16. februarja bo satelit ESA z imenom Sentinel-3 poletel v orbito okoli Zemlje! Sentinel-3 je najnovej\u0161i v floti naprednih satelitov, katerih naloga je raziskovanje kopnega, oceanov in atmosfere na\u0161ega planeta.<\/p>\n<\/div>\n

Satelit Sentinel-3 se bo osredoto\u010dil na na\u0161e oceane. Ker oceani pokrivajo 70% povr\u0161ine planeta, nam njihovo spremljanje omogo\u010da, da preverimo, kako zdrava je Zemlja. Kar se dogaja v morjih, vpliva na nas ne glede na to, kje \u017eivimo. Voda na na\u0161em planetu je pomemben vir, ki ga moramo za\u0161\u010dititi.<\/p>\n

Satelit Sentinel-3 bo kro\u017eil v vi\u0161ini ve\u010d kot 800 km nad zemeljsko povr\u0161ino \u2013 to je \u0161e dlje od Zemlje kot Mednarodna vesoljska postaja, ki kro\u017ei okoli na\u0161ega planeta na vi\u0161ini pribli\u017eno 400 km. S tega razglednega mesta bo satelit meril temperaturo, barvo in vi\u0161ino morske povr\u0161ine ter debelino morskega ledu. Te meritve so zelo pomembne, saj jih lahko uporabimo za spremljanje sprememb morske gladine, obsega onesna\u017eenja in zdravstvenega stanja morskega \u017eivljenja.<\/p>\n

Ko Sentinel-3 ne bo spremljal oceana, bo pomagal svojemu satelitskemu kolegu Sentinel-2 pri opazovanju zemeljske povr\u0161ine. Meril bo vi\u0161ino jezer in rek ter celo spremljal nevarne gozdne po\u017eare.<\/p>\n

V orbiti sta \u017ee dva satelita Sentinel, po Sentinel-3 pa so na\u010drtovani \u0161e \u0161tirje. Vsak satelit bo deloval vsaj sedem let. Znanstveniki, ki sodelujejo pri misiji, pa upajo, da bodo delovali \u0161e dlje, zato so jim zagotovili dovolj goriva za 12 let neprekinjenega delovanja!<\/p>\n

Zanimiv podatek:<\/b> Raketa, ki bo Sentinel-3 ponesla v orbito, je predelana medcelinska balisti\u010dna raketa SS-19. Ta je bila prvotno zasnovana kot voja\u0161ko oro\u017eje, vendar je bila predelana za miroljubne namene. To je zelo primerno, glede na to, da je naloga Sentinel-3 za\u0161\u010dititi Zemljo!<\/p>","protected":false},"excerpt":{"rendered":"
