The reentry of defunct satellites is anticipated to increase the amount of harmful chemicals in the atmosphere by nearly 650% over natural levels.
Thousands of satellites are currently parked in low Earth orbit, with some that will eventually become defunct and fall back towards our planet’s atmosphere. As they reenter the atmosphere, satellites leave behind a trail of chemicals that eat away at the ozone layer. A new study warns against the growing number of internet satellites, which have contributed to a shocking eight-fold increase of harmful oxides in Earth’s atmosphere over a span of six years. Not all satellites are created equal.
The oxides don’t react chemically with the molecules of the ozone layer; instead they set off destructive reactions between ozone and chlorine that end up depleting the protective layer in Earth’s atmosphere. “Only in recent years have people started to think this might become a problem,” Joseph Wang, a researcher in astronautics at the University of Southern California and lead author of the new study, said in a statement.

Spillover of tropospheric ozone is affecting measurements of stratospheric ozone recovery more than previously realizedIn the final decades of the 20th century, stratospheric ozone depletion—often called, not quite accurately, the ozone hole—was a widespread concern. Halocarbons, including chlorofluorocarbons used as coolants in refrigerators and aerosol spray cans, were linked, beginning in the mid-1970s, to a severely thinning ozone layer.
