SWOT: Earth Science Satellite Will Help Communities Plan for a Better Future

A new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES), will help communities plan for a better future by surveying the planet’s salt and freshwater bodies. The Surface Water and Ocean Topography (SWOT) mission will measure the height of water in lakes, rivers, reservoirs, and the oceans. As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough
