Space Governance and Traffic Management

Space Traffic Management (STM)

Think of outer space as a busy international airspace — except there is no Air Traffic Control, no unified radar network, no binding rules for who gives way to whom, and no international police. Over 9,000 active satellites and millions of debris fragments share the same sky. Without STM, catastrophic collisions are just a matter of time.

Space Traffic Management (STM) refers to the coordination, monitoring, and regulation of space activities to prevent collisions between satellites, manage orbital congestion, and ensure the long-term sustainability of outer space operations.

Why STM is Needed

• Rapid Increase in Satellites: Growing numbers of satellites, especially mega-constellations, are increasing orbital traffic and collision risks.
• Rising Space Debris: Accumulating debris from collisions, explosions, and ASAT tests threatens operational spacecraft.
• Orbital Congestion: Limited orbital slots and radio frequencies require coordinated management to avoid conflicts.
• Protection of Critical Infrastructure: STM safeguards essential satellite services that support communication, navigation, weather forecasting, and national security.

Key Functions & Components of STM

Function	What It Does
Tracking	Monitors satellites, debris, and rocket bodies in orbit
Collision prediction	Analyses orbital trajectories to detect potential conjunctions
Collision avoidance	Issues alerts; enables operators to perform avoidance manoeuvres
SSA (Space Situational Awareness)	Comprehensive detection and monitoring using radar, telescopes, satellites
Conjunction assessment	Software predicts close approaches between objects
Data sharing networks	International exchange of orbital data for better tracking accuracy

ITU Role: Orbital slot and radio-frequency spectrum allocation are primarily managed by the International Telecommunication Union (ITU) in coordination with national regulators.

Challenges in STM

• Lack of a Global Regulatory Authority: No international body currently has binding authority to manage global space traffic.
• Inconsistent Data Sharing: Security and commercial concerns restrict the exchange of accurate orbital tracking information.
• Commercial Satellite Constellations: Large private satellite networks are increasing congestion and complicating coordination.
• Legal and Liability Issues: Determining responsibility for in-orbit collisions remains challenging under existing space law frameworks.

Space Situational Awareness (SSA)

Space Situational Awareness (SSA) is the capability to detect, track, monitor, and predict the movement of objects in outer space. It is the foundation of STM and space security.

• Countries with advanced SSA: USA, Russia, China, the European Union, Japan, and India.

Key Components of SSA

• Ground-Based Radar Systems: Use radio waves to track satellites and space debris, especially in Low Earth Orbit (LEO).
• Optical Telescopes: Observe and monitor space objects in Medium Earth Orbit (MEO) and Geostationary Orbit (GEO).
• Space-Based Sensors: Satellites equipped with sensors that detect and track other objects in space.
• Data Processing Systems: Analyse tracking data to predict potential collisions and other orbital events.

Project NETRA — India’s SSA Initiative

Project NETRA is India’s answer to the question: ‘Are we watching what’s happening in our own orbital neighbourhood?’ For a country that has invested hundreds of crores in satellites, the ability to track threats and avoid collisions is not optional — it is strategic survival.

• Full name: NEtwork for Space Object TRAcking and Analysis.
• Developed by: ISRO.
• Aim: Detect, track, and monitor space objects to protect India’s space assets.

Five Objectives of Project NETRA

1. Track space debris and operational satellites.
2. Provide early warning of potential satellite collisions.
3. Monitor objects approaching Indian satellites.
4. Reduce dependence on foreign space tracking networks.
5. Strengthen India’s space security and strategic autonomy.

Legal Provisions and Their Challenges in Space Technology

Space law was written in the 1960s and 70s — when only two nations had space programmes, rockets were not reusable, satellites were government assets, and nobody imagined 6,000 Starlink satellites or tourists flying to the ISS. These treaties are the ‘Constitution of Outer Space’ — visionary for their time, but increasingly ill-equipped for the realities of 21st-century space activity.

Outer Space Treaty (1967)

Key Detail	Information
Adopted	1966 by UNGA; entered into force 1967
Context	Cold War — prevent nuclear weapons in space and territorial claims on celestial bodies
Participation	115+ states including India
Significance	Most widely accepted space-related treaty — the ‘Constitution of Outer Space’

Key Principles

Principle	Meaning
Peaceful use	Space used for peaceful purposes; no military bases/weapons testing on celestial bodies
Non-appropriation	No nation can claim sovereignty over Moon/celestial bodies — ‘province of all mankind’
No WMDs in orbit	Bans nuclear weapons and other WMDs in orbit, on celestial bodies, or in outer space
Freedom of exploration	All countries have equal rights to explore/use outer space without discrimination
State responsibility	Countries responsible for all national space activities — including by private companies
Liability for damage	Launching states internationally liable for damage caused by their space objects

Importance of the Outer Space Treaty

• Prevents Territorial Claims: Ensures that outer space and celestial bodies cannot be claimed by any nation.
• Promotes International Cooperation: Encourages countries to collaborate in the exploration and use of outer space.
• Establishes Legal Responsibility: Holds states accountable for their national space activities and space objects.
• Supports Peaceful Use of Space: Preserves outer space as a global commons for peaceful purposes.

Limitations of the Outer Space Treaty

• No Ban on Conventional Weapons: The treaty prohibits WMDs in space but does not explicitly ban conventional space weapons or ASAT systems.
• Lack of Enforcement Mechanism: Compliance depends on states, with no authority to enforce treaty provisions or impose penalties.
• Limited Regulation of Private Companies: The treaty does not adequately address modern commercial activities such as mega-constellations and space tourism.
• Ambiguity on Space Resource Utilisation: Ownership rights over extracted extraterrestrial resources remain legally unclear.
• Limited Provisions on Space Debris: The treaty lacks binding rules for debris mitigation and removal despite growing orbital pollution.
• Lack of Space Traffic Rules: It does not regulate satellite traffic or orbital congestion, increasing collision risks in space.

Rescue Agreement (1968)

• Formally: Agreement on Rescue of Astronauts, Return of Astronauts, and Return of Space Objects.
• Force: 1968; 98 states including India.
• Core principle: Astronauts are ‘envoys of mankind’ — all states must rescue distressed astronauts.

Key Provisions of the Rescue Agreement

• Rescue of Astronauts: States must promptly search for, assist, and ensure the safety of astronauts in distress.
• Safe Return to Launching State: Rescued astronauts must be safely returned to the launching state without delay.
• Assistance in International Waters: States capable of providing help must cooperate in rescuing astronauts beyond national jurisdiction.
• Return of Space Objects: Recovered space objects must be returned to the launching state upon request, with recovery costs reimbursed.

Importance of the Rescue Agreement

• Promotes Humanitarian Cooperation: Encourages international assistance during space emergencies.
• Protects Astronauts: Ensures rescue and safety of astronauts facing distress situations.
• Builds International Trust: Strengthens cooperation and confidence among spacefaring nations.
• Supports the Outer Space Treaty: Implements and reinforces the humanitarian principles of the Outer Space Treaty.

Limitations of the Rescue Agreement

• Limited Scope: Primarily designed for government astronauts and does not clearly cover private astronauts or space tourists.
• Lack of Enforcement Mechanism: Compliance depends on state cooperation, with no penalties for violations.
• Ambiguity in Astronaut Definition: It is unclear whether commercial spaceflight participants qualify as astronauts under the agreement.
• Burden on Rescuing State: Rescue operations may impose significant costs without clear compensation provisions.
• Outdated for Modern Missions: The agreement does not adequately address commercial spaceflight, multinational missions, or deep-space exploration.

Liability Convention (1972)

This Convention establishes rules for international liability for damage caused by space objects, expanding on the responsibility principles in the Outer Space Treaty. Adopted and entered into force in 1972, it addressed the growing number of satellites launches and potential accidents. Currently, 98 states, including India, are parties.

Key Provisions

This is one of the most frequently tested distinctions in the entire chapter — pay close attention:

Where Damage Occurs	Type of Liability	What It Means
On Earth or to aircraft in flight	Absolute liability	Launching state is fully liable; the affected state does NOT need to prove fault or negligence
In outer space (e.g., satellite collision)	Fault-based liability	Liability depends on fault; the injured state MUST prove negligence or responsibility

• Launching state responsibility: Defined broadly — a state qualifies as a ‘launching state’ if it (1) launches a space object, (2) procures the launch, or (3) provides the launch site or facility. In joint missions, multiple states can share liability.
• Claims procedure: Compensation claims must go through diplomatic channels from the affected state to the launching state; if unresolved, a Claims Commission may be established.

Importance

• Provides a legal framework for compensation in space accidents
• Encourages responsible space operations
• Protects states from damage caused by foreign space objects
• Promotes accountability in space activities

Limitations

• Difficulty in proving fault in space: Determining which satellite or operator caused a collision is technically complex, undermining the fault-based regime.
• State-centric framework: Holds states, not private companies, liable — creating legal complications as commercial space activity grows.
• Complex and slow claims process: Diplomatic-channel claims can be lengthy and politically sensitive.
• Few precedent cases: Rarely invoked, leaving its interpretation uncertain for future disputes.

Registration Convention (1976)

This Convention requires countries to register objects launched into outer space — developed as a direct follow-up to the Outer Space Treaty. Adopted in 1974, it entered into force in 1976. As of June 2026, 78 states, including India, are parties.

Key Provisions

• Mandatory registration: Launching states must maintain a national registry, typically including the object’s name, date and location of launch, orbital parameters, and general function.
• UN register of space objects: States must submit registration details to the United Nations Office for Outer Space Affairs (UNOOSA), which maintains the UN Register of Objects Launched into Outer Space.
• Jurisdiction and control: The launching state retains jurisdiction and control over the registered object and any personnel aboard it, while it is in outer space or on a celestial body.

Quick Fact: UNOOSA (the United Nations Office for Outer Space Affairs) is the UN office responsible for promoting international cooperation in space activities and administering UN space treaties.

Importance

• Enhances transparency in global space activities
• Facilitates identification of jurisdiction and responsibility for space objects
• Supports liability determination when a space object causes damage
• Contributes indirectly to Space Situational Awareness
• Promotes responsible and accountable space governance

Limitations

• Voluntary compliance in practice: Despite being a legal obligation, delays and incomplete reporting frequently occur due to weak enforcement.
• No behavioural regulation: Records objects, but does not regulate satellite conduct, congestion, or debris mitigation.
• Private sector challenges: The rapid growth of commercial launches and mega-constellations has created reporting and oversight gaps.
• No enforcement mechanism: Lacks penalties or monitoring mechanisms to ensure full compliance.

Moon Agreement (1984)

Formally the Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, this treaty expands the legal framework of the Outer Space Treaty specifically to the Moon.

Adopted in 1979, it entered into force in 1984. Its objective is to regulate human activities on the Moon and other celestial bodies, ensuring their exploration and use benefit all humanity.

A Critical Fact for Mains The Moon Agreement currently has only 18 state parties — and crucially, major spacefaring nations, including the US, Russia, China, and India, are NOT parties to it. This single fact explains almost all of its practical weaknesses.

Key Provisions

• Common heritage of mankind: The Moon and its natural resources are declared the ‘common heritage of mankind’ — no country can claim ownership of lunar territory or resources.
• Peaceful use of the Moon: The Moon must be used exclusively for peaceful purposes; military installations and weapons testing are prohibited.
• Regulation of resource exploitation: Proposes creating an international regime to govern lunar resource use once feasible, ensuring equitable benefit-sharing and fair access.
• Environmental protection: States must avoid harmful contamination of the Moon and prevent adverse changes to Earth’s environment from extraterrestrial material.
• International cooperation: Encourages sharing of scientific knowledge, cooperation in lunar research, and assistance to astronauts in distress.

Importance

• Extends international space law beyond Earth orbit
• Introduces the concept of equitable sharing of space resources
• Promotes sustainable and peaceful lunar exploration

Limitations

• Limited ratification: Major space powers have not joined, sharply reducing its practical influence on contemporary lunar exploration.
• Commercial restrictions: Its ‘common heritage’ and resource-sharing provisions are seen by many as a potential obstacle to private space mining.
• Lack of enforcement mechanisms: Relies on voluntary compliance, with no binding enforcement provisions.

Artemis Accords (2020)

The Artemis Accords are a set of non-binding international principles guiding cooperation in the civil exploration and use of the Moon, Mars, asteroids, and other celestial bodies.

They support the goals of the Artemis Programme, which aims to return humans to the Moon, establish a sustained human presence, and enable future deep-space missions.

Established in 2020 by the USA, the Accords currently (as of June 2026) have 68 state parties  including India.

Key Principles

• Peaceful exploration: All activities must be conducted exclusively for peaceful purposes, in line with international space law.
• Transparency in activities: Signatories commit to openly sharing policies, mission plans, and scientific objectives.
• Interoperability: Space systems should be designed to function together across national programmes.
• Emergency assistance: Astronauts are regarded as envoys of humanity; nations must assist astronauts from any country in distress.
• Registration of space objects: Participants must comply with obligations to register spacecraft and missions.
• Release of scientific data: Discoveries and data should be shared with the global scientific community.
• Preservation of space heritage: Historic human sites on the Moon, such as the Apollo 11 landing site, should be protected as cultural and scientific heritage.
• Space resource utilisation: Recognises that extraction and utilisation of space resources can be conducted under international law, without implying national sovereignty — this remains one of the most debated aspects of the Accords.

Criticisms

• USA-centric: Some countries view the Accords as reflecting USA-led governance of space activities.
• Resource extraction concerns: Critics argue they may implicitly legitimise unilateral extraction of space resources.
• Limited global participation: Major space powers such as China and Russia are not signatories, and pursue alternative cooperation frameworks instead.
