Cassini-Huygens-uppdraget, d\u00e4r ESA, NASA och den italienska rymdorganisationen deltog, har f\u00f6r\u00e4ndrat m\u00e5nga av v\u00e5ra uppfattningar om Saturnussystemet. Uppskjutningen \u00e4gde rum fr\u00e5n Florida i oktober 1997, och det tog n\u00e4stan sju \u00e5r att n\u00e5 Saturnus, en resa p\u00e5 n\u00e4stan 3,5 miljarder kilometer. Rymdfarkosten, som v\u00e4gde 5,6 ton, bestod av tv\u00e5 delar \u2013 rymdsonden Cassini och sonden Huygens.<\/p>\n<\/div>\n

Cassini \u00e4r den f\u00f6rsta rymdsonden som kretsar kring Saturnus. Den \u00e4r utrustad med 12 experiment. Sedan den anl\u00e4nde till Saturnus den 1 juli 2004 har Cassini skickat tillbaka enorma m\u00e4ngder ny information om Saturnus, dess ringar, m\u00e5nar och magnetf\u00e4lt.<\/p>\n

Cassini-Huygens, som ursprungligen planerades som ett fyra\u00e5rigt uppdrag, har varit s\u00e5 framg\u00e5ngsrikt att det har f\u00f6rl\u00e4ngts till \u00e5tminstone 2017. Den har flugit f\u00f6rbi sju av de st\u00f6rre m\u00e5narna, d\u00e4ribland j\u00e4tten Titan \u2013 som \u00e4r st\u00f6rre \u00e4n planeten Merkurius. Rymdsonden har flugit f\u00f6rbi Titan mer \u00e4n 70 g\u00e5nger. Genom att flyga inom 880 km fr\u00e5n m\u00e5nen har den studerat Titans orangef\u00e4rgade moln och kv\u00e4verika atmosf\u00e4r. Den har ocks\u00e5 kartlagt dess yta med hj\u00e4lp av en bildradar.<\/p>\n

P\u00e5 juldagen 2004 separerade Huygens fr\u00e5n Cassini. Tre veckor senare st\u00f6rtade den in i Titans t\u00e4ta atmosf\u00e4r och blev d\u00e4rmed den f\u00f6rsta sonden som landade p\u00e5 ytan av en planetm\u00e5n (f\u00f6rutom v\u00e5r egen m\u00e5ne). Skyddad av ett v\u00e4rmeskydd saktade sonden in fr\u00e5n 18 000 till 1 400 km per timme p\u00e5 bara tre minuter. Strax d\u00e4refter \u00f6ppnade sig en stor fallsk\u00e4rm. P\u00e5 en h\u00f6jd av cirka 160 km b\u00f6rjade sonden ta bilder och unders\u00f6ka atmosf\u00e4ren. Under mer \u00e4n tv\u00e5 timmar mottogs data fr\u00e5n Huygens och lagrades p\u00e5 Cassini medan den fl\u00f6g \u00f6ver sonden.<\/p>\n

Bilderna och den \u00f6vriga informationen som s\u00e4ndes tillbaka fr\u00e5n dess sex instrument gav oss f\u00f6r f\u00f6rsta g\u00e5ngen en bild av hur denna orangef\u00e4rgade m\u00e5ne egentligen ser ut. Huygens landade p\u00e5 en torr flodb\u00e4dd t\u00e4ckt av sm\u00e5 isiga stenblock.<\/p>","protected":false},"excerpt":{"rendered":"
