June-Science & Technology

1: Space Exploration & Human Missions

June 2025 was a historic month for Indian space diplomacy and indigenous capability, centered on the Axiom-4 mission.

1. Axiom-4 Mission (Ax-4) & Shubhanshu Shukla

• The Launch: On June 25, 2025, IAF Group Captain Shubhanshu Shukla (Call sign: Shux) launched to the International Space Station (ISS) aboard a SpaceX Dragon spacecraft.
• Role: He served as the Mission Pilot, flying alongside Commander Peggy Whitson (USA).
• 7 Microgravity Experiments: Shukla successfully completed a suite of experiments developed by Indian institutions (IISc, TIFR, etc.):
  1. Tardigrade Study: Researching the survival of the "Indian strain" of tardigrades in extreme space radiation.
  2. Myogenesis: Studying human muscle stem cell regeneration to combat muscle loss in space.
  3. Space Micro-Algae: Testing micro-algae for potential oxygen and food production.
  4. Cyanobacteria: Investigating their growth as part of future bioregenerative life support systems.
  5. Seed Sprouting: Germinating methi (fenugreek) and moong seeds in zero-G.
  6. Cognitive Assessments: Testing human-machine interface on digital displays in orbit.
  7. Radiation Monitoring: Assessing the effectiveness of shielding materials on the ISS.
• Significance: This mission serves as a critical bridge for India's Gaganyaan program, providing real-time data on astronaut health and life-support systems.

2. Chandrayaan-5 (LUPEX Mission) Technical Freeze

• Context: Following the Cabinet approval in March 2025, ISRO and JAXA (Japan) concluded the Technical Interface Meeting (TIM) in June.
• The Configuration: * Lander: To be built by ISRO.
  • Rover: To be built by JAXA (approx. 350 kg).
• Objective: To explore the "Permanently Shadowed Regions" (PSRs) of the Lunar South Pole for water ice. It will use a 1.5-meter drill to sample subsurface volatiles.

Defence Technology & Indigenous Innovation

1. Hypersonic Milestone: Scramjet Testing

• Achievement: DRDO successfully conducted a 1,000-second ground test of an Active Cooled Scramjet Subscale Combustor in June 2025.
• Significance: Scramjet technology is the "holy grail" of hypersonic flight (Mach 5+). This test proves India’s ability to manage extreme heat during sustained hypersonic speeds, vital for future cruise missiles.

2. Quantum Secure Communication (QKD)

• The Breakthrough: ISRO demonstrated Free-Space Quantum Key Distribution (QKD) over a distance of 1 km via an optical link.
• Impact: This is a major step toward building a "Quantum-proof" communication network for defense and banking, ensuring that data cannot be intercepted or hacked even by future quantum computers.

3. Biotechnology: India's First Gene-Edited Sheep

• News: Researchers from Kashmir University and ICAR produced India’s first gene-edited sheep using CRISPR-Cas9 technology.
• Goal: To improve wool quality and disease resistance, following the successful release of gene-edited rice varieties earlier in the year.

4. Samudrayaan Mission (MATSYA 6000)

• Update: In June 2025, the Ministry of Earth Sciences finalized the "Internal Pressure Hull" tests for MATSYA 6000.
• Mission: Aiming for a 2026 launch, this submersible will carry 3 humans to a depth of 6,000 meters to explore rare minerals (polymetallic nodules) in the Central Indian Ocean.

Emerging Tech & Health Science

• BharatGen Platform: The Ministry of S&T launched BharatGen, India’s first indigenous Generative AI platform, designed to support Indian languages and localized data processing.
• HIV Prevention Milestone: The WHO and Indian regulators reviewed Lenacapavir (a twice-yearly injectable) in June, paving the way for its inclusion in India's National AIDS Control Programme.
• Core-Mantle Connectivity: New geological research published in June revealed active material exchange between Earth's core and mantle, explaining the presence of rare gold deposits in the crust—a topic now added to the Geography/S&T overlap syllabus.

Indigenous Systems & Deep-Tech Breakthroughs

1. Commissioning of INS Arnala (ASW-SWC)

On June 18, 2025, the Indian Navy commissioned INS Arnala, the first of 16 Anti-Submarine Warfare Shallow Water Crafts.

• Strategic Utility: Specifically designed for "littoral" (coastal) waters to detect and engage midget submarines and unmanned underwater vehicles (UUVs).
• Technical First: It is the largest Indian warship to be powered by a diesel engine–waterjet propulsion system, providing high maneuverability in shallow waters (draught of only 2.7 meters).
• Indigenization: Boasts over 80% indigenous content, including the "Abhay" hull-mounted sonar.

2. DRDO’s Mega Technology Transfer (ToT)

In June 2025, DRDO’s Vehicle Research and Development Establishment (VRDE) transferred technologies for 9 critical defense systems to 10 Indian private industries.

• Systems include: * CBRN Recce Vehicle: For detecting chemical, biological, and nuclear threats.
  • Vajra-Riot Control Vehicle: Upgraded with advanced non-lethal deterrents.
  • Mounted Gun Systems: Enhancing the mobility of artillery.
• Context: This is part of the "Operation Sindoor" performance review, where indigenous systems proved superior to imported ones in desert trials.

3. Biotechnology: The National Biofoundry Network

The Department of Biotechnology (DBT) launched India's first National Biofoundry Network in June 2025 under the BioE3 Policy.

• What is it? A network of 6 specialized hubs that use AI and Robotics to automate "synthetic biology"—essentially "programming" microbes to produce chemicals, fuels, and medicines.
• Portals Launched: The FeED (Framework for Exchange of Data Protocols) and the Indian Biological Data Centre (IBDC) portals were opened, making 10,000 whole-genome samples available to researchers.

4. AI "Cognitive Debt" Study & BharatGen

A major study published in June 2025 (collaboration between MIT and Indian researchers) introduced the term "Cognitive Debt".

• Findings: Users who over-rely on LLMs (like ChatGPT) showed a 55% reduction in brain connectivity related to critical thinking over four months.
• India’s Response: The government fast-tracked the BharatGen initiative (IIT Bombay-led) to create a multimodal LLM that focuses on "Pedagogical AI"—AI that guides students to answers rather than just giving them, to prevent this cognitive decline.
