🚀 पहली बार वैज्ञानिकों ने किसी क्षुद्रग्रह की कक्षीय अवधि को जानबूझकर बदला। 🚀 NASA का DART मिशन • Target: Dimorphos asteroid • Didymos–Dimorphos system का हिस्सा • Orbital period change: ≈33 minutes • Impact से orbital speed में ≈42 mm/hr की कमी यह प्रयोग दिखाता है कि kinetic impact technique भविष्य में संभावित asteroid threats से निपटने का एक तरीका हो सकती है। 🎯 Exam Angle: DART Mission | Asteroid Deflection | Planetary Defence ➡️ Space Science | NASA | GS-III Sci-Tech ━━━━━━━━━━━━━━━━━━━━ Read → Revise → Respond @CurrentScenario 🔥

🌾 Rights, Justice & Action for India’s Women Farmers India’s women grow the food but rarely own the land. No land title → No credit, crop insurance, or extension support. Agriculture is feminising, yet women remain invisible in policy. 📌 Policy Gap Food security laws exist, but PDS remains cereal-centric and digital systems often exclude rural women. 📌 Key Reforms (MSSRF–WFP) → Gender-disaggregated farm data → Joint land titles & inheritance reform → Nutrition-focused food systems → Tech & extension services for women farmers 🎯 Exam Angle: Women Farmers | Food Security | National Food Security Act, 2013 📎 GS1 (Society) | GS2 (Welfare) | GS3 (Agriculture) ━━━━━━━━━━━━━━━━━━ 📰 Source: The Hindu Read • Revise • Use in Mains @CurrentScenario

🌎 CLIMATE CHANGE vs INTERNATIONAL LAW 1️⃣ Sinking States, Legal Crisis Sea-level rise threatens statehood of small island nations (territory loss). Existing international law has no clear rule if territory disappears. 📌 Prelims: Montevideo Convention (1933), ICJ advisory opinions 📌 GS2: International law & climate governance 2️⃣Climate Refugees – Legal Vacuum 1951 Refugee Convention does NOT recognise climate refugees. Experts propose UNFCCC-based protocol for protection & resettlement. 📌 Prelims: Refugee Convention 1951, UNFCCC 📌 GS2/GS3: Climate migration & global governance 3️⃣ Maritime Zones at Risk Sea-level rise may shift baselines → EEZ, territorial sea, continental shelf. Could reshape global maritime boundaries. 📌 Prelims: UNCLOS, Baseline concept 📌 GS2/GS3: Ocean governance & climate change 🎯 Exam takeaway: Climate change → challenges statehood, migration law & maritime sovereignty. @CurrentScenario 🔥
