India’s space agency ISRO has unveiled an ambitious 15-year roadmap — 103 satellites in orbit by 2040, Chandrayaan missions up to 8, and India’s first human lunar landing by 2040. In an exclusive interview with NDTV Science Editor Pallava Bagla, Shri Nilesh Desai shares ISRO’s vision: from 12–15 satellite launches annually, a 140-satellite internet constellation, full NAVIC operations by 2026, to building India’s big rocket for deep space missions.
