The Satellite Graveyard: Modeling the Kessler Cascade
A cascade of colliding space debris could one day render low Earth orbit unusable, cutting off satellite launches for generations. This episode follows the logic of the Kessler Syndrome — the tipping point after which orbit becomes a shell of shrapnel we cannot escape.
Listen in the Fylom app.
Orbital debris travels at speeds reaching thirty-three thousand miles per hour, turning small fragments into lethal projectiles.
Atmospheric drag naturally clears debris below six hundred kilometers but fails to protect higher orbital shells.
Stochastic models predict a full orbital collapse within one hundred to two hundred forty-three years.
A single satellite collision can generate ten thousand shards, creating a self-sustaining feedback loop of destruction.
Stabilizing the orbit requires removing sixty large objects, like spent rocket stages, every single year.
Geopolitical friction persists because debris removal tools are often viewed as dual-use space weapons.

Fylom generates episodes like this on any topic you're curious about.
Fylom episodes are researched, written, and voiced by AI. Automated checks help catch inaccuracies, but episodes aren't reviewed by a human and AI can still get things wrong. Treat them as a starting point, not a source of record — more in our accuracy disclaimer.
