Mission Drishti: भारत का पहला OptoSAR उपग्रह SpaceX द्वारा लॉन्च किया गया – 190 kg निजी EO‑SAR प्लेटफ़ॉर्म

<p><strong>Mission Drishti</strong>, the world’s first <span class="key-term" data-definition="OptoSAR — a hybrid remote‑sensing technology that combines Electro‑Optical (EO) imaging with Synthetic Aperture Radar (SAR) to provide all‑weather, day‑and‑night Earth observation (GS3: Science & Technology)">OptoSAR</span> satellite, was launched on <strong>3 May 2026</strong> aboard a <span class="key-term" data-definition="Falcon 9 — a two‑stage, partially reusable launch vehicle developed by SpaceX, widely used for commercial and government payloads (GS3: Science & Technology)">Falcon 9</span> rocket from <strong>Vandenberg, California</strong>. Weighing <strong>190 kg</strong>, it is the largest privately‑developed Earth observation satellite from India.</p> <h3>Key Developments</h3> <ul> <li>First global integration of <span class="key-term" data-definition="Electro‑Optical (EO) sensor — an imaging system that captures visible and near‑infrared light, useful for high‑resolution daytime imagery (GS3: Science & Technology)">Electro‑Optical (EO)</span> and <span class="key-term" data-definition="Synthetic Aperture Radar (SAR) — a radar system that creates high‑resolution images regardless of cloud cover or illumination, enabling night‑time and all‑weather observation (GS3: Science & Technology)">Synthetic Aperture Radar (SAR)</span> on a single platform.</li> <li>Launch executed by <span class="key-term" data-definition="SpaceX — a private aerospace manufacturer and launch service provider founded by Elon Musk, playing a pivotal role in commercial space access (GS3: Science & Technology)">SpaceX</span>, highlighting growing Indo‑US commercial collaboration in space.</li> <li>Demonstrates the capability of Indian private sector (<strong>GalaxEye</strong>) to design, build and operate sophisticated remote‑sensing payloads.</li> </ul> <h3>Important Facts</h3> <p>The satellite, developed by Bengaluru‑based startup <strong>GalaxEye</strong>, integrates EO and SAR sensors to deliver consistent, reliable data across diverse environmental conditions. Its 190 kg mass classifies it as a small‑sat, enabling cost‑effective launch opportunities. The launch from Vandenberg marks the first Indian private satellite to be placed in orbit via a commercial launch service.</p> <h3>UPSC Relevance</h3> <p>For GS‑3 (Science & Technology), the mission illustrates the shift from government‑only space programmes to a mixed ecosystem where private firms contribute to strategic capabilities such as <span class="key-term" data-definition="Earth Observation (EO) satellite — a satellite that monitors the planet’s surface, atmosphere and oceans, providing data for disaster management, agriculture, defence and climate studies (GS3: Science & Technology)">Earth Observation</span> data. It also raises policy questions for GS‑2 (Polity) regarding regulatory frameworks for private space activities, licensing, and international collaboration. The technology’s all‑weather imaging can aid
