Allahabad High Court on NSA Detention: Preventive Detention, Executive Discretion and Civil-Service Accountability
The Allahabad High Court's decision to quash the detention of Aakriti Chaudhary under the National Security Act (NSA), 1980 has become an important case concerning preventive detention, judicial review and accountability of public officials.
Chaudhary had been detained following a workers' protest in Noida in April 2026. A Bench of Justices Atul Sreedharan and Achal Sachdev found that the material relied upon by the authorities did not justify invoking the NSA and criticised the Gautam Buddha Nagar District Magistrate's decision as having been taken without proper application of mind.
The court directed payment of ₹5 lakh compensation, to be recovered from the salaries of officials found responsible, and ordered that its displeasure be entered in their service records.
The case is especially relevant for UPSC because it brings together Article 21, Article 22, preventive detention, public order, administrative discretion, judicial review and civil-service neutrality.
Why Is Preventive Detention Constitutionally Exceptional?
Ordinary criminal detention is primarily concerned with an offence that has already allegedly been committed.
Preventive detention has a different purpose: it seeks to prevent a person from engaging in anticipated conduct considered prejudicial to specified public interests.
The National Security Act, 1980 permits preventive detention on specified grounds connected with matters including the defence of India, security of India, security of a State, relations with foreign powers, maintenance of public order and maintenance of supplies and services essential to the community.
This gives the executive significant power over individual liberty. Consequently, courts insist upon strict observance of constitutional and statutory safeguards.
The constitutional framework is principally contained in Article 22.
Importantly, the ordinary safeguards under Article 22(1) and 22(2)—including production before a magistrate within 24 hours—do not apply in the same manner to persons detained under preventive-detention laws because Article 22(3) expressly creates an exception.
But preventive detention is not beyond constitutional protection. Article 22 itself provides safeguards, and detention remains subject to judicial review, particularly under Articles 32 and 226, as well as the guarantee of personal liberty under Article 21.
Who Can Order Detention Under the NSA?
Under Section 3 of the NSA, the Central or State Government can make a detention order when the statutory conditions are satisfied.
The State Government may also empower a District Magistrate or Commissioner of Police, for a specified period and area, to exercise detention powers where circumstances warrant it.
Therefore, it is inaccurate to understand an NSA detention simply as an ordinary police arrest. It is an executive preventive-detention order authorised by statute.
The Act also creates procedural safeguards. The grounds of detention must ordinarily be communicated to the detainee, who must receive the earliest opportunity to make a representation.
Cases must also be placed before an Advisory Board. Under the NSA, the government must ordinarily place the detention and relevant material before the Board within three weeks of detention, and the Board must submit its report within seven weeks from the date of detention.
Law and Order, Public Order and Security of the State
This distinction is particularly important for Prelims and Mains.
These concepts can be visualised as progressively narrower circles:
Law and order → Public order → Security of the State
A local disturbance or individual offence may create a law-and-order problem without disrupting the life of the wider community.
Public order concerns disturbances having a broader impact on the community or public tranquillity.
Security of the State represents a still more serious category involving threats to the State itself.
Therefore, not every protest, clash or criminal offence automatically becomes a threat to public order, much less to the security of the State.
This distinction is critical because preventive-detention powers cannot legitimately be invoked merely by attaching a more serious label to conduct that does not satisfy the statutory threshold.
Judicial Review as a Check on Executive Power
Preventive detention gives the executive unusually broad authority because action is taken to prevent anticipated conduct rather than following conviction through an ordinary criminal trial.
Judicial review therefore becomes a crucial constitutional safeguard.
High Courts can exercise their jurisdiction under Article 226, including issuing a writ of habeas corpus, while the Supreme Court's fundamental-rights jurisdiction is available under Article 32.
However, it would be incorrect to say that habeas corpus is the only protection available to an NSA detainee. The Constitution and the NSA also provide procedural protections involving communication of grounds, representation against detention and scrutiny by an Advisory Board.
Courts can examine questions such as whether:
the competent authority actually applied its mind;
relevant material existed to support the detention;
statutory and constitutional procedures were followed;
irrelevant considerations influenced the decision; and
the detention was arbitrary or mala fide.
In Chaudhary's case, the High Court concluded that her detention violated personal liberty and strongly criticised the administrative decision-making involved.
Civil-Service Neutrality and Constitutional Loyalty
The judgment also has a wider administrative significance.
The High Court stressed that IAS and IPS officers must remember that their allegiance is to the Constitution and law rather than unquestioning obedience to the political executive.
Civil-service neutrality does not mean refusing to implement the policies of an elected government. Democratic accountability requires civil servants to faithfully implement lawful government policy.
But the permanent executive is also bound by the Constitution and cannot treat political instructions as a defence for an unlawful exercise of statutory power.
This creates an important distinction:
Political executive determines lawful policy → civil service implements it impartially → Constitution and law limit both.
The case therefore illustrates why reasoned decision-making, proportionality, accountability and judicial review are important controls over administrative discretion.
What Did the Court Mean by “Orwellian Dystopia”?
“Orwellian” derives from the writings of George Orwell, particularly his novel Nineteen Eighty-Four (1984).
An Orwellian dystopia generally describes a society characterised by oppressive state power, pervasive control, suppression of dissent and erosion of individual freedom.
The High Court used the expression while warning about the consequences of unchecked bureaucratic abuse of coercive powers.
It should therefore be understood as a judicial warning about arbitrary state power, rather than as a technical constitutional or statutory term.
One current procedural development should also be noted: on September 9, 2026, the Uttar Pradesh government told the Supreme Court that it intends to challenge the High Court's order. The High Court ruling is therefore significant, but the litigation may not be over.
Prelims Quick Revision
National Security Act (NSA): enacted in 1980.
It is a preventive-detention law.
Preventive detention seeks to prevent anticipated prejudicial conduct rather than punish a person after conviction for a past offence.
Article 21: protection of life and personal liberty.
Article 22: constitutional provisions concerning arrest and detention, including preventive detention.
Article 22(3): creates exceptions from Article 22(1) and (2) for enemy aliens and persons detained under preventive-detention laws.
Article 22(5): requires communication of grounds and earliest opportunity to make a representation.
Under NSA Section 3, detention powers primarily lie with the Central/State Government; a State Government can empower a District Magistrate or Commissioner of Police subject to statutory conditions.
NSA cases are subject to review by an Advisory Board.
The Advisory Board consists of three persons who are, have been, or are qualified to be appointed as High Court judges; its chairperson must be a person who is or has been a High Court judge.
Article 226: High Courts' writ jurisdiction.
Article 32: Supreme Court remedy for enforcement of Fundamental Rights.
Habeas corpus: judicial remedy against unlawful detention.
Law and order, public order and security of the State are not synonymous.
Preventive-detention powers remain subject to constitutional and judicial scrutiny.
Possible Mains Question
Preventive detention represents an exceptional exercise of executive power in a constitutional democracy and therefore requires strict procedural safeguards and effective judicial review. Discuss with reference to the National Security Act, 1980, and explain the role of civil-service neutrality in preventing arbitrary exercise of administrative power.
BRICS Summit 2026: India-China Trade, Technology Curbs and the Global Supply-Chain Challenge
Ahead of the 18th BRICS Summit in New Delhi, scheduled for September 12–13, 2026, India is preparing to raise trade and investment concerns with China, particularly restrictions affecting access to critical technologies, components and raw materials needed by Indian manufacturing.
The issue illustrates a larger dilemma in India-China economic relations: China is simultaneously a major source of industrial inputs for India and a source of strategic supply-chain vulnerability.
BRICS therefore gives India a platform to combine bilateral economic diplomacy with its wider agenda of resilient supply chains and greater representation for the Global South.
India holds the BRICS Chairship in 2026, under the theme “Building Resilience, Innovation, Cooperation and Sustainability.”
Why China Matters to Indian Manufacturing
Indian manufacturing remains dependent on Chinese inputs in several strategically important sectors, including electronics, machinery, solar-energy equipment, batteries, active pharmaceutical ingredients and critical minerals.
The immediate concern is China's tighter controls and procedural restrictions involving certain technology-intensive exports.
Indian industry has already faced difficulties arising from delays in supplies of rare-earth magnets, while concerns have also emerged around battery technologies, renewable-energy supply chains and specialised power-transmission equipment.
Rare-earth materials are particularly important because permanent magnets containing elements such as neodymium and dysprosium are used in electric vehicles, renewable-energy equipment, electronics and advanced industrial applications.
Recent Chinese licensing restrictions have affected buyers in India and other major economies.
This creates a strategic problem:
Indian manufacturing expansion → greater demand for sophisticated inputs → dependence on concentrated Chinese supply chains → vulnerability to export controls or geopolitical disruptions.
The solution is therefore not simply to stop importing from China. India needs to diversify suppliers while simultaneously building domestic technological and manufacturing capabilities.
Global Value Chains and the Question of Resilience
A Global Value Chain (GVC) exists when different stages in producing a good or service are distributed across several countries.
For example:
Raw materials → Country AComponents → Country BAssembly → Country CDesign/technology → Country DFinal market → multiple countries
Participation in GVCs can increase exports, productivity, technology diffusion and employment. But excessive concentration of critical stages in one country creates vulnerabilities.
For India, the objective should therefore be to move into higher-value segments such as advanced manufacturing, product design, R&D and sophisticated components rather than remaining concentrated primarily in low-value assembly.
Policies involving domestic manufacturing, logistics infrastructure, skilled labour, R&D, trade agreements and diversification of critical-mineral sources can help achieve this.
Supply-chain resilience does not necessarily mean complete self-sufficiency.
It means reducing dangerous single-source dependencies and ensuring alternative sources and domestic capabilities exist when disruptions occur.
Reciprocity in India-China Economic Relations
India is also likely to emphasise reciprocity.
In international economic relations, reciprocity broadly means that countries provide reasonably comparable market access and treatment to each other's businesses.
India has itself imposed additional scrutiny on investment originating from countries sharing a land border.
At the same time, Indian businesses have raised concerns about market access and regulatory and sourcing restrictions in China.
The policy question is therefore how both sides can progressively remove restrictions while protecting legitimate national-security interests.
For India, economic engagement with China increasingly involves balancing three objectives:
trade and investment opportunities + manufacturing requirements + national and economic security.
This is why complete economic disengagement is difficult, while unchecked dependence is also undesirable.
Why BRICS Matters for India
BRICS has changed considerably from the original grouping.
The term BRIC was coined in 2001 in a Goldman Sachs paper referring to Brazil, Russia, India and China.
Political cooperation subsequently developed, with the first BRIC summit held at Yekaterinburg, Russia, in 2009.
South Africa joined the grouping and participated in its first summit as a member at Sanya in 2011, creating BRICS.
A major expansion began in 2024. Egypt, Ethiopia, Iran and the United Arab Emirates became full members from January 1, 2024, and Indonesia became a full member in January 2025.
Official Indian documents describe today's BRICS as comprising 11 full members and 10 partner countries.
The expanded grouping—sometimes informally described as BRICS+ or “BRICS 2.0”—therefore gives India a platform involving major emerging economies, energy producers and countries from Asia, Africa, Latin America and West Asia.
Its cooperation broadly operates through three pillars: political and security cooperation, economic and financial cooperation, and cultural/people-to-people exchanges.
Fortaleza Declaration and the New Development Bank
The 6th BRICS Summit, held in Fortaleza, Brazil, in 2014, was particularly significant for institutional development.
BRICS leaders agreed to establish the New Development Bank (NDB) and the Contingent Reserve Arrangement (CRA).
The NDB was designed to mobilise resources for infrastructure and sustainable-development projects in BRICS and other emerging/developing economies.
The CRA created a financial safety-net arrangement intended to help participating countries address short-term balance-of-payments pressures.
BRICS, China and India’s Global South Strategy
BRICS presents India with both an opportunity and a strategic challenge.
India can use the grouping to advocate reforms of global institutions, stronger representation for developing economies, climate finance, digital governance and more resilient economic networks.
India's 2026 presidency has explicitly highlighted institutional reform, climate finance, digital governance and strengthening the voice of the Global South.
At the same time, China has substantially greater manufacturing capacity and economic weight in several areas.
India therefore has an interest in ensuring that BRICS does not simply reproduce existing economic dependencies within a grouping ostensibly designed to strengthen developing economies.
India's objective is consequently broader than resolving individual customs restrictions. It involves using BRICS to promote diversified supply chains, technology cooperation, investment and greater economic resilience, while continuing bilateral engagement with China where Indian interests require it.

HVDC: High Voltage Direct Current; particularly useful for efficient long-distance bulk electricity transmission and integration of geographically dispersed renewable energy.
Rare-earth permanent magnets are important inputs for EVs, renewable energy, electronics and advanced manufacturing.
Possible Mains Question
China's importance to Indian manufacturing makes complete economic disengagement impractical, while dependence on concentrated Chinese supply chains creates strategic vulnerabilities. In this context, examine how India can use platforms such as BRICS to promote resilient global value chains while safeguarding its strategic and technological autonomy.
Swachh Vayu Sarvekshan 2026: Why Lucknow Topped the Ranking Despite PM10 Remaining Above the Standard
Lucknow ranked first among million-plus cities in Swachh Vayu Sarvekshan 2026, followed by Indore and Jabalpur. The ranking recognised measures such as mechanised road sweeping, electric vehicles for waste collection, management of legacy waste and action against major sources of urban air pollution.
However, the result needs an important qualification: Swachh Vayu Sarvekshan is not a ranking of which city has the lowest AQI or cleanest ambient air on a particular day. It primarily assesses cities' performance and actions to reduce air pollution under the National Clean Air Programme (NCAP).
Swachh Vayu Sarvekshan vs AQI
The Swachh Vayu Sarvekshan, launched by the Ministry of Environment, Forest and Climate Change (MoEFCC), evaluates cities on measures addressing major pollution sources such as road dust, construction and demolition waste, municipal solid waste and biomass burning, vehicles and industries, along with improvement in air quality.
Cities are assessed through self-evaluation, state-level scrutiny, CPCB evaluation and field verification.
The Air Quality Index (AQI) serves a different purpose. It communicates ambient air quality based on measured concentrations of pollutants and their potential health implications.
Therefore:
Swachh Vayu Sarvekshan → evaluates pollution-control performance and interventions
AQI → indicates actual ambient air quality over a specified period
This explains how Lucknow can top the Sarvekshan while still having particulate pollution above the prescribed national standard.
Why Lucknow’s PM10 Figure Matters
Lucknow's annual PM10 concentration has reportedly declined from around 250 µg/m³ in 2017-18 to 137 µg/m³, demonstrating substantial improvement. But 137 µg/m³ is still more than twice the National Ambient Air Quality Standards (NAAQS) annual PM10 limit of 60 µg/m³.
This distinction is important.
A city can perform strongly in implementing pollution-control measures and show a substantial reduction from its historical pollution level without yet having achieved clean air according to national standards.
The ranking is therefore meaningful as an indicator of progress and governance performance, but it should not be interpreted as proof that the winning city has safe or satisfactory air quality.
PM10 vs PM2.5
Particulate Matter (PM) consists of tiny solid particles and liquid droplets suspended in the atmosphere.
PM10 refers to particles with an aerodynamic diameter of 10 micrometres or less. Important urban sources include road and construction dust, industrial activity and combustion.
PM2.5 consists of much finer particles with a diameter of 2.5 micrometres or less. Important sources include combustion from vehicles, industries, power generation, biomass burning and secondary particles formed through atmospheric chemical reactions.
PM2.5 is particularly concerning because its small size enables particles to penetrate deep into the respiratory system and is associated with serious health risks.
For India's NAAQS, the annual limits are:
PM10 → 60 µg/m³PM2.5 → 40 µg/m³
Why Road Dust and Waste Management Matter
Urban air-pollution discussions frequently focus on vehicle exhaust, but India's pollution problem is multi-source.
Road dust can be repeatedly resuspended by moving vehicles. Construction and demolition activities generate coarse particulate matter. Open burning of municipal waste produces particulate matter and other pollutants. Industrial activity, diesel generators and transport add further emissions.
This explains why Lucknow's interventions included mechanised sweeping, waste-management measures, cleaner municipal vehicles and expansion of green spaces. The city scored 198 points, narrowly ahead of Indore's 197 and Jabalpur's 195.
National measures also include BS-VI vehicle standards, EV promotion and charging infrastructure.
National Clean Air Programme and the Limits of City-Based Action
The National Clean Air Programme (NCAP) was launched in 2019 as India's principal national framework for reducing air pollution across identified cities. Swachh Vayu Sarvekshan creates competition among NCAP cities by evaluating implementation of their clean-air measures.
But air pollution does not respect municipal boundaries.
Pollutants can move across districts and states through atmospheric circulation.
Agricultural residue burning, industries, thermal power plants, transport corridors and dust originating outside a city's administrative boundary can influence urban air quality.
This is why airshed-based management is increasingly important.
An airshed is a geographical region sharing common patterns of air movement and pollution, meaning effective pollution control may require cooperation across multiple cities and states rather than isolated municipal action.
MoEFCC has itself worked on an airshed approach for air-quality management in the Indo-Gangetic Plain, emphasising interstate and institutional coordination.
Thus, city rankings can encourage better municipal governance, but sustained improvement requires:
city action + regional coordination + source-specific emission reduction + reliable monitoring + public participation.
Defence Acquisition Council Clears ₹1.10 Lakh Crore Proposals: How India’s Defence Procurement System Works
The Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh, granted Acceptance of Necessity (AoN) on September 7, 2026, for capital acquisition proposals worth about ₹1.10 lakh crore for the Armed Forces.
Significantly, the Ministry of Defence says approximately 98% of the procurements covered by these AoNs are intended to come from Indian industry, linking military modernisation with defence indigenisation.
However, an AoN should not be confused with a final purchase order.
It is essentially the in-principle administrative approval of the need for an acquisition; procurement must subsequently pass through further stages before a contract is signed.
What Has the DAC Approved?
For the Indian Army, AoN was granted for Chemical, Biological, Radiological and Nuclear (CBRN) Recce Vehicles, High Mobility Vehicles, Self-Propelled Mechanical Mine Layers, Advanced Light Helicopters, Trawl Tanks and the Sarvatra Bridge System.
These systems perform different battlefield functions. CBRN reconnaissance vehicles detect, identify, monitor and mark contaminated areas; high-mobility vehicles improve logistics and movement in difficult terrain; mechanical mine layers enable rapid mine-laying; while trawl tanks and bridge systems help fighting formations overcome obstacles and establish crossings.
Other approved requirements include systems such as Arudhra radars, Marine Gas Turbines and Ground-Based Multi-Purpose Jammers, strengthening surveillance, naval propulsion and electronic-warfare capabilities.
DAC, AoN and the Defence Acquisition Process
The Defence Acquisition Council is one of the highest decision-making bodies in the Ministry of Defence for capital acquisitions.
It is chaired by the Defence Minister and was established following defence-management reforms after the Kargil conflict.
Its role includes giving policy direction and taking decisions on major capital procurement proposals for the Armed Forces.
For UPSC, the sequence matters more than memorising every procedural stage:
Operational requirement → Acceptance of Necessity (AoN) → tender/RFP and vendor process → technical and commercial evaluation → approvals → contract → delivery
Thus:
AoN ≠ contract ≠ final order.
A project receiving AoN can subsequently be modified, delayed or even fail to result in a contract.
India's earlier Defence Procurement Procedure (DPP) has also been replaced by the broader Defence Acquisition Procedure (DAP) 2020.
DAP 2020 seeks to streamline capital acquisition while increasing indigenous content and encouraging domestic design and manufacturing.
Why Indigenisation Matters
India's defence-procurement policy increasingly seeks to combine two objectives:
military modernisation + domestic defence-industrial capacity.
Domestic production can reduce vulnerability to foreign supply disruptions, improve maintenance and availability during conflict, preserve strategically important technologies within India and create an industrial ecosystem involving public-sector enterprises, private firms and MSMEs.
But indigenisation cannot simply mean assembling imported components in India. Long-term strategic autonomy requires increasing domestic capabilities in design, R&D, propulsion, sensors, electronics, materials, weapons and critical components.
The latest DAC decision is significant in this context because the Defence Ministry says roughly 98% of the proposed procurement by value will be sourced from Indian industry.
India Remains a Major Arms Importer
The push for indigenisation has reduced some import dependence, but India remains a major buyer of foreign military equipment.
According to SIPRI, India was the world's second-largest recipient of major arms during 2021–25, accounting for 8.2% of global arms imports.
India's imports nevertheless declined by about 4% compared with 2016–20, partly reflecting growing domestic design and production capacity.
There has also been significant diversification of suppliers. Russia's share of India's major arms imports declined from 70% in 2011–15 to 51% in 2016–20 and 40% in 2021–25, while India increasingly sourced equipment from countries including France, Israel and the United States.
This shows why indigenisation and diversification need to proceed simultaneously: domestic capability cannot replace every foreign requirement immediately, particularly in advanced platforms and technologies.
Defence Spending: Recalibration Rather Than a Simple Cut?
Defence spending involves an unavoidable opportunity cost because public resources are also required for infrastructure, health, education and social protection.
But the relevant policy question is not simply whether defence expenditure is “high” or “low”.
According to SIPRI, India spent approximately $92.1 billion on its military in 2025, making it the fifth-largest military spender globally.
This represented an 8.9% real increase over 2024.
The quality and composition of expenditure therefore matter.
Capital expenditure on modernisation, R&D and domestic production can have different long-term consequences from expenditure dominated by imports or recurring costs.
A sustainable strategy requires balancing:
operational preparedness + modernisation + fiscal sustainability + indigenous R&D + domestic manufacturing.
Prelims Quick Revision
DAC: Defence Acquisition Council.
Chairperson: Union Defence Minister.
DAC is a major decision-making body for capital defence acquisitions.
AoN: Acceptance of Necessity — in-principle administrative approval for an acquisition.
AoN does not mean that a contract has been signed.
September 2026 DAC proposals: approximately ₹1.10 lakh crore.
Around 98% of the procurement covered by these AoNs is intended from Indian industry.
DPP has been superseded by Defence Acquisition Procedure (DAP) 2020.
Arudhra: indigenous 4D multifunction phased-array surveillance radar developed by DRDO.
Sarvatra: mobile bridging system used to facilitate battlefield crossings.
SIPRI ranks India as the second-largest recipient of major arms in 2021–25, with an 8.2% global share.
India was the fifth-largest military spender in 2025, at an estimated $92.1 billion.
Do not confuse military expenditure, defence capital acquisition and arms imports; they measure different things.
EOS-05 in Geosynchronous Orbit: Why India’s New Earth-Observation Satellite Is Different
ISRO's EOS-05, launched aboard GSLV-F17 on September 4, 2026, has reached its intended geosynchronous orbit after three orbit-raising manoeuvres. On September 7, ISRO fired the satellite's Liquid Apogee Motor (LAM) for 1,247 seconds, raising it to an estimated 34,903 km × 35,884 km orbit. ISRO reported the spacecraft to be healthy.
EOS-05 is significant because ISRO describes it as India's first imaging satellite from geosynchronous orbit. Most Earth-observation satellites operate much closer to Earth in Low Earth Orbit (LEO), often in polar or Sun-synchronous orbits.
Why Put an Earth-Observation Satellite So High?
A satellite in Low Earth Orbit can produce detailed observations because it operates relatively close to Earth.
But it moves rapidly relative to the surface, so any particular location remains within its field of view only for a limited period before the satellite must revisit it.
A geosynchronous satellite has an orbital period matching Earth's rotation—approximately 24 hours.
This allows it to maintain prolonged observation of a broad geographical region.
EOS-05 can therefore provide persistent, high-frequency observation of the Indian subcontinent, complementing rather than replacing India's LEO Earth-observation satellites.
Such capability can be valuable for weather monitoring, disaster management, rapidly evolving events and strategic surveillance.
Geosynchronous Is Not Necessarily Geostationary
This distinction is important for Prelims.
A geosynchronous orbit (GSO) is one in which the satellite's orbital period is equal to Earth's rotational period.
But its orbit can be inclined or slightly elliptical, meaning the satellite does not necessarily appear completely stationary to an observer on Earth.
A geostationary orbit (GEO) is a special type of geosynchronous orbit that is:
circular + above the equator + moving in the same direction as Earth's rotation + orbital period equal to Earth's rotation.
A geostationary satellite therefore appears fixed over a particular longitude.
EOS-05's final orbit is approximately 34,903 × 35,884 km, so it is slightly elliptical rather than perfectly circular.
ISRO had earlier stated that the spacecraft would ultimately be positioned in GSO at the 85.5° East orbital slot.
Thus, all geostationary orbits are geosynchronous, but all geosynchronous orbits are not geostationary.
Why Didn't GSLV Place EOS-05 Directly in Its Final Orbit?
EOS-05 was not launched directly into its operational geosynchronous orbit. GSLV-F17 initially placed it into a Sub-Geosynchronous Transfer Orbit (Sub-GTO).
This approach saves launch-vehicle energy.
Taking a heavy spacecraft directly from Earth's surface to a nearly circular orbit around 36,000 km altitude requires considerable energy and propellant.
Instead:
Rocket launches satellite → Sub-GTO/GTO → satellite separates → onboard propulsion raises orbit → final operational GSO
EOS-05 subsequently used its own LAM propulsion system for orbit raising.
After the first manoeuvre on September 5, its orbit was approximately 20,000 km × 31,129 km. The second manoeuvre on September 6 raised the apogee to about 35,786 km.
The final September 7 burn raised the perigee and produced the approximately 34,903 km × 35,884 km orbit.
LEO, MEO and GEO: Know the Basic Orbits
Low Earth Orbit (LEO) generally extends to around 2,000 km altitude. The International Space Station and many Earth-observation satellites operate in LEO.
A polar orbit is usually a relatively low-altitude orbit in which a satellite travels roughly from pole to pole. As Earth rotates underneath, the satellite can progressively observe much of the planet.
A Sun-synchronous orbit (SSO) is a special near-polar orbit designed so that the satellite crosses a given location at approximately the same local solar time, useful for comparing Earth images under similar lighting conditions.
Medium Earth Orbit (MEO) lies between LEO and geosynchronous altitude. Navigation satellite systems commonly use this region.
Geosynchronous/Geostationary orbit operates at approximately 35,786 km altitude for a circular equatorial geostationary orbit. It is widely used for communications and meteorological observation.
The choice of orbit therefore depends on the mission:
LEO/polar → detailed and global Earth observationMEO → commonly navigationGEO/GSO → communications, weather and persistent regional observation
Why EOS-05 Matters for India
EOS-05 does not make conventional polar-orbiting Earth-observation satellites obsolete. Instead, the two architectures provide complementary capabilities.
LEO satellites: closer to Earth, generally capable of high-resolution observation, but periodically revisit locations.
Geosynchronous imaging: much farther away, but capable of repeatedly observing a very large region for long periods.
The strategic value lies in reducing the time gap between successive observations of rapidly changing events.
EOS-05 also marks the successful return of India's GEO-imaging objective after GSLV-F10/EOS-03 failed in August 2021 because of a cryogenic upper-stage anomaly.
ISRO's official mission records list EOS-03 as unsuccessful, while EOS-05 is now described as India's first imaging satellite from geosynchronous orbit.
Prelims Quick Revision
EOS-05: state-of-the-art Earth-observation spacecraft developed by ISRO.
Launch: September 4, 2026 aboard GSLV-F17.
ISRO describes EOS-05 as India's first imaging satellite from geosynchronous orbit.
Final estimated orbit after September 7 manoeuvre: 34,903 km × 35,884 km.
Final LAM burn: 1,247 seconds.
Planned orbital slot: 85.5° East.
GSLV: Geosynchronous Satellite Launch Vehicle.
GSLV-F17 initially placed EOS-05 in a Sub-Geosynchronous Transfer Orbit.
LAM: Liquid Apogee Motor, used for spacecraft orbit-raising manoeuvres.
Perigee: point in an Earth orbit nearest Earth.
Apogee: point farthest from Earth.
LEO: broadly up to about 2,000 km above Earth.
Polar orbit: passes approximately over Earth's polar regions, enabling broad/global coverage as Earth rotates beneath it.
Sun-synchronous orbit: near-polar orbit that crosses locations at approximately the same local solar time.
Geosynchronous orbit: orbital period matches Earth's rotation.
Geostationary orbit: circular, equatorial geosynchronous orbit in which a satellite appears stationary relative to Earth.
Geostationary altitude is approximately 35,786 km above the equator.
All geostationary satellites are geosynchronous, but not all geosynchronous satellites are geostationary.
GTO is primarily a transfer orbit used to reach a final geosynchronous/geostationary orbit.
Possible Mains Question
Most Earth-observation satellites traditionally operate in Low Earth or polar orbits, while EOS-05 has been designed for imaging from geosynchronous orbit. Explain the differences between polar, geosynchronous and geostationary orbits, and discuss how geosynchronous Earth observation can complement conventional LEO-based satellite systems.
Antibiotic-Resistant Infections in India: Why Carbapenem Resistance Is a Major Health Threat
A large multicentre Indian study has provided direct evidence that carbapenem-resistant Gram-negative bacterial infections are associated with higher mortality and substantially greater treatment costs than infections caused by susceptible strains of the same bacteria.
The ICMR-supported study analysed 159,336 hospitalised patients across 20 tertiary-care hospitals between April 2022 and April 2025. Of these, 26,213 had confirmed Gram-negative bacterial infections, and 16,025—or 61.1%—were carbapenem-resistant.
What Did the ICMR Study Find?
Researchers studied four important Gram-negative pathogens: Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa.
For all four, carbapenem-resistant infections were associated with a greater risk of death than susceptible infections. The relative risk of mortality was 1.41 for E. coli, 1.33 for K. pneumoniae, 1.16 for A. baumannii and 1.43 for P. aeruginosa.
The situation was particularly serious for bloodstream infections caused by carbapenem-resistant non-fermenting bacteria, where mortality reached approximately 46.4%–50.8%.
Resistance also imposed an economic burden: antibiotic-treatment costs for resistant infections were approximately 1.1 to 2 times higher than for susceptible infections.
The findings show that AMR is not merely a laboratory measure of whether a drug kills a bacterium—it can directly affect survival, hospital treatment and healthcare expenditure.
Antibiotic Resistance vs Antimicrobial Resistance
These terms should not be used interchangeably.
Antibiotic resistance specifically refers to bacteria becoming resistant to antibiotics designed to treat bacterial infections.
Antimicrobial resistance (AMR) is broader. It occurs when microorganisms—including bacteria, viruses, fungi and parasites—no longer respond adequately to medicines used against them.
Therefore:
Antibiotic resistance ⊂ Antimicrobial resistance
Antibiotics also do not treat viral infections such as ordinary viral colds and influenza.
What Are Gram-Negative Bacteria?
“Gram-negative” refers to how bacteria respond to the Gram staining technique, which reflects differences in bacterial cell-wall structure.
Gram-negative bacteria possess an outer membrane in addition to a thin peptidoglycan layer. This outer membrane can act as an additional barrier against some antimicrobial drugs.
Major clinically important Gram-negative bacteria include:
E. coli — commonly associated with urinary-tract and bloodstream infections;
Klebsiella pneumoniae — pneumonia, bloodstream and other healthcare-associated infections;
Acinetobacter baumannii — particularly important in hospital and intensive-care settings; and
Pseudomonas aeruginosa — can cause serious infections, particularly in vulnerable patients.
The ICMR study focused on these four pathogens.
Why Is Carbapenem Resistance Particularly Concerning?
Carbapenems are a class of broad-spectrum beta-lactam antibiotics used particularly for serious bacterial infections, including infections caused by organisms resistant to several other antibiotics.
Examples include meropenem, imipenem and ertapenem.
When Gram-negative bacteria develop carbapenem resistance, an important therapeutic option becomes ineffective, leaving clinicians with fewer choices.
Resistance can arise through mechanisms including production of carbapenemase enzymes, changes in bacterial permeability and efflux mechanisms.
This can force doctors to use alternative or newer treatments that may be more expensive, less accessible or associated with other clinical limitations.
The Indian study found that carbapenem-resistant E. coli and K. pneumoniae were predominantly treated with ceftazidime-avibactam rather than polymyxin B, illustrating how resistance can alter treatment choices.
Why AMR Is a One Health Problem
AMR cannot be controlled exclusively inside hospitals.
Antimicrobials are used across human healthcare, veterinary medicine and food production. Resistant organisms and resistance genes can circulate among humans, animals and the environment through food systems, wastewater, sewage, soil and water.
This is the basis of the One Health approach, which recognises that the health of humans, animals, plants and ecosystems is interconnected.
India's National Action Plan on Antimicrobial Resistance 2.0 (2025–2029) explicitly embeds this One Health approach and seeks coordination across human health, animal health, agriculture and environmental sectors.
Globally, the World Health Assembly adopted an updated Global Action Plan on AMR 2026–2036 in May 2026, strengthening the One Health framework. It was developed through the Quadripartite partnership involving WHO, FAO, UNEP and WOAH.
Surveillance, Diagnostics and Antimicrobial Stewardship
Three interventions are particularly important.
Surveillance identifies which pathogens are becoming resistant, where resistance is spreading and which drugs remain effective. Integrated surveillance should cover human, animal and environmental sectors. WHO's 2026 One Health surveillance guidance specifically emphasises comparable data collection and analysis across sectors.
Diagnostics help identify the pathogen and its antimicrobial susceptibility. Better and faster diagnostics can reduce unnecessary broad-spectrum antibiotic use and allow clinicians to select more appropriate therapy.
Antimicrobial stewardship means systematically ensuring that antimicrobials are used appropriately—the right drug, dose, route and duration for the right patient, based wherever possible on clinical and diagnostic evidence.
These measures must operate alongside infection prevention and control, vaccination, sanitation, clean water, hospital hygiene and responsible antimicrobial use in animals and agriculture.
The objective is not simply to develop stronger antibiotics. It is to preserve the effectiveness of existing medicines while preventing resistant infections from emerging and spreading.

Dogri Script Revival in Jammu: Language, Eighth Schedule and India’s Linguistic Diversity
Public signboards in Jammu have begun displaying place names in Namey Dogra Akhar, alongside Devanagari and Roman scripts, as part of an effort to revive the traditional script associated with the Dogri language.
The initiative is significant because Dogri itself is constitutionally recognised and widely written in Devanagari, while its historical script gradually fell out of everyday and official use.
The revival therefore concerns not merely a language but the preservation of a distinct writing tradition and cultural heritage.
What Is Dogri?
Dogri is an Indo-Aryan language, generally classified within the Western Pahari group.
It is primarily associated with the Dogra cultural region centred on Jammu, with speakers also present in adjoining areas.
According to the 2011 Census, India had 2,596,767 Dogri speakers, of whom about 2.51 million were recorded in the then State of Jammu and Kashmir.
Dogri also has two important forms of legal recognition.
First, it is one of the 22 languages in the Eighth Schedule of the Constitution.
Second, under the Jammu and Kashmir Official Languages Act, 2020, Kashmiri, Dogri, Urdu, Hindi and English are official languages of the Union Territory of Jammu and Kashmir.
Dogri and the 92nd Constitutional Amendment
Dogri was not part of the Constitution's original list of scheduled languages.
The 92nd Constitutional Amendment Act, 2003 added four languages:
Bodo + Dogri + Maithili + Santhali
This increased the number of languages in the Eighth Schedule from 18 to 22.
For UPSC, remember the distinction between a language and a script.
Constitutional recognition of Dogri does not mean the Constitution prescribes Namey Dogra Akhar as its mandatory script. Dogri is now predominantly written and taught in Devanagari.
What Is Namey Dogra Akhar?
Namey Dogra Akhar, meaning roughly “New Dogra Script”, developed from the older Takri script, historically used for Dogri and related languages in the western Himalayan region.
During the rule of Maharaja Ranbir Singh, who became ruler of Jammu and Kashmir in 1856, the existing script was modified, including through incorporation of vowel forms influenced by Devanagari, to make it more suitable for administrative use.
The resulting modified writing system came to be known as Namey Dogra Akhar.
It was used in official and administrative work alongside Persian during the Dogra period.
Why Did the Script Decline?
The decline occurred gradually rather than through a single event.
Under Maharaja Pratap Singh, Urdu replaced Persian as an important official administrative language, reducing the institutional space available to Dogri's traditional script.
Another important transition occurred in 1944, when the literary organisation Dogri Sanstha adopted Devanagari for promoting Dogri literature.
This helped make Dogri literature accessible through a widely used script and supported the language's literary development. Dogri subsequently received Sahitya Akademi recognition in 1969.
But there was a trade-off: as Dogri education and publishing increasingly adopted Devanagari, fewer people learned Namey Dogra Akhar.
Institutional development continued around the language—including university teaching, literature and ultimately constitutional recognition—but largely through Devanagari rather than the historical script.
This explains the present situation:
Dogri language survived and expanded institutionally → Devanagari became dominant → traditional Dogri script declined.
Why Does Script Revival Matter?
A script is more than a mechanism for recording speech. Historical scripts can contain manuscripts, administrative records, inscriptions, literature and collective cultural memory.
If knowledge of a script disappears, future generations may become dependent on specialists to access historical material written in it.
Public signboards provide one relatively simple method of increasing visual familiarity with a traditional script. But meaningful revival would require more than signage.
Digitisation of manuscripts, Unicode/digital support, fonts and keyboards, educational material, academic research and voluntary opportunities to learn the script would also matter.
At the same time, preservation need not require replacing Devanagari.
A practical model could be:
Devanagari for widespread contemporary communication + Namey Dogra Akhar for cultural preservation and revival.
This allows linguistic heritage to be protected without creating unnecessary barriers to literacy or administration.
Language and the Indian Constitution
The Dogri example also helps clarify India's constitutional language framework.
The Eighth Schedule currently contains 22 languages, but inclusion does not simply mean that every scheduled language becomes an “official language of India” for all Union purposes.
Under Article 343, the official language of the Union is Hindi in Devanagari script, while English continues to be used for Union official purposes under the statutory framework.
The Eighth Schedule has a different constitutional role, including relevance to the composition of the Official Language Commission under Article 344 and the development of Hindi under Article 351.
States and Union Territories can have their own official-language arrangements.
In Jammu and Kashmir, Parliament enacted the Jammu and Kashmir Official Languages Act, 2020, under which Kashmiri, Dogri, Urdu, Hindi and English are official languages for specified official purposes.
This illustrates India's broader constitutional approach: national integration does not require linguistic uniformity.
The constitutional framework accommodates multiple languages while allowing practical arrangements for administration and communication.
