Story summary

A study by Technische Universität Braunschweig warns that rising space activity, especially megasatellite constellations, injects materials from reentering spacecraft into Earth's atmosphere, potentially weakening the ozone layer.
The influx of space waste more than doubled from 3 to 7 tons per year between 2020 and 2024.
Lithium, titanium, and aluminum from spacecraft contribute to atmospheric pollution.
Researchers call for further study to determine long-term effects on atmospheric chemistry and climate.
