Glossarbegriffe: Künstlicher Satellit
Description: Ein künstlicher Satellit ist ein vom Menschen geschaffenes Gerät, das in den Weltraum geschickt wird, um die Erde oder andere Objekte des Sonnensystems zu umkreisen, wo die Schwerkraft es in der Umlaufbahn hält. Künstliche Satelliten können für verschiedene Zwecke gebaut werden: z. B. für die Aufnahme von Luftaufnahmen der Erde, die Meteorologen bei der Wettervorhersage helfen, oder für die Aufnahme von Bildern astronomischer Körper und entfernter Galaxien. Künstliche Satelliten werden hauptsächlich auch für die weltweite Kommunikation und zur Positionsbestimmung eingesetzt, z. B. mit Satellitennavigationssystemen wie dem Global Positioning System (GPS). Der erste künstliche Satellit wurde 1957 von der Sowjetunion ins All geschickt und trug den Namen Sputnik 1.
