The Kessler Syndrome describes a feedback loop: as debris density increases, collisions become more frequent, each collision adds more debris, which causes more collisions. Beyond a critical threshold, the cascade becomes self-sustaining — even without new launches.

The process isn't sudden — it's a slow-burning runaway that can take decades to become irreversible.
These three events alone account for roughly a third of all tracked debris. The Cosmos-Iridium collision was the first accidental hypervelocity collision between two catalogued objects — proving the Kessler model was not just theory.
Kessler risk is not uniform — it concentrates in altitude bands where debris lingers longest.
Current models give a sobering but not hopeless picture — if action is taken.
