The Indian Space Research Organisation is India’s national space agency and one of the most respected space organisations in the world. The full form of ISRO is Indian Space Research Organisation. The ISRO was established in 1969, and since then, it has played an important role in shaping India’s journey in space science and technology. The ISRO was founded under the guidance of scientist Vikram Sarabhai, who believed that space technology could help solve real problems faced by people in developing countries. The organisation started with limited resources and small experiments, but eventually ISRO built strong capabilities in satellite development, launch vehicles and deep-space exploration.
ISRO is known for achieving big milestones at remarkably low costs. It is responsible for launching communication and weather satellites for exploring the Moon and Mars. ISRO has made India proud on the global stage through various successful missions, such as the Chandrayaan series, Mangalyaan and AstroSat. ISRO is renowned for innovation, dedication and scientific excellence and continues to push the boundaries of space exploration while contributing to communication, navigation, disaster management and national development.
What is Indian Space Research Organisation (ISRO)?
Established in 1969 under the leadership of Dr Vikram Sarabhai, ISRO stands for Indian Space Research Organisation. ISRO focused on launch vehicle development, space science explorations, satellite programs and global outreach through various successful missions. Headquartered in Bengaluru, ISRO aims at utilizing space technology for the development of the nation. ISRO operates under the Department of Space and is one of the world’s top six government space agencies, specialising in satellite development, launch vehicles, and space exploration. ISRO is one of the few agencies to achieve soft landing capabilities on the moon. From January 14, 2025, Dr V. Narayanan is the current Chairman of the Indian Space Research Organisation (ISRO) and Secretary to the Government of India, Department of Space.
Key Aspects of Indian Space Research Organisation (ISRO)
The Indian Space Research Organisation is India’s premier space agency focused on launch vehicle development, space science explorations, satellite programs and global outreach. Let’s take a look at the key aspects of the Indian Space Research Organisation: -
1. Launch Vehicle Development
ISRO specializes in designing launch vehicles such as the Polar Satellite Launch Vehicle, Geosynchronous Satellite Launch Vehicle and LVM3. The space organisation ensures independent access to space.
2. Space Science and Exploration
ISRO regularly conducts high-profile missions, such as Chandrayaan-1 in search of water on the Moon, along with Mars Orbiter Mission known as Mangalyaan, Shukrayaan-1 and Chandrayaan-3 for lunar exploration.
3. Satellite Programs
ISRO operates the Indian National Satellite System for telecommunication and weather forecasting. It also manages Indian Remote Sensing satellites for natural resource management and advanced communication satellites enabling broadband services, digital broadcasting and telephony.
4. Indigenous Navigation System
ISRO developed the Indian Regional Navigation Satellite System, branded as NavIC, to provide navigation services over India and surrounding regions. It is India’s independent regional satellite navigation system.
5. Commercialization and Global Outreach
Through its commercial zone, known as NewSpace India Limited, ISRO provides launch services to global clients while partnering with international agencies like NASA and ESA for joint space missions.
Major Centres of ISRO
The Major centres of ISRO include the Vikram Sarabhai Space Centre (VSSC) (Thiruvananthapuram) for launch vehicles, Satish Dhawan Space Centre (SDSC) SHAR (Sriharikota) for launches, and U R Rao Satellite Centre (URSC) (Bengaluru) for satellite design. Other key centers are the Liquid Propulsion Systems Centre (LPSC) (Valiamala/Bengaluru) and Space Applications Centre (SAC) (Ahmedabad).

History of Indian Space Research Organisation (ISRO)
The Indian Space Research Organisation was established on 15 August 1969, replacing the Indian National Committee for Space Research. ISRO was set up under the leadership of Dr Vikram Sarabhai, who is popularly known as the ‘founding father’ of India's space program. Let’s take a look at the history of the Indian Space Research Organisation (ISRO):-
The Formative Years (1960s)
ISRO was established in 1969 by Dr Vikram Sarabhai. During the 1960s, ISRO focused on building infrastructure and launching sounding rockets. The Thumba Equatorial Rocket Launching Station was set up in 1963, and on 19 April 1975, India launched its first satellite, Aryabhata, using a Soviet rocket.
Experimental and Building Phase (1980s)
This era focused on gaining technical space independence and demonstrating end-to-end capabilities. Shortly, the Department of Space and the national space day were created, which brought ISRO into its full glory. ISRO achieved a major milestone with the successful launch of the Rohini satellite using India's own SLV-3 launcher.
Operational Phase and Workhouse Rockets (1990s)
ISRO transitioned to building space operational systems for international use. The Polar Satellite Launch Vehicle became operational during the 1990s. ISRO eventually earned the nickname ‘ISRO's workhorse’ for its high reliability. During this phase, the first successful launch of the Geosynchronous Satellite Launch Vehicle took place.
Modern Era and Deep Space Exploration (2010-Present)
ISRO shifted toward planetary exploration and heavy space mission capabilities. ISRO successfully showcased in orbit space anchor through the SpaDeX mission and joined an elite group of four nations with this technology. The Mars Orbiter Mission was launched in 2014, making India the first nation to reach Mars orbit on its first attempt.
Missions and Achievements of Indian Space Research Organisation (ISRO)
The Indian Space Research Organisation is the national space agency and is popular for achieving major milestones in lunar exploration, solar studies and commercial launch services. It has conducted successful Chandrayaan-3 lunar south pole landing, the Mars Orbiter Mission, Aditya-L1 solar mission and the development of the reliable PSLV launch vehicle. Let’s take a look at the missions and achievements of ISRO: -
1. Chandrayan Series
ISRO launched Chandrayaan 1 in 2008 and discovered lunar water molecules on the moon. Also, ISRO launched Chandrayaan 3 in 2023 which made India the first nation to soft-land near the moon’s south pole.
2. Mangalyan 1
ISRO launched Mangalyan 1 in 2013, making India the first Asian country and first in the world to reach Mars orbit on its first attempt. It captured extensive images of Mars, mapped the surface, and discovered suprathermal argon-40 in the martian exosphere.
3. Aditya L-1
Aditya-L1 is the first space-based Indian observatory dedicated to studying the Sun. The mission enabled a better understanding of solar dynamics and space weather, which provided important data on how coronal magnetic fields evolve.
4. AstroSat
AstroSat is India’s first dedicated multi-wavelength space observatory, which was launched by ISRO in 2015. As of now, it has completed 10 years in orbit, and it is often known as a mini-Hubble telescope. AstroSat can study cosmic sources and is capable of covering energy bands from ultraviolet rays.
5. SpaDex 1
The SpaDex 1 mission was launched by ISRO on December 30, 2024, and it aimed to test two spacecraft in low Earth orbit important for future space station operations and satellite servicing. The Spadex Mission had two satellite launches, which used AI-driven algorithms.
Upcoming and Future Missions of ISRO
ISRO's upcoming ambitious missions are human spaceflight known as Gaganyaan, lunar sample return known as Chandrayaan 4, Mars exploration known as Mangalyaan-2 and establishing an indigenous space station known as Bharatiya Antariksh Station by 2035. Let’s take a look at the upcoming and future missions of ISRO: -
- Gaganyaan Program: Gaganyaan Program is India's first human spaceflight mission aiming to send astronauts to Low Earth Orbit. It includes three uncrewed precursor missions along with a crewed flight in 2027.
- NISAR: NISAR satellite is a NASA-ISRO synthetic aperture radar, which is a joint mission for high-resolution earth observation using advanced radar.
- Chandrayan 4: It is a lunar sample return mission aiming to collect samples from the Moon's surface and return them to Earth.
- Lunar Polar Exploration Mission: It is a joint ISRO-JAXA mission targeting the lunar south pole to explore water ice and test landing technology.
- Mangalyaan 2: It is the Mars Orbiter Mission 2, which will include an orbiter and a lander to conduct scientific experiments on the surface of Mars.
