In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative. AMCA: India’s Indigenous Stealth Fighter Dream The AMCA project , spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) , received its l...
IIT Madras Develops Water-less Concrete for Mars Habitats IIT Madras researchers have developed an innovative water-less concrete that could revolutionize extraterrestrial construction , specifically for building habitats on Mars . This breakthrough is crucial as water is extremely scarce on Mars, making traditional concrete production impractical. Key Highlights of the Breakthrough 1. Why Waterless Concrete for Mars? Water is an essential component in conventional concrete. However, Mars has almost no liquid water , making construction a major challenge. This new concrete eliminates the need for water , making it ideal for extraterrestrial environments. The technology aligns with the "In-Situ Resource Utilization (ISRU)" approach, meaning materials available on Mars can be used to make the concrete . 2. What is Waterless Concrete Made Of? Martian Soil Simulants: Researchers tested the mix using Earth-based materials that mimic Mars' soil (regolith) . Geopolymer Binder...
