Prima persoan\u0103 care a proiectat o rachet\u0103 care folosea combustibili lichizi \u00een locul prafului de pu\u0219c\u0103 a fost un profesor rus pe nume Konstantin Tsiolkovsky. Au trecut mai mult de 20 de ani p\u00e2n\u0103 c\u00e2nd a avut loc primul zbor al unei rachete cu combustibil lichid. Pe 16 martie 1926, o mic\u0103 rachet\u0103 construit\u0103 de americanul Robert Goddard s-a ridicat la o \u00een\u0103l\u021bime de 12,4 metri \u00eentr-un zbor care a durat 2,5 secunde.<\/p>\n<\/div>\n

\u00cen anii care au urmat, Germania a devenit lider \u00een domeniul dezvolt\u0103rii rachetelor. Rezultatul a fost racheta V-2, care a fost folosit\u0103 pentru a ataca ora\u0219e precum Londra spre sf\u00e2r\u0219itul celui de-al Doilea R\u0103zboi Mondial.<\/p>\n

\u00cen 1945, mul\u021bi cercet\u0103tori germani specializa\u021bi \u00een rachete s-au angajat \u00een America sau \u00een Uniunea Sovietic\u0103. Ace\u0219tia au contribuit la construirea unor rachete mai mari \u0219i mai puternice, care puteau fi folosite \u0219i pentru explorarea spa\u021biului.<\/p>\n

Sputnik 1, primul satelit din lume, a fost lansat de o rachet\u0103 sovietic\u0103 pe 4 octombrie 1957. \u00cen decurs de 10 ani, Statele Unite, sub conducerea omului de \u0219tiin\u021b\u0103 german Wernher von Braun, au construit racheta Saturn 5, capabil\u0103 s\u0103 transporte trei oameni pe Lun\u0103.<\/p>\n

\u00cencep\u00e2nd din 1979, Europa a dezvoltat o serie de rachete de lansare Ariane, care se num\u0103r\u0103 printre cele mai puternice \u0219i mai fiabile din lume.<\/p>","protected":false},"excerpt":{"rendered":"
