Selvom vi normalt ikke l\u00e6gger m\u00e6rke til det, er Jordens magnetfelt meget vigtigt, da det beskytter os mod farlige solstorme og rumstr\u00e5ling. Uden det ville der ikke v\u00e6re noget liv p\u00e5 vores planet! For at kunne m\u00e5le denne magnetiske kraft med st\u00f8rre n\u00f8jagtighed end nogensinde f\u00f8r forbereder ESA sig p\u00e5 at sende en s\u00e6rlig mission i kredsl\u00f8b kaldet Swarm.<\/p>\n<\/div>\n<p>Swarm best\u00e5r af en konstellation af tre satellitter i tre forskellige pol\u00e6re baner i h\u00f8jder mellem 400 og 550 km. Hver satellit vil m\u00e5le styrken og retningen af Jordens magnetfelt.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"2500\" data-credit=\"ESA\/AOES Medialab\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2013\/10\/Earth_s_stormy_heart\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2013\/10\/earth_s_stormy_heart\/17911010-2-eng-GB\/Earth_s_stormy_heart.jpg\" alt=\"Earth\u2019s stormy heart\"><figcaption>Jordens stormfulde hjerte<\/figcaption><\/figure>\n<p>Forskere mener, at magnetfeltet skabes af v\u00e6ske i Jordens ydre kerne, men de forst\u00e5r stadig ikke fuldt ud, hvordan det opst\u00e5r, og hvordan det \u00e6ndrer sig over tid.<\/p>\n<p>For eksempel skifter placeringen af den nordlige og den sydlige magnetpol hele tiden. Magnetfeltets styrke \u00e6ndrer sig ogs\u00e5. Fra tid til anden skifter polerne faktisk plads, s\u00e5 den nuv\u00e6rende nordpol bliver til sydpolen. I s\u00e5danne tilf\u00e6lde vil et magnetkompas pege mod syd i stedet for mod nord! Forskerne h\u00e5ber, at Swarm-missionen vil kunne l\u00f8se disse og mange andre magnetiske mysterier.<\/p>\n<p>Swarm vil blive opsendt fra Plesetsk-kosmodromen i det nordlige Rusland den 22. november 2013.<\/p>","protected":false},"excerpt":{"rendered":"<p>There is an invisible magnetic field all around us.
