The increasing activity in low-Earth orbit (LEO) has led to discussions about the sustainability of space operations.

Orbital Classification System

The number of operational satellites has risen significantly, and there is a need for a structured approach to managing this crowded environment. Industry experts propose an orbital classification system similar to aviation standards to enhance safety and increase the carrying capacity of defined orbital volumes. This model would impose maneuvering capabilities on large constellations while allowing smaller operators to function with fewer restrictions, balancing the needs of stakeholders in the space economy.

Economic Implications

The economic implications of space operations are also considered, as the launch of multiple large constellations from different nations increases the potential for collisions and debris generation. Experts emphasize the need to scrutinize the risks associated with large constellations more rigorously than smaller satellites. The absence of a centralized international authority for space traffic management complicates efforts to establish global rules. However, experts suggest that launch states could play a role in enforcing an orbital classification system, as outlined in the 1967 Outer Space Treaty. The concept of an orbital classification system can be integrated within existing treaty frameworks, allowing for gradual development as the industry grows.

Addressing Space Debris

The increasing complexity of LEO necessitates clear guidelines to mitigate risks and promote responsible space operations. Various organizations are taking proactive measures to address the issue of space debris. Initiatives such as active debris removal projects and non-binding agreements seek to create a sustainable space environment. Behavioral economics is also being explored as a means to promote space sustainability. Incentives and public recognition can encourage better practices among space operators, while naming and shaming can create pressure to adhere to best practices. The goal is to ensure that space remains a viable domain for future generations by establishing norms and standards for responsible behavior.
