<h4>What is PRATUSH?</h4><p><strong>PRATUSH</strong> is an innovative Indian project, conceptualized as a specialized <strong>radio telescope</strong>. Its unique design specifies its placement on the <strong>far side of the Moon</strong>, a location chosen for its scientific advantages.</p><div class='info-box'><p><strong>PRATUSH</strong> is a collaborative endeavor, developed jointly by two leading Indian scientific organizations:</p><ul><li>The <strong>Raman Research Institute (RRI)</strong>, based in Bengaluru.</li><li>The <strong>Indian Space Research Organisation (ISRO)</strong>.</li></ul></div><h4>Core Objective: Unveiling Cosmic Dawn</h4><p>The primary scientific objective of <strong>PRATUSH</strong> is to explore the mysteries of the <strong>early universe</strong>. It specifically targets the epoch known as <strong>Cosmic Dawn</strong>.</p><div class='key-point-box'><p>The <strong>Cosmic Dawn</strong> represents a crucial period in universal history. It marks the time when the <strong>first sources of radiation</strong>, including the very first <strong>stars</strong> and <strong>galaxies</strong>, began to form.</p></div><p><strong>PRATUSH</strong> aims to precisely determine the <strong>timing</strong> and fundamental <strong>characteristics</strong> of these inaugural star formations. This includes understanding the specific <strong>colour of the light</strong> emitted during this profound era.</p><p>Ultimately, the mission seeks to trace the universe's evolution. It aims to map its journey from an initial state of <strong>cold gas</strong>, following the <strong>Big Bang</strong>, to the complex structure of <strong>stars</strong>, <strong>galaxies</strong>, and the cosmos we observe today.</p><h4>Advanced Capabilities of PRATUSH</h4><p>To achieve its ambitious scientific goals, <strong>PRATUSH</strong> is equipped with highly sophisticated <strong>radio equipment</strong>, tailored for deep space observation.</p><div class='info-box'><ul><li><strong>Frequency Range:</strong> It is designed to operate across a broad frequency spectrum, specifically from <strong>30 to 250 MHz</strong>.</li><li><strong>Observation Strategy:</strong> The telescope will continuously monitor <strong>large areas of the sky</strong>.</li><li><strong>Data Acquisition:</strong> It will record highly detailed <strong>radio spectra</strong>.</li><li><strong>Spectral Resolution:</strong> It boasts an impressive resolution of <strong>100 kHz</strong> for precise spectral analysis.</li></ul></div><p>The system incorporates several custom-engineered components essential for its performance:</p><ul><li>A specially designed <strong>antenna</strong> to capture faint radio signals.</li><li>An advanced <strong>analog receiver</strong> for initial signal processing.</li><li>A sophisticated <strong>digital correlator</strong>, crucial for high-resolution spectral analysis of the collected data.</li></ul>
