World Geography | Central Asia | India-Uzbekistan relations

WHY IN NEWS:

India and Uzbekistan agreed to deepen their strategic partnership in critical minerals, mining, trade, energy and defence during high-level bilateral talks in New Delhi.

IN ONE LINE: Uzbekistan is a doubly landlocked Central Asian country located between the Amu Darya and Syr Darya rivers, with Tashkent as its capital.

Basic profile

• Official name: Republic of Uzbekistan.

• It was part of the Soviet Union and became independent in 1991.

• It is known for its Silk Road heritage, Islamic architecture and rich mineral resources.

Location and neighbours

• It lies in the heart of Central Asia, between the Amu Darya and Syr Darya rivers.

• It is doubly landlocked: both Uzbekistan and all the countries directly surrounding it are landlocked.

• Bordering countries: Kazakhstan, Kyrgyzstan, Tajikistan, Afghanistan and Turkmenistan.

• Capital: Tashkent, also written as Toshkent.

Major physical features

• Kyzylkum Desert: Covers much of western Uzbekistan, forms part of the Turan Plain and is one of Central Asia's largest deserts.

• Ustyurt Plateau: An arid limestone plateau in western Karakalpakstan, marked by low ridges, sinkholes, salt marshes and steep escarpments.

• Tien Shan and Gissar ranges: Located in the east and southeast. Beshtor Peak, at 4,299 metres, is the country's highest point.

• Aral Sea Basin: The Aral Sea has lost more than 90% of its volume after diversion of the Amu Darya and Syr Darya. Its dried seabed has formed the Aralkum Desert.

• Fergana and Zeravshan valleys are major agricultural and population centres. Historic cities in these regions include Samarkand, Bukhara and Khiva.

Natural resources

• Uzbekistan has deposits of uranium, gold, copper, molybdenum and rare earth elements.

Cholanaikkan Tribe

Indian Society | Tribes | Particularly Vulnerable Tribal Groups

WHY IN NEWS: Members of the Cholanaikkan tribe recently came out of the forest to receive essential government documents at an event organised by the district administration in Kerala.

IN ONE LINE: The Cholanaikkans are a cave-dwelling PVTG found exclusively in the Nilambur Valley of Kerala within the Nilgiri Biosphere Reserve.

Who are the Cholanaikkans?

• They are an indigenous tribal community found exclusively in the Nilambur Valley of the Nilgiri Biosphere Reserve in Kerala.

• They are popularly called the "Cavemen of Kerala" and are regarded as one of Asia's last surviving cave-dwelling indigenous communities.

Meaning of the name

• The community refers to itself as Malanaikan or Sholanaikan.

• "Shola" or "Chola" means deep forest or thicket, while "Naikan" means king.

Habitat and settlements

• They live deep inside dense forests, usually close to streams and water sources.

• Natural rock caves used as shelters are locally called Kallulai: "Kallu" means rock and "Alai" means cave.

• They do not have permanent dwellings.

Social and cultural profile

• The community is divided into smaller social groups known as Jenmam.

• Their Cholanaikkan language belongs to the Dravidian language family.

• Their livelihood mainly depends on collecting forest produce and other forest-based subsistence activities.

• They are classified as a Particularly Vulnerable Tribal Group (PVTG).

Panari Pumped Storage Project

Energy Infrastructure | Wildlife clearance | Tiger corridors

WHY IN NEWS:

The Standing Committee of the National Board for Wildlife recommended wildlife clearance for the Panari Pumped Storage Project in the Panna-Ranipur Tiger Corridor.

IN ONE LINE: Panari is a proposed 1,800 MW pumped storage project in Madhya Pradesh that will use the Baghain River and provide nine hours of energy storage.

Project profile

• Type: Pumped Storage Project (PSP).

• Location: Satna and Panna districts of Madhya Pradesh.

• Water source: Baghain River.

• The project will generate electricity by recirculating water.

Why pumped storage matters

• Electricity is stored during periods of low demand and generated during peak demand.

• This helps improve grid stability and provides large-scale energy storage.

Capacity at a glance

• Installed capacity: 1,800 MW.

• Energy storage capacity: 16,200 MWh.

• Storage duration: 9 hours.

Baghain River

• The Baghain is a tributary of the Yamuna River.

• It originates in the Vindhyan Hills of Madhya Pradesh.

• It flows through Madhya Pradesh and Uttar Pradesh before joining the Yamuna.

Ecological location

• The project lies within the Panna-Ranipur Tiger Corridor.

• The corridor connects Panna Tiger Reserve in Madhya Pradesh with Ranipur Tiger Reserve in Uttar Pradesh.

Proposed conservation measures

• Wildlife overpasses and underpasses.

• Box culverts and road realignment.

• A Rs 41 crore Wildlife Conservation Plan.

• A Rs 49.95 crore Catchment Area Treatment Plan.

PowerBank-50

Space Technology | Private space sector | Indigenous components

WHY IN NEWS: Hyderabad-based TakeMe2Space announced that PowerBank-50 earned flight heritage after successfully completing its maiden space mission aboard Skyroot Aerospace's Vikram-1.

IN ONE LINE: PowerBank-50 is an indigenous, compact lithium-ion satellite battery pack designed for small satellites and proven to operate successfully in space.

What is PowerBank-50?

• It is an indigenously developed satellite battery pack built by TakeMe2Space, a Hyderabad-based spacetech startup.

• It is India's first indigenously developed satellite battery to receive flight heritage status.

• Its first mission was completed aboard Vikram-1 during Mission Aagaman.

Mission performance

• A PowerBank-50 unit powered Cosmoserve Space's experimental payload on the rocket's Orbital Adjustment Module.

• The mission operated at an altitude of about 450 km.

• The battery worked successfully through launch, vacuum, space radiation and extreme temperature variations.

Key specifications

• Technology: Compact lithium-ion battery pack for small satellites.

• Weight: Approximately 380 grams.

• Size: Roughly equal to a paperback book.

• Energy storage: More than 50 Wh.

• Equipment: Intelligent Battery Management System, onboard heaters and an aluminium flight enclosure.

• Multiple units can be stacked to power CubeSats and microsatellites.

• Operational life: Up to five years in Low Earth Orbit.

What does flight heritage mean?

• Flight heritage is earned after a component has operated successfully in space.

• Launch providers, satellite manufacturers and insurers prefer components with proven in-space performance.

• The status improves the credibility and commercial acceptance of space hardware.

Why are satellite batteries tested so strictly?

• They are safety-critical components and must withstand intense launch vibration and shock.

• They must continue functioning in vacuum, radiation and repeated extreme hot-cold cycles in orbit.

Significance for India

• Demonstrates the capability to develop space-qualified indigenous satellite components.

• Strengthens the domestic ecosystem for CubeSats, microsatellites and commercial missions.

• Supports Aatmanirbhar Bharat in the space sector.

About Vikram-1

• Vikram-1 is a launch vehicle developed by Skyroot Aerospace.
