The importance of determining an equilibrium state for space traffic management

The rapid expansion of human and robotic activity in low Earth orbit makes critically important the need to implement effective space traffic management (STM). This will be one of the most crucial engineering and policy challenges of the 21^st century. The emergence of massive communications constellations, orbiting data centers, inhabited space stations and increasing quantities of space debris has intensified orbital congestion and collision risks throughout low Earth orbit (LEO). As a result, determining an “equilibrium state” for STM has become essential for ensuring the long-term sustainability, safety and economic viability of space operations. In this context, equilibrium refers to a dynamically stable orbital environment in which spacecraft launches, operational lifetimes, debris generation and disposal rates remain balanced so that collision probabilities and long-term orbital degradation are minimized.
