En gammal v\u00e4n \u00e5terv\u00e4nde hem f\u00f6r ett kort bes\u00f6k den 13 november. 44 m\u00e5nader efter uppskjutningen fr\u00e5n Kourou i Franska Guyana passerade ESA:s rymdsond Rosetta f\u00f6rbi jorden f\u00f6r andra g\u00e5ngen. Europas kometj\u00e4gare har nu flugit drygt 3 miljarder km, men har fortfarande ytterligare 4 miljarder km kvar att f\u00e4rdas innan den anl\u00e4nder till sitt m\u00e5l, kometen 67\/P Churyumov-Gerasimenko, \u00e5r 2014.<\/p>\n<\/div>\n

Rosetta studsar runt i det inre solsystemet som en biljardboll, samtidigt som den \u00f6kar farten och \u00e4ndrar sin bana vid n\u00e4ra m\u00f6ten med Jorden och Mars. Denna senaste milstolpe p\u00e5 den episka resan utgjorde den tredje av fyra planerade sv\u00e4ngar runt planeter f\u00f6r Rosetta.<\/p>\n

Efter att dess omloppsbana finjusterats genom en 42 sekunder l\u00e5ng aktivering av styrraketerna den 18 oktober befann sig Rosetta precis p\u00e5 r\u00e4tt kurs f\u00f6r f\u00f6rbiflygningen av jorden. Kl. 21.57 CET susade den 3 ton tunga rymdfarkosten f\u00f6rbi planeten med en hastighet p\u00e5 45 000 km\/h (12,5 km\/s). N\u00e4r den svepte \u00f6ver Stilla havet, sydv\u00e4st om Chile, befann sig Rosetta endast 5 295 km \u00f6ver marken.<\/p>\n

N\u00e4r Rosetta befann sig som n\u00e4rmast Jorden tittade den noga p\u00e5 planeten, gjorde observationer av dess atmosf\u00e4r och magnetosf\u00e4r, fotograferade stadsomr\u00e5den och letade efter meteorer fr\u00e5n rymden. D\u00e4refter inledde den en serie observationer av jord-m\u00e5ne-systemet p\u00e5 sin v\u00e4g bort fr\u00e5n Jorden.<\/p>\n

Rymdfarkosten kommer nu att skjutas ut mot det yttre solsystemet innan den \u00e5terv\u00e4nder till jorden f\u00f6r sista g\u00e5ngen i november 2009. Men innan dess, n\u00e4r den passerar asteroidb\u00e4ltet, kommer Rosetta att passa p\u00e5 att studera asteroiden Steins p\u00e5 n\u00e4ra h\u00e5ll i september 2008.<\/p>","protected":false},"excerpt":{"rendered":"
