A new analysis published as a preprint on arXiv argues that orbital debris in Earth orbit should be understood as a coupled operations-stability problem rather than a simple inventory of objects. The work develops a reduced-order control framework using publicly available data from ESA, NASA, FCC, NOAA, JAXA and OECD sources through 2026. This is a preprint and has not undergone peer review.

Current statistics show roughly 44,870 tracked objects and more than 15,800 tonnes of orbiting mass. Models estimate populations of about 54,000 objects larger than 10 cm, 1.2 million objects between 1-10 cm, and 140 million in the 0.1-1 cm size range. The study notes that 96 percent of the current LEO risk index comes from inactive objects.

Operationally, the growing workload is evident in constellation management. Public SpaceX data indicate Starlink collision-avoidance maneuvers increased from 6,873 in the December 2021-May 2022 period to 144,404 in December 2024-May 2025. The preprint identifies two distinct altitude regimes: a traffic peak near 500-600 km that drives conjunction alerts and a persistence-driven risk peak near 850 km dominated by long-lived inactive high-mass objects.

The authors highlight NASA studies showing benefit-cost ratios of 20-750 for shortening post-mission disposal timelines from 25 to 15 years and greater than 100 for reducing uncertainty in high-risk conjunction predictions.

The framework suggests orbital-debris services will develop as three linked markets: compliance-focused mitigation for new launches, end-of-life servicing with premium space situational awareness, and publicly supported remediation of the existing legacy hazard stock. The analysis relies on modeling assumptions about collision kernels, breakup severity and orbital lifetimes; it aggregates existing public datasets rather than collecting new observations and therefore carries the limitations inherent in such models.
