ISRO’s Space Research Programme and ANTRIX Corporation

Science & Technology › Space Technology and ISRO · Topic 12.3

The Indian Space Research Organisation, ISRO, is the space agency of India, set up on 15 August 1969 from the earlier Indian National Committee for Space Research founded in 1962 under Vikram Sarabhai, and it works under the Department of Space, which reports directly to the Prime Minister. ISRO is headquartered in Bengaluru, and its programme covers launch vehicles, communication, Earth observation, navigation, space science and human spaceflight. Antrix Corporation Limited, formed in 1992, is its commercial and marketing arm, which sells satellite services, launches and products abroad. Later, NewSpace India Limited was created in 2019 for commercial production, and the Indian National Space Promotion and Authorisation Centre, IN-SPACe, was set up in 2020 to allow private firms to take part.

Where Does It Fit?

This topic follows the launch vehicle categories. After rockets, the macro presents the organisation that builds and flies them and the structure of the Indian space programme. Previous topic: Categories of Launch Vehicles and Their Uses. Next topic: Satellite Systems: INSAT, GSAT, IRS (Remote Sensing).

How Is the Indian Space Programme Organised?

Body	Role
INCOSPAR	Indian National Committee for Space Research, set up in 1962 under the Department of Atomic Energy with Vikram Sarabhai as chairman
ISRO	Formed on 15 August 1969 as the research agency of the programme
Space Commission and Department of Space	Established in 1972. The Prime Minister is in charge of the Department. The Space Commission formulates policy
Antrix Corporation	Set up in 1992 as the marketing arm of ISRO for products, services and satellite launches. Government owned company under the Department of Space
NewSpace India Limited (NSIL)	Created in March 2019 as a public sector company to take up production of launch vehicles and satellites with industry, and to commercialise space products
IN-SPACe	Set up in June 2020 as a single window agency to authorise, promote and regulate private space activity
Indian Space Policy 2023	Defines roles: ISRO for research and advanced technology, NSIL for commercial work, IN-SPACe for authorisation

Which Centres and Milestones Are Important?

Vikram Sarabhai Space Centre: Thiruvananthapuram, for launch vehicles
Satish Dhawan Space Centre: Sriharikota, India’s spaceport
U R Rao Satellite Centre: Bengaluru, for satellites
Space Applications Centre: Ahmedabad, for communication and Earth observation payloads
Liquid Propulsion Systems Centre and ISRO Propulsion Complex: for liquid and cryogenic engines

What Else Should You Remember?

First rocket: a sounding rocket was launched from Thumba on 21 November 1963, with parts carried on a bicycle and a bullock cart
Aryabhata: India’s first satellite, launched on 19 April 1975 from the Soviet Union
SLV-3: successfully put the Rohini satellite into orbit in July 1980, making India the sixth country to do so
APPLE and Bhaskara: early experimental satellites for communication and Earth observation
INSAT and IRS: the INSAT series began in 1983 and the Indian Remote Sensing series in 1988
Chandrayaan-1 and Mars Orbiter Mission: India’s first Moon mission was in 2008 and the first Mars mission in 2013, as in Chandrayaan Missions (Chandrayaan-I, II, III) and the Mars Orbiter Mission
Chandrayaan-3: soft-landed near the Moon’s south pole on 23 August 2023, now observed as National Space Day
Launches for other countries: ISRO has launched hundreds of foreign satellites for dozens of countries on a commercial basis through Antrix and NSIL. Check the latest figure
Chairman: the ISRO chairman is also the Secretary of the Department of Space, and V Narayanan took charge in January 2025
Space reforms: reforms from 2020 opened launch, satellite and ground segment activities to private firms
Space budget: India spends a small share of its budget on space compared with the United States or China, but gets cost effective missions
Gaganyaan: the human spaceflight programme aims to send Indian astronauts to low Earth orbit, with first uncrewed missions planned before a crewed flight
Technology transfer: ISRO transfers technologies to industry, and the Government has asked industry to take over production of PSLV through a consortium, as part of NSIL work
Public outreach: ISRO runs Space Technology Incubation Centres at universities and encourages students through the Indian Institute of Space Science and Technology

Why Does It Matter for the Exam?

Dates: 1962, 1969, 1972, 1992, 2019, 2020
Bodies: ISRO, Antrix, NSIL, IN-SPACe and their roles
Centres: which centre does what
Current affairs link: space policy and private sector reforms
Common errors: confusing NSIL with Antrix, or IN-SPACe with ISRO

As an analytical point, the space sector is shifting from a government monopoly to a shared system where ISRO focuses on research and strategic missions while industry handles production and services.
