NASA announced Wednesday it, in a partnership with the Indian Space Research Organization, has launched a radar system to map Earth as never before.

The U.S. and India just launched NISAR, a powerful radar satellite that will be able to monitor changes in Earth's surface that are as small as a centimeter.

A formidable new radar satellite jointly developed by the United States and India launched Wednesday, designed to track subtle changes in Earth's land and ice surfaces and help predict both natural and human-caused hazards.
