Sp\u00e6ndingen stiger over hele verden, mens uret t\u00e6ller ned til opsendelsen af to nye, kraftfulde ESA-rumobservatorier \u2013 Herschel og Planck. Rumfart\u00f8jerne vil blive opsendt sammen fra ESAs rumhavn i Kourou i Fransk Guyana kl. 15:12 CEST den 14. maj. Fastgjort \u00f8verst p\u00e5 den gigantiske Ariane 5-raket vil de to rumfart\u00f8jer v\u00e6re ca. 11 m h\u00f8je og 4,5 m brede med en samlet v\u00e6gt p\u00e5 5,7 tons.<\/p>\n<\/div>\n

Cirka 2,5 minutter efter opsendelsen vil Ariane 5\u2019s fastbr\u00e6ndstofsraketter blive kastet af. Satellitternes beskyttende kappe kastes af cirka 50 sekunder senere. Derefter adskilles det \u00f8verste trin, og dets motor t\u00e6ndes ca. 9 minutter inde i flyvningen. N\u00e5r satellitterne skal frigives, vil trinnet bev\u00e6ge sig v\u00e6k fra Jorden med en hastighed p\u00e5 ca. 10 km\/s. Herschel vil blive frigivet f\u00f8rst, ca. 26 minutter efter opsendelsen. Planck f\u00f8lger ca. 2\u00bd minut senere.<\/p>\n

I missionens indledende fase vil missionskontroll\u00f8rerne overv\u00e5ge satellitterne 22 timer i d\u00f8gnet fra ESA\u2019s jordstationer i Australien, Spanien og Sydamerika. Begge satellitter vil selv finde vej til L2, et s\u00e6rligt punkt i rummet, der ligger 1,5 millioner km v\u00e6k p\u00e5 Jordens natside. L2 er et fremragende sted, da det giver dem mulighed for at observere himlen uden problemer med sollys og samtidig bruge meget lidt br\u00e6ndstof. Planck forventes at begynde at sende data tilbage i juli, efterfulgt af Herschel i september.<\/p>\n
