ESA\u2019s h\u00f8jteknologiske LISA Pathfinder-mission blev tidligere i dag sendt af sted fra Europas rumhavn i Kourou i Fransk Guyana. Missionen, hvor en kraftig Vega-raket sendte LISA Pathfinder ud i rummet, har f\u00e5et en fremragende start!<\/p>\n<\/div>\n

LISA Pathfinder skal unders\u00f8ge den kraft, der forhindrer os i at sv\u00e6ve ud i rummet: tyngdekraften. For 100 \u00e5r siden skrev den ber\u00f8mte videnskabsmand Albert Einstein sin generelle relativitetsteori, som er vores bedste fors\u00f8g p\u00e5 at forst\u00e5, hvordan tyngdekraften fungerer. LISA Pathfinder skal afpr\u00f8ve denne teori ved hj\u00e6lp af utroligt f\u00f8lsomme instrumenter, der kan registrere sm\u00e5 krusninger i rummet.<\/p>\n

\"\"<\/figure>\n

Om bord p\u00e5 LISA Pathfinder befinder der sig to identiske terninger fremstillet af guld-platin. De vil sv\u00e6ve inde i rumfart\u00f8jet uden faktisk at r\u00f8re ved det. Lasere, der sendes frem og tilbage mellem terningerne, vil m\u00e5le deres n\u00f8jagtige positioner ned til en milliarddel af en millimeter! Dette vil give forskerne mulighed for at beregne, hvordan tyngdekraften virker p\u00e5 dem.<\/p>\n

Selvom missionen nu er sat i gang, vil det tage yderligere 10 uger, f\u00f8r den n\u00e5r frem til den optimale position. Derefter, efter de sidste kontroller, vil den p\u00e5begynde seks m\u00e5neders utroligt pr\u00e6cise observationer, der kan \u00e6ndre vores forst\u00e5else af tyngdekraften.<\/p>\n

ESA\u2019s forskere planl\u00e6gger allerede nu og h\u00e5ber at kunne opsende en opf\u00f8lgningsmission, kaldet eLISA, i \u00e5r 2034. Denne mission vil videref\u00f8re LISA Pathfinders arbejde og hj\u00e6lpe os med at forst\u00e5 tyngdekraften bedre end nogensinde f\u00f8r.<\/p>\n

Sjovt faktum:<\/b> LISA Pathfinder er udstyret med sm\u00e5 raketmotorer, der kan affyres 10 gange i sekundet for at forhindre rumfart\u00f8jet i at ramme guld-platinkuberne.<\/p>","protected":false},"excerpt":{"rendered":"
