PThere are now more than 9000 satellites around public expenditures, weather tracking, facilitating communications, helping navigation and monitoring Earth. By 2040, there can be more than 60,000. A new study showed that the emissions resulting from the ending satellites, as they fall on the ground and burn them, will be important in the coming years, with effects on restoring the ozone and climate hole.
Satellite must be replaced after about five years. Most of the old satellites are eliminated by reducing their height and letting them burn with their fall, which led to the release of pollution in the Earth’s atmosphere such as antenna aluminum. To understand the impact of these increased emissions of expired satellites, the researchers simulated the effects associated with the annual version of 10,000 tons of aluminum oxide by 2040 (the amount estimated to be published from 3000 satellites annually, on the assumption of a fleet consisting of 60,000 satellite).
The results that are published in Geophysical Research MagazineShow that the re -entry material will accumulate at high latitudes and may lead to abnormal cases of 1.5 ° C in the upper to the upper atmosphere, reduce wind speeds and exhaust ozone, which may endanger the ozone hole. Other minerals, including titanium, lehium, iron, and copper, will also be released, and their effect has not yet been formulated.
