Study shows how rocket launches pollute the atmosphere
New research published Thursday bolsters growing concerns that a handful of companies and countries are using the global atmospheric commons as a dumping ground for potentially toxic and climate-altering industrial waste byproducts from loosely regulated commercial space flights.
The new study analyzed a plume of pollution trailing part of a Falcon rocket that crashed through the upper atmosphere on Feb. 19, 2025, after SpaceX lost control of its reentry. The rocket was launched earlier that month, carrying 20 to 22 Starlink satellites into orbit.
The authors said it is the first time debris from a specific spacecraft disintegration has been traced and measured in the near-space region about 80 to 110 kilometers above Earth. Changes there can affect the stratosphere, where ozone and climate processes operate. Until recent years, human activities had little impact in that region.
