Starting as a young research scholar at the Physical Research Laboratory, Ahmedabad, in 1963, K. Kasturirangan’s career in the Indian space sector spanned nearly four decades as he occupied the top position of Chairman of the Indian Space Research Organisation (ISRO) in the 1990s.

During his tenure in ISRO as the head of various centres and project director of landmark missions, Dr. Kasturirangan mentored many future space leaders who went on to occupy the top echelons of the Indian space sector.
Inspiring figure
“As a young engineer in ISRO, I had the opportunity to interact and learn from him. I regularly used to seek his advice on various issues even after I assumed the role of ISRO Chairman, and he was very forthcoming and helpful in sharing his views,” former ISRO Chairman K. Sivan told The Hindu.

He added that Dr. Kasturirangan’s death is a loss not just for the space sector but the entire country, considering the several posts he had held. “After retiring from ISRO, he served in various positions as the Rajya Sabha member and the Planning Commission member. He also headed several crucial committees like the ones on the Western Ghats and the National Education Policy. Hence, his passing away is a loss not just for the space fraternity but the nation as a whole.”

In his post on X, another former ISRO Chairman S. Somanath said, “He had a profound influence on all of us in ISRO. It leaves a vacuum in the community of technocrats and thinkers whose voice is heard by all.”
Several missions
In Dr. Kasturirangan’s tenure, ISRO had a near-100% success for space by way of 29 successful missions (of satellites and launch vehicles), including four commercial/foreign satellites launched through Antrix.
He also held various important roles in international bodies including vice-president (Scientific Affairs) of the International Academy of Astronautics (2003-2005), member of the International Academy of Astronautics Sub-Committee on Mars Exploration (1992-93), and chairman of COSPAR Panel on Space Research in Developing Countries (1994-2000).
In total, he published 257 papers in national and international journals/symposia and edited nine books.
