Kansainv\u00e4linen avaruusasema (ISS) on kuin saari, jota ymp\u00e4r\u00f6i tyhj\u00e4 meri. Ilman s\u00e4\u00e4nn\u00f6llist\u00e4 huoltoreitti\u00e4 Maasta sen miehist\u00f6t olisivat kuin nykyaikaisia Robinson Crusoeja \u2013 kaukana kotoa jumissa.<\/p>\n<\/div>\n

T\u00e4ll\u00e4 hetkell\u00e4 astronautit eiv\u00e4t voi viljell\u00e4 omaa ruokaa kiertoradalla. He ovat riippuvaisia muutaman kuukauden v\u00e4lein saapuvista tuoreista tarviketoimituksista.<\/p>\n

Viel\u00e4 \u00e4skett\u00e4in miehist\u00f6jen tarvitsemat ruoka, vesi, ilma ja varaosat toimitettiin Yhdysvaltain avaruussukkulan ja ven\u00e4l\u00e4isten miehitt\u00e4m\u00e4tt\u00f6mien Progress-aluksien avulla. Tilanne muuttui vuonna 2008, kun uusi huoltoalus \u2013 ESA:n Automated Transfer Vehicle (ATV) \u2013 teki ensilentonsa. ATV, joka nimettiin kuuluisan ranskalaisen tieteiskirjailijan Jules Vernen mukaan, telakoitui ISS:\u00e4\u00e4n 3. huhtikuuta. Kun sen teht\u00e4v\u00e4 oli suoritettu, se l\u00e4hetettiin ilmakeh\u00e4\u00e4n, jossa se paloi loppuun 29. syyskuuta.<\/p>\n

Jokainen ATV laukaistaan avaruuteen Euroopan Ariane-5-raketilla. Lento kansainv\u00e4liselle avaruusasemalle (ISS) kest\u00e4\u00e4 yleens\u00e4 viisi p\u00e4iv\u00e4\u00e4.<\/p>\n

\"The
Automaattisen siirtoaluksen (ATV) avulla ESA voi kuljettaa hy\u00f6tykuormia kansainv\u00e4liselle avaruusasemalle<\/figcaption><\/figure>\n

20 tonnin painoinen ATV kuljettaa jopa 8 tonnia tarvikkeita, polttoainetta, kokeita ja lahjoja miehist\u00f6lle. Kuuden kuukauden ajan, jonka se on telakoituna ISS:\u00e4\u00e4n, sen moottoria voidaan k\u00e4ytt\u00e4\u00e4 aseman kiertoradan korottamiseen. T\u00e4m\u00e4 pit\u00e4\u00e4 ISS:n turvallisella noin 320 km:n korkeudella, selv\u00e4sti maapallon ilmakeh\u00e4n yl\u00e4puolella.<\/p>\n
