Full Form of ISRO (Indian Space Research Organisation)
Full Form of ISRO is Indian Space Research Organisation. The Indian Space Research Organisation is the term of the Indian space agency (ISRO). It was set up as an offshoot of the Indian National Committee for Space Research (INCOSPAR) on August 15, 1969, and has been a part of the Department of Space (DOS) since 1972. Dr. V. Narayanan has been serving as the Chairman of the Indian Space Research Organisation (ISRO) and Secretary of the Department of Space since January 13, 2025, succeeding Dr. S. Somanath.
ISRO was the vision of Dr. Vikram Ambalal Sarabhai, whose dream transformed India into a leading nation in space exploration. From launching Aryabhata, India’s first satellite, in 1975 to achieving historic milestones with Chandrayaan-3 and Aditya-L1, ISRO has made remarkable progress. According to its official records, ISRO has launched 434 foreign satellites, demonstrating India’s growing role in international space cooperation. It also made history with Mangalyaan by becoming the first space agency to successfully reach Mars orbit on its first attempt. More recently, ISRO achieved significant milestones through the SpaDeX space docking mission and the joint NASA–ISRO NISAR satellite mission.
