What is ISRO?

ISRO is an Indian space agency funded by the government of India. The ISRO is the acronym of the Indian Space Research Organization. The vision of ISRO is to “Harness space technology for national development while pursuing space science research and planetary exploration”.

Establishment of the ISRO:

The Indian Space Research Organization came into effect on August 15th, 1969.

ISRO Space Stations:

ISRO has two space stations that are used to send satellites into space by using the launch vehicles.

1. Satish Dhawan space center, Sriharikota, Andhra Pradesh, India.

2. Vikram Sarabhai space center, Thiruvananthapuram, Kerala, India.

ISRO Launch Vehicles:

The first launch vehicle of the ISRO was SLV-3 (Satellite Launch Vehicle-3). It is a small lift launch vehicle.

After SLV-3, ISRO developed PSLV (Polar Satellite Launch Vehicle) and then GSLV (Geosynchronous Satellite Launch Vehicle).

On 5th June 2017, ISRO launches GSLV-MKIII (Geosynchronous Satellite Launch Vehicle Mark-III), and it is the heaviest rocket of ISRO till now.

ISRO Achievements:

The first satellite built by the ISRO was Aryabhata.

The first satellite launched by the Indian made launch vehicle was Rohini in 1980.

On 22nd October 2008, ISRO sent a lunar orbiter Chandrayaan-1.

On 5th November 2013, ISRO sent a Mars orbiter Mangalyaan.

On 18th June 2016, ISRO launched 20 satellites by using a single launch vehicle.

On 15th February 2017, ISRO launched 104 satellites by using a single launch vehicle PSLV-C37.

On 22nd July 2019, ISRO sent its second lunar mission Chandrayaan-2.

The ISRO is expected to send a human space flight in 2022 with 4 astronauts.


The headquarters of ISRO is situated in Bengaluru, India.

Applications of satellites:

The satellites are used for telecommunication, resource management, natural disaster forecasting, radio networking, weather forecasting. The satellites are also used by the Army, Airforce, and Navy to navigate the route of aircraft, missiles, and radars, etc.

Indian Space Programme:

The Indian space program was initiated in 2007, and it is under development. In 2019, the Prime minister of India Shri Narendra Modi announced that the ISRO is expected to send a human space mission in 2022, and the mission name will be Gaganyaan. The GAGAN is the acronym of "GPS Aided GEO Augmented Navigation", and Yaan means an Aircraft. Currently, four astronauts are under training in Russia, and also before sending a human spacecraft in space, ISRO will send an unmanned space flight to check the safety of the astronauts. The Indian space agency has the capacity and technology to send a human flight in space.
