See NASA’s GUARDIAN Catch a Tsunami

A new data visualization illustrates how an experimental NASA technology can provide extra lead time to communities in the path of a tsunami. Called GUARDIAN (GNSS Upper Atmospheric Real-time Disaster Information and Alert Network), the software detects slight distortions in satellite navigation signals to spot hazards on the move.. The animation breaks down a real-life […]

US-French Satellite Takes Stock of World’s River Water

Rivers rise and fall throughout the year, but by how much? Perhaps less than previously thought, according to new data from the SWOT mission. Hidden riverbed contours are also emerging. In a first, a space mission led by NASA and France has tracked Earth’s rivers swelling and shrinking from month to month over the course […]
