The proliferation of satellite launches, particularly those associated with megaconstellation projects like Starlink, poses a significant threat to the ozone layer due to the chemical reactions and emissions generated during deployment into Low Earth Orbit (LEO). Aluminum deterioration from megaconstellation satellites can chemically react with ozone, forming aluminum oxide, which has the potential to deplete the protective ozone layer. Additionally, rocket launches that are essential for deploying satellites into LEO contribute to ozone damage through emissions of various gases and particles.

Moreover, the drifting particulates from satellites into the stratosphere can also react with ozone molecules, leading to potential ozone losses. With approximately 5,000 active and defunct satellites already present in LEO and plans for launching over 40,000 Starlink satellites in the near future, concerns are escalating about the cumulative impact on the ozone layer. The sheer volume of satellites, especially from megaconstellations, could inadvertently trigger uncontrolled geoengineering experiments with unforeseen environmental consequences, further exacerbating the ozone depletion issue.

Common Myths About Satellites and Ozone

Common misconceptions surrounding the interaction between satellites and the ozone layer often lead to unfounded concerns and misinterpretations of their actual impact on atmospheric dynamics. Here are some common myths debunked:
