Brez njega na na\u0161em planetu ne bi bilo \u017eivljenja. Da bi to magnetno silo izmerili z ve\u010djo natan\u010dnostjo kot kdaj koli prej, se ESA pripravlja na izstrelitev posebne misije v orbito, imenovane Swarm.<\/p>\n<\/div>\n<p>Koncept \u00bbSwarm\u00ab obsega konstelacijo treh satelitov na treh razli\u010dnih polarnih tirnicah na vi\u0161inah med 400 in 550 km. Vsak satelit bo zagotavljal visoko natan\u010dne meritve mo\u010di in smeri magnetnega polja z visoko lo\u010dljivostjo. Mnogi ob\u010dutljivi instrumenti bodo name\u0161\u010deni na 4 metre dolgem iztegnjenem ro\u010daju, da se omeji motenje s strani elektri\u010dnih sistemov na vesoljskem plovilu.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1238\" data-credit=\"ESA\u2013P.

Na primer, polo\u017eaji severnega in ju\u017enega magnetnega pola na povr\u0161ini se nenehno spreminjata. Spreminja se tudi jakost polja. V\u010dasih se pola dejansko zamenjata, tako da sedanji severni pol postane ju\u017eni pol. V takih trenutkih bi magnetni kompas kazal na jug namesto na sever! Znanstveniki upajo, da bo misija Swarm lahko razre\u0161ila te in \u0161tevilne druge magnetne uganke.<\/p>\n<p>Da bi zagotovili \u010dim ve\u010djo natan\u010dnost meritev, so vsi sateliti prestali dolgotrajne teste. Nekateri od njih so bili izvedeni v \u2018magnetno \u010distem\u2019 okolju \u2013 v prostoru z lesenim podom, ki se nahaja globoko v nem\u0161kem gozdu, dale\u010d stran od vseh drugih stavb. Ko bo program testiranja zaklju\u010den, bo trojica satelitov Swarm dostavljena na rusko vesoljsko izstrelitveno plo\u0161\u010dad v Plesetsku, kjer jih bo \u0161e letos izstrelila raketa Rockot.<\/p>","protected":false},"excerpt":{"rendered":"<p>There is an invisible magnetic field all around us.
