I mars 1986 fl\u00f6g ESA:s rymdsond Giotto fram till inom 600 km fr\u00e5n Halleys kometk\u00e4rna. Den s\u00e4nde tillbaka de f\u00f6rsta n\u00e4rbilderna av en komets isiga k\u00e4rna. Nu \u00e4r en annan av ESA:s rymdsonder, Rosetta, p\u00e5 v\u00e4g mot en komet. Rosetta \u00e4r den mest komplexa rymduppdraget som Europa n\u00e5gonsin genomf\u00f6rt.<\/p>\n<\/div>\n

Rymdfarkosten, som v\u00e4ger 3 ton, har 11 experiment ombord samt en landare med ytterligare 9 experiment. Den f\u00e5r sin energi fr\u00e5n tv\u00e5 enorma solpaneler, som var och en \u00e4r 14 meter l\u00e5nga.<\/p>\n

Rosetta, som sk\u00f6ts upp den 2 mars 2004, kommer att ta tio \u00e5r p\u00e5 sig att n\u00e5 kometen Churyumov-Gerasimenko. Den omv\u00e4garna omfattar tre f\u00f6rbiflygningar av Jorden och en av Mars. Rosetta passerar ocks\u00e5 in och ut ur det huvudsakliga asteroidb\u00e4ltet mellan Mars och Jupiter. Detta g\u00f6r det m\u00f6jligt f\u00f6r den att ta n\u00e4rbilder av tv\u00e5 asteroider, Steins och Lutetia.<\/p>\n

N\u00e4r Rosetta n\u00e4rmar sig kometen kommer den att sakta in och \u00e4ndra sin bana s\u00e5 att den g\u00e5r in i en omloppsbana endast n\u00e5gra kilometer ovanf\u00f6r den fasta k\u00e4rnan.<\/p>\n

N\u00e4r kometen v\u00e4l har kartlagts kommer Rosetta att sl\u00e4ppa sin landare (som heter Philae). Den kommer att f\u00f6rankra sig p\u00e5 kometk\u00e4rnan och skicka tillbaka de f\u00f6rsta bilderna fr\u00e5n en komets yta.<\/p>\n

H\u00f6gt uppe i rymden kommer rymdsonden att f\u00f6lja kometen n\u00e4r den rusar mot det inre solsystemet. Under denna 18 m\u00e5nader l\u00e5nga jakt kommer kometens frusna is att f\u00f6rvandlas till gas, vilket leder till att str\u00e5lar av material skjuts ut i rymden. Rosetta kommer f\u00f6r f\u00f6rsta g\u00e5ngen att visa oss de dramatiska f\u00f6r\u00e4ndringar som sker n\u00e4r detta isberg i rymden v\u00e4rms upp av solen.<\/p>","protected":false},"excerpt":{"rendered":"
