Building on the Gaganyaan human spaceflight programme, ISRO has announced plans for an indigenous space station, the Bharatiya Antariksha Station (BAS). It marks India's transition from satellite launches to sustained human presence in low Earth orbit.

India's plan

A modular station of around 20-25 tonnes in low Earth orbit, to be built and made operational in phases, with the first module targeted around 2028 and completion by about 2035.
It is sequenced after Gaganyaan, which will validate human-rated launch (LVM3), crew module, life-support and safe re-entry.
Docking and berthing capability is being proven through the SpaDeX experiment, a prerequisite for assembling modules.

Benefits to the space programme

Microgravity research: A permanent lab for experiments in materials, biology, medicine and pharmaceuticals.
Technological mastery: Life-support, docking, in-orbit assembly and long-duration crew operations feed into deep-space ambitions like a crewed Moon mission by 2040.
Strategic autonomy and prestige: Reduces dependence on foreign platforms and strengthens India's voice in space governance.
Economic spin-offs: Stimulates the private space sector (via IN-SPACe), start-ups and high-tech jobs.

A self-owned station would anchor India's long-term human spaceflight roadmap, converting one-off missions into an enduring platform for science, security and self-reliant capability.
