Africa-Press – Burkina Faso. <\/strong><\/span>Le tout premier satellite construit en bois devrait de\u0301coller a\u0300 bord d’une fuse\u0301e SpaceX en septembre, ont annonce\u0301 les chercheurs japonais qui ont re\u0301ussi cette premie\u0300re mondiale.<\/p>\n

Eviter la formation de particules me\u0301talliques<\/b><\/p>\n

Ce satellite expe\u0301rimental cubique de\u0301veloppe\u0301 par des scientifiques de l’Universite\u0301 de Kyoto et de la socie\u0301te\u0301 forestie\u0300re Sumitomo Forestry mesure 10 cm de co\u0302te\u0301. Ses cre\u0301ateurs s’attendent a\u0300 ce que le bois bru\u0302le totalement lorsque l’appareil rentrera dans l’atmosphe\u0300re, ce qui permettra d’e\u0301viter la formation de particules me\u0301talliques lors du retour du satellite sur Terre. \u00ab\u00a0Les satellites qui ne sont pas fabrique\u0301s en me\u0301tal devraient e\u0302tre privile\u0301gie\u0301s\u00a0\u00bb, a de\u0301clare\u0301 Takao Doi, astronaute et professeur spe\u0301cial a\u0300 l’Universite\u0301 de Kyoto, lors d’une confe\u0301rence de presse le 28 mai.<\/p>\n

Sa re\u0301sistance teste\u0301e<\/b><\/p>\n

Les de\u0301veloppeurs pre\u0301voient de remettre le satellite LignoSat, fabrique\u0301 a\u0300 partir de bois de magnolia, a\u0300 l’agence spatiale japonaise JAXA la semaine prochaine. Il sera envoye\u0301 dans l’espace a\u0300 bord d’une fuse\u0301e SpaceX depuis le Centre spatial Kennedy en septembre, a\u0300 destination de la station spatiale internationale (ISS), ont-ils pre\u0301cise\u0301.<\/p>\n

Le satellite sera ensuite libe\u0301re\u0301 depuis le module expe\u0301rimental japonais de l’ISS pour tester sa re\u0301sistance et sa durabilite\u0301 dans l’espace. \u00ab\u00a0Les donne\u0301es seront envoye\u0301es depuis le satellite aux chercheurs qui pourront ve\u0301rifier les signes de tension et s’il peut re\u0301sister a\u0300 d’e\u0301normes changements de tempe\u0301rature\u00a0\u00bb, a de\u0301clare\u0301 a\u0300 l’AFP une porte-parole de Sumitomo Forestry.<\/p>\n

Le 28 mai, une fuse\u0301e transportant un autre satellite \u2013 une collaboration entre l’Agence spatiale europe\u0301enne (ESA) et la JAXA \u2013 a de\u0301colle\u0301 de Californie pour une mission visant a\u0300 e\u0301tudier le ro\u0302le que les nuages pourraient jouer dans la lutte contre le changement climatique. Le satellite EarthCARE sera en orbite a\u0300 pre\u0300s de 400 km au-dessus de la Terre pendant trois ans.<\/p>\n
