Alle satellitt-testomr\u00e5dene ved ESTEC er renere enn et operasjonsrom p\u00e5 et sykehus, og kalles derfor \u2018renrom\u2019.<\/p>\n<\/div>\n

Et renrom er et omr\u00e5de hvor luften inneholder sv\u00e6rt f\u00e5 st\u00f8vpartikler. Siden det ikke finnes st\u00f8v i verdensrommet, er det viktig at det ikke finnes st\u00f8v under montering og testing. En st\u00f8vpartikkel i en bryter eller en krets kan f\u00f8re til at et romfart\u00f8y svikter. St\u00f8v p\u00e5 speil eller kameralinser kan gj\u00f8re satellitten blind, og m\u00e5 derfor unng\u00e5s.<\/p>\n

All luften i renrommene filtreres for \u00e5 fjerne s\u00e5 mye st\u00f8v som mulig. Men dette alene er ikke nok.<\/p>\n

Alle som g\u00e5r inn i renrommet, m\u00e5 g\u00e5 over en klebrig gulvmatte for \u00e5 fjerne smuss fra skoene sine.<\/p>\n

Deretter tar de p\u00e5 seg en st\u00f8vfri \u2018kanindrakt\u2019. De trekker elastiske overtrekk over hodet og skoene. Til slutt kan de ta p\u00e5 seg hansker og ansiktsmaske.<\/p>\n

Luftfuktigheten (vanninnholdet i luften) i renrom holdes ogs\u00e5 ganske lav, og temperaturen holdes n\u00e6r 20 \u00baC.<\/p>\n

En sv\u00e6rt nyttig funksjon ved ESAs testsenter er at renrommene er forbundet med hverandre. Dette inneb\u00e6rer at satellitter enkelt kan flyttes til ulike testomr\u00e5der uten at de m\u00e5 pakkes ned i containere og dermed risikere \u00e5 bli forurenset av st\u00f8v.<\/p>","protected":false},"excerpt":{"rendered":"
