Current Affairs — 21 October 2026

1. Ladakh Gets Its Own High Court Bench at Leh

Basic Concept

Ladakh became a Union Territory without a legislature in August 2019, sharing the "Jammu & Kashmir and Ladakh High Court" with J&K; until now, Ladakhi litigants had to travel to Srinagar or Jammu for High Court matters. Setting up a permanent "Bench" of an existing High Court at a new location (distinct from a separate High Court) decentralises access to justice without needing a new court altogether.

Core Context

Chief Justice of India Surya Kant inaugurated the new Ladakh Bench of the J&K and Ladakh High Court at Melongthang, Leh — described as India's highest-altitude High Court bench. Regular case sittings began on 21 October 2026 with 105 cases listed on the first day. The CJI also launched an e-filing portal, a digital case/document management system, and an online judicial recruitment portal, and said Ladakh-related Supreme Court matters would be listed together with scope for video-conferenced hearings.

Latest Developments

• This is the first-ever dedicated High Court bench physically located within Ladakh since it became a separate Union Territory in 2019.

• The e-filing and digital case-management systems aim to reduce the travel and paperwork burden that previously fell on Ladakhi litigants and lawyers.

• The move complements separate, ongoing talks between Ladakhi groups and the Centre over political autonomy and statehood demands, but addresses judicial access specifically rather than legislative powers.

UPSC Prelims Pointers

• The Ladakh Bench is located at Melongthang, Leh, and is described as India's highest-altitude High Court bench.

• Ladakh shares its High Court with Jammu & Kashmir, officially the "Jammu & Kashmir and Ladakh High Court."

• Regular sittings at the Ladakh Bench began on 21 October 2026.

2. Turkiye, Qatar, Pakistan and Indonesia Sign the "Badr" Defence Cooperation Accord

Basic Concept

Several Muslim-majority middle powers have been deepening defence-industrial cooperation in recent years amid Gulf security anxieties (Houthi attacks, tension in the Strait of Hormuz) and shifting regional alignments after the Gaza conflict. All four countries involved here are members of the Organisation of Islamic Cooperation (OIC), and Pakistan-Turkiye defence ties already include transfers like MILGEM-class corvettes to the Pakistan Navy.

Core Context

Turkiye, Qatar, Pakistan, and Indonesia signed a defence cooperation accord, dubbed the "Badr Memorandum of Understanding," on 21 October 2026, with Ankara announcing the pact to expand defence-industrial cooperation and joint production capacity among the four countries.

Latest Developments

• The accord is aimed at expanding joint defence-industrial production capacity, not merely issuing a political statement.

• For India, it is significant as it strengthens a Turkiye-Pakistan-Qatar-Indonesia axis, relevant to assessing India's extended-neighbourhood security environment.

• It follows a pattern of Pakistan diversifying and deepening defence partnerships beyond its traditional reliance on China.

UPSC Prelims Pointers

• The "Badr MoU" was signed by Turkiye, Qatar, Pakistan, and Indonesia on 21 October 2026.

• All four signatory countries are members of the Organisation of Islamic Cooperation (OIC).

• Pakistan has previously received MILGEM-class (Jinnah-class) corvettes from Turkiye under earlier defence cooperation.

3. India's Core Sector Output Grows 7.9% in September 2026 — a 13-Month High

Basic Concept

The Index of Eight Core Industries — coal, crude oil, natural gas, refinery products, fertilizers, steel, cement, and electricity — is compiled monthly by the Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce & Industry, and carries roughly 40% weight in the overall Index of Industrial Production (IIP), making it a key leading indicator of industrial health released ahead of the full IIP.

Core Context

Core-sector output grew 7.9% year-on-year in September 2026, released around 21 October 2026, up sharply from 5.9% in August 2026 and marking roughly a 13-month high, led by electricity, refinery products (up 10.3%), iron ore, and coal.

Latest Developments

• Refinery product output specifically rose 10.3% year-on-year in September 2026.

• Electricity and iron ore were cited as other key drivers of the acceleration.

• The 13-month-high framing suggests broader industrial momentum heading into the festive-season demand period.

UPSC Prelims Pointers

• The Eight Core Industries are: Coal, Crude Oil, Natural Gas, Refinery Products, Fertilizers, Steel, Cement, and Electricity.

• Core-sector data is released monthly by DPIIT, ahead of the broader IIP release.

• September 2026 core-sector growth (7.9%) was up from August 2026 (5.9%).

4. GRAP Stage-I Invoked Across Delhi-NCR as Air Quality Slips to "Poor" Post-Dussehra

Basic Concept

The Graded Response Action Plan (GRAP), implemented by the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM, created by a 2021 Act replacing the earlier EPCA), has four stages triggered by Air Quality Index (AQI) thresholds: Stage I at AQI 201-300 ("Poor"), rising through Severe and Severe+ categories, each mandating progressively stricter curbs on construction, vehicles, and industry.

Core Context

CAQM invoked GRAP Stage-I across Delhi-NCR on 21 October 2026 as Delhi's AQI rose to 244 ("Poor" category), attributed to post-Dussehra firecrackers, vehicular emissions, early stubble burning, and adverse winter meteorology (falling wind speed and temperature inversion).

Latest Developments

• GRAP Stage-I curbs include restrictions on open burning, enhanced mechanised road sweeping and water sprinkling, stricter monitoring of construction dust, and action against visibly polluting vehicles.

• This is typically the opening stage of a pollution cycle that intensifies through the Diwali and post-harvest stubble-burning period in late October and November.

• The episode illustrates the recurring governance challenge of coordinating curbs across multiple state governments and agencies within the NCR.

UPSC Prelims Pointers

• GRAP's four stages are triggered by AQI bands: Stage I (201-300, Poor), Stage II (301-400, Very Poor), Stage III (401-450, Severe), Stage IV (above 450, Severe+).

• CAQM was established by a 2021 Act, replacing the earlier Environment Pollution (Prevention and Control) Authority (EPCA).

• Delhi's AQI on 21 October 2026 was recorded at 244, placing it in the "Poor" category.

5. CISF to Shift from Territorial to Sector-Specific Commands from 1 November

Basic Concept

The Central Industrial Security Force (CISF), established in 1969 under the Ministry of Home Affairs with roughly 2.7 lakh personnel, guards critical infrastructure such as airports, ports, metros, PSUs, and nuclear and space installations. It has historically organised itself through geography-based (territorial) field commands.

Core Context

The Ministry of Home Affairs approved CISF's shift from territorial commands to sector-specific functional commands, effective 1 November 2026, so that installations with similar risk profiles — power, coal, steel, petroleum, gas, government buildings, heritage monuments, and mass transit — are grouped under one specialised command regardless of geography. Two new coastal commands are also being created: a "West Coast Port Sector" (Mumbai-based) and an "East Coast Port Sector" (Chennai-based), together covering roughly 250 major and minor seaports.

Latest Developments

• CISF became the nodal agency for seaport security (Recognised Security Organisation status) in 2025, and currently secures major ports including JNPT and Mundra.

• Airports, space facilities, and atomic energy installations already have dedicated commands and are unaffected by this specific reorganisation.

• The restructuring aims to apply uniform, risk-specific security protocols across similar facility types nationwide rather than varying by region.

UPSC Prelims Pointers

• CISF is a Central Armed Police Force (CAPF) under the Ministry of Home Affairs, distinct from border-guarding forces like the BSF.

• The sector-based restructuring takes effect from 1 November 2026.

• CISF has roughly 2.7 lakh personnel and became India's nodal seaport-security agency in 2025.

6. India's Push on Pumped Storage Hydropower as Non-Fossil Capacity Nears 60% of the 2030 Target

Basic Concept

India's NDC (Nationally Determined Contribution) target is 500 GW of non-fossil (renewable, nuclear, and large hydro) electricity capacity by 2030. Pumped Storage Hydropower (PSH) is a grid-balancing storage technology that uses surplus daytime solar power to pump water uphill, releasing it to generate electricity during demand peaks, making it a key "firming" technology for integrating variable solar and wind power.

Core Context

The Ministry of Power and Central Electricity Authority renewed emphasis on scaling up pumped storage hydropower capacity, noting that India's non-fossil capacity has already crossed 300 GW (about 60% of the 500 GW 2030 target), with solar, wind, hydro, bio-power, and nuclear together making up this base.

Latest Developments

• Non-fossil sources now account for over 54% of India's total installed electricity capacity of roughly 552 GW.

• As renewable (especially solar) capacity grows, storage technologies like pumped hydro become essential to manage the variability of supply across the day.

• Examples of existing or upcoming pumped storage projects include those at Tehri and Srisailam.

UPSC Prelims Pointers

• India's NDC target is 500 GW of non-fossil electricity capacity by 2030.

• Pumped Storage Hydropower (PSH) uses surplus power to pump water uphill, releasing it later to generate electricity on demand.

• Non-fossil sources currently make up over 54% of India's total installed capacity.

7. Aditya-L1 Produces First Doppler Velocity Images of the Solar Corona

Basic Concept

Aditya-L1 is ISRO's first dedicated solar observatory, placed at the Sun-Earth L1 Lagrange point (about 1.5 million km from Earth) since January 2024, from where it can continuously observe the Sun without the eclipses a near-Earth orbit would cause. Its Visible Emission Line Coronagraph (VELC) payload continuously images the solar corona, the Sun's outer atmosphere.

Core Context

Scientists at the Indian Institute of Astrophysics (IIA), Bengaluru, used VELC data to produce the first Doppler velocity images of the solar corona, offering new insight into the direction and propagation of solar eruptions and coronal mass ejections (CMEs).

Latest Developments

• This is the first-of-its-kind Doppler velocity mapping of the corona using VELC, showing how CMEs travel directionally away from or along the Sun.

• It builds on earlier Aditya-L1/VELC observations of coronal mass ejection events published by ISRO.

• Better space-weather forecasting is increasingly important given CMEs' potential to disrupt satellites, power grids, and GPS systems that India's economy increasingly depends on.

UPSC Prelims Pointers

• Aditya-L1 was launched in September 2023 (on a PSLV) and reached the L1 Lagrange point in January 2024.

• VELC stands for Visible Emission Line Coronagraph, Aditya-L1's key payload for imaging the solar corona.

• The L1 Lagrange point allows uninterrupted observation of the Sun.

8. Japan Launches MMX Mission to Sample Mars's Moon Phobos

Basic Concept

Phobos is one of Mars's two small moons (with Deimos); scientists debate whether it is a captured asteroid or debris from an ancient impact, a question a sample-return mission can help resolve. JAXA is Japan's space agency, and H3 is its new flagship heavy-lift rocket, successor to the H-IIA.

Core Context

JAXA launched its Martian Moons eXploration (MMX) spacecraft on an H3 rocket from Tanegashima Space Center on 20 October 2026, aiming to land on Phobos, collect at least 10 grams of surface material, and return the sample to Earth by 2031 — the first-ever sample-return mission from a moon of Mars. The mission will also conduct a flyby of Deimos.

Latest Developments

• This would be the first sample-return mission from the Mars moon system, distinct from Mars-surface sample missions like NASA's Perseverance.

• The mission comes amid an active global race to explore the Mars system, alongside NASA, ESA, and China's Tianwen missions.

• Japan's earlier Hayabusa2 mission successfully returned samples from the asteroid Ryugu in 2020, giving JAXA prior sample-return experience.

UPSC Prelims Pointers

• MMX stands for Martian Moons eXploration; it launched on 20 October 2026 aboard an H3 rocket.

• Phobos orbits Mars faster and closer than any other moon orbits its planet in the solar system.

• MMX aims to collect at least 10 grams of Phobos regolith and return it to Earth by 2031.

9. SBI Data Breach: Nearly 3,900 Customer Records Exposed on the Dark Web

Basic Concept

Banking data breaches raise questions under India's cybersecurity governance framework: CERT-In (the Indian Computer Emergency Response Team, under MeitY) mandates reporting of cyber incidents within six hours under its 2022 directions, while the Digital Personal Data Protection Act, 2023 governs how "Data Fiduciaries" like banks must handle personal data, including breach notification once its rules are fully in force.

Core Context

State Bank of India (SBI) confirmed that a preliminary analysis found 3,897 customer records — including names, phone numbers, addresses, and other personal details — exposed on the dark web, reported around 21 October 2026. The bank disclosed the incident to SEBI and stock exchanges as a listed company and engaged a CERT-In-empanelled agency for forensic assessment, stating there was no impact on core banking or business continuity.

Latest Developments

• The 3,897 figure emerged from a larger set of roughly 3.75 lakh records reviewed on the dark web following a hacker's claim.

• Exposed data reportedly included names, mobile numbers, dates of birth, email addresses, branch details, and loan-related information.

• The Internet Freedom Foundation (IFF), a digital rights group, publicly criticised SBI for allegedly not directly notifying affected customers.

UPSC Prelims Pointers

• CERT-In mandates reporting of cyber incidents within six hours under its 2022 directions.

• The Digital Personal Data Protection Act, 2023 is India's principal data-protection law governing "Data Fiduciaries" such as banks.

• SBI confirmed roughly 3,897 customer records were found exposed on the dark web.

10. AI-Designed Viruses Used to Treat a Drug-Resistant Bacterial Infection for the First Time

Basic Concept

Antimicrobial Resistance (AMR) is a top-ten global health threat flagged by the WHO; bacteriophages ("phages") are viruses that specifically infect and kill bacteria, and have long been explored (since before antibiotics, notably at Georgia's Eliava Institute) as an alternative when antibiotics fail. Generative-AI models for designing proteins and genomes are now being applied to design novel phages on demand, an emerging "generative biology" frontier.

Core Context

A US biotech startup reportedly modified a bacteriophage called T7 (which normally infects only E. coli) using an AI design tool to treat a patient with an antibiotic- and existing-phage-resistant E. coli infection, described as a first-of-its-kind human use of an AI-designed virus for therapy, under FDA authorisation. The treatment's outcome is not yet known, and the technical details have not been independently peer-reviewed.

Latest Developments

• The underlying AI model is reported to have generated hundreds of thousands of candidate virus genomes, from which a small number were synthesised and found to be viable in the lab — exact figures remain unverified by independent outlets and should be treated cautiously.

• The case illustrates how AI-assisted biological design is moving from computational prediction toward real clinical application.

• Independent experts not involved in the work have not yet verified the claims, underscoring the need for peer-reviewed publication before drawing firm conclusions.

UPSC Prelims Pointers

• Bacteriophages are viruses that specifically infect bacteria; phage therapy predates antibiotics.

• Antimicrobial Resistance (AMR) is listed among the WHO's top-ten global health threats.

• This is reported as the first human use of an AI-designed phage to treat a drug-resistant infection.

11. Pakistan Test-Fires an Extended-Range Variant of the Fatah-II Missile

Basic Concept

Pakistan's Fatah-series weapons are guided multi-launch rocket systems (quasi-ballistic, short-range) developed partly to penetrate India's layered air-defence architecture, which includes the Russian S-400 Triumf system and indigenous systems like Akash and Barak-8/MR-SAM. The original Fatah-II was first tested in 2023.

Core Context

Pakistan's Army Rocket Force Command test-fired an extended-range variant, reported as "Fatah-II ER," featuring upgraded navigation and avionics over the original Fatah-II.

Latest Developments

• Pakistan claims improved precision-navigation and avionics for the extended-range variant, though independent analysts have not verified claims of near-hypersonic terminal speeds for some variants.

• Analysts frame the test as part of Pakistan's effort to counter India's evolving multi-layered air-defence systems.

• The test fits into a broader regional pattern of both India and Pakistan continuously upgrading missile and air-defence capabilities.

UPSC Prelims Pointers

• Fatah-I and Fatah-II are Pakistani Guided Multi-Launch Rocket Systems (GMLRS), quasi-ballistic in trajectory.

• India's layered air-defence architecture includes the S-400 Triumf (Russia), Akash, and Barak-8/MR-SAM (indigenous).

• The original Fatah-II was first tested by Pakistan in 2023.

12. "Heat Storms": New Climate Research Redefines Super-Sized Heat Waves

Basic Concept

A conventional heat wave is usually defined as five or more consecutive days of abnormally high temperatures in a region. New climate research introduces the term "heat storm" for a heat wave that, at its peak, covers at least 1% of the globe's surface (roughly half of Canada's area) — a way to capture the growing scale and interconnectedness of extreme-heat events amid global warming.

Core Context

A major data investigation analysing hourly global temperatures since 1960 found that "heat storms" have become dramatically more frequent, rising from an average of about 5 per year in the 1960s to about 102 per year in the current decade — roughly a 20-fold increase. The largest on record, dubbed "Heat Storm Vera," lasted 367 days (2023-2024) and covered nearly 85% of the globe at its peak.

Latest Developments

• A separate heat "cascade" that began on 6 July 2008 has continued for more than 18 years, while "Heat Storm Raimundo," which began on 28 February 2026, has already touched almost three-quarters of the planet.

• Heat is estimated to kill almost half a million people globally each year.

• Atmospheric CO2 has risen over 30% since the 1960s, a key driver of the rising frequency and scale of such events.

UPSC Prelims Pointers

• A "heat storm," per this new research, is a heat wave covering at least 1% of the globe's surface at its peak.

• Heat storm frequency rose from about 5 per year in the 1960s to about 102 per year in the current decade.

• "Heat Storm Vera" (2023-24) is the largest on record, lasting 367 days and covering nearly 85% of the globe.

13. India Adds Three New Sites to UNESCO's World Heritage Tentative List

Basic Concept

The "Tentative List" is the mandatory first step before a country can nominate a site for full UNESCO World Heritage inscription; a site must remain on it for at least a year before a full nomination dossier can be submitted. India manages its list through the Archaeological Survey of India (ASI) and the Ministry of Culture, and currently has 43 inscribed World Heritage Sites.

Core Context

India added three new sites to its UNESCO Tentative List: the Karst-and-Mud-Volcano Complex of Baratang (Andaman & Nicobar Islands), the Andaman Subduction Volcanoes (including Barren Island, South Asia's only confirmed active volcano), and the Sirpur Cultural and Archaeological Landscape in Chhattisgarh, an ancient Buddhist and temple site on the Mahanadi river. This takes India's Tentative List total to 81 sites.

Latest Developments

• Barren Island, part of the Andaman Subduction Volcanoes site, is the only confirmed active volcano in South Asia.

• Baratang's mud volcanoes and limestone caves are tied to the active Indo-Burma tectonic subduction zone.

• Sirpur (Chhattisgarh) is significant for early-medieval Buddhist and temple architecture, already a Monument of National Importance.

UPSC Prelims Pointers

• India's UNESCO Tentative List now totals 81 sites, while its inscribed World Heritage Sites number 43.

• Barren Island (Andaman & Nicobar Islands) is South Asia's only confirmed active volcano.

• A site must stay on the Tentative List for at least one year before a full nomination dossier can be submitted.

14. PM-SETU Scheme: ₹1,194.92 Crore Approved for Five New ITI Clusters

Basic Concept

PM-SETU (PM's Scheme for Employment and Training Upliftment), under the Ministry of Skill Development and Entrepreneurship (MSDE), upgrades Industrial Training Institutes (ITIs) into "Centres of Excellence" or clusters through industry partnership and co-investment, aligning vocational training curricula with current industrial needs. ITIs provide vocational training typically after Class 10 or 12, distinct from diploma-level Polytechnics.

Core Context

The National Steering Committee under PM-SETU approved five new investment plans worth about ₹1,194.92 crore to upgrade 25 ITIs across Maharashtra, Odisha, and Jammu & Kashmir, taking the scheme's cumulative sanctioned investment to roughly ₹3,687 crore (a cumulative figure reported in some coverage but not independently cross-verified against a second source).

Latest Developments

• The scheme model emphasises industry co-investment to modernise ITI infrastructure and align training with current industrial skill demands.

• This round of approvals covers 25 ITIs spanning two states and one Union Territory.

• PM-SETU forms part of India's broader skilling push, complementing other schemes under the Ministry of Skill Development and Entrepreneurship.

UPSC Prelims Pointers

• PM-SETU falls under the Ministry of Skill Development and Entrepreneurship (MSDE).

• The latest approval was for about ₹1,194.92 crore, covering 25 ITIs in Maharashtra, Odisha, and Jammu & Kashmir.

• ITIs (Industrial Training Institutes) provide vocational training typically after Class 10 or 12.
