Majoritatea navelor spa\u021biale ale ESA sunt testate la Centrul European de Cercetare \u0219i Tehnologie Spa\u021bial\u0103 (ESTEC) din \u021a\u0103rile de Jos. Centrul de testare al ESTEC dispune de tot ceea ce este necesar pentru verificarea unei nave spa\u021biale \u00eenainte ca aceasta s\u0103 fie transportat\u0103 la locul de lansare.<\/p>\n<\/div>\n

Simulatorul spa\u021bial de mari dimensiuni este denumit uneori \u2018spa\u021biul \u00eentr-o cutie\u2019. \u00cen interiorul camerei, un satelit este expus la condi\u021bii extreme, similare celor din spa\u021biu. Dup\u0103 ce aerul este pompat afar\u0103, temperatura satelitului poate varia de la 100 \u00b0C \u2013 punctul de fierbere al apei \u2013 p\u00e2n\u0103 la -100 \u00b0C, temperatura de \u00eenghe\u021b. O persoan\u0103 nu ar putea supravie\u021bui la astfel de temperaturi!<\/p>\n

Unele aparate speciale de testare verific\u0103 dac\u0103 satelitul poate rezista la vibra\u021bii puternice, \u00een special \u00een timpul lans\u0103rii. Cel mai mare aparat de testare din Europa este aparatul de testare multiaxial al ESA, denumit \u201eHydra\u201d.<\/p>\n

Centrul european de testare acustic\u0103 de mari dimensiuni se asigur\u0103 c\u0103 un satelit poate rezista zgomotului asurzitor generat de o lansare. Satelitul este supus unui flux sonor provenit de la difuzoare uria\u0219e.<\/p>\n

Alte teste asigur\u0103 func\u021bionarea corect\u0103 a echipamentelor electrice ale navei spa\u021biale. Se efectueaz\u0103 verific\u0103ri minu\u021bioase pentru a se asigura c\u0103 diferitele sisteme nu se influen\u021beaz\u0103 reciproc. Electricitatea static\u0103 reprezint\u0103, de asemenea, o posibil\u0103 amenin\u021bare.<\/p>\n

Antenele de comunica\u021bii sunt testate \u00eentr-o cu\u0219c\u0103 din o\u021bel care blocheaz\u0103 semnalele externe de televiziune sau radio. Pere\u021bii sunt c\u0103ptu\u0219i\u021bi cu un material special, astfel \u00eenc\u00e2t \u00eenc\u0103perea s\u0103 fie la fel de silen\u021bioas\u0103 ca spa\u021biul cosmic.<\/p>","protected":false},"excerpt":{"rendered":"
