Jupiter est la plus grande plan\u00e8te du syst\u00e8me solaire : elle est au moins mille fois plus grosse que la Terre ! Cependant, nous ne savons pas encore tout sur cette g\u00e9ante gazeuse. Tout cela va changer : JUICE, la prochaine mission majeure de l'Agence spatiale europ\u00e9enne, va traverser le syst\u00e8me solaire afin d\u2019explorer Jupiter et plusieurs de ses grandes lunes glac\u00e9es !<\/p>\n<\/div>\n

Le mois dernier, l'ESA a pris une d\u00e9cision tr\u00e8s importante : elle a choisi une entreprise appel\u00e9e Airbus Defence & Space pour concevoir et construire JUICE, et le pr\u00e9parer en vue de son lancement en 2022.<\/p>\n

La sonde spatiale JUICE mettra huit ans pour atteindre Jupiter ! Une fois arriv\u00e9e \u00e0 destination, JUICE prendra trois ans et demi pour \u00e9tudier la plan\u00e8te g\u00e9ante, parcourir son atmosph\u00e8re temp\u00e9tueuse et explorer ses myst\u00e9rieux anneaux sombres.<\/p>\n

Mais la sonde spatiale ne se concentrera pas uniquement sur Jupiter. Elle \u00e9tudiera \u00e9galement trois de ses lunes glac\u00e9es, de la taille d\u2019une plan\u00e8te : Callisto, Europe et Ganym\u00e8de. Les astronomes pensent que chacun de ces mondes lointains pourrait receler de vastes oc\u00e9ans d\u2019eau sous sa surface glac\u00e9e. C\u2019est tr\u00e8s intrigant, car l\u2019eau est essentielle \u00e0 l\u2019existence de la vie !<\/p>\n

JUICE survolera Europa et Callisto avant de terminer sa mission par un tour de Ganym\u00e8de pendant huit mois. Ganym\u00e8de est la lune la plus volumineuse de notre syst\u00e8me solaire. Plus grande que Mercure et Pluton, c\u2019est m\u00eame la seule \u00e0 poss\u00e9der un champ magn\u00e9tique !<\/p>\n

Le travail de JUICE ne nous aidera pas seulement \u00e0 mieux conna\u00eetre la plus grande plan\u00e8te de notre syst\u00e8me solaire : nous pourrons \u00e9galement am\u00e9liorer nos connaissances sur la formation des plan\u00e8tes. Pour finir, JUICE devrait surtout nous apprendre si la vie peut exister sur d\u2019immenses et lointains mondes glac\u00e9s !<\/p>\n
