Introduction

The Indian Space Research Organisation (ISRO) is the main space research organisation in India. It was started in 1969, with the help and support of the Prime Minister of India. ISRO’s first leader, Dr. Vikram Sarabhai, helped set strong goals for the new agency. He wanted to use space technology to bring good changes and development to the country. ISRO has worked hard in space exploration and space research since then. Over time, the Indian space research organisation has made several key achievements. A big one for ISRO was the Mars Orbiter Mission, also called Mangalyaan. This showed people everywhere that India can do great work in space and use new space technology for the future.

ISRO is India’s main space agency. Its work is not just about space missions. ISRO helps build communication satellites and weather forecasting tools. It also uses remote sensing, which helps in many different fields. ISRO is always working to find new and better ways to do things in science. In the future, ISRO is set to reach even bigger goals.

ISRO works on big projects and helps spark new ideas for the next wave of scientists and engineers. Because of this, ISRO has become one of the top names in space exploration. ISRO also makes the Indian people feel proud and gives them the drive to keep working towards sending missions to Mars and other places in space.

Comprehensive List of ISRO Missions (1950–2025) and Beyond

When you look at the full journey of the Indian Space Research Organisation, you see many big moments in space research and space exploration. Each step, from satellite launches to trips to the moon, has helped to make space technology better for all. This group has done important projects. A few of these are the Mars Orbiter Mission and several other spacecraft missions used for remote sensing and for checking what is in the air around Earth. Looking to the future, there will be new projects that hope to improve international space cooperation. This will also open up more chances for research in space. These plans will help ISRO keep its role as a top team in space technology and space research. The Indian space research organisation is well-known for its spacecraft missions, like the Mars Orbiter, and is respected across the globe for its work in space exploration.

1. Early Satellite Launches: Aryabhata, Bhaskara, and Rohini Series

ISRO, also known as the Indian Space Research Organisation, started its space exploration journey when it launched Aryabhata in 1975. This was India’s first man-made satellite. Even with the early technology at that time, Aryabhata was very important. The satellite helped bring new ideas to how a spacecraft can be made. Aryabhata gave important information that helped India grow in the space research organisation field and guided future missions for the Indian isro.

After Aryabhata did well, ISRO brought out the Bhaskara satellites to help with remote sensing and earth observation. Bhaskara-I went into space in 1979. It played a big part in making weather forecasting better and helped in farming, too. This showed how much progress India and ISRO made in space technology.

In 1980, ISRO started the Rohini series. The team sent satellites into space using India’s first made-in-the-country satellite launch vehicle. These Rohini missions showed that India got better at using sounding rockets and handling what goes up during space operations. The early work built a strong base for ISRO in space science. It also helped India get better at making and using satellite launch vehicles and spacecraft.

2. Landmark Missions: Chandrayaan, Mars Orbiter, and Astrosat

The Chandrayaan missions have had a big impact on lunar exploration and India’s space program. In 2008, India launched Chandrayaan-1. This was the country’s first successful mission to get to the Moon’s orbit. It also led to the discovery of water molecules on the Moon’s surface. This important finding changed what we know about the Moon and what it is made of. It also helped India become an important part of global space research.

After Chandrayaan-1, Chandrayaan-3 made a big mark by making a safe landing on the Moon in 2023. This moment was an important win for the Indian Space Research Organisation (ISRO). It showed the world that ISRO is a strong name in lunar orbit and space exploration. Many people around the world praised the Indian space research organisation for this. It made others trust ISRO even more, because of how well the team planned each step and how the technology worked during the mission.

Another great achievement for ISRO is the Mars Orbiter Mission, which many people call Mangalyaan. It was launched in 2013. With this project, India became the first Asian nation to reach the orbit of Mars. Mangalyaan sent back useful information about Mars’ atmosphere, and it did this with a budget far lower than most similar missions. The data collected from the Mars Orbiter Mission has helped us learn a lot about Mars and how other planets work.

In 2015, Astrosat was sent into space. It became India’s first special observatory in space. Astrosat has helped India and others study many things about space. People use it to look at black holes, cosmic rays, how stars change, and the solar corona. These big steps show that India is growing in the field of space exploration. The country can work well with other nations. This teamwork helps people everywhere learn more about the universe. ISRO does good work here. It shows that India can push limits, try new ideas, and take part in big space projects across the globe.

3. Major Ongoing and Recent Missions: Cartosat, RISAT, GSAT, and NavIC

The Cartosat series shows how ISRO keeps moving forward with remote sensing technology. These satellites are sent up from time to time. They take clear pictures from space. These pictures help make good maps and help the military do their job well. The pictures are also very useful in city planning and helping people better handle disasters.

The Cartosat series is not just useful for India. It gives data that helps other countries too. This data is important for things like watching the environment and helping with farming. By using the latest technology in these satellites, ISRO shows that it is an important part of the global space world.

The use of artificial intelligence and machine learning in image work from Cartosat satellites helps make data analysis more correct and faster. This way of working makes mapping easier. It also lets people find new ways to use the data in resource management and building new things.

As ISRO keeps reaching for more with every new Cartosat satellite, you can see big changes happen in many areas. These steps that ISRO takes help bring about new ideas and better ways of doing things. This is true not just in India, but around the world, too.

Along with the Cartosat satellites, the Indian Space Research Organisation (ISRO) has also made great progress with its GSAT communication satellites. These satellites use new technology. The GSAT satellites help with safe TV signals, phone calls, and internet services for many different areas. A major project, the GSAT-29 satellite, has helped bring the internet and phone services to distant villages and places that do not have these services. This helps close the digital gap and gives more people in these parts a chance to be connected.

The new features in these satellites have made the country’s networks better. They also help with disaster management and give people in far-away areas more information and resources. The Indian Space Research Organisation continues to work on new ways to use satellite communication for the people. Thanks to all its hard work, ISRO is helping connect people and support development across India.

Another big achievement by ISRO is NavIC. This is an indigenous satellite navigation system made by India, and it works like GPS. NavIC helps with land surveying, making it better and faster. It also improves vehicle tracking systems and helps ships find their way more accurately at sea. These recent steps show that ISRO is working hard to boost India’s technology and support the development of the whole nation.
