75 Years of Scientific Advancements

India has contributed greatly to the scientific development of mankind. Over 5000 years ago, India created the first herbal medicines in the form of Ayurveda, crucible steel over 2000 years ago, and the creation of the number zero over 1500 years ago, without which many further scientific developments like computers would be impossible. However, India’s developments came to a standstill in the 150 years that it was under British rule, but since independence, the country has bounced back to show its intelligence and might on the world stage.


Every year India generates over 6500 watts of electricity using nuclear energy. Since 1948, when the Indian Atomic Energy Act was passed, India has made many developments in the field of nuclear energy, beginning in 1955, when a small nuclear reactor was built in Trombay for research and training for future power plants. However, the first commercial nuclear power plant in India, the Tarapur Atomic Power Station, was built only in 1969. Since then, India has built multiple reactors and there are currently 22 commercial reactors in India.

On 19th April 1975, India launched its first satellite, the Aryabhatta named after the astronomer of the Gupta period. It was built by the ISRO and launched by the Soviet Union as a part of the Soviet Interkosmos Programme which provided access to space for friendly states. It was built to conduct experiments in X-ray astronomy and solar physics. Although the satellite remained active for only sixty orbits of the planet,the Aryabhatta provided the framework for all future Indian satellites.


In 1971, the United States of America launched the world’s first interplanetary satellite at a staggering $137,000,000. Forty-two years later, India attempted and succeeded in creating its own satellite to orbit Mars, the Mangalyaan. The satellite launched in September 2013 made India the fourth country to launch an interplanetary satellite and the first country to do so on its first attempt. The cost of the Mars Orbiter Mission was an incredibly low $73,000,000, making it the cheapest satellite to ever reach another planet.


In just seventy-five years since India got its independence, it has managed to advance scientifically and in dozens of other fields. The list of its progression will only increase further. ‘Azadi ka Amrit Mahotsav’, celebrating India’s 75 years of independence celebrates so much more, in the form of advancements, successes, and hope for a better India
