Den f\u00f6rsta personen som konstruerade en raket som anv\u00e4nde flytande br\u00e4nsle ist\u00e4llet f\u00f6r krut var en rysk l\u00e4rare vid namn Konstantin Tsiolkovsky. Det dr\u00f6jde mer \u00e4n 20 \u00e5r innan den f\u00f6rsta flygningen med en raket som drevs av flytande br\u00e4nsle \u00e4gde rum. Den 16 mars 1926 steg en liten raket, byggd av amerikanen Robert Goddard, till en h\u00f6jd av 12,4 meter under en flygning som varade i 2,5 sekunder.<\/p>\n<\/div>\n

Under de f\u00f6ljande \u00e5ren tog Tyskland ledningen inom raketutvecklingen. Resultatet blev V-2, en missil som anv\u00e4ndes f\u00f6r att attackera st\u00e4der som London mot slutet av andra v\u00e4rldskriget.<\/p>\n

\u00c5r 1945 b\u00f6rjade m\u00e5nga tyska raketforskare arbeta i USA eller Sovjetunionen. De bidrog till utvecklingen av st\u00f6rre och kraftfullare missiler som \u00e4ven kunde anv\u00e4ndas f\u00f6r rymdutforskning.<\/p>\n

Sputnik 1, v\u00e4rldens f\u00f6rsta satellit, sk\u00f6ts upp med en sovjetisk raket den 4 oktober 1957. Inom tio \u00e5r hade USA, under ledning av den tyske forskaren Wernher von Braun, byggt Saturn 5, som kunde transportera tre m\u00e4n till m\u00e5nen.<\/p>\n

Sedan 1979 har Europa utvecklat en serie Ariane-b\u00e4rraketer som h\u00f6r till de mest kraftfulla och p\u00e5litliga i v\u00e4rlden.<\/p>","protected":false},"excerpt":{"rendered":"
