13. tammikuuta ESA:n astronautti Thomas Pesquet l\u00e4htee kansainv\u00e4liselt\u00e4 avaruusasemalta avaruusk\u00e4velylle! Huipputeknisell\u00e4 avaruuspuvulla varustettuna Thomasin avaruusk\u00e4vely kest\u00e4\u00e4 jopa seitsem\u00e4n tuntia. H\u00e4nen seuranaan on ISS:n komentaja Shane Kimbrough.<\/p>\n<\/div>\n

Thomasin ja Shanen avaruusk\u00e4vely ei kuitenkaan ole pelkk\u00e4\u00e4 huvia. Heill\u00e4 on nimitt\u00e4in t\u00e4rke\u00e4 teht\u00e4v\u00e4: vanhojen akkujen vaihtaminen uusiin, paranneltuihin akkuihin. N\u00e4m\u00e4 akut varastoivat ISS:n aurinkopaneelien tuottamaa energiaa. Kun ISS on Maan p\u00e4iv\u00e4puolella, energiaa tuotetaan runsaasti. Mutta kun ISS on Maan pime\u00e4ll\u00e4 puolella, aurinkopaneelit eiv\u00e4t saa lainkaan auringonvaloa. T\u00e4n\u00e4 aikana ISS toimii akkuihin varastoidulla energialla. Akut ladataan sitten uudelleen, kun aurinkopaneelit ovat j\u00e4lleen auringonvalossa. Tehokkaiden akkujen merkitys on siis elint\u00e4rke\u00e4!<\/p>\n

Thomas ja Shane saavat apua radioyhteyden kautta NASA:n lentokeskusesta Houstonista, Yhdysvalloista. Siell\u00e4 ESA:n astronautti Luca Parmitano antaa neuvoja kahdelle avaruusk\u00e4velij\u00e4lle ja opastaa heit\u00e4 monimutkaisten teht\u00e4vien suorittamisessa. Luca on erinomainen valinta t\u00e4h\u00e4n teht\u00e4v\u00e4\u00e4n, sill\u00e4 h\u00e4n on itse suorittanut kaksi avaruusk\u00e4vely\u00e4.<\/p>\n

Thomas on jo alkanut valmistella avaruuspukuaan sek\u00e4 ker\u00e4t\u00e4 ty\u00f6kaluja ja varusteita, joita h\u00e4n ja Shane tulevat tarvitsemaan. Ep\u00e4ilem\u00e4tt\u00e4 h\u00e4n odottaa innolla my\u00f6s upeaa n\u00e4kym\u00e4\u00e4, jonka h\u00e4n p\u00e4\u00e4see nauttimaan Maasta ja ISS:st\u00e4!<\/p>\n
