The experiment involved:\n<ul>\n<li><strong>Docking:<\/strong> Two 220-kg satellites, SDX01 and SDX02, were maneuvered into the same orbit and progressively brought closer until they were joined on January 16, 2025.<\/li>\n<li><strong>Power Sharing:<\/strong> The mission demonstrated power-sharing capabilities, where both satellites operated as a single composite unit.<\/li>\n<li><strong>Undocking:<\/strong> On March 14, the capture levers were released, and the satellites were commanded to separate, successfully completing the undocking operation.<\/li>\n<\/ul>\n<\/li>\n<li>ISRO officials took their time before executing the undocking manoeuvre to ensure every step was thoroughly analysed, as this was the agency\u2019s first attempt at such a mission.<\/li>\n<\/ul>\n<h2>Significance of this Capability<\/h2>\n<ul>\n<li><strong>Chandrayaan-4 and Lunar Sample Return Missions<\/strong>\n<ul>\n<li>ISRO plans to launch <strong>Chandrayaan-4<\/strong>, a mission aimed at bringing back lunar surface samples. This will require two critical docking operations:\n<ul>\n<li><strong>In Lunar Orbit:<\/strong> The ascender module carrying Moon samples will dock with a transfer module.<\/li>\n<li><strong>In Earth Orbit:<\/strong> The transfer module will dock with a re-entry module, which will carry the samples back to Earth.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>The Bharatiya Antariksha Station (India\u2019s Own Space Station)<\/strong>\n<ul>\n<li>India is working on launching its own space station, the <strong>Bharatiya Antariksha Station<\/strong>, by 2035.
