The synthetic aperture radar (SAR) payloads mounted on integrated radar instrument structure (IRIS) and the spacecraft bus are together called an observatory. 2/n
The observatory will map the entire globe in 12 days & provide spatially & temporally consistent data for understanding changes in Earth’s ecosystems, ice mass, vegetation biomass, sea-level rise, groundwater & natural hazards - earthquakes, tsunamis, volcanoes & landslides. 3/n

Payload integration of #NISAR, a @NASA & @isro joint mission, has been completed. It will be shipped to India later this year for integration with the satellite and eventually the launch vehicle. (It will be launched by Isro) 1/n

A dual SAR mission, #NISAR is a first-of-its-kind endeavour that will be able to operate in two frequencies, both in bands lower than KU-Band or AA-Band. While @isro will develop and provide the S-band radar (12-cm wavelength), @NASA will supply L-band radar (24-cm). 2/n
Thomas Zurbuchen, associate administrator, NASA science mission directorate on future Space exploration, terming it an extremely complex mission, said progress had been made on NISAR after Covid-induced delays. 3/n
