When we hear the name SPACE, only one organization comes to mind: the Indian Space Research Organization (ISRO). The Indian Space Research Organization (ISRO), located in Bengaluru, is the country's first space agency. ISRO was founded in 1969 with the goal of developing and utilizing space technology for national development while also conducting planetary exploration and space science research. The space research operations began in India in the early 1960s, at a time when satellite applications were still in the experimental stages in the United States. Dr. Vikram Sarabhai, the founding father of India’s space programme, rapidly recognized the benefits of space technologies after the live transmission of the Tokyo Olympic Games across the Pacific by the American satellite ‘Syncom-3’ demonstrated the power of communication satellites. The ISRO has launched various spacecrafts like the Chandrayaan, Astrosat, Microsat, GSAT etc. The Government of India has also approved a regional spaceborne navigation system, which will consist of seven satellites. Out of these, four of them will be placed in geosynchronous inclined orbit of 29° relative to the equatorial plane. Such an arrangement would mean all seven satellites would have continuous radio visibility with Indian control stations.

Name the first dedicated mission launched by ISRO for studying the celestial sources in X-ray, optical and UV spectral bands simultaneously.
