A SpaceX Falcon 9 rocket with the Surface Water and Ocean Topography (SWOT) spacecraft onboard is seen as it rolls out to the pad, Tuesday, Dec. 13, 2022, at Space Launch Complex 4E at Vandenberg Space Force Base in California. Jointly developed by NASA and Centre National D’Etudes Spatiales, with contributions from the Canadian Space Agency and the United Kingdom Space Agency, SWOT is the first satellite mission that will observe nearly all water on Earth’s surface, measuring the height of water in the planet’s lakes, rivers, reservoirs, and the ocean. SWOT is set to launch at 6:46 a.m. EST on Dec. 15, 2022.
