb Space Telescope It is not just, as we would say in the world of football, a change of position by position. It doesn’t mean putting a new Hubble into orbit because the other is already very old. This new ingenuity is so surprising that there are already those who say it 鈥渨ill do it revolutionize the idea we have of the Universe芦. And this, friends, is something very fat. Of course, before going into more detail on how it works, what are the main characteristics of this marvel of technology?

  • His Position, all a bold. If the Hubble Space Telescope is relatively close, just under 600 kilometers above our heads, the James Webb will greatly expand our horizons. Your definitive home will be in Lagrange point L2, Or what is the same, 1.5 million kilometers of our planet. This was one of the main problems of its development: everything has to be perfect, because once put into orbit … there will be no possibility of manual adjustments or repairs.
  • The James Webb telescopic mirror It is outrageous. While Hubble’s is 2.4 meters in diameter, James Webb’s main mirror is so large that it won’t fit any current launch vehicle. This has meant that it has to be broken down into six hexagonal sections which, when joined together, will reach the 6.5 meters in diameter. Crazy.
  • European components, much more than an economic contribution. Both files optical elements since the mechanical components of the NIRSpec spectrograph of the James Webb space telescope were manufactured by the German company Carl Zeiss in what was, without a doubt, the most special order received by this company in its entire history.

And now, let’s see how this behemoth works and what we expect!

How does it work? 馃

In fact, although there are those who sell it as a replacement for Hubble, it is much more correct to speak of natural succession. Why? Well, because the technology that James Webb incorporates, as well as the distance at which he will be, will allow scientists far more options than are available with the mythical Hubble.

To begin with, the new space telescope operates at wavelengths other than Hubble’s. That is, it will not see the same as its predecessor and the thing has its own explanation. While Hubble captures from the near ultraviolet, near infrared and visible spectrum, James Webb works from long-wave to mid-infrared visible light. This means that it will allow us see things we’ve never been able to see, and at a distance unimaginable until now.

The idea is that this new gadget, the most advanced in its field in history, will help scientists do that catches the light of the first stars. In addition to position of new exoplanets and the analysis of their atmospheres from afar to see if they would allow the survival of the human race will be another of its main objectives. The primary goal of the James Webb Space Telescope is to determine how it all originated and how we got to where we are today. An ambitious job like few others, of course, but thanks to it we will get it answers to questions that we may not have asked ourselves yet… And this is a real wonder.

It seems that everything is ready. The bolts and washers that gave the last scare are now properly tightened and in place. The device has passed all vacuum tests. Starts the countdown a throw that will mark a before and after.

James Webb telescope launch and operation 馃殌

It was expected that the James Webb Space Telescope was launched in 2007, no less than 14 years before its final launch date into orbit (if nothing else happens). And what is it that has delayed the project so much? I wish it had been a single problem … The truth is that the new James Webb telescope has suffered so far not less than 15 cancellations, and the reasons have almost never been repeated. Come on, what brought this to life was, like in the Jim Carrey movie, a series of catastrophic misfortunes.

But let’s go back to the beginning of time, why the development of this revolutionary mechanical device began no less than in 1996. At that time, to give you an idea, we were hallucinating with the Spice Girls and the Back Street Boys. The successor to the mythical Hubble telescope was such a titanic effort that, little by little, NASA had to host other space agencies in the project, yet the US government was on the verge of canceling it all in 2011, four years after it was supposed to be put into orbit and had exceeded $ 3 billion in investment.

Finally, with almost 10 billion dollars behind it and with the work of NASA, the European Space Agency and the Canadian behind it, the launch of the James Webb Space Telescope will take place. October 31, 2021. It was supposed to be March 30 this year, but the coronavirus affected the hours the engineers were able to devote to the project. It seems this time is the right time, we will have to be very attentive to these new eyes in space!
