India is mourning the passing of a true pioneer in space science, Dr. Eknath Vasant Chitnis, who peacefully departed at the remarkable age of 100. Dr. Chitnis passed away on Wednesday, October 22, 2025, at his home in Pune after a brief period of illness, succumbing to a heart attack in the morning, his family confirmed.
A distinguished recipient of the Padma Bhushan, Dr. Chitnis was a towering figure in the foundational years of India’s space research. His work was pivotal in the evolution of the Indian National Committee for Space Research (INCOSPAR) into what we know today as the Indian Space Research Organisation (ISRO).
Among his many significant contributions, Dr. Chitnis was instrumental in identifying and selecting Thumba in Kerala as the prime location for India’s inaugural rocket launch. His leadership continued to shape the nation’s space endeavors, as he served with distinction as the second director of ISRO’s Space Applications Centre (SAC) in Ahmedabad from 1981 to 1985.
He was also one of the last remaining direct colleagues of Dr. Vikram Sarabhai, revered as the father of India’s space program, underscoring his deep historical connection to the roots of Indian space exploration. Furthermore, Dr. Chitnis is fondly remembered for his mentorship and guidance to many budding scientists, including none other than the future President of India, Dr. APJ Abdul Kalam.
Dr. Chitnis leaves behind a profound legacy and is survived by his son Dr. Chetan Chitnis, daughter-in-law Amika, and his granddaughters Tarini and Chandini.
