Groundbreaking Satellite to Transform Global Monitoring
In an exciting development for Earth observation, the Indian Space Research Organisation (ISRO) and NASA are poised to launch the innovative NISAR satellite in March 2025 from the Satish Dhawan Space Centre located in Sriharikota. This mission promises to elevate our understanding of the planet by harnessing cutting-edge technology.
NISAR, which stands for NASA-ISRO Synthetic Aperture Radar, is a pioneering satellite that integrates dual-band radar technology using L-band and S-band wavelengths. Its primary function is to detect significant shifts on Earth’s surface, particularly changes incurred by natural disasters like earthquakes, landslides, and volcanic eruptions. Additionally, it will provide critical insights into glacier dynamics, forest degradation, and wetland conditions, pivotal for climate research and disaster readiness.
As highlighted by Paul Rosen, project scientist at NASA’s Jet Propulsion Laboratory, the satellite’s advanced capabilities will allow for weekly monitoring of Earth’s surface, capturing intricate details vital for understanding the planet’s systems.
This initiative exemplifies a remarkable collaboration between NASA and ISRO, which officially began in 2014, joining forces to enhance radar technologies. The data gathered by NISAR will be freely available to researchers worldwide on a cloud-based platform, aiding in the fields of ecosystem monitoring, carbon cycle analysis, and water resource management.
As we look forward to the launch, NISAR is set to revolutionize Earth science and contribute significantly to our efforts in combating climate change.
