NISAR Satellite's Radar Antenna Reflector Arrives in India

A container holding NISAR’s radar antenna reflector is loaded into NASA’s C-130 cargo plane at March Air Reserve Base in Riverside County, California, on Oct. 15. The aircraft transported the reflector to Bengaluru, India, arriving at ISRO’s satellite integration and test facility on Oct. 22. NASA/JPL-Caltech Read More ›

NASA's Work on NISAR's Antenna Reflector Nears Completion

NASA’s work on the radar antenna reflector for the NISAR satellite is nearing completion in California, with testing under way to verify that this hardware component will deploy properly following launch. Read More ›

Work Continues on NISAR Satellite as Mission Looks Toward Launch

The NISAR (NASA ISRO Synthetic Aperture Radar) satellite – a joint NASA-Indian Space Research Organisation (ISRO) Earth-observing mission – is nearly complete, and a launch readiness date will be determined at the end of April. Read More ›

Trailblazing New Earth Satellite Put to Test in Preparation for Launch

During three weeks in a thermal vacuum chamber in Bengaluru, India, the joint NASA-ISRO satellite demonstrated its hardiness in a harsh, space-like environment. Read More ›

NASA-ISRO Radar Mission to Provide Dynamic View of Forests, Wetlands

NISAR will help researchers explore how changes in Earth’s forest and wetland ecosystems are affecting the global carbon cycle and influencing climate change.

NISAR's data can help people worldwide better manage natural resources and hazards, as well as providing information for scientists to better understand the effects and pace of climate change. It will also add to our understanding of our planet's hard outer layer, called its crust.

Earthquake Hazards and Damage

Earthquakes occur suddenly, often with intense ground shaking that causes loss of life and property. They and their aftershocks can induce landslides, lead to fires, and even bring neighboring faults closer to rupture. NISAR will provide measurements of ground deformation along faults before an earthquake occurs, from the earthquake itself, and in the time following, all key information for understanding where and why earthquakes occur.
Soil Moisture and Water Resources

NISAR will provide maps of surface soil moisture globally every 6 to 12 days at the spatial scale of individual farm fields. This offers unprecedented detail and is vital for monitoring the habitats of plants, animals and humans.

The Magic of SAR

NISAR will be the first radar of its kind in space to systematically map Earth, using two different radar frequencies (L-band and S-band) to measure changes of our planet’s surface, including movements as small as centimeter. Synthetic aperture radar (SAR) refers to a technique for producing fine-resolution images from a resolution-limited radar system.

NASA partnership with the Indian Space Research Organization (ISRO)

NISAR is a joint Earth-observing mission between NASA and the Indian Space Research Organization (ISRO). NASA and ISRO are providing two radars that are optimized each in their own way to allow the mission to observe a wider range of changes than either one alone.
