3.5-Billion-Year-Old Mars Crater
Source: TH Context: The International Astronomical Union (IAU) has approved naming a 3.5 billion-year-old crater on Mars after M.S. Krishnan, one of India’s pioneering geologists. The proposal was submitted by two Kerala-based researchers and marks a significant recognition of Indian scientific heritage in planetary nomenclature. Mars Craters A crater on Mars is a circular depression formed primarily by the impact of meteoroids, asteroids, or comets striking the surface. Notable Craters on Mars: Crater Name Location/Region Significance Gale Crater Aeolis region Landing site of Curiosity Rover; evidence of ancient water Jezero Crater Syrtis Major Planum Landing site of Perseverance Rover; ancient river delta Huygens Crater Southern hemisphere Large, heavily eroded crater Hellas Basin Southern hemisphere One of the largest impact basins in the Solar System Gusev Crater Near Martian equator Explored by Spirit Rover; past water flows Mars Crater Named ‘Krishnan Crater’ Kerala Place Names Adopted on Mars IAU approved several Kerala-based names for smaller Martian features associated with the crater: These names will represent smaller craters and a vallis (valley), creating Martian counterparts of well-known Kerala locations.
Corporate Average Fuel Efficiency (CAFE-III)
Source: BS Context: The third edition of Corporate Average Fuel Efficiency (CAFE-III) norms, set to apply between FY28 and FY32, has reignited debate in the Indian automobile industry. While intended to cut fleet-wide CO₂ emissions and improve fuel efficiency, the draft norms raise questions beyond affordability, touching on urban pollution, public health, safety standards, and market structure. CAFE Norms CAFE-III refers to the third phase of Corporate Average Fuel Efficiency norms for automobiles in India. These norms set fleet-wide fuel efficiency and CO₂ emission standards that vehicle manufacturers must meet. Essentially, it requires manufacturers to ensure that the average fuel efficiency of all vehicles they sell meets a specified target. Key Features

Planting 6 Ideas for a Resilient Agriculture in India
Source: ET Context: Despite being a leading global producer of key crops, Indian agriculture faces challenges including rain dependence, fragmented landholdings, limited credit access, technology gaps, post-harvest losses, and market volatility. To build a resilient and profitable farming ecosystem, structural reforms and market-oriented strategies are crucial. Six Key Ideas for Agri-Resilience:
Harnessing Artificial Intelligence for Agricultural Transformation: World Bank Report
Source: World Bank Context: Current Trends in AI for Agriculture Opportunities of AI in Agriculture Area Benefits Productivity Precision farming, irrigation, fertilizer tools; yield increase 20–30%, chemical use reduction up to 95%. Climate Resilience AI-assisted breeding, risk modeling, cropping pattern planning. Income & Market Access Initiatives like Saagu Baagu (India) and Hello Tractor enhance productivity and optimize machinery use. Inclusive Finance & Risk Mitigation AI-driven micro-insurance, alternative credit scoring for unbanked smallholders. Public Policy Early-warning systems, yield & price forecasts, and targeted subsidies for food security planning. Key Initiatives Already Taken Key Challenges Challenge Details Digital Divide & Infrastructure Gaps Limited internet/electricity access in rural LMICs. Data Bias & Scarcity Most training data from high-income regions; local crops and practices underrepresented. Low Human Capital & Trust Limited digital skills; language barriers; distrust of automated advice. Weak Governance & Regulation Lack of clear rules on data ownership, privacy, and algorithm accountability. Risk of Exclusion & Concentration AI could favor large agribusinesses and deepen inequalities without safeguards. Way Ahead
