Cassini-Huygens-missionen, som ESA, NASA og det italienske rumagentur deltog i, har \u00e6ndret mange af vores forestillinger om Saturn-systemet. Den blev opsendt fra Florida i oktober 1997, og det tog n\u00e6sten syv \u00e5r at n\u00e5 frem til Saturn, hvor den tilbagelagde n\u00e6sten 3,5 milliarder kilometer. Rumfart\u00f8jet p\u00e5 5,6 ton bestod af to dele \u2013 Cassini-orbiteren og Huygens-sonden.<\/p>\n<\/div>\n

Cassini er det f\u00f8rste rumfart\u00f8j, der kredser om Saturn. Det har 12 eksperimenter om bord. Siden ankomsten til Saturn den 1. juli 2004 har Cassini sendt enorme m\u00e6ngder nye oplysninger tilbage om Saturn, dens ringe, m\u00e5ner og magnetfelt.<\/p>\n

Cassini-Huygens-missionen, der oprindeligt var planlagt til at vare fire \u00e5r, har v\u00e6ret s\u00e5 succesfuld, at den er blevet forl\u00e6nget indtil mindst 2017. Den har fl\u00f8jet forbi syv af de st\u00f8rre m\u00e5ner, herunder den gigantiske Titan \u2013 som er st\u00f8rre end planeten Merkur. Rumfart\u00f8jet har passeret Titan mere end 70 gange. Med en afstand p\u00e5 under 880 km til m\u00e5nen har det unders\u00f8gt Titans orange skyer og den kv\u00e6lstofrige atmosf\u00e6re. Det har ogs\u00e5 kortlagt overfladen med et billedradarsystem. .<\/p>\n

Juledag 2004 adskilte Huygens sig fra Cassini. Tre uger senere styrtede den ned i Titans t\u00e6tte atmosf\u00e6re og blev dermed den f\u00f8rste sonde, der landede p\u00e5 overfladen af en planetm\u00e5ne (bortset fra vores egen M\u00e5ne). Beskyttet af et varmeskjold bremsede sonden ned fra 18.000 til 1.400 km i timen p\u00e5 blot tre minutter. Kort efter \u00e5bnede en stor faldsk\u00e6rm sig. I en h\u00f8jde p\u00e5 omkring 160 km begyndte sonden at tage billeder og unders\u00f8ge atmosf\u00e6ren. I mere end to timer blev data fra Huygens modtaget og gemt p\u00e5 Cassini, mens den fl\u00f8j forbi.<\/p>\n

Billederne og de \u00f8vrige oplysninger, som de seks instrumenter sendte tilbage, gav os for f\u00f8rste gang et indblik i, hvordan denne orange m\u00e5ne egentlig ser ud. Huygens landede p\u00e5 et t\u00f8rt flodleje, der var d\u00e6kket af sm\u00e5 isklumper.<\/p>","protected":false},"excerpt":{"rendered":"
