De fleste af ESA\u2019s rumfart\u00f8jer testes p\u00e5 Det Europ\u00e6iske Center for Rumforskning og -teknologi (ESTEC) i Nederlandene. ESTEC\u2019s testcenter r\u00e5der over alt det n\u00f8dvendige udstyr til at gennemf\u00f8re en test af et rumfart\u00f8j, inden det sendes til opsendelsesstedet.<\/p>\n<\/div>\n

Den store rumsimulator kaldes undertiden for \u2018rummet i en d\u00e5se\u2019. Inde i kammeret uds\u00e6ttes en satellit for ekstreme, rumlignende forhold. N\u00e5r luften er pumpet ud, kan satellitens temperatur varieres fra 100 \u00b0C \u2013 vandets kogepunkt \u2013 ned til frysepunktet p\u00e5 -100 \u00b0C. Et menneske ville ikke kunne overleve ved s\u00e5danne temperaturer!<\/p>\n

Specielle rysteapparater sikrer, at satellitten kan modst\u00e5 kraftige vibrationer, is\u00e6r under opsendelsen. Det st\u00f8rste rysteapparat i Europa er ESA\u2019s fleraksede rysteapparat, der kaldes Hydra.<\/p>\n

Det store europ\u00e6iske akustiske testanl\u00e6g sikrer, at en satellit kan modst\u00e5 den \u00f8red\u00f8vende st\u00f8j ved en opsendelse. Satellitten uds\u00e6ttes for lyd fra k\u00e6mpe h\u00f8jttalere.<\/p>\n

Andre test sikrer, at rumfart\u00f8jets elektriske udstyr fungerer korrekt. Der foretages omhyggelige kontroller for at sikre, at de forskellige systemer ikke p\u00e5virker hinanden. Statisk elektricitet udg\u00f8r ogs\u00e5 en mulig trussel.<\/p>\n

Kommunikationsantennerne kontrolleres i et st\u00e5lbur, der afsk\u00e6rmer for eksterne tv- og radiosignaler. V\u00e6ggene er bekl\u00e6dt med et specielt materiale, s\u00e5 rummet er lige s\u00e5 stille som det ydre rum.<\/p>","protected":false},"excerpt":{"rendered":"
