Den 4. juli vil en 370 kg tung kobbersonde fra NASAs romfart\u00f8y Deep Impact krasje inn i det iskalde hjertet av kometen Tempel 1 og skape et enormt krater. Teleskoper over hele verden og romfart\u00f8y som NASA-ESA-teleskopet Hubble vil f\u00f8lge n\u00f8ye med for \u00e5 se hva som skjer n\u00e5r det eksplosive sammenst\u00f8tet finner sted. Blant deltakerne i et av verdens st\u00f8rste astronomiske observasjonsprogrammer vil v\u00e6re ESAs kometjeger Rosetta.<\/p>\n<\/div>\n

Rosetta har fortsatt ni \u00e5r igjen f\u00f8r den n\u00e5r m\u00e5let sitt, kometen Churyumov-Gerasimenko. Imidlertid vil romfart\u00f8yet ha en f\u00f8rsteklasses plass til \u00e5 observere en annen av solsystemets isete byggesteiner mellom 29. juni og 14. juli. Mens den suser gjennom rommet i en avstand p\u00e5 rundt 80 millioner km fra kometen, vil Rosetta bruke sine f\u00f8lsomme instrumenter til \u00e5 studere den dramatiske kollisjonen med Tempel 1.<\/p>\n

F\u00f8r sammenst\u00f8tet skal Rosetta observere den m\u00f8rke, isbelagte kjernen gjennom tre hele rotasjoner. Dette vil gi forskerne mulighet til \u00e5 f\u00e5 innsikt i kometens tilstand f\u00f8r kollisjonen finner sted.<\/p>\n

Under og etter sammenst\u00f8tet vil Rosettas kamera ta bilder p\u00e5 lang avstand av kjernen og skyen av gass og st\u00f8v som blir sprengt ut i rommet. Andre instrumenter skal m\u00e5le temperaturen i skyen og fors\u00f8ke \u00e5 finne ut hva den best\u00e5r av.<\/p>\n

Tempel 1 er en kortperiodisk komet som beveger seg mellom Mars\u2019 og Jupiters baner. Forskere \u00f8nsker \u00e5 l\u00e6re mer om slike eldgamle himmellegemer, siden de er rester fra planetdannelsen for 4,5 milliarder \u00e5r siden.<\/p>","protected":false},"excerpt":{"rendered":"
