I 1957 blev Sputnik den f\u00f8rste kunstige satellit, der med succes n\u00e5ede ud i rummet. Siden da er der blevet opsendt tusindvis af satellitter. Disse satellitter, der i dag kredser om vores planet, har givet os mulighed for at finde vej hjem hvor som helst fra, tale med mennesker over hele verden n\u00e5r som helst, overv\u00e5ge de forsvindende skove og iskapper og endda forudsige naturkatastrofer.<\/p>\n

Men satelliternes tidsalder har ogs\u00e5 fyldt rummet omkring Jorden med store stykker inaktivt metal. Der ansl\u00e5s at v\u00e6re 30.000 store stykker rumskrot, der kredser om planeten. Det omfatter alt fra udtjente satellitter, kasserede raketdele og endda astronauthandsker. Og dette tal stiger kun!<\/p>\n

Der findes ogs\u00e5 millioner af mindre affaldsstykker, s\u00e5som m\u00f8trikker, bolte og endda malingsflager. Mange af dem bev\u00e6ger sig rundt om Jorden med en hastighed p\u00e5 7 km i sekundet. Ved den hastighed kan et malingsflag have samme slagkraft som en motorcykel, der k\u00f8rer med 95 km i timen!<\/p>\n

Et s\u00e5dant sammenst\u00f8d ville beskadige enhver satellit eller rumstation og skabe nye stykker farligt rumskrot. Derfor har ESA sat nogle af sine dygtigste eksperter p\u00e5 sagen for at finde en l\u00f8sning p\u00e5 dette komplicerede problem. Og m\u00e5ske har de netop fundet den perfekte l\u00f8sning ved hj\u00e6lp af en af menneskehedens \u00e6ldste teknologier \u2013 fiskenettet.<\/p>\n

Ved hj\u00e6lp af specialdesignede net, der affyres fra rumfart\u00f8jer, vil vi kunne fange udtjente satellitter og bringe dem ned p\u00e5 jorden. Den geniale id\u00e9 gennemg\u00e5r i \u00f8jeblikket test i v\u00e6gtl\u00f8shed, og hvis alt g\u00e5r efter planen, vil ESA\u2019s mission \u2018e.Deorbit\u2019 blive iv\u00e6rksat i 2021, og s\u00e5 kan vi fange nogle satellitter!<\/p>\n

Sjovt faktum:<\/b> For at forblive i rummet og undg\u00e5 at styrte ned mod Jorden skal en satellit kredse om vores planet med en hastighed p\u00e5 mere end 28.200 kilometer i timen!<\/p>","protected":false},"excerpt":{"rendered":"
