Satellites' aluminium oxide harming ozone layer, threatens recovery efforts

Satellites burning up in the atmosphere are releasing aluminium oxide particles, damaging the ozone layer. Research shows an eight-fold increase in these oxides from 2016 to 2022 due to the rise in low-Earth-orbit satellites. With planned constellations, 912 metric tons of aluminium could fall to Earth annually, increasing aluminium oxide levels by 646%. This poses a threat to ozone recovery efforts.
