ISRO Successfully Completes Gaganyaan Crew–Service Module Separation Tests

What’s the News?

• The Indian Space Research Organisation (ISRO) has successfully completed a series of Crew Module (CM)–Service Module (SM) separation tests under the Gaganyaan Programme.
• The tests were conducted at the Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, Kerala.
• They validated a critical separation mechanism ahead of Gaganyaan’s first uncrewed mission (G1), targeted for launch in 2026.

Gaganyaan Orbital Module?

• The Orbital Module comprises two major components:
  • Crew Module (CM): A habitable, pressurised capsule designed to accommodate astronauts and safely return them to Earth.
  • Service Module (SM): Provides essential support functions, including propulsion, power and other spacecraft services.
• Both modules remain connected during launch and orbital operations through a separation system and electrical and fluid umbilical connections.
• Before atmospheric re-entry, the Crew Module separates from the Service Module using precisely sequenced pyrotechnic devices and jettisoning mechanisms.

Highlights of the Separation Tests

• Test Setup: A specially instrumented facility at VSSC simulated the integrated CM–SM assembly and separation sequence.
• Major Validations:
  • Successful severing of electrical and fluid umbilical connections.
  • Structural reliability and shock-survivability of critical Crew Module subsystems.
• Systems Evaluated:
  • Avionics and Inertial Navigation Systems.
  • Thermal Protection System (TPS) in the aft and conical heat shields.
  • Crew Module Deployable Umbilical Shield.
  • Pyrotechnic devices associated with the Crew Module Uprighting System and Thermal & Humidity Control System.
• Significance: The tests strengthened confidence in the separation system required for safe Crew Module re-entry during the upcoming G1 mission.

• It identifies three major priorities:
  • Housing as a Human Right: Recognising adequate and affordable housing as essential for a dignified standard of living.
  • Inclusive Policymaking: Involving people experiencing poverty in designing, implementing and evaluating housing policies.
  • Resource Mobilisation: Strengthening public financing and investments to ensure safe, accessible and affordable homes.
• The theme aligns with the Doha Political Declaration, adopted at the Second World Summit for Social Development in 2025.

China Proposes Export Controls on 40 Advanced AI, Solar and Biotechnology Technologies

What’s the News?

• China's Ministry of Commerce and Ministry of Science and Technology have jointly proposed new export controls on 40 advanced technologies across Artificial Intelligence (AI), biotechnology and solar energy.
• The draft revision to China's Catalogue of Technologies Prohibited and Restricted from Export proposes:
  • 14 technologies: Complete export prohibition.
  • 26 technologies: Export restrictions.
• The move aims to safeguard national security, prevent technological misuse and regulate the overseas transfer of sensitive technologies.

Technologies Covered?

The proposed controls cover three major sectors:

• Artificial Intelligence (AI) – 23 Technologies:
  • Includes large AI models, intelligent agents, computing clusters and information-processing technologies.
  • Proposes banning technologies capable of generating or modifying malicious computer code.
  • Covers selected AI-assisted cybersecurity technologies and models trained on sensitive Chinese data.
• Solar Energy (Photovoltaics) – 12 Technologies:
  • Covers polysilicon production, silicon wafer manufacturing and advanced solar-cell manufacturing.
  • Proposes banning selected perovskite and tandem solar-cell module manufacturing technologies.
  • Proposes restrictions on polysilicon engineering technologies for production lines with an annual capacity of 30,000 tonnes or more.
• Biotechnology – 5 Technologies:
  • Covers cell and gene therapy platforms, small nucleic-acid medicines and pathogen-related technologies.

Export Control Framework?

• Pre-Export Registration: Exporters must temporarily register overseas transfers involving listed technologies, including ongoing transactions.
• Technology Transfers: Controls extend to intellectual property transfers, overseas licensing and changes in foreign ownership or control.
• Exemptions: Technologies already publicly available through open-source platforms or academic publications are generally excluded.
• Public Consultation: The draft remains open for public feedback until November 2026, before finalisation.

Additional Info

• Export Controls:
  • Government regulations restricting or prohibiting the transfer of specified goods, software or technologies to foreign recipients.
  • Used for national security, strategic technology protection and preventing potential misuse.
• Significance for India:
  • Proposed solar technology restrictions could affect Indian manufacturers seeking advanced Chinese production technologies.
  • Highlight the importance of domestic manufacturing under the Production Linked Incentive (PLI) Scheme for High Efficiency Solar PV Modules.
  • Reinforce the relevance of indigenous technological capabilities under the IndiaAI Mission.
• Important Distinction:
  • The proposed controls primarily concern specified technologies and associated transfers, rather than a blanket ban on exports of finished solar panels or AI services.

Scientists Identify Over 10,000 Faults on the Shrinking Moon

What’s the News?

• A new study published in The Planetary Science Journal has identified over 10,000 geologically young faults across the Moon's surface.
• The research was led by Thomas R. Watters, scientist emeritus at the Smithsonian's National Air and Space Museum, USA.
• Using images from NASA's Lunar Reconnaissance Orbiter Camera (LROC), scientists estimated that the Moon's radius has decreased by approximately 45 metres over the past 400–800 million years.
• The findings highlight potential moonquake risks for future lunar exploration missions, including NASA's Artemis programme.

Findings of the Study?

• Lunar Contraction:
  • The Moon is gradually shrinking as its interior cools and contracts.
  • Estimated contraction rate: 6–11 centimetres per million years, assuming a constant rate.
  • This contraction creates compressional stress, resulting in faults and surface deformation.
• Fault Distribution:
  • More than 8,900 lobate scarps and 2,000 small mare ridges were mapped.
  • Faults occur across both lunar highlands and maria.
  • Regions with thicker lunar crust generally have fewer faults, suggesting greater geological stability.
• Moonquake Risk:
  • Movement along existing faults or formation of new faults can generate moonquakes.
  • Unlike Earth, where about 90% of seismic activity is concentrated near tectonic plate boundaries, the Moon has a single-plate outer shell.
  • Consequently, moonquakes can occur across different regions of the lunar surface.

What Are Lobate Scarps and Mare Ridges?

• Lobate Scarps:
  • Curved, cliff-like formations produced by thrust faulting.
  • Form when compressional forces push one section of the lunar crust over another.
• Mare Ridges:
  • Raised geological structures found on the Moon's dark basaltic plains, known as lunar maria.
  • Form due to compressional deformation of the lunar crust.
• Both features provide evidence of the Moon's relatively recent tectonic activity.

Implications for Future Lunar Missions?

• Fault-related moonquakes may threaten astronauts, landing systems and permanent lunar infrastructure.
• Seismic risk assessment is important when selecting landing sites for NASA's Artemis programme and other lunar missions.
• Regions with fewer faults and thicker crust may offer comparatively stable locations for future lunar bases.

Additional Info

• Lunar Reconnaissance Orbiter (LRO):
  • Space agency: NASA (USA).
  • Launched: 2009.
  • Objective: Mapping the lunar surface, studying lunar geology and supporting future exploration missions.
  • Its LROC instrument has captured millions of high-resolution lunar images.
• Thrust Fault:
  • A reverse fault formed under compressional stress, where one rock block moves upward over another along a low-angle fault plane.
• Related Indian Mission:
  • Chandrayaan-3: Successfully soft-landed near the lunar south polar region in 2023.
  • Its Instrument for Lunar Seismic Activity (ILSA) measured vibrations and seismic events on the lunar surface.
