Om du tittar mot v\u00e4ster efter en molnfri solnedg\u00e5ng under de kommande m\u00e5naderna kommer du inte att kunna undg\u00e5 att se en str\u00e5lande \u201caftonstj\u00e4rna\u201d. Men denna bl\u00e4ndande syn \u00e4r ingen stj\u00e4rna. Det \u00e4r planeten Venus, m\u00e5let f\u00f6r Europas senaste rymduppdrag till den yttre rymden.<\/p>\n<\/div>\n

Venus Express kommer att bli ESA:s f\u00f6rsta rymdfarkost som utforskar jordens n\u00e4stan identiska tvilling. Den ska skjutas upp ombord p\u00e5 en rysk Sojuz-raket i oktober 2005 och f\u00f6rv\u00e4ntas g\u00e5 in i omloppsbana runt Venus i april 2006.<\/p>\n

Rymdfarkosten kommer att flyga p\u00e5 en h\u00f6jd mellan 250 och 66 000 km \u00f6ver polerna och tillbringa tv\u00e5 venus\u00e5r (500 jorddagar) med att unders\u00f6ka det t\u00e4ta molnt\u00e4cket och atmosf\u00e4ren hos jordens n\u00e4rmaste planetgranne.<\/p>\n

Mer \u00e4n 20 ryska och amerikanska rymdfarkoster har skickats ut f\u00f6r att utforska den andra planeten fr\u00e5n solen, men m\u00e5nga g\u00e5tor kvarst\u00e5r:<\/p>\n

    Sju vetenskapliga instrument ombord p\u00e5 Venus Express ska f\u00f6rs\u00f6ka l\u00f6sa dessa g\u00e5tor.<\/p>\n

    Som namnet antyder konstruerades och byggdes Venus Express p\u00e5 bara tre \u00e5r \u2013 vilket \u00e4r mycket snabbt f\u00f6r en rymdsond avsedd f\u00f6r en planet. I likhet med ESA:s framg\u00e5ngsrika Mars Express-sond har rymdsonden anpassats f\u00f6r att klara de h\u00f6gre temperaturerna och str\u00e5lningen p\u00e5 Venus. De flesta av dess instrument bygger p\u00e5 h\u00e5rdvara som utvecklats f\u00f6r uppdragen Mars Express och Rosetta.<\/p>","protected":false},"excerpt":{"rendered":"
