Toutes les zones d'essai des satellites \u00e0 l'ESTEC sont plus propres qu'un bloc op\u00e9ratoire d'h\u00f4pital ; c'est pourquoi on les appelle des \u2018 salles blanches \u2019.<\/p>\n<\/div>\n

Une salle blanche est une zone o\u00f9 l'air ne contient que tr\u00e8s peu de particules de poussi\u00e8re. Il n'y a aucune poussi\u00e8re dans l\u2019espace, il est donc essentiel qu'il n'y en ait aucune lors de l\u2019assemblage et des essais. Une infime particule de poussi\u00e8re dans un interrupteur ou un circuit pourrait causer une panne sur un engin spatial. La poussi\u00e8re sur les miroirs ou les objectifs des cam\u00e9ras peut rendre aveugle le satellite, elle doit donc \u00eatre \u00e9vit\u00e9e \u00e0 tout prix.<\/p>\n

La totalit\u00e9 de l\u2019air des salles blanches est filtr\u00e9e pour \u00e9liminer autant de poussi\u00e8re que possible. Mais ce n\u2019est pas suffisant.<\/p>\n

Chaque personne entrant dans la salle blanche doit traverser un tapis collant permettant d\u2019\u00e9liminer toute trace de salet\u00e9 de ses chaussures.<\/p>\n

Ils enfilent ensuite une \u2018 combinaison anti-poussi\u00e8re \u2019. Des housses \u00e9lastiques sont plac\u00e9es sur leur t\u00eate et leurs chaussures. Enfin, ils peuvent enfiler des gants et un masque.<\/p>\n

L\u2019hygrom\u00e9trie (quantit\u00e9 d\u2019eau contenue dans l\u2019air) dans les salles blanches est aussi maintenue relativement bas et la temp\u00e9rature voisine de 20\u00b0C.<\/p>\n

L'une des caract\u00e9ristiques tr\u00e8s utiles du centre d'essais de l'ESA r\u00e9side dans l'interconnexion des salles blanches. Cela permet de d\u00e9placer facilement les satellites vers diff\u00e9rentes zones d'essais sans avoir \u00e0 les emballer dans des conteneurs, ce qui \u00e9vite tout risque de contamination par la poussi\u00e8re.<\/p>","protected":false},"excerpt":{"rendered":"
