In 1975, chemists Mario Molina and Sherwood Rowland They found that the compounds are widely used on Earth, Fluorocarbon (CFC)They contributed to the formation of dangerous a hole in the ozone layerAt first, at first they were not perceived too seriously, over time it was clear that what they said was true and that the situation could become critical if nothing was done to turn back. This led to signing Montreal protocolWith which the progressive ban of CFC was resolved. Since then, the hole of the ozone layer was slightly closed. However Space launch Soon they began to slow down. At first it was anecdotal, but the promotion of the space race greatly exacerbates things.
This is the conclusion of the investigation conducted by the doctor Sandro VattioniFrom Zurich. After the analysis of several studies conducted in recent years, he proved that spatial issues release substances that weaken the ozone layer in a similar way, as CFC did. Even more serious, as they are produced in the field of a much more delicate atmosphere.
If we take into account that the ozone layer protects all living organisms from The most harmful radiation of the sunThe growth of the ozone layer is a huge risk. Measures should be taken as soon as possible if we do not want to return to the starting point or, even worse, continue Moving to the catastrophe.
It was not enough to ban HFU
HFU is gases, consisting mainly of Chlorine, fluorine and carbonWhose use has become popular Since the 1920s. Initially, they were conceived as substances refrigerants, Although later its potential was discovered as Aerosols and solvents.
Molina and Rowland discovered that in the atmosphere sunny ultraviolet radiation produces Chlorine department CFC molecules. These chlorine atoms react with ozone molecules, which leads to a series of chemical reactions that cause The destruction of the mentioned ozone.
After confirming that all this was true and that, indeed, I preferred the formation of a hole in the ozone layer, CFC was chosen. Today they are revealed in almost all. Aerosol deodorantic boats are no longer controlled by CFC, just as they are not found in the cooling of air conditioning.
As a result, the hole of the ozone layer was slightly closed. At some points, it closed faster, in others the process slowed down. Now we see it This happens more slowly. Even at a certain time of the year, the hole in the ozone layer becomes larger. And this is no longer the fault of CFC, but the release of space.
What are the space launches related to?
More than 30 years ago it was found that space issues contribute to increase the hole of the ozone layerHowever, at that time, the consequences were minimal. The problem is that there are more and more spatial issues and, as a result, its consequences are more serious.
For example, in 2019 there were 97 Orbital Space Lelease All over the world. In 2024, after only 5 years, this figure promoted up to 258. The mass launch of satellites of companies such as Starlink, as well as many other scientific, civil or commercial flights, gradually leads to an increase in geometric progress.
Therefore, new calculations on the influence of the ozone layer should be made. And this is that the biggest problem of pollution by space releases is in the place where they are produced. If pollutants are released on the surface of the earth, clouds and rain can wash off their part. On the other hand, when these compounds are produced In the middle or high atmosphere, There is no washing that eliminates them. Therefore, harmful effects can be 100 times higher.
It is known that the main pollutants that are released with spatial outputs are Gas chlorine and soot particles. The first destroys ozone in the same way as CFC molecules. In the case of soot, this helps to increase temperature, which, in turn Accelerate reactions that contribute to the depletion of ozone in the atmosphere.
The only missiles that do not generate these pollutants are those that use Cryogenic fuel. However, it is more difficult for them to manipulate, so only 6 % space They eat in this way.
How will all this affect the future?
Taking into account the current data, scientists from the University of Kenterbury and Zurich developed Simulation On the influence of the cosmic race on the hole of the ozone layer. With the current rhythm in 2030 there will be some 2040 Space Leleas. If the share of each type of fuel is preserved, the average thickness of the ozone in the world will decrease by almost 0.3%With a seasonal decline to 4% in Antarctica. All this will go to befall with the restoration of the hole in the ozone layer, which was achieved with the ban on KhFU. And the worst thing is that these scientists took into account only space launches, but they believe that the insults to missiles that have already completed their mission can reduce the figures even worse.
Measures must be taken by exploding new methods of promoting missiles and, above all, to determine whether all spaces are really necessary are really necessary. There may be those who think that they are economically, but remember that the hole in the ozone layer is harmful to all of us. There are things that can even stop money.
