Why is India Building Its Own Space Station? Advantages Of Having Own Space Station.

India is officially taking its next giant leap in space exploration. The Indian Space Research Organisation (ISRO) has announced plans to establish its own orbital outpost, officially named the Bharatiya Antariksha Station (BAS). With the first module targeted for launch by 2028 and the fully operational station expected by 2035, India is positioning itself as a premier global space power. But what exactly is a space station? How many are currently in orbit, and what are the true benefits of India having its own?

What Is a Space Station?

A space station is essentially a large, habitable spacecraft placed in Low Earth Orbit (LEO) designed to remain in space for extended periods. Unlike traditional spacecraft, they act as permanent orbital laboratories where astronauts can live, work, and conduct microgravity research for months at a time. They also feature docking ports, allowing transport spacecraft to ferry crew and cargo back and forth from Earth.

The proposed Indian space station (BAS) will be stationed at an altitude of approximately 400 kilometers above the Earth. ISRO has stated that the initial phase of the station will weigh about 20 tonnes, allowing Indian astronauts (Gaganauts) to stay in orbit for 15 to 20 days at a time to conduct specialized experiments.

How Many Space Stations Are Currently Active?

Currently, there are two fully operational space stations orbiting Earth:

• The International Space Station (ISS): Launched in 1998, the ISS is the largest modular space station. It is a massive collaborative effort between the United States (NASA), Russia (Roscosmos), the European Space Agency (ESA), Japan (JAXA), and Canada (CSA).
• The Tiangong Space Station (TSS): Operated exclusively by China, this multi-module space station was fully completed in 2022 and maintains a constant human presence in orbit.

The True Advantages of an Indian Space Station

Operating an independent space station provides massive strategic, scientific, and economic advantages for India. While military satellites handle surveillance, a manned space station is focused on the frontiers of science and technology.

First, it will allow Indian scientists to conduct long-term microgravity research. This environment is crucial for developing new pharmaceuticals, advanced materials, and biological studies that cannot be replicated on Earth. Secondly, it drastically improves India's Earth observation capabilities for agricultural monitoring, climate tracking, and disaster management using advanced, human-tended optical equipment.

Furthermore, the Bharatiya Antariksha Station serves as a critical stepping stone. Mastering long-duration human spaceflight in LEO is a prerequisite for ISRO's ultimate ambitions: sending Indian astronauts to the Moon and eventually participating in deeper space exploration. Economically, designing, building, and maintaining the station will heavily stimulate the domestic aerospace sector, creating thousands of high-tech jobs and boosting the "Make in India" initiative.

Former ISRO Chairman G. Madhavan Nair has described the space station initiative as a highly exciting and necessary project. He noted that such complex engineering feats take time to design and realize, making the government's dedicated focus on this project a monumental milestone in ISRO's history.

How Does the ISS Work?

To understand the future of India's station, it helps to look at the ISS. The ISS orbits in Low Earth Orbit at an average altitude of 400 kilometers, traveling at roughly 28,000 km/h. It orbits the Earth once every 90 minutes.

It operates through a highly complex system of life support, solar power generation, and thermal control. Different modules provided by the participating nations serve different purposes—from sleeping quarters and exercise rooms to advanced laboratory modules. Regular supply missions bring fresh water, air, and experimental gear to the crew. India’s BAS will utilize similar, albeit domestically developed, life-support and modular technologies, proving India's complete self-reliance in cutting-edge aerospace engineering.
