Andreas Mogensen on palannut Maahan! Andreas laskeutui turvallisesti lauantaiaamun varhaisina tunteina lyhyen, 10 p\u00e4iv\u00e4\u00e4 kest\u00e4neen teht\u00e4v\u00e4ns\u00e4 j\u00e4lkeen Kansainv\u00e4lisell\u00e4 avaruusasemalla (ISS).<\/p>\n<\/div>\n

Andreas l\u00e4hetettiin kiertoradalle 2. syyskuuta, ja h\u00e4nest\u00e4 tuli Tanskan ensimm\u00e4inen astronautti. Vaikka h\u00e4nen teht\u00e4v\u00e4ns\u00e4 oli lyhyt, se oli t\u00e4ynn\u00e4 j\u00e4nnitt\u00e4vi\u00e4 tieteellisi\u00e4 kokeita.<\/p>\n

Andreas testasi erityist\u00e4 uutta vedensuodatinta, joka on suunniteltu muuttamaan likainen j\u00e4tevesi puhtaaksi juomavedeksi ilman mink\u00e4\u00e4nlaista energiankulutusta. Jos t\u00e4m\u00e4 uusi teknologia osoittautuu toimivaksi, siit\u00e4 on hy\u00f6ty\u00e4 sek\u00e4 avaruusasemalla ett\u00e4 Maassa.<\/p>\n

Toisessa kokeessa Andreasilla oli yll\u00e4\u00e4n niin sanottu SkinSuit. T\u00e4m\u00e4 tiukasti istuva puku on suunniteltu est\u00e4m\u00e4\u00e4n astronauttien selk\u00e4rangan venymist\u00e4 painovoimattomassa tilassa. Koska avaruudessa ei ole painovoimaa, joka painaisi astronautin selk\u00e4rankaa alasp\u00e4in, se voi veny\u00e4 jopa l\u00e4hes 8 cm!<\/p>\n

Mutta uskokaa tai \u00e4lk\u00e4\u00e4, h\u00e4nen vaikuttavin saavutuksensa oli tapin asettaminen reik\u00e4\u00e4n. T\u00e4m\u00e4 ei ehk\u00e4 kuulosta vaikealta, mutta Andreas teki sen k\u00e4ytt\u00e4m\u00e4ll\u00e4 robottia, jota ohjattiin et\u00e4ohjauksella tuhansien kilometrien p\u00e4\u00e4st\u00e4! Mobiilirobotti sijaitsi Alankomaissa, kun taas Andreas oli 400 kilometri\u00e4 maanpinnan yl\u00e4puolella ISS:n kyydiss\u00e4.<\/p>\n

Tulevaisuudessa Andreasin harjoittelemat tekniikat voisivat olla hy\u00f6dyksi muiden planeettojen kiertoradalla oleville astronautille, kun he suorittavat kokeita robottien avulla planeettojen pinnalla.<\/p>\n

Mielenkiintoinen fakta:<\/b> Andreas otti kansainv\u00e4liselt\u00e4 avaruusasemalta (ISS) ensimm\u00e4iset kuvat myrskypilvist\u00e4 purkautuvista sinisist\u00e4 salamoista. Katso h\u00e4nen videonsa Intian yl\u00e4puolella raivoavasta ukkosmyrskyst\u00e4 t\u00e4\u00e4ll\u00e4<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
