Historiska bilder av \u00e4ldsta satelliten<\/h2>\n\n\n\n

17 mars 1958 skickades den lilla “grapefrukt-satelliten” Vanguard 1 upp i rymden, den fj\u00e4rde satelliten \u00f6verhuvud taget. Fortfarande kan den ses och dokumenteras, drygt sextio \u00e5r senare. Den kommer att snurra runt jorden i ytterligare ett par hundra \u00e5r.<\/p>\n\n\n\n

H\u00e4r far Vanguard 1 fram \u00f6ver himlavalvet p\u00e5 en animerad sekvens som \u00e5terfinns p\u00e5 spaceweather-sajten.<\/a> Dubbeltryck p\u00e5 bilden och du f\u00e5r fram animationen, som \u00e4r kraftigt uppbromsad.<\/p>\n\n\n
