While there are only four known vintage replicas of the Sputnik-1 (two in private hands, one just outside Moscow at the Energia Corporate Museum, the company that descended from Korolev's Experimental Design Bureau, and one which does not have the internal components of that at Energia Corp, at the Museum of Flight in Seattle, Washington), we do not know of any other test models. An incredible and impressive artifact from the dawn of the space age.\n\nThe Sputnik-1 artificial satellite first orbited the Earth on October 5, 1957. Visible all around the Earth, it launched the American Sputnik crisis and gave birth to the Space Race.
