Imagina\u021bi-v\u0103 cum ar fi s\u0103 merge\u021bi \u00een spa\u021biu \u0219i s\u0103 zbura\u021bi \u00een jurul P\u0103m\u00e2ntului cu o vitez\u0103 de peste 27.000 km\/h! Aceasta este experien\u021ba pe care au tr\u0103it-o sute de astronau\u021bi \u00een ultimii 50 de ani. Plimb\u0103rile spa\u021biale (cunoscute oficial sub denumirea de activitate extravehicular\u0103 sau EVA) reprezint\u0103 o parte esen\u021bial\u0103 a activit\u0103\u021bii \u00een spa\u021biu. Acestea sunt utilizate pentru instalarea de echipamente \u0219i experimente noi, precum \u0219i pentru efectuarea de repara\u021bii. Au fost necesare aproape 1 000 de ore de plimb\u0103ri spa\u021biale pentru construirea \u0219i \u00eentre\u021binerea Sta\u021biei Spa\u021biale Interna\u021bionale \u00eencep\u00e2nd din 1998.<\/p>\n<\/div>\n

Astronau\u021bii care efectueaz\u0103 ie\u0219iri \u00een spa\u021biu poart\u0103 costume de protec\u021bie atunci c\u00e2nd intr\u0103 \u00een vidul spa\u021bial, lipsit de aer. Aceste costume au mai multe straturi care men\u021bin temperatura optim\u0103 a purt\u0103torilor, le permit s\u0103 respire \u0219i \u00eei protejeaz\u0103 de radia\u021biile nocive. Presiunea oxigenului din interiorul costumelor este mai mic\u0103 dec\u00e2t cea din Sta\u021bia Spa\u021bial\u0103. Prin urmare, astronau\u021bii trebuie s\u0103 petreac\u0103 aproximativ patru ore respir\u00e2nd oxigen \u00eentr-o camer\u0103 de echilibrare \u00eenainte de a putea ie\u0219i \u00een exterior.<\/p>\n

Pe ISS sunt depozitate dou\u0103 costume presurizate diferite. Costumul american are dou\u0103 sec\u021biuni: o parte superioar\u0103 rigid\u0103 a trunchiului \u0219i o parte inferioar\u0103 flexibil\u0103 a trunchiului. Aceste sec\u021biuni se \u00eembin\u0103 la talie. Picioarele astronautului sunt introduse \u00een pantaloni, apoi bra\u021bele \u0219i partea superioar\u0103 a corpului sunt a\u0219ezate \u00een sec\u021biunea superioar\u0103. Costumul rusesc are o sec\u021biune superioar\u0103 rigid\u0103, prev\u0103zut\u0103 cu o deschidere \u00een spate, care g\u0103zduie\u0219te \u0219i sistemul de sus\u021binere a vie\u021bii. Acest lucru faciliteaz\u0103 \u00eembr\u0103carea costumului cu o singur\u0103 m\u00e2n\u0103. Ambele costume au m\u0103nu\u0219i \u0219i c\u0103\u0219ti separate.<\/p>\n

Astronau\u021bii care efectueaz\u0103 ie\u0219iri \u00een spa\u021biu sunt adesea transporta\u021bi dintr-un loc \u00een altul la cap\u0103tul unui bra\u021b robotic. Exist\u0103, de asemenea, balustrade speciale care \u00eei ajut\u0103 s\u0103 se deplaseze. Pentru a \u00eempiedica plutirea lor \u00een spa\u021biu \u0219i pierderea \u00een spa\u021biu, ace\u0219tia sunt lega\u021bi de sta\u021bie cu ajutorul unor cabluri sub\u021biri. Plimb\u0103rile spa\u021biale pot dura multe ore. Recordul este de\u021binut de Susan Helms \u0219i James Voss, care au petrecut aproape 9 ore \u00een spa\u021biu \u00een martie 2001.<\/p>","protected":false},"excerpt":{"rendered":"
