Kasturirangan dedicated over thirty-five years of his career to the Indian Space Research Organisation (ISRO), leading the agency from 1994 to 2003 during a challenging period marked by various international restrictions, particularly concerning access to cryogenic technology. These limitations intensified following India’s nuclear tests in 1998, which further complicated the landscape for the space agency. Under Kasturirangan’s guidance, ISRO initiated a journey towards self-sufficiency, laying the groundwork for significant missions such as Chandrayaan. Following his tenure at ISRO, he transitioned into a prominent political role as a member of the Rajya Sabha and later contributed to the Planning Commission. His expertise was sought in various advisory roles, where he chaired or participated in committees addressing critical issues spanning higher education, technology, and environmental concerns. Prime Minister Narendra Modi expressed profound sorrow at the news of Dr. K. Kasturirangan’s passing, highlighting his monumental impact on India’s scientific and educational landscape. Modi praised Kasturirangan’s visionary leadership and unwavering commitment to advancing the nation’s space program, which garnered international acclaim and facilitated ambitious satellite launches while fostering a culture of innovation.
