De flesta av ESA:s rymdfarkoster testas vid Europeiska centrumet f\u00f6r rymdforskning och teknik (ESTEC) i Nederl\u00e4nderna. ESTEC:s testcenter har allt som beh\u00f6vs f\u00f6r att kontrollera en rymdfarkost innan den skickas till uppskjutningsplatsen.<\/p>\n<\/div>\n

Den stora rymdsimulatorn kallas ibland f\u00f6r \u2018rymden i en burk\u2019. Inuti kammaren uts\u00e4tts en satellit f\u00f6r extrema rymdliknande f\u00f6rh\u00e5llanden. Efter att luften har pumpats ut kan satellitens temperatur varieras fr\u00e5n 100 \u00b0C \u2013 vattnets kokpunkt \u2013 ner till fryspunkten -100 \u00b0C. En m\u00e4nniska skulle inte kunna \u00f6verleva vid s\u00e5dana temperaturer!<\/p>\n

S\u00e4rskilda vibrationsprovningsanl\u00e4ggningar anv\u00e4nds f\u00f6r att kontrollera att satelliten t\u00e5l kraftiga vibrationer, s\u00e4rskilt under uppskjutningen. Europas st\u00f6rsta vibrationsprovningsanl\u00e4ggning \u00e4r ESA:s fleraxliga vibrationsprovningsanl\u00e4ggning, som kallas Hydra.<\/p>\n

Den stora europeiska akustikanl\u00e4ggningen s\u00e4kerst\u00e4ller att en satellit klarar det \u00f6ronbed\u00f6vande bullret vid en uppskjutning. Satelliten uts\u00e4tts f\u00f6r ljud fr\u00e5n enorma h\u00f6gtalare.<\/p>\n

Andra tester s\u00e4kerst\u00e4ller att rymdfarkostens elektriska utrustning fungerar som den ska. Noggranna kontroller genomf\u00f6rs f\u00f6r att s\u00e4kerst\u00e4lla att de olika systemen inte p\u00e5verkar varandra. Statisk elektricitet utg\u00f6r ocks\u00e5 ett potentiellt hot.<\/p>\n

Kommunikationsantennerna kontrolleras i en st\u00e5lbur som sk\u00e4rmar av yttre TV- och radiosignaler. V\u00e4ggarna \u00e4r kl\u00e4dda med ett speciellt material s\u00e5 att rummet \u00e4r lika tyst som i den yttre rymden.<\/p>","protected":false},"excerpt":{"rendered":"
