An important step in the US-India space cooperative relationship was reached on Wednesday when a US Air Force C-17 airplane arrived in Bengaluru and delivered the NASA-ISRO Synthetic Aperture Radar (NISAR) NISAR to the Indian space agency.
The Indian Space Research Organization (ISRO) and the National Aeronautics and Space Administration (NASA) are working together to create NISAR, a Remotely sensed satellite. NISAR was conceptualized by NASA as well as ISRO in 2014, 8 years prior, as a potent illustration of the capacity of sonar as a scientific tool and as a way to advance our understanding of Earth’s changing terrestrial and glacier surfaces.
It is anticipated to be deployed at Satish Dhawan Space Center into an orbit around the earth in January 2024. At least three years will pass before the spacecraft stops working. It is an observatory in low Earth orbit (LEO). In 12 days, NISAR would map the rest of the world.
Using two distinct radar frequency bands (L-band and S-band), NISAR will be the initial remote sensing technology system to be used in space to methodically map Earth. It will measure the difference in our earth’s crust that is less than a centimeter across.
Advantages of NISAR
To enhance our understanding of Global information systems and environmental degradation, NISAR would provide a great deal of data and information regarding the Earth’s surface variations, environmental events, and ecological disturbances.
Quicker response periods and more accurate risk evaluation will be made possible by the mission’s provision of crucial data to aid in managing natural calamities including tremors, tidal waves, and volcanic activities. By providing data on growing crops, soil humidity, and land-use variations, NISAR data will be utilized to enhance agribusiness management and nutrition security.
Data from the expedition will be used for infrastructural management and monitoring, including tracking of urbanization, forestry, and oil spills. NISAR will aid in seeing and comprehending how climate change has affected the terrestrial surface of the planet, including alterations to sequestering carbon, rising sea levels, and thawing permafrost.
