<h3>Important Facts</h3>
<p>The <span class="key-term" data-definition="G20 satellite — a collaborative satellite mission aimed at studying climate dynamics, air pollution, and weather patterns, reflecting India's role in global climate monitoring (GS3: Science & Technology)">G20 satellite</span> will carry instruments to measure atmospheric composition, greenhouse gases, and surface temperature, feeding data to both national and international climate models. The record <strong>104‑satellite</strong> deployment underscores India's growing commercial launch market, offering cost‑effective services to foreign customers and enhancing strategic autonomy.</p>
<h3>UPSC Relevance</h3>
<p>These developments intersect with several UPSC syllabus areas: <br/>• <strong>Science & Technology (GS3)</strong> – advances in satellite technology, launch vehicle capabilities, and climate monitoring. <br/>• <strong>International Relations (GS2)</strong> – India's participation in the G20 climate initiative reflects diplomatic engagement and soft power. <br/>• <strong>Economy (GS3)</strong> – the commercial launch sector contributes to revenue generation and technology export.</p>
<h3>Way Forward</h3>
<p>To capitalise on these achievements, policymakers should: <br/>1. Strengthen public‑private partnerships in the space sector to boost indigenous launch services. <br/>2. Integrate data from the <span class="key-term" data-definition="G20 satellite — a collaborative satellite mission aimed at studying climate dynamics, air pollution, and weather patterns, reflecting India's role in global climate monitoring (GS3: Science & Technology)">G20 satellite</span> into national climate‑action plans, aiding mitigation and adaptation strategies. <br/>3. Encourage capacity‑building programmes for scientists across ministries to utilise satellite data for agriculture, disaster management, and urban planning.</p>
