Abstract:

This work analyzes the November 2021 Russian antisatellite (ASAT) test against the COSMOS 1408 spacecraft and assesses its implications for satellite operators and the near-Earth space environment. Using optical observations, Space-Track data, NOTAM interpretation, and calibrated breakup modeling, the study reconstructs the intercept conditions and the resulting debris cloud evolution. Three-dimensional volumetric risk assessment techniques are applied to estimate debris spatial density, fragment lifetimes, and time-dependent collision risk to active spacecraft. Results show a substantial, sustained increase in conjunction rates and collision warnings in Low Earth Orbit, particularly for sun-synchronous Earth-observing constellations and the International Space Station. The analysis identifies recurring “conjunction squalls” driven by coplanar and counter-rotating orbital geometries, which dramatically increase operator workload and safety-of-flight burden. Fragment lifetime estimates indicate that while roughly half of tracked debris reenters within the first year, thousands of lethal non-trackable fragments persist for years, maintaining elevated risk. The study concludes that ASAT-generated debris events impose long-lasting operational and safety impacts, underscoring the need for predictive risk assessment, improved space situational awareness, and international efforts to deter debris-generating activities.
