James Webb Space Telescope launched – check it out with us

Begins James Webb Space Telescope It will take place on December 25 after 1:20 pm Poland time atop an Ariane 5 rocket from the Kourou space base in French Guiana. Scientists expect that it will be real scientific revolutionIf the mission was successful. We can also witness an amazing and very costly disaster if there are problems after takeoff. they will be Too stressful 30 days, because that’s the time it would take for the device to reach orbit, disassemble and thoroughly test it.

In outer space, and in extreme conditions, it will be necessary to carefully open heat shields with the surface of a tennis court. Scientists explained that it would take a week. The mirror itself will unfold in the next three weeks. Interestingly, after unfolding the individual parts of the mirror must Compatible with 10nm precisionThis is one-thousandth the thickness of a human hair. The entire procedure for disassembling the tool consists of up to 344 steps.

We are talking about a powerful and highly developed space telescope, the launch of which was postponed several times for technical reasons, and it was originally supposed to start work a few years ago. The whole project is wasteful, trivial, 10 billion dollarsI started 18 years ago and participated in it 10000 people.

In recent days, engineers They have already gone through a few moments of terrorWhen vibrations occurred while the device was placed in the racket charging case. Fortunately, the examination did not show any damage to the most important component, ie. Made of beryllium and coated with gold Sturdy 6.5m diameter mirror. Consists of 18 hexagons. Each is more than a meter in diameter, and has a total area of ​​25.4 square metres.

The telescope will be there Watch the abyss of the universe From an orbit around the Sun, that is, from the so-called point L2, where gravity and solar gravity balance. This orbit is 1.5 million kilometers from Earth. This place is no accident. It will also be the James Webb Space Telescope See the universe in infrared, it must be in a place where the temperature is close to absolute zero and free from infrared sources.

Scientists boast that the most powerful space telescope in human history will be sensitive enough He will detect the heat of a bee flying across the moon from Earth. JWST is to change beyond recognition of our observations of phenomena that occur throughout the universe. It will be an accurate tool thanks to which we will be able to get pictures of the first stars and galaxies that formed after that the great explosion.

We will also get information about the formation of many mysterious objects, as well as the discovery of a new planet friendly to life. Maybe they will be Traces of strange civilizations. Humanity needs these kinds of tools to find its place in the universe and answer age-old questions: where did we come from and where are we going.
