L’Agence spatiale europ\u00e9enne (ESA) a annonc\u00e9 le report de la mission SMILE, destin\u00e9e \u00e0 observer les vents solaires qui frappent le champ magn\u00e9tique de la Terre, alors que le lancement du satellite \u00e9tait pr\u00e9vu jeudi.
Vega-C, le lanceur l\u00e9ger de l’ESA, devait initialement d\u00e9coller du centre spatial de Kourou en Guyane, avec \u00e0 son bord le satellite SMILE (pour Solar wind Magnetosphere Ionosphere Link Explorer) dans le cadre d’une mission \u00e9labor\u00e9e et r\u00e9alis\u00e9e en collaboration entre l’ESA et l’Acad\u00e9mie chinoise des sciences (ACS).
Mais le lancement a \u00e9t\u00e9 report\u00e9 \u00ab\u00a0\u00e0 une date ult\u00e9rieure\u00a0\u00bb, en raison \u00ab\u00a0d’un probl\u00e8me technique survenu sur la cha\u00eene de production d’un composant du sous-syst\u00e8me apr\u00e8s l’int\u00e9gration du lanceur VV29\u00a0\u00bb, a indiqu\u00e9 l’instance sur son site internet, renvoyant vers un communiqu\u00e9 identique d’Avio, l’entreprise a\u00e9rospatiale italienne ma\u00eetre d’oeuvre du programme spatial Vega.
Les vents solaires naissent des \u00e9jections de masse coronale (CME) qui se produisent \u00e0 la surface du Soleil.
Ces \u00e9jections de plasma provoquent des flux de particules qui se propagent ensuite jusqu’\u00e0 la Terre, \u00e0 une vitesse pouvant atteindre deux millions de kilom\u00e8tres par heure.<\/p>\n","protected":false},"excerpt":{"rendered":"
