A new study published in Geophysical Research Letters warns that internet satellite networks like Elon Musk’s Starlink could contribute to ozone layer depletion.
Scientists at the University of Southern California’s Department of Astronautical Engineering said the increase in low-earth orbit satellites, currently over 8,000 with around 6,000 from Starlink, raises concerns.
These satellites, made with significant amounts of aluminum and designed to last about five years, produce aluminum oxide when they re-enter Earth’s atmosphere and burn up.
This compound triggers harmful chemical reactions, severely damaging the ozone layer.
The study noted an eightfold increase in aluminum oxides from 2016 to 2022, with potential for greater surges as satellite launches continue.
