Issues in the Earth’s Orbit: Space Debris, Congestion and Risks

Table of Contents

Context: The rapid expansion of satellite launches and mega-constellations (e.g., Starlink) has made Earth’s orbital environment increasingly crowded, raising concerns about space debris, collision risks, and weak global governance mechanisms.

Issues in the Earth’s Orbit

Orbital Congestion: Rapid growth of satellites and mega-constellations is increasing orbital crowding (over 10,000 active satellites; thousands launched annually).
Space Debris: Fragments from defunct satellites and collisions threaten active spacecraft (>36,000 debris objects >10 cm tracked by ESA/NASA).
Collision Cascades: Even small debris travelling at ~28,000 km/h can destroy satellites, generating thousands of new fragments (Kessler Syndrome risk).
Tracking Limitations: Small debris and fragments often cannot be consistently tracked, increasing uncertainty in collision avoidance.
Uneven Data Access: Orbital tracking data and space situational awareness information are unevenly shared across countries and operators.
Uncertain Responsibility: Difficulty in identifying which satellite caused debris or damage, complicating liability and accountability

Issues in Global Governance

Poor Monitoring: Regulators often rely on operators’ pre-launch promises rather than verified compliance after deployment.
Outdated Treaties: Existing frameworks like the Outer Space Treaty (1967) were designed for state-led space activity, not today’s commercial space economy.
Weak Debris Regulations: Debris mitigation guidelines (e.g., UN COPUOS guidelines) remain voluntary with limited enforcement.
Private Sector Expansion: Growing role of private companies launching mega-constellations without globally harmonised regulatory oversight.
Regulatory Fragmentation: Different countries impose varying licensing requirements, leading companies to operate under more permissive jurisdictions.
Lack of Duty-of-Care Standards: No global agreement defining acceptable orbital congestion or long-term stewardship obligations.

Opportunity for India

Norm-Setting Role: India can shape global norms on space sustainability and orbital responsibility while drafting its national space legislation.
Responsible Space Governance: Embedding debris mitigation, collision avoidance, and end-of-life satellite disposal into national licensing systems.
Leadership in Space Sustainability: Promoting international standards for space situational awareness and debris monitoring.
Technology Development: Investing in debris tracking systems, space traffic management, and active debris removal technologies.
Diplomatic Influence: Leveraging platforms like UN COPUOS, G20, and Quad space initiatives to promote rules-based space governance.
