SWOT:Earth Science Satellite Will Help Communities Plan for a Better Future
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. SWOT data will be used to improve flood forecasts and monitor drought conditions, providing essential information to water management agencies, civil engineers, universities, the U.S. Department of Defense, disaster preparedness agencies, and others who need to track water in their local areas. In this video, examples of how SWOT data will be used in these communities are shared by a National Weather Service representative in Oregon, an Alaska Department of Transportation engineer, researchers from the University of Oregon and University of North Carolina, a NASA Jet Propulsion Laboratory scientist working with the Department of Defense, and a JPL scientist working with the Louisiana Coastal Protection and Restoration Agency.
SWOT is expected to launch from Vandenberg Space Force Base in California in December 2022. The mission is a collaboration between NASA and CNES, with contributions from the Canadian Space Agency and UK Space Agency. JPL, which is managed for NASA by Caltech in Pasadena, California, leads the U.S. component of the project.

133 Days on the Sun
The video you are looking for is called "133 Days on the Sun" and it was published by NASA on Jan 6, 2023. It shows the solar activity from Aug. 12 to Dec. 22, 2022, as captured by NASA’s Solar Dynamics Observatory (SDO). SDO is a spacecraft that orbits Earth and observes the Sun in high resolution and different wavelengths of light. The video shows the Sun's outermost layer, the corona, which is very hot and dynamic. You can see bright regions, loops, flares, and eclipses in the video. The video is available on NASA's website¹ and YouTube³. You can also read more about it on Space.com². I hope this helps you learn more about our amazing star. 😊
