Oppdraget, som benyttet en kraftig Vega-rakett for \u00e5 skyte LISA Pathfinder ut i verdensrommet, har f\u00e5tt en str\u00e5lende start!<\/p>\n<\/div>\n<p>LISA Pathfinder skal unders\u00f8ke kraften som hindrer oss i \u00e5 sveve ut i verdensrommet: tyngdekraften. For 100 \u00e5r siden skrev den ber\u00f8mte vitenskapsmannen Albert Einstein sin generelle relativitetsteori, som er v\u00e5rt beste fors\u00f8k p\u00e5 \u00e5 forst\u00e5 hvordan tyngdekraften virker. LISA Pathfinder skal teste denne teorien ved \u00e5 bruke utrolig f\u00f8lsomme instrumenter til \u00e5 oppdage bittesm\u00e5 krusninger i rommet.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1280\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2015\/12\/Artist_impression_of_LISA_Pathfinder\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2015\/12\/artist_impression_of_lisa_pathfinder\/17880328-2-eng-GB\/Artist_impression_of_LISA_Pathfinder.jpg\" alt=\"\"><\/figure>\n<p>Om bord p\u00e5 LISA Pathfinder finnes to identiske kuber laget av gull og platina. De vil sveve inne i romfart\u00f8yet uten \u00e5 v\u00e6re i fysisk kontakt med det. Laserstr\u00e5ler som reflekteres mellom kubene vil m\u00e5le deres n\u00f8yaktige posisjoner med en n\u00f8yaktighet p\u00e5 en milliarddel av en millimeter! Dette vil gj\u00f8re det mulig for forskerne \u00e5 beregne hvordan tyngdekraften virker p\u00e5 dem.<\/p>\n<p>Selv om oppdraget n\u00e5 er i gang, vil det ta ytterligere 10 uker f\u00f8r det n\u00e5r sin optimale posisjon. Deretter, etter de siste kontrollene, vil det innlede seks m\u00e5neder med utrolig presise observasjoner som kan endre v\u00e5r forst\u00e5else av tyngdekraften.<\/p>\n<p>Forskere ved ESA planlegger fremover og h\u00e5per \u00e5 kunne gjennomf\u00f8re en oppf\u00f8lgingsoppdrag, kalt eLISA, i 2034. Dette vil videref\u00f8re LISA Pathfinders oppdrag og bidra til at vi f\u00e5r en bedre forst\u00e5else av tyngdekraften enn noensinne.<\/p>\n<p><b>Et interessant faktum:<\/b> LISA Pathfinder har bittesm\u00e5 man\u00f8vreringsmotorer som kan avfyres 10 ganger i sekundet for \u00e5 hindre at romfart\u00f8yet kommer i kontakt med gull-platina-kubene.<\/p>","protected":false},"excerpt":{"rendered":"<p>ESA\u2019s high-tech LISA Pathfinder mission lifted off earlier today from Europe\u2019s spaceport in Kourou, French Guiana.
