Il s’agit de clich\u00e9s pris par la cam\u00e9ra Osiris depuis l’orbiteur Rosetta \u00e0 une distance de la com\u00e8te d’environ 15 kilom\u00e8tres avec une r\u00e9solution de 28 centim\u00e8tres par pixel. Les heures sont en GMT (Greenwich<\/a> Mean Time<\/em>), il faut ajouter 1 heure pour avoir l’heure de Paris. Pendant sa descente l’atterrisseur se d\u00e9place d’ouest en est \u00e0 une vitesse d’environ 0,5m\/sec. Deux images permettent de voir la zone du premier rebond (touchdown point<\/em>) avant et apr\u00e8s.<\/p>\n

La position d\u00e9finitive de Philae n’est toujours pas connue mais les ing\u00e9nieurs de l’ESA sont confiants : l’analyse en cours d’autres images prises par Rosetta et Philae pendant ses rebonds devraient permettre de localiser l’atterrisseur.<\/p>\n","protected":false},"excerpt":{"rendered":"
