UPSC Mains 2016 GS3 Q12 — Space Technology

• Chronological or thematic evolution of major milestones (Launch vehicles, Satellites, Planetary missions).
• Direct correlation between space infrastructure and citizen-centric services like tele-medicine or education.
• The shift from purely scientific exploration to commercial and strategic utility.
• Recent reforms allowing private sector participation as a new-age achievement.

• Focusing too much on the history of ISRO and forgotten names (like Vikram Sarabhai) instead of modern technological achievements.
• Listing missions like Mangalyaan and Chandrayaan without explaining their technological significance (e.g., indigenous cryogenic engines).
• Ignoring the 'socio-economic' aspect by only writing about planetary exploration and skipping mundane but vital utilities like GPS (NavIC) or weather forecasting.
• Writing a generic essay on space instead of addressing the dual-part structure of the question.

Spend approximately 80 words on the 'Achievements' part, focusing on technical prowess like PSLV/GSLV and deep-space missions. Devote the remaining 120 words to the 'Socio-economic' application, as this is the core of the GS3 syllabus, linking specific satellites to specific development outcomes.
