The main objective of the Indian Space Research Organization (ISRO) is to use space technology and its applications to perform various national responsibilities. The organization is also responsible for cost-effective technologies for space activities.

The economic progress of India has made its space program more active and visible as the nation is looking for greater self-reliance in space technology. It also aims to improve international cooperation in space exploration.

The India Space Research Organization (ISRO) is also responsible for;
Improving mass communication and education with the use of satellites.
For developing indigenous satellites and satellite launch vehicles.
Managing and surveying natural resources via remote sensing technology, environmental monitoring, and meteorological forecasting.


The first Indian satellite, Aryabhata was constructed by the Indian Space Research Organization (ISRO) and it was launched by the Soviet Union on 19 April 1975. The satellite was named after the famous Indian mathematician, Aryabhata. The ISRO was also able to launch Rohini which became the first satellite to be sent into orbit by an Indian-made launch vehicle in 1980. The launch vehicle was known as SLV-3.

The organization also designed and built two more rockets named the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits and the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits. These rockets have been used to launch several Earth observation satellites and communication satellites. It has also been used to launch satellite navigation systems like IRNSS and GAGAN. The organization was able to use an indigenous cryogenic engine in a GSLV-D5 launch of the GSAT-14 in January 2014.

India was able to successfully launch as many as eleven satellites in 2008 and proceeded to become the first country to launch ten satellites on one rocket. Nine of these satellites are from other countries. The two main satellite systems that have been put into operation by the Indian Space Research Organization (ISRO) are the Indian Remote Sensing (IRS) satellites for management of natural resources and the Indian National Satellites (INSAT) for communication services.

In the past 5 decades, the Indian Space Research Organization (ISRO) has been able to successfully launch more than 80 satellites for different scientific and technological purposes like direct to home services, disaster warning, remote sensing, mobile communication, radio networking, telecommunication, telemedicine, and meteorological observations.

On October 22, 2008, the organization was able to successfully launch a lunar orbiter, Chandrayaan-1 to space. On November 5 3013, the organization was also able to successfully send a Mars orbiter, Mars Orbiter Mission to space and it reached Mars orbit on September 24, 2014. This is what made India the first country to succeed on its first attempt to Mars. The ISRO was also the first space agency in Asia and the fourth in the world to reach Mars orbit.

The Indian Space Research Organization (ISRO) also set another record on June 18, 2016, by being the first space agency to successfully launch twenty satellites to space in one payload. One of these satellites was from Google. The organization also creates a world record by launching one hundred and four satellites to space in a single rocket (PSLV-C37) on February 15, 2017.

On June 5, 2017, the ISRO launched the Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) which was its heaviest rocket. The rocket carried the communication satellite GSAT-19 into Earth’s orbit. The organization is now capable of sending a 4-ton heavy satellite into Geostationary Transfer Orbit (GTO).

The Indian Space Research Organization (ISRO) has also revealed some of its future plans to the public. These plans include the development of a reusable launch vehicle, Human spaceflight, solar spacecraft mission, Small Satellite Launch Vehicle, Unified Launch Vehicle and controlled soft lunar landing, interplanetary probes.

The Indian Space Research Organization (ISRO) has also signed inter-governmental space cooperation agreements with other countries like Chile, the United Kingdom, Brazil, Ukraine, Russia, the United States, France, India, Pakistan, Italy, Germany, and some other countries. The governmental space cooperation agreements have resulted in significant achievements.
