ISRO: Overview, History, Centres, Eligibility, and its Significance

With the vision of harnessing space technology for national development, the Indian Space Research Organisation (ISRO) was established on 15 august 1969. Vikram Sarabhai, who dreamt of space technology work for the nation’s development, is known as the father of ISRO. Its headquarters is in Bangalore.

India took its first step into space exploration with the establishment of the Indian National Committee for Space Research (INCOSPAR) by the government of India under the department of atomic energy in 1962. Later Vikram Ambalal Sarabhai demanded to set up a separate research organization, and INCOSPAR became ISRO in 1969. It is working under the Department of Space(DOS).


Since then, ISRO has been continuously working on space research and technology for future-readiness, making it the sixth-largest space agency in the world. The main objective of ISRO is to lift launches, and human spaceflight projects, develop reasonable launch vehicles, make semi-cryogenics engines, single-stage to orbit(SSTO), and two-stage to orbit(TSTO), etc.

Historical Achievements of ISRO

  • ISRO launched India’s first satellite “Aryabhatta” named after prominent astronomer in 1975. It was the maiden satellite designed and developed by Indian scientists and launched by the soviet union.
  • In 1980, ISRO successfully tested the SLV3(Satellite Launch Vehicle) from Sriharikota. The SLV3 was successful after two successive failures of SLV in 1979. This achievement made India the sixth member of an exclusive club of space-faring stations.
  • In 1981, ISRO successfully launched its first indigenous communication satellite, “Apple”(Ariane Passenger Payloads Experiment)
  • In 1992, ISRO launched INSAT 2A with the launch weight of 1906 kg for a mission life of seven years. INSAT 2A was the series of INSAT(Indian National Satellite)
  • In 1993, ISRO successfully launched PSLV(Polar Satellite Launch Vehicle), the third generation vehicle of India. Since its launch, PSLV has given 39 consecutive successful launches.
  • In 2001, ISRO achieved a significant milestone by launching India’s first GSLV(Geosynchronous Satellite Launch Vehicle).
  • In 2008, ISRO successfully launched India’s first moon mission, “Chandrayaan-1,” from Satish Dhawan Space Center(SDSC) Sriharikota. It was the maiden launch of a lunar probe under the Chandrayaan program, which used a PSLV-XL rocket.
  • In 2013, ISRO launched its first interplanetary mission on mars, known as Mars Orbiter Mission(MOM).
  • On 24 September 2014, the Mars orbiter mission(MOM) entered Martian orbit in its initial attempt.
  • In 2015, ISRO achieved a milestone in the Indian astronomy mission by launching “AstroSAT.”
  • In 2017, ISRO launched 104 satellites into orbit simultaneously with the help of PSLV-C37.
  • In 2019, ISRO successfully launched India’s second lunar probe mission, “Chandrayaan-2,” from Satish Dhawan Space Center Sriharikota. Chandrayaan-2 consists lunar orbiter, Vikram lander, and Pragyan rover.
  • In 2021, ISRO successfully launched Amazonia-1 and 18 co-passenger satellites from Satish Dhawan Space Center Sriharikota.
