In 1957, the world was surprised to see the Soviets1 launch the first satellite into orbit, with most expecting the USA to be the first to do so. The satellite, named Sputnik 1, transmitted a simple radio signal back to earth for 21 days and remained in orbit for a further 6 months. The USA responded to this great technological2 achievement by making the conquest of space a top national priority. This marked the beginning of the "space race".
