The achievements of ISRO make every Indian proud of their pioneering journey in space exploration. But the foundation of this remarkable story began earlier in the 1960s era.

In 1962, the Indian National Committee for Space Research (INCOSPAR) laid the groundwork for India’s space program. It set the stage for what would later become the Indian Space Research Organisation (ISRO), officially founded in 1969. ISRO took on the ambitious goal of harnessing space technology for national development, transforming the dreams of a young nation into reality.

Since its inception, the achievements of ISRO have been nothing short of extraordinary. From launching satellites that revolutionize communication and remote sensing to mastering indigenous technologies like the cryogenic propulsion system, ISRO has not only advanced India’s space capabilities but also established itself as a global leader. Each mission has expanded the reach of science and technology, from agriculture and telecommunication to disaster management.

ISRO’s mission to harness space technology for the betterment of society continues to drive its innovations. The agency’s breakthroughs extend beyond cutting-edge technology, inspiring future generations through collaborations with academic institutions and initiatives that promote space research.
