Background: India’s Early Space Aspirations

Scientific Vision After Independence

After gaining independence in 1947, India faced immense challenges related to poverty, development, and technological backwardness. Despite limited resources, Indian leaders and scientists strongly believed that science and technology were essential for national progress. Space research was viewed not as a luxury but as a tool for addressing practical problems such as weather prediction, agriculture, communication, and disaster management.

Role of Visionary Leaders

The foundation of India’s space program was laid by pioneers like Dr. Vikram Sarabhai, often regarded as the father of the Indian space program. He envisioned the use of space technology for societal benefit rather than military dominance. According to Sarabhai, developing nations like India should focus on applying space science to solve real-world problems.

Birth of Meteorological Rocket Research in India

Need for Atmospheric Studies

Weather forecasting plays a critical role in a country like India, where agriculture heavily depends on the monsoon. In the 1960s, India lacked reliable high-altitude atmospheric data, making accurate weather prediction difficult. Meteorological rockets were seen as a solution to collect data from the upper layers of the atmosphere.

Establishment of Thumba Equatorial Rocket Launching Station (TERLS)

To conduct rocket experiments, India established the Thumba Equatorial Rocket Launching Station (TERLS) near Thiruvananthapuram, Kerala. Its location near the equator made it ideal for atmospheric and space research. TERLS soon became a hub for international scientific cooperation and experimentation.
