Kig mod vest efter en skyfri solnedgang i de kommende m\u00e5neder, og du vil helt sikkert se en str\u00e5lende \u201caftenstjerne\u00ab. Men dette bl\u00e6ndende syn er ingen stjerne. Det er planeten Venus, som er m\u00e5let for Europas seneste mission ud i det ydre rum.<\/p>\n<\/div>\n

Venus Express bliver det f\u00f8rste ESA-rumfart\u00f8j, der skal udforske Jordens n\u00e6sten identiske tvilling. Det skal efter planen opsendes ombord p\u00e5 en russisk Sojuz-raket i oktober 2005 og forventes at g\u00e5 i kredsl\u00f8b om Venus i april 2006.<\/p>\n

Rumfart\u00f8jet, der vil flyve i en h\u00f8jde mellem 250 og 66.000 km over polerne, vil bruge to venus\u00e5r (500 jorddage) p\u00e5 at unders\u00f8ge det t\u00e6tte skyd\u00e6kke og atmosf\u00e6ren p\u00e5 Jordens n\u00e6rmeste naboplanet.<\/p>\n

Der er sendt mere end 20 russiske og amerikanske rumfart\u00f8jer ud for at udforske den anden planet fra Solen, men der er stadig mange ubesvarede sp\u00f8rgsm\u00e5l:<\/p>\n

    Hvad er temperaturen og sammens\u00e6tningen af atmosf\u00e6ren?<\/p>\n<\/li>\n

    Hvordan cirkulerer atmosf\u00e6ren?<\/p>\n<\/li>\n

    Syv videnskabelige instrumenter om bord p\u00e5 Venus Express skal fors\u00f8ge at l\u00f8se disse g\u00e5der.<\/p>\n

    Som navnet antyder, blev Venus Express udviklet og bygget p\u00e5 blot tre \u00e5r \u2013 hvilket er meget hurtigt for et planetarisk rumfart\u00f8j. Ligesom ESA\u2019s succesrige Mars Express-orbiter er rumfart\u00f8jet blevet tilpasset til de h\u00f8jere temperaturer og str\u00e5lingsniveauer p\u00e5 Venus. De fleste af dets instrumenter er baseret p\u00e5 hardware, der er udviklet til Mars Express- og Rosetta-missionerne.<\/p>","protected":false},"excerpt":{"rendered":"
