"Like most earth-changing projects, more than one model was built for testing and back-up purposes. This is an original Sputnik from the '50s space program, named "model PS-1". Literally lost in space for the past 30 years, we discovered it hanging 20 feet above the ground in a science institute near Kiev. Nearly identical to the Sputnik that orbited the Earth. Constructed of a highly-polished metal alloy; 31" in diameter and equipped with two, 10ft and two 5ft whip antennae. Weighing in at 66lbs. Historians may note that this is lighter than the flown-craft, which weighed 176 lbs. This is because the once-top-secret radio transmitters and batteries were removed and destroyed, during the security conscious 1960s."
