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.

The satellite called NISAR — short for NASA-ISRO Synthetic Aperture Radar — will operate from a near-polar-circling orbit 464 miles high. It will join dozens of Earth observation missions already in operation by the U.S. and India.

NASA and India paired up to launch an Earth-mapping satellite on Wednesday capable of tracking even the slightest shifts in land and ice. The $1.3 billion mission will help forecasters and first responders stay one step ahead of floods,
