The massive constellation of SpaceX satellites is sure to be a spectacle in the sky for lovers of space and telescopes. But the increasing number of satellites in the earth's orbit has become the center of numerous controversies in recent years that cause concern and stimulate various researches.

In addition to concerns about increasing the problem of cosmic debris and jeopardizing the work of astronomers, a recent scientific study pointed to another potential challenge with possible catastrophic consequences. According to that research, decommissioned satellites often burn up in Earth's atmosphere, leaving behind "magnetized dust." This dust, according to experts from the University of Iceland, can cause an increase in atmospheric pollution and even threaten the Earth's magnetic protection against dangerous cosmic radiation.

Student Sierra Solter-Hunt said she was "shocked that this topic is not being investigated more intensively, given the alarming nature of the situation." Solter-Hunt estimates that the amount of metal particles in the Earth's atmosphere has increased significantly since the beginning of the era of space exploration, and the rate of this increase is accelerating due to the increasing number of satellites in orbit.

Dust from "dead" satellites is retained in the ionosphere, where it could remain almost indefinitely. There are concerns that this accumulation of dust could create a new electrically charged grid around the planet, which could have long-term consequences for Earth's magnetosphere.

Although some experts doubt that even a large number of satellites burning up in the atmosphere could seriously threaten the Earth's magnetic mantle, such as John Tarduno from the University of Rochester who claims that the assumptions from the mentioned research are "oversimplified and probably incorrect", however there are others which highlight the importance of this research.

They claim that it indicates a lack of knowledge about the impact of space debris on Earth, especially among ordinary people, but it is also stated that it has a negative effect on the atmosphere and that it is important to investigate all potential consequences.

SpaceX has so far launched almost 6 thousand, and Amazon plans to send a little over 3 thousand into space. That's a far cry from the million satellites Salter-Hunt mentions in the scientific paper. Although the consequences are unlikely to be absolutely catastrophic in the near future, this topic must not be ignored.

The phenomenon of cosmic debris has not yet been fully explored, and as space activity increases, it is important to continuously monitor its impact on Earth and take appropriate measures to protect the planet.
