Under de senaste 40 \u00e5ren har satelliterna blivit allt mer avancerade och kan nu fylla m\u00e5nga olika funktioner.<\/p>\n<\/div>\n

De flesta rymdfarkoster som skjuts upp med den europeiska Ariane-5-raketen anv\u00e4nds f\u00f6r telekommunikation \u2013 TV, digitalradio, internet, video och telefoni. De \u00e4gs vanligtvis av stora internationella f\u00f6retag.<\/p>\n

De flesta andra rymdfarkoster \u00e4gs av regeringar och rymdorganisationer som ESA. M\u00e5nga av dessa anv\u00e4nds f\u00f6r vetenskaplig forskning.<\/p>\n

Under de senaste 25 \u00e5ren har ESA:s rymdfarkoster flugit f\u00f6rbi Halleys komet, g\u00e5tt in i omloppsbana runt M\u00e5nen, Venus och Mars samt utforskat den avl\u00e4gsna delen av universum. \u00c5r 2005 landade sonden Huygens p\u00e5 Saturnus m\u00e5ne Titan. \u00c5r 2014 kommer Rosetta att bli den f\u00f6rsta rymdfarkosten som g\u00e5r in i omloppsbana runt en komet och landar en sond p\u00e5 dess yta.<\/p>\n

SOHO och fyra Cluster-rymdfarkoster har visat hur solen fungerar och hur den p\u00e5verkar v\u00e5r planet. ERS-satelliterna och Envisat har unders\u00f6kt alla aspekter av jorden, fr\u00e5n ist\u00e4cken och hav till ozonskiktet och markanv\u00e4ndningen.<\/p>\n

En ny serie Earth Explorer-uppdrag lanserades 2009. Satelliter som GOCE, SMOS och Cryosat kommer att \u00f6ka v\u00e5r f\u00f6rst\u00e5else f\u00f6r jorden och hur m\u00e4nsklig verksamhet p\u00e5verkar naturen. En serie Sentinel-satelliter kommer snart att skjutas upp f\u00f6r att i detalj kartl\u00e4gga land och hav.
V\u00e5r vardag har f\u00f6r\u00e4ndrats tack vare Meteosat-v\u00e4dersatelliterna. Under de n\u00e4rmaste \u00e5ren kommer Europa att skjuta upp en \u2018konstellation\u2019 best\u00e5ende av 30 satelliter, kallad Galileo, f\u00f6r navigering och exakt positionsbest\u00e4mning var som helst p\u00e5 jorden.
\u00c4ven USA, Ryssland och vissa europeiska l\u00e4nder har milit\u00e4ra satelliter i drift. Dessa anv\u00e4nds av f\u00f6rsvarsmakterna f\u00f6r kommunikation, varningar om missiluppskjutningar och f\u00f6r att spionera p\u00e5 fiendens truppr\u00f6relser.<\/p>","protected":false},"excerpt":{"rendered":"
