SPACE, SECURITY, ENERGY

SUMMARY

A) SPACE: From Program Milestones to National Infrastructure

  • Space has evolved from prestige science to national infrastructure.
  • ISRO missions now serve governance, economy, and strategic autonomy.
  • SpaDeX (2025) demonstrated autonomous docking capability.
  • NaVIC & NVS-02 strengthened navigation sovereignty.
  • NISAR mission enhances all-weather Earth observation.
  • Institutional ecosystem: VSSC, URSC, SDSC-SHAR, LPSC, SAC, NRSC.
  • Space now underpins disaster management, agriculture, defence, and planning.
  • Space = development + sovereignty + strategic depth.

B) India’s Space Timeline: A Civilisational Arc

  • 1962: INCOSPAR formation; TERLS established.
  • 1975: Aryabhata – first satellite.
  • Evolution of launch vehicles: SLV → ASLV → PSLV → GSLV → LVM3.
  • Satellite applications: communication, remote sensing, meteorology.
  • Exploration: Chandrayaan, solar missions.
  • Future: Gaganyaan & space station ambitions.
  • Lesson: capability builds sequentially.
  • Space journey reflects governance continuity and sovereignty.

C) Planned Missions and Space Policy

  • Upcoming missions: Mangalyaan-2, Shukrayaan-1, Chandrayaan-4, AstroSat-2.
  • Proposal: Bharatiya Antariksha Station (2035).
  • Moon mission goal by 2040.
  • Policy shift: private participation enabled.
  • Institutions: IN-SPACe, NSIL.
  • Exploration + developmental applications.
  • Space framed as infrastructure + soft power.
  • Governance shift toward sustained space architecture.

D) Launch Vehicles and Crew Systems

  • SSLV: responsive, low-cost small satellite launcher.
  • PSLV: reliable workhorse.
  • GSLV & LVM3: heavy-lift capability.
  • Crew Escape System (CES) ensures human mission safety.
  • Reusable Launch Vehicle (RLV-TD) for cost reduction.
  • Scramjet propulsion experiments.
  • Launch autonomy = strategic autonomy.
  • Rockets define economic & exploration capacity.

E) NISAR: Indo–US Collaboration

  • Joint mission of ISRO & NASA.
  • Dual-frequency SAR (L-band & S-band).
  • All-weather, day-night imaging.
  • Monitors land deformation, glaciers, crops.
  • Disaster & climate governance tool.
  • Strategic relevance for terrain monitoring.
  • Represents operational Earth observation maturity.
  • Civil + strategic convergence.

F) Defence Modernisation

  • Focus on indigenisation (Atmanirbhar Bharat).
  • Increased defence capital expenditure.
  • Theatre command reforms.
  • Institutions: SFC, DCA, DSA, IDS.
  • Adoption of AI, robotics, hypersonics.
  • Defence exports rising.
  • Multi-domain warfare approach.
  • Technology-driven deterrence.

G) Services and Force Structure

  • Army: 7 operational commands.
  • Air Force: 5 operational + functional commands.
  • Navy: Western, Eastern, Southern commands.
  • Coast Guard complements maritime security.
  • Agnipath scheme reforms manpower.
  • Rank equivalence promotes jointness.
  • Structured hierarchy ensures clarity.
  • Integration toward theatre commands.

H) Operation Sindoor: Multi-Domain Warfare

  • Trigger: April 2025 terror attack.
  • Calibrated precision response.
  • Integrated Air Command & Control System (IACCS).
  • Use of precision strikes & loitering munitions.
  • Drone and counter-drone systems.
  • Defence Communication Network (DCN).
  • Satellite-based surveillance.
  • Shift from platform-centric to ecosystem-centric warfare.

I) Internal Security and Policing

  • Multi-vector threats: terrorism, narcotics, cybercrime.
  • Police = State subject; Centre-State coordination essential.
  • CAPFs: BSF, CRPF, CISF, ITBP, SSB, NSG, Assam Rifles.
  • Cyber hygiene & digital threat mitigation.
  • National Security Council system.
  • SPG for PM security.
  • Data security = new frontline.
  • Internal security = layered governance model.

J) Nuclear Program and Deterrence

  • Doctrine: No First Use (NFU).
  • Credible minimum deterrence.
  • Nuclear Command Authority (NCA).
  • Strategic Forces Command (SFC).
  • Nuclear triad (land, air, sea).
  • 2008 IAEA safeguards & NSG waiver.
  • Membership in MTCR, Wassenaar, Australia Group.
  • Deterrence + global regime engagement.

K) Energy Sector: Reserves & Geography

  • Coal reserves ~389.42 billion tonnes.
  • Lignite re
