NASA satellite will use radar to map Earth's crust in extreme detail

Scientists will soon have a spaceborne tool to study environmental changes at a very high resolution, and you won't have long to wait to learn more about it. NASA's Jet Propulsion Laboratory is holding a question and answer session today (February 3rd) at 5PM Eastern to discuss NISAR (NASA-ISRO SAR), an Earth-mapping satellite built in tandem with the Indian Space Research Organization. It's not launching from India until early 2024 and is planned to operate for three years, but it includes breakthrough tech that could help understand Earth and cope with natural disasters.
