Satellite megaconstellations could impact ozone hole recovery
When old satellites fall into Earth's atmosphere and burn up, they leave behind tiny particles of aluminum oxide, which eat away at Earth's protective ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022 and will continue to accumulate as the number of low-Earth-orbit satellites increases. The 1987 Montreal Protocol successfully regulated ozone-damaging C
