Selv om vi vanligvis ikke legger merke til det, er jordens magnetfelt sv\u00e6rt viktig, da det beskytter oss mot farlige solstormer og romstr\u00e5ling. Uten det ville det ikke v\u00e6rt noe liv p\u00e5 planeten v\u00e5r. For \u00e5 m\u00e5le denne magnetiske kraften med st\u00f8rre n\u00f8yaktighet enn noensinne, forbereder ESA seg p\u00e5 \u00e5 sende en spesiell romfart\u00f8y i bane rundt jorden, kalt Swarm.<\/p>\n<\/div>\n<p>Swarm-konseptet best\u00e5r av en konstellasjon av tre satellitter i tre forskjellige polare baner i h\u00f8yder mellom 400 og 550 km. Hver satellitt vil levere sv\u00e6rt n\u00f8yaktige m\u00e5linger med h\u00f8y oppl\u00f8sning av magnetfeltets styrke og retning. Mange av de f\u00f8lsomme instrumentene vil bli montert p\u00e5 en 4 meter lang bom for \u00e5 begrense forstyrrelser fra romfart\u00f8yets elektriske systemer.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1238\" data-credit=\"ESA\u2013P.

For eksempel forskyver de magnetiske nord- og s\u00f8rpolene seg kontinuerlig p\u00e5 overflaten. Ogs\u00e5 feltets styrke endrer seg. Fra tid til annen skjer det faktisk at polene bytter plass, slik at den n\u00e5v\u00e6rende nordpolen blir s\u00f8rpolen. I slike tilfeller vil et magnetkompass peke mot s\u00f8r i stedet for mot nord! Forskere h\u00e5per at Swarm-oppdraget vil kunne l\u00f8se disse og mange andre magnetiske mysterier.<\/p>\n<p>For \u00e5 sikre at m\u00e5lingene blir s\u00e5 n\u00f8yaktige som mulig, har alle satellittene gjennomg\u00e5tt omfattende tester. Noen av disse ble utf\u00f8rt i et \u2018magnetisk rent\u2019 milj\u00f8 \u2013 et rom med tregulv, dypt inne i en tysk skog, langt unna andre bygninger. N\u00e5r testprogrammet er fullf\u00f8rt, vil Swarm-trioen bli levert til den russiske romhavnen i Plesetsk, for oppskyting med en Rockot-rakett senere i \u00e5r.<\/p>","protected":false},"excerpt":{"rendered":"<p>There is an invisible magnetic field all around us.
