Euroopan kaikkien aikojen painavin avaruusalus on valmis l\u00e4ht\u00f6\u00f6n Kouroun avaruuskeskuksesta Ranskan Guayanasta. ESA:n toinen Automated Transfer Vehicle (ATV) -aluksesta laukaistaan kohti Kansainv\u00e4list\u00e4 avaruusasemaa (ISS) Ariane 5 -raketilla keskiviikkona 16. helmikuuta klo 22.50 CET.<\/p>\n<\/div>\n

Rahtialus toimittaa miehist\u00f6lle v\u00e4ltt\u00e4m\u00e4tt\u00f6mi\u00e4 tarvikkeita ja nostaa avaruusaseman kiertorataa. Sen teht\u00e4v\u00e4 kest\u00e4\u00e4 kolme ja puoli kuukautta. Kahdeksan p\u00e4iv\u00e4n lennon j\u00e4lkeen ATV saavuttaa valtavan avaruusaseman ja suorittaa automaattisen telakoitumisen 23. helmikuuta.<\/p>\n

ATV-2 on nimetty kuuluisan saksalaisen t\u00e4htitieteilij\u00e4n Johannes Keplerin mukaan, joka eli 1600-luvulla. Se on ensimm\u00e4inen k\u00e4ytt\u00f6\u00f6notettu ATV-alus, joka seurasi vuonna 2008 toteutettua, eritt\u00e4in onnistunutta Jules Verne -kokeilulentoa. Sen kokonaislaukaisumassa on yli 20 tonnia, ja se on lastattu 7 tonnilla rahtia. Lastiin kuuluu 4,5 tonnia polttoainetta, jonka avulla ATV voi s\u00e4\u00e4t\u00e4\u00e4 ISS:n asentoa ja nostaa sen kiertorataa ajoittain. ATV:n hy\u00f6tykuormaan kuuluu my\u00f6s l\u00e4hes 1 600 kg kuivarahtia, 850 kg polttoainetta Ven\u00e4j\u00e4n Zvezda-moduulille sek\u00e4 100 kg happea!<\/p>\n

T\u00e4ll\u00e4 lennolla ei toimiteta juomavett\u00e4, koska ISS:ll\u00e4 on jo runsaasti vett\u00e4. Vesis\u00e4ili\u00f6t t\u00e4ytet\u00e4\u00e4n kuitenkin asemalta per\u00e4isin olevalla nestem\u00e4isell\u00e4 j\u00e4tteell\u00e4 ennen kuin ATV irtoaa ISS:st\u00e4 kes\u00e4kuussa. Miehist\u00f6 lastaa alukseen my\u00f6s j\u00e4tepussit ja tarpeettomat laitteet. ATV poistetaan sitten kiertoradalta etel\u00e4isen Tyynenmeren yll\u00e4, ja se palaa ilmakeh\u00e4ss\u00e4.<\/p>\n
