PARLIAMENT QUESTION: APPLICATIONS OF SPACE TECHNOLOGY
Union Minister Dr. Jitendra Singh informed Rajya Sabha about major ISRO missions (2023-25) including Chandrayaan-3's historic Moon south pole landing, Aditya-L1 solar observatory, XPoSat X-ray polarimetry, SPADEX docking (making India 4th nation), and NISAR (NASA-ISRO dual-frequency radar). Key applications span agriculture (PMFBY support, 6.93 crore MGNREGA assets geotagged), disaster management (890+ flood products, Landslide Atlas), governance (NDEM 5.0, DIGIPIN), and satellite communication (BharatNet). Upcoming missions: Gaganyaan (human spaceflight), Venus Orbiter, Chandrayaan-4 (sample return), and Chandrayaan-5 (LUPEX with JAXA). IN-SPACe is enabling private sector participation in high-impact use cases.
