L\u2019astronaute Andreas Mogensen est de retour sur Terre ! Apr\u00e8s une br\u00e8ve mission de 10 jours sur la Station spatiale internationale (ISS), Andreas a atterri avec succ\u00e8s sur Terre dimanche dernier aux premi\u00e8res heures de la matin\u00e9e.<\/p>\n<\/div>\n

Le 2 septembre 2015, apr\u00e8s sa mise en orbite, Andreas est officiellement devenu le tout premier astronaute originaire du Danemark. Bien que relativement courte, sa mission a comport\u00e9 de nombreuses exp\u00e9riences scientifiques vraiment tr\u00e8s passionnantes.<\/p>\n

Andreas a notamment test\u00e9 un nouveau type de filtre \u00e0 eau capable de transformer les eaux us\u00e9es en eau potable sans consommer d\u2019\u00e9nergie. Si ces premiers tests s\u2019av\u00e8rent concluants, cette nouvelle technologie pourrait nous \u00eatre utile aussi bien sur Terre que dans l\u2019espace !<\/p>\n

Une autre exp\u00e9rience a amen\u00e9 Andreas \u00e0 porter une \u00ab SkinSuit \u00bb, une combinaison ajust\u00e9e qui a \u00e9t\u00e9 sp\u00e9cialement con\u00e7ue pour r\u00e9duire les probl\u00e8mes de colonne vert\u00e9brale dont souffrent les astronautes en impesanteur. En effet, comme le manque de gravit\u00e9 n\u2019exerce aucune pression sur la colonne vert\u00e9brale des astronautes, celle-ci peut s\u2019allonger de 8 centim\u00e8tres lors d\u2019un s\u00e9jour dans l\u2019espace !<\/p>\n

Croyez-le ou non, mais l\u2019exp\u00e9rience la plus difficile d\u2019Andreas a consist\u00e9 \u00e0 ins\u00e9rer une tige dans un trou. Pour ce faire, l\u2019astronaute de l\u2019ESA a d\u00fb utiliser un robot contr\u00f4l\u00e9 de mani\u00e8re distante \u00e0 plusieurs milliers de kilom\u00e8tres de l\u00e0 ! Ce robot spatial \u00e9tait situ\u00e9 aux Pays-Bas alors qu\u2019Andreas se trouvait 400 kilom\u00e8tres plus haut, \u00e0 bord de l\u2019ISS.<\/p>\n

\u00c0 l\u2019avenir, les techniques exp\u00e9riment\u00e9es par Andreas pourraient \u00eatre utilis\u00e9es par des astronautes en mission dans l\u2019espace afin d\u2019effectuer des exp\u00e9riences avec des robots \u00e0 la surface d\u2019autres plan\u00e8tes.<\/p>\n

Anecdote sympa :<\/b> Andreas a pris depuis la Station spatiale internationale (ISS) les premi\u00e8res photos de jets bleus jaillissant des nuages d'orage. D\u00e9couvrez sa vid\u00e9o d'un orage au-dessus de l'Inde. ici<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
