Indian Space Research Organisation
ISRO built India's first satellite, Aryabhata, which was launched by the Soviet Union on 19April 1975. It was named after the mathematician Aryabhata. In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and earth observation satellites. Satellite navigation systems like GAGAN and IRNSS have been deployed. In January 2014, ISRO used an indigenous cryogenic engine in a GSLV-D5 launch of the GSAT-14.
Udupi Ramachandra Rao
Rao started his career as a cosmic ray scientist, and worked under Dr. Vikram Sarabhai, which he continued at MIT. In association with the JPL 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.
