A new satellite by NASA’s Jet Propulsion Laboratory will soon provide more precise — and vital — data on how much water is available on Earth’s surface, allowing better forecasts for extreme weather conditions such as droughts and floods, and helping water resources managers and farmers to get a better picture of their water budget.

The international Surface Water and Ocean Topography or SWOT mission was launched in December 2022 from Vandenberg Space Force Base atop a Falcon 9 rocket.
