N\u00e5r mennesket en dag rejser til Mars, venter der dem en helt enest\u00e5ende rejse. Forskere har analyseret, hvad der skete under den simulerede Mars500-mission i 2010\u20132011, hvilket har givet dem et langt bedre indblik i de psykiske og fysiske problemer, der kan opst\u00e5 under en Mars-mission.<\/p>\n<\/div>\n

Bes\u00e6tningen best\u00e5ende af seks \u2018marsonauter\u2019 blev sp\u00e6rret inde i et simuleret rumskib n\u00e6r Moskva i Rusland i 520 dage. Det svarer til at v\u00e6re sp\u00e6rret inde i n\u00e6sten halvandet \u00e5r! Det er den tid, det vil tage at flyve til Mars og tilbage, plus 30 dage til at udforske overfladen. Under deres \u2018mission\u2019 levede bes\u00e6tningen i isolation uden friske f\u00f8devarer, sollys eller frisk luft. Unders\u00f8gelsen viste, at hver eneste detalje skal planl\u00e6gges, herunder kost og s\u00f8vn.<\/p>\n

Da de ikke kunne se solen p\u00e5 himlen, var de frivillige n\u00f8dt til at finde andre m\u00e5der at regulere deres s\u00f8vnrytme p\u00e5, f.eks. ved at kigge p\u00e5 deres ure eller blive v\u00e6kket af andre bes\u00e6tningsmedlemmer. Der opstod dog problemer, fordi bes\u00e6tningsmedlemmerne sov p\u00e5 forskellige tidspunkter.<\/p>\n

ESA-forskerne forts\u00e6tter med at unders\u00f8ge problemet med at f\u00e5 en god nats s\u00f8vn. ESA-astronauten Luca Parmitano vil m\u00e5le hormoner, der er forbundet med s\u00f8vn, under sit seks m\u00e5neders ophold p\u00e5 Den Internationale Rumstation i \u00e5r. Man unders\u00f8ger ogs\u00e5 s\u00f8vnm\u00f8nstrene hos de mennesker, der bor p\u00e5 Concordia-basen i Antarktis under den lange, m\u00f8rke polare vinter.<\/p>\n

Andre overraskende resultater fra den simulerede Mars-mission viser, at vores kroppe ikke optager og udskiller salt konstant. Det ser ud til, at vores nyrer behandler salt i en ugentlig cyklus, hvor de nogle dage arbejder h\u00e5rdere for at udskille salt end andre. Disse resultater vil ikke kun komme astronauter i rummet til gode, men ogs\u00e5 alle p\u00e5 Jorden, der arbejder uregelm\u00e6ssige arbejdstider, har s\u00f8vnproblemer eller lider af saltrelateret forh\u00f8jet blodtryk.<\/p>","protected":false},"excerpt":{"rendered":"
