Orbital Debris Management Simulator

Earth is surrounded by hundreds of thousands of tracked fragments of dead satellites, spent rocket stages and collision shrapnel, each one moving on its own Kepler orbit at several kilometres per second. This simulator visualizes that field in miniature: fragments of different altitude and inclination sweep around a central Earth, occasionally crossing paths closely enough to collide — and each collision creates new fragments, the seed of a runaway Kessler-syndrome cascade. A net-collector satellite continuously hunts down and removes debris to show how active debris removal (ADR) missions fight back against the growing hazard. Adjust debris count, simulation speed, collisions and the cleanup mission to see how each changes the field's stability.
