Show : What is a tatelliU? It's the payload containing of a multistage missile for instruments outer space Where a Dart U S i I i i I U Ul I 'I ' I i M I W is thrown 1000 yards and an ICBM 5000 miles a satellite is thrown so hard it keeps right on going What happens is that it is thrown out of the earth's dense atmosphere and given another burst of speed in space enough to balance the pull of gravity For example let's follow a flight of the Navy's Vanguard "which launched America's second satellite Unlike the Jupiter-- C which adapted missiles originally built for Vanmilitary purposes the three-stag- e guard was built from the ground up as a satellite launcher I " researching Hi exposing the third stage and the satellite After burnout the whole assembly coasts to an altitude of 300 miles There a rocket-poweturntable spins the third stage Special reverse rockets slow down the second stage and the third stage coasts clear When the third stage's path is roughly parallel to the earth's surface a delay fuse ignites its engine which powers the satellite to a speed of 18000 mph At burnout the satellite is sprung loose by a special explosive spring The path of the assembly when the third stage starts burning and its speed at burnout are critical for a successful orbit If still going away from the earth when ignited the satellite will make a narrow red its 4 I 11 GUARANTEED NOT TO SKIP ON ANY SURFACE!
