Scientists Chase Falling Satellite to Study Atmospheric Pollution from Spacecraft Reentries
In a rare airborne mission, scientists chased ESA's Cluster Salsa satellite as it reentered Earth's atmosphere. The fiery descent revealed emissions of lithium, potassium, and aluminum—chemicals that could impact the ozone layer and climate. With satellite reentries increasing, researchers aim to improve pollution models and plan further tracking...

SpaceX Starship Flight 7 Explosion Raises Concerns Over Air Pollution
The explosion of SpaceX’s Starship Flight 7 in mid-January has raised concerns among scientists about atmospheric pollution. The upper stage, weighing 85 tons without fuel, detonated at 90 miles (146 km) above Earth, potentially releasing 45.5 metric tons of metal oxides and 40 metric tons of nitrogen oxides. Experts warn these pollutants could i...

Space Debris Accumulation in the Stratosphere Threatens Major Environmental Risks
The growing presence of satellite space junk, as more satellites enter Earth's orbit, has raised concerns about environmental impacts. Pollution from burnt-up satellites contributes to changes in atmospheric chemistry, with metals like aluminium potentially harming the ozone layer. Scientists warn that satellite re-entries are contributing to a ris...
