Daily UPSC Mains Answer Writing: Question & Model Answer Framework (October 20, 2026)

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

"The weaponization of outer space through on-orbit space control technologies poses unprecedented threats to global strategic stability and orbital sustainability. In this context, examine the imperatives for a renewed multilateral space governance architecture and India's strategic technological roadmap."

1. Decoding the Directive & Demand of the Question

Directive: Examine — This requires a critical investigation into the anatomy of the issue, weighing the technological and geopolitical drivers of on-orbit weaponization, analyzing the systemic failures of existing governance mechanisms, and outlining constructive pathways forward for national and international security.

Demand of the Question: The answer must be structured across three core dimensions:

  • Dimension 1: The evolving threat matrix of on-orbit space control weapons (co-orbital anti-satellite systems, directed-energy weapons, and Rendezvous and Proximity Operations - RPO).
  • Dimension 2: The governance deficit in international law (loopholes in the 1967 Outer Space Treaty and stalemates in PAROS).
  • Dimension 3: India’s strategic, technological, and diplomatic imperatives to safeguard its space assets while championing responsible multilateralism.

2. Structural Outline / Skeleton Framework

  • Introduction (30-40 words): Define outer space as a "Global Commons" and a critical infrastructure domain, transitioning from a peaceful scientific frontier to an active contested geopolitical battleground (citing recent escalations in on-orbit space control capabilities).
  • Body Section 1: The Anatomy of On-Orbit Threats (70-80 words): Discuss co-orbital anti-satellite (ASAT) weapons, RPO capabilities, cyber-attacks on ground-space links, and the looming risk of cascading space debris (Kessler Syndrome).
  • Body Section 2: Multilateral Governance Deficit (60-70 words): Highlight the inadequacy of the Outer Space Treaty (1967), the lack of legally binding verification mechanisms, and geopolitical deadlocks at the UN Conference on Disarmament (PAROS).
  • Body Section 3: India’s Strategic Imperatives & Technological Roadmap (70-80 words): Address India's vulnerabilities as a space-faring power (navigational, communication, and reconnaissance assets), operationalizing defensive doctrines (Mission Shakti, Defence Space Agency, IndSpaceEx), and balancing BRICS/multilateral forums with strategic technological self-reliance.
  • Way Forward & Recommendation (40-50 words): Propose legally binding Transparency and Confidence-Building Measures (TCBMs), international codes of conduct for responsible military behaviors in orbit, and domestic R&D in resilient architectures.
  • Conclusion (20-30 words): Summarize with a forward-looking thought on preserving space for future generations in alignment with the ethos of Vasudhaiva Kutumbakam and sustainable technological governance.

3. Comprehensive Model Answer

Outer space, historically viewed as an expanse for peaceful scientific exploration, has rapidly transformed into a contested multi-domain operational theater. The deployment of on-orbit space control weapons—ranging from co-orbital interceptors and robotic arms capable of grappling satellites to directed-energy systems—poses a grave challenge to strategic stability, economic security, and orbital sustainability.

The Evolving Threat Matrix in Orbital Regimes

Modern military doctrines increasingly treat space as a warfighting domain. Unlike traditional ground-based kinetic ASAT tests (such as India’s Mission Shakti in 2019), contemporary powers are pivoting toward Rendezvous and Proximity Operations (RPO). Satellites capable of loitering near critical national security assets, monitoring movements, or physically disabling them blur the line between civilian utility and military aggression. Furthermore, weaponizing orbits drastically elevates the risk of the Kessler Syndrome—a cascading chain reaction of space debris rendering vital orbital regimes like Low Earth Orbit (LEO) unusable.

The Multilateral Governance Deficit

Global space governance remains structurally antiquated. The foundational Outer Space Treaty (1967) prohibits only the placement of weapons of mass destruction (WMDs) in orbit, remaining conspicuously silent on conventional weapons, electronic jamming, and dual-use space control technologies. Efforts at the UN Conference on Disarmament toward Prevention of an Arms Race in Outer Space (PAROS) are plagued by geopolitical polarization, leaving the domain without enforceable verification mechanisms or binding norms of responsible state behavior.

India’s Strategic and Technological Roadmap

As a preeminent space-faring nation heavily reliant on orbital assets for remote sensing, disaster management, navigation (NavIC), and secure communications, India faces acute strategic exposure. Navigating this high-stakes environment requires a three-pronged national roadmap:

  • Enhancing Defensive & Resilient Architecture: Accelerating domestic capabilities through integrated bodies like the Defence Space Agency (DSA) and war-gaming exercises such as IndSpaceEx to deter hostile orbital interference.
  • Technological Hardening: Investing in on-orbit maneuverability, encrypted inter-satellite links, and redundant small-satellite constellations to ensure survivability against kinetic and electronic disruption.
  • Proactive Multilateral Diplomacy: Leveraging forums like the UN Committee on the Peaceful Uses of Outer Space (UNCOPUOS) and BRICS to advocate for verifiable Transparency and Confidence-Building Measures (TCBMs) and international norms against destructive debris-generating activities.

Conclusion

The militarization of orbits threatens the global commons upon which modern digital economies depend. Sustainable space governance cannot rely purely on deterrence; it demands a collective global commitment to rules-based order, ensuring that outer space remains an arena for human advancement rather than an extension of terrestrial geopolitical conflict.
