En gammel ven vendte hjem p\u00e5 et kort bes\u00f8g den 13. november. 44 m\u00e5neder efter opsendelsen fra Kourou i Fransk Guyana fl\u00f8j ESA\u2019s rumfart\u00f8j Rosetta forbi Jorden for anden gang. Europas kometj\u00e6ger har nu tilbagelagt lidt over 3 milliarder km, men den har stadig 4 milliarder km tilbage, f\u00f8r den ankommer til sin destination, kometen 67\/P Churyumov-Gerasimenko, i 2014.<\/p>\n<\/div>\n

Rosetta suser rundt i det indre solsystem som en billardkugle, mens den tager fart og \u00e6ndrer bane under sine t\u00e6tte m\u00f8der med Jorden og Mars. Denne seneste milep\u00e6l p\u00e5 den episke rejse var den tredje af de fire planlagte planet\u00e6re svingman\u00f8vrer for Rosetta.<\/p>\n

Efter at dens bane var blevet finjusteret ved en 42 sekunders aktivering af raketmotorerne den 18. oktober, var Rosetta pr\u00e6cis p\u00e5 kurs mod forbiflyvningen af Jorden. Kl. 21:57 CET susede det 3 ton tunge rumfart\u00f8j forbi planeten med en hastighed p\u00e5 45.000 km\/t (12,5 km\/s). Da den fl\u00f8j hen over Stillehavet sydvest for Chile, befandt Rosetta sig kun 5.295 km over jordoverfladen.<\/p>\n

I forbindelse med det n\u00e6rmeste m\u00f8de med Jorden tog Rosetta et grundigt kig p\u00e5 Jorden, hvor den foretog observationer af Jordens atmosf\u00e6re og magnetosf\u00e6re, tog billeder af byomr\u00e5der og ledte efter meteorer fra rummet. Derefter p\u00e5begyndte den en r\u00e6kke observationer af Jorden-M\u00e5ne-systemet p\u00e5 sin udg\u00e5ende bane.<\/p>\n

Rumfart\u00f8jet vil nu blive katapulteret ud mod det ydre solsystem, inden det vender tilbage til Jorden for sidste gang i november 2009. Men inden da, n\u00e5r det passerer asteroideb\u00e6ltet, vil Rosetta benytte lejligheden til at unders\u00f8ge asteroiden Steins p\u00e5 t\u00e6t hold i september 2008.<\/p>","protected":false},"excerpt":{"rendered":"
