About NISAR (NASA-ISRO Synthetic Aperture Radar) Mission:

NISAR is a joint Earth-Observation mission between ISRO and NASA. It aims to make global measurements of land surface changes using advanced radar imaging.
Objective: To improve understanding of the impact of climate change on Earth’s changing Ecosystems, land and coastal processes, land deformations, and Cryosphere.
Features: It is a dual-band (L-band and S-band) Radar imaging mission with the capability of full polarimetric and interferometric modes of operation, to observe minor changes in land, vegetation, and cryosphere.
Contributions: NASA is developing L-band SAR and associated systems. While ISRO is developing S-band SAR, spacecraft bus, the launch vehicle, and associated launch services.
