I \u00e5rhundraden har m\u00e4nniskor dr\u00f6mt om att l\u00e4mna jorden och resa till andra v\u00e4rldar. \u00c5r 1957 tog Sovjetunionen sedan det f\u00f6rsta lilla steget ut i rymden genom att skjuta upp en liten satellit, kallad Sputnik. Rymd\u00e5ldern hade b\u00f6rjat.<\/p>\n<\/div>\n

De tidiga rymdaktiviteterna dominerades av USA och Sovjetunionen. Med tiden l\u00e4rde sig dock \u00e4ven Europa och Japan att bygga egna satelliter och raketer. I dag utvecklar l\u00e4nder som Kina, Indien, Sydkorea, Israel och Brasilien sina egna rymdindustrier.<\/p>\n

Under de senaste 60 \u00e5ren har obemannade rymdsonder skickats ut mot alla planeter i solsystemet, liksom mot m\u00e5nga satelliter, asteroider och kometer. Rymdfarkoster har landat mjukt p\u00e5 ett halvt dussin himlakroppar, medan rovers har k\u00f6rt \u00f6ver ytorna p\u00e5 m\u00e5nen och Mars. \u00c4ven solen har utforskats ing\u00e5ende av en flotta av rymdfarkoster.<\/p>\n

M\u00e5nga rymdobservatorier, till exempel Hubble-teleskopet, har skickats upp f\u00f6r att studera den avl\u00e4gsna delen av universum. De har skickat tillbaka n\u00e5gra fantastiska bilder tagna i synligt ljus. Men de kan ocks\u00e5 observera stj\u00e4rnor och galaxer vid v\u00e5gl\u00e4ngder som \u00e4r osynliga f\u00f6r det m\u00e4nskliga \u00f6gat \u2013 radio-, infrar\u00f6d-, ultraviolett-, r\u00f6ntgen- och gammastr\u00e5lning. Den stora m\u00e4ngden uppt\u00e4ckter har f\u00f6r\u00e4ndrat v\u00e5rt s\u00e4tt att se p\u00e5 universum.<\/p>\n

Mer \u00e4n 500 personer har dessutom flugit i rymden sedan Jurij Gagarin banade v\u00e4g 1961. 20 personer har rest till m\u00e5nen och 12 av dem har vandrat p\u00e5 m\u00e5nen. Rymdstationer har byggts, och astronauter har l\u00e4rt sig att leva och arbeta i rymden under m\u00e5nga m\u00e5nader, eller till och med \u00e5r.<\/p>","protected":false},"excerpt":{"rendered":"
