Forestil dig at g\u00e5 i rummet og flyve rundt om Jorden med en hastighed p\u00e5 over 27.000 km\/t! Det er netop det, som hundredvis af rumvandrere har oplevet i l\u00f8bet af de sidste 50 \u00e5r. Rumvandringer (officielt kaldet Extravehicular Activity eller EVA) er en vigtig del af arbejdet i rummet. De bruges til at installere nyt udstyr og eksperimenter samt til at udf\u00f8re reparationer. Der har v\u00e6ret behov for n\u00e6sten 1.000 timers rumvandringer for at opf\u00f8re og vedligeholde Den Internationale Rumstation siden 1998.<\/p>\n<\/div>\n

Rumvandrere b\u00e6rer beskyttelsesdragter, n\u00e5r de begiver sig ud i det luftl\u00f8se vakuum i rummet. Disse dragter best\u00e5r af mange forskellige lag, som holder b\u00e6reren p\u00e5 den rette temperatur, g\u00f8r det muligt for dem at tr\u00e6kke vejret og beskytter dem mod skadelig str\u00e5ling. Oxygentrykket inde i dragterne er lavere end i rumstationen. Derfor er astronauterne n\u00f8dt til at tilbringe omkring fire timer med at ind\u00e5nde ilt inde i en luftsluse, f\u00f8r de kan tr\u00e6de ud.<\/p>\n

Der opbevares to forskellige trykdragter p\u00e5 ISS. Den amerikanske dragt best\u00e5r af to dele: en stiv overkrop og en fleksibel underkrop. Disse dele samles i taljen. Astronautens ben stikkes ned i bukserne, hvorefter armene og overkroppen placeres i den \u00f8verste del. Den russiske dragt har en stiv overdel med en bagd\u00f8r, der ogs\u00e5 rummer livsst\u00f8ttesystemet. Dette g\u00f8r det lettere at tage dragten p\u00e5 med \u00e9n h\u00e5nd. Begge dragter har separate handsker og hjelme.<\/p>\n

Rumvandrere bliver ofte transporteret fra sted til sted ved hj\u00e6lp af en robotarm. Der findes ogs\u00e5 specielle gel\u00e6ndere, der hj\u00e6lper dem med at bev\u00e6ge sig rundt. For at forhindre, at de driver v\u00e6k og forsvinder ud i rummet, er de fastgjort til rumstationen med tynde reb. Rumvandringer kan vare i mange timer. Rekorden indehaves af Susan Helms og James Voss, der tilbragte n\u00e6sten 9 timer i rummet i marts 2001.<\/p>","protected":false},"excerpt":{"rendered":"
