I \u00e5rhundreder havde mennesker dr\u00f8mt om at forlade Jorden og rejse til andre verdener. S\u00e5, i 1957, tog Sovjetunionen det f\u00f8rste lille skridt ud i rummet ved at opsende en lille satellit ved navn Sputnik. Rumalderen var begyndt.<\/p>\n<\/div>\n

De tidlige rumfartsaktiviteter blev domineret af USA og Sovjetunionen. Men med tiden l\u00e6rte ogs\u00e5 Europa og Japan at bygge deres egne satellitter og raketter. I dag er lande som Kina, Indien, Sydkorea, Israel og Brasilien i gang med at opbygge deres egne rumfartsindustrier.<\/p>\n

I l\u00f8bet af de sidste 60 \u00e5r er der blevet sendt ubemandede sonden ud mod alle planeterne i solsystemet samt mod mange m\u00e5ner, asteroider og kometer. Rumfart\u00f8jer har foretaget bl\u00f8de landinger p\u00e5 et halvt dusin himmellegemer, mens rovere har k\u00f8rt rundt p\u00e5 overfladen af M\u00e5nen og Mars. Ogs\u00e5 Solen er blevet udforsket i detaljer af en fl\u00e5de af rumfart\u00f8jer.<\/p>\n

Mange rumobservatorier, s\u00e5som Hubble-rumteleskopet, er blevet sendt ud i rummet for at unders\u00f8ge det fjerne univers. De har sendt nogle fantastiske billeder tilbage, der er taget i synligt lys. Men de kan ogs\u00e5 observere stjerner og galakser ved b\u00f8lgel\u00e6ngder, der er usynlige for det menneskelige \u00f8je \u2013 radiob\u00f8lger, infrar\u00f8dt lys, ultraviolet lys, r\u00f8ntgenstr\u00e5ler og gammastr\u00e5ler. Den enorme str\u00f8m af opdagelser har \u00e6ndret den m\u00e5de, vi ser p\u00e5 universet p\u00e5.<\/p>\n

Mere end 500 mennesker har desuden v\u00e6ret i rummet, siden Jurij Gagarin banede vejen i 1961. 20 mennesker har rejst til M\u00e5nen, og 12 af dem har g\u00e5et p\u00e5 M\u00e5nen. Der er blevet bygget rumstationer, og astronauterne har l\u00e6rt at bo og arbejde i rummet i mange m\u00e5neder eller endda \u00e5r.<\/p>","protected":false},"excerpt":{"rendered":"
