Alle satellit-testomr\u00e5derne p\u00e5 ESTEC er renere end en operationsstue p\u00e5 et hospital, og derfor kaldes de \u2018renrum\u2019.<\/p>\n<\/div>\n

Et renrum er et omr\u00e5de, hvor luften indeholder meget f\u00e5 st\u00f8vpartikler. Da der ikke er st\u00f8v i rummet, er det vigtigt, at der heller ikke er noget st\u00f8v under samling og test. En st\u00f8vpartikel i en afbryder eller et kredsl\u00f8b kan f\u00e5 et rumfart\u00f8j til at svigte. St\u00f8v p\u00e5 spejle eller kameralinser kan g\u00f8re satellitten blind og skal derfor undg\u00e5s.<\/p>\n

Al luften i renrummene filtreres for at fjerne s\u00e5 meget st\u00f8v som muligt. Men det er ikke nok i sig selv.<\/p>\n

Alle, der g\u00e5r ind i renrummet, skal g\u00e5 hen over en kl\u00e6bende gulvm\u00e5tte for at fjerne snavs fra deres sko.<\/p>\n

Derefter tager de en st\u00f8vfri \u2018kanindragt\u2019 p\u00e5. Der tr\u00e6kkes elastiske overtr\u00e6k over deres hoved og sko. Til sidst tager de eventuelt handsker og en ansigtsmaske p\u00e5.<\/p>\n

Luftfugtigheden (luftens vandindhold) i renrum holdes ogs\u00e5 p\u00e5 et ret lavt niveau, og temperaturen holdes t\u00e6t p\u00e5 20 \u00b0C.<\/p>\n

En meget nyttig funktion ved ESA\u2019s testcenter er sammenkoblingen af renrummene. Det betyder, at satellitter nemt kan flyttes til forskellige testomr\u00e5der uden at skulle pakkes ned i containere og dermed risikere at blive forurenet med st\u00f8v.<\/p>","protected":false},"excerpt":{"rendered":"
