science 🛰️ Falling satellites threaten ozone layer with metal dust
Decaying satellites in low Earth orbit are posing a potential risk to Earth's ozone layer. This issue involves the massive number of satellites currently operating or planned for launch. As of February 2026, there are about 14,000 active satellites, with over a million more in planning. The aluminum from burning satellites creates alumina particles, which could affect atmospheric phenomena like polar winds. Scientists are currently lacking data on the exact ozone impact, leaving the future uncertain. 🛰️
