A spectacular SpaceX rocket fireball over Europe has now been linked to measurable lithium pollution 100km above Earth.

Scientists warn this could be an early warning sign as satellite mega-constellations expand.
Is upper atmospheric pollution the next environmental challenge?
When a SpaceX Falcon 9 rocket broke apart during re-entry over Europe on February 19, 2025, it created a spectacular fireball visible from Ireland to Germany.
But beyond the dramatic light show, scientists have now confirmed something more concerning: the rocket’s uncontrolled descent released a significant plume of lithium into the upper atmosphere — marking the first time pollution from a specific rocket re-entry has been directly measured at such altitude.
