Discuss India’s achievements in the field of Space Science and Technology. How the application of this technology has helped India in its socio-economic development?

India's space programme, driven by ISRO, has grown into one of the most cost-effective in the world, marrying scientific ambition with a clear developmental mandate rooted in Vikram Sarabhai's vision of applying space to national problems.

Key achievements

• Reliable launch vehicles: PSLV, the workhorse with a strong success record, and the GSLV with the indigenous cryogenic engine.
• Interplanetary missions: Mangalyaan reached Mars orbit at low cost in the first attempt; Chandrayaan missions advanced lunar exploration.
• Record multi-satellite launches and a growing commercial arm.
• Indigenous navigation (NavIC/IRNSS) and a large fleet of remote-sensing and communication satellites.

Socio-economic applications

• Communication: tele-education, tele-medicine and connectivity for remote regions via INSAT/GSAT.
• Weather and disaster management: cyclone tracking and early warning that save lives.
• Agriculture and resources: crop forecasting, soil and water mapping, forest and mineral surveys via IRS satellites.
• Governance: geospatial data for infrastructure planning, and PMFBY yield assessment.
• Navigation and security through NavIC.

Thus India's space capability is not an end in itself but a development multiplier — improving connectivity, resilience, resource management and governance — while opening a commercial and strategic frontier as the sector is progressively liberalised.
