History Of Indian Space Research Organisation (ISRO)

ISRO has earned its place among the world's elite space agencies by successfully demonstrating its unique and cost-effective technology over the years. India's first artificial satellite Aryabhata, was built by ISRO and launched on April 19, 1975 with the support of the Soviet Union. 1980 saw the launch of  Rohini, the first satellite successfully launched into orbit by an Indian-made SLV-3 rocket. Further efforts then led to the development of two more missiles by ISRO.

PSLV (Polar Satellite Launch Vehicle) for launching satellites into polar orbit GSLV (Geosynchronous Satellite Launch Vehicle) for launching satellites into geostationary orbit. Both rockets have successfully launched several earth observation and communications satellites for India and other countries. 

What Is ISRO? 

Indian Space Agency established in 1969 to develop an independent Indian space program. The company is headquartered in Bangalore (formerly Bangalore). The CEO of ISRO is the Chairman, Chairman of the Government of India's Space Commission and Secretary of the Ministry of Space.

The Indian Space Research Organization (ISRO) operates through a nationwide network of centres. Sensors and payloads are being developed at the Space Applications Center in Ahmedabad. The satellites are designed, developed, assembled and tested at UR Rao Satellite Center (formerly ISRO Satellite Center) in Bangalore. 

The launcher is being developed at the Vikram Sarabhai Space Center in Thiruvananthapuram. The launch will take place at the Satish Dhawan Space Center on Sriharikota Island near Chennai. The main control facilities for maintaining geostationary satellite stations are located in Hassan and Bhopal. The remote sensing data reception and processing facility is located at the National Remote Sensing Centre, Hyderabad. ISRO's trading arm is Antrix Corporation, headquartered in Bangalore.  

ISRO Missions 

ISRO's first satellite, Aryabhata, was launched by the Soviet Union on April 19, 1975. Rohini was the first satellite launched into orbit by an Indian-made rocket (Satellite Launch Vehicle 3) and was launched on July 18, 1980 Indian Remote Sensing (IRS) satellites for communications, television broadcasting, meteorology and disaster warnings, and resource monitoring and management. 

The first of his INSATs was launched in 1988, and the program expanded to include geostationary satellites called his GSATs. The first of his IRS satellites was also launched in 1988, and the program has developed more specialised satellites such as the Radar Imaging Satellite-1 (RISAT-1, launched in 2012) and the Argos and Altika satellites (SARAL, launched in 2013).  Joint Indian-French mission to measure sea wave heights. Since then, ISRO has developed three more missiles.

The Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits, the Geostationary Space Launch Vehicle (GSLV) for launching satellites into geosynchronous orbits, and a heavyweight version of the GSLV called LVM3. These rockets launched communications and earth observation satellites, as well as missions to the Moon (Chandrayaan-1, 2008; Chandrayaan-2, 2019) and Mars (Mars Orbiter Mission, 2013). ISRO plans to put astronauts into orbit on its Gaganyaan spacecraft in 2024.  

ISRO Achievements 

Indian Space Research Organization was established on 15th August 1969 for the purpose of 'Manav jati ki seva mein Antrariksa Prudyogiki'. The head office is located in Bangalore city. First Prime Minister Jawaharlal Nehru and his aide, academic Vikram Sarabhai. ISRO is constantly updating itself with new advanced technologies and has a strong position in the global space sector. ISRO sets new records every year.

 Great figures (APJ Abdul Kalam, Dr. K. Radhakrishnan, etc  have contributed greatly to ISRO's reorientation and success. Specifically, APJ Abdul Kalam created the story with his ISRO. Kalam was transferred to the Indian Space Research Organization (ISRO) where in July 1980 he successfully launched the Rohini satellite into low earth orbit. I was. He said that joining ISRO was the greatest achievement of his life and that he discovered himself when he started working on the SLV project. From 1970 to 1990 he worked on the development of the Callum Polar SLV and He SLV III projects, both of which were successful. 

  • Aryabhata, 1975 -  ISRO built India's first artificial satellite, Aryabhata, launched by the Soviet Union on April 19, 1975. It is named after the mathematician Aryabhata.  

  • Rohini 1980- The first satellite to be placed in orbit and It was a 35 kg (77 lb) spin-stabilised experimental satellite that consumed 3 W of power and was launched by SDSC on August 10, 1980. 

  • Indian National Satellite System 1983- The system, commonly known as Insat, is a satellite network that facilitates communications and broadcasting in the South Asian region. The first satellite in the series  was launched in 1983 and revolutionised the fields of television, radio, telecommunications and meteorology in India. Nine satellites are in operation. 

  • Polar Satellite Launch Vehicle 1993- The organisation  has developed two rockets, the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geostationary Satellite Launch Vehicle (GSLV) for placing satellites in geostationary orbit.  

  • Chandrayan 2008- India's first unmanned lunar rover was launched almost a decade ago and was a milestone in India's space missions. ISRO has joined an elite roster of just six space organisations to send an orbiter to the moon.  

  • Mangalyaan 2014- India joined the exclusive global club when it successfully launched a mission to orbit Mars at a budget that was at least a tenth the size of similar projects in the United States. The Rs 450 crore project revolved around Mars and aimed to collect data on the Martian atmosphere and mineral composition. 

  • 104 Satellite 2017- Recently, ISRO made new world history with the successful launch of record-breaking satellite 104 in a single rocket from the Sriharikota Cosmodrome . This is the largest number of satellites ever launched in a single mission. The space agency's proven workhorse, his PSLV-C37 polar satellite launcher, is his 39th mission from Sriharikota Space Center with 104 satellites, 101 of which will serve international customers. ISRO is the best organisation in India with all the great and hardworking scientists doing their best. These scientists bring integrity, responsibility and dedication to their work and give ISRO new direction.   


There is no doubt that ISRO is truly the pride of India. Moreover, it has enhanced India's world reputation as a country of scientific thought and development. Hopefully, ISRO will continue its noble mission of exploring space and technology in the future and in the upcoming future also ISRO will again make India proud and there will be one day in future when ISRO  will become number one space agency in the world.
