Context: The U.S.A military’s move towards offensive and defensive space-control capabilities has raised concerns. On September 14, U.S.A Air Force Secretary Troy Meink, confirmed by Space Force Chief Gen. Douglas Schiess, acknowledged the deployment of “on-orbit space control weapons” to defend against hostile actions. This development highlights the growing militarisation of outer space and the need for greater international regulation.

Need of Multilateral Governance in Space

1. Growing militarisation of space: Major powers are developing counter-space capabilities, making Earth’s orbit a potential future battlefield.
2. Dual-use nature of satellites: The same satellite systems may serve both civilian and military purposes, making it difficult to distinguish peaceful activities from military operations.
3. Risk of miscalculation: When two steerable or autonomous satellites approach each other without understanding the other’s intentions, ambiguity can result in unintended escalation.
4. Unclear definition of hostile action: Existing international rules do not clearly define what constitutes a “hostile action” in outer space.
5. Gaps in the Outer Space Treaty: The treaty prohibits nuclear weapons and weapons of mass destruction in orbit, but does not comprehensively prohibit conventional weapons or all forms of destructive counter-space activities.
6. Ambiguous military doctrines: When a country describes a space capability as defensive while its military doctrine permits both offensive and defensive space operations, it can create uncertainty about its actual intentions.
7. Inadequate existing legal framework: Existing rules, including the Liability Convention, were developed when space technology was less complex and are not always adequate for today’s highly interconnected and dual-use space systems.
8. Commercialisation of space: Commercial satellites increasingly perform functions critical to national security and civilian life, making attacks on such systems capable of causing widespread disruption.
9. Emergence of autonomous systems: Future satellites may operate with considerable autonomy and even run artificial intelligence models onboard, creating additional challenges for attribution and accountability.
10. Difficulty in determining accountability: Existing rules are too broad to clearly determine responsibility when autonomous or commercially operated space assets cause damage.

Major Challenges

1. Lack of precise international definitions of hostile acts and acceptable military activities in space.
2. Weak regulation of conventional space weapons compared with the restrictions on nuclear weapons and weapons of mass destruction.
3. Rapid technological change is outpacing existing international law.
4. Increasing involvement of private companies makes attribution and state responsibility more complicated.
5. Strategic mistrust among major powers can encourage counter-space capability development.
6. Absence of clear rules for autonomous and AI-enabled satellites creates uncertainty regarding human control and accountability.
7. Risk to civilian infrastructure: Since satellite-based networks underpin contemporary societies, attacks on space assets can have consequences far beyond the military domain.

Way Forward

1. Strengthen multilateral space governance through negotiations involving major space powers and other stakeholders.
2. Clarify what constitutes hostile action and establish internationally accepted thresholds for military action and escalation.
3. Develop rules for responsible behaviour in space, particularly regarding proximity operations, autonomous satellites and potentially harmful interference.
4. Strengthen transparency and confidence-building measures through notification, information-sharing and communication mechanisms between space powers.
5. Address conventional weapons: International discussions should move beyond the existing focus on nuclear weapons and WMDs to address conventional counter-space capabilities.
6. Establish accountability for autonomous systems: Rules should clearly determine responsibility for actions of autonomous and AI-enabled space assets.
7. Regulate commercial and dual-use satellites: Private space companies operating strategically important assets should be incorporated into the international governance framework.
8. Use existing UN mechanisms: The UN Open-Ended Working Group on Prevention of an Arms Race in Outer Space (PAROS) provides an avenue for governments to address emerging security concerns.
9. Promote multilateral space arrangements: Countries should work towards agreements that establish clear thresholds of action and escalation and reduce the possibility of miscalculation.

Conclusion: Outer space is no longer a purely scientific or civilian domain. Its growing military, commercial and dual-use character requires rules that keep pace with technological change. A rules-based, transparent and multilateral governance framework is essential to prevent miscalculation, protect civilian space infrastructure and ensure that outer space remains peaceful and secure.

Question: The increasing militarisation and commercialisation of outer space has created new challenges for international peace and security. Discuss the need for multilateral governance of space activities.
