NASA and the Indian Space Research Organization (ISRO) are teaming up to build and launch a dual-frequency synthetic aperture radar satellite to observe natural processes and hazards such as earthquakes, tsunamis, volcanoes and landslides. The satellite will be called the NASA-ISRO Synthetic Aperture Radar (NISAR) mission.
The satellite’s instruments will be built and developed by NASA, and the satellite will be built and launched by ISRO in India. The target timeline for launch is around 2021.
Data from the NISAR satellite will help scientists understand the planet’s processes. The scientific instruments are an L-band (24-centimeter wavelength) Polarimetric Synthetic Aperture Radar and an S-band (12-centimeter wavelength) Polarimetric Synthetic Aperture Radar.
