En gammel venn kom hjem p\u00e5 et kort bes\u00f8k den 13. november. 44 m\u00e5neder etter oppskytingen fra Kourou i Fransk Guyana suste ESAs romfart\u00f8y Rosetta forbi Jorden for andre gang. Europas kometjeger har n\u00e5 tilbakelagt litt over 3 milliarder km, men har fortsatt 4 milliarder km igjen \u00e5 reise f\u00f8r den ankommer m\u00e5let sitt, kometen 67\/P Churyumov-Gerasimenko, i 2014.<\/p>\n<\/div>\n

Rosetta spretter rundt i det indre solsystemet som en biljardkule, mens den \u00f8ker farten og endrer bane under n\u00e6re m\u00f8ter med Jorden og Mars. Denne siste milep\u00e6len p\u00e5 den episke reisen var den tredje av fire planlagte svingninger rundt planeter for Rosetta.<\/p>\n

Etter at banen ble finjustert ved hjelp av en 42 sekunders aktivering av man\u00f8vreringsmotorene den 18. oktober, var Rosetta n\u00f8yaktig p\u00e5 kurs mot forbiflyvningen av Jorden. Kl. 21.57 CET suste det 3 tonn tunge romfart\u00f8yet forbi planeten med en hastighet p\u00e5 45 000 km\/t (12,5 km\/s). Da den sveipet over Stillehavet, s\u00f8rvest for Chile, befant Rosetta seg bare 5 295 km over bakken.<\/p>\n

Rundt det n\u00e6rmeste punktet p\u00e5 banen tok Rosetta en grundig titt p\u00e5 Jorden, gjennomf\u00f8rte observasjoner av atmosf\u00e6ren og magnetosf\u00e6ren, tok bilder av byomr\u00e5der og lette etter meteorer fra verdensrommet. Deretter innledet den en serie observasjoner av Jord-M\u00e5ne-systemet p\u00e5 sin tilbakevei.<\/p>\n

Romfart\u00f8yet vil n\u00e5 bli skutt ut mot det ytre solsystemet f\u00f8r det kommer tilbake til Jorden for siste gang i november 2009. Men f\u00f8r det, n\u00e5r det passerer gjennom asteroidebeltet, vil Rosetta benytte anledningen til \u00e5 studere asteroiden Steins p\u00e5 n\u00e6rt hold i september 2008.<\/p>","protected":false},"excerpt":{"rendered":"
