Strong Winds Power Electric Fields in the Upper Atmosphere, NASA’s ICON Finds

Using observations from NASA’s Ionospheric Connection Explorer (ICON) mission, scientists presented the first direct measurements of Earth’s long-theorized dynamo on the edge of space: a wind-driven electrical generator that spans the globe 60-plus miles above our heads. The dynamo churns in the ionosphere, the electrically charged boundary between Earth and space. It’s powered by tidal winds in the upper atmosphere that are faster than most hurricanes and rise up from the lower atmosphere, creating an electrical environment that can affect satellites and technology on Earth. The new work, published today in Nature Geoscience, improves our understanding of the ionosphere, which helps scientists better predict space weather and protect our technology from its effects.

This data visualization shows the ICON spacecraft in orbit around Earth. The green arrows show the strong, high-altitude winds — known as atmospheric tides — detected by ICON’s MIGHTI wind imager. These winds are not uniform and can be altered by changes in the lower-altitude atmosphere. This, in turn, changes the particle motion high in the ionosphere. Changes in plasma at 370 miles above Earth’s surface were also detected by ICON as shown in red. Magnetic field lines are shown in magenta and turn yellow as measurements of winds detected by MIGHTI (green arrows) influence the direction of plasma (red arrows).
