First SWOT data with engineer, Curtis Chen

The Surface Water and Ocean Topography mission (SWOT) will help scientists monitor Earth’s ocean, as well as the amount of freshwater in its lakes and rivers when it launches in late 2022. After e...

Nine months after the mission’s successful launch, the SWOT Science Team met in Toulouse, France, bringing together 300 people from 17 countries on all continents to discuss the results obtained wi...

Tahani Amer oversees several Earth science missions for NASA, including the international Surface Water and Ocean Topography (SWOT) satellite, a mission led by NASA and the French space agency Cent...

Earth’s 370 quintillion gallons of water can be found all over the planet in lakes, rivers, glaciers, oceans, and groundwater. However, only a tiny fraction of this water is usable by humans. Under...

Coastal areas are subjected to erosion from waves breaking on shore and storms. Satellite altimetry from the Jason series can provide information on sea level rise, which can be used in planning be...

The Surface Water and Ocean Topography (SWOT) satellite deployed its solar arrays while in Earth orbit.

This video gallery produced by CNES highlights some of the first images from the SWOT mission, from sea ice extent to coastal sea height to river and lake measurements around the globe.

This visualization shows ocean surface currents around the world during the period from June 2005 through December 2007.

Measuring Water from Space: Tamlin Pavelsky, SWOT’s Hydrology Science Lead and Professor at UNC’s College of Arts and Sciences, explains how SWOT data is being validated from North Carolina to New ...

NASA and CNES (French Space Agency) are collaborating to make the first global survey of Earth's surface fresh water and study fine-scale ocean currents with a new mission called SWOT, or Surface W...

Highlights from the Dec. 15, 2022, launch of the Surface Water and Ocean Topography (SWOT) satellite, a mission led by NASA and the French space agency Centre National d’Études Spatiales (CNES). SW...

This animation features the fully deployed SWOT satellite over Earth.

The ocean is responsible for Earth's mild climate and makes life on Earth possible for all creatures. As global ocean temperatures increase, the ocean water expands causing sea level rise which can...

To become operational in orbit, SWOT will need to deploy components that were stored for the launch and orbit insertion process. First, the solar panels will deploy to power the spacecraft. This an...

Where There's Water...There's SWOT provides an overview of the Surface Water and Ocean Topography (SWOT) mission, which will make the first global survey of Earth's surface water.

The SWOT satellite's research instruments and components packaged and ready for transport to Thales Alenia Space near Cannes, France. Traveling from March Air Force Base in Riverside County, Califo...

The water cycle is how atmosphere, land and ocean processes interact with each other.

Source: To become operational in orbit, SWOT will need to deploy components that were stored for the launch and orbit insertion process. After the solar panels have been extended, the booms and ant...

Watch with NASA as we launch an international mission to understand the Earth's water like never before.  

SWOT will include a Ka-band Radar Interferometer (KaRIn) that will send and receive radar pulses to antennas mounted on booms attached to the spacecraft.
