En rummission kan vare alt fra en uge til seks m\u00e5neder, men hvad sker der, n\u00e5r bes\u00e6tningen vender tilbage til Jorden? Inden for f\u00e5 timer overf\u00f8res de fra et v\u00e6gtl\u00f8st milj\u00f8 til normal tyngdekraft. I stedet for at leve et sted, hvor alt har tendens til at sv\u00e6ve, vender de tilbage til en planet, hvor hver eneste bev\u00e6gelse kr\u00e6ver en indsats.<\/p>\n<\/div>\n

Det er sv\u00e6rt at v\u00e6nne sig til Jordens tyngdekraft igen, fordi deres muskler og knogler er blevet svagere, og hjertet skal arbejde meget h\u00e5rdere for at pumpe blodet rundt i kroppen. Astronauter, der vender tilbage i et Sojuz-rumfart\u00f8j, skal hj\u00e6lpes ud af russisk redningspersonale, og de b\u00e6res ud til de ventende helikoptere, der skal flyve dem den f\u00f8rste del af rejsen hjem.<\/p>\n

Selv dem, der flyver tilbage med rumf\u00e6rgen, f\u00f8ler sig ofte svimle. Nogle kan besvime. De har ogs\u00e5 sv\u00e6rt ved at st\u00e5 op, g\u00e5, dreje rundt om hj\u00f8rner og bevare balancen. Hvis de lukker \u00f8jnene, risikerer de at falde om. Selv det kan v\u00e6re sv\u00e6rt at sove. Nogle kosmonauter har fortalt, at de m\u00e5neder efter deres flyvning nogle gange taber en kop eller en anden genstand i luften \u2013 og bliver chokerede, n\u00e5r den smadrer ned p\u00e5 gulvet! Det kan tage tre til fire dage at v\u00e6nne sig til det igen efter korte flyvninger, men fire uger eller mere efter et seks m\u00e5neders ophold p\u00e5 Den Internationale Rumstation.<\/p>\n

Andre bivirkninger tager meget l\u00e6ngere tid at overvinde. Faldet i knoglet\u00e6thed medf\u00f8rer en \u00f8get risiko for knoglebrud. De sv\u00e6kkede muskler g\u00f8r det sv\u00e6rere at l\u00f8fte selv lette genstande eller udf\u00f8re dagligdags aktiviteter. Men rumfartens vidundere er sv\u00e6re at modst\u00e5. Otte personer har v\u00e6ret i rummet mindst seks gange. Russeren Valeri Polyakov tilbragte 240 dage i kredsl\u00f8b, og f\u00e5 \u00e5r senere vendte han tilbage til rummet i yderligere 437 dage!<\/p>","protected":false},"excerpt":{"rendered":"
