- India preparing for its first human spaceflight, making re-entry systems a key technological milestone.
Relevance
GS III (Science & Tech)
- Human spaceflight, re-entry physics, thermal protection systems.
Practice Question
Q1. Explain the challenges of atmospheric re-entry in human spaceflight and how Gaganyaan ensures crew safety. (250 words)
Re-entry dynamics
- Crew module enters Earth’s atmosphere at very high speeds, generating intense heat and friction (“fireball phase”).
- Atmospheric drag acts as primary braking force, dissipating most kinetic energy.
- Controlled descent trajectory ensures precision landing within designated recovery zone.
Multi-stage deceleration system
Aerobraking phase
- Initial slowdown occurs due to interaction with Earth’s atmosphere, reducing velocity significantly.
- Requires heat shield protection to withstand extreme temperatures.
Parachute deployment
- Series of parachutes deployed sequentially to reduce speed further.
- Ensures controlled descent to safe landing velocity before splashdown.
Final landing phase
- Module lands in sea (splashdown) rather than land to minimise impact forces.
- Designed to maintain structural stability and crew safety upon impact.
Why parachutes alone are insufficient ?
- Parachutes cannot handle extremely high initial speeds of re-entry.
- Require prior velocity reduction through atmospheric drag.
- Large parachutes increase weight and design complexity, limiting feasibility.
Challenges in safe landing
- High re-entry speed and thermal stress require advanced heat shield materials.
- Small trajectory deviations can lead to large landing errors (hundreds of kilometres).
- Atmospheric conditions (winds, density variations) affect descent accuracy.
Recovery mechanism
Naval recovery operations
- Indian Navy plays key role in retrieving crew module after splashdown.
- Deployment of ships, aircraft, and tracking systems for precise location identification.
Tracking & localisation
- Use of GPS, communication systems, and electronic beacons to locate module.
- Visual tracking aids used in low-visibility conditions.
Crew extraction
- Recovery teams secure module and safely extract astronauts using specialised equipment.
- Immediate medical support provided post-recovery.
Significance
Technological advancement
- Demonstrates India’s capability in human spaceflight technologies, including re-entry systems and life-support.
- Strengthens ISRO’s expertise in precision navigation and recovery systems.
Strategic dimension
- Positions India among elite nations (USA, Russia, China) with human spaceflight capability.
- Enhances India’s role in global space exploration and collaborations.
Scientific & economic benefits

- Population declined by ~10% (2009–2018), equivalent to 20,000+ adult penguins.
- Projections indicate ~50% population decline by 2080s due to climate change.
Antarctic fur seals
- Status changed from Least Concern → Endangered.
- Population dropped from ~21.8 lakh (1999) to ~9.44 lakh (2025) → >50% decline.
- Decline linked to reduced krill availability and changing marine ecosystem dynamics.
Southern elephant seals

- Bird flu (H5N1) caused >90% mortality of pups in some colonies.
- Disease impacted 4 out of 5 major subpopulations, indicating widespread vulnerability.
Drivers of decline
Climate change impacts
- Sea-ice loss since 2016 disrupts breeding habitat of emperor penguins dependent on stable “fast ice”.
- Rising ocean temperatures push krill to deeper waters, reducing food availability for predators.
- Antarctic ecosystems highly sensitive to temperature and ice variability.
Food chain disruption
- Krill decline affects entire food web including penguins, seals, and whales.
- Increased competition with recovering whale populations further reduces food access.
Disease emergence
- Spread of Highly Pathogenic Avian Influenza (H5N1 clade 2.3.4.4b) affecting 485 bird species and 48 mammal species globally.
- Polar species more vulnerable due to low prior exposure to pathogens and dense colony living.
Ecological significance
- Emperor penguins act as sentinel species, indicating health of polar ecosystems and climate stability.
- Antarctic marine ecosystem is critical for global carbon cycles and biodiversity balance.
- Decline signals broader ecosystem degradation and climate tipping points.
Global implications
- Reflects climate-driven extinction crisis, especially in polar regions warming faster than global average.

Challenges
- Difficulty in monitoring remote polar ecosystems and translating local events into population trends.
- Limited global progress in reducing greenhouse gas emissions despite scientific warnings.
- Weak integration of climate science with conservation policy frameworks.
- Increasing unpredictability due to compounding ecological stressors.

Relevance
GS III (Environment)
- Biodiversity conservation, food chain toxicity, human-wildlife interface.
Practice Question
Q1. Analyse the causes and ecological implications of vulture mortality inIndia. Suggest conservation measures. (250 words)
Key facts & ecological context
- Species: Himalayan Griffon (Gyps himalayensis) classified as “Near Threatened” (IUCN Red List).
- Location: Buffer zone of Dudhwa Tiger Reserve, indicating human-wildlife interface vulnerability.
- Scale: 25 deaths + 6 affected birds, reflecting mass mortality event.
Cause of deaths
- Primary trigger: Consumption of carcasses of poisoned animals (likely stray dogs).
- Mechanism: Toxic substances (pesticides/chemicals) enter food chain → bioaccumulation → rapid collapse of scavengers.
- Classified as secondary poisoning, a major threat to scavenger bird populations globally.
Ecological significance of vultures
- Vultures act as natural scavengers, ensuring rapid disposal of carcasses and disease control.
- Prevent spread of zoonotic diseases like anthrax and rabies by eliminating decaying organic matter.
- Decline in vulture populations historically linked to increase in feral dog population and public health risks.
Broader conservation concerns
- India has already faced vulture crisis due to Diclofenac (NSAID toxicity), causing massive population decline in Gyps species.
- Secondary poisoning from pesticides and intentional baiting is emerging as a new major threat.
- Weak regulation and misuse of agrochemicals and toxic substances exacerbate wildlife mortality.
Governance & institutional response
- Forest Department initiated post-mortem and forensic testing, samples sent to Indian Veterinary Research Institute.
- Formation of expert panel for investigation and cause determination.
- Planned awareness campaigns for local communities to prevent use of harmful substances.
Challenges
- Unregulated pesticide use and easy availability of toxic chemicals in rural areas.
- Lack of awareness among local communities regarding ecological consequences.
- Weak monitoring in buffer zones where human-wildlife interaction is high.
- Absence of rapid response systems to detect and prevent poisoning incidents.
Way forward
- Strict regulation and monitoring of toxic chemicals and pesticides, especially near protected areas.
- Promote community awareness programmes on ecological role of vultures and risks of poisoning.
- Strengthen wildlife forensic and surveillance mechanisms for early detection of mass mortality events.
- Encourage safe carcass disposal practices and alternatives to poisoning for animal control.
- Integrate vulture conservation into broader biodiversity and public health strategies.
Prelims pointers
- Himalayan Griffon (Gyps himalayensis): scavenger bird, Near Threatened (IUCN).
- Diclofenac toxicity: major cause of vulture decline in India; banned for veterinary use.
- Secondary poisoning: occurs when predators/scavengers consume poisoned prey.
- IVRI Bareilly: premier institute for veterinary research and toxicology analysis.
