V zadnjih 40 letih so sateliti postali vse zmogljivej\u0161i in so sposobni opravljati \u0161tevilne razli\u010dne naloge.<\/p>\n<\/div>\n

Ve\u010dina vesoljskih plovil, ki jih izstreljuje evropska raketa Ariane-5, se uporablja za telekomunikacije \u2013 televizijo, digitalni radio, internet, video in telefonijo. Njihovi lastniki so obi\u010dajno velika mednarodna podjetja.<\/p>\n

Ve\u010dina drugih vesoljskih plovil je v lasti vlad in vesoljskih agencij, kot je ESA. Mnoga med njimi se uporabljajo za znanstvene raziskave.<\/p>\n

V zadnjih 25 letih so vesoljska plovila ESA preletela komet Halley, se umestila v orbito okoli Lune, Venere in Marsa ter raziskovala oddaljeni vesolje. Leta 2005 je sonda Huygens pristala na Saturnovem lunu Titanu. Leta 2014 bo Rosetta postala prvo vesoljsko plovilo, ki bo kro\u017eilo okoli kometa in na njegovi povr\u0161ini pristalo s sondo.<\/p>\n

Satelit SOHO in \u0161tirje sateliti iz programa Cluster so razkrili, kako deluje Sonce in kako vpliva na na\u0161 planet. Sateliti ERS in Envisat so prou\u010devali vse vidike Zemlje, od ledenih pokrovov in oceanov do ozonskega pla\u0161\u010da in rabe zemlji\u0161\u010d.<\/p>\n

Leta 2009 je bila uvedena nova serija misij Earth Explorer. Sateliti, kot so GOCE, SMOS in Cryosat, bodo izbolj\u0161ali na\u0161e razumevanje planeta Zemlja in vpliva \u010dlove\u0161kih dejavnosti na naravno okolje. Kmalu bo izstreljena dru\u017eina satelitov Sentinel, ki bo podrobno preu\u010devala kopno in oceane.
Vremenski sateliti Meteosat so spremenili na\u0161e vsakdanje \u017eivljenje. V naslednjih nekaj letih bo Evropa v orbito izstrelila \u2018konstelacijo\u2019 30 satelitov, imenovano Galileo, ki bo omogo\u010dala navigacijo in natan\u010dno dolo\u010danje polo\u017eaja kjerkoli na Zemlji.
Tudi Zdru\u017eene dr\u017eave, Rusija in nekatere evropske dr\u017eave upravljajo voja\u0161ke satelite. Oboro\u017eene sile jih uporabljajo za komunikacijo, opozarjanje na izstrelitve raket in nadzorovanje gibanja sovra\u017enih sil.<\/p>","protected":false},"excerpt":{"rendered":"
