En af de l\u00e6ngste rummissioner nogensinde sluttede den 30. juni 2009, da den sidste kommando blev sendt til ESA\/NASA-rumfart\u00f8jet Ulysses. Ulysses blev opkaldt efter en legendarisk gr\u00e6sk helt, der overlevede utallige eventyr under en 20-\u00e5rig \u201codysse\u201d langt fra hjemmet. Rumfart\u00f8jet, der blev opsendt i oktober 1990, oplevede ogs\u00e5 mange eventyr undervejs og tilbragte n\u00e6sten lige s\u00e5 lang tid med at udforske det ukendte.<\/p>\n<\/div>\n

I l\u00f8bet af sine mere end 18 \u00e5r i rummet stod Ulysses bag mange gennembrud. Under en forbiflyvning af Jupiter i februar 1992 kastede den gigantiske planets kraftige tyngdekraft rumfart\u00f8jet ind i en unik bane, der f\u00f8rte det langt over og under planeternes baner. For f\u00f8rste gang kunne forskerne foretage detaljerede unders\u00f8gelser af Solens polare omr\u00e5der og deres sammenh\u00e6ng med den supersoniske solvind.<\/p>\n

Ulysses\u2019 mission skulle egentlig v\u00e6re afsluttet i 1995, men det lille, sejlivede rumfart\u00f8j fortsatte simpelthen med at flyve og gennemf\u00f8rte til sidst tre passager over Solens poler. To af disse fandt sted, da Solen var i et roligt hum\u00f8r, mens bes\u00f8get i 2000\u20132001 fandt sted, da Solen var p\u00e5 sit mest voldsomme.<\/p>\n

Desv\u00e6rre l\u00f8b atomkraftkilden p\u00e5 Ulysses gradvist t\u00f8r, indtil den uforf\u00e6rdede rumfart\u00f8j havde sv\u00e6rt ved at fungere. Det var forventet, at satellitten ville blive taget ud af drift i 2008, men operat\u00f8rerne form\u00e5ede at forhindre, at den fr\u00f8s fast, ved at udl\u00f8se en kort man\u00f8vre med raketmotorerne hver anden time. Ulysses bev\u00e6gede sig imidlertid l\u00e6ngere og l\u00e6ngere v\u00e6k fra Jorden, og i midten af 2009 bet\u00f8d den d\u00e5rlige kommunikation, at der kun blev modtaget meget f\u00e5 videnskabelige data. Det var p\u00e5 tide at sige farvel til rumpioneren.<\/p>","protected":false},"excerpt":{"rendered":"
