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 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...

Meet some of the scientists and engineers contributing to a new Earth science mission, led by NASA and the French space agency Centre National d’Études Spatiales (CNES). The Surface Water and Ocean...

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...

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...

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...

Using the vehicle of multi-media entertainment and a real-life scenario, Dr. Faisal Hossain, a member of the SWOT Science Definition Team, and a Fulbright Scholar has experimented with an alternati...

The SWOT satellite will survey rivers wider than 100 m (328 ft). Three products will be delivered to users. They will only be generated for rivers recorded in an existing database and will cover re...

The deployment of SWOT's solar panels is featured in this animation.

SWOT will collect data across a 120 km wide swath, with a gap in the center for an altimetry track.

The SWOT satellite is set to survey the height, area and changes in volume over time in lakes with a surface area of 6 hectares (15 acres) or more (i.e., an outline of 250 m by 250 m or 820 ft by 8...

An animation of the streams, tributaries and rivers that make up the Mississippi watershed.

This short educational documentary was created by SWOT PI Dr. Faisal Hossain to showcase to the potential value of current and emerging water satellites for society.

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...

This visualization shows the progression of improved data resolution from satellite altimeters in the past, present, and future.

Earth is our home. The SWOT mission will give us a better understanding of our world’s oceans and terrestrial surface waters while showing us why these resources are so important.

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.

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