Le vendredi 14 avril 2023, \u00e0 14h14, la fus\u00e9e Ariane 5 transportant la sonde JUICE (Jupiter Icy Moons Explorer) a \u00e9t\u00e9 lanc\u00e9e avec succ\u00e8s depuis le port spatial de Kourou, en Guyane fran\u00e7aise. Avec ce lancement, l’Universit\u00e9 de Berne<\/a> entame un voyage de huit ans vers le syst\u00e8me jovien, o\u00f9 la mission explorera trois lunes glac\u00e9es en utilisant la technologie d\u00e9velopp\u00e9e par l’Universit\u00e9 \u00e0 la recherche de signes de vie.<\/p>\n

L’Agence spatiale europ\u00e9enne (ESA<\/a>) a confirm\u00e9 la s\u00e9paration r\u00e9ussie de la sonde spatiale de la fus\u00e9e et le d\u00e9ploiement des panneaux solaires qui alimenteront la sonde. La sonde commence maintenant son voyage pour explorer la plus grande plan\u00e8te de notre syst\u00e8me solaire, Jupiter, et trois de ses plus de 80 lunes : Ganym\u00e8de, Callisto et Europe.<\/p>\n

La mission JUICE<\/a> transporte dix instruments scientifiques, avec l’Universit\u00e9 de Berne contribuant au spectrom\u00e8tre de masse Neutral and Ion Mass Spectrometer (NIM), faisant partie du Particle Environment Package (PEP), et participant \u00e0 deux autres instruments : le Submillimeter Wave Instrument (SWI) et l’altim\u00e8tre laser GALA.<\/p>\n

Sous la direction de Peter Wurz, le NIM a \u00e9t\u00e9 d\u00e9velopp\u00e9 et construit \u00e0 l’Institut de physique<\/a> de l’Universit\u00e9 de Berne. Le spectrom\u00e8tre de masse \u00e9tudiera la composition chimique et isotopique et la r\u00e9partition des particules dans les atmosph\u00e8res des lunes glac\u00e9es de Jupiter, ainsi que les param\u00e8tres physiques de ces atmosph\u00e8res.<\/p>\n

Dirig\u00e9 par Axel Murk, l’Institut de physique appliqu\u00e9e<\/a> a d\u00e9velopp\u00e9 l’optique et l’unit\u00e9 de calibration pour le SWI. Le SWI mesurera la stratosph\u00e8re de Jupiter et les atmosph\u00e8res et surfaces des lunes glac\u00e9es de Jupiter. Au lieu de la lumi\u00e8re visible, l’instrument mesurera le rayonnement thermique de la stratosph\u00e8re de Jupiter dans des longueurs d’onde submillim\u00e9triques, d\u00e9terminant la r\u00e9partition de la temp\u00e9rature, la composition et les vents dans l’atmosph\u00e8re, ainsi qu’\u00e9tudiant les atmosph\u00e8res et les propri\u00e9t\u00e9s de surface des lunes.<\/p>\n

L’altim\u00e8tre laser GALA, qui comprend un module de t\u00e9l\u00e9m\u00e8tre d\u00e9velopp\u00e9 sous la direction de Nicolas Thomas, examinera la topographie de Ganym\u00e8de.<\/p>\n

Le gouvernement f\u00e9d\u00e9ral suisse soutient la mission JUICE au travers du programme PRODEX<\/a> (PROgramme de D\u00e9veloppement d’EXp\u00e9riences scientifiques) de l’Agence spatiale europ\u00e9enne. Ce programme permet aux \u00e9quipes de projet issues de la recherche et de l’industrie de d\u00e9velopper et de construire des contributions pour des missions scientifiques, favorisant le transfert de connaissances et de technologies entre la science et l’industrie. En fin de compte, cette collaboration offre un avantage concurrentiel pour la Suisse et permet aux technologies, aux processus et aux produits de se diffuser dans d’autres march\u00e9s, apportant une valeur ajout\u00e9e \u00e0 l’\u00e9conomie.<\/p>\n","protected":false},"excerpt":{"rendered":"
