5\u00bd aastat p\u00e4rast starti Prantsuse Guajaanast on ESA komeedij\u00e4litaja Rosetta naasnud kodule l\u00fchikeseks k\u00fclastuseks. 13. novembri hommikul kinnitasid juhtimiskeskuse t\u00f6\u00f6tajad Darmstadtis, Saksamaal, et Rosetta oli edukalt l\u00e4binud oma viimase Maa-l\u00e4hedase m\u00f6\u00f6dalennu.<\/p>\n<\/div>\n

Kiirusega 13,34 km\/s m\u00f6\u00f6dus kosmoselaev planeedist 2 481 km k\u00f5rgusel. L\u00e4him l\u00e4henemine toimus kell 08:45:40 Kesk-Euroopa aja j\u00e4rgi, veidi l\u00f5una pool Indoneesia saart Jaavat. See neljas kohtumine planeediga andis 3-tonnisele uurimisaparaadile piisavalt energiat, et l\u00e4bida asteroidi v\u00f6\u00f6 ja kohtuda komeediga T\u0161urjumov-Gerasimenko.<\/p>\n

Rosetta v\u00f5ib aidata lahendada ka \u00fcht pikaajalist m\u00f5istatust. Aastate jooksul on m\u00f5ned kosmoses\u00f5idukid (sealhulgas Rosetta) Maa m\u00f6\u00f6dumisel kogenud v\u00e4ikest \u2013 kuid ootamatut \u2013 kiiruse muutust. Seni pole keegi suutnud sellele head selgitust leida.<\/p>\n

Teadlased kasutasid m\u00f6\u00f6dalendu \u00e4ra, et l\u00fclitada sisse m\u00f5ned Rosetta instrumendid. Esimesed pildid n\u00e4itasid \u00f5hukest poolkuud, mille suurus kasvas j\u00e4rk-j\u00e4rgult, kui kosmoselaev kiirustas Maa poole. Hilisemad pildid n\u00e4itasid \u00f6\u00f6sel s\u00e4ravaid linnatulesid ning keerlevaid pilvi P\u00f5hja-Ameerika ja Vaikse ookeani kohal. Teised instrumendid uurisid planeedi atmosf\u00e4\u00e4ri ja magnetv\u00e4lja ning otsisid vee j\u00e4lgi Kuult.<\/p>\n

Rosetta on n\u00fc\u00fcd l\u00e4binud umbes 4 500 miljonit km oma 7 100 miljoni km pikkusest teekonnast komeedi poole. Viimane m\u00f6\u00f6dalend Maa juurest suurendas Rosetta kiirust 3,6 km\/s v\u00f5rra, suunates kosmoselaeva P\u00e4ikeses\u00fcsteemi \u00e4\u00e4realade poole. J\u00e4rgmine etapp selle 10-aastasel teekonnal on m\u00f6\u00f6dalend suure asteroidi Lutetia juurest 2010. aasta juulis. Seej\u00e4rel l\u00e4heb Rosetta talveunne, millest ta \u00e4rkab 2014. aasta kevadel.<\/p>","protected":false},"excerpt":{"rendered":"
