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-konceptet 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 levere h\u00f8jpr\u00e6cise m\u00e5linger med h\u00f8j opl\u00f8sning af magnetfeltets styrke og retning. Mange af de f\u00f8lsomme instrumenter vil blive monteret p\u00e5 en 4 meter lang bom for at begr\u00e6nse interferens fra rumfart\u00f8jets elektriske systemer.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1238\" data-credit=\"ESA\u2013P.

For eksempel skifter de magnetiske nord- og sydpolers placering p\u00e5 overfladen konstant. Magnetfeltets styrke \u00e6ndrer sig ogs\u00e5. Fra tid til anden skifter polerne faktisk plads, s\u00e5 den nuv\u00e6rende nordpol bliver sydpolen. P\u00e5 s\u00e5danne tidspunkter 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>For at sikre, at m\u00e5lingerne bliver s\u00e5 n\u00f8jagtige som muligt, har alle satellitterne gennemg\u00e5et omfattende test. Nogle af disse blev udf\u00f8rt i et \u2018magnetisk rent\u2019 milj\u00f8 \u2013 et rum med tr\u00e6gulv, beliggende dybt inde i en tysk skov, langt v\u00e6k fra andre bygninger. N\u00e5r testprogrammet er afsluttet, vil Swarm-trioen blive leveret til den russiske rumhavn i Plesetsk, hvorfra den senere p\u00e5 \u00e5ret skal opsendes med en Rockot-raket.<\/p>","protected":false},"excerpt":{"rendered":"<p>There is an invisible magnetic field all around us.
