Den 4 juli kommer en 370 kg tung kopparsond fr\u00e5n NASA:s rymdfarkost Deep Impact att krascha in i kometen Tempel 1:s isiga k\u00e4rna och skapa en enorm krater. Teleskop \u00f6ver hela v\u00e4rlden och rymdfarkoster som NASA-ESA:s rymdteleskop Hubble kommer att f\u00f6lja h\u00e4ndelsen noga f\u00f6r att se vad som h\u00e4nder n\u00e4r den explosiva kollisionen intr\u00e4ffar. Bland dem som deltar i ett av v\u00e4rldens st\u00f6rsta astronomiska observationsprogram finns ESA:s kometj\u00e4gare Rosetta.<\/p>\n<\/div>\n

Rosetta har ytterligare nio \u00e5r kvar innan den n\u00e5r sitt m\u00e5l, kometen Churyumov-Gerasimenko. Mellan den 29 juni och den 14 juli kommer rymdfarkosten dock att ha en f\u00f6rstklassig plats f\u00f6r att observera en annan av solsystemets isiga byggstenar. Rosetta kommer att f\u00e4rdas genom rymden p\u00e5 ett avst\u00e5nd av cirka 80 miljoner km fr\u00e5n kometen och anv\u00e4nda sina k\u00e4nsliga instrument f\u00f6r att studera den dramatiska kollisionen med Tempel 1.<\/p>\n

Innan nedslaget kommer Rosetta att observera den m\u00f6rka, isiga k\u00e4rnan under tre fullst\u00e4ndiga rotationer. Detta kommer att ge forskarna m\u00f6jlighet att f\u00e5 kunskap om kometens tillst\u00e5nd innan kollisionen \u00e4ger rum.<\/p>\n

Under och efter nedslaget kommer Rosettas kamera att ta bilder p\u00e5 l\u00e5ngt avst\u00e5nd av k\u00e4rnan och det moln av gas och stoft som slungas ut i rymden. Andra instrument kommer att unders\u00f6ka molnets temperatur och f\u00f6rs\u00f6ka ta reda p\u00e5 vad det best\u00e5r av.<\/p>\n

Tempel 1 \u00e4r en kortperiodisk komet som r\u00f6r sig mellan Mars och Jupiters banor. Forskarna vill l\u00e4ra sig mer om s\u00e5dana ur\u00e5ldriga objekt, eftersom de \u00e4r rester fr\u00e5n planeternas bildande f\u00f6r 4,5 miljarder \u00e5r sedan.<\/p>","protected":false},"excerpt":{"rendered":"
