Quantify the current and projected scale of orbital debris, assess the probability and timeline of catastrophic cascade events, and evaluate the adequacy of existing governance frameworks for managing Earth's orbital environment.

ESA Space Debris Office tracking data combined with NASA Orbital Debris Program Office collision risk models. Kessler Syndrome probability modeling from peer-reviewed studies in Acta Astronautica. Policy analysis of existing frameworks: UN COPUOS guidelines, ITU frequency coordination, and national debris mitigation requirements.

There are currently 36,000 tracked objects larger than 10cm in orbit, an estimated 1 million objects between 1-10cm (untrackable but lethal to spacecraft), and 130 million fragments smaller than 1cm. The Starlink constellation alone added 5,000+ objects since 2019. LEO collision risk has increased 50% since 2015.

The probability of a Kessler cascade — a chain reaction of collisions rendering LEO unusable for decades — has risen from theoretical to actuarially significant: modeling studies suggest a 10-20% probability of a significant cascade event within 30 years at current growth rates. 6 trillion in global economic activity depends on continued LEO access.
