Bengaluru: The Indian Space Research Organisation (ISRO) and NASA are gearing up for the launch of the NISAR satellite in March 2025 from the Satish Dhawan Space Centre in Sriharikota. The mission is expected to significantly enhance global Earth observation capabilities.
Key Focus Areas
NISAR, short for NASA-ISRO Synthetic Aperture Radar, is the first satellite to combine dual-band radar technology with L-band and S-band wavelengths. The satellite is designed to track critical changes on Earth’s surface, including land deformation caused by natural disasters such as earthquakes, landslides, and volcanic activity. It will also monitor glacier movement, forest degradation, and wetland dynamics, contributing valuable data to climate science and disaster management efforts.
Paul Rosen, project scientist for NISAR at NASA’s Jet Propulsion Laboratory, emphasized the importance of its high-resolution imaging capabilities. “NISAR will measure Earth’s surface changes weekly, capturing fine details to help us understand the planet’s evolving systems,” he said.
International Collaboration
This mission marks a milestone in international scientific collaboration. NASA and ISRO formalized their partnership in 2014, combining NASA’s expertise in L-band radar with ISRO’s advancements in S-band technology. While the satellite’s core components were designed and developed across continents, the final assembly took place in India.
Open-Source Data for Research
NISAR’s data will be accessible to researchers globally through a cloud platform, enabling applications in ecosystem monitoring, carbon cycle analysis, and water resource management. The satellite’s comprehensive coverage, capturing surface changes weekly, will help scientists and policymakers better understand Earth’s dynamic systems and address global challenges like climate change.
As the launch approaches, NISAR represents a crucial step forward in Earth science, enabling precise and timely monitoring of environmental changes.
