New Space Race: Why Orbital Sustainability Is A Strategic Imperative

Outer space is undergoing a structural transformation. Once associated primarily with scientific exploration and national prestige, it has become an increasingly congested, commercialised, and strategically contested domain. Satellites and space-based services now support telecommunications, navigation, weather forecasting, disaster management, climate monitoring, scientific research, financial transactions, and national development. Consequently, the long-term sustainability of outer space is no longer merely a technical or environmental concern; it has become a strategic imperative linked to economic resilience, national security, crisis stability, and the continuity of critical societal functions. Space sustainability may be understood as the ability to conduct space activities indefinitely while preserving the orbital environment for present and future generations. The concept encompasses the prevention of orbital debris, the safe and responsible operation of spacecraft, the protection of space-based infrastructure, and equitable access to the benefits of space technology. The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) has developed 21 voluntary Guidelines for the Long-Term Sustainability of Outer Space Activities. These guidelines address national regulatory frameworks, operational safety, international cooperation, capacity-building, and scientific and technical research. Their significance lies in establishing a shared policy framework, although their non-binding character continues to limit the degree of compliance and accountability. Orbital Congestion and Systemic Vulnerabilities The rapid expansion of space activities has intensified the problem of orbital congestion. The proliferation of small satellites, mega-constellations, launch vehicles, and fragmented space hardware has increased the probability of collision and created complex challenges for space traffic coordination. Orbital debris is particularly dangerous because even small objects travelling at high velocity can damage or destroy operational spacecraft. Space sustainability may be understood as the ability to conduct space activities indefinitely while preserving the orbital environment for present and future generations The resulting chain reaction, commonly associated with the Kessler Syndrome, could compromise the long-term usability of strategically important orbital regimes. This vulnerability has implications extending beyond the space sector: the disruption of satellite-enabled communications, navigation, and remote sensing could affect military operations, emergency response, financial systems, and national infrastructure. Emerging Technologies and Strategic Ambiguity Emerging technologies are adding a further layer of complexity. Artificial intelligence, machine learning, autonomous guidance, on-orbit servicing, advanced propulsion, and increasingly networked satellite architectures are reshaping the design and operation of space missions. AI-enabled systems can improve conjunction assessment, anomaly detection, predictive maintenance, and the management of large satellite constellations. At the same time, autonomous decision-making creates questions concerning safety, explainability, human control, and legal responsibility. An autonomous manoeuvre undertaken in response to an incorrectly classified object or ambiguous signal could generate escalation during an already tense crisis. These risks acquire particular significance in the context of strategic competition. Space systems perform essential functions associated with intelligence, surveillance, and reconnaissance; positioning, navigation, and timing; secure communications; missile warning; and command, control, communications, computers, intelligence, surveillance, and reconnaissance. Their dual-use character makes it difficult to distinguish between peaceful and military activities. A satellite manoeuvre intended for inspection, servicing, or collision avoidance may be interpreted as preparation for interference or attack. This ambiguity creates incentives for worst-case planning and may undermine strategic stability, particularly between states that possess limited channels for military communication and crisis management. Governance, Multilateral Cooperation, and Inclusivity The governance of emerging space technologies has therefore not kept pace with technological development. Existing international space law provides important foundational principles, including the peaceful use of outer space, state responsibility, and the avoidance of harmful interference. Nevertheless, it does not fully resolve contemporary questions concerning autonomous systems, commercial mega-constellations, cyber operations, active debris removal, and the responsible use of proximity operations. Recent United Nations deliberations on responsible behaviours seek to reduce threats through norms, rules, and principles governing state conduct. Such initiatives are important because transparency, information-sharing, notification mechanisms, and confidence-building measures can reduce misperception without requiring immediate consensus on all questions of arms control. No single state can address orbital debris, space situational awareness, or technology-related risks in isolation. Effective governance requires multilateral cooperation involving states, international organisations, commercial operators, scientific institutions, and civil society. The United Nations remains a central platform for developing common epistemic foundations, harmonising technical standards, strengthening information exchange, and encouraging responsible behaviour. Cooperation should include shared debris-monitoring data, improved conjunction warnings, interoperable registration practices, common safety procedures, and sustained dialogue between technical and diplomatic communities. Inclusivity is equally important. Developing countries should not remain passive recipients of decisions made by established space powers. Their participation is essential to ensure that sustainability rules do not unintentionally restrict equitable access to orbital resources or reproduce existing technological inequalities. Capacity-building, technology transfer on mutually acceptable terms, scholarships, training, joint missions, and access to space situational awareness data can help emerging spacefaring states develop independent expertise. COPUOS and its Scientific and Technical Subcommittee provide valuable venues for such engagement. Implications for Pakistan and the Future of Space Order For Pakistan, space sustainability has direct developmental and strategic relevance. Strengthening national expertise in satellite communications, remote sensing, disaster management, climate monitoring, space law, and orbital safety would enhance national resilience. More systematic engagement with COPUOS, UNOOSA, and relevant scientific and technical forums could enable Pakistan to contribute to norm-building while developing partnerships for research, training, and technology cooperation. Ultimately, the objective should not be to restrain technological progress but to embed innovation within a framework of responsibility, sustainability, and strategic prudence. A durable space order will require anticipatory governance rather than reactive regulation, human oversight of autonomous systems, improved transparency, and meaningful participation by all states. Dialogue among scientists, engineers, policymakers, researchers, military practitioners, and commercial operators is indispensable. The future of outer space will depend not only on who can reach orbit, but also on whether states can collectively preserve it as a secure, sustainable, and accessible domain.
