Orbital Object Surge in 2025: Overview and Significance
In 2025, over 4,600 objects were placed into Earth's orbit following 315 space launches, marking an unprecedented increase in orbital congestion (The Hindu, 2025). This surge is primarily driven by commercial satellite deployments, notably SpaceX's Starlink constellation which alone accounts for over 4,000 satellites in low Earth orbit (LEO) by mid-2025 (SpaceX data). Concurrently, the global population of trackable space debris has exceeded 34,000 objects (ESA Space Debris Office Report, 2025), intensifying collision risks and complicating space traffic management (STM).
India contributed 9 orbital launches in 2025, including missions using PSLV and GSLV launch vehicles (ISRO Annual Report, 2025). The rapid increase in orbital objects highlights the urgent need for robust regulatory frameworks and international cooperation to mitigate debris and manage traffic effectively.

International Legal Framework Governing Outer Space Activities
The Outer Space Treaty, 1967 forms the foundational legal framework regulating state activities in outer space, emphasizing peaceful use and prohibiting national appropriation (UN Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space). The Liability Convention, 1972 establishes state liability for damages caused by space objects, critical for addressing collision incidents.
India is a signatory to these treaties and operates under the Indian Space Research Organisation Act, 1969 (Section 3), which establishes ISRO and defines its functions. However, India’s domestic regulatory regime is evolving, with the Space Activities Bill drafted but pending enactment, aiming to regulate private space actors and ensure compliance with international obligations.
- Outer Space Treaty, 1967: Sets principles for peaceful use, non-appropriation, and international responsibility.
- Liability Convention, 1972: Defines liability for damage caused by space objects.
- ISRO Act, 1969: Establishes ISRO’s mandate for space research and development.
- Space Activities Bill (draft): Seeks to regulate private space activities and promote safety and sustainability.
- ITU Radio Regulations: Governs satellite frequency allocation to prevent signal interference.
Economic Dimensions of the Space Launch Surge
The global space economy was valued at approximately USD 469 billion in 2023, with a projected compound annual growth rate (CAGR) of 6.7% through 2028 (Bryce Space and Technology Report, 2024). Commercial satellite launches now constitute over 60% of total launches globally, generating multi-billion-dollar revenues from satellite services including telecommunications, Earth observation, and navigation.
India allocated around INR 13,949 crore (~USD 1.7 billion) to its space budget for 2023-24 (Union Budget 2023-24), reflecting increased investment in space infrastructure and capabilities. However, the rise in orbital objects has increased insurance premiums for satellite operators by an estimated 15-20%, driven by elevated collision risks (Lloyd’s of London Space Risk Report, 2024).
- Global space economy size: USD 469 billion (2023), CAGR 6.7% through 2028.
- India’s space budget: INR 13,949 crore (~USD 1.7 billion) for 2023-24.
- Commercial launches: >60% of total launches globally.
- Insurance premiums: Increased by 15-20% due to debris collision risks.
- Space traffic management market: Projected USD 3.5 billion by 2027 (MarketsandMarkets, 2024).
Key Institutions in Space Launches and Traffic Management
ISRO remains India's primary space agency responsible for satellite launches and space research. The Indian National Space Promotion and Authorization Centre (IN-SPACe) was established to regulate and promote private sector participation in space activities, overseeing licensing and compliance.
Internationally, the United Nations Office for Outer Space Affairs (UNOOSA) facilitates cooperation and treaty implementation. NASA and the European Space Agency (ESA) lead in debris monitoring and mitigation, with ESA reporting over 34,000 trackable debris objects in orbit. Private companies like SpaceX dominate commercial satellite launches, with Starlink accounting for a significant portion of new satellites.
- ISRO: Indian government agency for space research and launches.
- IN-SPACe: Regulator for private space activities in India.
- UNOOSA: UN body for space cooperation and treaty oversight.
- NASA & ESA: Leaders in debris monitoring and space traffic management.
- SpaceX: Private US company with largest commercial satellite constellation.
Space Debris and Traffic Management Challenges
The surge in orbital objects has escalated collision risks, prompting a 25% increase in collision avoidance maneuvers in 2024 compared to 2023 (NASA Orbital Debris Program Office). Space debris threatens operational satellites, manned missions, and long-term space sustainability.
Current space traffic management (STM) is fragmented, with no single global authority. National frameworks vary in scope and enforcement. India lacks a comprehensive, legally binding STM and debris mitigation policy, creating regulatory uncertainty for private players and limiting enforcement compared to the US and Europe.
- Global debris population: >34,000 trackable objects (ESA, 2025).
- Collision avoidance maneuvers: +25% in 2024 vs 2023 (NASA).
- STM market projected to reach USD 3.5 billion by 2027.
- India’s regulatory gap: No binding STM/debris mitigation law yet.
- Private sector uncertainty due to pending Space Activities Bill.
Comparative Analysis: India vs China Space Launch and Regulatory Framework
| Aspect | India | China |
|---|---|---|
| Number of launches in 2025 | 9 orbital launches (ISRO Report, 2025) | 55 launches focusing on lunar exploration and space station assembly |
| Regulatory Framework | Draft Space Activities Bill pending; no comprehensive STM policy | Strict national debris mitigation guidelines aligned with UN COPUOS |
| Private Sector Role | Regulated by IN-SPACe; regulatory uncertainty persists | State-controlled with emerging private partnerships under strict oversight |
| International Cooperation | Signatory to Outer Space Treaty and Liability Convention; limited active global leadership | Active participant in UN COPUOS; implements international debris mitigation standards |
Way Forward: Policy and Institutional Imperatives
- Enact the Space Activities Bill to provide a clear legal framework for private space actors and debris mitigation in India.
- Develop a national Space Traffic Management (STM) policy aligned with international best practices to regulate orbital congestion and collision avoidance.
- Enhance India’s participation in global forums like UN COPUOS and promote multilateral agreements on debris mitigation and STM.
- Invest in indigenous debris tracking and removal technologies to safeguard Indian assets in space.
- Strengthen public-private partnerships under IN-SPACe to ensure compliance with safety and sustainability norms.
