ISRO

India has a special group for space.

It is called ISRO. This group builds big rockets. They use rockets to send things up high.

They sent ships to the Moon. They even sent one to Mars. These ships help us see far away. They can also help us find our way.

ISRO works hard to learn about space.

ISRO is India's space agency.

Its main office is in Bengaluru. It studies space and makes new tools. ISRO also sends satellites into orbit. These satellites help with maps and weather. They also help people find their way.

India's space work began many years ago. A scientist named Vikram Sarabhai helped start it.

In 1975, India launched its first satellite. It was named Aryabhata. In 1980, India used its own rocket to reach orbit. This was a big step for the country.

ISRO has done many great things lately. It sent a ship to the Moon in 2008. This ship looked for water on the Moon. In 2013, ISRO sent a ship to Mars. It was the first Asian ship to reach Mars. In 2023, ISRO landed a ship near the Moon's south pole.

This was a world first. ISRO is also working on a mission to send people into space. This is called Gaganyaan.

The Indian Space Research Organisation, or ISRO, is India's national space agency.

Its main office is in Bengaluru, Karnataka. ISRO is the main part of the Department of Space. The Prime Minister of India oversees this department. ISRO's job is to explore space and create new technology. They also manage many satellites for imaging and communication.

These satellites help people with many important tasks. They can help during disasters or help doctors with telemedicine.

ISRO works by launching many different kinds of rockets. These rockets carry satellites into orbit or send probes to other worlds.

Some rockets are small, while others are much larger. For example, the LVM3 is a heavy-lift launcher used for big satellites. The agency also uses cryogenic engines. These are special engines that use very cold fuel to provide power.

This technology allows India to launch heavy objects into space. ISRO even performs space docking. This is when two satellites meet and join together in space.

India's journey into space started with early scientific studies. In the 1920s, S. K. Mitra studied the upper atmosphere. Later, scientists like C. V. Raman and Meghnad Saha helped too.

In 1962, the government set up a group called INCOSPAR. This was done because scientist Vikram Sarabhai recommended it. The group was later renamed ISRO in 1969.

This change helped make space research a formal part of India.

ISRO has reached many amazing milestones with real numbers. In 1975, India launched its first satellite, Aryabhata. In 1980, the RS-1 satellite made India the seventh country to reach orbit.

ISRO has sent three missions to the Moon. One famous mission was Chandrayaan-1 in 2008. In 2013, the Mars Orbiter Mission reached Mars. On August 23, 2023, the Chandrayaan-3 mission landed near the lunar south pole. This was a world first for any space program.

Many things we use today link back to space technology. The navigation systems like IRNSS help people find their way.

These systems are similar to the GPS used on phones. ISRO also works on the Gaganyaan mission. This project aims to send humans into space.

This will be a huge step for Indian science. Space research helps improve engineering and many other fields too.

The Indian Space Research Organisation, known as ISRO, is India's national space agency.

Headquartered in Bengaluru, Karnataka, it serves as the primary research and development arm for the Department of Space (DoS). The Prime Minister of India oversees this department. The Chairman of ISRO also acts as the chief executive of the DoS. ISRO is responsible for space-based operations and space exploration. It also manages international space cooperation and develops related technologies. The agency maintains a massive constellation of satellites for imaging, communications, and remote sensing.

ISRO functions through a complex system of launch vehicles and satellite constellations. To reach space, the agency uses various rockets to carry payloads. These include small-lift and medium-lift launch vehicles for different mission needs. One major system is the Polar Satellite Launch Vehicle (PSLV). The PSLV became a major boost for India in the 1990s. After its first flight in 1994, it achieved a streak of over 50 successful flights.

For heavier satellites, ISRO uses the LVM3, a heavy-lift launcher. The agency also utilizes cryogenic engines. These engines use extremely cold fuel to provide high power. This technology allows ISRO to deploy satellites into complex orbits. ISRO is one of only six agencies globally with full launch capabilities, including cryogenic engines.

Space exploration involves distinct types of missions and technologies. ISRO manages navigation systems like the IRNSS, which is now called NaVIC. This system helps with positioning and navigation. The agency also conducts deep space missions to other planets. For example, the Mars Orbiter Mission reached Martian orbit in 2013. This made India the first country to succeed at this on its first attempt. Another advanced capability is space docking. In early 2025, the SpaDeX mission successfully demonstrated spacecraft rendezvous and docking. This makes India the fourth country to achieve successful space docking. This process allows two satellites to meet and join together as one entity.

The history of Indian space science began with early individual experiments. In the 1920s, S. K. Mitra studied the ionosphere using ground-based radio in Kolkata. Later, scientists C. V. Raman and Meghnad Saha contributed to important scientific principles. In 1962, Prime Minister Jawaharlal Nehru established INCOSPAR. This was done following a recommendation from scientist Vikram Sarabhai.

INCOSPAR was later renamed ISRO in 1969. In 1972, the government created a space commission and the DoS. This move institutionalized space research in India. This structure brought ISRO under the formal oversight of the Department of Space.

India's journey reached major milestones through specific technological achievements. In 1975, ISRO built its first satellite, Aryabhata, which the Soviet Union launched. A major turning point occurred in 1980. ISRO launched the RS-1 satellite using its own SLV-3 launch vehicle. This made India the seventh country to undertake orbital launches.

Later, the development of the GSLV helped India reach geostationary orbits. Although the US blocked access to certain cryogenic technology, India developed its own indigenous cryogenic technology over two decades. This allowed for much more powerful and reliable space launches.

Recent years have seen incredible successes in lunar and solar exploration. In 2008, the Chandrayaan-1 mission was launched to study the Moon. This probe was the first to verify the presence of water on the Moon. In August 2023, the Chandrayaan-3 mission achieved a historic soft landing.

This mission made India the first nation to land near the lunar south pole. It also made India the fourth nation to land on the Moon. Following this, ISRO launched Aditya-L1 in September 2023. This was India's first solar probe, designed to study the Sun.

ISRO's work has significant connections to both civilian and military needs. The agency's technology supports disaster management and telemedicine. It also provides essential data for reconnaissance and navigation. These technologies help improve socio-economic development across the country. Furthermore, ISRO's spin-off technologies aid innovations in many engineering domains. The agency is even preparing for human spaceflight through the Gaganyaan programme. This mission aims to send humans into space, representing a massive step for Indian science.
