Touchdown! For f\u00f8rste gang i menneskehedens historie har vi landet et rumfart\u00f8j p\u00e5 overfladen af en komet.<\/p>\n<\/div>\n

Efter en 10-\u00e5rig rejse n\u00e5ede Rosetta og Philae endelig frem til deres destination, kometen 67P\/Churyumov-Gerasimenko, i august. Siden da har Rosetta bev\u00e6get sig t\u00e6ttere og t\u00e6ttere p\u00e5 kometen for at forberede sig p\u00e5 missionens n\u00e6ste udfordring \u2013 at sende Philae ned p\u00e5 overfladen.<\/p>\n

Jo t\u00e6ttere Rosetta kom p\u00e5 denne m\u00e6rkelige verden, jo mere fantastisk blev den. Vi opdagede, at den er fyldt med kratere, t\u00e5rnh\u00f8je klipper og kampesten p\u00e5 st\u00f8rrelse med huse. Der str\u00f8mmer endda str\u00e5ler af gas og st\u00f8v ud fra overfladen.<\/p>\n

Efter at have unders\u00f8gt planetens overflade i mange uger valgte eksperterne til sidst det bedste sted, hvor Philae kunne lande. Da denne beslutning var truffet, var den n\u00e6ste opgave at v\u00e6lge den bedste bane omkring kometen, s\u00e5 Philae kunne lande p\u00e5 det rette sted.<\/p>\n

Endelig var det tid for Philae at tage afsked med Rosetta og g\u00f8re sig klar til den hidtil st\u00f8rste udfordring. Tidligt i g\u00e5r morges p\u00e5begyndte Philae den lange nedstigning mod kometen. I syv nervepirrende timer sad vi og ventede hj\u00e6lpel\u00f8st, mens Philae drev gennem rummet \u2013 uden mulighed for at styre den, hvis den kom ud af kurs.<\/p>\n

Endelig, med et dybt suk af lettelse og en runde applaus, modtog vi besked fra Philae om, at den var ankommet sikkert, og at denne ekstraordin\u00e6re bedrift var lykkedes!<\/p>\n

Allerede nu er Philae begyndt at indsamle s\u00e5 mange oplysninger som muligt om denne fascinerende miniatureverden. Sammen med Rosetta, der kredser t\u00e6t omkring kometen, vil den lille sonde hj\u00e6lpe os med at forst\u00e5 et af de \u00e6ldste objekter i vores solsystem.<\/p>\n

Sjovt faktum:<\/b> Kometen Churyumov-Gerasimenko\/67P suser i \u00f8jeblikket mod Solen med en hastighed p\u00e5 60.000 km i timen \u2013 det er mere end dobbelt s\u00e5 hurtigt som rumf\u00e6rgen!<\/p><\/p>","protected":false},"excerpt":{"rendered":"
