Over the last four years, I have noticed a quiet but steady shift in UPSC question papers. Space is no longer just a Science and Technology topic about ISRO’s latest launch. The Commission is now testing your understanding of the legal and diplomatic architecture that governs outer space. If you have been ignoring space law, this is your signal to pay attention.
In this piece, I will walk you through the entire framework of international space law, explain India’s position, and show you exactly how this topic connects to both GS-II (International Relations) and GS-III (Science and Technology). By the end, you should be able to handle any UPSC question on this subject with confidence.
Where This Topic Sits in the UPSC Syllabus
Space law is one of those cross-cutting topics that sits at the intersection of multiple papers. This is precisely why UPSC finds it attractive. It tests whether you can connect science with diplomacy, and policy with ethics.
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies | Science and Technology — developments and their applications in everyday life |
| Mains | GS-II | International Relations — important international institutions, agencies, and fora |
| Mains | GS-III | Science and Technology — awareness in the fields of Space; indigenisation of technology |
| Mains | GS-IV | Ethics — corporate governance, probity (in context of space commercialisation) |
Related topics in the same syllabus space include India’s nuclear doctrine, the Antarctic Treaty System, Law of the Sea (UNCLOS), and technology transfer regimes like MTCR and Wassenaar Arrangement. If you are preparing space law, revise these parallels too. UPSC loves to draw comparisons between global commons governance frameworks.
The Foundation: Five UN Space Treaties You Must Know
All of modern space law rests on five treaties negotiated under the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS). India is an active member of COPUOS, which makes these treaties directly relevant to our foreign policy.
The Outer Space Treaty of 1967 is the cornerstone. Think of it as the constitution of space. It establishes three big principles. First, outer space is free for exploration by all states. Second, no nation can claim sovereignty over any celestial body. Third, weapons of mass destruction cannot be placed in orbit or on the Moon. India signed and ratified this treaty. Over 110 countries are parties to it.
The Rescue Agreement of 1968 requires states to assist astronauts in distress and return them to their launching state. It treats astronauts as “envoys of mankind” — a phrase UPSC has picked up in at least one previous question.
The Liability Convention of 1972 is critical for understanding space debris disputes. It says a launching state is absolutely liable for damage caused by its space object on the surface of the Earth. For damage in outer space, liability is fault-based. This distinction between absolute and fault-based liability is a classic Prelims fact.
The Registration Convention of 1976 requires states to register every object they launch into space with the UN Secretary-General. This creates a public record and helps attribute responsibility.
The Moon Agreement of 1979 is the most controversial. It declares the Moon and its resources the “common heritage of mankind” and calls for an international regime to govern resource exploitation. India has not signed this treaty. Neither have the US, Russia, or China. This is a significant fact — the treaty is largely considered a failure because major space-faring nations rejected it.
Why This Topic Is Gaining UPSC Relevance Now
Three developments have pushed space law from the margins to the mainstream of UPSC preparation.
First, India’s space sector is being opened to private players. The Indian Space Policy 2023 and the creation of IN-SPACe (Indian National Space Promotion and Authorisation Centre) mean that private companies can now build and launch satellites. This raises questions about liability, regulation, and intellectual property — all of which fall under space law. India is also working on a Space Activities Bill to create a domestic legal framework. UPSC has already asked about IN-SPACe in 2024.
Second, the Artemis Accords led by the United States are creating a parallel governance framework outside the UN treaty system. India signed the Artemis Accords in 2023 during Prime Minister Modi’s state visit to the US. This is a major IR development. The Accords promote interoperability, transparency, and the extraction of space resources — which puts them in tension with the Moon Agreement’s “common heritage” principle. This tension is exactly the kind of analytical question UPSC Mains loves.
Third, space debris and anti-satellite weapons are becoming urgent global concerns. India’s Mission Shakti in 2019 demonstrated our ASAT (Anti-Satellite) capability. While it proved India’s technological strength, it also generated debris and raised questions about responsible behaviour in space. The US declared a moratorium on destructive ASAT tests in 2022 and pushed for a UN resolution. India’s position on this is nuanced and worth studying.
India’s Position in Global Space Governance
India has consistently supported the peaceful use of outer space. Our space programme, founded by Vikram Sarabhai, was designed from the start for developmental purposes — communication, weather forecasting, resource mapping, and disaster management.
At the UN, India advocates for preventing an arms race in outer space (PAROS). India supports the idea of a legally binding treaty on this, though Western nations prefer non-binding norms. This is a GS-II point about India’s multilateral diplomacy.
India is also a member of the Inter-Agency Space Debris Coordination Committee (IADC) and follows its debris mitigation guidelines. ISRO has been passivating (removing stored energy from) its spent rocket stages to reduce debris risk. These operational details show India’s commitment to responsible space behaviour — useful for answer writing.
How UPSC Tests This Topic
From my experience analysing papers, UPSC approaches space law in three ways. In Prelims, expect factual questions — which treaty deals with liability, what does the Outer Space Treaty prohibit, or which agreement India has not signed. In Mains GS-II, expect questions linking space governance to India’s foreign policy, the Artemis Accords, or UN reform. In Mains GS-III, expect questions on India’s space policy, commercialisation, and the regulatory framework.
A likely Mains question pattern for 2026 could be: “The existing international space law framework is inadequate to address the challenges of space commercialisation and militarisation. Discuss with reference to India’s position.” To answer this well, you need to know the treaties, their gaps, India’s diplomatic stance, and recent developments like the Artemis Accords and the Space Activities Bill.
Key Points to Remember for UPSC
- The Outer Space Treaty 1967 prohibits sovereignty claims and WMDs in space but does not ban conventional weapons — this gap is frequently tested.
- India has ratified four of the five UN space treaties. The exception is the Moon Agreement 1979.
- The Liability Convention uses absolute liability for surface damage and fault-based liability for damage in orbit — know this distinction cold.
- India signed the Artemis Accords in 2023, aligning with the US-led framework for lunar exploration and resource utilisation.
- IN-SPACe is the regulatory body for authorising private space activities in India, created under the Department of Space.
- India supports a legally binding treaty to prevent an arms race in outer space (PAROS) at the Conference on Disarmament.
- The concept of space as a “global commons” connects this topic to UNCLOS, the Antarctic Treaty, and climate governance — prepare them together.
Space law is no longer an optional or exotic topic for UPSC. It sits right at the crossroads of India’s technology ambitions and its multilateral diplomacy. I would suggest making a single consolidated note covering all five treaties, India’s space policy, and the Artemis Accords. Read the MEA’s press releases on space cooperation — they give you the exact language to use in Mains answers. Steady, focused preparation on this topic can earn you marks across multiple papers.
