Over 4,600 Objects Placed in Orbit in 2025 After 315 Space Launches: ISSAR Report

The Indian Space Situational Assessment Report (ISSAR) by ISRO’s IS4OM provides a comprehensive audit of the orbital environment. In 2025, a record 315 successful launches deployed 4,651 objects into orbit, driven largely by commercial mega-constellations (Starlink, Kuiper). While 1,911 objects re-entered, the net annual growth of space objects reached 74.5%.

The Indian Scenario

Asset Breakdown India maintains 86 satellites in orbit, but only 27 are operational. The remaining consist of 23 defunct satellites and 36 decayed objects. PSLV remains the workhorse (42 rocket bodies in orbit), while the newer LVM-3 has only 3 bodies — reflecting modern debris-reduction efforts.
Space Situational Awareness in Action ISRO performed 18 Collision Avoidance Manoeuvres (CAMs) (14 in LEO, 4 in GEO). A total of 1,082 orbital manoeuvres were executed to maintain satellite health. IRNSS-1D was responsibly decommissioned to a “graveyard orbit” 600 km above GEO.

🇮🇳 Strategic Significance for India

  • Project NETRA: Network for space object Tracking and Analysis — India’s early warning system to protect satellites from debris
  • Space Diplomacy: India chairs the UN working group on Long-term Sustainability (LTS) of Outer Space Activities
  • Debris Free Space Mission (DFSM) 2030: Progress toward zero-debris launches using the POEM platform and de-orbiting technologies
  • IN-SPACe: As India opens space to private players (NGEs), maintaining a clean orbital environment is critical for commercial success

Challenges

Kessler Syndrome: The 74.5% net growth brings us closer to a cascading collision scenario making orbits unusable. Resource Intensity: 1,000+ annual manoeuvres require significant fuel and ground station coordination, shortening satellite lifespan. Solar Cycle 25: Intense solar activity accelerated orbital decay and re-entry frequency.

Conclusion: The ISSAR 2025 report is a call to action for global space governance. India is transitioning from a “launch provider” to a “custodian of the space environment.” To ensure the Final Frontier remains a global common, India must continue leading through transparent reporting and technological innovations in debris mitigation.

Biotech’s Role in Sustainable Agriculture

“Green Biotechnology” involves using scientific techniques like genetic engineering, molecular markers, and tissue culture to modify living organisms for better productivity. In the era of Industry 5.0, the focus has shifted from mass production to human-centric, sustainable, and resilient innovation.

1. Responding to Climate Change Developing abiotic stress-tolerant crops (surviving extreme heat, drought, salinity) and “Carbon-Smart” crops that trap more atmospheric CO₂ into the soil.
2. Enhancing Crop Productivity & Nutrition Biofortification: Golden Rice (Vitamin A), Dhanashakti pearl millet (Iron). Pest Resistance: Built-in resistance (e.g., Bt Cotton) reduces dependency on chemical pesticides, protecting biodiversity and reducing farmer input costs.
3. Transition to Industry 5.0 Precision Farming: Integrating biotech with AI and IoT for real-time soil health data. Bio-Foundries: The BioE3 Policy (2024) emphasizes “Biomanufacturing & Bio-AI hubs.”

🇮🇳 Government Initiatives

  • BioE3 Policy (2024): Biotechnology for Economy, Environment, and Employment — targets high-performance biomanufacturing and climate-resilient agriculture
  • Biotech-KISAN: Farmer-centric scheme connecting scientists with farmers for biotech solutions
  • Bio-RIDE Scheme: Unified program (₹9,197 crore) supporting biotech R&D and entrepreneurship
  • GEAC: Apex body under MoEFCC regulating commercial release of GM crops in India

Challenges: Biosafety concerns (gene flow to wild relatives), monopoly by large seed corporations threatening “Seed Sovereignty,” and regulatory delays (as with GM Mustard) due to lack of long-term ecological impact data.

Conclusion: Biotechnology is the “force multiplier” required to achieve SDG 2 (Zero Hunger). The future lies in balancing high-tech innovation with traditional farming wisdom, ensuring that the benefits of Industry 5.0 reach the last mile — the marginal farmer.

India Withdraws Bid to Host Climate Summit (COP33) in 2028

India has officially withdrawn its candidacy to host COP33 in 2028. PM Modi had originally proposed hosting during COP28 in Dubai (2023). A formal communication to the UNFCCC on April 2, 2026, cited a “review of commitments for 2028” as the primary reason.

Analysis: Why the Withdrawal?

Geopolitical & Energy Volatility Global conflicts (US-Iran tensions in 2026) have prioritized short-term energy security. Hosting a COP requires leading by example with aggressive green targets — commitments that may conflict with India’s current need for traditional fuels to stabilize the economy.
Logistical & Financial Overlap South Korea is expected to host the G20 Summit in 2028. If India were to also host COP33, the diplomatic and financial strain would be immense.
Shift in NDC Focus India’s updated NDCs (March 2026) are “implementation-focused” rather than “announcement-focused,” signaling a move toward steady domestic progress over high-profile global posturing.

COP Hosting Roadmap (2025–2028)

YearEditionHost CountryStatus
2025COP30Brazil (Belém)Focused on the Amazon & Climate Finance
2026COP31Türkiye & AustraliaShared Presidency: Türkiye hosts; Australia leads negotiations
2027COP32EthiopiaAfrican Group representative
2028COP33TBD (Likely South Korea)India has withdrawn; South Korea is frontrunner

🇮🇳 Strategic Implications

  • Missed Leadership: Critics argue India lost a chance to replicate its G20 Success and demand accountability from developed nations for historical emissions
  • Pragmatic Realism: India avoids the “host’s burden” — pressure to sign onto pledges (Global Cooling Pledge, strict methane curbs) that could hinder industrial growth
  • Viksit Bharat @2047: Climate action is being aligned with the developed-economy goal, ensuring green transitions don’t compromise development

Conclusion: India’s withdrawal reflects a “Pragmatic Green Strategy.” While it steps back from the logistical spotlight, its updated NDCs show continued commitment to the Paris Agreement. The focus has shifted from hosting the conversation to executing the transition. India’s challenge will be maintaining climate negotiation influence without the hosting chair’s leverage.

Indian Scientists Find New Way to Measure Distances in Deep Space

Measuring galactic distances is difficult because the “fog” of the Interstellar Medium (ISM) distorts pulsar signals. The new Indian study (published in the Monthly Notices of Royal Astronomical Society) provides a way to see through this fog by combining Dispersion and Scattering — a “two-soldier approach.”

The Traditional “Single-Soldier” Approach: Dispersion Measure (DM) Low-frequency radio waves from pulsars are slowed down more than high-frequency waves by free electrons in the ISM plasma. By measuring the time delay, scientists calculate the DM — the total number of electrons between Earth and the pulsar. The Flaw: It assumes electrons are spread evenly. Regions like the Gum Nebula have dense “clumps” that make pulsars appear much farther away than they actually are.
The New “Two-Soldier” Approach: Adding Scatter Broadening The ISM plasma is turbulent. Radio waves bounce off irregularities (like light through frosted glass), causing the pulse to “smear” — a phenomenon called scintillation. By combining DM (how many electrons) with Scattering (how turbulent/clumpy they are), the researchers could pinpoint exactly where the clumps are located and correct distance errors.

Significance

ApplicationSignificance
Mapping the Milky WayCreates a 3D map of electron density, crucial for all radio astronomy
Gravitational Wave ResearchPulsar Timing Arrays need exact pulsar distances to detect spacetime “ripples”
Extragalactic PotentialCan be applied to Fast Radio Bursts (FRBs) to map the universe’s “web”
Indigenous CapabilityShowcases depth of IIT-K, RRI, and NCRA in complex astrophysical data analysis

Conclusion: By systematically applying the k-factor (a parameter for scattering variations), Indian researchers have turned a “noise” problem (scattering) into a “signal” solution. As India prepares for the Square Kilometre Array (SKA), such mathematical refinements will be the backbone of its contribution to global space science.

  1. (a) 1 and 2 only
  2. (b) 2 only
  3. (c) 1, 2 and 3
  4. (d) 1 only
Click to reveal answer
Answer: (a) 1 and 2 only — Pulsars are not standard candles; that role is played by Cepheid variables and Type Ia supernovae.

Why India Wants Fast Breeder Reactors: A Deep Dive

The PFBR criticality at Kalpakkam (April 6, 2026) is the second stage of Dr. Homi J. Bhabha’s vision, dictated by India’s resource constraints: roughly 25% of the world’s Thorium reserves but very limited Uranium.

Three-Stage Nuclear Programme

StageReactorFuelKey Output
IPHWRNatural UraniumElectricity + Plutonium-239
IIFBRMOX (Plutonium + U-238)Electricity + More Plutonium + U-233
IIIAHWRThorium-232 + U-233Electricity + Sustainable Fuel Cycle

FBR vs. PHWR: Key Differences

FeaturePHWRFBR
Neutron SpeedSlow (Thermal)Fast
ModeratorHeavy Water (D₂O)None
CoolantHeavy WaterLiquid Sodium
Fuel EfficiencyLow (~1%)High (10–60%)
Primary GoalPower + Initial Pu productionPower + Fuel Multiplication
Why FBRs Are Difficult Liquid Sodium: Catches fire on contact with air, explodes with water — requires high-precision “double-walled” heat exchangers. Corrosion: Liquid metal corrodes reactor internals over time. Cost: PFBR cost jumped from ₹3,500 crore to over ₹6,800 crore due to expensive safety systems. Only Russia operates a commercial-scale FBR besides India.

The Road Ahead

Low-Power Physics ExperimentsAERB ApprovalGrid Integration (500 MWe) → Scaling Up (two more commercial FBRs), accelerating the transition to Stage III Thorium reactors.

Conclusion: The FBR is India’s “Strategic Bridge” — turning limited Uranium into a vast pool of Plutonium, which is the only key to unlocking Thorium’s massive energy potential. While delays and costs have been significant, the successful criticality confirms India’s technological sovereignty and commitment to a “closed fuel cycle” ensuring long-term energy security without reliance on volatile global uranium markets.

Prelims Practice

  1. 1. It is part of India’s second stage of the nuclear programme.
  2. 2. It uses slow neutrons moderated by heavy water.
  3. 3. It produces more fissile material than it consumes.

Which is/are correct?

  1. (a) 1 and 3 only
  2. (b) 2 only
  3. (c) 1, 2 and 3
  4. (d) 1 only
Click to reveal answer
Answer: (a) 1 and 3 only — The FBR uses fast (not slow) neutrons and has no moderator.

Q: Explain the working principle of a Fast Breeder Reactor (FBR). How does it differ from a Pressurised Heavy Water Reactor (PHWR)? (250 Words)

Jan Vishwas 2.0: Trust-Based Compliance

Jan Vishwas 2.0 is the second iteration of a reform process aimed at decriminalizing minor, technical, and procedural defaults. By moving from a “fear-based” compliance model to a “trust-based” one, the government aims to reduce the compliance burden on businesses (especially MSMEs) and unclog the judicial system.

Jan Vishwas 1.0 vs. 2.0

FeatureJan Vishwas Act, 2023 (1.0)Jan Vishwas Bill, 2026 (2.0)
Scope183 provisions across 42 Acts784 provisions across 79 Acts
Ministries19 Ministries23 Ministries
Core ActionDecriminalized minor offencesDecriminalized 717 provisions; removed obsolete laws
ApproachReplaced fines with penaltiesIntroduced graded enforcement (warnings, lower penalties for 1st timers)

Key Pillars of the Reform

1. Decriminalization vs. Dilution Distinguishes between technical lapses (clerical errors, delayed filings) and serious violations (public safety, environmental damage). Assumes good faith; uses administrative “penalties” (faster, less stigmatizing) instead of criminal “fines” decided by courts.
2. Strengthening MSMEs Improvement Notices: Businesses get a chance to fix errors before being penalized. Reduced Compliance Anxiety: Entrepreneurs can take risks without fear of jail time for procedural mistakes.
3. Judicial Efficiency With nearly 5 crore (50 million) cases pending in Indian courts, a large chunk involves minor business defaults. Shifting these to administrative adjudication removes them from the criminal court docket. The government has signaled a retrospective review of pending cases for potential mass closure.

Challenges

Institutional Capacity: Executive officers must be trained as fair adjudicators to prevent penalties becoming a new harassment tool. Uniformity: Different ministries and states must apply decriminalized rules consistently. Retrospective Clarity: Clear guidelines needed on how pending cases will be transferred or closed.

Conclusion: Jan Vishwas 2.0 is more than a legal amendment — it is a behavioral shift in the state-citizen relationship. By removing the “shadow of the jailhouse” from the boardroom, India positions itself as a modern, investor-friendly economy. Success will depend on ground-level implementation — ensuring that reduced “criminalization” is matched by increased “regulatory clarity.”

Mains Practice

Q: Decriminalization of minor economic offences is a necessary but not sufficient condition for ‘Ease of Doing Business’ in India. Critically analyze in the context of the Jan Vishwas 2.0 Bill. (150 Words)
