India observes its third National Space Day on 23 August 2026

India observes its third National Space Day on 23 August 2026, commemorating the historic soft landing of Chandrayaan-3’s Vikram lander near the lunar south polar region in 2023 and highlighting India’s expanding capabilities in space science and technology.

National Space Day

¨     National Space Day is observed every year on 23 August to commemorate the successful soft landing of the Vikram lander of Chandrayaan-3 on the Moon in 2023.

¨     India became the fourth country to achieve a soft landing on the Moon and the first to land near the lunar south polar region.

¨     The landing site was named Shiv Shakti Point, and Vikram subsequently deployed the Pragyan rover for scientific experiments.

¨     The theme of National Space Day 2026 is “Towards Viksit Bharat: Innovating, Collaborating and Aspiring to Global Space Leadership.” It reflects India’s focus on innovation, collaboration, self-reliance and greater participation in the global space ecosystem.

Space Sector in India

¨     Space Ecosystem: India opened the space sector to private participation in 2020 and introduced the Indian Space Policy 2023. IN-SPACe authorises and facilitates private-sector space activities, while NewSpace India Limited (NSIL) commercialises ISRO technologies and services.India had around 440 registered space start-ups in 2026. IN-SPACe has granted 113 authorisations to 52 Non-Government Entities, including 18 start-ups.

¨     Space Economy: India’s space economy was valued at around US$8.4 billion in 2023 and is projected to reach about US$44 billion by 2033.

¨     Launch Vehicles and Infrastructure: India operates PSLV, GSLV, LVM3 and SSLV for satellite launches, space science missions and commercial launches.The Next Generation Launch Vehicle (NGLV) and reusable launch vehicle technologies are under development. The third launch pad at Sriharikota and the Kulasekarapattinam spaceport in Tamil Nadu will expand launch capacity.

¨     NavIC and Space Applications: NavIC (Navigation with Indian Constellation) provides positioning, navigation and timing services across India and up to 1,500 km beyond its borders.Space technology supports agriculture, disaster management, weather forecasting, water-resource management, healthcare, education, communication and governance.

Space Missions in India

Lunar Exploration:

¨     Chandrayaan-1 (2008): India’s first lunar mission; provided evidence of water molecules and hydroxyl on the Moon.

¨     Chandrayaan-2 (2019): Advanced lunar exploration through its orbiter and attempted a soft landing near the lunar south polar region.

¨     Chandrayaan-3 (2023): Achieved India’s first successful soft landing near the lunar south polar region.

¨     Chandrayaan-4: Planned to demonstrate lunar sample collection and return to Earth.

¨     LUPEX/Chandrayaan-5: India-Japan mission aimed at studying lunar polar regions and volatiles, including water.

Interplanetary and Solar Missions

¨     Mars Orbiter Mission (2014): Made India the first country to reach Mars orbit on its maiden attempt.

¨     Aditya-L1 (2023): India’s first dedicated solar mission, positioned around the Sun-Earth L1 point.

¨     Venus Orbiter Mission: Targeted for 2028 to study Venus’ atmosphere, surface and geological processes.

Space Science and Advanced Technologies

¨     AstroSat (2015): India’s first dedicated multi-wavelength space observatory.

¨     XPoSat (2024): Strengthened India’s capability in X-ray polarisation astronomy.

¨     SpaDeX (2025): Demonstrated autonomous docking and undocking in space, making India the fourth country to demonstrate this capability.

Human Spaceflight and Space Station

¨     Gaganyaan aims to demonstrate India’s indigenous human spaceflight capability by carrying three astronauts to a 400-km orbit for up to three days and safely returning them to Earth.

¨     The Bharatiya Antariksh Station (BAS) is India’s planned five-module space station, targeted for operationalisation by 2035, and is intended to support long-duration human spaceflight and microgravity research.

Chandrayaan-3

¨     Chandrayaan-3, launched on 14 July 2023 aboard LVM3-M4, comprised a Propulsion Module, Lander Module and Rover.

Its three objectives were to

¨     Demonstrate a safe and soft landing on the Moon.

¨     Demonstrate rover mobility.

¨     Conduct in-situ scientific experiments.

On 23 August 2023, Vikram landed at Shiv Shakti Point and deployed the Pragyan rover. The mission studied the lunar surface, thermal properties, seismic activity, plasma environment and elemental composition. APXS detected sulphur near the landing site. The mission’s findings also supported the Lunar Magma Ocean hypothesis. Chandrayaan-3 strengthened India’s capabilities for lunar sample return, human spaceflight, space stations and future planetary exploration
