I l\u00f8bet af de sidste 40 \u00e5r er satellitterne blevet stadig mere avancerede og i stand til at udf\u00f8re mange forskellige opgaver.<\/p>\n<\/div>\n

De fleste af de rumfart\u00f8jer, der opsendes med den europ\u00e6iske Ariane-5-raket, anvendes til telekommunikation \u2013 tv, digital radio, internet, video og telefoni. De ejes som regel af store internationale virksomheder.<\/p>\n

De fleste andre rumfart\u00f8jer ejes af regeringer og rumfartsorganisationer som f.eks. ESA. Mange af disse anvendes til videnskabelig forskning.<\/p>\n

I l\u00f8bet af de seneste 25 \u00e5r har ESA\u2019s rumfart\u00f8jer fl\u00f8jet forbi Halleys komet, g\u00e5et i kredsl\u00f8b om M\u00e5nen, Venus og Mars og udforsket det fjerne univers. I 2005 landede Huygens-sonden p\u00e5 Saturns m\u00e5ne, Titan. I 2014 vil Rosetta blive det f\u00f8rste rumfart\u00f8j, der g\u00e5r i kredsl\u00f8b om en komet og lander en sonde p\u00e5 dens overflade.<\/p>\n

SOHO og fire Cluster-rumfart\u00f8jer har vist, hvordan Solen fungerer, og hvordan den p\u00e5virker vores planet. ERS-satellitterne og Envisat har unders\u00f8gt alle aspekter af Jorden, lige fra iskapper og havene til ozonlaget og arealanvendelsen.<\/p>\n

I 2009 blev der lanceret en ny serie af Earth Explorer-missioner. Satellitter som GOCE, SMOS og Cryosat vil forbedre vores forst\u00e5else af Jorden og af, hvordan menneskelig aktivitet p\u00e5virker naturen. En serie af Sentinel-satellitter vil snart blive opsendt for at unders\u00f8ge landomr\u00e5der og havene i detaljer.
Vores hverdag er blevet forandret af Meteosat-vejrsatellitterne. I de kommende \u00e5r vil Europa opsende en \u2018konstellation\u2019 p\u00e5 30 satellitter, kaldet Galileo, der skal bruges til navigation og pr\u00e6cis positionsbestemmelse overalt p\u00e5 Jorden.
USA, Rusland og nogle europ\u00e6iske lande driver ogs\u00e5 milit\u00e6re satellitter. Disse anvendes af de v\u00e6bnede styrker til kommunikation, varsling om missilaffyringer og overv\u00e5gning af fjendtlige styrkers bev\u00e6gelser.<\/p>","protected":false},"excerpt":{"rendered":"
