En av de lengste romferdene noensinne ble avsluttet 30. juni 2009, da den siste kommandoen ble sendt til ESA\/NASA-romfart\u00f8yet Ulysses. Ulysses ble oppkalt etter en legendarisk gresk helt som overlevde utallige eventyr under en 20 \u00e5r lang \u201codyss\u00e9\u201d langt fra hjemmet. Romfart\u00f8yet, som ble skutt opp i oktober 1990, opplevde ogs\u00e5 mange eventyr underveis og brukte nesten like lang tid p\u00e5 \u00e5 utforske det ukjente.<\/p>\n<\/div>\n

I l\u00f8pet av mer enn 18 \u00e5r i rommet oppn\u00e5dde Ulysses mange gjennombrudd. Under en forbiflyging av Jupiter i februar 1992 kastet den gigantiske planetens kraftige tyngdekraft romfart\u00f8yet inn i en unik bane som f\u00f8rte det langt over og under planetenes baner. For f\u00f8rste gang kunne forskerne foreta detaljerte studier av solens polomr\u00e5der og deres sammenheng med den supersoniske solvinden.<\/p>\n

Ulysses\u2019 oppdrag var forventet \u00e5 avsluttes i 1995, men det seige lille romfart\u00f8yet fortsatte bare \u00e5 kj\u00f8re p\u00e5 og fullf\u00f8rte til slutt tre passeringer over solens poler. To av disse fant sted mens solen var i et rolig hum\u00f8r, mens bes\u00f8ket i 2000\u20132001 fant sted da solen var p\u00e5 sitt mest voldsomme.<\/p>\n

Dessverre gikk atomkraftkilden p\u00e5 Ulysses gradvis tom, til den uredde romfareren til slutt slet med \u00e5 holde driften i gang. Det var forventet at satellitten skulle stenges ned i 2008, men operat\u00f8rene klarte \u00e5 forhindre at den fr\u00f8s fast ved \u00e5 utf\u00f8re en kort man\u00f8ver med thrusterne hver annen time. Ulysses beveget seg imidlertid stadig lenger bort fra Jorden, og ved midten av 2009 f\u00f8rte d\u00e5rlig kommunikasjon til at sv\u00e6rt f\u00e5 vitenskapelige data ble sendt tilbake. Det var p\u00e5 tide \u00e5 ta farvel med rompioneren.<\/p>","protected":false},"excerpt":{"rendered":"
