Sputnik was first launched by the Soviet Union on October 4, 1957. It is just crazy that it is Sputnik's 5oth anniversary; we have only been able to send technology into space for half a century! Sputnik sent a continuous signal to Earth for 23 days. Sputnik means "traveling companion". Sputnik was launched during the Cold War and scared the US into the Space race. Sputnik was a significant achievment that changed the world.
