Dr. K. Kasturirangan, the former chairman of the Indian Space Research Organisation (ISRO), passed away on April 25, 2025, in Bengaluru, leaving behind a monumental legacy in the field of space science and technology. His death marks the loss of one of India’s most influential scientists, whose contributions were instrumental in placing the country at the forefront of global space exploration.
Dr. Kasturirangan served as the ISRO chairman from 1994 to 2003, a period that witnessed some of the most significant milestones in India’s space journey. He played a key role in transforming ISRO into one of the world’s most respected space agencies. His visionary leadership propelled India to new heights, particularly in the areas of satellite development, space missions, and space policy.
Dr. Kasturirangan’s Pivotal Role in ISRO’s Achievements
Under Dr. Kasturirangan’s leadership, ISRO achieved remarkable success, with several landmark missions that changed the trajectory of India’s space program. One of his most notable achievements was overseeing India’s first mission to the Moon, Chandrayaan-1, which not only marked India’s entry into lunar exploration but also provided critical data that confirmed the presence of water molecules on the Moon’s surface.
In addition to his role in Chandrayaan-1, Dr. Kasturirangan was a driving force behind the development of the Polar Satellite Launch Vehicle (PSLV), which became one of ISRO’s most successful and reliable launch vehicles. Under his guidance, ISRO also succeeded in launching multiple satellites on a single rocket, a feat that demonstrated India’s technological prowess and cost-effective space capabilities.
His vision extended beyond technical achievements; he advocated for the use of space technology for societal good. Under his leadership, India made strides in using satellite-based remote sensing for applications in agriculture, disaster management, and environmental monitoring. The Indian Remote Sensing (IRS) satellites were a direct result of Dr. Kasturirangan’s foresight, and they continue to play a crucial role in India’s agricultural and environmental monitoring efforts.
