Lagrange Points & Aditya-L1 Mission About Lagrange Points Lagrange Points are positions in space where the gravitational forces of two large celestial bodies (like the Sun and Earth) and the centrifugal force of a smaller object (like a satellite) balance out. An object placed at a Lagrange Point remains relatively stable and can orbit with minimal fuel use. These points are named after Joseph-Louis Lagrange, an 18th-century mathematician. The Five Lagrange Points (L1 to L5) L1: Between Earth and the Sun. Ideal for continuous solar observation. L2: Beyond Earth, away from the Sun. Used for deep space telescopes like James Webb. L3: Behind the Sun, opposite Earth’s orbit (not practically useful). L4 & L5: Located at Earth’s orbit forming an equilateral triangle with the Sun and Earth. Stable but far from Earth. Key Institutional Reference – ISRO’s Aditya-L1 Mission Aditya-L1 is India’s first dedicated solar mission developed by ISRO. Launched to Lagrange Point 1 (L1), about 1.5 million km from Earth. Objective: Observe the Sun continuously without any eclipses or atmospheric interference. Objectives of Aditya-L1 Mission To study the solar corona, which is the outermost layer of the Sun’s atmosphere. Monitor solar flares, coronal mass ejections (CMEs), and their impact on Earth’s magnetic field. Understand space weather, which can disrupt satellites, GPS, power grids, and communication networks. Investigate the physics of the solar atmosphere and the dynamics of the Sun's magnetic field. Key Payloads of Aditya-L1 Visible Emission Line Coronagraph (VELC): Studies the solar corona. Solar Ultraviolet Imaging Telescope (SUIT): Observes Sun in UV spectrum. Aditya Solar wind Particle Experiment (ASPEX): Measures solar wind properties.

Mangroves & Coastal Security: Ecological Importance and Conservation Efforts Why it’s in the News:Increasing climate threats and rising sea levels have brought renewed focus on the role of mangroves in coastal protection and ecological balance. Key Points: Mangrove Ecosystems: Salt-tolerant trees/shrubs thriving in intertidal zones, unique for their aerial roots (pneumatophores) and vivipary (seed germination on parent plant). Ecological Significance: Act as natural coastal buffers reducing damage from cyclones, tsunamis, and storm surges. Serve as carbon sinks (blue carbon) sequestering carbon 3–5 times more than terrestrial forests. Provide habitats and nurseries for marine species like fish, crabs, and migratory birds. Support livelihoods for coastal communities via fisheries, honey, and ecotourism. Threats: Rising sea levels, industrial pollution, land conversion for aquaculture and agriculture, invasive species like Prosopis juliflora. Damage from cyclones such as Amphan (2020) and Mocha (2023). Conservation Initiatives: MISHTI (Mangrove Initiative for Shoreline Habitats and Tangible Incomes): Financial assistance and awareness programs by the government. WWF’s Magical Mangroves Campaign and state-level efforts (Tamil Nadu, Gujarat, Maharashtra). CRZ 2019 Notification: Designates mangroves as Ecologically Sensitive Areas with mandatory 50m buffer zones. Use of Remote Sensing & GIS for monitoring and restoration. State-Level Success Stories: Tamil Nadu doubled mangrove cover in key districts. Mumbai’s project combining mangrove restoration with urban cleanup and women’s employment. Gujarat leads in mangrove cover and restoration, aligning with blue carbon goals. 5. Legal Aid Systems in India: Bridging the Justice Gap Why it’s in the News:The India Justice Report 2022–23 highlights major gaps in legal aid delivery despite constitutional guarantees under Articles 21 and 39A. Key Points: Legal Framework: Legal Services Authorities Act, 1987 establishes free legal aid nationwide. Institutions: NALSA (National Legal Services Authority) — central coordination. SLSAs & DLSAs — state and district level legal services. Legal Aid Clinics: Only one clinic per 163 villages, insufficient for the huge demand. Coverage: About 80% of India’s population is eligible, but only 15.5 lakh beneficiaries received aid in 2023-24. Budget & Resources: Legal aid gets <1% of the total judiciary budget. NALSA fund utilization dropped from 79% to 59% in 5 years. Per capita spending nationally is just ₹3; states like Bihar and Assam lag far behind. Paralegal Volunteers (PLVs): Serve as grassroots legal educators and mediators. Active deployment dropped drastically from 53,000 trained to 14,000 active PLVs in 2023. Honorariums are often below minimum wage; Kerala is an exception. Legal Aid Defense Counsel (LADC) Scheme: Modeled on public defender systems internationally. Operational in 610 of 670 districts but funding was cut in 2024–25. Challenges: Limited awareness among eligible populations. Quality and accountability issues. Geographic, linguistic, and socioeconomic barriers. Factual References: India Justice Report (2022-23) by Tata Trusts & Daksh NALSA Annual Reports Ministry of Law & Justice Budget Documents 6. Police Reforms in India: Challenges Why it’s in the News:Despite landmark Supreme Court directives in Prakash Singh vs. Union of India (2006), police reforms remain incomplete, impacting accountability and law enforcement efficacy. Key Points: Supreme Court Directives: Establish State Security Commissions (SSC) to insulate police from political interference. Merit-based appointment and minimum two-year tenure for DGPs. Fixed tenure for operational officers (SPs and SHOs) to prevent arbitrary transfers. Separate investigation wings from law and order duties for professionalism. Constitute Police Establishment Boards for postings and transfers below DSP level. Set up Police Complaints Authorities (PCA) at state and district levels. National Security Commission (NSC) at the center for CPO chiefs’ selection and tenure. Current Status: Many states have not fully implemented SSCs, PCAs, or ensured fixed tenures. Political interference and arbitrary transfers persist. Investigation wings are often understaffed and under-resourced. Challenges: Resistance from police leadership and politicians. Lack of accountability mechanisms and public trust. Insufficient training on human rights and community policing. Poor infrastructure and outdated technology in many forces.
