Alla satellitprovningsomr\u00e5den vid ESTEC \u00e4r renare \u00e4n en operationssal p\u00e5 ett sjukhus, och kallas d\u00e4rf\u00f6r f\u00f6r \u2018renrum\u2019.<\/p>\n<\/div>\n

Ett renrum \u00e4r ett utrymme d\u00e4r luften inneh\u00e5ller mycket f\u00e5 dammpartiklar. Eftersom det inte finns n\u00e5got damm i rymden \u00e4r det viktigt att det inte f\u00f6rekommer n\u00e5got damm under montering och tester. En dammkorn i en str\u00f6mbrytare eller krets kan leda till att en rymdfarkost slutar fungera. Damm p\u00e5 speglar eller kameralinser kan g\u00f6ra satelliten blind och m\u00e5ste d\u00e4rf\u00f6r undvikas.<\/p>\n

All luft i renrummen filtreras f\u00f6r att avl\u00e4gsna s\u00e5 mycket damm som m\u00f6jligt. Men det r\u00e4cker inte i sig.<\/p>\n

Alla som g\u00e5r in i renrummet m\u00e5ste g\u00e5 \u00f6ver en klibbig golvmatta f\u00f6r att ta bort smuts fr\u00e5n sina skor.<\/p>\n

D\u00e4refter tar de p\u00e5 sig en dammfri \u2018kanindr\u00e4kt\u2019. Elastiska \u00f6verdrag s\u00e4tts p\u00e5 \u00f6ver huvudet och skorna. Till sist kan de ta p\u00e5 sig handskar och en ansiktsmask.<\/p>\n

Luftfuktigheten (luftens vattenhalt) i renrum h\u00e5lls ocks\u00e5 relativt l\u00e5g, och temperaturen h\u00e5lls n\u00e4ra 20 \u00b0C.<\/p>\n

En mycket anv\u00e4ndbar funktion vid ESA:s testcenter \u00e4r att renrummen \u00e4r sammankopplade. Detta inneb\u00e4r att satelliterna enkelt kan flyttas till olika testomr\u00e5den utan att beh\u00f6va packas ned i containrar och d\u00e4rmed riskera att uts\u00e4ttas f\u00f6r dammf\u00f6roreningar.<\/p>","protected":false},"excerpt":{"rendered":"
