Star link killing the ozone layer.
First generation (Gen1) Starlink satellites are being retired to make way for newer models. "More than 500 of the 4700 Gen1 Starlinks have now reentered,"
When Starlinks reenter, they disintegrate before hitting the ground, adding metallic vapors to the atmosphere.
In February 2023, NASA flew a WB-57 aircraft 60,000 feet over Alaska to collect aerosols. 10% of the particles contained aluminum and other metals from the "burn-up" of satellites.
What we're observing is a giant uncontrolled experiment in atmospheric chemistry. The demise of just one Gen1 Starlink satellite produces about 30 kilograms (66 pounds) of aluminum oxide, a compound that eats away at the ozone layer. A new study finds these oxides have increased 8-fold between 2016 and 2022, and the recent surge is increasing the pollution even more.
