Sputnik 1 was launched during the International Geophysical Year from Site No.1/5, at the 5th Tyuratam range, in Kazakh SSR (now known as the Baikonur Cosmodrome). The density of the upper atmosphere could be deduced from its drag on the orbit, and the propagation of its radio signals gave data about the ionosphere. Tracking and studying Sputnik 1 from Earth provided scientists with valuable information. The word sputnik is Russian for satellite when interpreted in an astronomical context its other meanings are spouse or traveling companion. The launch was the beginning of a new era of political, military, technological and scientific developments. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth.
It was a polished metal sphere 58 cm (23 in) in diameter with four external radio antennas to broadcast radio pulses. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for two months until atmospheric drag caused it to fall back into the atmosphere on the 4th of January 1958. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program.
