Vivre dans une station spatiale, c'est un peu comme dans le d\u00e9sert. Il y a tr\u00e8s peu d'eau disponible, chaque goutte est pr\u00e9cieuse.<\/p>\n<\/div>\n

La navette spatiale dispose de piles \u00e0 combustibles qui combinent l'hydrog\u00e8ne et l'oxyg\u00e8ne pour fabriquer de l'\u00e9lectricit\u00e9. De grandes quantit\u00e9s d'eau sont donc fabriqu\u00e9es comme sous-produit. Mais il n'y a pas de pile \u00e0 combustible sur la station spatiale internationale (ISS).<\/p>\n

La quasi-totalit\u00e9 de l'eau utilis\u00e9e \u00e0 bord de l'ISS doit \u00eatre achemin\u00e9e depuis la Terre par la navette spatiale ou par des engins automatiques tels que le Progress russe ou l'ATV de l'ESA. Les astronautes s'en servent pour boire et pr\u00e9parer leurs repas.<\/p>\n

Certaines stations spatiales pr\u00e9c\u00e9dentes \u00e9taient \u00e9quip\u00e9es de douches, mais la navette ou l'ISS n'en disposent pas. Les astronautes utilisent une serviette savonneuse humide pour la toilette. Il n'y a pas non plus de lavage de la vaisselle. Les r\u00e9cipients de nourriture usag\u00e9s sont compact\u00e9s et jet\u00e9s.<\/p>\n

Une partie de l'eau sur l'ISS est extraite de l'air et recycl\u00e9e. Un appareil russe peut produire jusqu'\u00e0 24 kg d'eau par jour de cette fa\u00e7on. Elle est purifi\u00e9e et utilis\u00e9e pour la boisson ou la cuisine.<\/p>\n

Les toilettes utilisent une chasse d'air plut\u00f4t que d'eau pour \u00e9vacuer les excr\u00e9ments humains. L'urine produite par les astronautes est recueillie dans les toilettes puis purifi\u00e9e et recycl\u00e9e.<\/p>","protected":false},"excerpt":{"rendered":"
