1 out 1957 ano - Sputnik

Descrição:

Sputnik 1 was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It orbited for three weeks before its batteries ran out. The satellite then silently continued to orbit the planet for two months before it fell back into the atmosphere on 4 January 1958. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word "sputnik" is Russian for satellite when interpreted in an astronomical context; its other meanings are spouse or traveling companion.
