Embora normalmente n\u00e3o o percebamos, o campo magn\u00e9tico da Terra \u00e9 muito importante, pois protege-nos de perigosas tempestades solares e da radia\u00e7\u00e3o espacial. Sem ele, n\u00e3o haveria vida no nosso planeta! Para medir esta for\u00e7a magn\u00e9tica com maior precis\u00e3o do que nunca, a ESA est\u00e1 a preparar-se para enviar para \u00f3rbita uma miss\u00e3o especial chamada Swarm.<\/p>\n<\/div>\n<p>O Swarm \u00e9 composto por uma constela\u00e7\u00e3o de tr\u00eas sat\u00e9lites em tr\u00eas \u00f3rbitas polares diferentes, a altitudes compreendidas entre 400 e 550 km.

A intensidade do campo tamb\u00e9m varia. De vez em quando, os p\u00f3los chegam mesmo a inverter-se, de modo que o atual p\u00f3lo norte se torna o p\u00f3lo sul. Nesses momentos, uma b\u00fassola magn\u00e9tica apontaria para sul em vez de para norte!
