Les scientifiques pensent que les lunes de Jupiter pourraient receler d\u2019immenses oc\u00e9ans sous leur surface glac\u00e9e. La mission JUICE de l\u2019ESA a pour objectif de d\u00e9terminer s\u2019il pourrait y avoir de la vie dans ces oc\u00e9ans et s\u2019il existe des mondes habitables autour de g\u00e9antes gazeuses telles que Jupiter. L'ESA s'est attel\u00e9e \u00e0 s\u00e9lectionner les 11 exp\u00e9riences scientifiques qui permettront d'\u00e9tudier la plan\u00e8te g\u00e9ante et ses lunes.<\/p>\n<\/div>\n

La mission d\u2019exploration JUICE (JUpiter ICy moons Explorer) sera lanc\u00e9e en 2022 et arrivera 8 ans plus tard pr\u00e8s de Jupiter, la plus grande plan\u00e8te de notre syst\u00e8me solaire. Elle y passera au moins trois ans afin de proc\u00e9der \u00e0 des observations d\u00e9taill\u00e9es de la plan\u00e8te et de ses trois plus grandes lunes glac\u00e9es: Ganym\u00e8de, Callisto et Europe.<\/p>\n

Les instruments retenus pour cette mission comprennent des cam\u00e9ras, des spectrom\u00e8tres (pour mesurer la lumi\u00e8re), des altim\u00e8tres laser (pour mesurer l\u2019altitude) et un radar permettant d\u2019effectuer des observations \u00e0 travers la glace. JUICE embarquera \u00e9galement un magn\u00e9tom\u00e8tre de mesure des champs magn\u00e9tiques. Le d\u00e9veloppement de ces instruments sera supervis\u00e9 par une \u00e9quipe regroupant des scientifiques de 15 pays europ\u00e9ens, en collaboration avec les \u00c9tats-Unis et le Japon.<\/p>\n

JUICE se placera ensuite en orbite autour de Ganym\u00e8de, d\u2019o\u00f9 elle \u00e9tudiera la surface glac\u00e9e et la structure interne de cette lune, ainsi que l\u2019oc\u00e9an sous sa surface. Ganym\u00e8de est la plus grande lune du syst\u00e8me solaire. C\u2019est la seule capable de g\u00e9n\u00e9rer son propre champ magn\u00e9tique.<\/p>\n

\u201c Jupiter et ses lunes glac\u00e9es constituent en quelque sorte un mini-syst\u00e8me solaire \u00e0 part enti\u00e8re, offrant aux scientifiques europ\u00e9ens et \u00e0 nos partenaires internationaux l\u2019occasion d\u2019en apprendre davantage sur la formation de mondes potentiellement habitables autour d\u2019autres \u00e9toiles \u201d, explique Dmitrij Titov, responsable scientifique de la mission JUICE \u00e0 l\u2019ESA.<\/p>","protected":false},"excerpt":{"rendered":"
