'Sailing' satellites of the future could provide early warning of dangerous space weather
NOAA is making progress on developing a solar sail to navigate satellites and increase lead time in geomagnetic storm forecasts.
It's important to keep an eye on the solar wind, because when it comes into contact with our planet, it can interact with Earth's magnetic field, creating auroras near the polar regions and, if strong enough, geomagnetic storms. Although storm alerts are issued before this happens, there's still a need for a longer lead time if there's a chance of impacts to different types of technological systems, including power grids, GPS, farming and air traffic. Through NOAA's Space Weather Next program, scientists continue to work on how future satellite missions will assist in providing more advance notice of geomagnetic storms.
