Sri Aurobindo’s Birth Anniversary
Context: Prime Minister Narendra Modi paid tribute to Sri Aurobindo on his birth anniversary on 15 August 2026, recalling his contribution to India’s freedom struggle, philosophy and human progress.
About Sri Aurobindo
- Sri Aurobindo Ghose (1872–1950) was a philosopher, nationalist, poet and spiritual thinker who played an important role in India’s freedom movement.
- Born in Calcutta on 15 August 1872, he was educated in England at St. Paul’s School, London, and King’s College, Cambridge.
- After returning to India in 1893, he served in Baroda State and worked as a professor at Baroda College.
- Following the Partition of Bengal in 1905, he moved to Calcutta in 1906 and became a prominent nationalist leader.
- Through Bande Mataram and other writings, he advocated complete independence from British rule.
- He was imprisoned during the Alipore Bomb Case in 1908 but was released for lack of evidence.
Legacy of Sri Aurobindo
- Sri Aurobindo gradually shifted from active politics towards spirituality.
- In 1910, he moved to Pondicherry and devoted himself to spiritual practice, developing the philosophy of Integral Yoga, which sought not merely individual liberation but the transformation of human consciousness and nature.
- In 1926, he founded the Sri Aurobindo Ashram with his spiritual collaborator, Mirra Alfassa, known as “The Mother”.
- His major works include The Life Divine, The Synthesis of Yoga, Savitri, Essays on the Gita and The Human Cycle.
- His ideas on nationalism, spirituality, human evolution and transformation continue to influence intellectual and spiritual thought worldwide.
Voyager 2 Mission
Context: NASA has implemented a power-saving modification on Voyager 2, allowing its scientific mission to continue for at least another year despite the spacecraft’s declining power supply.
More on the News
- Power-saving upgrade: NASA engineers carried out a modification that reduces Voyager 2’s power consumption while keeping its key scientific operations running.
- Science instruments preserved: The intervention allows three instruments — Cosmic Ray Subsystem, Magnetometer and Plasma Wave Subsystem — to continue collecting data.
- Why needed: Voyager 2’s radioisotope thermoelectric generator (RTG) gradually produces less electricity as its plutonium fuel decays. NASA has therefore been progressively switching off non-essential systems.
- Mission extension: The modification is expected to provide at least one additional year of science operations, extending the spacecraft’s ability to study the interstellar environment.
About Voyager 2
- Launch: Voyager 2 was launched on 20 August 1977 and conducted flybys of Jupiter, Saturn, Uranus and Neptune.
- Unique achievement: It remains the only spacecraft to have visited Uranus and Neptune.
- Interstellar mission: Voyager 2 crossed the heliopause in November 2018 and entered interstellar space.
- Power source: It uses an RTG, which generates electricity from the heat released by radioactive decay.
Significance of Voyager 2
- Outer Solar System: It provided humanity’s only close-up observations of Uranus and Neptune, transforming understanding of these ice giants.
- Interstellar science: Its instruments provide direct measurements of magnetic fields, charged particles and plasma waves beyond the heliosphere.
- Scientific legacy: Continued observations from beyond the heliopause provide a rare opportunity to study the boundary between the Sun’s influence and the interstellar medium.

New Security Rules for Renewable Energy Projects Near Borders
Context: The Ministry of Home Affairs (MHA) has issued guidelines for national security clearance of solar, wind and hybrid renewable-energy projects in border areas, balancing renewable-energy development with national-security considerations.
Key Highlights of the Guidelines
- 1-km restricted zone: No new solar, wind or hybrid renewable-energy project is permitted within 1 km of the International Border (IB), Line of Control (LoC) or Line of Actual Control (LAC).
- Security-clearance zone: Projects proposed within 1–50 km of the IB, LoC or LAC require MHA security clearance.
- Projects within 1–20 km of the IB additionally require a No-Objection Certificate (NOC) from the Ministry of Defence (MoD).
- Height restrictions: Civil infrastructure for project maintenance and operation is capped at 3 m within 1–8 km, 5 m within 8–20 km and 15 m within 20–50 km of the border.
- Security safeguards: Projects must provide comprehensive security measures, including anti-drone systems, and a dedicated police post for monitoring construction and operations. The project proponent bears the cost of such security equipment.
- Foreign personnel: Engineers, staff, employees and labour from countries sharing a land border with India require Central Government permission for project implementation.
- Application and clearances: Applications are submitted through the Ministry of New and Renewable Energy (MNRE), which coordinates the security-clearance process with MHA and MoD.
Why Are Renewable-Energy Projects Near Borders Sensitive?
- Surveillance and visibility: Large renewable-energy installations, particularly wind turbines and associated infrastructure, can affect the surveillance environment and visibility in strategically sensitive border zones.
- Impact on border operations: Construction, access roads and associated infrastructure may interfere with movement, patrolling and operational requirements of security forces near the border.
- Protection of critical infrastructure: Power-generation and transmission assets located close to sensitive borders can become strategically important infrastructure, requiring enhanced protection against security threats.
Significance of the Guidelines
- Security–energy balance: They seek to balance renewable-energy expansion with national-security requirements.
- Regulatory clarity: Uniform security parameters provide greater predictability for project developers in border regions.
- Integrated planning: The guidelines bring security considerations into renewable-energy and infrastructure planning.

DRI Dismantles Major Areca Nut Import Network Using Fraudulent SAFTA
Context: The Directorate of Revenue Intelligence (DRI) has dismantled a major network involved in importing South-East Asian areca nuts into India by falsely declaring them as Bangladeshi origin and fraudulently availing concessional duty benefits under the South Asian Free Trade Area (SAFTA).
About the South Asian Free Trade Area (SAFTA)
- The South Asian Free Trade Area (SAFTA) is the free trade arrangement of the South Asian Association for Regional Cooperation (SAARC).
- The agreement came into force in 2006, succeeding the 1993 SAARC Preferential Trading Arrangement.
- SAFTA signatory countries are Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka.
- SAFTA recognizes the need for special and differential treatment for Least Developed Countries (LDCs) in its preamble.
- LDCs benefit from smaller sensitive lists in some of the SAFTA members and less stringent rules of origin.
- LDCs were allowed smaller initial tariff reductions and longer implementation periods under trade liberalization programmes.
About the Areca Nut
- Areca nut is the fruit of the Areca catechu palm tree, mainly grown in South-East Asia and Pacific islands.
- It is chewed in various forms, including plain supari, sweet supari, pan masala and gutkha.
- The International Agency for Research on Cancer (IARC) in 2004 classified areca nut as a Group I carcinogen, and its consumption is associated with oral submucous fibrosis and oral cancer.
