The Government's response has shifted from case-by-case police action (which is reactive and slow) to network-level pre-emption by the telecom regulator. The constitutional and legal backdrop is important: "Police" and "Public Order" are State subjects under Entry 1 and Entry 2 of List II (State List) of the Seventh Schedule. Cybercrime is allocated to the Ministry of Home Affairs (MHA) under the Government of India (Allocation of Business) Rules, 1961. DoT's tools operate in the telecom space — they disconnect misused connections — and share intelligence with I4C (MHA) rather than prosecuting crimes directly. Who governs what: DoT controls telecom infrastructure; MHA handles cybercrime investigation; State Police agencies prosecute offenders. The gap being filled: Even if police investigate a fraud after the fact, the mobile connection used is often deactivated or ported. ASTR and Chakshu act upstream — disconnecting misused SIMs before or during active fraud cycles. Legal basis: The Telecom Act, 2023 and the subscriber verification framework give DoT power to direct telecom service providers (TSPs) to disconnect non-compliant connections. ▤ Scheme at a Glance — Key Mechanisms ASTR (AI & Big Data Analytics Tool): Developed by DoT; identifies suspicious mobile connections using artificial intelligence and big-data analytics — cross-referencing subscriber data, biometric records, and usage patterns. Reverification trigger: Flagged connections are sent for reverification by TSPs; those that fail reverification are disconnected. Disconnections via ASTR (as on 15 Jul 2026): Over 88 lakh mobile connections disconnected after failing reverification. Sanchar Saathi — Chakshu facility: A citizen-facing portal where users report suspected fraud communications (calls, SMS, WhatsApp). DoT uses the crowd-sourced data in aggregate — not acting on individual complaints — to identify misuse patterns. Disconnections via Sanchar Saathi (as on 15 Jul 2026): Based on 11.18 lakh citizen reports, 50.90 lakh mobile connections have been disconnected. Digital Intelligence Platform (DIP): A bi-directional data-sharing hub between DoT, TSPs, I4C (MHA), SEBI-regulated entities, and other stakeholders — enabling real-time intelligence exchange on misuse of telecom resources for cyber-crimes and financial frauds. SEBI integration: SEBI has issued advisories to its regulated entities to onboard DIP; DoT has conducted dedicated sessions — more than 50 SEBI-regulated entities now on-boarded. Nodal ministry: Department of Telecommunications (DoT), Ministry of Communications. Partner agency (cybercrime): Indian Cyber Crime Coordination Centre (I4C), MHA.

Key Institutions & Terms to Know I4C (Indian Cyber Crime Coordination Centre): Apex body under MHA for coordinating cyber crime response across agencies and State police forces. Established in 2018, operationalised 2020. Sanchar Saathi: DoT's multi-purpose citizen portal — also handles CEIR (stolen phone blocking), TAFCOP (checking SIMs on one's ID), and Chakshu (fraud reporting). DIP (Digital Intelligence Platform): A secure, inter-agency intelligence hub — allows banks, SEBI entities, TSPs, and law enforcement to flag and cross-check data on misused telecom resources in near real-time. ASTR: Artificial Intelligence and Facial Recognition powered Telecom Sim Subscriber verification — uses AI to detect fake/fraudulent subscriber identities at scale. Seventh Schedule — List II: "Police" and "Public Order" are State List subjects, which is why DoT (a Central body) cannot prosecute cyber criminals — it can only manage the telecom layer and share intelligence with States and MHA. Telecom Act, 2023: Replaced the Indian Telegraph Act, 1885; gives DoT statutory backing for subscriber verification and disconnection orders. Critical View & Implementation Concerns Downstream accountability gap: DoT disconnects SIMs but SEBI-regulated entities and banks must separately pursue financial recovery; no single-window victim redress yet exists. SIM swapping and OTP fraud: Fraudsters are increasingly using legitimate-looking KYC documents via agents; AI-based tools like ASTR face adversarial adaptation as criminals improve document forgery. Jurisdictional fragmentation: With Police as a State subject, inter-State cybercrime requires coordination across multiple State CIDs, the CBI, and I4C — a multi-agency challenge that DIP partially addresses but doesn't fully resolve. SEBI-DoT integration is new: 50+ entities onboarded is a start, but SEBI has over 100 registered entities (brokers, depositories, AMCs) — full saturation is yet to be achieved. Crowd-sourced data reliability: Chakshu depends on citizen vigilance; false positives (legitimate numbers reported as fraudulent) could result in wrongful disconnections without a robust appeal mechanism. ✎ Mains Practice Question The Department of Telecommunications has developed tools such as ASTR and the Digital Intelligence Platform to combat cyber fraud. In light of the constitutional division of cybercrime jurisdiction between the Centre and States, critically examine the efficacy and limitations of a telecom-centric approach to cybersecurity governance in India. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 02 India's First Indigenous 350 kg-Thrust Expendable Turbo Jet Engine Successfully Developed by DRDO's GTRE GS-III · S&T — Defence Technology, IndigenisationPrelims + MainsPIB · DRDO · Ministry of Defence · 22 Jul 2026 DRDO's Gas Turbine Research Establishment has delivered India's first domestically designed expendable turbo jet engine of the 350 kg-thrust class — a milestone in a technology domain mastered by only a handful of nations worldwide. ◈ Background & Context Jet engine technology is among the most demanding engineering disciplines globally — requiring advanced metallurgy, ultra-precision manufacturing, and materials that withstand extreme temperatures and stresses. For decades, India relied on imported engines for its cruise missiles and unmanned platforms, limiting strategic autonomy. The Gas Turbine Research Establishment (GTRE), a DRDO lab in Bengaluru, has been India's primary centre for gas turbine development. It is also known for the Kaveri engine programme — a more powerful engine for fighter aircraft. The new turbo jet engine is in a different class: expendable (used once, in missiles or loitering munitions) and compact, at the 350 kg-thrust rating. Strategic context: Expendable turbo jets power single-use platforms such as cruise missiles, target drones, and loitering munitions — a fast-growing category in modern warfare. Make-in-India for defence: The engine was manufactured and assembled by Azad Engineering, Hyderabad, a private sector aerospace company identified by GTRE as the industry partner. Delivery date: Engine realised and delivered on 22 July 2026. ▤ Technical & Institutional Facts at a Glance Engine class: Expendable Turbo Jet — designed for single-use aerospace platforms (cruise missiles, target drones, loitering munitions). Thrust rating: 350 kg (approximately 3.43 kN). Designer: Gas Turbine Research Establishment (GTRE), DRDO, Bengaluru. Manufacturer: Azad Engineering, Hyderabad (private sector industry partner). Programme head (recipient): Dr K Rajalakshmi Menon, Distinguished Scientist & Director General (Aeronautical Systems), DRDO. GTRE Director: Dr SV Ramanamurty, Outstanding Scientist. DRDO Chairman: Shri Rajesh Kumar Singh, Defence Secretary & Secretary, Dept. of Defence R&D. Nodal ministry: Ministry of Defence. Significance: Nations with indigenous jet engine capability (of all classes): USA, UK, France, Russia, China, and now India in the expendable class. Why It Matters — Strategic & Industrial Significance Reduced import dependence: India has historically imported turbo jets from countries like Ukraine, France, and Russia for missiles and drones. Indigenous capability reduces this vulnerability — critical given recent global supply chain disruptions. Nirbhay & BrahMos lineage: India's Nirbhay cruise missile uses an imported turbo fan engine; this new GTRE engine could provide a domestic alternative for future variants. BrahMos uses a ramjet — a different type, but the indigenisation push covers that programme separately. Make-in-India for Defence: The GTRE–Azad Engineering partnership is a model for the government's defence PSU + private industry co-production policy, also exemplified by the LCA Tejas supply chain. Dual-use potential: Turbo jet technology in the expendable class has potential applications in target drones (used for training anti-aircraft gunners) and unmanned combat aerial vehicles (UCAVs). iDEX & DRDO tech transfer ecosystem: This fits the broader framework where DRDO designs and private industry manufactures — the model being pushed across missile, radar, and propulsion subsystems. Key Terms to Know (Prelims Hooks) Expendable engine: A jet engine designed for one-time use — lighter and cheaper than reusable engines; used in missiles and target drones that are not recovered. Turbo jet vs Turbo fan: A turbo jet passes all air through the combustion core (faster, less fuel-efficient); a turbo fan bypasses some air around the core (quieter, more fuel-efficient). Expendable missiles often use turbo jets for compactness. GTRE: Gas Turbine Research Establishment — DRDO lab responsible for gas turbine development since 1959. Best known internationally for the Kaveri engine programme (GTX-35VS). Azad Engineering: A Hyderabad-based precision aerospace company; supplies components to Safran, GE Aviation, Rolls-Royce, and Boeing — and now a manufacturer for DRDO's propulsion programme. Thrust class — 350 kg: This is a lightweight engine; for comparison, the Kaveri targets ~80 kN (about 8,160 kg) for the LCA Tejas. The 350 kg engine is designed for small, fast platforms. Figure 2 — India's First Indigenous Expendable Turbo Jet Engine (350 kg thrust class) The GTRE-designed, Azad Engineering-manufactured expendable turbo jet engine — compact, precision-machined, and rated at 350 kg thrust. The multi-blade compressor fan (front) draws air into the combustion chamber; the cylindrical casing houses the turbine stages. Image: DRDO/PIB, 22 Jul 2026; reproduced with credit for educational use. ✎ Mains Practice Question India's indigenous jet engine development has long been considered a strategic deficit. In light of the successful development of the GTRE expendable turbo jet engine, analyse the significance of domestic propulsion technology for India's defence self-reliance and evaluate the challenges that remain in achieving full indigenous capability in advanced aircraft engine design. 15 marks · 250 words 03 India's Space Launch Programme: 12 Missions in 3 Years, Four Operational Launch Vehicles, and the Road to a ₹44 Billion Space Economy GS-III · S&T — Space Technology, Indigenisation, Space EconomyPrelims + MainsPIB · Department of Space · ISRO · Rajya Sabha Written Reply · 23 Jul 2026 A Parliament question has produced a comprehensive data-rich summary of India's space launch performance from July 2023 to June 2026 — 12 launch vehicle missions, four operational launch vehicles, a landmark 100th launch from Sriharikota, and an ambitious target to grow India's space economy to USD 44 billion by 2033. ◈ Background & Context India's space programme, managed by the Department of Space (under the PMO) and executed primarily by ISRO, has undergone significant structural changes since 2020. The establishment of IN-SPACe (Indian National Space Promotion and Authorisation Centre) and NewSpace India Limited (NSIL) as a commercial arm has opened the sector to private Non-Government Entities (NGEs). The period 2023–26 has been India's most productive space phase — marked by first-ever achievements on the Moon, the Sun, and in orbital docking. The data presented to Parliament provides a consolidated view of launch infrastructure, achievements, and next-generation development plans. Oversight structure: Department of Space → ISRO (research & development; launch operations) + IN-SPACe (authorisation & promotion) + NSIL (commercial launch services). Launch site: Satish Dhawan Space Centre (SDSC SHAR), Sriharikota, Andhra Pradesh — India's primary spaceport with two operational launch pads. Period covered in data: July 2023 to June 2026 (3 years). ▤ Key Data at a Glance — 3-Year Launch Record Total launch vehicle missions: 12 (July 2023 – June 2026) National satellites launched: 11 International customer satellites launched: 9 Operational launch vehicles: 4 — PSLV, GSLV, GSLV Mk III (LVM3), SSLV Space economy target: USD 44 billion by 2033 (government projection, per IN-SPACe roadmap) NSIL revenue: Available in audited financials; NSIL is the commercial launch services arm monetising ISRO's capabilities. Launch infrastructure being added: Third Launch Pad at Sriharikota (for NGLV & as standby for 2nd pad) + SSLV Launch Complex at Kulasekarapattinam, Tamil Nadu. Figure 2 — India's Space Milestones, July 2023 – June 2026 Jul 202320242025Jun 2026Chandrayaan-31st south-pole landingAditya-L1India's solar observatory100th LaunchSriharikota milestoneSPADEXIndia 4th to dock in spaceNISAR on GSLVNASA–ISRO SAR missionCMS-03 (LVM3)Heaviest sat to GTO Key milestones in India's space programme, Jul 2023–Jun 2026 — Chandrayaan-3, Aditya-L1, SPADEX, NISAR, and landmark satellite launches. The 7 Landmark Milestones — What Each Means Chandrayaan-3 (Aug 2023): India became the first country to soft-land near the south pole of the Moon — a scientifically crucial region suspected to harbour water-ice. The lander-rover (Vikram-Pragyan) operated for one lunar day (~14 Earth days). Aditya-L1 (Sep 2023, PSLV-C57): India's first dedicated solar observatory, positioned in a halo orbit around the Sun-Earth Lagrange Point 1 (L1) — approximately 1.5 million km from Earth. Carries 7 payloads studying the solar corona, solar wind, and magnetic fields. 100th Launch from Sriharikota: Achieved during this 3-year window — a landmark for India's spaceport, marking decades of cumulative launch activity since SHAR's first launch in 1971. SPADEX (Space Docking Experiment): India demonstrated orbital docking/undocking — becoming only the 4th country globally to do so (after USA, Russia, China). Docking is essential for future crewed missions, space stations, and satellite servicing. SSLV Development Completed: The Small Satellite Launch Vehicle completed its 3rd developmental flight; technology transfer agreement signed with Indian industry — making SSLV commercially available. NISAR Mission (on GSLV): The first joint NASA-ISRO mission — a Synthetic Aperture Radar satellite co-developed by both agencies. Launched on India's GSLV, marking a new level of technological partnership. CMS-03 / LVM3 (heaviest satellite): India launched its heaviest satellite to Geostationary Transfer Orbit (GTO) via the LVM3 — and in a subsequent LVM3 launch, placed the heaviest satellite ever from Indian soil for a US commercial customer. Launch Infrastructure — Present and Planned First Launch Pad (FLP), Sriharikota: Operational — used primarily for PSLV. Second Launch Pad (SLP), Sriharikota: Operational — used for GSLV, LVM3. Third Launch Pad (TLP), Sriharikota: Approved and under development — for Next Generation Launch Vehicle (NGLV); also serves as standby for SLP. SSLV Launch Complex (SLC), Kulasekarapattinam, Tamil Nadu: India's second launch site; specifically for SSLV launches and private/NGE launches. Kulasekarapattinam's near-equatorial location (9.08°N) advantages small satellite launches into low-inclination orbits. Next-Generation Technology Development Semi-cryogenic engine (200t thrust): Under development — will use liquid oxygen (LOX) and kerosene (more storable than liquid hydrogen), improving performance and storability vs. the current cryogenic stage. Semi-cryogenic booster for LVM3: Will substantially enhance LVM3's payload capacity to GTO. Vertical Take-off & Vertical Landing (VTVL): Reusability demonstration for the core stage — India's answer to SpaceX's Falcon 9 booster recovery model. LOX-Methane engine: High thrust; methane is considered the propellant of the future for deep-space missions (SpaceX Starship, Rocket Lab also use methane). NGLV (Next Generation Launch Vehicle): A partially reusable rocket with LOX-Methane propulsion — India's planned successor to LVM3 for heavy payloads. ORV (Orbital Re-entry Vehicle) / Winged Body: A reusable orbital vehicle that launches on an ascent vehicle and lands on a runway — analogous to the Space Shuttle's concept, though smaller. Air-breathing propulsion: Uses atmospheric oxygen rather than onboard oxidiser — massively reduces launch mass. ISRO has been testing Scramjet technology since 2016. IN-SPACe Policy Ecosystem & Private Sector NGE access to ISRO facilities: Private entities may now establish temporary test facilities within ISRO premises — reducing time and cost for private launch system development. Financial support: IN-SPACe offers grants and incentives for startups and MSMEs in the space sector. Space manufacturing clusters: Policy to build a domestic supply chain for space hardware — similar to the defence corridor model. NSIL (NewSpace India Limited): A Government of India company under the Department of Space — acts as the commercial arm, offering launch services (PSLV, GSLV, LVM3) to foreign and domestic customers, and managing demand aggregation for satellite communication. Space Economy Target: IN-SPACe roadmap projects India's space economy at USD 44 billion by 2033 — compared to an estimated ~USD 8 billion in 2023 (approximately 2–3% of global space economy). This is a government projection, not an achieved figure. ✎ Mains Practice Question India's space programme has transitioned from a purely scientific endeavour to a strategic and commercial enterprise. Critically evaluate the role of institutions such as IN-SPACe and NSIL in enabling private sector participation, and assess whether India's target of a USD 44 billion space economy by 2033 is achievable given current infrastructure and policy trajectories. 15 marks · 250 words 04 Aditya-L1 and Chandrayaan-3: Scientific Findings and Their Significance for India's Future Space Programme GS-III · S&T — Space Science, Planetary ExplorationPrelims + MainsPIB · Department of Space · ISRO · Rajya Sabha Written Reply · 23 Jul 2026 Parliament has received a detailed science report on the findings of Aditya-L1 and Chandrayaan-3 — results that have been published in peer-reviewed international journals and are actively shaping India's roadmap for Venus, Chandrayaan-4, and long-term deep space exploration. ◈ Background & Context Aditya-L1 (launched September 2023) and Chandrayaan-3 (landed August 2023) are India's two most scientifically productive missions in recent years. Both have now yielded published results — moving India from a status of primarily achieving engineering milestones to becoming a producer of primary, high-impact space science data. Note that Aditya-L1 is a solar physics mission, not a space weather prediction mission — this distinction matters for answers. However, its data contributes to understanding solar behaviour, which indirectly informs space weather research. The government explicitly clarified this in the Parliamentary reply. Aditya-L1 orbit: Halo orbit around the Sun-Earth L1 Lagrange point (~1.5 million km from Earth) — provides uninterrupted view of the Sun without eclipses. Chandrayaan-3 landing site: Named "Shiv Shakti Point", near the lunar south pole — the first mission to successfully operate at high lunar latitudes. Aditya-L1 — Key Scientific Achievements First-ever CME onset spectroscopy: Aditya-L1 captured the first-ever spectroscopic signatures of the onset phase of a Coronal Mass Ejection (CME) — the moment when a massive chunk of solar plasma begins to eject. CMEs are the primary driver of geomagnetic storms that can disrupt power grids, GPS, and communications on Earth. Geomagnetic storm analysis (May & Oct 2024): By combining Aditya-L1's direct particles-and-fields observations with ground-based magnetometer data, scientists explained some of the most intense geomagnetic storms of 2024 — the strongest in two decades. Iron fluorescence on the Sun: First comprehensive analysis of photospheric iron fluorescence — recorded across 47 massive X-class solar flares during the peak of Solar Cycle 25 (2024). X-class flares are the most powerful category of solar flares. Near-UV solar flare observations: Unprecedented high-resolution details of powerful solar flares in near-ultraviolet (NUV) wavelengths, capturing the first highly detailed view of a rare solar plasma ejection in ultraviolet light. Space weather implications: Experience from Aditya-L1 is building India's foundational capability for eventual space weather prediction — critical for protecting satellites, power infrastructure, and astronaut safety. Chandrayaan-3 — Key Scientific Findings at Shiv Shakti Point Only successful polar lander: Chandrayaan-3 remains the only mission to have successfully operated at the lunar polar region — all previous polar attempts (including Russia's Luna-25 in 2023) failed. ChaSTE thermal probe — subsurface temperature profile: The probe penetrated 10 cm deep, recording the first-ever in-situ high-latitude temperature profile. Key findings: Massive vertical temperature gradient during lunar morning. Sub-zero temperatures below 8 cm depth. A distinct two-layer "cake-like" regolith structure at ~6 cm — a sharp change in thermal conductivity and diffusivity. Water-ice insulation implication: The top 2–6 cm of lunar regolith is hyper-porous but highly cohesive — acting as an effective thermal blanket that insulates potential subsurface water-ice molecules from the extreme temperature swings of the lunar surface. APXS elemental composition: The Alpha Particle X-ray Spectrometer on the Pragyan rover found a highly uniform elemental composition within 50 metres of the landing site, with elevated abundances of magnesium-rich minerals. This supports the Lunar Magma Ocean (LMO) hypothesis and suggests deep mantle materials were ejected during the formation of the nearby South Pole-Aitken (SPA) Basin — the largest and oldest impact basin on the Moon. RAMBHA-LP Langmuir probe — near-surface plasma: First-ever high-latitude near-surface plasma measurements on the Moon. Recorded electron densities of 300–650 electrons/cm³ and elevated kinetic temperatures of 3,000–8,000 K — confirming that near-surface plasma is energetic, non-thermal, and heavily influenced by solar wind and Earth's geomagnetic tail. ILSA seismometer — lunar seismic activity: Recorded over 250 distinct vibration events at Shiv Shakti Point. ~200 correlated to rover/instrument operations; the remaining provide data on local lunar seismic activity — a first for the polar region. Figure 3 — The Five Lagrange Points of the Sun-Earth System L1 (~1.5 million km sunward of Earth) is where Aditya-L1 orbits in a halo — giving it an uninterrupted view of the Sun. L2 (~1.5 million km anti-sunward) hosts JWST. L3, L4, L5 are the remaining gravitational balance points; L4 and L5 are stable (host the Trojan asteroids of Jupiter). Image: Wikimedia Commons (public domain); reproduced for educational use. Feeding Into Future Missions Venus Orbiter Mission: Deep-space navigation, halo orbit maintenance, and autonomous payload operations from Aditya-L1 are directly informing trajectory planning and thermal management for the Venus mission. Chandrayaan-4 (sample return): High-precision landing, sensor fusion, and autonomous hazard avoidance algorithms from Ch-3 are the baseline for sample return mission guidance systems. Chandrayaan-4 aims to collect and return lunar samples to Earth. Chandrayaan-5/LuPEX (Lunar Polar Exploration): Joint mission with JAXA (Japan) for deeper exploration of the lunar south pole — building on Ch-3's thermal and regolith findings. Key Terms for Prelims CME (Coronal Mass Ejection): A large cloud of magnetised plasma ejected from the Sun's corona — can cause intense geomagnetic storms when directed at Earth. X-class solar flare: The most powerful category of solar flare; can disrupt radio communications, damage satellites, and trigger aurora at low latitudes. Lagrange Point L1: A gravitational balance point between the Sun and Earth where a spacecraft can maintain a stable orbit — ~1.5 million km from Earth, allowing continuous solar observation. South Pole-Aitken (SPA) Basin: One of the largest known impact craters in the Solar System (~2,500 km diameter, up to 8 km deep) — located at the lunar south pole. Believed to contain ancient mantle material and water-ice. LMO (Lunar Magma Ocean) Hypothesis: The theory that the Moon was once entirely covered by a molten magma ocean, which gradually cooled and differentiated — explaining the different rock types seen across the lunar surface. Regolith: The layer of loose, unconsolidated rock and dust on the surface of the Moon (and other planetary bodies) — analogous to soil on Earth but formed entirely by meteorite impacts and solar wind. ChaSTE: Chandra's Surface Thermophysical Experiment — the thermal probe on Chandrayaan-3's Vikram lander. APXS: Alpha Particle X-ray Spectrometer — mounted on the Pragyan rover; determines elemental composition of soil/rocks by bombarding them with alpha particles. ILSA: Instrument for Lunar Seismic Activity — a seismometer on the Vikram lander. RAMBHA-LP: Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere — Langmuir Probe; measures near-surface plasma properties. NISAR: NASA-ISRO Synthetic Aperture Radar — jointly developed Earth observation satellite using L-band and S-band SAR to monitor land deformation, ice sheets, wetlands, and disaster impacts. SPADEX: Space Docking Experiment — ISRO's mission that demonstrated autonomous orbital rendezvous and docking, making India the 4th country to master this technology. ✎ Mains Practice Question The scientific outcomes of the Chandrayaan-3 mission have provided data that no previous mission — including Apollo and Luna — was able to collect from the lunar polar region. Discuss the significance of these findings in the context of future lunar exploration, water-ice prospecting, and India's long-term space programme roadmap. 15 mar

Editorials, Opinions & Explained2 Items Core TopicImportantConcise EditorialsEditorial Page 01Index of Core Industries — New Series02Corruption — Institutions, RTI, and Rule of Law EditorialsEditorial Page 01 Core Upgrade: The Revised Index of Core Industries and What It Signals Core TopicEditorialGS-III · Economy — Growth, Development & Infrastructure; Index NumbersPrelims + MainsThe Hindu · Editorial The long-overdue revision of the Index of Core Industries (ICI) — incorporating an updated base year, a ninth sector, and recalibrated weights — offers both a sharper economic barometer and an opportunity to reflect on persistent structural gaps in India's statistical architecture. ◈ Background & Context The ICI measures output across sectors considered foundational to industrial activity. Like the IIP, WPI, CPI, and national accounts — all updated earlier in 2025–26 — the ICI had operated on an outdated base year, creating a representational lag between measured activity and the actual economy. The revised series updates the base year and introduces iron ore as a ninth sector, joining the existing eight: coal, crude oil, natural gas, refinery products, fertilisers, steel, cement, and electricity. Methodological corrections address double-counting in the steel and coal sectors. The ICI carries significant weight in the Index of Industrial Production (IIP), making its accuracy important for broader macroeconomic assessments. Revised Weights: What Has Changed and Why It Matters The redistribution of sectoral weights reflects shifts in the actual structure of the Indian economy. The changes are not merely technical — they carry interpretive significance for how India's industrial trajectory is understood. Coal and natural gas have seen their weights nearly halved, to approximately 5.6% and 3.8% respectively — consistent with their declining relative share in primary energy demand. Electricity now constitutes over 30% of the index, up from less than 20% in the old series, reflecting surging power demand and the expanding role of renewable generation. The inclusion of iron ore corrects a significant omission given the sector's role in steel production and export earnings. Figure 1 — Indicative Shift in Sectoral Weights: ICI Old vs. New Series 0%10%20%30%10.3%5.6%Coal6.9%3.8%Natural Gas~20%>30%ElectricityOld SeriesNew Series The electricity sector's weight more than doubled in the revised ICI, reflecting the surge in power demand and renewables capacity; coal and natural gas weights have contracted markedly. June 2026 ICI Performance and the Base Effect Caveat The inaugural data release under the new series showed ICI growth of 5% in June 2026 — a five-month high — suggesting that industrial output may be recovering from the demand disruption caused by the West Asia crisis. However, the headline figure warrants careful interpretation. Iron ore grew by 43.9% and electricity by 9.8%, but both sectors had contracted in June 2025, creating a favourable statistical base effect that artificially inflates year-on-year growth. Whether this momentum is sustained will become clearer over the next two to three months as the base effect dissipates. The crude oil and natural gas sectors continued to contract — for 18 and 24 consecutive months, respectively — pointing to deep-seated supply-side constraints in upstream hydrocarbon extraction. ▤ Key Data Points ICI growth in June 2026: 5% (five-month high under new series) Iron ore growth: 43.9% (base-effect driven) Electricity growth: 9.8% (base-effect driven) Crude oil contraction: 18 consecutive months Natural gas contraction: 24 consecutive months Electricity's new ICI weight: >30% (vs. <20% earlier) The Statistical Governance Dimension Beyond the data itself, the editorial raises a structural administrative question: whether the WPI and ICI, currently administered by the Ministry of Commerce and Industry, should be transferred to the Ministry of Statistics and Programme Implementation (MoSPI), which already handles the CPI and IIP. Consolidating major price and production indices under MoSPI would enhance methodological coherence, reduce inter-ministerial statistical inconsistencies, and improve transparency. The concurrent revision of the WPI and ICI was a natural window for such a reorganisation — a window that has not yet been acted upon but remains open. India's statistical system has historically suffered from delayed base-year revisions and fragmented administrative ownership — both of which affect the credibility and usability of official data. ✎ Mains Practice Question The recent revision of the Index of Core Industries raises questions about the design and governance of India's official statistical architecture. Critically examine the significance of base-year updates, sectoral reweighting, and administrative consolidation for the quality and credibility of economic data in India. 15 marks · 250 words 02 Corruption as a Systemic Failure: Institutions, Accountability, and the Rule of Law Core TopicEditorialGS-II · Governance — Transparency, Accountability, Statutory Bodies, RTIGS-IV · Ethics — Public Service Values, IntegrityPrelims + MainsThe Hindu · Opinion Corruption in India persists not merely as a behavioural failing but as a systemic outcome of weakened accountability institutions, diluted transparency legislation, and a judicial framework that renders enforcement negligible — making it, structurally, a near risk-free activity. ◈ Background & Context The NEET-UG paper leak of 2024 reignited public debate on institutional accountability, evoking comparisons with the India Against Corruption movement of 2011–12. The editorial, structured as a moderated dialogue between a former Central Information Commissioner and a transparency activist, diagnoses corruption as a governance failure rather than an individual moral lapse. India files approximately six million RTI applications annually — the highest volume in the world — demonstrating high demand for institutional accountability. Major scams — Vyapam, Adarsh Housing Society, the electoral bond scheme — were exposed in part through RTI applications, demonstrating the Act's investigative utility. India ranked 79th in the Rule of Law Index (cited in the editorial), indicating significant deficits in legal enforcement capacity. Digitalisation: Promise vs. Ground Reality While digitalisation of government services was promoted as a structural solution to petty corruption by eliminating human intermediaries, its effects on corruption have been more ambiguous in practice. Digitalisation has not eliminated the expectation of bribes within government offices; informal payment norms continue in many service-delivery contexts. For the poor and digitally excluded, online service delivery has introduced new intermediaries — private internet cafes charging excessive fees — effectively displacing rather than removing the corruption node. The absence of a statutory grievance redressal mechanism — a Bill discussed in Parliament as early as 2014 but not enacted — means complainants have no legally enforceable remedy or timeline. The RTI Act: Legislative Erosion and Judicial Dilution The Right to Information Act, 2005, is assessed in the editorial as one of the most robust transparency statutes in the world at the time of enactment. Its effectiveness has since been eroded through a combination of judicial interpretation and legislative amendment. The Girish Ramchandra Deshpande judgment of the Supreme Court broadly interpreted the personal information exemption, allowing a wide range of disclosures to be denied to citizens on privacy grounds. The Puttaswamy judgment (2017), while recognising privacy as a fundamental right, did not establish a proportionality or balancing framework between the right to information and the right to privacy — weakening RTI in practice. The Digital Personal Data Protection (DPDP) Act, 2023, has amended the RTI Act in ways that allow information relating to corruption to be withheld under the personal data rubric, a development described as effectively dismantling the Act's accountability function. Section 17A of the Prevention of Corruption Act (introduced 2018) requires prior government sanction before a corruption investigation can even be initiated — a procedural barrier that substantially insulates serving officials. Figure 2 — Institutional Mechanisms Weakening RTI-Based Accountability RTI Act 2005Strong transparencyframeworkJudicial DilutionDeshpande judgment:broad personal-info barPuttaswamy: no balanceLegislative AmendmentDPDP Act 2023:corruption info may bewithheld as 'personal data'Accountability GapMajor corruption casesshielded; institutionsfunctionally compromised A sequence of judicial interpretations and the DPDP Act 2023 has progressively narrowed the RTI Act's scope, creating structural shields against transparency-based accountability. Institutional Capture: CBI, ED, Lokpal, and Information Commissions The editorial identifies a pattern of selective enforcement by anti-corruption institutions, with accountability mechanisms functioning vigorously against political opponents while systemic impunity persists for those in power. The Lokpal, established after sustained public agitation, is described as incurring significant annual expenditure while delivering negligible accountability outcomes. Lokayuktas at the state level have similarly failed to demonstrate deterrent effect against systemic corruption despite decades of existence. The CBI's anti-corruption branch historically showed strong conviction rates (144 of 280 accused, 1980–84), but average time to first trial was 88 months — rendering even successful prosecutions largely non-deterrent, with only four individuals imprisoned for more than 20 days in an 18-year study period. Information Commissioner appointments have been consistently delayed and conducted without transparency — undermining the very independence required for RTI oversight. The Way Forward: Structural Reforms Required Judicial reform: A roadmap to resolve over 90% of corruption cases within one year, as practised in several comparable democracies. RTI restoration: Reversal of the DPDP Act's amendments to the RTI Act; transparent, statutory criteria for Information Commissioner appointments. Grievance redressal legislation: Enactment of a time-bound grievance redressal law to create enforceable remedies for corruption at the service-delivery level. Enforcement independence: Institutional reforms to insulate the CBI, ED, and Lokpal from political direction, with mandatory public reporting on case progression. Media accountability: Sustained public tracking of high-profile corruption cases to maintain pressure beyond the initial news cycle. ▤ Key Statutory & Institutional References RTI Act, 2005 — Section 8 (exemptions, including personal information) Prevention of Corruption Act — Section 17A (sanction required for investigation, introduced 2018) DPDP Act, 2023 — amendments narrowing RTI disclosure obligations Lokpal and Lokayuktas Act, 2013 — national anti-corruption ombudsman Girish Ramchandra Deshpande vs. CIC (2013) — SC on personal information exemption K.S. Puttaswamy vs. Union of India (2017) — SC recognising right to privacy as fundamental right ✎ Mains Practice Question "Corruption in India is not merely a moral failure but a structural outcome of weakened accountability institutions and diluted transparency legislation." In light of this, evaluate the effectiveness of the RTI Act, Lokpal, and the Prevention of Corruption Act in combating corruption, and suggest institutional reforms needed. 15 marks · 250 words

The Street Vendors Act, 2014, was enacted to end arbitrary evictions by laying down a step-by-step regulatory process — it neither prohibits vending on public streets nor grants vendors unrestricted rights over public spaces. Street vending has been held by the Supreme Court to be a legitimate occupation protected under Article 19(1)(g) of the Constitution, subject to reasonable regulation in the public interest. Bengaluru's drive proceeded without constituting a Town Vending Committee (TVC) — the statutory precondition for all regulatory action under the Act. Mandatory Procedure Under the Act Step 1 — TVC Constitution: Every city must form a Town Vending Committee comprising officials, police, planning authorities, resident representatives, and street vendors (minimum 40% of members), with representation for women and marginalised communities. Step 2 — Survey of existing vendors: The TVC must survey all vendors currently operating before any decision on who can vend and where. Step 3 — Certificates of Vending: Eligible vendors are issued certificates specifying location and conditions. The Act expressly bars eviction or relocation until the survey is complete and certificates issued. Step 4 — Zoning: The TVC identifies vending zones and no-vending zones. Bengaluru currently has neither a TVC nor declared zones. ✎ Mains Practice Question The Street Vendors (Protection of Livelihood and Regulation of Street Vending) Act, 2014, attempts to balance two competing constitutional rights. In light of the tensions exposed by Bengaluru's 'Safe Footpath' drive, critically examine the Act's procedural framework and the challenges in its implementation. 15 marks · 250 words 02 Right to Protest and the Limits of Police Power: Constitutional and Legal Framework GS-II · Polity — Fundamental Rights, Judicial Review, Internal SecurityPrelims + MainsThe Hindu · Explainer The Cockroach Janta Party's 'Chalo Sansad' march at Jantar Mantar on July 20, demanding NTA reform, descended into police action involving tear gas and lathi charges — reigniting constitutional debate on the scope of the right to protest and the standards governing police force. ◈ Background & Context Article 19(1)(b) guarantees the right to assemble peacefully, subject to reasonable restrictions under Article 19(3) in the interests of public order and national integrity. Delhi Police cited prohibitory orders under Section 163 BNSS barring marches in the New Delhi district outside designated sites. Whether an assembly is "unlawful" under the Bharatiya Nyaya Sanhita (BNS) depends on whether its common object involves criminal force, resistance to law, or compulsion by threat — not merely the absence of permission. A lawful assembly may become unlawful if its conduct changes during the event — a fact-specific determination. The Delhi High Court has sought responses from the Centre and Delhi Police on petitions alleging police brutality and excessive use of force. Standards Governing Police Action The NHRC Manual on Human Rights for Police Officers states that force, when inevitable, must be the "irreducible minimum" required, consistent with UN Basic Principles on the Use of Force and Firearms (lawful, necessary, proportionate). Anita Thakur v. State of J&K (2016): Supreme Court held excessive force violates fundamental rights; awarded compensation to injured protesters. Mazdoor Kisan Shakti Sangathan v. UoI (2018): Authorities may regulate demonstrations for public order but cannot extinguish the right to protest entirely. Amit Sahni v. Commissioner of Police (2020) [Shaheen Bagh]: Dissent is a constitutional right, but indefinite occupation of public spaces is not protected. The BNSS requires police officers making arrests to carry visible identification, but has no corresponding rule for crowd-control personnel — a gap raised by the Jantar Mantar incident. ✎ Mains Practice Question Discuss the constitutional and statutory framework governing the right to protest in India. How have Supreme Court judgments attempted to balance the right to assemble peacefully with the state's obligation to maintain public order? Illustrate with relevant case law. 15 marks · 250 words 03 Fast-Track Courts in India: Legal Basis, Performance, and Structural Constraints GS-II · Governance — Judiciary, Justice Delivery, Judicial ReformsPrelims + MainsThe Indian Express Prime Minister Modi's announcement of fast-track courts to handle examination paper-leak cases has renewed scrutiny of what these courts can — and structurally cannot — achieve in India's justice delivery system. ◈ Background & Context There is no single central legislation governing fast-track courts (FTCs). The 14th Finance Commission (2015–20) recommended FTCs for heinous offences and cases involving vulnerable groups. In 2019, following amendments to criminal law and a Supreme Court directive, the Union government launched the Fast-Track Special Courts (FTSC) scheme, funded partly by the Nirbhaya Fund, specifically for rape cases and POCSO offences. As of January 2026: 862 regular FTCs functioning across 21 states/UTs; 774 FTSCs (including 398 exclusive POCSO courts) across 29 states/UTs. FTSCs dispose of approximately 9.5 cases per month, versus 3.3 by a regular trial court of comparable jurisdiction. Over 2.4 lakh cases remained pending in FTSCs by end-2023, illustrating that disposal rate and pendency are not the same metric. Constitutional and Legal Constraints Article 14 (equality before law) requires that cases assigned to special courts have a rational, objective basis — offence type or victim vulnerability — not merely the "object of speedier trial" (State of WB v. Anwar Ali Sarkar, 1952). The BNSS recommends (not mandates) trial completion within two years for general offences and two months for sexual offences — there is no statutory right to a fixed deadline. In P. Ramachandra Rao v. State of Karnataka (2002), a seven-judge Constitution Bench ruled it is "neither advisable nor judicially permissible" to prescribe a universal outer limit for criminal proceedings. ▤ Key Numbers FTSC target: 41–42 cases per quarter (≈165 annually) Disposal rate: ~96% (heard or dismissed, not necessarily adjudicated) Pendency in FTSCs (end-2023): >2.4 lakh cases RBI currency printing spend (last decade): ₹52,095 crore — cited for scale comparison ✎ Mains Practice Question Fast-track courts are often proposed as a solution to India's judicial pendency crisis. Critically examine the legal basis, performance record, and structural limitations of fast-track courts in India, and suggest measures to improve justice delivery. 15 marks · 250 words International RelationsGeneral Studies Paper II 04 India at the 21st East Asia Summit: Maritime Safety, Myanmar, and the Indus Waters Treaty GS-II · IR — India's Foreign Policy, Indo-Pacific, Multilateral ForumsPrelims + MainsThe Hindu External Affairs Minister S. Jaishankar, participating in the 21st East Asia Summit (EAS) in Manila, articulated India's position on global maritime safety, the South China Sea Code of Conduct, the Myanmar conflict, and India-Pakistan tensions — while the MEA sharply rebutted Pakistan's remarks at the ASEAN Regional Forum. ◈ Background & Context The East Asia Summit is a premier Indo-Pacific leaders' forum. India has been a member since 2005. The 21st EAS met against the backdrop of the ongoing West Asia/Gulf conflict and continued instability in Myanmar following the military coup of February 2021. On maritime safety: Jaishankar stated that global waterways "must remain safe and unimpeded" and that attacks on seafarers, civilian shipping, or infrastructure are unacceptable — consistent with India's concern about Houthi disruptions in the Red Sea. On South China Sea: India supports a "substantive, effective and legally binding Code of Conduct" fully compliant with UNCLOS 1982, without prejudicing the rights of all users. On Myanmar: India backed ASEAN efforts for a political solution; Myanmar's Ethnic Armed Organisations (EAOs) have been challenging the junta since the 2021 coup. India announced hosting the 7th EAS Maritime Security Cooperation Conference in Kochi and an EAS Maritime Heritage Festival in Lothal (ancient Harappan port city, Gujarat). India-Pakistan: IWT and ARF Pakistan Deputy PM Ishaq Dar used the ARF to call for resolution of the Kashmir dispute per UNSC resolutions and described the Indus Waters Treaty as a cornerstone of regional stability. The MEA spokesperson Randhir Jaiswal termed Pakistan's remarks a "cynical exploitation" of multilateral forums to "amplify falsehoods" and "peddle state-sponsored disinformation". India has previously placed the Indus Waters Treaty in abeyance following the Pahalgam attack — a development that has created diplomatic friction. ✎ Mains Practice Question Examine India's strategic interests in the East Asia Summit framework. How does India's position on maritime safety, South China Sea, and Myanmar reflect its broader Indo-Pacific foreign policy priorities? 10 marks · 150 words 05 US–Saudi Civilian Nuclear Agreement: Strategic Calculus, Non-Proliferation Concerns, and Regional Implications GS-II · IR — Nuclear Diplomacy, Gulf Security, Non-Proliferation RegimePrelims + MainsThe Hindu The United States and Saudi Arabia announced a landmark civilian nuclear cooperation agreement on July 23, 2026 — a development with far-reaching implications for Gulf security, the global non-proliferation regime, and the ongoing US-Iran conflict. ◈ Background & Context The deal was announced while the US is engaged in an armed confrontation with Iran — which began partly over concerns about Iran's nuclear programme — and remains a key point of contention in now-stalled peace negotiations. Saudi Arabia has long asserted its right to a civilian nuclear programme; last year it signed a mutual defence pact with nuclear-armed Pakistan. President Trump stated the deal is "totally subject" to Saudi Arabia joining the Abraham Accords (normalisation with Israel), linking strategic-economic interests to regional political realignment. Reports indicate the agreement may include a provision allowing US companies to build a uranium enrichment facility in Saudi Arabia — though Trump publicly denied this, and the Energy Department made no mention of it. US Secretary of State Marco Rubio stated any civilian nuclear agreement will include "safeguards to ensure it can't be turned into a weapons programme". Figure 1 — Saudi Arabia: Location and Regional Context Saudi Arabia borders Iraq, Kuwait, UAE, Oman, and Yemen, making it a pivotal player in Gulf security architecture. Image: BBC/public domain map; reproduced with credit for educational use. Non-Proliferation Concerns and Strategic Implications Proliferation risk: Policymakers have long argued that if Iran acquires a nuclear weapon, a regional arms race across the Gulf becomes probable. A Saudi enrichment capability would materially accelerate that risk. Bilateral comparison: The US maintains civilian nuclear cooperation agreements ('123 Agreements' under the Atomic Energy Act) with over 50 countries. Saudi Arabia's deal is contentious because enrichment rights are not standard in such agreements. Congressional review: The deal must be submitted to Congress. The Republican-controlled legislature is unlikely to block it, though lawmakers from both parties and Israeli officials have historically opposed Saudi enrichment capabilities. India's context: The India-US civilian nuclear deal (2008) — also a 123 Agreement — did not grant India enrichment or reprocessing rights in US-supplied facilities, setting a different precedent. ▤ Key Terms & Prelims Facts 123 Agreement: Named after Section 123 of the US Atomic Energy Act, 1954; required for any significant nuclear cooperation between the US and another country. Abraham Accords (2020): US-brokered normalisation agreements between Israel and UAE, Bahrain, Sudan, and Morocco — Saudi Arabia has not yet joined. NPT: Nuclear Non-Proliferation Treaty; Saudi Arabia is a signatory. Enrichment is permitted under NPT but must be under IAEA safeguards. IAEA Safeguards: Verification system to ensure nuclear material is not diverted from civilian to military use. ✎ Mains Practice Question The US–Saudi civilian nuclear agreement raises fundamental questions about the global non-proliferation regime. Critically examine the strategic rationale, safeguard mechanisms, and proliferation risks associated with civilian nuclear cooperation agreements in a volatile regional context. 15 marks · 250 words EconomyGeneral Studies Paper III 06 RBI's Polymer Currency Trial: Environmental, Security, and Import-Dependency Considerations GS-III · Economy — Monetary Policy, Currency Management, Environmental ImpactPrelims + MainsThe Indian Express A tender floated by Bharatiya Reserve Bank Note Mudran Pvt Ltd (BRBNMPL) for 3.4 crore polymer sheets signals the RBI's resumption of plastic banknote trials — approximately 15 years after a similar exercise was abandoned — reigniting debate on the merits and risks of replacing cotton-based currency with polymer notes. ◈ Background & Context Polymer banknotes were first issued by Australia in 1988 and are now used in over 50 countries, including the UK, Canada, New Zealand, Thailand, Vietnam, Malaysia, and Singapore. India's 2009–12 trial of ₹10 polymer notes across five climatically diverse cities (Kochi, Mysuru, Shimla, Jaipur, Bhubaneswar) was abandoned due to "technical infirmities". The RBI spent ₹52,095 crore over the last decade printing nearly 26,000 crore note pieces — accounting for 15–44% of its total expenditure (excluding provisions) in any given year. In the last three years, for every four new notes supplied, approximately three soiled notes were destroyed — a cycle polymer's greater durability would slow considerably. Figure 2 — RBI Currency Printing Costs & Volume (FY17–FY26) Printing costs peaked at ₹7,965 crore in FY17 due to demonetisation-driven volume; costs have since stabilised around ₹4,875–₹5,101 crore annually. Source: RBI; reproduced from The Indian Express for educational use. Key Advantages of Polymer Notes Durability: Polymer notes last two to six times longer than cotton-based notes, depending on denomination — lower-denomination notes circulate more intensively and degrade faster. Environmental benefit: A 2013 TERI study (commissioned by RBI) found significant environmental gains; polymer waste can be granulated and recycled into compost bins, plumbing fittings, and other products. Security: Most counterfeit notes globally are produced on paper. India detected 2.3 lakh counterfeit notes in 2025–26 (up from 2.17 lakh in 2024–25); polymer's resistance to counterfeiting could reduce this. Cost over lifecycle: Though one polymer note costs more to manufacture than a paper one, fewer notes need be produced and replaced, reducing overall lifecycle cost. Key Risks and Challenges Import dependency: The polymer substrate may need to be imported; the BRBNMPL tender required bidders to "firewall" operations in Pakistan or China from Indian operations — acknowledging supply-chain vulnerability in a security-sensitive domain. Sunk investment: Significant capital has been invested in existing cotton-paper note infrastructure. Bank Note Paper Mill India and BRBNMPL's Mysuru ink factory represent domestic capacity that any transition would have to account for. Gradual transition required: Any shift must be incremental, with parallel investment in polymer-compatible printing infrastructure. ✎ Mains Practice Question Discuss the environmental, security, and economic considerations involved in transitioning India's currency from cotton-based to polymer banknotes. What are the key challenges that must be addressed for a successful implementation? 10 marks · 150 words Science & TechnologyGeneral Studies Paper III 07 Beta Pictoris d: JWST Discovers a Third Directly-Imaged Exoplanet Using Atmospheric Spectroscopy GS-III · Science & Technology — Space Science, Exoplanet Detection, SpectroscopyPrelims + MainsDeccan Chronicle · AP Two independent teams — one Scottish-German using ESO's Very Large Telescope, another from UC San Diego using NASA's James Webb Space Telescope — have announced the discovery of Beta Pictoris d, the third directly imaged planet in the Beta Pictoris system and the faintest planet ever directly imaged from Earth. ◈ Background & Context Beta Pictoris is a young star system approximately 23 million years old, located 63 light-years from Earth in the southern constellation Pictor (the Painter/Easel). It hosts a prominent debris disk and has been a key target for studying planetary formation. The system previously hosted two known planets: Beta Pictoris b (one of the first directly imaged exoplanets) and Beta Pictoris c. With Beta Pictoris d, it becomes the second known planetary system with at least three directly imaged planets. Fewer than 100 of over 6,000 confirmed exoplanets have been detected through direct imaging; most are found via the transit method (dimming of starlight as the planet passes in front). Figure 3 — Direct Image of the Beta Pictoris System (ESO/VLT) The star symbol (★) marks Beta Pictoris; the bright object to the left is a known companion planet; the faint dot indicated by the arrow (↑) is the newly discovered Beta Pictoris d — approximately 100 times dimmer than the known companion. Image: ESO/VLT; reproduced for educational use. About Beta Pictoris d Mass: At least twice the mass of Jupiter, making it the smallest of the three known giant planets in the system. Orbit: Approximately 30 astronomical units (AU) — comparable to Neptune's distance from the Sun — and the widest orbit among the three planets. Takes 91 years to complete one revolution (similar to Uranus's orbital period). Had remained hidden within one of the brightest known debris disks, making conventional imaging difficult. Discovery Method: NIRSpec Spectroscopy (JWST) Discovered accidentally using JWST's Near-Infrared Spectrograph (NIRSpec) Integral Field Unit while studying Beta Pictoris b — the planet's chemical signature and motion were detected spectroscopically, not visually. Carbon monoxide (CO) absorption lines and radial velocity analysis confirmed its planetary nature. Follow-up using JWST's Mid-Infrared Instrument (MIRI) detected water vapour and methane in its atmosphere. This is the first directly-imaged exoplanet discovered primarily through moderate-resolution spectroscopy — demonstrating a new method: detecting hidden planets via atmospheric chemical fingerprints rather than visual brightness alone. The VLT-based Scottish-German team independently confirmed the discovery within days, having found it hidden in archival data going back 11 years. ▤ Key Instruments & Terms (Prelims) JWST: James Webb Space Telescope (NASA); largest space telescope ever launched; operates primarily in infrared. NIRSpec: Near-Infrared Spectrograph — one of JWST's four science instruments; can observe 100 objects simultaneously. MIRI: Mid-Infrared Instrument — JWST instrument detecting mid-infrared wavelengths; used to study atmospheres, cold objects. ESO VLT: European Southern Observatory's Very Large Telescope, Chile — one of the world's most powerful ground-based telescopes. Astronomical Unit (AU): Mean Earth–Sun distance ≈ 150 million km. Light-year: Distance light travels in one year ≈ 9.46 trillion km. Debris disk: Ring of dust, gas, and rocky material around a star, formed from collisions between planetesimals — an indicator of planetary system formation. ✎ Mains Practice Question The discovery of Beta Pictoris d demonstrates a novel method of exoplanet detection using atmospheric spectroscopy. Discuss the significance of this discovery for planetary science and explain the different methods used to detect exoplanets, with their relative advantages and limitations. 15 marks · 250 words 08 Project Kusha: DRDO's Long-Range Surface-to-Air Missile Completes Maiden Flight Test GS-III · S&T — Defence Technology, Indigenisation, Missile SystemsPrelims + MainsThe Indian Express The Defence Research and Development Organisation (DRDO) successfully conducted the maiden flight test of the 'Kusha' Long-Range Surface-to-Air Missile (SAM) on July 23, 2026, at APJ Abdul Kalam Island off the Odisha coast — a significant milestone in India's indigenisation of air defence capabilities. ◈ Background & Context A long-range SAM is typically defined as one with a range exceeding 200 km. India currently operates the Russian-origin S-400 Triumf (capable of engaging targets up to 400 km away) — a platform that has attracted both strategic attention and import-dependency concerns. The test was conducted against an electronic target simulating a high-speed, high-altitude aerial threat, which Kusha successfully intercepted. All weapon system elements — missiles, radars, command and control centre — were developed by DRDO laboratories and domestic industry partners. Defence Minister Rajnath Singh described the test as a milestone that will eliminate India's import dependency for long-range SAM systems. Figure 4 — DRDO Kusha Long-Range SAM: Maiden Flight Test, APJ Abdul Kalam Island The maiden flight of 'Kusha' from APJ Abdul Kalam Island, Odisha, on July 23, 2026. Image: PTI; reproduced for educational use. Project Kusha in India's Air Defence Architecture Threat envelope: Kusha is designed to intercept fighter jets, cruise missiles, UAVs, and large enemy aircraft across a wide range and altitude envelope. IADWS linkage: In 2025, DRDO also tested the Integrated Air Defence Weapon System (IADWS) — a multi-layered system comprising indigenous QRSAM, Advanced VSHORADS missiles, and a high-power laser-based Directed Energy Weapon (DEW). Mission Sudarshan Chakra: Kusha and IADWS together represent building blocks toward a home-grown nationwide multi-domain security shield — the stated goal of Mission Sudarshan Chakra over the next decade. ▤ Key Terms & Prelims Facts SAM (Surface-to-Air Missile): Ground-launched missile designed to destroy aircraft and missiles. APJ Abdul Kalam Island: Formerly Wheeler Island, Odisha; India's premier missile test range. QRSAM: Quick Reaction Surface-to-Air Missile — indigenously developed short-range SAM. VSHORADS: Very Short Range Air Defence System — designed to counter low-flying aerial threats. DEW (Directed Energy Weapon): Weapons using concentrated energy (laser, microwave) to destroy targets — DRDO's high-power laser DEW is a notable indigenous achievement. S-400 Triumf: Russian-origin long-range SAM system; India signed the purchase agreement in 2018; attracted US CAATSA sanctions concerns. ✎ Mains Practice Question India's air defence architecture has historically relied on imported systems. In the context of the successful test of the indigenous 'Kusha' SAM system, discuss the strategic significance of indigenising long-range air defence capabilities and the role of Mission Sudarshan Chakra in achieving this goal. 15 marks · 250 words Environment & EcologyGeneral Studies Paper III 09 Sustainable Cultivation of Kutki (Picrorhiza kurroa): Conservation and Rural Livelihood in the Himalayas GS-III · Environment — Biodiversity Conservation, Medicinal Plants, Sustainable LivelihoodsPrelims + MainsThe Hindu Farmers in Himachal Pradesh's Mandi district, supported by the Himalayan Research Group (HRG), have pioneered a sustainable 'stolon harvest' cultivation model for Kutki (Picrorhiza kurroa) — an endangered alpine medicinal herb — offering both a conservation solution and an additional livelihood source for mountain communities. ◈ Background & Context Picrorhiza kurroa, known locally as Kutki, is a high-value medicinal herb native to the alpine and sub-alpine zones of the Himalayas at altitudes of 2,700–4,500 metres. Used in Ayurvedic formulations, it has been driven to endangerment by decades of destructive wild harvesting — the entire plant (including root) was typically uprooted. Kutki is listed on the IUCN Red List as an endangered species and included in Appendix II of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) — permitting international trade only under regulated conditions with export permits. HRG, a DST-supported body based in Shimla, spent over a decade developing and field-demonstrating the sustainable harvest methodology; it now spans approximately 180 farmers in Mandi district — the largest private land cultivation cluster of this species. The initiative originated as a research project under the Department of Biotechnology's Himalayan Bioresource Mission in 2022. The Stolon Harvest Method The innovative method harvests only the plant's stolons — lateral creeping stems with nodes, technically distinct from roots (which are fibrous and medicinally inert). The mother plant is left intact, allowing it to continue producing stolons for years — converting a destructive annual extraction into a perennial, sustainable yield. After drying, harvested stolons are collected for marketing; farmers earn approximately ₹15,000–₹16,000 annually by producing 5–6 kg of dried herb. A common misconception held that Kutki's root was the drug — in practice, it is the stolon, which the old wild-harvest method destroyed along with the plant. ✎ Mains Practice Question India's biodiversity-rich Himalayan region faces significant pressure from the commercial trade in medicinal plants. Using the case of Kutki (Picrorhiza kurroa), discuss how sustainable cultivation models can simultaneously serve conservation and rural livelihood objectives. What role should regulatory frameworks like CITES play in this context? 15 marks · 250 words 10 Climate Change and Ageing: Structural Vulnerabilities of the Elderly and the Case for People-Centred Adaptation GS-III · Environment — Climate Change Impacts, Disaster Risk ReductionGS-II · Social Issues — Vulnerable Groups, Healthcare, Elderly PolicyPrelims + MainsThe Hindu A HelpAge India study examining climate change's impact on senior citizens finds that the elderly face disproportionate harm from both sudden climate shocks and slow-onset stresses — and that India's hazard-centred disaster response frameworks must shift to people-centred, intersectional systems to address this growing vulnerability. ◈ Background & Context India's elderly population is projected to rise from 149 million in 2022 to approximately 347 million by 2050 — over 20% of the projected population. As the demographic composition shifts, an increasing share of the country becomes structurally exposed to climate-related health challenges. Climate stressors affecting the elderly include: rising temperatures, erratic rainfall, drought, flooding, coastal erosion, indoor heat stress, dampness, and environmental degradation — which together worsen chronic illness, raise mortality risk, reduce mobility, and increase care needs. The report employs an "Intersectional Place Perspective" — recognising that risk is shaped by the interaction of age, gender, widowhood, disability, poverty, social isolation, and local environmental conditions, not by any single factor in isolation. Access barriers for the elderly during climate events: poor health (30%), severe climate-shock experience (30%), no formal education (22%), lower socio-economic group (22%), long wait times (25%), digital access difficulties (15%). Policy Recommendations Shift from hazard-centred to people-centred systems — integrating climate adaptation, healthy ageing, social protection, and disaster risk reduction. Establish climate-resilient healthcare for older persons; expand social protection and livelihood support. Age-inclusive early warning systems and community monitoring networks; stronger local care systems for those living alone or with impairments. Harness the One Health framework; generate better age-disaggregated climate-health data; strengthen institutional coordination. Targeted support for highest-risk groups: those living alone, widows, persons with impairments, the oldest-old, and financially insecure households. ✎ Mains Practice Question Climate change impacts are not socially neutral, and senior citizens represent a disproportionately vulnerable group. Critically examine the intersecting vulnerabilities of the elderly in the context of climate change and suggest an integrated policy framework that connects climate adaptation with healthy ageing and social protection. 15 marks · 250 words
