Efter en rejse p\u00e5 10 lange \u00e5r, hvor den har tilbagelagt over halvdelen af solsystemets l\u00e6ngde og kredset fem gange om Solen, er rumfart\u00f8jet Rosetta endelig n\u00e5et frem til sin destination: kometen 67P\/Churyumov\u2013Gerasimenko!<\/p>\n<\/div>\n

Rosetta kredser i \u00f8jeblikket 100 km over kometens overflade og sender oplysninger om sin nye ven tilbage til Jorden. I de kommende uger er Rosettas vigtigste opgave at finde det perfekte landingssted til den sonde, den har med ombord, som hedder Philae (udtales FEE-lay).<\/p>\n

Hvis alt g\u00e5r efter planen, vil Philae om blot et par m\u00e5neder blive den f\u00f8rste rumsonde nogensinde, der s\u00e6nkes ned p\u00e5 en komets overflade!<\/p>\n

Men Rosettas rejse slutter ikke der; i mange m\u00e5neder vil det lille rumfart\u00f8j f\u00f8lge med kometen, mens den kredser om Solen og derefter vender tilbage mod Jupiter igen.<\/p>\n

Om et \u00e5r vil de to n\u00e5 det punkt, hvor de er t\u00e6ttest p\u00e5 Solen p\u00e5 deres rejse gennem solsystemet \u2014 det er her, kometen for alvor vil begynde at str\u00e5le.<\/p>\n

Kometer er klumper af kosmisk is og sten, hvilket betyder, at kometen 67P vil begynde at smelte, efterh\u00e5nden som den n\u00e6rmer sig Solen. Den fordampede is fra kometen vil danne en storsl\u00e5et hale, ligesom dem, vi nogle gange er s\u00e5 heldige at se glide hen over vores himmel.<\/p>\n

Desv\u00e6rre vil kometen 67P ikke kunne ses p\u00e5 vores nattehimmel uden kraftige teleskoper, selv ikke med sin str\u00e5lende hale. Til geng\u00e6ld vil Rosetta give os noget endnu bedre \u2014 et n\u00e6rbillede af, hvordan kometen forandrer sig i solens skarpe lys!<\/p>\n

Sjovt faktum<\/h2>\n

Missionen er opkaldt efter Rosettastenen, en gammel stentavle, der gjorde det muligt for os at tyde de gamle egyptiske hieroglyffer. Ligesom Rosettastenen vil ESA\u2019s Rosetta-mission \u00e6ndre vores forst\u00e5else af fortiden ved at afsl\u00f8re mysterierne bag objekter, der er dannet af resterne fra vores solsystems dannelse: kometer.<\/p>","protected":false},"excerpt":{"rendered":"
