CAPE CANAVERAL, Fla. (AP) \u2014 NASA<\/a> and India paired up to launch an Earth-mapping satellite on Wednesday capable of tracking even the slightest shifts in land and ice.<\/p>\n

The $1.3 billion mission will help forecasters and first responders stay one step ahead of floods, landslides, volcanic eruptions and other disasters<\/a>, according to scientists.<\/p>\n

Rocketing to orbit from India<\/a>, the satellite will survey virtually all of Earth\u2019s terrain multiple times. Its two radars \u2014 one from the U.S. and the other from India \u2014 will operate day and night, peering through clouds, rain and foliage to collect troves of data in extraordinary detail.<\/p>\n

Microwave signals beamed down to Earth from the dual radars will bounce back up to the satellite\u2019s super-sized antenna reflector perched at the end of a boom like a beach umbrella. Scientists will compare the incoming and outgoing signals as the spacecraft passes over the same locations twice every 12 days, teasing out changes as small as a fraction of an inch (1 centimeter).<\/p>\n

\u201cCongratulations India!\u201d India\u2019s minister of science and technology, Jitendra Singh, said via X once the satellite safely reached orbit. The mission \u201cwill benefit the entire world community.\u201d<\/p>\n

NASA\u2019s deputy associate administrator Casey Swails, part of a small delegation that traveled to India for the launch, said it \u201creally shows the world what our two nations can do. But more so than that, it really is a pathfinder for the relationship building,.\u201d<\/p>\n

It will take a full week to extend the satellite\u2019s 30-foot (9-meter) boom and open the 39-foot-in-diameter (12-meter) drum-shaped reflector made of gold-plated wire mesh. Science operations should begin by the end of October.<\/p>\n

Among the satellite\u2019s most pressing measurements: melting glaciers and polar ice sheets; shifting groundwater supplies; motion and stress of land surfaces prompting landslides and earthquakes; and forest and wetland disruptions boosting carbon dioxide and methane emissions.<\/p>\n

It\u2019s \u201ca first-of-its-kind, jewel radar satellite that will change the way we study our home planet and better predict a natural disaster before it strikes,\u201d NASA\u2019s science mission chief Nicky Fox said ahead of liftoff. She was part of the NASA delegation that attended the launch in person. <\/p>\n

NASA is contributing $1.2 billion to the three-year mission; it supplied the low-frequency radar and reflector. The Indian Space Research Organization\u2019s $91 million share includes the higher-frequency radar and main satellite structure, as well as the launch from a barrier island in the Bay of Bengal. It\u2019s the biggest space collaboration between the two countries.<\/p>\n

The satellite called NISAR \u2014 short for NASA-ISRO Synthetic Aperture Radar \u2014 will operate from a near-polar-circling orbit 464 miles (747 kilometers) high. It will join dozens of Earth observation missions already in operation by the U.S. and India.<\/p>\n
