    [15th January 2026] The Hindu OpED: An exploration of India’s mineral diplomacy

    PYQ Relevance

    [UPSC 2024] “The West is fostering India as an alternative to reduce dependence on China’s supply chain and as a strategic ally to counter China’s political and economic dominance.” Explain with examples.

    Linkage: It is relevant to GS II (International Relations) and GS III (Economic Security). The statement links to India’s role in Western strategies for supply-chain diversification, critical minerals security, and balancing China’s economic and strategic dominance.

    Mentor’s Comment

    India’s clean energy transition is increasingly constrained not by ambition, but by access to critical minerals and rare earths. This article examines how India’s minerals diplomacy has expanded rapidly across continents, yet remains limited by weak domestic processing capacity and fragmented strategic focus. The analysis is crucial for GS Paper III (Energy, Resources, Industrial Policy) and GS Paper II (International Relations).

    Why in the News

    India’s clean energy transition is facing serious risks due to shortages of critical minerals and rare earths, worsened by tighter global export controls. For the first time, India has adopted a multi-continent minerals diplomacy strategy, signing nearly a dozen agreements in the last five years with Australia, Japan, Africa, Latin America, and Canada. This is a clear shift from India’s earlier ad-hoc and import-based mineral sourcing. However, the article points out a major weakness: India has not been able to convert these partnerships into strong value-chain security because of poor domestic refining, processing, and midstream capacity. This structural gap affects key sectors such as electric vehicles, batteries, semiconductors, and renewable energy equipment.

    What makes minerals central to India’s clean energy transition?

    1. Clean energy dependence: Requires lithium, cobalt, nickel, copper, and rare earths for EVs, batteries, wind turbines, and solar technologies.
    2. Supply concentration: Global production and processing dominated by a few countries, increasing vulnerability.
    3. Export controls: Tightening restrictions by China and others heighten urgency for diversification.
    4. Strategic risk: Disruptions affect industrial growth, energy security, and technological sovereignty.

    How has India expanded its mineral diplomacy?

    1. Bilateral partnerships: Nearly a dozen agreements signed in five years across multiple continents.
    2. Policy integration: External engagement aligned with domestic mineral policy reforms.
    3. Market building: Focus on responsible sourcing and standards-based mineral markets.
    4. Strategic shift: Move from trade-based imports to long-term access arrangements.

    Why are Australia and Japan pivotal partners?

    1. Australia-reliability: Offers political stability, reserves, and a long-term strategic vision.
      1. Investment coordination: India-Australia Critical Minerals Partnership identified five lithium and cobalt projects (2022).
    2. Japan-resilience model:
      1. Diversification strategy: Responded to China’s rare-earth export restrictions with stockpiling, recycling, and R&D.
      2. Institutional strength: Demonstrates importance of long-term planning and industrial policy.

    What role does Africa play in India’s mineral strategy?

    1. Resource availability: Lithium (Namibia), rare earths and uranium (Namibia), copper and cobalt (Zambia).
    2. Existing trade links: Provide entry points for deeper cooperation.
    3. Structural risks:
      1. Regulatory volatility: Shifting trade rules and restrictions on raw exports.
      2. Geopolitical competition: China’s entrenched presence raises coordination costs.
    4. Strategic requirement: Needs long-term engagement, not transactional deals.

    How do geopolitics shape India’s options with the US, EU, Russia, and West Asia?

    1. United States:
      1. Volatility risk: Trade policy shifts reduce reliability.
      2. Technology leverage: Strategic Technology TRUST Initiative enables joint processing, batteries, and clean tech.
    2. European Union:
      1. Regulatory alignment: Battery Regulation and Critical Raw Materials Act support recycling and transparency.
      2. Sustainability convergence: ESG norms create compliance-driven partnerships.
    3. Russia:
      1. Resource abundance: Nickel, cobalt, and lithium.
      2. Operational limits: Sanctions, financing barriers, and logistics constrain reliability.
    4. West Asia:
      1. Institutional deficit: Lacks depth in mining frameworks despite proximity.

    Why is Latin America an emerging frontier?

    1. Resource centrality: Argentina, Chile, Peru, and Brazil crucial for copper, nickel, and lithium.
    2. Indian investments:
      1. KABIL signed a USD 200 million lithium exploration and development agreement with Argentina.
      2. Hindalco expanding overseas copper assets.
    3. Competitive pressure: China and Western firms are already deeply embedded.
    4. Strategic lesson: Late entry requires value-added partnerships, not extraction-only deals.

    Why are integrated partnerships more important than access alone?

    1. Processing gap: India lacks refining and midstream capacity.
    2. Value-chain weakness: Extraction without processing perpetuates dependency.
    3. Technology deficit: Advanced batteries and recycling dominate future competitiveness.
    4. Strategic failure risk: Country-to-country agreements cannot substitute domestic capability.

    Conclusion

    India’s mineral diplomacy has expanded rapidly and strategically, but access without processing capacity cannot deliver resilience. Long-term security depends on domestic refining, recycling, technology acquisition, and institutional coordination. The next phase must shift from signing agreements to building value chains.

  • Corruption Challenges – Lokpal, POCA, etc

    Graft law: Shielding honest officers vs unmasking the corrupt

    Why in the News?

    A Constitution Bench of the Supreme Court of India has delivered a split verdict on the constitutional validity of Section 17A of the Prevention of Corruption Act, 1988, which requires prior government approval before investigating public servants for decisions taken in official capacity. The ruling highlights a clear judicial divide between protecting honest administrative decision-making and preventing misuse of legal safeguards to shield corruption. The split verdict raises serious concerns about investigative independence, executive control, and the effectiveness of India’s anti-corruption framework.

    What is the case about?

    1. Provision involved: Section 17A of the Prevention of Corruption Act requires prior government approval to investigate public servants.
    2. Reason for challenge: The provision places executive approval before investigation.
    3. Judicial outcome: A Constitution Bench delivered a split verdict.
    4. Core issue: Balance between protecting honest decisions and enabling corruption probes.
    5. Constitutional concern: Impact on investigative independence and separation of powers.
    6. Practical effect: Influences how corruption cases against public servants begin.

    What does Section 17A of the Prevention of Corruption Act provide?

    • The Prevention of Corruption Act, 1988 seeks to deter abuse of public office while ensuring administrative efficiency and Section 17A was inserted in 2018
    • Statutory safeguard: Requires prior approval of the competent authority before police can investigate a public servant for offences linked to official decisions.
    • Temporal scope: Applies to decisions taken during discharge of official functions.
    • Objective stated: Prevents harassment of honest officers for bona fide policy or administrative decisions.
    • Operational impact: Delays or blocks initiation of criminal investigation at the threshold stage.

    Why was Section 17A challenged before the Supreme Court?

    1. Investigative barrier: Converts executive approval into a precondition for inquiry, not merely prosecution.
    2. Equality concern: Creates differential treatment between public servants and private individuals accused of corruption.
    3. Accountability deficit: Enables governments to shield senior officials involved in high-level decision-making.
    4. Federal implications: Central approval requirement affects investigations by State agencies.

    What did the majority opinion hold? (Viswanathan-Pardiwala)

    1. Decision-making protection: Ensures fearless and independent administration without retrospective criminalisation of policy decisions.
    2. Screening mechanism: Introduces a preliminary filter to separate mala fide allegations from genuine corruption.
    3. Proportionality: Balances anti-corruption goals with administrative efficiency.
    4. Continuity with precedent: Aligns with earlier judicial concerns about over-criminalisation of bureaucratic discretion.
    5. Outcome: Section 17A upheld as constitutionally valid.

    Why did Justice Nagarathna dissent?

    1. Object and purpose violation: Section 17A undermines the core intent of the PCA to detect and deter corruption.
    2. Executive dominance: Grants the executive a veto over criminal investigation, eroding separation of powers.
    3. Accountability erosion: Shields high-ranking officials whose decisions have the largest corruption impact.
    4. Investigative distortion: Transforms an independent inquiry into a permission-based process.
    5. Outcome: Section 17A held unconstitutional for frustrating anti-corruption enforcement.

    How does this judgment contrast with earlier anti-corruption jurisprudence?

    1. Pre-2018 framework: No approval required for investigation; sanction applied only at prosecution stage.
    2. Judicial trajectory: Earlier rulings prioritised investigative autonomy to uncover systemic corruption.
    3. Post-amendment shift: Emphasis moves toward protecting decision-makers over exposing wrongdoing.
    4. Institutional impact: Marks a doctrinal shift from deterrence-centric to discretion-protective interpretation.

    What are the implications of the split verdict?

    1. Legal uncertainty: Conflicting constitutional interpretations weaken clarity on enforcement.
    2. Future reference: Likely referral to a larger Bench for authoritative resolution.
    3. Policy dilemma: Forces reconsideration of how India balances governance efficiency with probity.
    4. Institutional trust: Public confidence hinges on whether safeguards become shields for corruption.

    Conclusion:
    The debate on Section 17A reflects a deeper governance dilemma between protecting honest public servants and ensuring effective anti-corruption enforcement. A democratic state requires safeguards that encourage fearless decision-making while preserving independent investigation and public accountability. Only a balanced institutional design can strengthen both administrative integrity and democratic trust.

    PYQ Relevance

    [UPSC 2020] “Institutional quality is a crucial driver of economic performance”. In this context suggest reforms in the Civil Service for strengthening democracy.

    Linkage: Institutional quality depends on accountable and transparent public servants, which improves economic performance. Recent debates on safeguards for public servants highlight the need to balance decisional autonomy with strict accountability.

    China reiterates claim over Shaksgam Valley

    Why in the news?

    China has reasserted its cartographical claim over the Shaksgam Valley and defended its infrastructure activities there as legitimate. India has strongly rejected these claims, reiterating that Shaksgam Valley is Indian territory and that the 1963 China Pakistan agreement ceding the area is illegal and invalid.

    About Shaksgam Valley (Trans Karakoram Tract)

    • Location: High altitude valley north of the Karakoram range, bordering China’s Xinjiang region
    • Political status: Part of Pakistan occupied Kashmir, specifically the Hunza Gilgit region

    Havana Syndrome Back 

    Why in the News?

    A renewed debate has emerged in the United States over Havana Syndrome after reports that the United States Department of Defense has been testing a covertly acquired device capable of emitting pulsed radio frequency energy, according to a report by CNN.  

    What is Havana Syndrome

    • Also officially termed Anomalous Health Incidents (AHIs)
    • First reported in 2016 by US diplomats stationed in Havana, Cuba
    • Symptoms include:
      • Severe headaches
      • Dizziness and vertigo
      • Cognitive difficulties and memory issues
      • Sensations similar to head trauma without visible injury
    • Since then, cases have been reported across Europe, Asia, Latin America and Africa
    • Affected personnel include:
      • Diplomats
      • Intelligence officers
      • Military personnel

    Why It Is Difficult to Diagnose

    • No single, universally accepted medical definition
    • Delayed clinical examinations in many cases
    • Symptoms overlap with stress related and neurological disorders
    • Lack of direct physical evidence in most incidents

    Cause: 

    Havana Syndrome, officially termed Anomalous Health Incidents (AHIs), does not have one conclusively proven cause.

    • Pulsed electromagnetic / microwave energy: Most plausible explanation. Can cause neurological symptoms without visible injury.
    • Possible directed-energy device exposure: Suspected use of portable energy-emitting devices for covert harassment or surveillance.
    • Psychological and stress-related factors: High-stress diplomatic environments may have contributed in some cases.
    • Acoustic (sound-based) causes: Initially suspected but largely ruled out due to weak scientific support.
    • Environmental or chemical exposure: Considered but no common toxin identified across locations.

  • Foreign Policy Watch: India-Iran

    [14th January 2026] The Hindu OpED: Decisive new factors in the Iran conundrum

    PYQ Relevance

    [UPSC 2018] In what ways would the ongoing US-Iran Nuclear Pact Controversy affect the national interest of India? How should India respond to its situation?

    Linkage: This question directly examines how great-power sanctions, nuclear diplomacy, and West Asian instability affect India’s energy security, strategic autonomy, and regional interests. It links India’s foreign policy choices with sanctions diplomacy, balance of power politics, and national interest formulation in a volatile geopolitical environment.

    Mentor’s Comment

    Iran has seen many phases of unrest in the past, and the government usually managed them in a predictable way. However, recent developments show deep structural changes in Iran’s society, economy, and geopolitics, which are weakening the regime’s old methods of handling crises. This article explains what is different this time, why it is important, and how it affects the region and the world, including India’s strategic interests.

    Why in the News?

    Iran is facing a new wave of protests across the country, driven mainly by economic collapse rather than ideological issues, unlike earlier movements. The unrest began with the Tehran Bazaar strike in December 2025, which was unusual because traders have traditionally supported the regime. In 2025, the Iranian rial lost about 45% of its value, falling to 1.45 million per dollar, making even basic imports like rice, sugar, and edible oil too expensive despite government price controls.

    Although protests have spread nationwide and over 2,000 deaths have been reported, key pillars of the state, the oil sector, ruling elite, Islamic Revolutionary Guard Corps

    (IRGC), and the military, remain loyal, stopping any immediate regime collapse. This crisis is important because it reveals new weaknesses in Iran’s system, while also showing the regime’s ability to survive strong internal unrest and external pressure.

    How did the current Iranian crisis originate?

    1. Currency Collapse: Reflects macroeconomic breakdown, with the rial depreciating nearly 35 times since 1979.
    2. Bazaar Shutdown: Signals rupture in state-merchant symbiosis; bazaaris historically functioned as regime stabilisers.
    3. Import Compression: Renders essential goods unaffordable despite subsidies and controlled prices.
    4. Social Spillover: Mobilises unemployed youth and low-paid workers into a nationwide protest movement.

    Why is the Bazaar strike a decisive structural break?

    1. Elite Defection: Demonstrates withdrawal of support from an influential economic pressure group.
    2. Historical Parallel: Mirrors the 1979 episode when bazaar support withdrawal accelerated Shah’s fall.
    3. Economic Squeeze: Caused by sanctions, IRGC dominance, and Bonyads (powerful, quasi-governmental charitable trusts in Iran) crowding private enterprise.
    4. Policy Uncertainty: Lack of clarity on whether IRGC-linked economic capture will be reversed.

    Why has Iran’s traditional protest-management strategy worked so far?

    1. Four-Stage Playbook: Combines policing, controlled concessions, attrition tactics, and exemplary punishment.
    2. Institutional Loyalty: IRGC and army remain unified, preventing elite fragmentation.
    3. Economic Continuity: Oil sector remains operational, sustaining regime finances.
    4. Leadership Vacuum: Absence of an alternative political leadership among protesters.

    What new vulnerabilities have emerged despite regime resilience?

    1. Economic Exhaustion: Nuclear and missile prioritisation diverts scarce resources from welfare.
    2. Demographic Shift: Over two-thirds of Iranians born post-Revolution reject clerical gerontocracy.
    3. Governance Alienation: Women and non-Shia minorities feel excluded due to clerical dominance.
    4. Kleptocracy Perception: Visible corruption at top echelons erodes regime legitimacy.

    How have foreign threats altered the internal dynamics of unrest?

    1. External Encouragement: U.S. and Israeli rhetoric emboldens agitators but lacks viable regime-change pathways.
    2. Deterrence Capacity: Iran retains retaliation capability despite losses in June 2025 conflict with Israel.
    3. Martyrdom Ethos: Cultural acceptance of sacrifice reduces deterrence effectiveness.
    4. Strategic Escalation: Closure threats to the Strait of Hormuz elevate global energy risks.

    Why are non-kinetic tools now preferred against Iran?

    1. Cyber Operations: Capitalises on Iran’s vulnerability to digital disruptions.
    2. Secondary Sanctions: Targets trade partners rather than direct military engagement.
    3. Financial Policing: Uses crypto-tracking to disrupt sanctions evasion networks.
    4. Limited Impact: China and UAE continue as top trading partners, accounting for over $70 billion in trade.

    Why does Iran’s crisis matter for India?

    1. Gulf Stability: Disruption affects India’s oil supplies, remittances, and diaspora security.
    2. Regional Balance: Enables Pakistan to project itself as an alternative security interlocutor.
    3. Domestic Linkages: India hosts around 25 million Shias, creating social and diplomatic sensitivities.
    4. Economic Opportunity: Post-sanctions revival could reopen strategic projects aligned with India’s connectivity vision.

    Conclusion

    The Iranian conundrum is no longer defined solely by regime-versus-protester dynamics. It reflects a complex interplay of economic collapse, elite consolidation, demographic alienation, and calibrated external pressure. While immediate regime collapse appears unlikely, the erosion of traditional stabilising pillars introduces long-term uncertainty with direct regional and global consequences.

  • Artificial Intelligence (AI) Breakthrough

    India must focus on AI and its environmental impact

    Why in the News?

    Artificial Intelligence is expanding rapidly across sectors. However, its environmental costs remain largely ignored in policy discussions. The global ICT sector contributes 1.8-2.8% of global greenhouse gas emissions, with estimates rising to 2.1-3.9%. For the first time, clear data is available on the energy, water, and carbon footprint of AI systems, including Large Language Models (LLMs).

    A clear gap exists between perceived digital efficiency and actual environmental impact. A single ChatGPT query consumes 10 times more energy than a Google search. Training one LLM can emit up to 3,00,000 kg of carbon dioxide. Despite these costs, India has no formal system to measure or disclose AI’s environmental impact. This contrasts with the EU and the US, highlighting a major governance gap.

    What is the scale of AI’s environmental footprint?

    1. Global ICT emissions: Accounts for 1.8-2.8% of global GHG emissions, with upper estimates reaching 3.9%.
    2. Carbon-intensive training: Training a single LLM can emit ~3,00,000 kg of carbon dioxide.
    3. Comparative impact: Emissions from one deep learning model equal emissions from five cars over their lifetime.
    4. Data gap: Carbon footprint data of AI models and users remains fragmented and inconsistent.

    How does AI affect energy consumption patterns?

    1. High energy intensity: Each ChatGPT query consumes 10× more energy than a Google search.
    2. Hidden electricity demand: AI workloads rely on energy-intensive data centres and specialised hardware.
    3. Misleading averages: Claims such as 0.24 watt-hours per AI query underestimate system-wide consumption.

    Why is water consumption emerging as a major concern?

    1. UNEP projection: AI data centres may consume 4.2-6.6 billion cubic metres of water by 2027.
    2. Cooling requirements: Water is extensively used to cool AI servers.
    3. Water security risks: High freshwater withdrawal threatens water-stressed regions.

    What global governance responses are emerging?

    1. UNESCO framework (2021): Recognises negative environmental impacts of AI; adopted by ~190 countries.
    2. European Union leadership:
      1. AI Act, 2024: Introduces environmental accountability in AI governance.
      2. Harmonised AI rules: Address sustainability alongside ethics and safety.
    3. United States approach: Sector-specific regulations addressing AI’s environmental externalities.

    Why does India need a regulatory shift?

    1. Unaccounted externalities: Environmental costs of AI development remain outside policy evaluation.
    2. Regulatory vacuum: No mandatory assessment of AI’s environmental impact.
    3. Climate obligations: AI expansion risks undermining India’s climate mitigation commitments.
    4. Policy imbalance: Focus on innovation without parallel sustainability safeguards.

    How can Environmental Impact Assessment be extended to AI?

    1. EIA framework: India’s EIA Notification, 2006 mandates environmental assessment for infrastructure projects.
    2. Proposed extension: Inclusion of AI development and deployment within EIA scope.
    3. Lifecycle evaluation: Assessment of energy use, water consumption, and emissions across AI lifespans.

    What role can disclosure standards play?

    1. ESG integration: Environmental impact of AI included under ESG disclosure norms.
    2. SEBI alignment: Disclosure of emissions from data centres and computing activities.
    3. EU precedent: Corporate Sustainability Reporting Directive (CSRD) mandates emission disclosure, including AI training.
    4. Transparency outcome: Enables informed policymaking and accountability.

    Which sustainable practices can mitigate AI’s impact?

    1. Pre-trained models: Reduces repeated energy-intensive training.
    2. Renewable energy: Powering data centres through clean energy sources.
    3. Efficiency reporting: Disclosure of AI-specific environmental metrics.
    4. Resource optimisation: Minimising water and energy intensity of AI infrastructure.

    Conclusion

    India’s AI ambitions must align with environmental sustainability. Institutionalising environmental assessment, disclosure norms, and sustainable practices is essential to prevent AI-driven ecological externalities. A regulatory framework that integrates innovation with environmental accountability will ensure AI remains a tool for inclusive and sustainable development.

  • Urban Transformation – Smart Cities, AMRUT, etc.

    Are India’s small towns being increasingly urbanised?

    Why in the News?

    India still focuses its urban future on megacities, even though only about 500 towns are large cities, while nearly 9,000 are small towns, most with populations below one lakh. Earlier, urbanisation was led mainly by metros, but this pattern is now changing. Small towns are increasingly absorbing surplus labour, migrant workers, and consumption activities as metros face high land prices, stressed infrastructure, and rising living costs. This shift reflects not inclusive growth, but the spread of urban crisis to smaller towns, with serious economic and social consequences.

    How have India’s small towns proliferated since the 1970s?

    1. Metropolitan Concentration: Organised capital accumulation during the 1970s-1990s prioritised large cities as centres of industry, infrastructure, and state investment.
    2. Labour Absorption: Cities like Delhi, Mumbai, Chennai, Kolkata, and later Bengaluru and Hyderabad absorbed surplus labour and expanded consumption.
    3. Spatial Fix: Metros functioned as spatial fixes for capitalism by enabling accumulation through land, infrastructure, and labour concentration.

    Why are India’s metros facing a crisis of over-accumulation today?

    1. Land Detachment: Land prices have become disconnected from productive economic use.
    2. Infrastructure Stress: Urban systems are stretched beyond functional limits.
    3. Cost Escalation: Rising housing and living costs have become unaffordable for working groups.
    4. Accumulation Limits: Metros have exhausted their capacity to absorb surplus capital and labour efficiently.

    Why have small towns emerged as new sites of urbanisation?

    1. Capital Redirection: Small towns offer cheaper land and lower entry barriers for capital.
    2. Labour Availability: They absorb migrants displaced from metros and rural youth exiting agrarian livelihoods.
    3. Functional Integration: Towns such as Sattenapalle (Andhra Pradesh), Dhamtari (Chhattisgarh), Barabanki (Uttar Pradesh), Hassan (Karnataka), Bongaigaon (Assam), and Una (Himachal Pradesh) now act as logistics nodes, agro-processing hubs, warehouse towns, service centres, and consumption markets.

    How are small towns embedded within the urban process?

    1. Urban Continuum: Small towns operate fully within urban capitalist systems rather than existing as rural-urban intermediaries.
    2. Regulatory Gaps: Weaker regulation and minimal political scrutiny facilitate capital expansion.
    3. Cost Arbitrage: Lower land prices and pliable labour make small towns attractive for accumulation under stress conditions.

    Are small towns a better alternative to metropolitan urbanisation?

    1. No Emancipatory Promise: The article rejects the notion that small towns ensure inclusive or equitable growth.
    2. Urbanisation of Poverty: What unfolds is the relocation of rural deprivation into urban spaces.
    3. Informal Labour Dominance: Construction workers without contracts, women in home-based work, and youth in platform economies face insecurity and lack of social protection.
    4. Emerging Hierarchies: Towns such as Bhadol (Madhya Pradesh) and Raichur (Karnataka) show consolidation of power among real estate brokers, contractors, micro-financiers, and local intermediaries controlling land and labour.

    What does this reveal about India’s urban policy framework?

    1. Metro-Centric Bias: Flagship urban missions remain focused on large cities.
    2. Policy Failure: Small towns remain under-governed despite being central to contemporary urbanisation.
    3. Political Neglect: Absence of adequate scrutiny deepens informalisation and inequality.

    Conclusion

    India’s small towns are not emerging as alternatives to the metropolitan crisis but as its extension. They represent a new spatial frontier for capitalist accumulation under stress, marked by informal labour, weak regulation, and entrenched local hierarchies. Without policy recalibration, small-town urbanisation risks reproducing the very inequalities it was expected to resolve.

    Greenwald Limit in Fusion Research

    Why in the News?

    China’s Experimental Advanced Superconducting Tokamak (EAST) fusion reactor has achieved stable plasma densities 30 to 65 percent higher than the Greenwald limit, overcoming a decades old constraint in nuclear fusion research.

    About Greenwald Limit

    • The Greenwald limit is a theoretical upper limit on plasma density in a tokamak fusion reactor.
    • It links the maximum stable plasma density to:
      • Plasma current
      • Size of the tokamak
    • Crossing this limit usually causes plasma instability and sudden collapse.

    Why the Greenwald Limit Matters?

    • Nuclear fusion requires:
      • Very high temperature
      • High plasma density
      • Sufficient confinement time
    • The Greenwald limit restricted how much fuel plasma could be packed into a tokamak.
    • It has been a major bottleneck to achieving self sustaining fusion or ignition.

  • Air Pollution

    Air Pollution Aerosols Intensify and Prolong Winter Fog Over North India: IIT Madras Study

    Why in the News

    A Indian Institute of Technology Madras led study published in Science Advances shows that air pollution aerosols are making winter fog over north India denser and longer lasting, worsening visibility and health impacts.

    About Aerosols

    • Aerosols are tiny solid or liquid particles suspended in the atmosphere.
    • They strongly influence air quality, weather and climate.
    • Natural sources: desert dust, sea spray, volcanic ash, forest fires
    • Human sources: vehicle emissions, industrial pollution, biomass burning, coal and diesel use
    • Primary aerosols are emitted directly.
    • Secondary aerosols form in the air from gases like sulphur dioxide and nitrogen oxides.

    Key Features

    • Extremely small size: penetrate deep into lungs and remain airborne easily
    • Persistence: stay suspended for days to weeks, travel long distances
    • Condensation nuclei: provide surfaces for water vapour to condense, aiding fog and cloud formation
    • Radiative effects:
      • Scatter sunlight: reflective aerosols cool the surface
      • Absorb heat: black carbon warms the atmosphere

    How Aerosols Affect Winter Fog

    • Increase number of fog droplets, making fog thicker
    • Reduce sunlight reaching the surface, causing cooling that sustains fog
    • Slow fog dissipation, leading to prolonged low visibility episodes

    Prelims Pointers

    • Aerosols act as condensation nuclei for fog and clouds
    • Black carbon absorbs heat while sulphate aerosols reflect sunlight
    • Human sources significantly amplify winter fog over north India
    • Aerosols influence health, visibility, weather and climate simultaneously
    [2019] In the context of which of the following do some scientists suggest the use of cirrus cloud thinning technique and the injection of sulphate aerosol into stratosphere? 

    (a) Creating the artificial rains in some regions 

    (b) Reducing the frequency and intensity of tropical cyclones 

    (c) Reducing the adverse effects of solar wind on the Earth

  • ISRO Missions and Discoveries

    PSLV-C62 Mission Failure

    Why in the News

    The Indian Space Research Organisation’s first launch of 2026, the PSLV-C62 mission, failed to place 16 satellites into the intended orbit on 12 January 2026. This marks the second consecutive failure of the Polar Satellite Launch Vehicle (PSLV), ISRO’s most reliable launch vehicle for over three decades.

    About PSLV-C62 Mission

    • Launch Vehicle: Polar Satellite Launch Vehicle
    • Payload: 16 satellites
      • Includes 7 foreign satellites
    • Mission outcome: Failed to reach intended orbit
    • Failure stage: Third stage (after successful completion of first two stages)

    Why the Failure Matters

    • PSLV is known as ISRO’s workhorse, with a long record of success since the 1990s.
    • This is the second straight PSLV failure, the first occurring in May 2025.
    • Consecutive failures raise concerns about reliability in the third stage, a critical phase of orbital insertion.

    Possible Cause of Failure

    • Exact cause not yet identified.
    • Based on the May 2025 failure, issues may relate to:
      • Drop in combustion chamber pressure in the third stage motor
      • Reduced thrust leads to insufficient acceleration needed to stabilise orbit
    • The Failure Analysis Committee report of the previous mission has not been made public.

    Why the Third Stage is Critical

    • The third stage provides high acceleration required to:
      • Maintain orbital velocity
      • Prevent premature orbital decay
    • Any pressure or thrust instability at this stage directly impacts mission success.

    PSLV: Four-Stage Configuration (Prelims Focus)

    1. First Stage
      • Solid propellant
      • Provides lift-off and overcomes gravity and atmospheric drag
      • Carries rocket to ~50–60 km altitude
    2. Second Stage
      • Liquid propellant
      • Improves velocity and stabilisation
    3. Third Stage
      • Solid motor
      • Provides rapid acceleration for orbital insertion
      • Most failure-prone stage in recent missions
    4. Fourth Stage
