The NISAR (NASA-ISRO Synthetic Aperture Radar) is a joint NASA / ISRO mission to make global integrated measurements of the causes and consequences of land surface changes. NISAR will study highly spatial and temporally complex processes ranging from ecosystem disturbances, to ice sheet collapse and natural hazards including earthquakes, tsunamis, volcanoes, and landslides.

For this joint project, NASA will provide the mission's L-band synthetic aperture radar (SAR), the high-rate communication subsystem for science data, GPS receivers, a solid state recorder, and a payload data subsystem. ISRO will provide the satellite bus, an S-band synthetic aperture radar, the GSLV Mk.2(1) launch vehicle and associated launch services.

Launch is planned for the year 2019 to 2021 timeframe.
