L\u2019Agence spatiale europ\u00e9enne vient d\u2019annoncer que la sonde spatiale Rosetta allait poursuivre son aventure pendant encore neuf mois. Sa mission est officiellement prolong\u00e9e jusqu\u2019\u00e0 la fin du mois de septembre 2016 !<\/p>\n<\/div>\n

L\u2019aventure fascinante de Rosetta a commenc\u00e9 il y a plus de dix ans. La sonde spatiale a \u00e9t\u00e9 lanc\u00e9e en 2004 \u00e0 la poursuite de la com\u00e8te 67P\/Churyumov-Gerasimenko. Pendant une d\u00e9cennie, Rosetta a parcouru le syst\u00e8me solaire pour rejoindre la com\u00e8te, qu\u2019elle a fini par rallier au mois d\u2019ao\u00fbt dernier.<\/p>\n

Mais la mission de Rosetta ne s'est pas arr\u00eat\u00e9e l\u00e0. En r\u00e9alit\u00e9, elle ne faisait que commencer ! La premi\u00e8re mission de Rosetta consistait \u00e0 aider Philae, la petite sonde qu'elle transportait, \u00e0 se poser en toute s\u00e9curit\u00e9 \u00e0 la surface de la com\u00e8te. Sa prochaine mission sera d'accompagner la com\u00e8te dans son voyage autour du Soleil.<\/p>\n

Rosetta va \u00e9tudier les changements de la com\u00e8te alors qu\u2019elle s\u2019approchera de son p\u00e9rih\u00e9lie, le point de son orbite le plus proche du Soleil. L\u2019int\u00e9r\u00eat scientifique des donn\u00e9es qu\u2019elle nous transmettra sera capital !<\/p>\n

Les com\u00e8tes sont d\u2019\u00e9normes boules de neige sales provenant des confins glac\u00e9s de notre syst\u00e8me solaire. \u00c0 mesure qu\u2019elles s\u2019approchent de la chaleur du Soleil, la mati\u00e8re glac\u00e9e proche de leur surface s\u2019\u00e9vapore, comme la vapeur qui s\u2019\u00e9chappe d\u2019une bouilloire. C\u2019est ainsi que les com\u00e8tes se dotent de ces spectaculaires \u201c queues \u201d que l\u2019on aper\u00e7oit lorsqu\u2019elles traversent le ciel nocturne.<\/p>\n

Gr\u00e2ce \u00e0 la prolongation de sa mission, la sonde spatiale Rosetta pourra continuer \u00e0 \u00e9tudier sa com\u00e8te alors qu\u2019elle atteindra son p\u00e9rih\u00e9lie puis s\u2019\u00e9loignera progressivement du Soleil. Cette derni\u00e8re phase de la mission nous fournira de nouvelles informations sur la fa\u00e7on dont les com\u00e8tes \u00e9voluent apr\u00e8s une rencontre rapproch\u00e9e avec le Soleil.<\/p>\n

Mais qu\u2019arrivera-t-il en septembre 2016, au terme du voyage de Rosetta ? Apr\u00e8s avoir accompagn\u00e9 la com\u00e8te 67P pendant de nombreux mois, Rosetta devrait se poser \u00e0 sa surface, puis continuer \u00e0 voyager avec elle \u00e0 travers le syst\u00e8me solaire.<\/p>\n

Anecdote sympa :<\/b> Au cours de ces 9 mois suppl\u00e9mentaires, Rosetta aura \u00e9galement l'occasion de nous offrir une vue rapproch\u00e9e de Philae, la sonde qui s'est pos\u00e9e \u00e0 la surface de la com\u00e8te.<\/p>","protected":false},"excerpt":{"rendered":"
