Marsille, Venukselle ja Titanille suuntautuneiden eritt\u00e4in menestyksekk\u00e4iden avaruuslentojensa j\u00e4lkeen Eurooppa aikoo tutkia Merkuriusta, joka on Aurinkoon l\u00e4hinn\u00e4 sijaitseva planeetta.<\/p>\n<\/div>\n

BepiColombo, joka on nimetty kuuluisan italialaisen matemaatikon mukaan, joka tutki parasta lentorataa Merkuriukseen, tulee olemaan yksi kaikkien aikojen monimutkaisimmista avaruuslennoista. Aurinkokunnan pienimm\u00e4lle planeetalle l\u00e4hetet\u00e4\u00e4n kolme moduulia: eurooppalainen kiertolainen, japanilainen kiertolainen sek\u00e4 ty\u00f6nt\u00f6voimayksikk\u00f6, joka kuljettaa n\u00e4m\u00e4 kaksi avaruusaluksia Merkuriukseen.<\/p>\n

Miksi l\u00e4hte\u00e4 Merkuriukseen? T\u00e4h\u00e4n menness\u00e4 vain kaksi avaruusluotainta on vieraillut planeetalla, ja suurta osaa sen pinnasta ei ole viel\u00e4 tutkittu yksityiskohtaisesti. BepiColombo-luotaimella on viel\u00e4 monia kysymyksi\u00e4, joihin on l\u00f6ydett\u00e4v\u00e4 vastaus. Esimerkiksi: miksi Merkurius koostuu p\u00e4\u00e4asiassa raudasta? Miksi sill\u00e4 on magneettikentt\u00e4? Onko sen napojen l\u00e4hell\u00e4 sijaitsevissa kylmiss\u00e4, varjoisissa kraattereissa vesij\u00e4\u00e4t\u00e4?<\/p>\n

ESAn Mercury Planetary Orbiter -luotain kuljettaa mukanaan 11 mittauslaitetta. N\u00e4m\u00e4 laitteet kartoittavat planeetan pintaa polaariselta kiertoradalta k\u00e4sin, tutkivat sen sis\u00e4osan rakennetta, mittaavat kivilajien koostumusta ja tutkivat planeetan ohutta ilmakeh\u00e4\u00e4. Toinen avaruusalus, Japanin Mercury Magnetospheric Orbiter, kuljettaa mukanaan viisi mittauslaitetta, joilla tutkitaan planeetan magneettikentt\u00e4\u00e4.<\/p>\n

BepiColombo on ensimm\u00e4inen t\u00e4m\u00e4n salaper\u00e4isen planeetan tutkimusluotain, joka koostuu kahdesta kiertolaitteesta. Laukaisun on m\u00e4\u00e4r\u00e4 tapahtua hein\u00e4kuussa 2016. Pitk\u00e4n ja mutkikkaan matkan j\u00e4lkeen aurinkokunnan sis\u00e4osien l\u00e4pi BepiColombo saapuu Merkuriukselle vuonna 2024.<\/p>","protected":false},"excerpt":{"rendered":"
