Skyroot Aerospace's Vikram-1, India's first privately developed orbital launch vehicle, successfully placed technology demonstration satellites in Low Earth Orbit (LEO) from Sriharikota on July 18, 2026, making India only the third country after the US and China with private orbital launch capability. This article explains the Vikram-1 mission and Skyroot Aerospace, what Low Earth Orbit is, how orbital slots and radio frequencies are governed under the Outer Space Treaty and the ITU, the global race for LEO and satellite megaconstellations, India's space sector reforms, IN-SPACe and the Indian Space Policy 2023, the strategic significance of sovereign launch capacity, and the bottlenecks ahead — with UPSC Prelims facts, MCQs and Mains practice questions.

Prime Minister Narendra Modi has flagged off India's first hydrogen-powered train on the 89-km Jind–Sonipat section in Haryana, making India one of a select group of nations operating zero-emission hydrogen rail technology. With 10 coaches carrying up to 2,600 passengers, it is described as the world's most powerful and longest hydrogen train. This article explains the train's features, how hydrogen fuel cell propulsion works, the DEMU retrofit design, the Hydrogen for Heritage scheme, the National Green Hydrogen Mission, global comparisons, and the significance for Indian Railways' decarbonisation, for UPSC Prelims and Mains.

The Union Cabinet has approved Semicon 2.0, the second phase of the India Semiconductor Mission (ISM 2.0), with a total outlay of ₹1,27,500 crore to build India's semiconductor design and manufacturing ecosystem on six pillars. Media reports indicate the Centre will not subsidise land acquisition or technology transfer costs under the new scheme, with states expected to take the lead on land, and capital subsidies for silicon fabs reduced from 50% to 40%. This article explains what semiconductors are, the achievements of ISM 1.0, the six pillars of Semicon 2.0, the revised incentive structure, the role of states, India's chip targets for 2029 and 2035, and the challenges ahead — all from the UPSC Prelims and Mains perspective.

The Gujarat government has announced the Viksit Gujarat Data Centre Policy 2026-29, targeting investments of about ₹6 lakh crore and the creation of 7.5 gigawatts (GW) of data centre capacity — claimed to be the highest in the country. The policy offers tax and duty exemptions, power and water guarantees and building-norm relaxations, mandates that 51% of electricity for core operations come from green energy, and seeks to develop Dholera as a global data centre city. This article explains what data centres and hyperscale AI data centres are, the policy's incentives, the Reliance-Meta Jamnagar project, India's data centre landscape, and the associated energy, water and policy challenges.

The Union Cabinet on 15 July 2026 approved Semicon 2.0, the second phase of the India Semiconductor Mission, with a total outlay of ₹1,27,500 crore to build a complete semiconductor ecosystem across six pillars. The Cabinet also cleared the Mobile Phone Manufacturing Scheme (MPMS) worth ₹62,500 crore as the successor to the PLI scheme for smartphones. This article explains what semiconductors are, the journey of ISM 1.0, the six pillars of Semicon 2.0, the incentive structure of MPMS, India's mobile manufacturing success story, approved chip plants and their locations, and the challenges ahead.

The Union Ministry of Health and Family Welfare (MoHFW) has notified amendments to the Drugs Rules, 1945, expanding the QR code-based track-and-trace framework to cover all vaccines, antimicrobials, anti-cancer medicines and narcotic and psychotropic drugs by bringing them under Schedule H2. The move aims to curb counterfeit and substandard medicines and strengthen India's fight against antimicrobial resistance (AMR). This article explains the new notification, India's drug-regulation framework under the Drugs and Cosmetics Act, 1940, the meaning of various drug schedules, how QR-code traceability works, the law on spurious and substandard drugs, and the AMR connection.

China's LineShine supercomputer has debuted at No. 1 on the TOP500 list of the world's most powerful supercomputers, overtaking the United States' El Capitan system. Announced at the ISC High Performance 2026 conference in Hamburg, Germany, LineShine clocked 2.198 exaflops and is the first machine to cross two exaflops using a CPU-only design built entirely on domestic chips. It is the first China-based system to top the list since Sunway TaihuLight in 2017. This article explains what supercomputers and the LINPACK benchmark are, why a CPU-only Chinese win matters, how US export controls and the US–China tech race shape the result, and where India stands through the National Supercomputing Mission.

The architecture for the global governance of Artificial Intelligence is taking concrete shape in 2026. The United Nations General Assembly has appointed the first-ever Independent International Scientific Panel on Artificial Intelligence, with IIT Madras professor B. Ravindran as its only Indian member, and the first session of the new Global Dialogue on AI Governance is scheduled for July 2026 in Geneva. Alongside this, the India AI Impact Summit 2026 in New Delhi produced the Trusted AI Commons and the New Delhi Declaration on AI Impact, foregrounding the interests of developing nations. This article explains what these institutions are, why a global governance system for AI is needed, the risk of "digital colonies", and how India is positioning itself as a bridge for the Global South.

India’s top atomic energy regulator is expected to maintain rigorous safety and licensing requirements for Small Modular Reactors even as the government prepares rules under the SHANTI Act, 2025. The issue matters because the Act opens India’s tightly controlled civil nuclear sector to private participation, while India is also trying to expand nuclear capacity for clean, round-the-clock power and industrial decarbonisation. The Department of Atomic Energy has earlier stated that AERB’s nuclear safety framework is generally technology-neutral and can be used for both public and private nuclear projects.

A recent Indian Express interview with lawyer and anthropologist Petra Molnar discussed the AI Resist List and warned that AI-led growth narratives can hide issues of invisible labour, data extraction, surveillance, digital infrastructure and democratic accountability. The debate is significant for India as it expands the IndiaAI Mission, data centres, AI compute capacity and digital public infrastructure.

The United States has directed Anthropic to suspend access to its latest AI models, Fable 5 and Mythos 5, for foreign nationals on national-security grounds, forcing the company to disable the models for all users. The issue is important for UPSC because it links frontier AI, export controls, cybersecurity risks, technological sovereignty, global AI governance and India’s need to build indigenous AI capacity.

Anthropic has released Claude Fable 5, a publicly available version of its more powerful Mythos-class AI model, while keeping Claude Mythos 5 restricted for selected trusted users because of risks in cybersecurity, biology, chemistry and model misuse. The issue is important for UPSC because it links frontier AI, dual-use technology, cyber security, data protection, responsible innovation, IndiaAI Mission and global AI governance.
