Sputnik was a Soviet satellite. The Yanks made contact with the Soviets, brilliant. Did "Extra-Terrestrial" and "outer space" mean the same things in the 50s as they do now? e.g. We would not say that a communications satellite was extra-terrestrial, because it came from the Earth, but Americans in the 50s might say that it was, because it was not on the Earth.
