29. SDM 6.0: A Modernized Evolutionary Framework for Assessing Long-Term Orbital Capacity and Mitigation Strategies

The rapid expansion of space activities, driven by the deployment of megaconstellations and the diversification of orbital operations, poses an unprecedented challenge to the finite carrying capacity of the near-Earth environment. To effectively manage this delicate ecosystem and establish globally accepted thresholds, robust and adaptable long-term evolutionary models are essential. This...

46. Advances in Modelling Space Capacity with THEMIS

Daniel Lück (Politecnico di Milano)

The THEMIS approach allows modelling consumed space capacity. In the probability-based approach, environmental impact from all major objects (spacecraft, rocket bodies and derelicts) is aggregated. This gives a single value for the consumed space capacity. It can be evaluated for the current space environment and future predictions. Different scenarios or individual events like fragmentations...

49. The Criticality of Orbital Regions: from Local Effects to the Global Health of the Space Environment

Prof. Massimiliano Vasile (University of Strathclyde)

04/06/2026, 11:45

This paper presents a network-theoretic approach to the analysis of the global health of the space environment. We will first introduce an index measuring the criticality of different orbital regions to the status of the environment.
We will then derive a definition of orbital carrying capacity from the criticality score and relate the region criticality to more common object level risk...

33. ADEPT as an Analysis Framework for Space Environment Sustainability Indices

Gregory Henning (The Aerospace Corporation)

As large constellation launch traffic continues to grow and Low Earth Orbit (LEO) becomes more crowded the ability to quantify the effect that space traffic has on operations sustainability in that environment is becoming more important. A variety of indices have been developed or are currently under development to address this problem, each tailored to a specific analytical purpose and...

42. Fragmentation, Loss-of-control And Other Acute Space-based Hazards Score - FLASH - For Fragmentation Hazard Oriented Ground Based Observations

Zoé Medaric

The expansion of human activity in space has resulted in a substantial increase in the number of objects traveling at high velocities in low Earth orbit. These objects are susceptible to mutual collisions, necessitating continuous and precise monitoring. The resulting cascade of debris from successive collisions, commonly referred to as the
Kessler syndrome, poses a significant long-term...
