Udupi Ramachandra Rao was an Indian space scientist and former chairman of ISRO. He was also the Chairman of the Governing Council of the Physical Research Laboratory at Ahmedabad and Nehru Planetarium at Bengaluru and chancellor of the Indian Institute for Space Science and Technology (IIST) at Thiruvananthapuram. He is known as "The Satellite Man of India". He pioneered India's first satellite launch Aryabhata in 1975.
U. R. Rao was born into a Madhwa Brahmin Hindu family at Adamaru in the state of Karnataka. His parents were Lakshminarayana Acharya and Krishnaveni Amma. He had his primary education at Adamaru. He completed his secondary education from Christian High School, Udupi. He completed his B.Sc. from Government Arts and Science College (now in Andhra Pradesh), M.Sc. from Banaras Hindu University and Ph.D. at Physical Research Laboratory Ahemdabad under the guidance of Vikram Sarabhai.Prof. U. R. Rao was married to Mrs. Yashoda Rao.
Rao started his career as a cosmic ray scientist and worked under Vikram Sarabhai, which he continued at MIT. In association with the Jet Propulsion Laboratory group, he was the first to establish the continuous nature of the solar wind and its effect on geomagnetism using Mariner 2 observations. Rao's experiments on a number of Pioneer and Explorer spacecraft led to a complete understanding of the solar cosmic-ray phenomena and the electromagnetic state of the interplanetary space. Convinced of the imperative need to use space technology for rapid development, Rao undertook the responsibility for the establishment of satellite technology in India in 1972. Under his guidance, beginning with the first Indian satellite "Aryabhata" in 1975, over 18 satellites including Bhaskara, APPLE, Rohini, INSAT-1 and INSAT-2 series of multipurpose satellites and the IRS-1A and IRS-1B remote sensing satellites were designed, fabricated and launched for providing communication, remote sensing, and meteorological services.
