The U.S.-European Surface Water and Ocean Topography (SWOT) mission to study our home planet is currently targeting a Dec. 16, 2022 launch at 3:46 a.m. PST​ from Vandenberg Space Force Base in Central California. The SUV-size satellite will help researchers understand how much water flows into and out of Earth’s freshwater bodies and will provide insight into the ocean’s role in how climate change unfolds.

The measurements from the spacecraft’s science instruments will also help communities monitor and plan for changing water resources as well as the effects of sea level rise. SWOT is a joint mission developed by NASA and the French space agency Centre National d’Études Spatiales (CNES), with contributions from the Canadian Space Agency and the UK Space Agency.
