Parliament is debating the SHANTI Bill. This Sunday edition consolidates its architecture for study.

• Full name: Sustainable Harnessing of Advancement of Nuclear Energy for Transforming India Act 2025.
• What it replaces: The Atomic Energy Act 1962 and associated rules.
• Private sector access: Licensed private companies may enter uranium mining, fuel fabrication, reactor construction, electricity generation and radioactive waste management.
• AERB replacement: The Atomic Energy Regulatory Board (AERB) was established in 1983. It operates under the Department of Atomic Energy. The SHANTI Bill converts it into a statutory independent Nuclear Safety Authority (NSA) with its own enabling legislation. This resolves the regulator-promoter conflict.
• Nuclear tribunal: A dedicated tribunal for liability disputes. Currently, claimants must approach civil courts under the Civil Liability for Nuclear Damage Act 2010 (CLNDA). Section 46 of CLNDA preserved the right to sue under other law, which suppliers found unpredictable.
• SMR definition: The Bill defines Small Modular Reactors as reactors up to 300 MW. SMRs can be factory-built and transported. They are suited to industrial process heat, remote communities and coal-plant replacement.
• Liability alignment: The Bill is expected to align India's liability regime with the Vienna Convention on Civil Liability for Nuclear Damage (1963), which caps operator liability and channels it away from equipment suppliers.
• 100 GW target: India currently operates about 7.5 GW of nuclear capacity. The 2047 Viksit Bharat target of 100 GW requires at least 10x expansion.

The LVM3 launch window for BlueBird-6 opens 15 December. This is an opportunity to consolidate static knowledge about India's heaviest operational rocket.

• Full name: Launch Vehicle Mark-3. Formerly called GSLV Mk III.
• Stages: Three stages. A liquid-fuelled core stage (L110) flanked by two solid strap-on boosters (S200) at liftoff, and a cryogenic upper stage (C25) using liquid oxygen and liquid hydrogen.
• Payload capacity: Approximately 10 tonnes to Low Earth Orbit. Approximately 4 tonnes to Geosynchronous Transfer Orbit.
• Height: 43.5 metres. Lift-off mass approximately 640 tonnes.
• Operational history: Chandrayaan-2 (2019), Chandrayaan-3 (2023), OneWeb broadband satellite batches (2022-2023) and now BlueBird-6.
• Cryogenic advantage: The C25 upper stage is India's indigenously developed cryogenic engine (CE-20). Cryogenic stages are essential for GTO missions.
• Commercial arm: NewSpace India Limited (NSIL) is ISRO's commercial entity. It markets LVM3 and PSLV to foreign satellite operators.
• IN-SPACe role: Indian National Space Promotion and Authorisation Centre regulates private space players in India. It issues authorisations under the Space Activities Policy 2017 framework.

Static linkage: ISRO; NSIL; IN-SPACe; Space Policy 2023; Outer Space Treaty 1967.

The Supreme Court is hearing a petition on the protection of Aravalli land from construction. The Court accepts the 100-metre elevation criterion for identifying Aravalli terrain.

• Aravalli Range basics: One of the world's oldest fold mountain ranges. Extends approximately 692 km from Himmatnagar in Gujarat through Rajasthan and Haryana to Delhi.
• Ecological functions: Groundwater recharge for the Gangetic plain and Indus basin. Wind barrier that reduces dust intrusion into Delhi from the Thar Desert. Habitat for the leopard, hyena, jackal and more than 200 bird species.
• Legal dispute: Private builders and state governments have classified Aravalli land as non-forest to permit construction. The SC intervention follows decades of encroachment.
• 100-metre criterion: The Court accepts that land at or above 100 metres elevation in the mapped Aravalli zone should be treated as protected for environmental purposes.
• 1992 Aravalli Notification: A notification under the Environment Protection Act 1986 prohibits mining in the Aravalli range in Haryana. This is the core legal instrument under challenge.
• Save Aravalli campaign: Led by civil society groups in Haryana and Rajasthan to stop housing projects on Aravalli land.

INS Taragiri is commissioned as the third stealth guided-missile frigate in Project 17A. It is built at Mazagon Dock Shipbuilders Limited, Mumbai.

• Project 17A: A programme to design and build seven stealth frigates for the Indian Navy. The project is built on lessons from the earlier Project 17 (Shivalik class).
• Builder: Mazagon Dock Shipbuilders Limited (MDL), Mumbai for four ships. Garden Reach Shipbuilders and Engineers (GRSE), Kolkata for the remaining three.
• Stealth features: Radar cross-section is minimised by sloped hull surfaces, enclosed weapon systems and radar-absorbent coatings. Engine vibrations are isolated using special mounts.
• Displacement: Approximately 6,670 tonnes.
• Armament: BrahMos supersonic cruise missiles; medium-range surface-to-air missiles; torpedo tubes; a 76 mm OTO Melara gun.
• Significance: INS Taragiri's commissioning strengthens India's blue-water capability at a time of heightened Indian Ocean competition.
• Naming convention: Named after a peak in the Himachal Pradesh Himalayas, continuing the tradition of naming Project 17A ships after Indian mountain peaks.

World Soil Day was observed on 5 December. India's Soil Health Card Scheme is a recurring prelims topic linked to soil health and sustainable agriculture.

• Scheme launch: February 2015 by Prime Minister Modi in Suratgarh, Rajasthan.
• Ministry: Ministry of Agriculture and Farmers Welfare.
• Objective: Test the soil of every farm in India once every two years. Issue a Soil Health Card with nutrient status and fertiliser recommendations.
• Coverage: More than 22 crore soil health cards distributed by 2023.
• Parameters tested: 12 parameters including NPK (nitrogen, phosphorus, potassium), secondary nutrients (sulphur, calcium, magnesium) and micronutrients (boron, zinc, iron, manganese, copper).
• Outcome: Reduces input cost by encouraging site-specific fertiliser use rather than blanket application. Curbs overuse of urea.
• NITI Aayog target: India aims to bring 5 million hectares of degraded land under restoration annually to meet its LDN (Land Degradation Neutrality) commitment under the UNCCD.

The Geminid meteor shower reaches its annual peak on the night of 13-15 December 2025.

• Radiant: Constellation Gemini, near the star Castor.
• Peak rate: 100 to 120 meteors per hour under clear, dark skies.
• Parent body: Asteroid 3200 Phaethon. Not a comet. All other major annual meteor showers (Perseids from Swift-Tuttle, Leonids from Tempel-Tuttle, Eta Aquarids from Halley) originate from comets.
• 3200 Phaethon: Has an unusual orbit that takes it closer to the Sun than Mercury. Solar heating causes thermal fracturing that releases debris. It is classified as a Potentially Hazardous Asteroid (PHA).
• Viewing tip: The shower is visible from both hemispheres but best above the equator. Best time is after midnight local time. No optical aid needed.
• India context: ISRO's Aditya-L1 solar observatory is positioned at the Sun-Earth L1 point. It monitors solar activity that affects near-Earth space weather. Asteroid tracking is handled by the NETRA (Network for Space Objects Tracking and Analysis) facility.

The saiga antelope's downlisting at CITES CoP20 is one of conservation's most remarkable recovery stories.

• Species: Saiga tatarica. A critically shaped antelope native to the Eurasian steppe.
• Population crash: In the early 2000s, populations collapsed to fewer than 50,000 due to poaching (for its horn) and a catastrophic bacterial disease (Pasteurellosis).
• Recovery: By 2024, the total saiga population in Central Asia exceeds 1.9 million.
• Reasons for recovery: Strong international anti-poaching cooperation. Protective measures by Kazakhstan, Russia, Mongolia and Uzbekistan. Range-wide monitoring by CMS (Convention on Migratory Species).
• CITES Appendix change: Downlisted from Appendix II to a lower protection level reflecting the successful recovery.
• Conservation lesson: The saiga case demonstrates that species can recover rapidly with political will and coordinated cross-border action.
• India connection: India is home to the Tibetan antelope (Chiru), which faces similar poaching pressure for its wool (shahtoosh). The saiga story is analytically comparable.

India and Oman are in active negotiations for a Comprehensive Economic Partnership Agreement. Geopolitical and strategic dimensions add weight to the talks.

• Bilateral trade: Approximately USD 12 billion annually. India exports refined petroleum, machinery and pharmaceuticals. Oman exports LNG, crude oil and metals.
• Joint ventures: Around 6,000 India-Oman joint ventures are operational in Oman.
• Duqm port: The Port of Duqm on Oman's Arabian Sea coast provides the Indian Navy with access for logistics and maintenance. This is part of India's Indian Ocean basing access strategy.
• RuPay in Oman: India launched RuPay card acceptance in Oman in 2022. An MoU between NPCI International and Oman's network enables this.
• CEPA context: India has signed CEPAs with UAE (2022) and Mauritius (2021) in recent years. The Oman CEPA would add a key Gulf partner.
• Strategic relevance: Oman does not join rival blocs. It maintains diplomatic ties with Iran, Israel and India simultaneously. It is one of the most stable Gulf states for Indian interests.

Static linkage: India-Gulf Relations; CEPA framework; NPCI International; Indian Ocean Strategy; Duqm port.

• NETRA facility: India's Network for Space Objects Tracking and Analysis (NETRA) at Hassan in Karnataka monitors near-Earth objects and debris. It was operationalised by ISRO in 2022.
• Aravalli 1992 notification: Issued under the Environment Protection Act 1986. It bans all forms of mining in the Aravalli range in Haryana. The notification predates the Forest Conservation Act regime and applies independently.
• CLNDA Section 17(b): The right-to-recourse clause under the Civil Liability for Nuclear Damage Act allowed the operator to recover compensation costs from the equipment supplier if defective equipment caused the accident. International nuclear suppliers found this clause unprecedented. SHANTI is expected to align this with the Vienna Convention approach.
