The NISAR Satellite: Everything You Need to Know! (May 27)

An important step in the cooperation between the two nations in the sphere of space research was made on March 8, 2023, when a C-17 aircraft from the US Air Force landed in Bengaluru and delivered the NASA-ISRO Synthetic Aperture Radar (NISAR) to the Indian space agency. The Indian Space Research Organization (ISRO) and the National Aeronautics and Space Administration (NASA) are collaborating to develop the NISAR Earth observation satellite.

All You Need to Know About NISAR Collab!

NISAR was planned by NASA and ISRO 8 years ago in 2014 as a potent demonstration of radar’s potential as a scientific tool and to aid in our more in-depth understanding of Earth’s dynamic land and ice surfaces. From the Satish Dhawan Space Center, it will be launched into a close-to-polar orbit in January 2024. For a minimum of 3 years, the satellite will be in operation. An LEO observatory is what it is. In just 12 days, NISAR will scan the whole world.

NISAR, the pioneering radar system deployed in space, will perform a systematic Earth mapping by precisely measuring minute surface variations with two distinct radar frequencies. With the extensive data and insights provided by NISAR, we will gain a comprehensive understanding of Earth’s system, climate change, ecosystem disruptions, and natural calamities. This valuable information will contribute to enhancing awareness about the processes influencing our planet.

The NISAR Satellite - Everything you Need to know!

Enhancing agriculture management and food security will be possible thanks to the data’s information on crop growth, soil moisture, and changes in land use. The mission will offer information for managing and monitoring infrastructure, including surveillance of urbanization, deforestation, and oil spills. The satellite will assist in observing and comprehending how climate change is affecting the terrestrial surface of the planet, including glacier melt, sea level rise, and adjustments to carbon storage.


  1. What is the full form of NISAR?

    The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite

  2. What is the NISAR satellite?

    The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite is a joint collaboration between NASA (National Aeronautics and Space Administration) and ISRO (Indian Space Research Organisation). It is designed to observe and monitor Earth’s surface using advanced radar imaging technology.

  3. How long will the NISAR mission operate?

    The NISAR mission is expected to operate for several years, collecting continuous data to support ongoing Earth science research and applications.

  4. How will the NISAR satellite contribute to addressing global challenges such as climate change and natural disasters?

    The NISAR satellite will contribute to addressing global challenges such as climate change and natural disasters by providing valuable data for understanding Earth’s processes and dynamics, improving predictive models, and enhancing preparedness and response efforts for mitigating risks and impacts.

  5. What are the potential applications of NISAR satellite data?

    Potential applications of NISAR satellite data include monitoring natural disasters such as earthquakes, floods, and landslides, studying climate change impacts, assessing crop health and vegetation dynamics, mapping changes in polar ice caps, and monitoring urbanization and infrastructure development.

  6. Where can researchers access NISAR data for scientific studies?

    Once operational, NISAR data will be freely available to researchers and the public through data archives maintained by NASA and ISRO, as well as through specialized research portals and data analysis tools.

  7. Where will the NISAR satellite be launched from?

    The NISAR satellite is planned to be launched from the Satish Dhawan Space Centre in Sriharikota, India, using a GSLV (Geosynchronous Satellite Launch Vehicle) Mk II rocket.

  8. How does the NISAR satellite work?

    NISAR uses Synthetic Aperture Radar (SAR) technology that can penetrate clouds and operate in darkness, unlike optical cameras. It sends microwave radar signals towards the Earth and captures the signals that bounce back, allowing it to create detailed images and three-dimensional reconstructions of Earth’s surface.

  9. When is the NISAR satellite expected to launch?

    The NISAR satellite is scheduled to launch in late 2023.
