Hvis du ser mot vest etter en skyfri solnedgang i l\u00f8pet av de kommende m\u00e5nedene, vil du ikke kunne unng\u00e5 \u00e5 se en str\u00e5lende \u201caftenstjerne\u00bb. Men dette blendende synet er ingen stjerne. Det er planeten Venus, m\u00e5let for Europas nyeste romferd til det ytre rom.<\/p>\n<\/div>\n

Venus Express blir det f\u00f8rste romfart\u00f8yet fra ESA som skal utforske Jordens n\u00e6rmeste tvilling. Oppskytingen er planlagt om bord p\u00e5 en russisk Sojuz-rakett i oktober 2005, og romfart\u00f8yet forventes \u00e5 g\u00e5 inn i bane rundt Venus i april 2006.<\/p>\n

Romfart\u00f8yet skal fly mellom 250 og 66 000 km over polene og bruke to venus\u00e5r (500 jorddager) p\u00e5 \u00e5 unders\u00f8ke det tette skydekket og atmosf\u00e6ren til Jordens n\u00e6rmeste naboplanet.<\/p>\n

Mer enn 20 russiske og amerikanske romfart\u00f8yer har blitt sendt ut for \u00e5 utforske den andre planeten fra Solen, men det gjenst\u00e5r fortsatt mange mysterier:<\/p>\n

    \n
  • \n

    Hva er temperaturen og sammensetningen i atmosf\u00e6ren?<\/p>\n<\/li>\n

  • \n

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

  • \n

    Hvordan endrer sammensetningen seg fra toppen og ned?<\/p>\n<\/li>\n

  • \n

    Hvordan p\u00e5virker atmosf\u00e6ren overflaten?<\/p>\n<\/li>\n

  • \n

    Hvordan samvirker den \u00f8vre atmosf\u00e6ren med solvinden?<\/p>\n<\/li>\n<\/ul>\n

    Syv vitenskapelige instrumenter om bord p\u00e5 Venus Express skal fors\u00f8ke \u00e5 l\u00f8se disse g\u00e5tene.<\/p>\n

    Som navnet tilsier, ble Venus Express utviklet og bygget p\u00e5 bare tre \u00e5r \u2013 noe som er sv\u00e6rt raskt for et planetarisk romfart\u00f8y. I likhet med ESAs vellykkede Mars Express-orbiter er romfart\u00f8yet tilpasset for \u00e5 t\u00e5le de h\u00f8yere temperaturene og str\u00e5lingen p\u00e5 Venus. De fleste av instrumentene er basert p\u00e5 maskinvare som ble utviklet for Mars Express- og Rosetta-oppdragene.<\/p>","protected":false},"excerpt":{"rendered":"
