Smile mission goes aloft to map Earth’s magnetosphere in X-rays
A European-Chinese satellite named Smile launched on a Vega-C rocket to image Earth’s magnetosphere in X‑rays for the first time, offering an outside view of how the solar wind interacts with the magnetic shield. The mission, a rare ESA–Chinese Academy of Sciences partnership, aims to test global magnetosphere models and improve space-weather forecasts, with first images due about three months after launch and a planned three‑year mission.
