De udf\u00f8rer mange forskellige opgaver. I mods\u00e6tning til biler er det sj\u00e6ldent, at man finder mere end 10 satellitter, der er ens. De fleste af dem er unikke og er hver is\u00e6r omhyggeligt samlet i h\u00e5nden. Alligevel er de alle designet og bygget p\u00e5 samme m\u00e5de.<\/p>\n<\/div>\n<p>En satellit best\u00e5r af to hoveddele: en platform (eller bus) og en nyttelast (instrumenter eller eksperimenter).<\/p>\n<p>Platformen udg\u00f8r den grundl\u00e6ggende metalkonstruktion. Den skal v\u00e6re st\u00e6rk, men samtidig let. Den omfatter det grundl\u00e6ggende skelet, som alt er bygget op omkring, samt rumfart\u00f8jets forskellige systemer \u2013 man\u00f8vreringsraketter, hovedmotor, br\u00e6ndstoftanke og str\u00f8mforsyning. Nyttelasten omfatter udstyret til kommunikation med jorden samt kameraer og andre videnskabelige instrumenter.<\/p>\n<p>Satellitens dele fremstilles mange forskellige steder. De sendes alle til \u00e9t center, hvor de samles og testes i specielle renrum. F\u00f8rst derefter sendes rumfart\u00f8jet til opsendelsescentret.<\/p>\n<p>Da der ikke findes garager i rummet, har mange satellitter deres egne \u2018reservedele\u2019 med om bord.
