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.

In 1957, the Russian Soviet Union and the United States had set a goal of placing satellites into Earth orbit as part of a worldwide scientific celebration known as the International Geophysical Year. In this endeavor the United States effort was called Project Vanguard. The Soviet Union successfully launched the Sputnik satellite on October 4, 1957, an event followed soon after by a very public and disastrous explosion of a Vanguard rocket. Political pressure forced U.S. politicians to allow a former German rocket scientist, Wernher von Braun, to prepare his Jupiter C rocket for an orbital flight. In the renamed launcher (now called Juno I) the propellant succeeded in launching America’s first satellite, Explorer I, into orbit on January 31, 1958.
