UPSC Mains Daily Answer Writing Practice (October 17, 2026): Model Answer & Framework

Daily UPSC Mains Answer Writing: Question & Model Answer Framework (October 17, 2026)

Today's Mains Question (GS Paper 3 - Science & Technology / Internal Security - 15 Marks / 250 Words)

"The rapid militarisation of low-earth and geostationary orbits through 'on-orbit space control weapons' poses a grave threat to global strategic stability. In light of this, analyze the inadequacy of existing legal frameworks and discuss the imperative for robust multilateral governance in outer space."

1. Decoding the Directive & Demand of the Question

Directive: Analyze — This requires breaking down the core issue into its component parts, examining the underlying causes and geopolitical implications of space weaponisation, evaluating current international laws, and putting forward structured solutions.

Core Demands of the Question:

Dimension 1: The technical and strategic nature of modern space threats, specifically "on-orbit space control weapons" (Rendezvous and Proximity Operations - RPO, co-orbital kinetic interceptors, directed-energy weapons).
Dimension 2: A critical appraisal of the lacunae and obsolescence in current international space law (e.g., Outer Space Treaty, 1967).
Dimension 3: The strategic and economic imperatives for multilateral governance, safeguarding critical infrastructure, and preventing the Kessler Syndrome.

2. Structural Outline / Skeleton Framework

Introduction (30-40 words): Define outer space as the "fourth pillar of warfare" and contextualize the shift from peaceful scientific exploration to a contested, militarised geopolitical domain, referencing the rise of on-orbit space control capabilities.
Body Section 1: Nature of Emerging Threats (80-90 words): Discuss how on-orbit weapons (inspectors masquerading as satellites, robotic arms, signal jammers, directed-energy weapons) bypass traditional ground-based Anti-Satellite (ASAT) deterrence by operating directly within orbits.
Body Section 2: Inadequacy of Existing Legal Frameworks (80-90 words): Highlight loopholes in the Outer Space Treaty (1967) — prohibition limited only to weapons of mass destruction (WMDs), lack of verification mechanisms, absence of definitions for "space weapons," and geopolitical polarization rendering the UN Committee on the Peaceful Uses of Outer Space (UNCOPUOS) gridlocked.
Way Forward & Recommendation (40-50 words): Propose binding transparency and confidence-building measures (TCBMs), revitalization of the Conference on Disarmament (PAROS framework), and India's advocacy for responsible state behavior in outer space.
Conclusion (20-30 words): End with a visionary note emphasizing outer space as the common heritage of humankind that requires cooperative stewardship rather than weaponised anarchy.

3. Comprehensive Model Answer

Outer space, once viewed as a sanctuary for peaceful scientific exploration and global communication, has rapidly transformed into a contested geopolitical frontier. The recent proliferation of 'on-orbit space control weapons'—including co-orbital interceptors, rendezvous and proximity operation (RPO) spacecraft, signal jammers, and directed-energy platforms—poses an unprecedented challenge to strategic stability, civilian satellite infrastructure, and global economic security.

Anatomy of Modern Space Threats:
Unlike traditional ground-launched Anti-Satellite (ASAT) missiles that create expansive orbital debris clouds, modern on-orbit capabilities operate stealthily within Low Earth Orbit (LEO) and Geostationary Orbit (GEO). Vehicles capable of station-keeping close to adversarial high-value military or commercial assets can covertly disable, blind, or manipulate critical intelligence, reconnaissance, and communication (C4ISR) architectures. This shifts the paradigm from deterrence through mutual vulnerability to pre-emptive strategic destabilisation.

Inadequacies of Existing Legal Frameworks:
The international architecture governing outer space is structurally obsolete and ill-equipped to handle contemporary technological realities:

The Outer Space Treaty (OST), 1967: While Article IV prohibits the placement of nuclear weapons or WMDs in orbit, it contains a glaring loophole—it does not explicitly outlaw conventional weapons, cyber-attacks, or kinetic-energy systems stationed in space.
Absence of Verification Mechanisms: Existing treaties lack robust inspection regimes, on-orbit monitoring mandates, or clear thresholds to distinguish dual-use technologies (e.g., active debris removal satellites vs. weaponised co-orbital killers).
Geopolitical Deadlock: Proposals like the Russian-Chinese drafted Treaty on Prevention of the Placement of Weapons in Outer Space (PPWT) face Western opposition due to verification deficits, while Western-led norms face multipolar resistance, rendering bodies like the UN Conference on Disarmament gridlocked under the consensus rule.

The Imperative for Robust Multilateral Governance:
Without enforceable multilateral governance, the commercialised digital economy and critical climate monitoring systems face catastrophic risks. Unchecked militarisation drastically elevates the probability of the Kessler Syndrome—a cascading chain reaction of orbital collisions that could render vital orbital bands unusable for generations. Furthermore, weaponisation escalates crisis instability on Earth, as blind-siding satellite constellations can miscue nuclear early-warning systems.

Way Forward:
To secure the orbital commons, the international community must transition from voluntary, non-binding norms to legally binding Transparency and Confidence-Building Measures (TCBMs). Mandatory notification of close approaches, rules of the road for RPO maneuvers, and strict moratoriums on destructive kinetic testing are vital. India, having demonstrated responsible technological capability via 'Mission Shakti', is uniquely positioned to champion a balanced multilateral framework that reconciles national security imperatives with the preservation of outer space as the global commons of humankind.

Conclusion:
Outer space is inextricably linked to Earth's ecological survival and economic connectivity. Establishing a rule-based order in orbit is not merely an arms control issue; it is a fundamental prerequisite for safeguarding planetary security in the 21st century.
