UPSC Editorial Analysis: ISRO’s Recent Setbacks

*General Studies-3; Topic: Science and Technology- developments and their applications and effects in everyday life.*

Introduction

• The failure of PSLV-C62, which followed the PSLV-C61 failure within eight months, marks a rare and concerning trend for the Indian Space Research Organisation (ISRO).

• The PSLV has historically been the backbone of India’s space missions, known for its reliability and “cost-to-payload” efficiency.

• However, two consecutive failures centered around the third stage (PS3) have triggered a crisis of confidence.

About ISRO’s Recent Setbacks

• ISRO‘s recent PSLV-C62 and C61 failures, linked to third-stage anomalies, have stalled strategic surveillance missions and dented its “workhorse” reputation, requiring urgent quality-control reforms to restore global commercial trust.

Technical Dimensions: The “Third Stage” Problem

• The Propulsion System: The PSLV is a four-stage vehicle. The first and third stages use solid propellants, while the second and fourth use liquid propellants.

• The Specific Anomaly: Both C61 (May 2025) and C62 showed issues during the PS3 burn. In C61, a pressure drop in the combustion chamber was identified. C62 suggests a similar terminal-phase anomaly in the solid motor.

• Manufacturing vs. Design: Since the PSLV is a mature design, these failures point toward potential Quality Assurance (QA) lapses or issues in the manufacturing/casting of the solid propellant rather than a fundamental design flaw.

Strategic Implications: The Loss of EOS-N1

The primary payload, EOS-N1, was a high-stakes asset for India’s national security and governance.

• Hyperspectral Imaging (HSI): Unlike standard optical sensors, HSI captures data across hundreds of narrow spectral bands. This allows for “material fingerprinting”—the ability to distinguish between a camouflaged tank and the surrounding foliage.

• Surveillance Gap: The loss of this satellite creates a gap in India’s Space-Based Surveillance (SBS) capabilities at a time of heightened regional geopolitical tension.

Commercial and Global Market Dimensions

ISRO’s commercial arm, NewSpace India Limited (NSIL), operates in a highly competitive global market.

• Market Share at Risk: The global small-satellite launch market is valued at billions of dollars. Companies like SpaceX (Falcon 9) and Rocket Lab provide stiff competition.

• International Partnerships: PSLV-C62 carried 15 payloads from Spain, Brazil, and Nepal. Repeated failures could lead these nations to seek more “reliable” alternatives, despite ISRO’s cost advantage.

• Insurance Costs: Frequent failures lead to higher insurance premiums for satellites launched via PSLV, effectively neutralizing India’s low-cost advantage.

Institutional and Reputational Dimensions

• The “Chandrayaan Effect”: Following the global acclaim of Chandrayaan-3, the public and government expectations are at an all-time high. A failure in a “routine” launch vehicle like the PSLV is perceived more harshly than a failure in an experimental mission.

• Credibility of the “Workhorse” Label: The PSLV has flown 64 missions with only five failures (a ~92% success rate). While statistically strong, the clustering of failures suggests an institutional “fatigue” or a need for modernizing the production line.

• Human Resource Strain: With ISRO simultaneously focusing on Gaganyaan, the Moon, and the Sun (Aditya), resources and senior expertise may be stretched thin across too many high-priority verticals.

Impact on Future Missions

• Gaganyaan (Human Spaceflight): Although Gaganyaan uses the LVM3, any failure within ISRO’s ecosystem triggers a “pause” and a rigorous safety audit, potentially delaying the human spaceflight timeline.

• Bharatiya Antariksha Station: The goal of an Indian space station by 2035 relies on a high frequency of successful launches. These setbacks necessitate a re-evaluation of the “assembly line” approach to rocket manufacturing.

Conclusion

• While consecutive PSLV failures are a significant setback, they offer a critical opportunity for ISRO to institutionalize more rigorous quality controls.

• By addressing the PS3 stage anomalies transparently and leveraging private sector partnerships, India can restore global confidence, ensuring its “workhorse” remains a reliable pillar for future strategic and commercial milestones.

Despite having multiple launch vehicles, ISRO faces constraints in launching heavy payloads and scientific missions.
