Eden najstarej\u0161ih delujo\u010dih satelitov agencije ESA bo kmalu umaknjen iz uporabe, potem ko je Zemljo obkro\u017eil skoraj 85.000-krat in preletel pribli\u017eno 3,8 milijarde km. Satelit European Remote Sensing 2 (ERS-2) je bil izstreljen leta 1995. ESA se je zdaj odlo\u010dila, da ga umakne iz uporabe, preden preneha delovati in postane nevarnost za druga vesoljska plovila.<\/p>\n<\/div>\n

Od 6. julija naprej bo vrsta v\u017eigov pogonskih motorjev postopoma zni\u017eevala njegovo orbito z 800 km na pribli\u017eno 550 km, kjer je tveganje za tr\u010denje z drugimi sateliti majhno. Namesto da bi ERS-2 postal del vesoljskih odpadkov, bo s\u010dasoma vstopil v Zemljino atmosfero in se tam se\u017egal.<\/p>\n

ERS-1 (ki je deloval med letoma 1991 in 2000) in njegov sestrski satelit sta imela dolgo in izjemno kariero. Skupaj sta v obdobju 20 let zagotavljala neprekinjen tok podatkov, s \u010dimer sta revolucionirala raziskave zemeljske atmosfere, kopnega, oceanov in polarnega ledu.<\/p>\n

Med njihovimi instrumenti je bil tudi prvi nevoja\u0161ki radar v vesolju. Ker je lahko opazoval povr\u0161ino v vseh vremenskih razmerah, podnevi in pono\u010di, je bil sposoben spremljati premike tal med mo\u010dnimi potresi ali vulkanskimi izbruhi. Prav tako je lahko izdeloval karte vi\u0161ine zemeljske povr\u0161ine.<\/p>\n

Drugi instrumenti so merili globalno temperaturo morske povr\u0161ine in spremembe morske gladine, kar so pomembne informacije za znanstvenike, ki raziskujejo podnebne spremembe. Drugi klju\u010dni poskus na satelitu ERS-2 je spremljal spreminjanje velikosti in lege ogromne luknje v ozonskem pla\u0161\u010du nad Antarktiko.<\/p>\n

Na podatkih ERS temelji na tiso\u010de raziskovalnih projektov in znanstvenih \u010dlankov. Podatki, ki jih je satelit poslal nazaj, so poglobili na\u0161e razumevanje delovanja Zemlje. Izbolj\u0161ane razli\u010dice instrumentov, ki so bili name\u0161\u010deni na njem, se zdaj uporabljajo v misijah, kot so Envisat agencije ESA, sateliti Earth Explorers in Sentinel.<\/p>","protected":false},"excerpt":{"rendered":"
