Designated Repository
Context: The Natural History Museum (NHM) at Mizoram University, Aizawl, was officially notified by the Ministry of Environment, Forest and Climate Change (MoEFCC) as India’s 21st Designated Repository.
About Natural History Museum (NHM) Mizoram
- Natural History Museum (NHM) was established in 2022 under the aegis of Mizoram University, a Central University established by an Act of Parliament.
- The NHM is uniquely positioned because of its location within the Indo-Burma Biodiversity Hotspot and its specialised taxonomic expertise.

About Designated Repository
- A Designated Repository is a notified institution under Section 39 of the Biological Diversity Act, 2002, authorised to preserve authenticated biological specimens accessed under the Act.
- Key Features
- Legal Status: Designated Repositories are notified by the Central Government on the recommendation of the National Biodiversity Authority (NBA).
- Specimen Preservation: They preserve voucher specimens and type specimens of plants, animals, fungi and other biological resources for scientific authentication and long-term conservation.
- Scientific Documentation: They strengthen species identification, taxonomic research, traceability and biodiversity documentation, while supporting ecological restoration and conservation planning.
- Regional Representation: Repositories complement institutions such as the Botanical Survey of India (BSI) and Zoological Survey of India (ZSI) by preserving region-specific biological diversity closer to its source.
- Significance
- Strengthening Ex-situ Conservation: Designated Repositories preserve authenticated biological specimens and genetic resources, advancing National Biodiversity Strategy and Action Plan (2024–2030) and Target 4 of the Kunming–Montreal Global Biodiversity Framework.
- Conserving Biodiversity Hotspots: The designation of Mizoram University’s Natural History Museum, located in the Indo-Burma Biodiversity Hotspot, strengthens conservation, scientific research and documentation of endemic and newly discovered species in Northeast India.
Earth’s Vegetative Biosphere Life
Context: A new climate study estimates that Earth’s vegetative biosphere may survive for about 1.87 billion more years before rising solar heat ends photosynthetic life.
Key Findings of the Study
- Advanced Climate Modelling: Researchers used a sophisticated climate model incorporating clouds, humidity, atmospheric circulation and weathering processes, providing more accurate estimates than earlier studies.
- Future of Land Plants: Under the weak weathering scenario, land plants may survive for about 1.68 billion years, after which rising temperatures will exceed their thermal tolerance.
- End of the Vegetative Biosphere: Around 1.87 billion years from now, Earth’s climate is expected to become too hot for all land plants, marking the extinction of the vegetative biosphere.
- Long-Term Planetary Changes: The study estimates that by 2.1 billion years, Earth may begin losing its oceans to space as the aging Sun becomes hotter and more luminous.
About Vegetative Biosphere
- The vegetative biosphere is the global sum of all plants, algae and photosynthetic organisms, forming the primary producer component of Earth’s biosphere.
- Origin: It originated about 3.5 billion years ago with photosynthetic cyanobacteria, whose oxygen-producing activity triggered the Great Oxidation Event, enabling the evolution of complex life.
- Key Features
-
- Primary Producer: It converts solar energy into chemical energy through photosynthesis, forming the foundation of terrestrial and marine food webs.
- Climate Regulator: Vegetation acts as a major carbon sink, absorbing atmospheric carbon dioxide and helping regulate Earth’s climate.
- Oxygen Generator: Plants, marine algae and phytoplankton produce most of the oxygen required for aerobic life on Earth.
- Ecosystem Support: Vegetation conserves soil, reduces erosion, regulates the water cycle, and sustains biodiversity by providing food and habitat for diverse organisms.
Mission Drishti
Context: Mission Drishti, India’s first private OptoSAR satellite, lost communication following a geomagnetic solar storm during its Launch and Early Orbit Phase (LEOP).
About Mission Drishti
- Mission Drishti is the world’s first commercial OptoSAR Earth Observation satellite, integrating optical and radar imaging on a single platform for continuous all-weather monitoring.
- Developed By: GalaxEye Space, a Bengaluru-based space-tech startup founded by IIT Madras alumni, and launched aboard SpaceX’s Falcon 9 on 3 May 2026 into a Sun-synchronous Low Earth Orbit (LEO).
- Mission Objective: To provide high-resolution, real-time Earth observation for defence, disaster management, agriculture, environmental monitoring and commercial applications through uninterrupted day-and-night imaging.
- Key Components
-
- OptoSAR Technology: Combines Multispectral Imaging Sensor (MSI) and Synthetic Aperture Radar (SAR) on a single satellite, a global first for commercial Earth observation.
- All-Weather Imaging: SAR enables imaging through clouds, smoke and darkness, while optical sensors provide detailed visual imagery for continuous monitoring.
- SyncFusion Stack: Proprietary onboard technology synchronises and fuses optical and radar data in real time, eliminating extensive post-processing.
- Satellite Specifications: Weighing 190 kg, it is India’s largest privately developed Earth observation satellite, offering 1.5–1.8 metre spatial resolution.
Recent Developments
- Solar Storm Anomaly: During the final stage of LEOP, an extreme geomagnetic solar storm caused radiation-induced damage to a critical onboard system, leading to intermittent and eventually lost communication.
- Mission Achievements: Despite the anomaly, the mission successfully validated core OptoSAR technologies, mission operations and data-fusion capabilities, providing valuable engineering insights for future missions.

Future Roadmap
- GalaxEye plans to launch two next-generation OptoSAR satellites within the next 24 months, while expanding indigenous manufacturing and satellite development under Atmanirbhar Bharat and IN-SPACe initiatives.

About BRICS Guwahati Declaration
- The Guwahati Declaration was adopted at the BRICS Heads of Anti-Drug Agencies Meeting 2026 held in Guwahati, Assam, under India’s BRICS Chairship.
- Adopted by : 11 BRICS member countries to enhance cooperation against illicit drug trafficking, synthetic drugs, precursor chemicals, and transnational organised crime.
- Key Components
-
- Strengthens intelligence sharing, timely exchange of information, best practices, and operational cooperation among BRICS anti-drug agencies.
- Promotes innovative technologies, digital tools, AI and data-driven approaches to improve law enforcement and regulatory mechanisms against drug trafficking.
- Addresses emerging threats, including synthetic drugs, new psychoactive substances (NPS), diversion of precursor chemicals, virtual assets, digital platforms, and misuse of maritime routes by criminal networks.
- Emphasises demand reduction through awareness campaigns, healthy lifestyles, evidence-based prevention, treatment, de-addiction, and rehabilitation, particularly for children and youth.
- Encourages capacity building, including virtual workshops, cross-border training, and a network-centric approach to dismantle transnational drug syndicates.
- Significance: The declaration reinforces collective BRICS action against transnational drug networks, enhancing global security, public health, and law enforcement cooperation.
