THE SOVIET UNION INAUGURATED THE “SPACE AGE” with its launch of Sputnik, the world’s first artificial satellite, on Oct. 4, 1957. Named Sputnik, the Russian phrase for “fellow traveler,” the spacecraft was launched at 10:29 p.m. Moscow time (7 hours ahead of New York/Washington) from the Tyuratam launch base in the Kazakh Republic. Sputnik, with a diameter of 22 inches and weight of 184 pounds, orbited Earth once every hour and 36 minutes. It was visible with binoculars during dawn and twilight, transmitting radio signals back to Earth strong enough that amateur radio operators detected them. While Sputnik’s launch was officially timed to correspond with the International Geophysical Year, a solar period that the International Council of Scientific Unions declared would be ideal for the launching of artificial satellites to study Earth and the solar system, it caught the U.S. government, military and scientific communities off-guard.
It was in this wake that NASA (the National Aeronautics and Space Administration was established, on October 1958, focusing on civil aerospace research.
