GK One-Liners

What: TARA (Tactical Advanced Range Augmentation) is India’s first indigenous glide weapon and modular range-extension kit. Developed by the Research Centre Imarat (RCI), a laboratory under the Defence Research and Development Organisation (DRDO) based in Hyderabad, it converts 250 kg, 450 kg, and 500 kg unguided gravity bombs into precision-guided munitions.

How: TARA uses a combination of Inertial Navigation System (INS), Global Positioning System (GPS), and electro-optical guidance to achieve stand-off strike capability. Its maiden trial was conducted off the coast of Odisha, demonstrating the ability to engage targets at extended ranges without putting the launch aircraft in a threat zone.

Why: This is a major milestone for India’s defence self-reliance under the Atmanirbhar Bharat initiative. UPSC and state PSC exams frequently test DRDO breakthroughs, weapons systems, and indigenisation milestones. The keyword “modular range extension kit” and the trial location (Odisha coast) are typical one-liner facts.

What: During Vietnamese President To Lam’s visit to India (May 5–7, 2026), the bilateral relationship was elevated to an Enhanced Comprehensive Strategic Partnership (CSP). The two sides signed 13 Memoranda of Understanding (MoUs) and 27 cooperation agreements, setting a bilateral trade target of USD 25 billion by 2030.

How: PM Modi and President To Lam met at Hyderabad House, New Delhi. The MoUs cover sectors including digital technologies, culture, health regulation, education, tourism, and public sector cooperation. Agreements were also formalised in Mumbai, underscoring growing economic integration.

Why: India–Vietnam ties are a recurring topic in UPSC International Relations given Vietnam’s strategic position in the Indo-Pacific and ASEAN. Key recall facts: 13 MoUs, USD 25 billion trade target, “Enhanced CSP” upgrade, and PM Modi’s venue (Hyderabad House). This is also relevant for questions on India’s Act East Policy.

What: The National Crime Records Bureau (NCRB) released its annual Crime in India 2024 report, showing India’s overall crime rate declined from 448.3 per lakh population in 2023 to 418.9 in 2024. Total cognisable offences registered stood at 35.44 lakh, and 1,70,746 suicides were recorded during the year.

How: Among the 19 metro cities surveyed, Delhi topped the list with 2,75,402 cognisable offences. The NCRB, which functions under the Ministry of Home Affairs (MHA), compiles this annual report by aggregating data from state police forces and Union Territory administrations across India.

Why: NCRB data is a standard source for GS-II questions on internal security, law enforcement, and social issues. Examiners frequently ask about the city with the most registered crimes and the trend in national crime rates. The suicide data also feeds into questions on social welfare and mental health policy.

What: A NITI Aayog report on school education revealed that India has 14.71 lakh (1.47 million) schools enrolling over 24 crore (240 million) students, making it the world’s largest school education system. However, approximately 8,000 “ghost schools” — institutions with zero student enrolment — were identified across the country.

How: The state-wise distribution of ghost schools shows West Bengal leading with 3,812, followed by Telangana (2,245), Jammu & Kashmir (146), and Punjab (13). These schools continue to exist on government records and consume administrative resources despite having no enrolled students, pointing to gaps in real-time data verification and rationalisation of school infrastructure.

Why: This report is directly relevant to UPSC GS-II (Education, Government Policy) and state PSC exams. Questions on the Right to Education (RTE) Act, school infrastructure rationalisation, and NITI Aayog’s advisory role are common. The ghost school data is also a lens for understanding challenges in implementing Samagra Shiksha Abhiyan.

What: DRDO (Defence Research and Development Organisation) inaugurated a Chemical, Biological, Radiological, and Nuclear (CBRN) Field Training Centre at Burari Plains, New Delhi. The centre functions under the Institute of Nuclear Medicine and Allied Sciences (INMAS), a premier DRDO laboratory, and is part of the DRDO-CBRN Centre of Excellence (CoE).

How: The centre is designed to train armed forces personnel, civil defence responders, and first responders in detection, protection, and decontamination procedures for CBRN threats. By situating the CoE under INMAS — which specialises in nuclear medicine and radiation safety — DRDO ensures that training is grounded in the latest scientific research on radiation biology and hazardous material management.

Why: CBRN preparedness is a growing area of focus in India’s national security doctrine, especially relevant in the context of non-traditional security threats. UPSC Prelims and Mains (GS-III: Internal Security) often test knowledge of DRDO establishments, full forms of defence acronyms, and India’s capabilities in non-conventional threat response. The location (Burari Plains, Delhi) and parent institute (INMAS) are high-value recall facts.

What: Indian space-tech startup Pixxel secured a contract from the United States’ National Reconnaissance Office (NRO) under the Commercial Systems Program Office (CSPO) for its Firefly constellation — a cluster of 6 hyperspectral satellites launched in 2025. Hyperspectral Imaging (HSI) captures data across hundreds of narrow spectral bands, enabling detailed analysis far beyond what standard satellite cameras can detect.

How: Unlike conventional multispectral sensors, Hyperspectral Imaging can identify specific materials, chemicals, and vegetation types by their unique spectral “signatures.” The Firefly constellation’s HSI capability makes it useful for intelligence gathering, environmental monitoring, agricultural assessment, and mineral exploration. The NRO contract validates the commercial and strategic value of Pixxel’s technology on the global stage.

Why: This is a landmark moment for India’s private space sector and a signal of India’s growing space diplomacy with the US. For UPSC Science & Technology (GS-III) and state exams, questions on India’s private space startups, the role of IN-SPACe in enabling them, and dual-use satellite technologies are increasingly common. Key terms to remember: Firefly constellation, Hyperspectral Imaging (HSI), NRO, and CSPO.
