The rapid growth of satellite mega‑constellations means thousands of spacecraft are de‑orbited each decade, releasing heavy‑metal and black‑carbon particles into the stratosphere. Harvard physicist John Dykema warns that these emissions can alter sunlight absorption, disrupt stratospheric circulation, and accelerate ozone depletion. While the exact climate impact remains uncertain, the added thermal energy and chemical contaminants could shift storm tracks and delay ozone recovery. Policymakers are urged to consider material and propellant choices to mitigate these emerging atmospheric risks.
