De fleste av ESAs romfart\u00f8yer testes ved Det europeiske senteret for romforskning og -teknologi (ESTEC) i Nederland. ESTECs testsenter har alt som trengs for \u00e5 gjennomf\u00f8re tester av et romfart\u00f8y f\u00f8r det sendes til oppskytningsstedet.<\/p>\n<\/div>\n

Den store romsimulatoren kalles noen ganger \u2018rommet i en boks\u2019. Inne i kammeret utsettes en satellitt for ekstreme romlignende forhold. Etter at luften er pumpet ut, kan temperaturen for en satellitt varieres fra 100 \u00b0C \u2013 vannets kokepunkt \u2013 ned til frysepunktet p\u00e5 -100 \u00b0C. Et menneske ville ikke kunne overleve ved slike temperaturer!<\/p>\n

Spesielle ristemaskiner sjekker at satellitten t\u00e5ler sterke vibrasjoner, s\u00e6rlig under oppskytingen. Den st\u00f8rste ristemaskinen i Europa er ESAs fleraksede ristemaskine, kalt Hydra.<\/p>\n

Det store europeiske akustiske anlegget s\u00f8rger for at en satellitt t\u00e5ler den \u00f8red\u00f8vende st\u00f8yen ved en oppskyting. Satellitten blir utsatt for lyd fra enorme h\u00f8yttalere.<\/p>\n

Andre tester sikrer at romfart\u00f8yets elektriske utstyr vil fungere som det skal. Det gjennomf\u00f8res grundige kontroller for \u00e5 sikre at de ulike systemene ikke p\u00e5virker hverandre. Statisk elektrisitet utgj\u00f8r ogs\u00e5 en potensiell trussel.<\/p>\n

Kommunikasjonsantenner testes i et st\u00e5lbur som skjermer for eksterne TV- og radiosignaler. Veggene er kledd med et spesielt materiale, slik at rommet er like stille som i det ytre rom.<\/p>","protected":false},"excerpt":{"rendered":"
