Late Dr. Krishnaswamy Kasturirangan Obituary Message from the Department of Atomic Energy

The Department of Atomic Energy mourns the passing of Dr. Krishnaswamy Kasturirangan, an iconic space scientist, institution builder, and a distinguished member of the Atomic Energy Commission. He passed away on 25 April 2025 at the age of 84.

Dr. Kasturirangan was a visionary leader who shaped the trajectory of India’s space and science ecosystem with unmatched dedication and foresight. As the Chairman of the Indian Space Research Organisation (ISRO), he led the organisation through a golden era of accomplishments. Under his leadership, ISRO witnessed the successful development and deployment of major satellite systems such as INSAT and IRS, as well as the operationalisation of critical launch vehicles including the Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). He was instrumental in defining the Chandrayaan-1 mission, which paved the way for India’s entry into planetary exploration.

An astrophysicist by training, Dr. Kasturirangan made pioneering contributions to high-energy astronomy, with a focus on cosmic X-ray and gamma-ray sources. His scientific acumen was matched by his deep commitment to public service. As a member of the Atomic Energy Commission, he brought to the table his rich expertise and holistic understanding of the strategic scientific landscape of India.

Dr. Kasturirangan also played key roles beyond the scientific realm—as a member of the Rajya Sabha, a former member of the Planning Commission, and the Chairman of the Karnataka Knowledge Commission. Most notably, he chaired the committee responsible for formulating the National Education Policy 2020, laying the foundation for transformative reforms in India’s education system. His leadership of the National Curriculum Framework Steering Committee further reinforced his vision of integrating scientific temper and critical thinking into national development.

Over his distinguished career, Dr. Kasturirangan was honoured with Padma Shri, Padma Bhushan, and Padma Vibhushan, among many other national and international accolades. He was the recipient of honorary doctorates from 27 universities and served as Chancellor of several prestigious institutions.

In Dr. Kasturirangan’s passing, India has lost one of its most luminous scientific minds and a guiding force in science policy and education.

The Department of Atomic Energy extends its heartfelt condolences to his family, colleagues, and the countless individuals inspired by his life and work. His legacy will continue to guide and inspire future generations in the pursuit of science for national progress.
