<h2>ISRO’s Transparency on NVS‑02 Anomaly and Subsequent Success</h2>
<p>The <span class="key-term" data-definition="Indian Space Research Organisation — India’s premier space agency responsible for satellite launches, planetary missions and space technology development (GS3: Science & Technology)">ISRO</span> has released the report of a technical committee that examined why the <span class="key-term" data-definition="NVS‑02 — Navigation satellite launched on 29 January 2025 that failed to reach its planned orbit (GS3: Science & Technology)">NVS‑02</span> could not be placed in its intended orbit after launch aboard a <span class="key-term" data-definition="GSLV — Geosynchronous Satellite Launch Vehicle, a medium‑to‑heavy lift launch vehicle used by ISRO for placing satellites into geostationary orbit (GS3: Science & Technology)">GSLV</span> on 29 January 2025.</p>
<h3>Key Developments</h3>
<ul>
<li>The apex committee concluded that a signal meant to activate a critical valve in the engine’s oxidiser line never reached the valve.</li>
<li>The failure was traced to a loose or failed connection in the electrical connector of both primary and backup lines.</li>
<li>Corrective measures were incorporated in the <span class="key-term" data-definition="LVM‑3 M5 — The fifth mission of ISRO’s LVM‑3 launch vehicle, a heavy‑lift rocket used for high‑value payloads (GS3: Science & Technology)">LVM‑3 M5</span> launch on 2 November 2025, successfully placing the <span class="key-term" data-definition="GSAT‑7R — India’s heaviest communication satellite launched in November 2025 (GS3: Science & Technology)">GSAT‑7R</span> into its planned orbit.</li>
<li>ISRO has also set up a separate committee to probe systemic issues behind the back‑to‑back failures of the <span class="key-term" data-definition="Polar Satellite Launch Vehicle (PSLV) — ISRO’s workhorse launch vehicle for low‑to‑medium‑orbit missions, which suffered failures in January and May 2025 (GS3: Science & Technology)">PSLV</span> in 2025.</li>
</ul>
<h3>Important Facts</h3>
<p>• The technical committee’s report, unlike the press note, provides a detailed engineering diagnosis of the valve‑signal failure.<br/>
• The identified fault involved both the primary and redundant electrical pathways, indicating a lapse in quality‑control checks during assembly.<br/>
• ISRO claims the lessons learned were “successfully implemented” in the subsequent LVM‑3 M5 mission, demonstrating rapid corrective action.
</p>
<h3>UPSC Relevance</h3>
<p>Understanding ISRO’s failure‑analysis process is crucial for several UPSC topics:</p>
<ul>
<li>Science & Technology (GS3) – The role of systematic failure analysis, risk mitigation, and technology transfer in large‑scale projects.</li>
<li>Governance & Institutional Accountability (GS2) – How public sector agencies balance transparency with strategic confidentiality.</li>
<li>Policy Implementation (GS3) – The importance of feedback loops and corrective mechanisms in achieving mission success.</li>
</ul>
<h3>Way Forward</h3>
<p>To strengthen credibility and operational reliability, ISRO should consider:</p>
<ul>
<li>Publishing full <span class="key-term" data-definition="Failure Analysis Report – A detailed document that investigates the root cause of a technical failure and recommends corrective actions, essential for learning and accountability (GS3: Science & Technology)">Failure Analysis Report</span> with clear attribution of systemic versus human errors, while safeguarding sensitive data.</li>
<li>Enhancing assembly‑line inspection protocols, including automated torque‑verification and redundancy checks for critical connectors.</li>
<li>Establishing an independent oversight body to review high‑risk missions, thereby reinforcing public confidence.</li>
<li>Continuing to document and disseminate lessons learned across all launch‑vehicle programmes to prevent recurrence.</li>
</ul>
<p>By adopting greater openness and robust quality‑control measures, ISRO can maintain its strategic edge while upholding the transparency expected of a premier public institution.</p>
