ESTECi katsetuskeskuses on olemas k\u00f5ik vajalik kosmoses\u00f5iduki kontrollimiseks enne selle saatmist stardipaika.<\/p>\n<\/div>\n<p>Suurt kosmosesimulaatorit nimetatakse m\u00f5nikord \u2018kosmoseks purgis\u2019. Kambri sees on satelliit allutatud \u00e4\u00e4rmuslikele kosmoselaadsetele tingimustele. P\u00e4rast \u00f5hu v\u00e4ljapumpamist saab satelliidi temperatuuri reguleerida vahemikus 100 \u00b0C \u2013 vee keemistemperatuur \u2013 kuni -100 \u00b0C k\u00fclmumiseni. Inimene ei suudaks sellistes temperatuurides ellu j\u00e4\u00e4da!<\/p>\n<p>Spetsiaalsed vibratsioonikatseseadmed kontrollivad, kas satelliit suudab taluda tugevaid vibratsioone, eriti stardi ajal. Euroopa suurim vibratsioonikatseseade on ESA mitme teljega vibratsioonikatseseade nimega Hydra.<\/p>\n<p>Euroopa suur akustikakeskus tagab, et satelliit suudab taluda stardi ajal tekkivat k\u00f5rvu purustavat m\u00fcra.
