Why this matters now
The space sector is undergoing global transformation — falling launch costs (SpaceX reusability), commercial New Space, mega-constellations (Starlink), strategic competition (US-China-Russia-India). India's New Space Policy 2023 represents a fundamental shift from state monopoly to public-private partnership. The next decade will determine India's position in the $1.8 trillion space economy projected by 2035.

Chandrayaan-3 — 23 August 2023
Launched 14 July 2023 by LVM3 from Sriharikota. Lander Vikram and rover Pragyan landed on the lunar south pole at 6:04 PM IST on 23 August 2023.
Significance:
- India 4th country to soft-land (after USSR, USA, China);
- First country on lunar south pole;
- Followed Chandrayaan-2's 2019 lander failure — resilience;
- ₹615 crore cost — extraordinarily cheap;
- Pragyan rover operated 14 Earth days; discovered sulphur, oxygen, aluminium, calcium, iron, chromium, titanium, manganese in lunar regolith;
- 23 August declared National Space Day;
- PM Modi witnessed landing from Johannesburg (BRICS summit).
Team: S. Somanath (ISRO Chairman), P. Veeramuthuvel (project director), Ritu Karidhal (deputy director).
Lunar south pole strategic because: water ice in permanent shadow craters; sustained sunlight on crater rims; potential Moon base resource; US Artemis programme also targets south pole.
Aditya-L1 — solar mission
Launched 2 September 2023 by PSLV-C57. India's first dedicated solar observation mission. Reached L1 Lagrangian point (1.5 million km from Earth, toward Sun) on 6 January 2024.
Mission: study Sun continuously without eclipse/occultation. 7 instruments — VELC (Visible Emission Line Coronagraph), SUIT, ASPEX, PAPA, SoLEXS, HEL1OS, magnetometer.
Significance: makes India 4th country with active solar observation at L1 (NASA SOHO, ACE; ESA partners); valuable for solar weather forecasting, climate study, satellite operations protection.
Gaganyaan — India's human spaceflight
India's first human spaceflight programme. Announced PM Modi 2018 Independence Day speech.
Status:
- Budget ₹9,023 crore (₹20,000+ crore including infrastructure);
- Timeline: uncrewed tests 2024-25; first crewed 2026;
- 4 astronaut-designates: Group Captains Prashanth Balakrishnan Nair, Ajit Krishnan, Angad Pratap; Wing Commander Shubhanshu Shukla;
- Trained in Russia (Glavkosmos) 2020-21;
- Shubhanshu Shukla flew on Axiom-4 mission to ISS June 2025 (private mission; preparation experience);
- Crew Escape System tested October 2023 (TV-D1);
- LVM3 human-rated.
Long-term vision (PM Modi 2024 Independence Day):
- Bharatiya Antariksha Station (Indian Space Station) by 2035;
- Indian astronaut on the Moon by 2040.
Gaganyaan would make India the 4th nation (after Russia, USA, China) to independently send humans to space.

Indian Space Policy 2023
Approved by Cabinet 6 April 2023. Ends ISRO monopoly; opens to private industry.
Role definitions
- ISRO — research, exploration, sovereign missions;
- NSIL — commercial activities;

Future vision
PM Modi's 2024 Independence Day announcement set ambitious targets:
- Bharatiya Antariksha Station by 2035;
- Indian astronaut on Moon by 2040;

- Lunar Polar Exploration Mission with Japan;
- Venus Orbiter Mission;
- Mars Lander.
India's space programme is at an inflection point — combining ISRO's proven engineering with private sector dynamism under the New Space Policy.
"India's space programme is the most successful technology programme of the post-Independence era — combining frugal engineering, strategic vision, and democratic accountability." — paraphrasing the ISRO Vision 2047 document
