En af de st\u00f8rste trusler mod astronauternes helbred er rumstr\u00e5ling. Energirige partikler, der bev\u00e6ger sig gennem rummet med n\u00e6sten lysets hastighed, kan for\u00e5rsage alvorlige skader p\u00e5 kroppens celler, hvilket medf\u00f8rer en langt st\u00f8rre risiko for kr\u00e6ft. For at finde ud af, hvordan bes\u00e6tningsmedlemmerne bedst kan beskyttes mod denne str\u00e5ling, samarbejder ESA med et center i Tyskland om at teste forskellige former for afsk\u00e6rmning, herunder jord fra M\u00e5nen og Mars.<\/p>\n<\/div>\n

Rummet er fyldt med ladede partikler, hvilket betyder, at astronauter officielt betragtes som str\u00e5lingsarbejdere. Nogle af partiklerne stammer fra intense, men kortvarige solstorme. Andre, de s\u00e5kaldte kosmiske str\u00e5ler, dannes af d\u00f8ende stjerner i fjerne galakser.<\/p>\n

I \u00f8jeblikket udg\u00f8r rumstr\u00e5ling ikke noget st\u00f8rre problem, da Den Internationale Rumstation kredser inden for Jordens magnetfelt. Dette magnetfelt fungerer som et skjold mod det meste af rumstr\u00e5lingen. Bes\u00e6tninger, der rejser til M\u00e5nen og Mars, vil imidlertid v\u00e6re udsat for en langt st\u00f8rre risiko fra h\u00f8jenergisk kosmisk str\u00e5ling, og derfor vil der v\u00e6re behov for s\u00e6rlig afsk\u00e6rmning.<\/p>\n

ESA-teamet benytter GSI-partikelacceleratoren i Darmstadt, Tyskland, til at teste mulige afsk\u00e6rmningsmaterialer. Blandt de testede materialer er aluminium, vand, polyethylenplast, flerlagsstrukturer samt simuleret materiale fra M\u00e5nen og Mars.<\/p>\n

En t\u00e6ttere og tykkere str\u00e5lingsafsk\u00e6rmning er ikke altid bedre. Kosmiske str\u00e5ler, der rammer metalsk\u00e6rme, kan frembringe regnskyl af sekund\u00e6re partikler, som kan v\u00e6re endnu mere skadelige. Generelt giver lettere materialer som vand og plast bedre beskyttelse. Nye, brintrige materialer, der er udviklet af en virksomhed i Storbritannien, ser indtil videre meget lovende ud.<\/p>","protected":false},"excerpt":{"rendered":"
