July 30 became a historic day for India and the whole world, when NASA and ISRO joint project NISAR (NASA-Isro Syntic Aperture Radar) satellite was successfully launched. The launch took place at 5:40 pm from Satish Dhawan Space Center in Sriharikota, Andhra Pradesh, which is being seen as a big jump in India’s space science.

Nisar satellite made in partnership between ISRO and NASA
NISAR i.e. Nasa-Isro Syntic Aperture Radar is a special satellite, which is prepared by ISRO of India and NASA of America. Its purpose is to inspect the surface of the earth very closely so that the complex processes on our earth can be understood. This satellite will monitor the changes in the forests, the breakdown of snow sheets, the rise of sea level, lack of ground water and natural disasters.

Even 1 centimeter change in the surface of the earth will be able to catch
Nisar’s radar is the first device of its kind in space in terms of technology, which will work very accurately. It will scan the surface of the entire Earth in a systematic way and will also measure such changes that will be equal to only 1 centimeter. This means that this satellite can already indicate us of natural disasters and can be warned in time.

Mission NISAR characteristics
The NISAR mission jointly developed by Space Agencies ISRO and NASA of India and the United States is the first satellite mission of its kind. This satellite uses advanced sweep SAR technology, which is capable of taking pictures of broad area with high resolution. NISAR was launched by GSLV rocket from Sriharikota at Sun-Synchronous Polar Orbit, which is the first mission of GSLV in this class.

After the launch, the first 90 days will be held in commissioning or in-orbit checkout (IOC). This satellite will provide 3D photos of the land and ice of the Earth, which will help scientists a lot of earthquakes, landslides, sea ice and glaciers monitoring, crop management and disaster warning system. This satellite will also play an important role in policy and planning to deal with governments to deal with natural and human-related dangers. The NISAR, NASA and ISRO launched by now is the most advanced radar system, which will provide large amounts of data on a daily basis.

Configuration and operation of spacecraft
The NISAR spacecraft is based on the I-3K structure of ISRO and includes two major payloads-L-band and S-band synthetic aperture radar (SAR). The S-band radar system, data handling, high-speed downlinks, spacecraft and launch system have been developed by ISRO, while L-band radar, GPS receiver, solid-set recorder, 12 meter reflector and 9 meter boom have been provided by NASA.

ISRO will take over the command and operation of the spacecraft of this mission, while the NASA Orbital Operations and Radar Operation Scheme will be provided. Ground stations of both ISRO and NASA will be used for data obtaining and processing data. L and S-Band SAR data obtained from the same platform will give scientists accurate information in understanding the subtle changes happening on the Earth’s surface.

India’s Nasa-Isro Nisar Satellite is going to be launched today. This mission is considered to be a “gamechanger” in Space Science, Earth Observation and Climate Study. America’s NASA and India’s ISRO have partnered for this level high-tech radar satellite for the first time. The specialty of NISAR is its dual-band Synthetic Aperture Radar Technology, which will make the entire Earth’s survey possible every 12 days. Through this satellite, disasters like earthquake, tsunami, landslides will help in many other functions along with alert and mapping. Let’s know what this satellite will do, why it is so important and how can you see its launch live.

What is NISAR Satellite?

NISAR (NASA-Isro Syntic Aperture Radar) is the first sanitary aperture radar satellite that has been designed with two different radar techniques with two different radar techniques. Its main objective is to continuously monitor the Earth’s surface, crops, glaciers, forest areas, beaches and natural disasters.

What will NISAR work?

• The specialty of NISAR is its dual-band Synthetic Aperture Radar Technology, which will make the entire Earth’s survey possible every 12 days. Through this satellite:
• Earthquakes, tsunamis, landslides alert and mapping of disasters: It will be able to detect the movement of the land, crust change and displacement with great accuracy.
• Glacier melting and rising sea level: NISAR will monitor Arctic/Himalayan glacier, which will make global warming monitoring and water resources prevention easier.
• Crops and environment/forest health: High-government imaging of satellite will detect crop conditions, erosion, annual forest cover and illegal cuttings.
• Wetland and coastal ecosystem protection: Mapping of rivers, wetlands, mangroves, disturb areas.

These data will be available to thousands of researchers, meteorologists and disaster management teams not only in India, but all over the world. With this, better and accurate decisions will be taken in the field of agricultural policy, afforestation, water management, smart cities and disaster preparation in the coming years.

How powerful is Nisar?

This satellite will be launched from India’s Srihari Space Port with an antenna of 8 meters and about 2.8 tons. Its imaging space is so high level that it is still very rare in Space Science to find the capabilities as much as it can record as small changes in the surface of the earth.

When and where will the launch be from?

NISAR will be launched this evening from Indian time (ISRO’s Satish Dhawan Space Center, Andhra Pradesh). This satellite by PSLV-XL rocket will be installed in low-end orbit.

How to see NISAR launch? (How to watch live)

Live Telecast will be made available for free on ISRO’s official YouTube channel and website (isro.gov.in).
There will also be live streaming of launch on NASA’s YouTube channel and nasa.gov/live.

The most state -of -the -art satellite ‘Nisar’ (NISAR), prepared for the Earth monitoring, will be launched on Wednesday (July 30, 2025). It has been jointly developed by the Indian Space Research Organization (ISRO) and the US Space Agency NASA. This state-of-the-art satellite will be launched from Satish Dhawan Space Center in Sriharikota, India at 5:40 pm via GSLV-F16 rocket.

The purpose of ‘Nasar’ means Nasa-Isro Syntic Aperture Radar Mission is to accurate and continuously monitor the changes on the Earth’s surface. This satellite will operate from a height of 740 km from the Earth in space and will be able to take high-resolution photos day and night, in the morning, evening, in every season, even though clouds and rains.

Nisar satellite is equipped with joint technology of India and America

The specialty of this satellite jointly developed by India and the United States is that it will scan the land and icy surface of the entire earth every 12 days and provide accurate information up to the centimeter level. It has L-Band developed by the US and S-Band radars prepared by India, which are counted among the most advanced techniques in the world.

Satellite will be possible for real monitoring natural disasters

With the help of Nisar, real-time monitoring of natural disasters such as earthquakes, floods, tsunamis, landslides, volcanic eruptions and melting of glacier will be possible. In addition, this technique will also play an important role in the study of climate change, agriculture, coastal erosion and soil moisture.

In this mission, prepared at a cost of about $ 1.3 billion, ISRO and NASA have worked for more than a decade. This mission is being considered a major step not only for India and America, but also globally in the field of disaster management and environmental protection.
