The Indian Space Research Organisation (Isro) sent its s-band synthetic aperture radar to Nasa’s Jet Propulsion Laboratory for integration with their l-band radar last week. Coupled together, the Nasa-Isro Synthetic Aperture Radar (NISAR) will become the first satellite to enable earth observation in two frequencies.
After integration, the payload will be sent back to India for launch from the country’s only spaceport at Sriharikota sometime in April or May next year.
According to Nasa, the satellite will provide an “unprecedented view of the Earth” at less than one centimetre across.
It will help scientists understand the surface as well as the interior of the planet we live on. It will provide better understanding of the effects and pace of climate change by measuring ice sheet collapses, officials said.
The satellite will also allow governments to better manage natural disasters—the satellite will provide highly spatial data on tsunamis, earthquakes, landslides,and volcanoes. And,it will also help in better management of natural resources, including detection of disturbances in ecosystems.
