Efter en resa p\u00e5 10 l\u00e5nga \u00e5r, under vilken den har tillryggalagt mer \u00e4n h\u00e4lften av solsystemets l\u00e4ngd och kretsat runt solen fem g\u00e5nger, har rymdfarkosten Rosetta \u00e4ntligen n\u00e5tt sitt m\u00e5l: kometen 67P\/Churyumov\u2013Gerasimenko!<\/p>\n<\/div>\n

Rosetta kretsar f\u00f6r n\u00e4rvarande 100 km ovanf\u00f6r kometens yta och skickar information om sin nya v\u00e4n tillbaka till jorden. Under de n\u00e4rmaste veckorna \u00e4r Rosettas huvuduppgift att leta efter den perfekta landningsplatsen f\u00f6r den sond den har med sig, som heter Philae (uttalas FEE-lay).<\/p>\n

Om allt g\u00e5r som det ska kommer Philae om bara n\u00e5gra m\u00e5nader att bli den f\u00f6rsta rymdsonden n\u00e5gonsin som sl\u00e4pps ner p\u00e5 en komets yta!<\/p>\n

Men Rosettas resa slutar inte d\u00e4r; under m\u00e5nga m\u00e5nader kommer den lilla rymdsonden att f\u00f6lja med kometen n\u00e4r den kretsar runt Solen och sedan \u00e5terv\u00e4nder mot Jupiter igen.<\/p>\n

Om ett \u00e5r kommer de b\u00e5da att n\u00e5 den punkt som ligger n\u00e4rmast Solen under sin resa genom solsystemet \u2013 det \u00e4r d\u00e4r kometen verkligen kommer att b\u00f6rja lysa.<\/p>\n

Kometer \u00e4r klumpar av kosmisk is och sten, vilket inneb\u00e4r att kometen 67P kommer att b\u00f6rja sm\u00e4lta n\u00e4r den n\u00e4rmar sig solen. Den f\u00f6r\u00e5ngade isen fr\u00e5n kometen kommer att bilda en magnifik svans, liknande de som vi ibland har turen att se glida \u00f6ver himlen.<\/p>\n

Tyv\u00e4rr kommer kometen 67P inte att synas p\u00e5 v\u00e5r natthimmel utan kraftfulla teleskop, trots sin bl\u00e4ndande svans. Ist\u00e4llet kommer Rosetta att ge oss n\u00e5got \u00e4nnu b\u00e4ttre \u2013 en n\u00e4rbild av hur kometen f\u00f6r\u00e4ndras i solens bl\u00e4ndande sken!<\/p>\n

Rolig fakta<\/h2>\n

Uppdraget har f\u00e5tt sitt namn efter Rosettastenen, en forntida stentavla som gjorde det m\u00f6jligt f\u00f6r oss att tyda de forntida egyptiska hieroglyferna. Precis som Rosettastenen kommer ESA:s Rosetta-uppdrag att f\u00f6r\u00e4ndra v\u00e5r f\u00f6rst\u00e5else av det f\u00f6rflutna genom att avsl\u00f6ja mysterierna kring objekt som best\u00e5r av rester fr\u00e5n solsystemets bildande: kometer.<\/p>","protected":false},"excerpt":{"rendered":"
