NASA’s first radar images from a new Earth-mapping satellite show the Maine coast and North Dakota farmland in incredible detail. The pictures, released Thursday, are from a spacecraft that rocketed into orbit from India two months ago. The joint U.S.-Indian mission, worth $1.3 billion, will survey virtually all of the world’s land and ice masses multiple times. NASA said these first pictures are a preview of what’s to come once science operations begin in November. The satellite, flying 464 miles (747 kilometers) high in a near polar orbit, is called NISAR, short for NASA-ISRO Synthetic Aperture Radar.
