Humble Beginnings
ISRO was formed in 1969 under the visionary leadership of Dr Vikram Sarabhai, widely regarded as the father of the Indian space programme. In the early days, resources were scarce, and rocket components were famously transported on bicycles and bullock carts to a modest launch site at Thumba, a small fishing village in Kerala. From these unassuming origins grew one of the most respected space agencies in the world, driven by the belief that space technology could directly serve the development needs of a young nation.
Building Self-Reliance
India launched its first satellite, Aryabhata, in 1975 with Soviet assistance, but the goal was always self-reliance. Over the following decades, ISRO developed its own family of launch vehicles. The Polar Satellite Launch Vehicle (PSLV) became its dependable workhorse, launching hundreds of satellites into orbit, including many for other countries. The more powerful Geosynchronous Satellite Launch Vehicle (GSLV) and the heavy-lift LVM3 followed, giving India the capability to launch heavier payloads and ambitious interplanetary missions.
A World Record in Space
In 2017, ISRO captured global attention by launching a record 104 satellites into orbit in a single mission aboard a PSLV rocket — a feat that demonstrated both its technical prowess and its cost-effectiveness. This achievement cemented India’s reputation as a reliable and affordable partner for launching satellites, and its commercial launch services now serve customers around the world.
Chandrayaan: India on the Moon
India’s lunar programme has produced some of its proudest moments. Chandrayaan-1, launched in 2008, helped confirm the presence of water molecules on the Moon, a discovery of major scientific significance. Chandrayaan-2 in 2019 reached lunar orbit, though its lander did not achieve a soft landing. Then, in August 2023, Chandrayaan-3 made history by achieving a successful soft landing near the lunar south pole, making India the first country ever to land in that region and only the fourth nation to achieve a soft landing on the Moon.
Mangalyaan: The Mars Mission
One of ISRO’s most celebrated achievements is the Mars Orbiter Mission, popularly known as Mangalyaan. Launched in 2013 and entering Mars orbit in 2014, it made India the first country in the world to reach Mars on its very first attempt — and did so at a remarkably low cost, drawing worldwide admiration for the efficiency and skill of its engineers. Mangalyaan became a symbol of what focused, frugal innovation can accomplish.
Reaching for the Sun and Human Spaceflight
ISRO continues to push the boundaries of exploration. The Aditya-L1 mission, India’s first dedicated solar observatory, was launched to study the Sun from a special vantage point in space. The agency is also preparing for Gaganyaan, its ambitious human spaceflight programme, which aims to send Indian astronauts into space aboard an indigenously developed spacecraft — a landmark step that would place India among a small group of nations with independent human spaceflight capability.
Serving the Nation
Beyond exploration, ISRO’s work has a profound and practical impact on the lives of ordinary Indians. Its satellites support weather forecasting and cyclone warnings that save lives, telecommunications and television broadcasting, and the NavIC navigation system that provides positioning services for the region. Satellite data aids agriculture, water and forest management, urban planning and disaster response, making space technology a powerful tool for national development.
Cost-Effectiveness and Commercial Growth
ISRO is renowned around the world for delivering complex missions at a fraction of the cost of other space agencies, a result of frugal engineering, indigenous development and dedicated teams. Its commercial arm markets India’s launch and satellite services globally, and in recent years the government has opened up the space sector to private companies and startups, spurring a fast-growing “NewSpace” ecosystem that promises to accelerate India’s space ambitions further.
A Source of National Pride
ISRO’s achievements — delivered efficiently, affordably and largely through indigenous effort — stand as a powerful testament to Indian scientific talent and determination. Each milestone, from Mangalyaan to Chandrayaan-3, has united and inspired the nation and captured global headlines. For millions of young Indians, ISRO is proof that ambition, hard work and ingenuity can take a country all the way to the Moon and beyond, and it continues to inspire dreams of a future among the stars.
The Scientists Behind ISRO
ISRO’s achievements are the work of generations of dedicated scientists and engineers. Its foundations were laid by visionaries such as Dr Vikram Sarabhai, often called the father of the Indian space programme, and Dr Satish Dhawan, after whom the Sriharikota launch centre is named. Dr A. P. J. Abdul Kalam, later the President of India, played a key role in developing launch vehicles. In recent years, teams of scientists — including a growing number of women in leading roles — have carried this legacy forward, embodying a culture of excellence, frugality and national service.
Satellites in Everyday Life
The practical benefits of ISRO’s work touch the lives of ordinary Indians every day, often without their realising it. Communication satellites carry television, telephone and internet signals across the country; remote-sensing satellites monitor crops, water resources, forests and urban growth; meteorological satellites provide the weather forecasts and cyclone warnings that save countless lives; and the NavIC navigation system offers accurate positioning for transport, fishing and emergency services. Space technology has become an invisible but essential part of India’s development.
The Deep Space Network and Ground Infrastructure
Behind every mission lies a vast network of ground infrastructure. ISRO operates launch facilities at Sriharikota on the east coast, satellite-building and control centres, and the Indian Deep Space Network near Bengaluru, which tracks and communicates with distant spacecraft on their journeys to the Moon and Mars. This sophisticated infrastructure, built up over decades, enables India to plan, launch, control and receive data from increasingly ambitious missions.
International Collaboration
While self-reliance has been central to ISRO’s ethos, the agency also collaborates internationally. It has launched satellites for dozens of countries, partnered on scientific missions, and works with other space agencies on shared goals. These collaborations enhance India’s capabilities, strengthen its diplomatic ties, and position it as a valued and trusted partner in the global space community, while its low costs make it an attractive choice for nations seeking affordable access to space.
The Rise of Private Space in India
In recent years, the Indian government has opened up the space sector to private companies, sparking the rapid growth of a “NewSpace” ecosystem of startups building rockets, satellites and space-based services. Supported by reforms and by ISRO’s willingness to share facilities and expertise, these private ventures are set to accelerate innovation, create jobs and expand India’s share of the global space economy, marking an exciting new chapter in the country’s space story.
