ESA:s h\u00f6gteknologiska LISA Pathfinder-uppdrag sk\u00f6ts upp tidigare idag fr\u00e5n Europas rymdbas i Kourou i Franska Guyana. Med hj\u00e4lp av en kraftfull Vega-raket som sk\u00f6t upp LISA Pathfinder i rymden har uppdraget f\u00e5tt en utm\u00e4rkt start!<\/p>\n<\/div>\n

LISA Pathfinder ska unders\u00f6ka den kraft som hindrar oss fr\u00e5n att sv\u00e4va ut i rymden: gravitationen. F\u00f6r 100 \u00e5r sedan skrev den ber\u00f6mde forskaren Albert Einstein sin allm\u00e4nna relativitetsteori, som \u00e4r v\u00e5rt b\u00e4sta f\u00f6rs\u00f6k att f\u00f6rst\u00e5 hur gravitationen fungerar. LISA Pathfinder ska testa denna teori med hj\u00e4lp av otroligt k\u00e4nsliga instrument som kan uppt\u00e4cka sm\u00e5 krusningar i rymden.<\/p>\n

Ombord p\u00e5 LISA Pathfinder finns tv\u00e5 identiska kuber tillverkade av guld och platina. De kommer att sv\u00e4va fritt inuti rymdfarkosten utan att faktiskt vidr\u00f6ra den. Laserstr\u00e5lar som studsar mellan kuberna kommer att m\u00e4ta deras exakta positioner med en noggrannhet p\u00e5 en miljarddel av en millimeter! P\u00e5 s\u00e5 s\u00e4tt kommer forskarna att kunna ber\u00e4kna hur gravitationen p\u00e5verkar dem.<\/p>\n

\u00c4ven om uppdraget nu har inletts kommer det att dr\u00f6ja ytterligare 10 veckor innan det n\u00e5r sin optimala position. D\u00e4refter, efter de sista kontrollerna, kommer det att inleda sex m\u00e5naders otroligt exakta observationer som kan komma att f\u00f6r\u00e4ndra v\u00e5r f\u00f6rst\u00e5else av gravitationen.<\/p>\n

ESA:s forskare planerar redan f\u00f6r framtiden och hoppas kunna skjuta upp en uppf\u00f6ljningsmission, kallad eLISA, \u00e5r 2034. Denna mission kommer att forts\u00e4tta LISA Pathfinders arbete och hj\u00e4lpa oss att f\u00f6rst\u00e5 gravitationen b\u00e4ttre \u00e4n n\u00e5gonsin tidigare.<\/p>\n

Rolig fakta:<\/b> LISA Pathfinder har sm\u00e5 man\u00f6vreringsmotorer som kan avfyras 10 g\u00e5nger per sekund f\u00f6r att f\u00f6rhindra att rymdfarkosten kommer i kontakt med guld-platina-kuberna.<\/p>","protected":false},"excerpt":{"rendered":"
