Scientists call this mysterious outflow the “polar wind,” and for almost 60 years, spacecraft have been flying through it as scientists have theorized about its cause. The leading theory was that a planet-wide electric field was drawing those particles up into space. But this so-called ambipolar electric field, if it exists, is so weak that all attempts to measure it have failed – until now.In 2022, scientists traveled to Svalbard, a small archipelago in Norway, to launch a rocket in an attempt to measure Earth’s ambipolar electric field for the first time. This was NASA’s Endurance rocketship mission, and this is its story.To learn more, visit: https://science.nasa.gov/science-research/heliophysics/nasa-discovers-long-sought-global-electric-field-on-earth/ || ", "hits": 380 }, { "id": 14025, "url": "https://svs.gsfc.nasa.gov/14025/", "result_type": "Produced Video", "release_date": "2021-11-29T11:00:00-05:00", "title": "Strong Winds Power Electric Fields in the Upper Atmosphere", "description": "Using observations from NASA’s 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 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.More information: https://www.nasa.gov/feature/goddard/2021/strong-winds-power-electric-fields-in-upper-atmosphere-icon/ || ", "hits": 120 }, { "id": 13625, "url": "https://svs.gsfc.nasa.gov/13625/", "result_type": "Produced Video", "release_date": "2020-05-25T11:00:00-04:00", "title": "First Map of Mars Electric Currents", "description": "MAVEN data have enabled the first map of the electric current systems (blue and red arrows) that shape the induced magnetic field surrounding Mars.Credit: NASA/Goddard/MAVEN/CU Boulder/SVSUniversal Production Music: “A Lucid Dream” and “Shimmer Oscillations” by James Joshua OttoWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || MarsElectricCurrentsPreview6_print.jpg (1024x576) [305.8 KB] || MarsElectricCurrentsPreview6.jpg (1920x1080) [853.6 KB] || MarsElectricCurrentsPreview6_searchweb.png (320x180) [50.6 KB] || MarsElectricCurrentsPreview6_thm.png (80x40) [5.3 KB] || 13625_Mars_Electric_Currents_Twitter.mp4 (1280x720) [63.8 MB] || 13625_Mars_Electric_Currents_Facebook.mp4 (1920x1080) [359.1 MB] || 13625_Mars_Electric_Currents_YouTube.webm (3840x2160) [91.7 MB] || 13625_Mars_Electric_Currents_Captions.en_US.srt [7.2 KB] || 13625_Mars_Electric_Currents_Captions.en_US.vtt [6.8 KB] || 13625_Mars_Electric_Currents_YouTube.mp4 (3840x2160) [2.8 GB] || 13625_Mars_Electric_Currents_MASTER.mov (3840x2160) [14.2 GB] || 13625_Mars_Electric_Currents_Facebook.mp4.hwshow [134 bytes] || ", "hits": 106 }, { "id": 20252, "url": "https://svs.gsfc.nasa.gov/20252/", "result_type": "Animation", "release_date": "2017-10-18T12:00:00-04:00", "title": "Phobos Electric Charging", "description": "The interaction of the solar wind with the Martian moon Phobos creates a complex electrical environment that could impact future exploration.
