Kaikki ESTECin satelliittitestausalueet ovat puhtaampia kuin sairaalan leikkaussali, joten niit\u00e4 kutsutaan \u2018puhdastiloiksi\u2019.<\/p>\n<\/div>\n

Puhdastila on tila, jonka ilmassa on hyvin v\u00e4h\u00e4n p\u00f6lyhiukkasia. Koska avaruudessa ei ole p\u00f6ly\u00e4, on t\u00e4rke\u00e4\u00e4, ettei sit\u00e4 ole my\u00f6sk\u00e4\u00e4n kokoonpanon ja testien aikana. Yksikin p\u00f6lyhiukkanen kytkimess\u00e4 tai piiriss\u00e4 voi aiheuttaa avaruusaluksen vian. Peileihin tai kameran linsseihin kertynyt p\u00f6ly voi tehd\u00e4 satelliitista sokean, joten sit\u00e4 on v\u00e4ltett\u00e4v\u00e4.<\/p>\n

Kaikki puhdastilojen ilma suodatetaan, jotta siit\u00e4 poistetaan mahdollisimman paljon p\u00f6ly\u00e4. Pelkk\u00e4 t\u00e4m\u00e4 ei kuitenkaan riit\u00e4.<\/p>\n

Jokaisen puhdastilaan saapuvan on kuljettava tarttuvan lattiamaton yli, jotta kengist\u00e4 irtoaa lika.<\/p>\n

Sitten he pukeutuvat p\u00f6lytt\u00f6m\u00e4\u00e4n \u2018pupupukuun\u2019. P\u00e4\u00e4n ja kenkien p\u00e4\u00e4lle asetetaan joustavat suojukset. Lopuksi he voivat pukea k\u00e4sineet ja kasvomaskin.<\/p>\n

My\u00f6s puhdastilojen ilmankosteus (ilman vesipitoisuus) pidet\u00e4\u00e4n melko alhaisena, ja l\u00e4mp\u00f6tila pidet\u00e4\u00e4n noin 20 \u00baC:ssa.<\/p>\n

Yksi ESA:n testauskeskuksen eritt\u00e4in hy\u00f6dyllisist\u00e4 ominaisuuksista on puhdastilojen keskin\u00e4inen yhteys. T\u00e4m\u00e4 tarkoittaa, ett\u00e4 satelliitteja voidaan helposti siirt\u00e4\u00e4 eri testausalueille ilman, ett\u00e4 niit\u00e4 tarvitsee pakata kontteihin ja vaarantaa p\u00f6lysaastumista.<\/p>","protected":false},"excerpt":{"rendered":"
