The concept of "Achievements of Indians in science & technology" represents a continuous national commitment to scientific and technological self-reliance, spanning from ancient foundations to modern institutional programs. The historical roots of this tradition include the 5th-century astronomer Aryabhata, whose work, the Aryabhatiya, approximated the value of pi to 3.1416 and proposed that the Earth rotates on its axis. The modern institutional phase began with the establishment of the nuclear program by Homi J. Bhabha, who founded the Tata Institute of Fundamental Research (TIFR) in 1945 and the Atomic Energy Establishment, Trombay (AEET) in January 1954. This led to the first nuclear test, Pokhran-I, in 1974.
The space program, founded by Vikram Sarabhai, was formalized with the creation of the Indian Space Research Organisation (ISRO) on August 15, 1969, to harness space technology for national development. ISRO's mechanism relies on indigenous launch vehicles like the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) to deploy satellites for communication and remote sensing. The nuclear program, centered at the Bhabha Atomic Research Centre (BARC), operates on a three-stage plan to utilize India's abundant Thorium reserves. Recent milestones have significantly advanced India's global standing: ISRO's Chandrayaan-3 mission in 2023 achieved a historic soft landing near the lunar south pole, and the launch of Aditya-L1 in 2024 marked India's first solar observatory.
