I marts 1986 fl\u00f8j ESA\u2019s rumfart\u00f8j Giotto helt ind til 600 km fra Halleys komets kerne. Det sendte de f\u00f8rste n\u00e6rbilleder af en komets iskold kerne tilbage. Nu er et andet ESA-rumfart\u00f8j ved navn Rosetta p\u00e5 vej mod en komet. Rosetta er den mest komplekse rummission, Europa nogensinde har gennemf\u00f8rt.<\/p>\n<\/div>\n

Rumfart\u00f8jet p\u00e5 3 ton medbringer 11 eksperimenter og en landingsfart\u00f8j, der rummer yderligere 9 eksperimenter. Det f\u00e5r sin str\u00f8m fra to enorme solpaneler, der hver er 14 meter lange.<\/p>\n

Rosetta, der blev opsendt den 2. marts 2004, vil bruge 10 \u00e5r p\u00e5 at n\u00e5 frem til kometen Churyumov-Gerasimenko. Den kringlede rute omfatter tre forbiflyvninger af Jorden og \u00e9n af Mars. Rosetta vil ogs\u00e5 dykke ind og ud af det prim\u00e6re asteroideb\u00e6lte mellem Mars og Jupiter. Dette giver den mulighed for at tage n\u00e6rbilleder af to asteroider, Steins og Lutetia.<\/p>\n

N\u00e5r Rosetta n\u00e6rmer sig kometen, vil den s\u00e6nke farten og \u00e6ndre sin bane, s\u00e5 den g\u00e5r i kredsl\u00f8b blot f\u00e5 kilometer over den faste kerne.<\/p>\n

N\u00e5r kometen er kortlagt, vil Rosetta udsende sin landingsfart\u00f8j (kaldet Philae). Dette vil forankre sig til kometkernen og sende de f\u00f8rste billeder tilbage fra en komets overflade.<\/p>\n

H\u00f8jt oppe i rummet vil rumfart\u00f8jet f\u00f8lge kometen, mens den suser mod det indre solsystem. Under denne 18 m\u00e5neder lange forf\u00f8lgelse vil kometens frosne is omdannes til gas, hvilket vil sende str\u00e5ler af materiale ud i rummet. Rosetta vil for f\u00f8rste gang vise os de dramatiske forandringer, der finder sted, n\u00e5r dette isbjerg i rummet opvarmes af Solen.<\/p>","protected":false},"excerpt":{"rendered":"
