What is the PRATUSH mission?<\/strong><br>The PRATUSH mission, short for <em>Probing ReionizATion of the Universe using Signal from Hydrogen<\/em>, is a proposed Indian space mission that aims to detect the <strong>21-cm hydrogen signal<\/strong> from the universe\u2019s Cosmic Dawn using a radiometer placed in lunar orbit.<\/p>\n\n\n\n<p><strong>Q2. Why is the far side of the Moon chosen for PRATUSH?<\/strong><br>The Moon\u2019s far side is free from <strong>Earth\u2019s radio interference and ionospheric disturbances<\/strong>, making it an ideal place to capture faint cosmic signals.<\/p>\n\n\n\n<p><strong>Q3. What is unique about the PRATUSH mission\u2019s hardware?<\/strong><br>It uses a <strong>credit-card-sized single-board computer (SBC)<\/strong> as its master controller, which manages antenna operations, signal processing, calibration, and storage while minimizing weight and power consumption.<\/p>\n\n\n\n<p><strong>Q4. Which institution is leading the development of PRATUSH?<\/strong><br>The <strong>Raman Research Institute (RRI)<\/strong> in Bengaluru is spearheading the mission.<\/p>\n\n\n\n<p><strong>Q5. What signal does PRATUSH aim to detect?<\/strong><br>It targets the <strong>21-cm radio emission from hydrogen atoms<\/strong>, which can reveal information about the formation of the first stars and galaxies.<\/p>\n\n\n\n<p><strong>Q6. How does the single-board computer contribute to PRATUSH?<\/strong><br>The SBC coordinates the radiometer, processes raw data using FPGA systems, applies real-time calibrations, and ensures precise data storage.<\/p>\n\n\n\n<p><strong>Q7. What are the advantages of using SBC in space missions?<\/strong><br>They are <strong>lightweight, energy-efficient, and cost-effective<\/strong>, making advanced space instruments more feasible and scalable.<\/p>\n\n\n\n<p><strong>Q8. How sensitive is the PRATUSH digital receiver system?<\/strong><br>Laboratory tests show it can detect signals with noise levels as low as a few <strong>millikelvins<\/strong>, making it extremely precise.<\/p>\n\n\n\n<p><strong>Q9. Why is the 21-cm hydrogen signal important?<\/strong><br>This signal is a direct tracer of hydrogen distribution during the <strong>Cosmic Dawn<\/strong>, helping scientists understand how the first stars and galaxies formed.<\/p>\n\n\n\n<p><strong>Q10. How is PRATUSH relevant for competitive exams?<\/strong><br>It is a significant <strong>Science &amp; Technology<\/strong> development in India, making it relevant for <strong>UPSC, PSCs, Banking, Railways, Defence, and Civil Service exams<\/strong> under topics like astronomy, innovation, and space research.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"
