Predstavljajte si, da hodite v vesolju in letite okoli Zemlje s hitrostjo ve\u010d kot 27.000 km\/h! To so v zadnjih 50 letih do\u017eiveli na stotine vesoljskih hodcev. Vesoljski sprehodi (uradno znani kot dejavnosti zunaj plovila ali EVA) so bistveni del dela v vesolju. Uporabljajo se za namestitev nove opreme in eksperimentov ter za izvajanje popravil. Za gradnjo in vzdr\u017eevanje Mednarodne vesoljske postaje od leta 1998 je bilo potrebnih skoraj 1.000 ur vesoljskih sprehodov.<\/p>\n<\/div>\n

Astronavti, ki opravljajo vesoljske sprehodi, nosijo za\u0161\u010ditne obleke, ko vstopijo v brez-zra\u010dni vakuum vesolja. Te obleke imajo veliko razli\u010dnih plasti, ki nosilcem zagotavljajo ustrezno temperaturo, omogo\u010dajo dihanje in jih \u0161\u010ditijo pred \u0161kodljivim sevanjem. Tlak kisika znotraj oblek je ni\u017eji kot v vesoljski postaji. Zato morajo astronavti pred izstopom v vesolje pribli\u017eno \u0161tiri ure dihati kisik v zra\u010dni komori.<\/p>\n

Na ISS sta shranjeni dve razli\u010dni tla\u010dni obleki. Ameri\u0161ka obleka ima dva dela: trden zgornji del trupa in pro\u017een spodnji del trupa. Ti deli se spojita v pasu. Astronavt najprej vtakne noge v hla\u010de, nato pa roke in zgornji del telesa v zgornji del obleke. Ruski skafander ima trden zgornji del z zadnjimi vrati, v katerih je name\u0161\u010den tudi sistem za ohranjanje \u017eivljenja. To olaj\u0161a obla\u010denje z eno roko. Oba skafandra imata lo\u010dene rokavice in \u010delade.<\/p>\n

Astronavti, ki opravljajo vesoljske sprehodi, se pogosto preva\u017eajo z enega mesta na drugo na koncu robotske roke. Na voljo so tudi posebna vodila, ki jim pomagajo pri gibanju. Da ne bi odplavali in se izgubili v vesolju, so s postajo povezani s tankimi vrvicami. Vesoljski sprehodi lahko trajajo ve\u010d ur. Rekord imata Susan Helms in James Voss, ki sta marca 2001 v vesolju pre\u017eivela skoraj 9 ur.<\/p>","protected":false},"excerpt":{"rendered":"
