Science and Technology (December 2025)

1. ​LVM3-M6 / BlueBird Block-2 Mission

​On December 24, 2025, ISRO successfully launched the BlueBird Block-2 satellite using its heaviest launcher, the LVM3.

• ​Record Payload: At 6,100 kg, it is the heaviest foreign payload ever launched from Indian soil.
• ​Technological Shift: Developed by AST SpaceMobile (USA), these satellites enable direct-to-smartphone connectivity, allowing standard 4G/5G phones to connect via satellite without specialized hardware.
• ​Commercial Dimension: Executed by NewSpace India Limited (NSIL), this mission solidifies LVM3’s position as a reliable heavy-lift vehicle in the global commercial market.

​Gaganyaan: The G1 Uncrewed Mission

• ​Vyommitra: ISRO finalized the deployment of Vyommitra, the AI-enabled half-humanoid robot, for the G1 uncrewed test flight scheduled for late December 2025.
• ​Purpose: Vyommitra will simulate human functions, monitoring life support, avionics, and environmental control systems to ensure the crew module is safe for future Indian astronauts.
• ​Testing Phase: ISRO Chairman V. Narayanan confirmed that over 85% of the required tests (including parachute and cryogenic engine trials) were completed by the end of the month.

2. Information Technology & Semiconductors

​DHRUV64 Indigenous Microprocessor

​Launched on December 15, 2025, this marks a significant leap in India's semiconductor sovereignty.

• ​Specifications: A 64-bit, 1.0 GHz dual-core processor designed by C-DAC under the Digital India RISC-V (DIR-V) program.
• ​Strategic Significance: It reduces reliance on foreign proprietary architectures (like ARM or Intel). It is specifically designed for 5G telecom, industrial automation, and IoT (Internet of Things).
• ​Cybersecurity: Having a domestic "root of trust" in the processor design is vital for secure communications and defense hardware.

​India AI Governance Guidelines

​The Ministry of Electronics and IT (MeitY) unveiled a "light-touch" regulatory framework for Artificial Intelligence.

• ​Core Principle: Prioritizes responsible innovation over restrictive mandates.
• ​The Seven Sutras: Trust, People First, Innovation, Fairness, Accountability, Understandability, and Safety.
• ​Deepfake Regulation: Mandates that intermediaries remove flagged AI-misinformation within hours and implement clear watermarking for synthetic content.

​3. Biotechnology & Health

​BioE3 Policy Implementation

​The Union Cabinet formally approved and began the rollout of the BioE3 Policy (Biotechnology for Economy, Environment, and Employment).

• ​Objective: To foster "High-Performance Biomanufacturing" and push India’s bio-economy toward a $300 billion target by 2030.
• ​Biofoundries: The government initiated the setup of "Bio-Enablers" (Biofoundries and Biomanufacturing Hubs) to support startups in creating bio-based chemicals, smart proteins, and biopolymers.

​Urban Malaria Concern: Anopheles stephensi

​Health reports in December highlighted the rising threat of this specific mosquito vector.

• ​The Challenge: Unlike rural vectors, Anopheles stephensi adapts exceptionally well to urban containers (tanks, AC ducts). It has developed resistance to common insecticides, complicating India's goal of being Malaria-free by 2030.

​4. Quantum & Nuclear Science

​National Quantum Mission (NQM) Progress

• ​Four Thematic Hubs: By December, the four T-Hubs (Computing, Communication, Sensing, and Materials) became fully operational at IISc Bengaluru, IIT Madras, IIT Bombay, and IIT Delhi.
• ​Milestone: A 500 km secure quantum communication link was successfully demonstrated, a critical step toward a "Quantum-proof" national internet.

​The SHANTI Act

• ​Nuclear Liberalization: This legislative initiative aims to allow greater private sector participation in India's nuclear energy sector.
• ​Goal: To accelerate the deployment of Small Modular Reactors (SMRs) to meet India’s Net-Zero commitments.
