\u00centr-un articol publicat pe site-ul ei oficial, NASA a subliniat numeroasele obstacole care trebuie s\u0103 fie dep\u0103\u015fite \u00eenainte ca primii oameni s\u0103 p\u0103\u015feasc\u0103 pe planeta Marte. “C\u00e2nd va putea omul s\u0103 ajung\u0103 pe Marte?” este \u00eentrebarea la care a dorit s\u0103 r\u0103spund\u0103 agen\u0163ia spa\u0163ial\u0103 american\u0103.<\/p>\n
De\u015fi acest lucru se \u00eent\u00e2mpl\u0103 \u00een cel mai recent film al regizorului Ridley Scott, “Mar\u0163ianul\/ The Martian”, lansat \u00een Statele Unite la sf\u00e2r\u015fitul s\u0103pt\u0103m\u00e2nii trecute, NASA a preferat o abordare realist\u0103 \u015fi afirm\u0103 c\u0103 va avea nevoie de timp \u00eenainte de a atinge acest obiectiv, gra\u0163ie noului ei plan de explorare spa\u0163ial\u0103.<\/p>\n
Un “obiectiv realizabil”, dar nu \u00eenainte de anii 2030 – \u00centr-un document oficial, redactat pe 36 de pagini, NASA afirm\u0103 c\u0103 poate “s\u0103 rezolve” dificult\u0103\u0163ile generate de un program at\u00e2t de ambi\u0163ios, \u00eens\u0103 nu a dezv\u0103luit nici data exact\u0103 de lansare a primei misiuni cu echipaj uman spre Marte, nici costurile unei astfel de misiuni. P\u00e2n\u0103 \u00een prezent, directorii de la NASA vorbesc \u00een termeni generali \u015fi spun c\u0103 obiectivul nu va putea fi atins \u00eenainte de anii 2030.<\/p>\n
D\u00e2nd totu\u015fi dovad\u0103 de optimism, adminstratorul general al NASA, Charles Bolden, a subliniat \u00eentr-un comunicat faptul c\u0103 “agen\u0163ia nu s-a aflat niciodat\u0103 at\u00e2t de aproape de a trimite astronau\u0163i pe Marte”, insist\u00e2nd pe importan\u0163a pe care o are pentru acest proiect cooperarea cu partenerii interna\u0163ionali \u015fi cu sectorul privat. “S\u0103 tr\u0103ie\u015fti \u00een spa\u0163iu necesit\u0103 acceptarea unor riscuri, dar ele merit\u0103 efortul”, a subliniat raportul agen\u0163iei americane, care vorbe\u015fte despre un “obiectiv realizabil”.<\/p>\n
Un mediu extrem de ostil pentru om – Pericolele sunt \u00eentr-adev\u0103r numeroase pe durata \u00eentregii misiuni spre Marte, ce ar putea s\u0103 \u00eei oblige pe astronau\u0163i s\u0103 petreac\u0103 \u00een spa\u0163iu o perioad\u0103 de trei ani. Pe l\u00e2ng\u0103 radia\u0163iile cosmice care sporesc considerabil riscul de cancer, absen\u0163a gravita\u0163iei pentru o perioad\u0103 at\u00e2t de \u00eendelungat\u0103 genereaz\u0103 o sc\u0103dere a densit\u0103\u0163ii osoase \u015fi a masei musculare \u015fi sl\u0103be\u015fte sistemul imunitar, reaminte\u015fte acela\u015fi document publicat de Agen\u0163ia spa\u0163ial\u0103 american\u0103. NASA trebuie s\u0103 conceap\u0103 \u015fi noi costume spa\u0163iale, asem\u0103n\u0103toare celor de scafandru, dar care s\u0103 fie adaptate condi\u0163iilor vitrege din spa\u0163iu, \u015fi s\u0103 pun\u0103 la punct un nou sistem de propulsie electric\u0103 pe baz\u0103 de energie solar\u0103, pentru viitorul modul spa\u0163ial care va c\u0103l\u0103tori spre planeta ro\u015fie.<\/p>\n
