The Indian Space Research Organisation (ISRO) is the primary space agency of the Indian government. ISRO is amongst the six largest government space agencies in the world, along with USA's NASA, Russia's RKA, Europe's ESA, China's CNSA and Japan's JAXA. Its primary objective is to advance space technology and use its applications for national benefit.
Established in 1969, ISRO superseded the erstwhile Indian National Committee for Space Research (INCOSPAR). Headquartered inBangalore, ISRO is under the administrative control of the Department of Space, Government of India.
ISRO has achieved numerous milestones since its establishment. India's first satellite, Aryabhata, was built by ISRO and launched by the Soviet Union in 1975. Rohini, the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3, was launched in 1980. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for putting satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites, earth observation satellites, and, in 2008, Chandrayaan-1, India's first mission to theMoon.
Over the years, ISRO has conducted a variety of operations for both Indian and foreign clients. ISRO's satellite launch capability is mostly provided by indigenous launch vehicles and launch sites. In 2008, ISRO successfully launched its first lunar probe,Chandrayaan-1, while future plans include indigenous development of GSLV, manned space missions, further lunar exploration,mars exploration and interplanetary probes. ISRO has several field installations as assets, and cooperates with the international community as a part of several bilateral and multilateral agreements.
