Abstract

The exponential increase in artificial satellites, growing from 852 in 2004 to over 9,000 in 2023, has intensified the risk of the Kessler Syndrome: a cascading chain reaction of orbital collisions. This paper analyzes the dynamics of space debris accumulation to identify the primary orbital features contributing to this systemic risk. We compiled and analyzed Two-Line Element (TLE) datasets from Space-Track.org and historical collision data using a Python-based data mining approach. Specifically, we derived satellite velocities using the Vis-Viva equation and evaluated the correlation of five key features, launch piece count, orbital period, apogee, perigee, and Radar Cross Section (RCS) size, with debris density. Our evaluation reveals that apogee and orbital period exhibit the strongest correlation with the risk of the Kessler Syndrome, indicating that satellites in higher orbits pose a disproportionately greater threat to long-term sustainability due to navigational constraints. Contrary to common assumptions, our data suggests that velocity and object size (RCS) show negligible direct correlation with collision incidence in the current dataset. Based on these findings, we propose mitigation strategies focusing on integrating AI-driven autonomous navigation systems and deploying advanced radiation-resistant shielding materials to enhance the resilience of high-orbit assets.
