Avaruus on niin valtava, ett\u00e4 edestakainen matka Marsiin, joka on yksi l\u00e4himmist\u00e4 planeetoista, kest\u00e4\u00e4 useita vuosia. Ennen kuin voimme l\u00e4hett\u00e4\u00e4 astronautteja niin pitkille ja vaarallisille matkoille, on hyv\u00e4 selvitt\u00e4\u00e4 mahdollisimman paljon niist\u00e4 ongelmista, jotka heid\u00e4n on ylitett\u00e4v\u00e4. Siksi ESA aikoo tehd\u00e4 yhteisty\u00f6t\u00e4 ven\u00e4l\u00e4isten kanssa ja l\u00e4hett\u00e4\u00e4 kuusihenkisen miehist\u00f6n Marsiin kev\u00e4\u00e4ll\u00e4 2008.<\/p>\n<\/div>\n

Ei, kyseess\u00e4 ei ole oikea avaruuslento. Se on itse asiassa simuloitu lento, joka tunnetaan nimell\u00e4 Mars500. \u2018Matkan\u2019 aikana miehist\u00f6 viett\u00e4\u00e4 500 p\u00e4iv\u00e4\u00e4 asuen ja ty\u00f6skennellen erityisess\u00e4 eristyslaitoksessa Moskovassa. Metallis\u00e4ili\u00f6ihin suljettuina vapaaehtoiset joutuvat kokemaan monia tilanteita, joita he todellisuudessa kohtaavat matkallaan Punaiselle planeetalle. T\u00e4m\u00e4 tarkoittaa, ett\u00e4 heid\u00e4n on \u2018koettava\u2019 laukaisu, jopa 250 p\u00e4iv\u00e4\u00e4 kest\u00e4v\u00e4 matka sinne, retki Marsin pinnalle ja pitk\u00e4 paluumatka kotiin.<\/p>\n

ESA etsii nyt tieteellisi\u00e4 kokeita, joiden avulla voimme oppia lis\u00e4\u00e4 t\u00e4llaisen pitk\u00e4n avaruuslennon aiheuttamista henkisist\u00e4 ja fyysisist\u00e4 rasituksista sek\u00e4 siit\u00e4, miten ne voitaisiin voittaa. Miten he esimerkiksi selvi\u00e4v\u00e4t el\u00e4m\u00e4st\u00e4 kaukana kotoa ahtaissa olosuhteissa? Kuinka he selvi\u00e4v\u00e4t \u00e4killisist\u00e4 h\u00e4t\u00e4tilanteista ja jopa 20 minuutin viiveist\u00e4 viestinn\u00e4ss\u00e4 kumpaankin suuntaan? Pystyv\u00e4tk\u00f6 he selviytym\u00e4\u00e4n rajoitetulla m\u00e4\u00e4r\u00e4ll\u00e4 ruokaa ja juomaa ilman toivoa lis\u00e4varusteiden saamisesta? K\u00e4rsiv\u00e4tk\u00f6 he mielialanvaihteluista ja unettomuudesta? Alkavatko he riidell\u00e4 ja tulla toisiinsa? Seuraa tilannetta t\u00e4\u00e4lt\u00e4.<\/p>","protected":false},"excerpt":{"rendered":"
