La sonde Solar Orbiter de l’Agence spatiale europ\u00e9enne (ESA) a d\u00e9coll\u00e9 \u00e0 5h03 le lundi 10 f\u00e9vrier en direction du Soleil. Son objectif est d’\u00e9tudier le comportement du Soleil.<\/p>\n\n\n\n

Un p\u00e9riple de plusieurs ann\u00e9es l’attend qui lui permettront de s’approcher \u00e0 seulement 42 millions de kilom\u00e8tres du Soleil ! (La temp\u00e9rature de la surface du Soleil est de 5000\u00b0C) Elle \u00e9tudiera \u00e9galement ses p\u00f4les depuis une position jamais atteinte par une sonde.\u00a0 <\/p>\n\n\n\n

Pour cela, la sonde embarque 10 instruments de mesure\u00a0in situ<\/em>\u00a0et de t\u00e9l\u00e9d\u00e9tection qui collecteront photos et\u00a0spectres<\/a>, mesureront le\u00a0plasma<\/a>\u00a0du\u00a0vent solaire<\/a>, les champs, les ondes et les particules \u00e9nerg\u00e9tiques \u00e0 proximit\u00e9 du Soleil. <\/p>\n\n\n\n

Les vents solaires sont des temp\u00eates de particules projet\u00e9es dans l’espace.<\/p>\n\n\n\n

Quand les particules solaires heurtent la Terre, elles peuvent endommager les syst\u00e8mes \u00e9lectriques, les satellites et les radars. Solar Orbiter doit aider les scientifiques \u00e0 mieux pr\u00e9voir ces ph\u00e9nom\u00e8nes pour mieux s’en d\u00e9fendre.<\/p>\n\n\n\n
