Siit\u00e4 l\u00e4htien seikkailumme Maan ulkopuolella ovat jatkuneet, mutta niiss\u00e4 on p\u00e4\u00e4asiassa ollut mukana robottitutkijoita. T\u00e4m\u00e4 johtuu siit\u00e4, ett\u00e4 miehitetyt avaruuslennot ovat haastavia. Meid\u00e4n ei tarvitse vain l\u00e4hett\u00e4\u00e4 ihmisi\u00e4 avaruuteen, vaan meid\u00e4n on my\u00f6s tuotava heid\u00e4t turvallisesti takaisin kotiin, ja se on eritt\u00e4in haastavaa.<\/p>\n<\/div>\n<p>Onneksi kaikille, jotka haaveilevat avaruusmatkasta, Euroopan avaruusj\u00e4rjest\u00f6 ty\u00f6skentelee ahkerasti uuden \u201cavaruustaksin\u201d kehitt\u00e4miseksi. Avaruusalus on nimelt\u00e4\u00e4n IXV (lausutaan EYE-EX-VEE), ja se on suunniteltu antamaan meille lis\u00e4\u00e4 tietoa siit\u00e4, miten voidaan suunnitella avaruusaluksia, jotka pystyv\u00e4t tutkimaan avaruutta ja palaamaan takaisin Maahan. Jonain p\u00e4iv\u00e4n\u00e4 se voisi kuljettaa astronautteja kansainv\u00e4liselle avaruusasemalle ja sielt\u00e4 takaisin \u2013 ja ehk\u00e4 jonain p\u00e4iv\u00e4n\u00e4 jopa kauemmaskin!<\/p>\n<p>Siipet\u00f6n avaruuslentokone laukaistaan Vega-raketilla 11. helmikuuta.

Se nousee yli 400 kilometrin korkeuteen maanpinnasta ja saavuttaa 27 000 kilometrin tuntinopeuden \u2013 85 kertaa nopeammin kuin luotijuna!
