  2. NASA-ISRO SAR (NISAR) is a Low Earth Orbit (LEO) observatory being jointly developed by NASA and ISRO. NISAR will map the entire globe in 12 days and provide spatially and temporally consistent data for understanding changes in Earth’s ecosystems, ice mass, vegetation biomass, sea level rise, ground water and natural hazards including ...

  3. The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite in 2025. The satellite will be the first radar imaging satellite to use dual frequencies.

  4. 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. Learn More.

  5. The NASA-ISRO SAR (NISAR) Mission will measure Earth’s changing ecosystems, dynamic surfaces, and ice masses providing information about biomass, natural hazards, sea level rise, and groundwater, and will support a host of other applications.

  6. The NISAR observatory carries a 12m wide deployable mesh reflector mounted onto a deployable 9m boom developed by JPL which shall be used by both-JPL-NASA developed L-Band SAR payload system and ISRO developed S-Band SAR payload.

  7. NISAR is the first satellite mission to collect radar data in two microwave bandwidth regions, called the L-band and the S-band, to measure changes of our planet’s surface, including movements as small as centimeter.

  8. Aug 21, 2024 · Overview. NISAR Satellite (Image credit: NASA) Summary. Mission Capabilities. NISAR has two Synthetic Aperture Radars (SARs) onboard, an L-band (L-SAR) and an S-band (S-SAR), and will be the first satellite to use two different radar frequencies.
