Kessler Cascade vs Active Debris Removal

Watch an orbital shell of satellites and debris evolve over simulated years. Do nothing and collisions fragment objects into more debris, feeding a runaway Kessler cascade. Send a chaser to remove the single highest-risk debris object on a schedule and watch the cascade break instead.

Space & Astronomy3DModerate60 FPS

Run an orbital shell forward through simulated years under two scenarios: leave it alone and watch collisions fragment objects into more debris until the collision rate runs away, or send a chaser to remove the single riskiest tracked object on a schedule and watch object count and collision rate stay roughly flat instead.

⚙ Under the hood

Run an orbital shell of satellites and debris forward through simulated years. Leave it alone and every collision fragments objects into 4-9 new debris pieces, feeding a Kessler-syndrome cascade where collision rate grows with the square of object count until the shell runs away. Switch to Active Removal and a chaser spacecraft periodically captures and de-orbits the single largest, most dangerous tracked debris object, holding object count and collision rate roughly flat instead.
