A basic view of the orbits for ICON (Ionospheric Connections Explorer) and GOLD (Global-scale Observations of the Limb and Disk). These missions will conduct measurements of ionospheric composition, ionization, and winds to better understand the connection between space weather and its terrestrial impacts.In this visualization, we present GOLD (in geostationary orbit around Earth) and ICON (in low Earth orbit). The colors over Earth represent model data from the IRI (International Reference Ionosphere) model of the density of the singly-ionized oxygen atom at an altitude of 350 kilometers. Red represents high density. The ion density is enhanced above and below the geomagnetic equator (not perfectly aligned with the geographic equator) on the dayside due to the ionizing effects of solar ultraviolet radiation combined with the effects of high-altitude winds and the geomagnetic field. ||

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/ ||

Visualization of ICON in Earth orbit, camera ahead of the spacecraft looking back on spacecraft and limb of Earth. Magenta curves are lines of Earth's geomagnetic field. Field-of-view (FOV) of MIGHTI imagers (green frustums) and the longitudinal wind vectors (green arrows) it measures are shown. MIGHTI imagers FOV eventually fades out. Vertical plasma speed (red arrows) is measured at the spacecraft. Magnetic field lines turn yellow as measurements of winds by MIGHT provide a connection to influence the plasma velocity measured at the spacecraft, redirecting the plasma flow from upward to downward. || ICONDataView.ICONSyncView+x_.clockSlate_CRTT.HD1080i.000750_print.jpg (1024x576) [135.0 KB] || ICONDataView.ICONSyncView+x_.clockSlate_CRTT.HD1080i.000750_searchweb.png (320x180) [79.4 KB] || ICONDataView.ICONSyncView+x_.clockSlate_CRTT.HD1080i.000750_thm.png (80x40) [5.7 KB] || frames/1920x1080_16x9_30p/ICONSyncView+x/ (1920x1080) [256.0 KB] || ICONDataView.ICONSyncView+x.HD1080i_p30.mp4 (1920x1080) [36.4 MB] || ICONDataView.ICONSyncView+x.HD1080i_p30.webm (1920x1080) [5.1 MB] || frames/3840x2160_16x9_30p/ICONSyncView+x/ (3840x2160) [256.0 KB] || ICONDataView.ICONSyncView+x.2160p30.mp4 (3840x2160) [114.3 MB] ||

The Ionospheric Connection Explorer, or ICON, is a low-Earth orbiting satellite that will give us new information about how Earth’s atmosphere interacts with near-Earth space — a give-and-take that plays a major role in the safety of our satellites and reliability of communications signals. Specifically, ICON investigates the connections between the neutral atmosphere — which extends from here near the surface to far above us, at the edge of space — and the electrically charged part of the atmosphere, called the ionosphere. The particles of the ionosphere carry electrical charge that can disrupt communications signals, cause satellites in low-Earth orbit to become electrically charged, and, in extreme cases, cause power outages on the ground. ||

The Coupled Ion Dynamics Investigation (CINDI) is a joint NASA/Air Force funded Ionospheric plasma sensor. This animation shows how the ionosphere changes between Daytime and nighttime. ||

NASA-funded researchers have unveiled a new '4D' live model of Earth's ionosphere at the Space Weather Workshop, Boulder, CO. Without leaving home, anyone can fly through the dynamic layer of ionized gases that encircles Earth at edge of space itself. All that's required is a connection to the Internet. Airline flight controllers can use this tool to plan long-distance flights over the poles, saving money and time for flyers. ||
