The Indian Space Research Organisation (ISRO; ) is the national space agency of India, headquartered in Bangalore. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well. ISRO is India's primary agency for performing tasks related to space-based applications, space exploration and the development of related technologies. It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites. The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, on the urging of scientist Vikram Sarabhai, recognising the need in space research. INCOSPAR grew and became ISRO in 1969, within DAE. In 1972, the government of India set up a Space Commission and DOS, bringing ISRO under it. The establishment of ISRO thus institutionalised space research activities in India. It since then has been managed by DOS, which governs various other institutions in India in the domain of astronomy and space technology. ISRO built India's first satellite, Aryabhata, which was launched by the Soviet Union in 1975. In 1980, ISRO launched satellite RS-1 onboard its own SLV-3, making India the seventh country to be capable of undertaking orbital launches. SLV-3 was followed by ASLV, which was subsequently succeeded by development of many medium-lift launch vehicles, rocket engines, satellite systems and networks enabling the agency to launch hundreds of domestic and foreign satellites and various deep space missions for space exploration. ISRO has the world's largest constellation of remote-sensing satellites and operates the GAGAN and NAVIC satellite navigation systems. It has sent two missions to the Moon and one to Mars. Goals in near future include expanding satellites fleet, landing a rover on Moon, sending humans into space, development of a semi-cryogenic engine, sending more uncrewed missions to the Moon, Mars, Venus and Sun and deployment of more space telescopes in orbit to observe cosmic phenomena and outerspace beyond the Solar System. Long-term plans include development of reusable launchers, heavy and super heavy launch vehicles, deploying a space station, sending exploration missions to external planets like Jupiter, Uranus, Neptune and asteroids and crewed missions to moons and planets. ISRO's programs have played a significant role in the socio-economic development of India
