NASA and ISRO joint collaboration to build NISAR….


Guwahati/ 21st December’2017 (Prag News Desk): NASA, ISRO and Jet Propulsion Laboratory (JPL) are working on the development of Dual Frequency (L&S band) Synthetic Aperture Radar Imaging Satellite named as NASA-ISRO Synthetic Aperture Radar (NISAR). The L-band SAR was developed by JPL/NASA, while S-band SAR is being developed by ISRO. The L & S band microwave data gained from this satellite will be useful for various application, estimating agricultural biomass over full duration of crop cycle; natural resources mapping & monitoring; assessing soil moisture; monitoring of floods and oil slicks; coastal erosion, coastline variations and changes of  of winds in coastal waters; surface deformation studies, ice sheet collapses & dynamic assessment of mangroves etc.

NISAR mission’s data is not meant for building climate resilience. But, the data acquired from this mission will be resourceful in developing many applications. Few of them are,  identifying crevasses in the glaciers hidden by fresh snow, identifying the snowpack parameters as an input in Avalanche forecasts, studying Glacial Lake Outburst Floods (GLOF) hazards, and identifying inundated area due to cyclones or floods. These applications will be really helpful to save the lives of human.

The NISAR satellite, is scheduled to launch four years from now from India. Using the Geo-Synchronous Satellite Launch Vehicle (GSLV) also promise to strengthen Indo-US bonds in the coming time.
