A groundbreaking study published Thursday provides the first direct measurement of pollution from a disintegrating rocket in the upper atmosphere, underscoring urgent concerns about the environmental impact of commercial spaceflight. Researchers traced a plume of debris from a SpaceX Falcon rocket that crashed through the upper atmosphere on February 19th, 2025, after losing control during re-entry. The rocket, launched earlier that month carrying 20 to 22 Starlink satellites, left a concentrated trail detectable across northern Europe, allowing scientists to model the path of its lithium emissions.

This event marks the first time debris from a specific spacecraft breakup has been precisely identified and measured in the near-space region, approximately 80 to 110 kilometers above Earth. Changes in this region can significantly affect the stratosphere, where ozone and climate processes operate.
