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 romferd kalt Swarm i bane rundt jorden.<\/p>\n<\/div>\n<p>Swarm best\u00e5r av en konstellasjon av tre satellitter i tre forskjellige polare baner i h\u00f8yder mellom 400 og 550 km.

Magnetfeltets styrke endrer seg ogs\u00e5. Fra tid til annen skifter polene faktisk 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>Swarm skal skytes opp fra Plesetsk-kosmodromen i Nord-Russland den 22. november 2013.<\/p>","protected":false},"excerpt":{"rendered":"<p>There is an invisible magnetic field all around us.
