What happened
India's space programme, spanning over five decades, has progressed from the 1975 Aryabhata satellite to ambitious missions like Chandrayaan, Mangalyaan, and the upcoming crewed Gaganyaan mission. ISRO now operates launch vehicles PSLV, GSLV, and LVM3, supports remote sensing, navigation (NavIC), and communication satellites, and has opened the sector to private players through IN-SPACe. India ranks among the top spacefaring nations, having demonstrated cost-effective deep-space missions and indigenous cryogenic engine technology.

Why it matters
India's space sovereignty rests on three pillars: self-reliance in launch capability, indigenous satellite development, and an expanding application ecosystem.
Launch Vehicles: PSLV (Polar Satellite Launch Vehicle) is ISRO's workhorse for sun-synchronous and polar orbits. GSLV (Geosynchronous Satellite Launch Vehicle) uses indigenous cryogenic engines developed after technology denial by the US in the 1990s. LVM3 (Launch Vehicle Mark-3), formerly GSLV Mk-III, is India's heaviest rocket, used for Chandrayaan-2, OneWeb launches, and will carry Gaganyaan.
Key Missions: Chandrayaan-1 (2008) discovered water molecules on the Moon. Chandrayaan-3 (2023) made India the first country to land near the lunar south pole. Mangalyaan (Mars Orbiter Mission, 2013) made India the first Asian nation to reach Martian orbit and the first in the world to succeed on its maiden attempt. Aditya-L1 (2023) is India's first solar observatory, placed at the L1 Lagrange point.
Navigation: NavIC (Navigation with Indian Constellation), formerly IRNSS, provides regional positioning services with seven satellites covering India and 1,500 km beyond its borders.
Private Sector: IN-SPACe (Indian National Space Promotion and Authorisation Centre) was established in 2020 to enable private participation. The Space Activities Bill and the new Space Policy 2023 further define the regulatory framework.
Gaganyaan: India's first crewed mission, targeting low Earth orbit, will make India the fourth country to independently send humans to space. The mission uses the Human-Rated LVM3 and a Crew Escape System tested successfully.
