Ena najve\u010djih gro\u017eenj za zdravje astronavtov je vesoljsko sevanje. Energijski delci, ki potujejo skozi vesolje s hitrostjo, ki se pribli\u017euje hitrosti svetlobe, lahko povzro\u010dijo veliko \u0161kodo telesnim celicam, kar znatno pove\u010da tveganje za nastanek raka. Da bi ugotovili, kako najbolje za\u0161\u010dititi \u010dlane posadke pred tem bombardiranjem, ESA v sodelovanju z nem\u0161kim centrom preizku\u0161a razli\u010dne vrste za\u0161\u010dite, vklju\u010dno z lunino in marsovsko prstjo.<\/p>\n<\/div>\n

Vesolje je polno nabitih delcev, kar pomeni, da so astronavti uradno uvr\u0161\u010deni med delavce, izpostavljene sevanju. Nekateri delci izvirajo iz mo\u010dnih, a kratkotrajnih son\u010dnih nevih. Drugi, znani kot kozmi\u010dni \u017earki, nastajajo v umirajo\u010dih zvezdah v oddaljenih galaksijah.<\/p>\n

Trenutno vesoljsko sevanje ne predstavlja ve\u010djega problema, saj Mednarodna vesoljska postaja kro\u017ei znotraj zemeljskega magnetnega polja. To magnetno polje deluje kot \u0161\u010dit pred ve\u010dino vesoljskega sevanja. Vendar pa bodo posadke, ki bodo potovale na Luno in Mars, veliko bolj izpostavljene nevarnosti visokoenergijskega kozmi\u010dnega sevanja, zato bo potrebno posebno za\u0161\u010dito.<\/p>\n

Ekipa ESA uporablja pospe\u0161evalnik delcev GSI v Darmstadtu v Nem\u010diji za testiranje potencialnih materialov za za\u0161\u010dito. Med testiranimi materiali so aluminij, voda, polietilenska plastika, ve\u010dplastne strukture ter simulirani materiali z Lune in Marsa.<\/p>\n

Gostej\u0161a in debelej\u0161a za\u0161\u010dita pred sevanjem ni vedno bolj\u0161a. Kozmi\u010dni \u017earki, ki udarijo v kovinske \u0161\u010dite, lahko povzro\u010dijo plohi sekundarnih delcev, ki so lahko \u0161e bolj \u0161kodljivi. Na splo\u0161no la\u017eji materiali, kot sta voda in plastika, zagotavljajo bolj\u0161o za\u0161\u010dito. Novi materiali, bogati z vodikom, ki jih je razvilo podjetje v Veliki Britaniji, se zaenkrat zdijo zelo obetavni.<\/p>","protected":false},"excerpt":{"rendered":"
