Mission Interrupted: The PSLV-C62 Flight Path Anomaly

News Context

1. Overview of the Mission Failure

• Primary Source Link. You can read the original report regarding the mission’s trajectory failure and the resulting loss of satellites at The Hindu – PSLV-C62 strays from flight path.
• Launch Specifics. The PSLV-C62 mission, managed by NewSpace India Limited (NSIL), lifted off from the Satish Dhawan Space Centre in Sriharikota at 10:18 a.m. on Monday, January 12, 2026.
• The Final Outcome. An anomaly during the third stage caused the vehicle to deviate from its intended flight path, resulting in the total loss of the EOS-N1 satellite and 15 co-passenger payloads.

2. Technical Nature of the Anomaly

• Third-Stage Disturbance. ISRO Chairman V. Narayanan confirmed that while the first two stages performed nominally, a “disturbance in the vehicle roll rates” was detected near the end of the third stage.
• Chamber Pressure Drop. Preliminary data analysis suggested a drop in chamber pressure within the PS3 solid motor, a mechanical glitch strikingly similar to the one that downed the PSLV-C61 mission in May 2025.
• Inability to Correct. Because the third stage uses solid fuel—which acts like a firecracker that cannot be throttled or steered once ignited—ground controllers were unable to rectify the trajectory once the roll rates spiked.

3. Impact on Strategic Assets

• EOS-N1 Surveillance Satellite. The primary payload, EOS-N1 (also known as Anvesha), was a strategic earth observation satellite developed by the Defence Research and Development Organisation (DRDO).
• Surveillance Gap. The loss of this hyperspectral imaging satellite represents a significant setback for India’s national security and remote-sensing capabilities.
• Budgetary Requirements. Since the government typically does not insure strategic military assets due to high premiums, the DRDO will likely need to seek fresh budgetary approval to build a replacement.

4. Commercial and Private Payloads

• Startup Setbacks. The mission carried 15 co-passenger satellites, including several from Indian space startups like OrbitAid, which lost years of engineering research and development in minutes.
• International Participation. Payloads from global partners, including entities from the UK, Spain, Brazil, and Thailand, were also destroyed during the crash into the South Pacific Ocean.
• The KID Survival. In a rare twist, the Spanish KID (Kestrel Initial Demonstrator) capsule reportedly separated from the fourth stage and transmitted telemetry data for three minutes before contact was lost.

5. Financial Fallout and Insurance

• State-Absorbed Losses. The direct financial burden of the EOS-N1 satellite, estimated to be part of a combined development loss of over ₹700 crore, falls entirely on the Indian state.
• Private Sector Risk. Many Indian startups flew their satellites uninsured to save on high premium costs, which can reach up to 50% of the product cost, leaving them to absorb the total loss themselves.
• Commercial Payouts. International entities and larger enterprises that purchased “total loss” policies are expected to receive lump-sum payouts, though the “trust deficit” remains a harder metric to recover.

6. The “Workhorse” Under Pressure

• Reliability Concerns. This event marks the second consecutive failure of the PSLV’s third stage, causing the rocket’s lifetime success rate to dip to approximately 93.7%.
• Systemic Scrutiny. Experts are questioning whether the 30-year-old PSLV design is struggling with modern, heavier multi-satellite “rideshare” configurations that demand higher precision.
• Manufacturing Quality. The recurring nature of the PS3 failure points toward potential manufacturing defects in the solid propellant or casing materials used by subcontractors.

7. NewSpace India Limited (NSIL) Role

• Contractual Obligations. As the commercial arm of ISRO, NSIL typically operates under a “waiver of liability,” meaning they are not liable for the value of customer satellites unless gross negligence is proven.
• Refunds and Re-flights. NSIL contracts may include a “re-flight guarantee” or a refund of the launch fee, which helps mitigate some financial damage for commercial clients.
• Revenue Loss. Estimates suggest NSIL may have booked approximately ₹350 crore in launch revenues for this mission, a significant portion of which may now be lost or tied up in claims.

8. Competitive Landscape in 2026

• Global Trust Deficit. Repeated setbacks threaten the cost advantage that made ISRO a global leader, as customers may now look to competitors like SpaceX for more reliable launch windows.
• Rising Premiums. Insurance premiums for future Indian launches are expected to jump by 20-30%, potentially eroding the budget-friendly appeal of the PSLV.
• Projected Growth. Despite the failure, India’s space economy is projected to reach $44 billion by 2033, making absolute reliability a non-negotiable requirement for future growth.

9. Future Mitigation Strategies

• Third-Party Review. Following this failure, the Indian government has initiated a third-party review of the PSLV system to identify institutional challenges regarding quality control.
• Enhanced Insurance Ecosystem. The disaster has forced a conversation about building a more robust domestic space insurance market to protect the burgeoning private sector.
• Telemetry and Testing. ISRO is expected to implement more rigorous ground testing for the PS3 stage before clearing the next flight in the manifest, including the uncrewed Gaganyaan mission.

10. Social and Emotional Toll

• Heartbreak at Sriharikota. Millions watching the live stream witnessed the silence in the mission control room as telemetry screens began to signal the fatal path deviation.
• Startup Fragility. For many young engineers, the failure represents the “burning of dreams,” emphasizing the high-stakes, high-risk nature of the commercial space race.
• National Resilience. Despite the setback, industry leaders remain vocal about their continued trust in the PSLV’s long-term legacy, viewing this as a necessary, albeit painful, turning point toward perfection.
