India to Launch Its Own Space Station by 2035: ISRO’s Bold Leap Toward Orbital Independence
In a landmark declaration that could reshape India’s trajectory in space exploration, ISRO Chairman Dr. V. Narayanan announced that the country aims to establish its own fully operational space station by the year 2035. Speaking at the 14th convocation of IIT-BHU, Narayanan revealed that initial module deployments could begin as early as 2027, marking the dawn of India’s long-term human presence in space.
With this vision, India joins the ranks of space powers such as the United States, Russia, and China—nations that have built and operated their own orbital laboratories. The proposed facility, tentatively called the Bharatiya Antariksh Station (BAS), will not only advance scientific research in microgravity but also demonstrate India’s self-reliance in human spaceflight, orbital maintenance, and deep-space mission preparation.
The Vision Behind the Space Station
Dr. Narayanan’s statement follows a series of progressive steps taken by ISRO over the past decade, culminating in the success of Chandrayaan-3 in 2023 and the upcoming Gaganyaan human spaceflight mission. These milestones have laid the groundwork for India’s next frontier — establishing an independent orbital platform that can host astronauts for extended durations.
“By 2035, we envision an Indian space station that reflects our scientific excellence and our aspiration to explore space sustainably,” Narayanan said. “We are not merely building hardware; we are creating a long-term ecosystem for innovation, research, and international collaboration.”
According to ISRO sources, the BAS will operate at an altitude of approximately 400 kilometers, similar to the International Space Station (ISS), but designed for compact, modular expansion. The project, estimated to weigh around 52 tons in total, is expected to support a crew of three to four astronauts during regular missions.
India’s Space Legacy and the Road So Far
India’s journey toward a space station has been gradual but steady. Since the first indigenous satellite Aryabhata launched in 1975, ISRO has evolved from a modest research body into a world-class space agency capable of interplanetary exploration. Missions such as Mangalyaan (Mars Orbiter Mission), Chandrayaan-2 and 3, and Aditya-L1 have proven India’s capabilities across lunar, solar, and planetary science.
The Gaganyaan program, initiated in 2018, became the cornerstone for India’s human spaceflight ambitions. Its goal: to send Indian astronauts, or “vyomanauts,” into low Earth orbit aboard an indigenously built spacecraft. The success of this program will directly feed into the design and operational experience required for BAS. ISRO has already tested crucial technologies such as the crew escape system and re-entry modules under extreme conditions.
Parallel to these advancements, India’s private space ecosystem has grown rapidly, with startups like Skyroot Aerospace and Agnikul Cosmos contributing to reusable launch vehicles and small satellite deployment systems. These developments indicate a robust future where both public and private sectors collaborate on large-scale orbital projects.
Technical Blueprint of the Bharatiya Antariksh Station
According to concept documents and early design discussions, the Bharatiya Antariksh Station will feature multiple modular segments: a Core Habitat Module for life support and control, a Science Laboratory Module for research, a Power and Docking Module, and a Service Module containing propulsion and communication systems. Each module will be launched separately using India’s upcoming Next-Generation Launch Vehicle (NGLV) or a modified LVM3 rocket.
The station will orbit Earth in a near-equatorial trajectory of 51.5°, ensuring maximum launch flexibility from the Satish Dhawan Space Centre in Sriharikota. Power will be supplied through expansive solar arrays capable of generating over 25 kW of electricity, while thermal and radiation shielding will be enhanced to meet international crew safety standards.
ISRO engineers have also proposed the use of a common berthing mechanism that would allow visiting spacecraft—both crewed and cargo—to dock autonomously. This modular approach enables incremental assembly and easier maintenance while also allowing future integration with private research modules or international payloads.
Timeline and Implementation Phases
The official timeline, though subject to refinement, envisions the first unmanned test module by 2027. This will validate orbital deployment, power systems, and long-term stability. Between 2028 and 2030, ISRO expects to launch additional laboratory and docking modules, expanding the station’s capabilities step by step. By 2032, India aims to conduct its first crewed mission to the partially assembled structure, paving the way for full-time habitation by 2035.
These stages align closely with the Gaganyaan program’s roadmap, which is expected to send its first astronauts on a short-duration orbital mission in 2026 or 2027. Once those missions demonstrate crew life-support reliability and safe re-entry, the technology will transition directly into BAS’s operational framework.
Experts believe this incremental approach — build, test, validate, expand — will be crucial in balancing ambition with safety. Unlike the rapid, high-budget programs of the Cold War era, India’s station will be a product of sustainable engineering and iterative learning.
Scientific Objectives and Potential Research Areas
Beyond its symbolic importance, the Bharatiya Antariksh Station is expected to be a powerhouse of scientific discovery. Experiments in microgravity biology, material science, fluid dynamics, and astrophysics will become central to its mission. The platform will enable Indian researchers to conduct experiments that cannot be performed under Earth’s gravity, opening new frontiers in pharmaceuticals, crystal growth, and 3D printing in orbit.
ISRO has also hinted at plans to use the station as a testbed for future deep-space technologies—such as in-space assembly, autonomous docking, and long-term life-support systems that will be essential for human missions to the Moon and Mars. The experience gained here could form the backbone of India’s broader 2040 vision, which includes a crewed lunar landing and participation in global deep-space exploration networks.
Challenges Ahead: Funding, Technology, and Sustainability
Building a space station is among the most complex engineering challenges ever undertaken. Experts caution that ISRO will need not only technological breakthroughs but also consistent funding and political commitment over the next decade. Unlike robotic missions, maintaining a human-habitable platform involves long-term operational costs — from life-support logistics to resupply and maintenance.
Dr. Ajey Lele, senior fellow at the Manohar Parrikar Institute for Defence Studies and Analyses, emphasized that “the technological leap from Gaganyaan to a space station is significant. ISRO must master crewed docking, orbital servicing, and long-duration habitability — areas that require rigorous testing and international collaboration.”
ISRO is already developing critical systems like regenerative oxygen generation, carbon dioxide scrubbing, and advanced water recycling — all vital for sustainable crewed missions. The agency may also partner with private logistics providers for periodic cargo resupply, mirroring NASA’s collaboration model with SpaceX and Northrop Grumman.
Global Context and Strategic Significance
The announcement comes at a time when the International Space Station nears its planned retirement in the early 2030s. With China’s Tiangong station already operational, India’s entry will help ensure continued human presence in low Earth orbit from the Global South. Strategically, it will give India a foothold in orbital diplomacy — a domain that blends science, defense, and international prestige.
By developing its own station, India can secure autonomy in crewed space access, reduce dependence on foreign platforms, and open opportunities for regional collaboration. Smaller nations in Asia, Africa, and Latin America could potentially partner with ISRO to conduct experiments aboard the Indian facility, thereby democratizing access to space research.
Moreover, the BAS project aligns with India’s commitment to peaceful space utilization under UN guidelines, ensuring that its orbital infrastructure serves scientific and humanitarian goals rather than militarization.
Economic and Industrial Ripple Effects
A domestic space station will also stimulate India’s growing space economy, currently valued at over $10 billion and projected to reach $40 billion by 2040. The construction, operation, and maintenance of BAS will require new industries — from advanced materials manufacturing and robotics to AI-driven mission control and biomedical engineering.
Private companies will likely play a major role in building subsystems and supply chains. As Narayanan noted, “The future of Indian space exploration will be co-created by ISRO and the private sector.” The upcoming Indian Space Policy 2025 emphasizes public-private partnerships, encouraging domestic firms to develop space-grade electronics, propulsion systems, and orbital logistics services.
Educational and Inspirational Impact
Perhaps the most enduring impact of the Bharatiya Antariksh Station will be its inspiration to India’s youth. Much like how the Apollo missions inspired generations of scientists and engineers in the West, the BAS project could ignite a new wave of curiosity and innovation in Indian classrooms and laboratories.
Universities are already gearing up to contribute. IITs and IISc are working with ISRO on student payloads and biological experiments for upcoming orbital test missions. The Department of Space has hinted at creating fellowship programs to train young researchers in space biology, robotics, and orbital engineering.
This academic involvement ensures that BAS will be not only a technological marvel but also a national classroom in orbit — one that teaches the world about India’s scientific resolve.
Looking Ahead: The 2035 Horizon
As ISRO steps into this defining chapter, the space station represents more than a scientific endeavor — it symbolizes India’s confidence in its technological destiny. The coming decade will test the nation’s ability to sustain large-scale, multi-phase projects that demand both precision and patience. But if achieved, BAS will stand as a beacon of innovation in the Indian sky, orbiting as a living tribute to decades of perseverance.
Dr. Narayanan summarized it aptly: “When we build our space station, it won’t just orbit the Earth — it will orbit the dreams of 1.4 billion Indians.”
