Kessler syndrome: vertical diffusion rate?

- The post asks how a Kessler syndrome cascade, likely starting in crowded LEO with varied inclinations, spreads debris. - Simulations show rapid secondary-collision debris dispersal; higher-inclination impacts might intersect more populated near-equatorial traffic. - The author questions how quickly fragments diffuse to higher orbits versus being left on elliptical paths cleared by atmospheric drag. - They ask whether daughter collisions can confer sustained vertical delta‑V to create stable, near‑circular higher orbits or if other mechanisms exist.

Kessler syndrome: vertical diffusion rate?

- Suggests a Kessler cascade would likely begin in LEO, which contains many vehicles at varied inclinations. - Notes simulations show rapid secondary-debris spread, and posits higher-inclination fragments may intersect more and spread faster. - Asks how quickly fragments are transported to higher orbits versus being cleared at lower altitudes
