Der gik mere end 20 \u00e5r, f\u00f8r den f\u00f8rste flyvning med en raket med flydende br\u00e6ndstof fandt sted. Den 16. marts 1926 steg en lille raket, bygget af amerikaneren Robert Goddard, til en h\u00f8jde p\u00e5 12,4 meter i en flyvning, der varede 2,5 sekunder.<\/p>\n<\/div>\n<p>I de f\u00f8lgende \u00e5r gik Tyskland i spidsen for raketudviklingen. Resultatet blev V-2, et missil, der blev brugt til at angribe byer som London mod slutningen af Anden Verdenskrig.<\/p>\n<p>I 1945 rejste mange tyske raketforskere til USA eller Sovjetunionen for at arbejde. De bidrog til udviklingen af st\u00f8rre og mere kraftfulde missiler, som ogs\u00e5 kunne anvendes til rumforskning.<\/p>\n<p>Sputnik 1, verdens f\u00f8rste satellit, blev opsendt med en sovjetisk raket den 4. oktober 1957.
