Ve\u010dina vesoljskih plovil agencije ESA se testira v Evropskem centru za vesoljske raziskave in tehnologijo (ESTEC) na Nizozemskem. Testni center ESTEC razpolaga z vsem, kar je potrebno za preizkus vesoljskega plovila, preden se to odpelje na izstrelitveno mesto.<\/p>\n<\/div>\n

Simulator velikega vesolja se v\u010dasih imenuje tudi \u2018vesolje v plo\u010devinki\u2019. V komori je satelit izpostavljen ekstremnim pogojem, podobnim tistim v vesolju. Po iz\u010drpanju zraka je mogo\u010de temperaturo satelita spreminjati od 100 \u00b0C \u2013 to\u010dke vreli\u0161\u010da vode \u2013 do -100 \u00b0C, kar je temperatura zamrzovanja. \u010clovek pri tak\u0161nih temperaturah ne bi pre\u017eivel!<\/p>\n

Posebni vibracijski preskusni aparati preverjajo, ali satelit lahko prenese mo\u010dne vibracije, zlasti med izstrelitvijo. Najve\u010dji vibracijski preskusni aparat v Evropi je ve\u010dosni vibracijski preskusni aparat agencije ESA, imenovan \u00bbHydra\u00ab.<\/p>\n

V velikem evropskem akusti\u010dnem centru preverjajo, ali satelit lahko prenese oglu\u0161ujo\u010di hrup ob izstrelitvi. Satelit je izpostavljen zvoku, ki prihaja iz ogromnih zvo\u010dnikov.<\/p>\n

Drugi preskusi zagotavljajo, da bo elektri\u010dna oprema vesoljskega plovila delovala pravilno. Izvajajo se natan\u010dni pregledi, da se prepre\u010di medsebojno vplivanje razli\u010dnih sistemov. Tudi stati\u010dna elektrika predstavlja morebitno nevarnost.<\/p>\n

Komunikacijske antene se preizku\u0161ajo v jekleni kletki, ki prepre\u010duje vdor zunanjih televizijskih ali radijskih signalov. Stene so oblo\u017eene s posebnim materialom, tako da je v prostoru tako tiho kot v globokem vesolju.<\/p>","protected":false},"excerpt":{"rendered":"
