SpaceX launches NASA’s water topography satellite into orbit
Dec. 16 (UPI) -- The Surface Water and Ocean Topography satellite launched Friday morning from the Vandenberg Space Force Base in California. The SpaceX 9 rocket lifted off at 6:47 a.m., launching the mission that will provide NASA's first global survey of water on Earth's surface, measuring the elevation of water in major lakes, rivers and wetlands while observing ocean features in higher definition than ever before. The data will help researchers better understand the availability of Earth's freshwater resources, track regional sea level changes and monitor coastal processes. "Once in orbit, SWOT will measure the height of water in freshwater bodies and the ocean on more than 90% of Earth's surface," NASA officials said in a statement. "This information will provide insights into how th...
