Geomagnetic storms and auroras show, in sometimes spectacular ways, the effects of charged particles from the Sun on the Earth\u2019s magnetosphere.<\/p>\n<p>The Smile satellite is equipped with four instruments designed to study the effects of the solar wind in various ways. It\u2019s not the first mission designed to study the magnetosphere and its interactions with the solar wind, and each new satellite offers new insights. The Smile mission is the first to focus on the mechanisms that lead to the transfer of energy from the solar wind to the Earth\u2019s atmosphere to observe them fully on a global scale.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A few hours ago, the Smile satellite was launched from the Kourou Spaceport in French Guiana atop a Vega-C rocket.
