C'est fait ! Pour la toute premi\u00e8re fois dans l\u2019histoire de l\u2019humanit\u00e9, l\u2019ESA a fait atterrir un module spatial \u00e0 la surface d\u2019une com\u00e8te.<\/p>\n<\/div>\n

Apr\u00e8s un long voyage de 10 ans, Rosetta et Philae ont fini par atteindre au mois d\u2019ao\u00fbt 2014 leur destination finale, la com\u00e8te 67P\/Churyumov-Gerasimenko. La sonde spatiale Rosetta s\u2019est ensuite lentement approch\u00e9e de la com\u00e8te, en se pr\u00e9parant pour son nouveau d\u00e9fi : faire atterrir Philae \u00e0 sa surface.<\/p>\n

Plus Rosetta s\u2019approchait de ce monde inconnu, plus sa beaut\u00e9 se d\u00e9voilait. Nous avons ainsi d\u00e9couvert que la com\u00e8te \u00e9tait parsem\u00e9e de crat\u00e8res, de falaises vertigineuses et d\u2019\u00e9normes rochers entour\u00e9s de jets de gaz et de poussi\u00e8re fusant de la surface.<\/p>\n

Apr\u00e8s avoir \u00e9tudi\u00e9 la surface de la plan\u00e8te pendant plusieurs semaines, les experts ont retenu le meilleur site d\u2019atterrissage pour Philae. Il n\u2019y avait alors plus qu\u2019\u00e0 pr\u00e9parer le d\u00e9ploiement du module spatial pour que Philae puisse atterrir sur la com\u00e8te dans de bonnes conditions.<\/p>\n

L\u2019heure des adieux de Philae et Rosetta \u00e9tait venue, et le point d\u2019orgue de leur mission allait enfin avoir lieu. Tr\u00e8s t\u00f4t hier matin, Philae a commenc\u00e9 sa descente vers la com\u00e8te. Pendant une man\u0153uvre angoissante de sept heures, le monde entier a retenu son souffle alors que Philae fendait l\u2019espace de mani\u00e8re automatis\u00e9e, sans le moindre moyen de rectifier la trajectoire de sa descente.<\/p>\n

Apr\u00e8s quelques minutes d\u2019attente, nous avons pu laisser exploser notre joie en recevant la confirmation de l\u2019atterrissage de Philae : un moment historique dans l\u2019histoire de l\u2019exploration spatiale venait d\u2019avoir lieu !<\/p>\n

Philae a d\u00e9j\u00e0 commenc\u00e9 \u00e0 collecter un maximum d\u2019informations sur ce monde miniature absolument fascinant. Avec Rosetta, qui orbite toujours autour de la com\u00e8te, le petit robot Philae va nous aider \u00e0 percer les myst\u00e8res de l\u2019un des plus anciens objets c\u00e9lestes du syst\u00e8me solaire.<\/p>\n

Anecdote sympa :<\/b> La com\u00e8te Churyumov-Gerasimenko\/67P file actuellement vers le Soleil \u00e0 une vitesse de 60 000 km\/h, soit plus de deux fois la vitesse de la navette spatiale !<\/p><\/p>","protected":false},"excerpt":{"rendered":"
