    The fall of space debris on Earth: what are the chances that it will kill a person

    Scientists have made calculations that show how much the fall of artificially created objects can threaten the inhabitants of the Earth.

    Canadian scientists from the University of British Columbia, led by Michael Byers, conducted a study in which they calculated the likelihood that humanity could suffer from a missile fall in the next decade. It turned out that it is quite difficult to die from the fall of space debris, but measures must be taken to control the entry of such objects into the atmosphere, according to ScienceAlert.

    So far, no deaths from space debris have been recorded. There is only evidence that such incidents led to injuries and the destruction of infrastructure.

    As for the fall of various space objects to Earth, it is worth remembering that every minute microscopic particles of asteroids and comets fall on our planet. Unbeknownst to us, they form a layer of dust on Earth weighing 40,000 tons annually. According to the calculations of scientists, only once every 100 years a sufficiently large meteorite with a diameter of tens of meters can fall to Earth. But this is still natural space debris.

    “In our study, we paid special attention to the uncontrolled descents of spent space rocket stages, which can pose a threat to humanity,” says Byers.

    Using computer simulations, scientists have calculated the places on Earth where over the next 10 years rockets and other space debris can fall. According to their estimates, there is a three times greater risk of falling missiles in the southern latitudes than in the northern ones.

    “Our data shows that uncontrolled rocket drops can occur over densely populated cities in Indonesia, Bangladesh and Nigeria,” says Byers.

    But scientists warn that their data is based on statistics on the amount of space debris over the past 30 years. But the amount of this garbage is growing with the increase in the number of rocket launches and more and more satellites.

    , but also descent into the atmosphere. You can generally make sure that the rocket has no fuel left, and it would completely burn out in the upper atmosphere, “says Byers.

    As for satellites, many of them after end-of-life remain in orbit and may collide with other satellites, which also leads to an increase in space debris. Therefore, scientists believe that all such objects should be lowered into the upper atmosphere, where they will completely burn out.

    By the way, strong geomagnetic storms pose a serious threat to Starlink satellites, as Focus< /em>.
