- Agriculture: Farmers and policymakers will gain insights into soil moisture levels and crop health.
NASA-ISRO NISAR Satellite Set for Early 2025 Launch to Revolutionize Earth Observation
In a significant milestone for global space collaboration, the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is scheduled for launch in early 2025. This joint venture between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO) is poised to transform Earth observation capabilities with its cutting-edge radar technology.
NISAR, the first satellite to feature both NASA’s L-band radar and ISRO’s S-band radar, will be launched from the Satish Dhawan Space Centre in Andhra Pradesh aboard ISRO’s Geosynchronous Satellite Launch Vehicle Mark II. Developed under a 2014 agreement between the U.S. and India, the mission aims to map the Earth every 12 days, delivering continuous and precise data on key environmental and geological changes.
The satellite’s advanced radar payload is supported by a 12-meter drum-shaped, wire-mesh reflector—the largest of its kind in space—along with a gold-colored thermal blanket to maintain operational temperature. The spacecraft bus will handle power, communication, navigation, and orientation for the satellite.
Technologically, NISAR brings together dual-frequency radar systems:
- L-band Radar (NASA): Ideal for detecting ground movements through dense vegetation, making it vital for monitoring volcanoes and seismic zones.
- S-band Radar (ISRO): Enhances surface observation accuracy, operating at 2–4 GHz with an 8–15 cm wavelength.
Applications and Impact
NISAR will provide high-resolution data regardless of weather conditions or daylight, capturing both horizontal and vertical movements of Earth’s surface. Key applications include:
- Disaster Mitigation: Early tracking of earthquakes, landslides, and volcanic activity.
- Environmental Monitoring: Observing forests, wetlands, farmlands, and deforestation trends.
- Infrastructure Assessment: Monitoring urban development and detecting oil spills.
- Climate Research: Measuring changes in sea level, ice mass, and groundwater reserves.
By offering consistent, detailed insights, NISAR will empower policymakers, scientists, and environmentalists with data-driven tools for sustainable planning and disaster resilience. To know more visit your trusted site Hours of news.
