South Atlantic anomaly

South Atlantic anomaly



Souce


A report published by the National Office of the Oceanic and Atmospheric Administration, the NOA of the United States, warns that in recent years this anomaly has grown by 5%.


And it should already be called an anomaly of South America because it fully affects countries like Argentina, Chile, Brazil, Uruguay, Paraguay, there are no scientific studies that affirm that it can affect the forms of life that exist in the region, nor to living beings, nor to plants, nor to any other animal.


It is an anomaly that affects space satellites, spacecraft, and which may perhaps be the symptom of a change in the earth's magnetic poles, but a symptom that we do not know if it indicates that it is going to happen soon or that it will to occur thousands of years from now.


The anomaly is a region where the protective magnetic field of the earth is eroded, it is not that there is a hole, it is not a correct term, but for some unknown reason in that area the Van Allen belts, which are belts where particles are concentrated radiation is located a shorter distance from the earth's surface, about 200 kilometers below normal, which also causes solar radiation to be higher than in other areas of the planet.



In the video above, which is from the European Space Agency, it shows the area of radiation impacts captured by Swarm instruments or satellites of the European Space Agency from April 2014 to August 2019, the area of the anomaly is appreciated. suffers more radiation impacts, we are talking about space satellites, not the surface.


Space satellites and space stations orbiting the earth, such as the international space station and the Chinese station although they are in space, they are still within the protective umbrella of the earth's magnetic field, the international space station is between 330 to about 420 kilometers above the earth, while the lower Val Allen belt begins at an altitude of 500 kilometers, but of course in that area the belt is lower and going through that area, that region of the South Atlantic anomaly has its risks .


The international space station has had to install extra special shielding to deal with this problem. Another problem, for example, is that of the Hubble Space Telescope, which is orbiting the Earth and when it has to pass through that area, it does not make any observations, except some very special and rare.


Some satellites and ships have also suffered failures when passing through the area, it is believed that the anomaly started a series of events that ended with the destruction of Hitomi, which was the most powerful x-ray observatory in Japan, and other satellites have suffered disastrous failures. when passing through this area where the earth's magnetic field is more eroded.


One of the things with which there is speculation is that this anomaly is a symptom of a future magnetic or geomagnetic reversal or polarity, resulting in a change in the magnetic poles, from the North to the South and from the South to the N`, while these types of changes occur, the protective magnetic field of the earth would be in a chaotic state and would suffer a sudden decrease.
