**Summary:**
The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, a collaborative Earth observation mission between the United States and India, has been successfully launched. NISAR is unique for using both L-band (NASA) and S-band (ISRO) radars to monitor Earth’s surface. It will provide high-resolution, all-weather data for various applications including tracking land deformation, monitoring ice-sheet dynamics, assessing forest biomass, and improving disaster response. Dr. Karen St. Germain, Director of NASA’s Earth Science Division, highlighted the satellite’s unprecedented ability to detect even minor shifts and changes on Earth’s surface, useful for early warnings of volcanic eruptions, landslides, and tracking deforestation. The mission faced engineering challenges, including impacts from the COVID-19 pandemic and issues with the large deployable reflector antenna. NISAR data, available freely, is expected to benefit agriculture, insurance, finance, transportation, and disaster management. The partnership between NASA and ISRO could set a precedent for future collaborations.

**India-U.S. Space Collaboration Reaches New Heights with Launch of NISAR Satellite**
**CHENNAI, INDIA – August 1, 2025** – A new era in Earth observation dawned on July 31st with the successful launch of NISAR (NASA-ISRO Synthetic Aperture Radar), a joint project between the Indian Space Research Organisation (ISRO) and the National Aeronautics and Space Administration (NASA). This groundbreaking satellite is equipped with both NASA’s L-band and ISRO’s S-band radar, making it the first satellite to utilize dual-frequency radar technology for continuous monitoring of the Earth’s surface.
NISAR promises to provide unprecedented, high-resolution data on various environmental phenomena, including land deformation, ice-sheet dynamics, forest biomass changes, and the impacts of natural disasters like earthquakes and floods. Its all-weather, day-night imaging capabilities will significantly enhance climate resilience, agricultural monitoring, and disaster response efforts globally.
“NISAR will see anything that has structure to it that moves, that changes its position at a scale of less than a centimeter,” explained Dr. Karen St. Germain, Director of NASA’s Earth Science Division. “We’ll be able to see the slight bulging that happens before a volcano erupts or land becoming unstable before a landslide.”
The mission, which cost NASA approximately $1.2 billion, faced significant challenges during its 11-year development, including disruptions due to the COVID-19 pandemic and technical issues with the satellite’s massive deployable antenna. However, the team overcame these hurdles, demonstrating the strength of international collaboration in space exploration.
Beyond its scientific value, NISAR is expected to generate commercial opportunities, enabling new data services, geospatial analytics, and early warning systems across sectors like insurance, infrastructure, and agriculture. Over 200 “Early Adopters” are already anticipating the benefits of NISAR data for their businesses.
The data from NISAR will be freely and openly available through NASA and ISRO distribution channels. This collaborative effort between the United States and India is seen as a model for future partnerships in space exploration and technology sharing. NISAR promises to unlock new insights into our planet and contribute to a more sustainable and resilient future.
