Bharatiya Antariksha Station (BAS): India to Establish Its Own Space Station by 2035

Why in news?

India’s Bharatiya Antariksha Station (BAS) is in the news after ISRO Chairman Dr. V. Narayanan announced on 23 August 2026 that India aims to establish its own space station by 2035.

What is the Bharatiya Antariksha Station?

• The Bharatiya Antariksha Station (BAS) is India’s planned modular space station that will serve as an orbital platform for scientific research, technology development and human spaceflight activities.
• According to the Department of Space, ISRO has worked out an overall configuration comprising five modules. The Union Cabinet had already approved the development and launch of the station’s first module, BAS-01, by 2028, as part of the expanded Gaganyaan programme.
• The remaining modules are planned to be added progressively, with the complete station targeted for establishment by 2035.

BAS and Gaganyaan: How are they connected?

• The Bharatiya Antariksha Station is closely linked with India’s Gaganyaan human spaceflight programme.
• Gaganyaan is intended to develop and demonstrate the technologies required to safely send Indian astronauts into space and bring them back to Earth. These capabilities—including human-rated launch systems, life-support technologies, crew safety and mission operations—will also be essential for future long-duration missions aboard BAS.
• Thus, Gaganyaan can be seen as a critical technological foundation for India’s longer-term human spaceflight ambitions.

Why is the Space Station Important?

• The BAS will provide India with a dedicated platform for conducting experiments in the microgravity environment of space. Such research can contribute to advances in areas including materials science, biology, medicine, physics and space technology.
• The station could also help India develop expertise in:
  • Long-duration human spaceflight
  • Life-support and crew habitation systems
  • Space-based scientific research
  • Robotic and autonomous operations
  • Space docking and rendezvous technologies
  • Technology demonstrations in microgravity
• In the longer term, experience gained from BAS could support India’s planned human lunar exploration programme.

From Chandrayaan-3 to Sustained Human Presence

• India’s space programme has achieved major milestones in recent years. The Chandrayaan-3 mission successfully soft-landed near the Moon’s south polar region in August 2023, making India the first country to achieve a soft landing in the region.
• The landing site was named Shiv Shakti Point, and 23 August was subsequently designated as National Space Day.
• The BAS represents a different but complementary dimension of India’s space ambitions. While Chandrayaan missions demonstrate India’s planetary exploration capabilities, a space station would demonstrate its ability to support continuous human operations in orbit.

Private Sector Gets a Larger Role

• India’s expanding space ecosystem is also expected to contribute to the development of BAS. Union Minister Gajendra Singh Shekhawat, speaking at the National Space Day event, highlighted the growing role of private companies in the space sector.
• Private industry is increasingly involved in areas such as satellite manufacturing, payload development, space applications and launch services. This expanding ecosystem can complement ISRO’s core research and mission responsibilities and increase the country’s overall space-sector capacity.

India’s Long-Term Space Vision

• The Bharatiya Antariksha Station forms part of a broader long-term roadmap for India’s human space programme. The planned sequence includes developing human-spaceflight capabilities through Gaganyaan, establishing BAS by 2035, and eventually pursuing human missions to the Moon.
• The space station will therefore not merely be an orbital laboratory; it could become an important stepping stone towards more ambitious deep-space missions.
